Description

Technical Field

[0001] [Cross - Reference to Related Applications] This application claims the benefit (priority) of U.S. Provisional Patent Application No. 62 / 957,103, filed on January 3, 2020. The disclosure of the prior application is considered a part of the disclosure of this application (incorporated herein by reference).

[0002] The present disclosure relates to a bed system, particularly to devices, systems, and methods for controlling the air flow and temperature of a bed.

Background Art

[0003] Generally, a bed is furniture used as a place to sleep or relax. Many modern beds include a soft mattress on a bed frame. The mattress may include springs, foam, and / or air chambers to support the weight of one or more occupants. Various features and systems have been used in combination with beds, including heating and cooling systems to heat and cool the bed's user.

Summary of the Invention

[0004] Some embodiments described herein include a bed system with microclimate (local climate) control capabilities for providing a high-quality sleep experience. The bed system may include a microclimate (local climate) control subsystem configured to supply conditioned air (e.g., heated or cooled air) to the mattress to achieve a desired temperature at the top of the mattress. In some implementations, the conditioned air may be supplied to one or more airflow pads positioned below the top of the mattress, thereby distributing the conditioned air to the top of the mattress through the airflow pads. Alternatively, the microclimate control subsystem may draw ambient air from the mattress, thereby regulating the temperature at the top of the mattress. For example, air may be forcibly drawn from the airflow pads so that air at the top of the mattress is drawn into the mattress, allowing the air at the top of the mattress to circulate and be refreshed. Providing the mattress system with air at a desired temperature using a conditioned air supply, or using air suction to expel heat from the mattress system, can provide precise microclimate (local climate) control in the mattress, thereby allowing for comfortable sleep.

[0005] In some implementations, a bed system may include an integrated high-airflow zone or layer, which may be implemented by one or more airflow pads positioned beneath the top layer of the mattress (e.g., the topper foam layer). For example, the airflow pad may be positioned (e.g., inserted) to replace at least a portion of the support foam layer beneath the top foam layer. The airflow zone allows for directed air intake from or supply to the mattress, particularly the top of the mattress. The material used for the airflow zone may be configured to allow air to move freely through it. In one example, the material may include a three-dimensional structure having elastic polyolefin fibers, such as Qshion® material. Other exemplary materials may include spacer monofilaments, mesh forms, and channeling.

[0006] In some implementations, the airflow layer may be wrapped and / or sealed with a membrane, at least partially, to allow directed air intake through it. The wrapping material may be configured to be air-impermeable or air-restrictive. For example, the wrapping may be made of PU, PVC, lined fibers, or other materials to help direct the air that should be drawn in through the membrane of the layer rather than the wrapping itself. Another example of wrapping material includes laminated materials. The wrapping may be made as a jacket that can be pulled up around the edges of the airflow layer material. In some implementations, a pull cord may be used for tightening or sewn in with a zipper.

[0007] In some implementations, the top surface of the airflow layer may be open without restriction. Alternatively, the top surface of the airflow layer may be constructed using a partially air-impermeable material to optimize where the majority of the air can be drawn from. For example, the top surface of the airflow layer may be configured to be more permeable near the center of the mattress (furthest from the fan's suction) to create a uniform surface. Alternatively, the top surface of the airflow layer may be constructed using an air-restricting material with zones of holes or punches to facilitate a direct flow of air. Perforation (punching) may be optional to help guide air in the desired manner.

[0008] Airflow zones or layers may be configured and positioned such that a large or significant amount of air can be drawn in from or supplied to the areas of the mattress where the most heat is accumulated. For example, the central part of the mattress (e.g., the area between the head and foot) can accumulate a lot of heat when a sleeper is resting on it. Therefore, an airflow zone may be located in the central part of the mattress.

[0009] Airflow zones or layers can consist of varying thicknesses. For example, airflow layers may be offered in different thicknesses, such as 0.5 inches or 2 inches, and can be selectively used to suit the desired purpose or result. Airflow zones can have different sizes within the mattress. For example, airflow zones may be formed from the edges of the bed to the center, and from the shoulder area to the knee area, to cover each sleeper. This configuration may allow for different zoning of the head / neck and feet. In alternative examples, airflow zones may be increased or decreased to help optimize effectiveness. In some implementations, airflow layers may be inserted (e.g., 2 inches) so as to be recessed from the edges or perimeter of the mattress. This configuration may allow the topper layer and rail foam to be laminated together, maintaining clean edges in the mattress. Furthermore, this configuration can create a finite cavity for the airflow layer to remain within.

[0010] The bed system may provide an air duct system coupled to an airflow layer, allowing air to flow (e.g., supply or draw in) from and into the airflow layer. For example, the air duct system may be configured to draw air from the airflow layer to under and out of the bottom of the mattress and foundation. The bed system may further include a fan assembly configured to push or draw air into and out of the airflow layer. The fan assembly may be mounted under the mattress foundation, and the air duct system may be fluidly connected to the fan assembly and routed through the foundation and partially through the mattress to the inlet of the airflow layer. In some implementations, the air duct system may be routed through a cut-out fan-shaped section of rail form surrounding the bed, thereby avoiding interference with the air chamber and its components (e.g., air hoses, wiring, etc.). Alternatively, the fan assembly and air duct system may be configured to be mounted and / or routed outside the foundation. This configuration may be advantageous when the fan assembly and air duct system are supplied separately from the bed system and later assembled with the bed system.

[0011] A bed system with an airflow layer can operate to dissipate and remove heat that would normally accumulate within the comfort layer (e.g., the topper layer), thereby effectively regulating the microclimate (local climate) of the mattress system. Furthermore, a bed system with an airflow layer can operate to draw ambient air from the room into the top of the mattress, replacing (substituting) warm air, bringing a calming refresh to the microclimate and comfort materials within the mattress. In addition, a bed system with an airflow layer can provide humidity control, which is another element of comfortable sleep. The airflow layer is configured and positioned within the mattress so that the comfort and durability of the mattress are not affected by the airflow layer.

[0012] In some implementations, the fan assembly may provide temperature control functionality. For example, the fan assembly may include a temperature sensor (e.g., a thermocouple) configured to directly monitor the heat drawn from the mattress. The monitored temperature may be a direct reflection of the microclimate and the temperature of the mattress system. The temperature sensor may be placed in various locations, such as within the air duct system. The fan assembly may have a variable CFM to control the amount of heat removed from the bed system. In some implementations, the bed system may operate with closed-loop control. For example, thermal events may be monitored for a predetermined period (e.g., overnight) by briefly turning on the airflow system to collect thermal data from, for example, the sleeping environment. The thermal data thus collected may be sent into the system for adjustment to the control.

[0013] In some implementations, the fan assembly may be configured as a thermal module for heating, cooling, and air movement. For example, the thermal module may include one or more fans, an electronic circuit board for onboard control, and a heating element (heating body). The thermal module may further include guards or screens over openings (e.g., air inlet and outlet openings) to provide safe operation and prevent foreign matter (e.g., dust, particles, etc.) from entering the housing of the thermal module. In some implementations, the thermal module may include one or more reversible electric fans, one or more unidirectional axial fans, one or more radial fans, or any combination thereof, for moving air in and out of the mattress. The heating element may be positioned in or near the airstream to supply warmed air to the mattress. The heating element may be smaller than the total air passage area to allow for increased airflow in the system in air intake mode, but to allow for adequate airflow and temperature rise in heating mode. The cooling element may be placed in or near the airstream to supply cooled air to the mattress.

[0014] In some implementations, the thermal module may include one or more measures of sound and / or vibration damping mechanisms. In some examples, such sound and / or vibration damping mechanisms may include adhesive foam placed on the inside of the housing and / or adhesive masking tape (e.g., butyl tape) placed on the inside or outside of the housing. Additionally or alternatively, sound and / or vibration damping mechanisms may include assemblies of mass and foam that may be placed on the inside or outside of the housing and / or partially or completely installed within the airstream. Additionally or alternatively, sound and / or vibration damping mechanisms may include reinforcing ribs placed within the housing to minimize the drumming effect of air pulsations. Such ribs may be tuned to reinforce the housing to ensure that the housing's natural frequencies do not overlap with or approach the forced vibration frequencies supplied by the fan.

[0015] The fan within the thermal module may be isolated from the housing of the thermal module and / or the base of the mattress to which the thermal module is mounted. Various methods can be used for such isolation. In some examples, adhesive foam strips may be used to provide a compression or friction fit between the housing and the fan. Additionally or alternatively, molded foam strips may be provided to engage the ribs in the housing with the ribs / mounting features of the fan to mechanically bond them together, while still isolating vibrations caused by the fan. Additionally or alternatively, molded elastomer strips may be provided to engage the ribs in the housing with the ribs / mounting features of the fan to mechanically bond them together, while still isolating vibrations caused by the fan.

[0016] The thermal module may include a thermal protection circuit that is specific to the heating element and may be configured to prevent the unit from overheating above the designed maximum temperature. In some implementations, the thermal module may include two thermostats placed in series within a circuit that supplies power to the heating element. The heating circuit may be either a DC or AC power supply of the desired voltage. The thermostats may be placed directly on the heating element, wedge-shaped between the fins of the heating element, and / or placed near the heating element. The heating element may operate in closed-loop control by, for example, measuring the outlet temperature and adjusting the heating power (e.g., reducing or increasing) to achieve the desired outlet temperature.

[0017] The thermal module may include two temperature sensors (e.g., thermocouples) within its housing. For example, these sensors may be positioned on the opposite side of the heating element. These temperature sensors may be used to verify the function of the fan, the function of the heating element, the output of the heating element, and / or the direction of the airflow. These sensors may be used to verify these functions during normal operation, at the end of line testing during manufacturing, and / or during troubleshooting or diagnostic operations.

[0018] The thermal module may include one or more integrated thermocouples that measure the extraction temperature of the mattress microclimate, compare it to the ambient temperature, and measure and react to the amount of heat extracted from the mattress microclimate.

[0019] The microclimate of a bed system can be controlled in a closed loop. Multiple methods can be employed to provide closed-loop microclimate control. Generally, such methods include the steps of measuring the temperature of the microclimate and increasing or decreasing heating or cooling to obtain a desired microclimate temperature or energy load / extraction. For example, in heating mode, warm air is pushed into the microclimate through the mattress, and a fan may be periodically reversed to draw air from the microclimate to "sample the temperature" and react accordingly (e.g., increase or decrease heating / cooling). Alternatively or additionally, an additional fan may be activated periodically or continuously to draw in small amounts of air (less than that supplied to the microclimate) for measurement and corresponding reaction (e.g., increase or decrease heating / cooling). In cooling mode, microclimate air is extracted from the mattress, and one or more thermocouples within the thermal module are used to measure the temperature as described above, thereby providing a partial level of "closed-loop microclimate" control.

[0020] In some implementations, the bed system may include air supply and air return. Air supply and air return can be used to introduce ambient or conditioned air to specific points or areas of the mattress, and to return air from other points or areas of the mattress. This configuration can provide nearly complete control of airflow over the sleeper's entire body on the mattress, potentially increasing cooling and / or heating performance. Furthermore, air supply and air return at different locations can provide the ability to circulate warm or suctioned air over the user's entire body, rather than just localized zones. Additionally, this configuration can provide the ability to circulate externally cooled air over the user's entire body, as opposed to ambient air circulation. This could be a way to increase the sensation of coolness and further enhance cooling performance without increasing airflow / noise / interruption. A bed system with separate air supply and return points can provide nearly 100% closed-loop control, as both the supply and return air are controllable, allowing for the measurement of true microclimate temperature variations. For example, air changes its temperature as it flows over the body (whole) between the supply and return points, resulting in a "zone" sensation where the most extreme zones occur where the air enters the mattress, while the extreme zones are less pronounced where the air leaves the mattress.

[0021] In several implementations, the bed system may offer various ways to keep the air duct fixed and maintain the structural integrity of the mattress rail. For example, a piece of material may be attached to the inside of the rail to securely hold the air duct in place. Additionally or alternatively, a channel cut may be provided through the rail form for the air duct to pass through, thereby preventing the duct from being pulled outwards from the rail.

[0022] Fans within a bed system can be reversible. When air is introduced into the sleep system, an energy source can be used to heat the moving air. This allows the same system to effectively heat or cool without requiring special piping or additional systems.

[0023] In some implementations, the plenum (e.g., air duct) that draws air from the insert can be optimized to draw in the maximum amount of air with the minimum constraints. For example, the plenum may be configured in a "funnel" design to provide optimal air intake and / or optimal air supply.

[0024] In some implementations, a sleeve may be provided for connection to an airflow pad, extending therefrom and surrounding an air duct coupled to the airflow pad. The sleeve may help reduce air leakage through this connection and may also help hold the duct in place.

[0025] In some implementations, airflow pads may be separated into different zones within the mattress, and may be of different sizes within the mattress to control where thermal performance is directed. Airflow pads may be attached to a paired assembly to ensure they remain in place. This may be done via adhesive, tape, or another type of attachment method. Routing of hoses for air chambers within the air mattress may involve creating "jogs" (overhangs) or offsets to avoid interference with the routing of air ducts from the airflow pads.

[0026] In some implementations, the bed system may provide various forms to minimize the dB level of the system. For example, fans and ducts can be arranged within the base to help block noise. Additionally or alternatively, a jacket or insulation wrap can be arranged around the fans and ducts. Additionally or alternatively, a muffler can be incorporated to minimize the exhaust noise of the air. Additionally or alternatively, a special foam can be used near the air inlet to help mitigate the noise of the air flow.

[0027] The air flow zone or layer can be used with a separate foot warming layer within the mattress. For example, the foot warming layer can be arranged or attached to the foot portion of the mattress and can be configured with one or more heating elements that are independently controlled. The air flow zone can be provided in other parts of the mattress, such as the central part, and microclimate control can be provided independently in both the air flow zone and the foot portion. Further, the air flow zone can be selectively operated in multiple operating modes. For example, the air flow zone can be selectively operated in a cooling mode, a heating mode, a cleaning mode, a refresh mode, and a preparation mode.

[0028] The bed system described herein can be configured to control the microclimate of the mattress to limit the deviation of the internal pressure of the air mattress, thereby providing consistent comfort while the mattress is operating in the heating mode or the cooling mode. For example, when the air mattress is actively controlled during heating or cooling operations, the pressure within the air chambers of the mattress may change, which may result in a deviation from the set value of the air pressure. The bed system can limit the amount of change in air pressure that can be brought about by such active heating or cooling operations. For example, the bed system can limit the amount of energy input into the system or the amount of energy removed from the system, thereby reducing or eliminating the deviation from the set value of the air pressure.

[0029] Additionally or alternatively, the bed system may control the microclimate of the mattress and compensate for the thermal effects of a user resting on the mattress. For example, a sleeper generates body heat, and such heat output may heat the air chambers of the mattress, thereby causing a pressure increase in the air chambers. The pressure change in the air chambers may cause a deviation from a pressure setpoint that is selected by the sleeper or automatically determined based on one or more factors to provide a personal level of comfort. For example, the pressure within the air chambers of the mattress may deviate from the setpoint due to the heat output from the user's body. The bed system may offset the heat input to the bed from an active heating or cooling system based on the amount of the thermal effect of the user's body resting on the bed, thereby minimizing the deviation from the setpoint of the air pressure within the air chambers of the mattress and ensuring a consistent level of comfort for the bed.

[0181] [Overview of bed structure with airflow pad] Figure 1 shows an exemplary bed system 100 for providing a high-quality sleep experience in an exemplary local bed system 101. The local bed system 101 may comprise a bed 102 and a bed control system 110 used with the bed 102 and configured to control one or more user comfort functions of the bed 102.

[0182] The bed 102 may comprise a mattress 104 and a base 106. In some embodiments, the mattress 104 may be an air mattress having an inflatable air chamber and a controller for controlling the inflation of the inflatable air chamber. In other embodiments, the mattress 104 does not include an air chamber. For example, the mattress 104 may include foam and / or springs instead of, or in addition to, an inflatable air chamber. The mattress 104 may be sized and molded as a twin mattress, a full mattress, a queen mattress, a king mattress, a California king mattress, a split king mattress, a partially divided mattress (e.g., a mattress divided at the head and / or foot ends and joined in the middle), and / or other mattresses suitable for the application. The base 106 is positioned beneath the mattress 104 to support the mattress 104. In some embodiments, the base 106 may be an adjustable base having one or more articulated parts for lifting the base 106 and the head and foot portions of the mattress 104, etc. In other embodiments, the base 106 may be a stationary base.

[0183] The bed 102 may be configured to provide microclimate control of the mattress 104. In some implementations, the bed 102 provides a foot warming function. For example, the bed 102 may include a foot warmer 120, which is positioned on the mattress 104 or incorporated into the foot side of the bed 102 within the mattress 104. The foot warmer 120 may be positioned on the top of the mattress 104, incorporated within the mattress 104, positioned elsewhere on the bed 102, and / or positioned in other forms. In some implementations, the foot warmer 120 may include an electronic heating element. In other embodiments, the foot warmer 120 may include an air circulation element through which heated air is circulated. Other forms are also possible.

[0184] Additionally or alternatively, the bed 102 may be configured to provide body cooling / heating functions. For example, the bed 102 may include an airflow insertion pad 122, which may be contained within the mattress 104 and configured to circulate ambient or regulated air through the mattress under the user at rest. The airflow insertion pad 122 may be positioned at various locations within the mattress 104. In the illustrated example, the airflow insertion pad 122 is positioned between the head and foot of the mattress 104 (for example, in the center of the mattress).

[0185] The bed control system 110 operates to control the functions available to the bed 102. In some implementations, the bed control system 110 includes a bed joint movement system 112, an air chamber control system 114, a foot warming control system 116, and an airflow insertion pad control system 118.

[0186] The bed joint movement system 112 operates to articulate the base 106 and / or mattress 104. For example, the bed joint movement system 112 may adjust one or more articulated parts of the base 106 to raise the head and foot of the base 106 and / or mattress 104. The bed joint movement system 112 may include a controller and actuators (e.g., motors) actuated by the controller and coupled to the articulated parts of the base 106 so that the parts of the base 106 are automatically adjusted to the desired position. Alternatively or additionally, the articulated parts of the base 106 may be adjusted manually.

[0187] The air chamber control system 114 operates to control the air chamber of the mattress 104. The air chamber control system 114 may include a controller and an actuator (e.g., a pump) that is actuated by the controller and fluidly connected to the air chamber. The actuator is controlled to inflate or deflate the air chamber to provide and maintain a desired pressure within the air chamber, thereby providing a desired firmness in the air chamber.

[0188] The foot warming control system 116 operates to control a foot warming device 120 located within the mattress 104. The foot warming control system 116 may include a controller configured to activate the heating elements of the foot warming device 120 and maintain a desired temperature for the heating elements.

[0189] The airflow insertion pad control system 118 operates to control an airflow insertion pad 122 positioned within the mattress 104. The airflow insertion pad control system 118 may include an air controller configured to allow ambient air or conditioned air to flow into or out of the airflow insertion pad 122 so that the top layer of the mattress above or next to the airflow insertion pad 122 has a desired temperature and / or humidity.

[0190] In some implementations, the bed joint movement system 112, the air chamber control system 114, the foot warming control system 116, and the airflow insertion pad control system 118 can be configured and operated independently. In other implementations, some or all of the bed joint movement system 112, the air chamber control system 114, the foot warming control system 116, and the airflow insertion pad control system 118 are combined at least partially so as to share at least some of their components, such as actuators (e.g., motors, pumps, etc.) and / or controllers (e.g., control circuits, processors, memory, network interfaces, etc.).

[0191] The bed control system 110 can be accessed by the user via one or more control devices 130, such as a bedside controller 132 and a mobile computing device 134. The bedside controller 132 is wired or wirelessly connected to the bed control system 110 and allows the user to control the bed control system 110 at least partially. The bedside controller 132 includes an input device (e.g., a keypad, buttons, switches, etc.) for receiving user input to control various settings of the bed control system 110, such as joint positions, temperature setpoints, and air chamber pressure setpoints. The bedside controller 132 may further include an output device (e.g., a display, speaker, etc.) for outputting the state and status of the bed control system 110, as well as other information useful to the user, such as joint positions, temperature setpoints, air chamber pressure setpoints, and sleep analysis results. The same or similar functions can also be implemented using a mobile computing device 134, such as a mobile device running a dedicated software application. For example, the user can use the mobile device as an input device to control various settings of the bed control system 110, such as joint position, temperature setting value, and air chamber pressure setting value. Furthermore, the user can use the mobile device as an output device to view the state and status of the bed control system 110, as well as other useful information such as joint position, temperature setting value, air chamber pressure setting value, and sleep analysis results.

[0192] Referring further to Figure 1, system 100 may include a server system 140 connected to a local bed system 101 and configured to provide one or more services associated with bed 102. The server system 140 may be connected to the local bed system 101 via a network 142, such as bed 102, bed control system 110, and / or control device 130. The server system 140 may take various forms, such as a local server system having one or more computing devices dedicated to one or more beds, or a cloud server. Network 142 is an electronic communication network that facilitates communication between the local bed system 101 and the server system 140. An electronic communication network is a set (or pair) of computing devices and links between such computing devices. The computing devices in the network use the links to enable communication between the computing devices in the network. Network 142 may include routers, switches, mobile access points, bridges, hubs, intrusion detection devices, storage devices, standalone server devices, blade server devices, sensors, desktop computers, firewall devices, laptop computers, handheld computers, mobile phones, and other types of computing devices. In various embodiments, Network 142 includes various types of links. For example, Network 142 includes wired links and / or wireless links. Furthermore, in various embodiments, Network 142 is implemented on various scales. For example, Network 142 may be implemented as one or more local area networks (LANs), metropolitan area networks, subnets, wide area networks (such as the Internet), or on other scales.

[0193] In some implementations, the server system 140 may provide a bed data service that can be used by a data processing system associated with the local bed system 101. The server system 140 may be configured to collect sensor data and sleep data from a particular bed and to match the sensor data and sleep data with one or more users who were using the bed when the sensor data and sleep data were generated. The sensor data and sleep data, as well as the matching data, may be stored in a database as bed data 150. The bed data 150 may include user identification data that can be used to identify the user of the bed. Users may include customers, owners, or other users registered with the server system 140 or another service. Each user may have, for example, a unique identifier, user credentials, contact information, billing information, demographic information, or any other technically appropriate information. The bed data 150 may include administrative data that can be used to identify data related to beds or other products associated with the data processing system. For example, a bed may include a product sold or registered with the system associated with the server system 140. Each bed may have, for example, a unique identifier, model and / or serial number, sales information, geographical information, delivery information, a list of associated sensors and control peripherals, etc. Additionally, one or more indices stored in the bed data 150 may identify the user associated with the bed. For example, this index may record the sale of one bed to one user, multiple users sleeping in one bed, etc. The bed data 150 may include sensor data that records raw or condensed sensor data recorded by the bed equipped with an associated data processing system. For example, the bed's data processing system may include a temperature sensor, a pressure sensor, and a light sensor.The readings from these sensors, whether in the form of raw sensor data or in a format generated from the raw sensor data (e.g., sleep metrics), can be communicated by the bed data processing system to the server system 140 and stored in the bed data 150. Additionally, one or more indices stored by the server system 140 may identify the user and / or bed associated with the sensor data. In some implementations, the server system 140 may use any of its available data to generate advanced sleep data. This advanced sleep data includes sleep metrics and other data generated from the sensor readings. Some of these calculations may be performed on the server system 140 instead of locally on the bed data processing system, for example, because the calculations are computationally complex or require a large amount of memory space or processor power that is not available to the bed data processing system. This may help allow the bed system to be part of a system that operates with a relatively simple controller and performs relatively complex tasks and calculations.

[0194] Additionally or alternatively, the server system 140 may provide a sleep data service that can be used by a data processing system that may be associated with the local bed system 101. In this example, the server system 140 is configured to record data related to the user's sleep experience and store such data as sleep data 152. The sleep data 152 may include pressure sensor data related to the configuration and operation of pressure sensors in the bed. For example, the pressure sensor data may include identifiers of the type of sensor in a particular bed, their settings and calibration data, etc. The sleep data 152 may also include pressure-based sleep data that can be calculated based on the raw pressure sensor data and can represent sleep metrics specifically associated with that pressure sensor data. For example, the user's presence, movement, weight change, heart rate, and respiratory rate may be determined from the raw pressure sensor data. Furthermore, one or more indices stored by the server system 140 may identify the user associated with the pressure sensor, the raw pressure sensor data, and / or the pressure-based sleep data. The sleep data 152 may include non-pressure sleep data that can be calculated based on other data sources and may represent sleep metrics obtained from such other data sources. For example, user-entered preferences, light sensor readings, and acoustic sensor readings may all be used to track the sleep data 152. Additionally, one or more indices stored by the server system 140 may identify users associated with other sensors and / or non-pressure sleep data 152.

[0195] Additionally or alternatively, the server system 140 may provide a user account service that can be used by a data processing system that may be associated with the local bed system 101. For example, the server system 140 may record a list of users, identify other data associated with those users, and store such data as user account data 154. The user account data 154 is associated with users of beds with associated data processing systems. For example, users may include customers, owners, or other users registered with the server system 140 or another service. Each user may have, for example, a unique identifier, user credentials, demographic information, or any other technically appropriate information. The user account data 154 may include contractual data that can be used to track the user's interactions with the bed and / or cloud service manufacturers, vendors, and / or administrators. This contractual data may include communications (e.g., emails, service calls), data from sales (e.g., sales receipts, configuration logs), and social network interactions. User account data 154 may include usage history data relating to the user's interactions with one or more applications and / or the bed's remote control. For example, monitoring and configuration applications may be distributed to run on, for example, the control unit 130. These applications may log and report user interactions for storage. Furthermore, one or more indices stored by the server system 140 may identify the user associated with each log entry.

[0196] Additionally or alternatively, the server system 140 may provide environmental services that can be used by a data processing system that may be associated with the local bed system 101. For example, the server system 140 may record data related to the user's home environment and store such data as environmental data 1546. Environmental data 156 may be acquired using one or more sensors installed inside or around the bed. Such sensors may be of various types that can detect environment variables, such as light sensors, noise sensors, vibration sensors, and thermostats. Environmental data 156 may include historical readings or reports from these sensors. As an example, a light sensor may be used to collect data indicating the frequency and duration of instances (events) of increasing lighting while the user is sleeping.

[0197] An exemplary mattress system 200 is described with reference to Figures 2 to 10. The mattress system 200 can be used to implement the mattress 104 shown in Figure 1.

[0198] Figure 2 is a bottom-side perspective view of the mattress system 200, showing the mattress system 200 upside down. The mattress system 200 may comprise a top layer (e.g., a first layer) 202, an intermediate layer (e.g., a second layer) 204, a rail structure 206, and a bottom layer (e.g., a third layer) 208. In some implementations, the top layer 202, intermediate layer 204, and bottom layer 208 are arranged sequentially from top to bottom of the mattress system 200. The rail structure 206 is positioned around the mattress system 200 and is configured to at least partially surround the air chamber assembly 220 (Figure 3). As shown in Figure 2, the bottom layer 208 may be positioned so as to be at least partially surrounded by the rail structure 206. The bottom layer 208 may be configured to close off the space 210 (Figure 3) defined by the rail structure 206. In other implementations, the bottom layer 208 may be configured and placed on top of the rail structure 206.

[0199] Figure 3 is an exploded view of the mattress system 200 of Figure 2 (displayed upside down). The mattress system 200 may include an air chamber assembly 220. In the illustrated example, the air chamber assembly 220 includes a pair of air chambers 222 positioned between the top layer 202 and the bottom layer 208. The air chambers 222 may be positioned to be surrounded by a rail structure 206. The air chamber assembly 220 may further include a pump system 224 (Figures 10 and 19) configured to inflate and / or deflate the air chambers 222.

[0200] The mattress system 200 further includes an airflow layer 230 configured to distribute ambient air or regulated air through it to the top layer 202 and / or draw ambient air or regulated air through it from the top layer 202. The airflow layer 230 may include one or more airflow pad assemblies 232. An example of an airflow pad assembly 232 is described herein in more detail with reference to, for example, Figures 11 to 13. The airflow layer may also be referred herein as an airflow distribution layer, an air distribution layer, or other similar terms. The airflow pad assembly may also be referred herein as an airflow pad, an airflow insertion unit, or other similar terms.

[0201] As shown in Figure 3, the rail structure 206 may be positioned on the intermediate layer 204 and may define a space 210 for at least partially receiving the air chamber assembly 220. The bottom layer 208 may be positioned at least partially within the space 210 and may at least partially cover the space 210 and the air chamber assembly 220 within the space 210.

[0202] The top layer 202, the intermediate layer 204, the rail structure 206, and the bottom layer 208 can be manufactured from a variety of materials. For example, at least one of the top layer 202, the intermediate layer 204, the rail structure 206, and the bottom layer 208 can be manufactured from a foam that may be closed-cell, open-cell, or a combination thereof. Other materials such as one or more coil springs, air chambers, spacer materials, and / or other suitable materials may also be used for at least one of the top layer 202, the intermediate layer 204, the rail structure 206, and the bottom layer 208.

[0203] Figure 4 is an exploded view of the mattress system 200 of Figure 2 (displayed upside down), showing the top layer 202 and the intermediate layer 204. The top layer 202 has a top surface 212 (opposite the bottom surface 214), on which the user's body can be placed directly or indirectly through a mattress cover and / or one or more additional layers placed on the top surface. The intermediate layer 204 may be positioned on the opposite side of the top layer 202 from the top surface 212. For example, the top layer 202 has a bottom surface 214 on the opposite side of the top surface 212, and the intermediate layer 204 is positioned on the bottom surface 214 of the top layer 202. The intermediate layer 204 can be attached to the top layer 202 in various ways. For example, the intermediate layer 204 may be bonded to the top layer 202, or attached to the top layer 202 using fasteners such as hook-and-loop fasteners (e.g., VELCRO®), zippers, clips, pins, buttons, straps, cords, snap fasteners, and other suitable types of fasteners.

[0204] In some implementations, the intermediate layer 204 provides a notch 240 configured to receive the airflow layer 230. The notch 240 will be described in more detail with reference to Figures 5 to 7.

[0205] Figure 5 is an exploded view of the mattress system 200 of Figure 2 (displayed upside down), showing the top layer 202, the middle layer 204, and the airflow layer 230. The airflow pad assembly 232 may be positioned within a notch 240 of the middle layer 204. The airflow pad assembly 232 may be contained within the notch 240 and surrounded by the middle layer 204 so that the airflow pad assembly 232 is not exposed on the sides of the mattress system 200. In other words, the airflow pad assembly 232 is not visible from any side of the mattress system 200, while the middle layer 204 is visible from the sides of the mattress system 200, as shown in Figures 2 and 3. The airflow pad assembly 232 may be attached to the bottom surface 214 of the top layer 202 via the notch 240 of the middle layer 204. The airflow pad assembly 232 may be attached to the bottom surface 214 of the top layer 202 in various ways. For example, the airflow pad assembly 232 may be bonded to the bottom surface 214 of the top layer 202, or it may be attached to the bottom surface 214 of the top layer 202 using fasteners such as hook-and-loop fasteners (e.g., VELCRO®), zippers, clips, pins, buttons, straps, cords, snap fasteners, and other suitable types of fasteners.

[0206] Figures 6 and 7 are exploded views (upside down) of the mattress system 200 of Figure 2, showing the top layer 202, the middle layer 204, the rail structure 206, and one of the airflow pad assemblies 232. As shown, the rail structure 206 includes one or more notches 242, each notch 242 configured to receive an air duct 234 of the airflow pad assembly 232. The notches 242 can be sized to fully accommodate the air duct 234 so that the air duct 234 does not protrude from the inner surface of the rail structure 206. For example, the notches 242 can be sized to accommodate the air duct 234 so that it is flush with the inner surface of the rail structure 206 or positioned below (recessed) the level of the inner surface of the rail structure 206. Therefore, the air duct 234, which is received within the notch 242, does not interfere with other components of the mattress system 200, such as the air chamber 222, which is received within the space 210 of the rail structure 206. The notch 242 may be positioned in the rail structure 206 at a location corresponding to the position of the air duct 234 of the airflow pad assembly 232. In the illustrated example, the notch 242 is located within the rail structure 206 between the head and foot of the mattress system 200, such as in the middle of the length of the mattress system 200.

[0207] In an alternative embodiment, the mattress system 200 does not include a top layer 202. In this embodiment, the bottom layer 208 may function as the top layer of the mattress. Alternatively, the top layer 202 may have different sizes (e.g., thickness) to provide different levels of comfort or for other purposes.

[0208] In some implementations, the intermediate layer 204 may be positioned parallel to the airflow layer 230 (e.g., the air distribution layer). For example, the intermediate layer 204 may be configured to be parallel to the airflow pad assembly 232 when assembled.

[0209] [Airflow mattress with air chamber (feature group #1)] An exemplary arrangement of the components of the mattress 200 is described with reference to Figures 8A, 8B, and 9. Figure 8A is a cross-sectional view of the mattress system 200, including the top layer 202, the middle layer 204, the rail structure 206, the air chamber 222, the airflow layer 230, and the bottom layer 208, along line AA in Figure 2. An exemplary mattress cover 209 is shown in Figure 8A. Figure 8B is a cross-sectional view of the mattress system 200, including the top layer 202, the middle layer 204, the rail structure 206, and the airflow layer 230, along line BB in Figure 2. In Figure 8B, the air chamber 222 is schematically shown by a dashed line.

[0210] As described herein, the mattress 200 includes an inflatable air chamber 222, an airflow layer 230 (e.g., an air distribution layer), and a foam layer 203. The foam layer 203 may include a top layer 202. The foam layer 203 may further include an intermediate layer 204. The air distribution layer is positioned above the inflatable air chamber 222. The foam layer 203 is positioned above the air distribution layer and close to the top of the mattress. As described herein, the foam layer 203 and the air distribution layer (e.g., the airflow layer 230) may allow airflow through them. The air distribution layer does not resist airflow as much as the foam layer. For example, the air distribution layer may allow a higher amount of airflow than the foam layer above it. The mattress 200 further includes an air chamber hose (e.g., an air chamber hose 226) connected to the inflatable air chamber 222 for inflating or deflating the inflatable air chamber 222. For example, one end of the air chamber hose 226 is connected to the air chamber 222 so as to be in fluid communication with the inside of the air chamber 222, and the other end of the air chamber hose 226 is fluidly connected to a pump system (e.g., a pump system 224 as shown in Figures 10 and 19). The mattress 200 further includes an air distribution hose (e.g., an air duct 234) fluidly connected to the air distribution layer (e.g., an airflow layer 230) to move air in and out of the air distribution layer. In some implementations, in a bottom-to-top direction, the air distribution hose extends from a position below the inflatable air chamber, routes around the sides of the inflatable air chamber, and reaches the air distribution layer above the inflatable air chamber. In other words, in the reverse direction (from top to bottom), the air distribution hose is connected to the air distribution layer above the inflatable air chamber, routed around the sides of the inflatable air chamber, and extends below the lowest level of the inflatable air chamber so that the air distribution layer covers the lowest level of the inflatable air chamber.For example, as shown in Figure 8A, an air distribution hose (e.g., an air duct 234) is connected to an air distribution layer (e.g., an airflow layer 230) above the inflatable air chamber 222, and is then routed along the side of the air chamber 222, extending to a position lower than the inflatable air chamber 222.

[0211] In some implementations, the mattress 200 includes a mattress cover 209 that at least partially encompasses the components of the mattress 200, such as a top layer 202, an intermediate layer 204, a rail structure 206, an air chamber 222, an airflow layer 230, and a bottom layer 208. The mattress cover 209 includes a common opening 211 from which the air distribution hose and the air chamber hose can extend together.

[0212] In some implementations, the mattress 200 includes a plurality of inflatable air chambers, and the air distribution layer includes a plurality of air distribution zones or pads corresponding to the plurality of inflatable air chambers. In the illustrated example, the mattress 200 includes first and second air chambers 222A, 222B, and the air distribution layer includes two air distribution pads 232A, 232B (defining two air distribution zones) positioned below the first and second air chambers 222A, 222B, respectively, from the viewpoint of Figure 8A. The aforementioned air chamber hoses and air distribution hoses are similarly provided for each set of inflatable air chambers and air distribution pads.

[0213] In some implementations, the mattress 200 includes a chamber insulator 250 positioned between the first and second air chambers 222A, 222B and configured to reduce heat transfer between the first and second air chambers 222A, 222B. Additionally or alternatively, the mattress 200 includes an air distribution insulator 260 positioned between the first and second air distribution pads 232A, 232B and configured to reduce heat transfer between the first and second air distribution pads 232A, 232B. The chamber insulator 250 and the air distribution insulator 260 can reduce heat transfer between two different areas of the mattress 200 (e.g., left and right sides), thereby improving independent temperature control for different users resting on such different areas of the mattress top.

[0214] As shown in Figures 8B and 9 (bottom side view of mattress 200) and as described herein, the rail structure 206 includes a notch 242 (e.g., a hose passage) configured to receive and route an air distribution hose (e.g., an air duct 234). For example, the notch 242 is provided on the side rail of the rail structure 206. In some implementations, an air chamber hose (e.g., an air chamber hose 226) may be routed together with the air distribution hose within or adjacent to the notch 242.

[0215] In some implementations, a base (e.g., base 106) may be provided to support the mattress 200. For example, the base provides a support platform configured to support the mattress 200. The support platform may include a first base opening extending through the support platform and configured to receive an air chamber hose and / or an air distribution hose. A pump assembly (e.g., a pump assembly 224 as shown in Figures 10 and 19) may be fluidically connected to the hose end of the air chamber hose and configured to supply fluid (e.g., air) to an inflatable air chamber 222. The pump assembly may be positioned within the base. Furthermore, an air controller (e.g., an air controller 338 as shown in Figures 10 and 19) may be fluidically connected to the air distribution hose and configured to move air through the air distribution hose into or out of the air distribution layer. The air controller may be positioned within the base. An example of a base is further described herein with reference to, for example, Figures 17A, 17B, 18A, 18B, and 19.

[0216] Figure 10 shows a cross-sectional view of an exemplary mattress system 300. The mattress system 300 may be used to implement the mattress system 200 in Figures 2 to 9 or the mattress 104 in Figure 1. Similar to the mattress system 200, the mattress system 300 includes a top layer 302, an intermediate layer 304, a rail structure 306, an air chamber assembly 310, an airflow layer 330, and a bottom layer 308, which may be configured similarly to the top layer 202, intermediate layer 204, rail structure 206, air chamber assembly 220, airflow layer 230, and bottom layer 208, respectively.

[0217] Similar to the aforementioned airflow layer 230, the airflow layer 330 may include an airflow pad assembly 332. The airflow pad assembly 332 may include one or more airflow pads 334 and an air duct 336 extending from the airflow pads 334 and fluidly connecting the airflow pads 334 to an air controller 338. The air controller 338 is configured to control the temperature of the upper surface 312 of the top layer 302 by moving ambient air or regulated air through the airflow pads 334 and further through the top layer 302. For example, the air controller 338 may be operated to draw air from the airflow pads 334 and the top layer 302 through the air duct 336, thereby lowering the temperature of the upper surface 312 of the top layer 302. Alternatively, the air controller 338 may be operated to supply ambient air or cooling air to the airflow pad 334 via the air duct 336, thereby distributing such ambient air or cooling air over the top layer 302 and lowering the temperature of the top surface 312 of the top layer 302. Alternatively, the air controller 338 may be operated to supply heated air to the airflow pad 334 via the air duct 336, thereby distributing such heated air over the top layer 302 and raising the temperature of the top surface 312 of the top layer 302.

[0218] In the illustrated configuration, the air chamber hose 226 is routed to a side position on the mattress. In alternative configurations, the air chamber hose 226 may be routed (wired) to a different location on the mattress, such as the head or foot of the mattress, or another suitable location on the mattress.

[0219] In the illustrated configuration, the air duct 234 is positioned on the side of the mattress. In alternative configurations, the air duct 234 may be routed (wired) to other locations on the mattress. For example, at least one of the air ducts 234 may be located in the center of the mattress and extend between multiple air chambers 222 of the mattress.

[0220] [Airflow bat (feature group #2)] An exemplary airflow pad assembly 400 is illustrated with reference to Figures 11A to 11C, Figure 12, and Figure 13. Figures 11A to 11C are perspective views of an exemplary airflow pad assembly 400 used with a mattress system such as mattress 104, mattress system 200, or mattress system 300. The airflow pad assembly 400 may be used to mount the aforementioned airflow pad assemblies 232, 332.

[0221] Similar to the airflow pad assemblies 232 and 332, the airflow pad assembly 400 includes an airflow pad 402 and an air duct 404. The airflow pad 402 is positioned beneath the top layer of a mattress system, such as the top layers 202 and 302 of mattress systems 200 and 300. The airflow pad 402 is configured to allow air to flow through it and then through the top layer above it. In this example, the top layer of the mattress system may be manufactured from a foam that can be closed-cell, open-cell, or a combination thereof, so that air can be distributed through it. In some implementations, the airflow pad 402 is configured to allow a higher amount of airflow than the amount of airflow in the top layer above it.

[0222] The airflow pad 402 may allow ambient air or conditioned air to flow through it and further through the top layer above the airflow pad 402, thereby controlling the temperature of the top surface of the top layer (e.g., the surface opposite to the airflow pad 402). In some implementations, air may be drawn in from the airflow pad 402 and therefore from the top layer above the airflow pad 402, thereby lowering the temperature of the top surface of the top layer above the airflow pad 402. For example, when a user rests on the top surface of the top layer of a mattress system, drawing air in from the airflow pad 402 causes air to be drawn in further from the top layer, thereby cooling both the top layer and the user's body in contact with it. In other implementations, ambient air or cooled air may be supplied to the airflow pad and distributed to flow through the top layer above the airflow pad 402, thereby lowering the temperature of the top surface of the top layer above the airflow pad 402. In a similar example where the user rests on the top surface of the mattress system's top layer, supplying ambient or cooling air to the airflow pad 402 causes the air to be further distributed so that it enters and penetrates the top layer, thereby cooling the user's body in contact with the top layer. In yet another implementation, heated air may be supplied to the airflow pad and distributed so that it passes through the top layer above the airflow pad 402, thereby raising the temperature of the top surface of the top layer above the airflow pad 402. In a similar example where the user rests on the top surface of the mattress system's top layer, supplying heated air to the airflow pad 402 causes the air to be further distributed so that it enters and penetrates the top layer, thereby warming the user's body in contact with the top layer.

[0223] Referring to FIG. 13, the air flow pad 402 can include an air flow material 510 and a pad cover 412 that at least partially encloses the air flow material 510. The air flow material 510 can be a material different from the material of the top layer above the air flow pad 402. As described herein, the air flow material 510 is configured to provide a higher air flow rate than the air flow rate of the top layer above the air flow pad 402. Additionally, the air flow material 410 can be manufactured from a water-resistant material such that the air flow pad 402 can allow air distribution while avoiding water intrusion. Further, the air flow pad 402 can be manufactured to be breathable. Additionally, the air flow material 410 can be manufactured to be elastic enough to provide the desired support (force) for a user resting on the mattress system together with the other layers of the mattress system.

[0224] In some implementations, the airflow material 410 may have a three-dimensional structure having elastic polyolefin fibers. Additionally or alternatively, the airflow material 410 is manufactured from 100% polyolefin. Additionally or alternatively, the airflow material 410 is configured to provide an elastic modulus of over 95% of its thickness after 80,000 repeated compressions. Additionally or alternatively, the airflow material 410 includes Qshion® material, available from Qshion4D, Taiwan. Qshion® material provides a complex three-dimensional structure having elastic polyolefin fibers, which provides the desired ventilation and sleeping environment. Furthermore, Qshion® material includes POE material that is breathable, non-toxic, recyclable, and can provide full support and comfort. Qshion® material is washable and quick-drying. Qshion® material allows airflow to keep the user cool and comfortable for extended periods (e.g., overnight). Furthermore, Qshion® material is configured to help relieve (relax) pressure on the user's joints and muscles. Qshion® material is a non-toxic and recyclable material that allows the user to sleep in a safe and healthy environment. Qshion® material is more breathable than foam material. Furthermore, Qshion® material has a thickness modulus of 95% or more after 80,000 repeated compressions. Foam material, on the other hand, typically has a thickness modulus of 90% or less after the same repeated compressions. Qshion® material does not absorb moisture and is mite-free (does not breed house dust mites). Foam material, on the other hand, can retain moisture and breed mold. In other embodiments, the airflow material 410 may differ from Qshion® material in several respects but may include one, more, or all of the aforementioned properties of Qshion® material.

[0225] The pad cover 412 is configured to cover the air flow material 510. For example, the pad cover 412 is configured to at least partially enclose the air flow material 510. In some implementations, the pad cover 412 may include a zipper fastener 414 (FIG. 13) configured to open the pad cover 412 to receive or remove the air flow material 410. In other implementations, the pad cover 412 does not include a zipper fastener 414 or other fastener for reopening the pad cover.

[0226] As shown in FIGS. 11A and 12, the pad cover 412 may include a vent 416 configured to allow air to pass through. The vent 416 may be provided at the top of the pad cover 412 and may face the bottom surface of the top layer (e.g., bottom surfaces 214, 314 of top layers 202, 302) above the air flow pad 402. The pad cover 412 may be made of an air-restricting material such that air can flow at least substantially through the vent 416. The pad cover 412 may not have holes that significantly direct the air flow therethrough, except for the vent 416. Alternatively, the pad cover 412 may be made of a material that allows air flow at a slower rate than through the vent 416. In some implementations, the vent 416 is configured in the form of a window provided in the pad cover 412. In some implementations, the vent 416 is an opening covered with a mesh material. In other implementations, the vent 416 is an opening that may or may not have a material covering the opening. The vent 416 can be of various shapes, such as a square window, a rectangular window, a circular or oval window, and other suitable polygonal shapes. Additionally or alternatively, the vent 416 can be manufactured in the form of a plurality of holes and / or slits arranged in one or more groups.

[0227] In some implementations, the edges of the vent 416 may be spaced inward from the periphery of the airflow pad 402, forming a boundary around the vent 416. The boundary around the vent 416 can ensure that the surface (e.g., top surface) of the airflow pad 402 is not the vent 416 as a whole. For example, the vent 416 may be sized to have edges spaced by widths D1 to D4 from the periphery of the pad cover 412. The widths D1 to D4 may be sized such that the boundary around the vent 416 is wider on each side, resulting in less or no airflow closer to the outside of the airflow pad 402, and more airflow closer to the center and inside of the airflow pad 402. In some implementations, the inlet / outlet of the air duct 404 (e.g., the pad-side end 430) is located within a portion of the airflow pad 402 corresponding to (e.g., aligned with) the boundary around the vent 416. For example, the pad-side end 430 of the air duct 404 is located on the opposite side (back side) of the boundary (the portion having width D3) of the airflow pad 402. Such arrangement of the inlet / outlet of the air duct 404 can prevent airflow from being blown directly upward from the air duct 404 through the vent 416 in air supply mode, or from being directly drawn downward into the inlet / outlet of the air duct 404 through the bend 416 in air draw-in mode. Rather, such arrangement of the inlet / outlet of the air duct 404 can allow the air to be uniformly distributed through the entire (or most of) airflow material 410 as it flows between the inlet / outlet of the air duct 404 and the vent 416.

[0228] The pad cover 412 may be configured to provide a plenum chamber that substantially surrounds the core of the airflow material 510. For example, the pad cover 412 may be made of a material that restricts airflow while allowing air to flow through a vent 416. As shown in the figure, the airflow material 510 may be configured as a layer having a top, bottom, and sides. The pad cover 412 is positioned over at least a portion of the top, bottom, and sides of the airflow material 510 and provides an opening through a vent 416 positioned on the pad cover 412 that abuts against the top of the airflow material 410. The vent 416 may be covered with an airflow-permitting mesh material or other material so that air can flow through the vent 416 into and out of the airflow material 510 surrounded by the pad cover 412.

[0229] The airflow pad 402 is fluidically connected at one end to an air duct 404. The other end of the air duct 404 may be fluidly connected to an air controller (e.g., air controller 338) configured to supply ambient air or regulated air into the airflow pad 402 through the air duct 404, or to draw air from the airflow pad 402 through the air duct 404.

[0230] Referring to Figures 11A to 11C, the air duct 404 includes a pad-side end 430 that connects to the airflow pad 402 and is in fluid communication with the airflow material 410 within the airflow pad 402. The air duct 404 has a fan-side end 432 configured to be fluidly connected to a fan assembly (e.g., an air controller 338) or configured to engage (fit) with a connection point on a mattress base as shown in Figures 18A and 18B. In some implementations, the air duct 404 may be a bellows-style hose with a series of alternating flex points along the duct. This allows the air duct to expand and contract and bend to accommodate air controllers used in various applications.

[0231] As described herein, the airflow pad 402 may be configured to include various features that allow the airflow pad 402 to have a small form factor. For example, the airflow material 410 and pad cover 412 are configured to provide an airflow pad 402 that is thinner than the upper layer (e.g., top layer 202) of the airflow pad 402. For example, an intermediate layer 204 incorporating an airflow layer 206 (including one or more airflow pads 402) may be configured to be thinner than the top layer 202 so that the comfort that the top layer 202 can provide is not reduced or compromised by including the intermediate layer 204 and / or the airflow layer 206 (including the airflow pads 402). In some implementations, the ratio of the thickness of the top layer 202 to the intermediate layer 204 may be in the range of about 1.2 to about 10. For example, the top layer 202 may be manufactured to be 4 inches thick, and the intermediate layer 204 (including the airflow layer 206) may be manufactured to be 1 inch thick.

[0232] Referring to Figures 62 and 63, the air distribution layer may include two airflow pads 402 (including 402A and 402B) that can be connected together. For example, airflow pad 402A and airflow pad 402B are mechanically connected at interface 450. Various methods such as stitching, adhesive, fasteners, and other suitable mechanisms can be used to mechanically attach airflow pads 402A and 402B together at interface 450. The interconnected interface 450 between airflow pads 402A and 402B can prevent unstable positioning of airflow pads 402A and 402B (wobbling, misalignment, displacement, etc.) which may otherwise result from compression from the top of the mattress (e.g., due to body weight), user movement at the top of the mattress, or changes in air movement or pressure within the air chamber, etc. For example, while a user moves on the top of the mattress, one or both of the airflow pads 402A and 402B may wobble or be displaced or moved from their proper positions, which may result in separation between the airflow pads 402A and 402B. The interconnection at interface 450 can prevent such separation between the airflow pads 402A and 402B and keep them in place.

[0233] [Reinforcement strap (feature group #3)] An exemplary reinforcing strap 550 is described with reference to Figures 14 and 15. Figure 14 shows a bottom side perspective view of an exemplary mattress system 500 with a set of reinforcing straps 550 attached in place. Figure 15 shows a bottom side perspective view of the mattress system 500 with the reinforcing straps 550 removed.

[0234] One or more reinforcing straps 550 may be used to hold the mattress system 500 in place and prevent the mattress system 500 from bending outward during use. For example, the mattress system 500 may include one layer and a rail structure attached to the layer. The layer may have a top layer and a bottom layer opposite to the top layer. The layer may extend between a first layer edge and a second layer edge. Examples of the first and second layer edges are the side edges of the layer. Additionally, the layer may extend between a third layer edge and a fourth layer edge, examples of which are the head side edge and the foot side edge. The rail structure may include a first side rail attached to the bottom layer adjacent to the first layer edge and a second side rail attached to the bottom layer adjacent to the second layer edge. For example, the first and second side rails may be rails positioned on both sides along the length of the mattress. Furthermore, the rail structure may include a third side rail attached to the bottom of the layer adjacent to the edge of the third layer, and a fourth side rail attached to the bottom of the layer adjacent to the edge of the fourth layer. For example, the third and fourth side rails may be rails positioned at the head side edge and the foot side edge. One or more mattress cores, such as air chambers, foam, and / or spring assemblies, may be positioned below the bottom of the layer between the first and second side rails. Additionally, the core may be positioned below the bottom of the layer between the third and fourth side rails.

[0235] In the illustrated example, two reinforcing straps 550 may be used, including a first strap 550A and a second strap 550B. For example, the first strap 550A may be connected to a first side rail and a second side rail, and may extend below the core from the first side rail to the second side rail. One end of the first strap 550A may be connected to a first connection point located at the bottom of the first side rail, and the other end of the first strap 550A may be connected to a second connection point located at the bottom of the second side rail. Similarly, the second strap 550B may be connected to a first side rail and a second side rail, and may extend below the core from the first side rail to the second side rail. One end of the second strap 550B may be connected to a third connection point located at the bottom of the first side rail, and the other end of the second strap 550B may be connected to a fourth connection point located at the bottom of the second side rail. The first strap 550A and the second strap 550B may be arranged relative to each other in various configurations. For example, the first strap 550A may be positioned near the second strap 550B and may extend parallel to the second strap 550B. The first strap 550A may be positioned at a certain distance from the second strap 550B which extends parallel to the first strap 550A. An example of such distance may be in the range of about 5 inches to about 70 inches. Although two reinforcing straps are primarily shown in the illustrated example, more than two reinforcing straps 550 may be used in a similar manner in other implementation configurations. Furthermore, in alternative implementation configurations, a single reinforcing strap 550 may be used in the desired configuration.

[0236] As shown in Figures 14 and 15, the mattress system 500 may be configured similarly to mattress 104 or mattress systems 200, 300. For example, the mattress system 500 may include a top layer 502, an intermediate layer 504, a rail structure 506, and an airflow layer 530, which may be configured similarly to top layers 202, 302, intermediate layers 204, 304, rail structures 206, 306, and airflow layers 230, 330, respectively. The mattress system 500 may be configured to include various types of cores, such as one or more inflatable air chambers, foam, and / or spring assemblies, which may be housed in the space defined by the rail structure 506 in the same or similar manner as described above.

[0237] The rail structure 506 may include a head rail 562, a foot rail 564, and side rails 566, 568 extending between the head rail 562 and the foot rail 564. In some implementations, the rail structure 506 may be manufactured from one or more foam materials. In this example, the rail structure 506 is attached to the intermediate layer 504. When attached to the intermediate layer 504, the rail structure 506 may also engage with or be attached to an airflow layer 530 positioned within a notch in the intermediate layer 504 (for example, flush with the intermediate layer 504). For example, the head rail 562 is attached to the bottom of the intermediate layer 504 at (or near) the head edge of the intermediate layer 504, and the foot rail 565 is attached to the bottom of the intermediate layer 504 at (or near) the foot edge of the intermediate layer 504 (opposite the head edge of the intermediate layer 504). The side rails 566, 568 are attached to the bottom of the intermediate layer 504 on both sides of the intermediate layer 504 (or adjacent to it). Similar to the rail structures 206, 306, the rail structure 506, together with the multiple layers (e.g., the intermediate layer 504, the airflow layer 530 and / or the top layer 502), forms an inverted foam tab. For example, the rail structure 506 defines a space for receiving a mattress core 520, such as one or more inflatable air chambers, foam and / or spring assemblies.

[0238] The reinforcing strap 550 may include a first strap 550A. The first strap 550A may be connected to the side rails 566, 568 so as to extend beneath the mattress core 520 between the bottoms of the side rails 566, 568. The first strap 550A may be attached to the side rails 566, 568 at predetermined connection positions 570A, 572A. Furthermore, the reinforcing strap 550 may include a second strap 550B. Similar to the first strap 550A, the second strap 550B may be connected to the side rails 566, 568 so as to extend beneath the mattress core 520 between the bottoms of the side rails 566, 568. The second strap 550B may be attached to the side rails 566, 568 at predetermined connection positions 570B, 572B. In some implementations, the first strap 550A and the second strap 550B are positioned in the central longitudinal portion of the mattress. The first strap 550A may extend parallel to the second strap 550B and may be spaced a predetermined distance from the second strap 550B.

[0239] Other configurations of the strap 550 may also be possible. In some implementations, the straps 550 may be routed to intersect each other. For example, the first strap 550A and the second strap 550B may be connected to the side rails 566, 568 and extend under the mattress core 520 between the bottoms of the side rails 566, 568. The first strap 550A may be routed to intersect the second strap 550B by connecting one end of the first strap 550A to one of the side rails 566, 568 between the head rail 562 and the second strap 550B, and connecting the other end of the first strap 550B to the other side rail 566, 568 between the foot rail 562 and the second strap 550B. An example of intersecting routing of the straps 550 is shown in Figure 16.

[0240] In other embodiments, one or more straps 550 may extend to one or both of the head rail 562 and the foot rail 564. In one example, one or more straps 550 may extend from the head rail 562 to the foot rail 564, rather than extending between the side rails 566, 568. In another example, in addition to having one or more straps 550 extending between the side rails 566, 568, one or more (further) straps 550 may extend from the head rail 562 to the foot rail 564.

[0241] In some implementations, the rail structure 506 may include one or more notches for various purposes. For example, the rail structure 506 may include a notch 542 configured to receive an air duct of the airflow pad assembly 530 and / or other components of the mattress system (e.g., air passages, electronic wiring, etc.). The notch 542 may be configured similarly to the notch 242 described herein. The notch 542 of the rail structure 506 may structurally weaken the rail structure 506 in or around the notch. A strap 550 may be attached to the rail structure 506 on the opposite side of the notch 542, thereby reinforcing or maintaining the rail structure 506 in or around the notch 542. For example, in the illustrated example, the notch 542 is provided within the side rails 566, 568, and the first strap 550A and / or the second strap 550B are connected to the side rails 566, 568 adjacent to the notch 542, as shown in Figures 14 and 15.

[0242] The strap 550 can be attached to the rail structure 506 using one or more fastening elements 574. The fastening elements 574 can be of various types. For example, the fastening elements 574 include adhesive tape. Alternatively or additionally, the fastening elements 574 may be hook-and-loop fasteners (e.g., VELCRO®), zippers, clips, pins, buttons, straps, cords, snap fasteners, and other suitable types of fasteners. The fastening elements 574 may be applied at connection points 570A, 570B, 572A, 572B, or at desired locations on the strap 550 (e.g., ends), so that such desired locations on the strap 550 can be attached to the connection points of the rail structure 506. For example, adhesive tape may be applied between the connection points 570A, 570B, 572A, 572B of the rail structure and the ends of the strap 550.

[0243] As shown in Figure 14, the mattress system 500 may further include a mattress cover 580 configured to cover the components of the mattress system 500, such as a top layer 502, an intermediate layer 504, a rail structure 506, a mattress core 520, an airflow layer 530, and straps 550.

[0244] Thus, reinforcing straps extending between rails and crossing the bottom of the mattress can help hold the mattress core and other mattress components in place, and can help prevent them from bending outward after repeated peripheral stress on the bed caused by user entry and exit. Reinforcing straps can be used with multiple hook material pieces (e.g., 3M hook material) having an adhesive backing. The hook material can be positioned along the bottom side of the peripheral side rails. In some implementations, the reinforcing straps may include scrim material, which can be attached to the hook material and extend from one side of the bed to the other. The straps may be removable and allow for assembly without interference from other components (e.g., air chambers, multiple layers, etc.). The straps may be adjustable to accommodate stretching and changes over time, tolerances for changes in foam tabs and their covers, or the influence of general aesthetic preferences. The straps may have widths of various sizes, such as in the range of approximately 1 inch to 7 inches.

[0245] [Connection interface between mattress and base (feature group #4)] Referencing Figures 17 to 20, exemplary connection interfaces for connecting a mattress to a base are described. Generally, a mattress has a mattress top and a mattress bottom opposite the mattress top, with the mattress interior defined between the mattress top and mattress bottom. When the mattress is placed on a base, the user can rest on or above the mattress top. In some implementations, the mattress has a first connection portion positioned on the mattress bottom, defining a first air hole configured to allow airflow through the first connection portion. The mattress may include an air hose extending from the first air hole in the first connection portion into the mattress interior. For example, as shown in Figures 18A and 18B, mattress 600 is configured to provide a first connection portion 652 at the bottom of the mattress. The first connection portion 652 is in fluid communication with an internal hole 654 located inside the mattress 600. The internal hole 654 may be provided for multiple purposes. In one example, the internal hole 654 is an air hole that allows air to flow into or out of an air-fillable or air-distributing component, such as an inflatable air chamber (e.g., air chamber 222) and / or an airflow layer (e.g., airflow layers 230, 330, 530). Alternatively or additionally, the internal hole 654 may be a hole that allows other elements, such as wires or cables, to pass through. The mattress 600 may further include a duct (or hose) 656 extending from the internal hole 654 inside the mattress 600 and extending from the bottom of the mattress through a first connection portion 652. In some implementations, the duct 656 may be an air hose or air duct configured to be similar to the air ducts 234, 336, 404. The duct 656 may be made of a flexible material. The duct 656 may have a mating end 658 configured to engage with a second connecting portion 672 provided within the base 670. As described below, the mating end 658 may be made of a flexible material and may snap-fit ​​to the second connecting portion 672.

[0246] The base 670 is sized and configured to be positioned under the bottom of the mattress 600 and support the mattress 600 on the support surface 673. The base 670 includes a second connection portion 672 positioned on the support surface 673. The second connection portion 672 defines interface holes 676 for one or more purposes. For example, the interface holes 676 are air holes configured to allow air to flow through the second connection portion 672. Alternatively or additionally, the interface holes 676 can be holes that allow other elements, such as wires or cables, to pass through. The second connection portion 672 can be arranged to be aligned with the first connection portion 652 when the mattress 600 is positioned on the base 670. The second connection portion 672 can be configured to be connected to the first connection portion 652. For example, the second connection portion 672 is configured to couple to the mating end 658 of the duct 656 at or adjacent to the first connection portion 652 such that the second connection portion 672 is directly or indirectly engaged with the first connection portion 652. When the first connection portion 652 is coupled to the second connection portion 672, the internal holes 654 (e.g., air holes) within the mattress 600 are fluidly connected to the interface holes 676 (e.g., air holes) within the base 670, and air can flow between the base and the mattress through the internal holes 654 and the interface holes 676. In some implementations, the internal holes 654 (e.g., air holes) within the mattress 600 can be configured to be aligned with the interface holes 676 (e.g., air holes) within the base 670.

[0247] In some implementations, the duct 656 extending from the mattress 600 is sized and shaped to snap-fit ​​to a second connection portion 672 of the base 670. For example, the second connection portion 672 may include a base 680 and a lip 682 projecting from the base 680 and defining an interface hole 676 around it. The second connection portion 672 may further include a fitting flange 684 extending radially outward at the upper end of the lip 682, as shown in Figure 17B, which is a partial cross-sectional view along line AA in Figure 17A. As shown in Figure 18B, the fitting end 658 of the duct 656 may include a gripping portion 670 that allows a user (e.g., installer or customer) to grasp the fitting end 658 of the duct 656 in order to carry it onto the second connection portion 672. The mating end 658 may be manufactured to be flexible so as to bend to allow it to cover the lip 682 of the second connecting portion 672. As the mating end 658 slides over the lip 682, the mating flange 684 engages with the mating end 658 so that it fits onto the lip 682. In some configurations, the mating end 658 of the duct 656 may include a groove corresponding to the mating flange 684, thereby securing the mating end 658 to the lip 682 of the second connecting portion 672.

[0248] Mattress 600 may be configured similarly to mattress 104 or mattress systems 200, 300, 500, and may include one or more components similar to top layers 202, 302, 502, intermediate layers 204, 304, 504, rail structures 206, 306, 506, and / or airflow layers 230, 330, 530. Mattress system 600 may be configured to include one or more inflatable air chambers, foam and / or various types of cores such as spring assemblies. These may be housed within spaces defined by rail structures in the same or similar manner as described herein. For example, duct 656 of mattress 600 may be configured to fluidly connect to the airflow layers of mattress 600 (similar to airflow layers 230, 330, 530), and may be configured similarly to air ducts 234, 336, 404.

[0249] In embodiments in which the mattress 600 includes a plurality of first connecting portions 652, a plurality of second connecting portions 672 may be provided. For example, in embodiments in which two airflow layers (and thus two first connecting portions 652) are provided within the mattress 600 (as described herein with respect to mattresses 200 and 300), two second connecting portions 672 may be provided corresponding to the first connecting portions 652.

[0250] The base 670 may be an adjustable base. For example, the base 670 may be configured to raise or lower the head of a mattress 600 supported on the base 670. Additionally or alternatively, the base 670 may be configured to raise or lower the foot of a mattress 600 supported on the base 670. As shown in Figure 19, the base 670 may include a head panel 690, a foot panel 692, and one or more intermediate panels 694A, 694B between the head panel 690 and the foot panel 692. The head panel 690 is configured to raise or lower the head of the mattress 600, and the foot panel 692 is configured to raise or lower the foot of the mattress 600. The central panel 694A is configured to maintain a substantially stationary position when one or both of the head panel 690 and the foot panel 692 are articulated. The central panel 694B is configured to connect the central panel 694A to the foot panel 692, and as a result, it can also move up and down when the foot panel 692 moves up and down. In some implementations, a second connection portion 672 is located on the central panel 694A of the base 670. The second connection portion 672 may be fluidly connected to an air controller 338 mounted on the bottom of the base 670. In some implementations, the base 670 further includes one or more air chamber interface conduits 696 configured to allow components of an air chamber assembly (e.g., air hoses, wires, etc.) to pass through and connect to a pump assembly 224 which may be mounted on the bottom of the base 670. The air chamber interface conduits 696 may also be located within the central panel 694A.

[0251] In some implementations, all panels of the base 670, including the central panel 694A, may be configured to rise or fall. In some implementations, the base 670 may contain more or fewer than four panels, such as having only three panels (e.g., head, middle, and foot), or having five or more panels.

[0252] The connection interface between the aforementioned first connection port 652 and the second connection portion 672 (e.g., mating with the second connection portion 672 of the duct 656) can provide sufficient strength to hold the mattress 600 to the base 670 when the base 670 is articulated to raise and lower the head and / or foot portions of the mattress 600. In some implementations, the connection between the first connection port 652 and the second connection portion 672 (e.g., mating with the second connection portion 672 of the duct 656) is solely the connection mechanism between the mattress 600 and the base 670, without additional connectors such as adhesives, hook-and-loop fasteners (e.g., VELCRO®), zippers, clips, pins, buttons, straps, cords, snap fasteners, and other suitable types of fasteners.

[0253] Referring again to Figure 17A, the second connection portion 672 may include a duct support rib 674 extending from the base 680. The duct support rib 674 may be sized and shaped so that it extends upward within the duct 656 at the mating end 658 when the mating end 658 of the duct 656 is mated with the second connection portion 672. The duct support rib 674 is configured to provide structural rigidity to the duct 656 when the duct 656 is connected to the second connection portion 672. For example, the duct support rib 674 may have a width W similar to the corresponding inner width W of the duct 656 and a height H from the base 680 so that the shape (e.g., width) of the duct 656 can be maintained along at least the height H when the duct 656 is mated with the second connection portion 672.

[0254] The duct support rib 674 may be sized and shaped to provide adequate support (force) to the duct 656 with little or no restriction of airflow. For example, the duct support rib 674 may have first and second side walls 674A, 674B extending upward from opposite sides of the interface hole 676, and a crossing wall 674C extending substantially across the interface hole 676 from side wall 674A to side wall 674B. The crossing wall 674C may have a relatively thin cross section to relatively minimize restriction of flow into or out of the interface hole 676.

[0255] Figures 20A to 20C show an exemplary mattress coupling assembly 640. In some implementations, the mattress coupling assembly 640 includes a first coupling element 642 and a second coupling element 644. The first coupling element 642 may be positioned on the bottom of the mattress 600, around an air duct 656 extending from the bottom of the mattress. For example, the first coupling element 642 may be positioned on the outer surface of a mattress cover or other sheet that encloses the bottom of the mattress 600. Additionally, the second coupling element 644 may be positioned on the inner surface of the mattress cover or other sheet, and may be positioned around the air duct 656 such that the second coupling element 644 is aligned with the first coupling element 642, with the mattress cover or other sheet between them. The first coupling element 642 is configured to snap-fit ​​with the second coupling element 644, with a mattress cover or other sheet between them, the first coupling element 642 being exposed at the bottom of the mattress (outside the mattress cover or sheet), and the second coupling element 644 being positioned at least partially inside the mattress and at least partially hidden from the outside of the mattress bottom. The first coupling element 642 is configured to fit into a corresponding connecting portion, such as a second connecting portion 672 (of various forms), provided on the base 670. For example, the first coupling element 642 may slide into and couple with the connecting portion of the base 670. In other examples, the first coupling element 642 may snap-fit ​​with the connecting portion of the base 670.

[0256] In some implementations, the first coupling element 642 may include one or more protruding clips configured to extend downward into and engage with a connection portion of the base (e.g., a second connection portion 672) for coupling the mattress to the base. In alternative implementations, the second coupling element 644 may include one or more protruding clips configured to extend downward into and engage with a connection portion of the base (e.g., a second connection portion 672) for coupling the mattress to the base. In even more alternative implementations, both the first coupling element 642 and the second coupling element 644 may include one or more protruding clips configured to extend downward into and engage with a connection portion of the base (e.g., a second connection portion 672) for coupling the mattress to the base.

[0257] Figure 20D shows another exemplary mattress coupling assembly 650. Similar to the mattress coupling assembly 640 shown in Figures 20A to 20C, the mattress coupling assembly 650 includes a first coupling element 652 and a second coupling element 654. The first coupling element 652 may be positioned on the bottom of the mattress 600, around an air duct 656 extending from the bottom of the mattress. For example, the first coupling element 652 may be positioned on the outer surface of a mattress cover or other sheet that encloses the bottom of the mattress 600. Additionally, the second coupling element 654 may be positioned on the inner surface of the mattress cover or other sheet, and may be positioned around the air duct 656 such that the second coupling element 654 aligns with the first coupling element 652, with the mattress cover or other sheet between them. The first coupling element 652 may be connected to the second coupling element 654 by one or more fasteners 660, while a mattress cover or other sheet may be engaged between the first coupling element 652 and the second coupling element 654. Other connecting mechanisms such as snap-fit ​​couplings, interlocking fits, adhesives, latches, etc., may be used to connect the first coupling element 652 to the second coupling element 654. When assembled, the first coupling element 652 is exposed at the bottom of the mattress (outside the mattress cover or sheet), while the second coupling element 654 is positioned at least partially inside the mattress and at least partially hidden from the outside of the mattress bottom. The first coupling element 662 is configured to fit into a corresponding connecting portion 656 (e.g., a second connecting portion 672) provided on the base 670. The connecting portion 656 may be fixed around an air passage in the base 670. In some implementations, the first coupling element 652 includes a hook or clip 662 configured to removably engage with the inner circumference of the connecting portion 656. In some implementations, the connecting portion 656 may include a portion (e.g., a recess) for removably locking the hook or clip 662 of the first coupling element 652.

[0258] The mattress coupling assembly 650 may further include a removal tool 658 configured to easily unlock the mattress from the base. For example, the removal tool 658 may slide under the coupling portion 656 to push inward the hook or clip 662 of the first coupling element 652, thereby disengaging the hook or clip 662 of the first coupling element 652 from the coupling portion 656, and removing the mattress from the base 670.

[0259] Figure 65 shows another example of a second connecting portion 672 for connecting to a first connecting portion 652 of the mattress 600. In this example, the second connecting portion 672 is constructed similarly to the second connecting portion 672 in Figure 17A, but with some modifications. For example, the second connecting portion 672 in Figure 65 does not include a duct support rib 674. Instead, the second connecting portion 672 has an extension lip 682 extending from the base 680, the lip 682 which may provide reinforcement for an air duct that fits above the second connecting portion 672. As illustrated, the lip 682 in Figure 65 is longer than the lip 682 in Figure 17A. In an alternative embodiment, the extension lip 682 may be provided together with the duct support rib 674.

[0260] In some implementations, the connection interface may include a mechanism for mechanically connecting the mattress to the base, which can be used independently or in combination with other types of connection interfaces described herein. For example, the connection mechanism may include one or more magnets positioned at the bottom of the mattress and the corresponding top of the base, so that when the magnets of the mattress are engaged with the corresponding magnets of the base, the mattress can be fixed in place relative to the base. The mattress can remain in place relative to the base unless a force exceeding a threshold is applied to the magnetic connection. Additionally or alternatively, the connection mechanism may include one or more hooks, clips, buttons, or other suitable locking means. For example, the mattress may include a set of hooks around its sides, bottom, and / or other suitable areas, and the base may include pieces (e.g., rings, holes, hooks, clips, buttons, etc.) into which the hooks or clips engage. These pieces (parts) may be positioned around the sides, top, and / or bottom of the base to correspond to the positions of the hooks on the mattress. The mattress can be attached to or locked onto the base by engaging the mattress hooks with the corresponding pieces of the base.

[0261] Referring to Figure 64, the air duct 404 may be directly attached to the pad cover 412 (e.g., the envelope). For example, the pad-side end 430 of the air duct 404 may be secured to the pad cover 412 by stitching 452. Other fastening methods may also be used to directly secure the pad-side end 430 to the pad cover 412.

[0262] In some implementations, the air duct 404 may include one or more ribs 454 configured to maintain the passage width 456 of the air duct 404. As shown in Figure 64, the air duct 404 may include two opposing ribs 454 located on a wider, opposing inner surface of the air duct 404 and positioned in the center of the wider inner surface of the air duct 404. In embodiments in which the air duct 404 is manufactured to be flexible, the air duct 404 may be compressed or bent to block the passage of the air duct 404. The ribs 454 are configured to reinforce the air duct 404 while allowing flexibility in the air duct 404. When the air duct 404 is compressed from one or both of the wider, opposing sides, the ribs 454 may come into contact with each other to resist such compression, thereby ensuring the air passage through the air duct 404.

[0263] In some implementations, the ribs 454 may be positioned along the entire length of the air duct 404. The ribs 454 may be arranged continuously along the entire length of the air duct 404. Alternatively, multiple sets of ribs 454 may be positioned at intervals along the entire length of the air duct 404. Alternatively, the ribs 454 may be positioned along a portion of the length of the air duct 404. For example, the ribs 454 may be positioned adjacent to the fan-side end 432 of the air duct 404. In other examples, the ribs 454 may be positioned along their length in the middle of the air duct 404, or near the pad-side end 430.

[0264] [Air Controller Assembly (Feature Group #5)] An exemplary air controller 700, used with mattress 104 or mattress systems such as mattress systems 200, 300, 500, 600, etc., is described with reference to Figures 21 to 26. For example, air controller 700 may be used to implement air controller 338 in Figures 10 and 19. Air controller 700 is configured to move air into or out of airflow layers (e.g., airflow layers 230, 330, 530) within the mattress system. For example, air controller 700 may be configured to draw air from the airflow layers of the mattress and / or to supply ambient air or conditioned air to the airflow layers. Additionally, air controller 700 may conditioned the air before supplying it to the airflow layers. For example, air controller 700 may be operated to heat or cool the air and then introduce the heated or cooled air into the airflow layers.

[0265] Referring to Figure 21, the air controller 700 includes a housing 702 having a connection side (e.g., mattress side) 704 and a perimeter side 706. The connection side 704 of the housing 702 is configured to be mounted at a desired location, such as the underside of a base supporting a mattress. The housing 702 includes a connection side opening (e.g., mattress side opening) 708 on the connection side 704 and a perimeter side opening 710 on the perimeter side 706. In embodiments in which the air controller 700 is used with the base 670 described herein, the housing 702 may be mounted on the base 670 by the connection side 704 such that the connection side opening 708 is in fluid communication with the interface hole 676 of the second connection portion 672 of the base 670 and in fluid communication with the internal hole 654 of the mattress 600 when the mattress 600 is supported on the base 670 and a duct 656 from the mattress 600 is coupled to the second connection portion 672 of the base 670. The periphery side 706 of the housing 702 may be exposed to the atmosphere, and air may be drawn in from the surroundings through the periphery opening 710 or discharged to the surroundings.

[0266] Referring to Figures 22A and 22B, the air controller 700 may include a fan assembly 714 mounted within the housing 702 and configured to allow air to flow through the housing 702. In some implementations, the fan assembly 714 is configured as a reversible fan assembly configured to allow air to flow in opposing directions. For example, the fan assembly 714 may be operated to rotate the fan in one direction to allow air to flow from the periphery side 706 to the connection side 704 of the housing 702. Furthermore, the fan assembly 714 may be operated to rotate the fan in the opposite direction to allow air to flow from the connection side 704 to the periphery side 706 of the housing 702. In some implementations, the fan assembly 714 is positioned on the periphery side 706 of the housing 702, as shown in Figures 22A and 22B. Other positions of the fan assembly 714 are possible in other implementations. For example, the fan assembly 714 may be positioned adjacent to the heating element 716, such as between the heating element 716 and the PCB board (e.g., the control unit 718).

[0267] The air controller 700 may include a heating element 716 mounted within the housing 702 and configured to heat the air passing through the heating element 716. In some implementations, the heating element 716 includes a plurality of fins that allow the airflow between the fins to be heated by the heating element. As described herein, the heating element 716 may be mounted within the housing 702 at a position at least partially spaced from the inner wall of the housing 702, such as defining a bypass flow path that allows air to flow around the heating element 716 while air is simultaneously flowing through the heating element 716. Such a bypass flow path may allow for effective airflow through the housing when air is drawn from the mattress and flows from the connecting opening 708 to the periphery opening 710, or when air is supplied and flows from the periphery opening 710 toward the connecting opening 708, with or without the heating element 716 activated.

[0268] The air controller 700 may include a control unit 718 mounted within the housing 702 and configured to control the air controller 700 in one or more operating modes. For example, the control unit 718 may operate the air controller 700 in a first mode (ambient air draw-in mode) in which the control unit 718 controls the fan assembly 714 so that air flows from the connection side 704 to the periphery side 706 and air is drawn in from the airflow layer of the mattress. Alternatively or additionally, the control unit 718 may operate the air controller 700 in a second mode (heated air supply mode) in which the control unit 718 activates the heating element 716 and controls the fan assembly 714 so that air flows from the periphery side 706 to the connection side 704 so that the air flows through the heating element 716 and heated air is supplied to the airflow layer of the mattress. Alternatively or additionally, the control unit 718 may operate the air controller 700 in a third mode (ambient air supply mode) in which the control unit 718 controls the fan assembly 714 (without activating the heating element 716) so that air flows from the ambient side 706 to the connection side 704 and ambient air is supplied to the airflow layer of the mattress.

[0269] In an alternative embodiment, the air controller 700 may include a cooling unit with or without the heating element 716, and the air controller 700 may be operated in additional operating modes. For example, the control unit 718 may operate the air controller 700 in a fourth mode (cooling air supply mode) in which the control unit 718 activates the cooling element and controls the fan assembly 714 so that air flows from the ambient side 706 to the connection side 704, and the air flows through the cooling element and the cooled air is supplied to the airflow layer of the mattress.

[0270] The air controller 700 may consist of a printed circuit board. The printed circuit board may be positioned within the housing 702 between the peripheral opening 710 and the heating element 716. The fan assembly 714 may be positioned within the housing 702 between the peripheral opening 710 and the heating element 716. The air controller 700 may be electrically connected to the fan assembly 714 and the heating element 716 to control the operation of the fan assembly 714 and the heating element 716.

[0271] The air controller 700 may include one or more temperature sensors configured to detect temperatures at different locations. For example, the air controller 700 may include a first temperature sensor 720 configured to detect the temperature of a heating element 716 and generate a sensor signal 730 representing the temperature of the heating element 716. The air controller 700 may include a second temperature sensor 722 configured to detect the outlet temperature of air leaving the housing 702, such as the temperature of air present on the connection side 704, and generate a sensor signal 732 representing the outlet temperature. The control unit 718 may receive sensor signals 730, 732 from the first and second temperature sensors 720, 722 to achieve a predetermined outlet air temperature and may control the heating element 716 based at least in part on the sensor signals 730, 732. For example, the control unit 718 may determine an offset value of the detected outlet air temperature from a predetermined outlet air temperature and may control the heating element 716 to compensate for the offset value so that the outlet air temperature reaches the predetermined outlet air temperature.

[0272] The second temperature sensor 722 may be used, for example, to detect the temperature of air drawn into the housing 702 from the airflow layer of a mattress and to generate a sensor signal 732 representing the temperature of the drawn-in air. Alternatively, the air controller 700 may include a separate temperature sensor (e.g., a third temperature sensor) for detecting the temperature of the drawn-in air. The air controller 700 may further include a fourth temperature sensor 724 configured to detect the ambient temperature and generate a sensor signal 734 representing the ambient temperature. The control unit 718 may receive sensor signals 732, 734 from the second (or third) and fourth temperature sensors 722, 724 to achieve a predetermined drawn-in air temperature and may control the fan assembly 714 at least in part on the sensor signals 732, 734. For example, the control unit 718 may determine an offset value of the detected drawn-in air temperature from a predetermined drawn-in air temperature and may control the fan assembly 714 to compensate for the offset value so that the drawn-in air temperature reaches the predetermined drawn-in air temperature. Additionally, the control unit 718 can calculate the amount of heat extracted from the airflow layer of the mattress based on the sensor signals 732 and 734.

[0273] Additionally, the air controller 700 may include one or more humidity sensors 726 configured to detect a humidity value and generate a sensor signal 736 representing that humidity value. The control unit 718 may receive the sensor signal 736 and control the fan assembly 714 and / or heating element 716 based in part on the sensor signal 736 to achieve a predetermined humidity value. For example, the control unit 718 may determine an offset value of the detected humidity value from a predetermined humidity value and control the fan assembly 714 and / or heating element 716 to compensate for the offset value so that the humidity reaches the predetermined humidity value.

[0274] Referring again to Figures 22 and 23, the housing 702 includes a curved conduit 750 between the connecting side 704 and the surrounding side 706. In some implementations, the heating element 716 is positioned in the curved conduit 750. The heating element 716 may be sized to be smaller than the cross-section of the curved conduit 750. For example, as shown in Figure 24, the primary region of the heating element 716 is smaller than the cross-section of the curved conduit 750 to open up the region surrounding the heating element 716, thereby allowing interference-free airflow. In some implementations, the housing 702 includes opposing spacers 754 that extend from the inner surface of the housing 702 and are configured to crimp the heating element 716 between them. In some implementations, as shown in Figures 22A and 22B, the heating element 716 may be positioned closer to the outer corner 752A of the curved conduit 750 than to the inner corner 752B of the curved conduit 750. In some implementations, the housing 702 may include one or more vanes 755 (Figure 24) configured to direct the airflow that bypasses the heating element 716.

[0275] As shown in Figures 22A and 22B, the fan assembly 714 may be positioned in the periphery opening 710 of the housing 702. In some implementations, as shown in Figure 25, the housing 702 includes ribs 756 configured to extend from the inner surface of the housing 702 and engage with the fan assembly 714 at the periphery 706 to secure the fan assembly 714 to the periphery opening 710 of the housing 702. Furthermore, the air controller 700 may include foam material 758 positioned between the fan assembly 714 and the ribs 756 of the periphery opening 710. Together with the ribs 756, the foam material 758 can secure the fan assembly 714 to the periphery opening 710 of the housing 702 and can also absorb vibrations of the fan assembly 714, so that these vibrations are not transmitted to the housing 702 and the rest of the bed (e.g., the base and mattress).

[0276] The air controller 700 may include one or more air screens. For example, as shown in Figures 21 and 22, the air controller 700 may include a first screen 760 located at the connecting side opening 708 of the housing 702. As shown in Figure 26, the air controller 700 may include a second screen 762 located at the periphery side opening 710 of the housing 702. The first and second screens 760, 762 are configured to filter debris, dirt, and contaminants from the air passing through the air controller 700, thereby preventing them from entering the air controller 700 and / or the mattress to which the air controller 700 is coupled.

[0277] Referring to Figure 22B, the air controller 700 may include one or more air deflectors 770 configured to improve the distribution of regulated air to the mattress. The air deflectors 770 may be positioned at various locations along one or more airflow paths through the air controller 700. For example, the air deflectors 770 may be positioned around a heating element 716 to restrict airflow in one direction and promote airflow in the opposite direction. In the illustrated example, the air deflectors 770 are positioned in the airflow path around the heating element 716 and are configured to open the airflow path around the heating element 716 when air is drawn in from the mattress. The open airflow path around the heating element 716 may promote airflow into the air controller 700 by routing all or most of the air around the heating element 716 and reducing or eliminating the air passing through the heating element 716. In contrast, when the air controller 700 is activated to supply heated air to the mattress, the air deflector 770 is configured to prevent airflow around the heating element 716 so that the air flows through the heating element 716 and is heated before it is discharged from the heating element 716.

[0278] In some implementations, the air deflector 770 may be manufactured from at least partially flexible material so as to bend and open or close depending on the direction of the airflow. Alternatively or additionally, the air deflector 770 may be hinged to the structure of the air controller 700 so as to hinge open when air flows in one direction and hinge close when air flows in the other direction. In some implementations, the air controller 700 may include a stopper 7772 configured to engage with a portion of the air deflector 770 (e.g., the free end) to close the air passage and prevent airflow along the air passage.

[0279] [Exemplary system involving air and foot warming (feature group #1)] Referring to Figures 27 to 30, an exemplary foot warming system that may be used for mattress 104 or mattress systems 200, 300, 500, 600, etc., is described. The foot warming system may be used in conjunction with airflow layers within the mattress, such as airflow layers 230, 330, 530, etc., as described herein. For example, the foot warming system may be positioned within the mattress to provide heating to the foot area of ​​the mattress, and the airflow layer may be positioned within the mattress to provide cooling or heating within a given area of ​​the mattress (e.g., the middle area and / or the head area). Separate control systems may be provided for the foot warming system and the airflow layer for independent operation. Alternatively, a single control system may be connected to both the foot warming system and the airflow layer, while it may control them independently. In some implementations, the operation of the foot warming system and the airflow layer may be coordinated to provide a desired effect to a user resting on the mattress.

[0280] Figure 27 is a perspective view of an exemplary bed 800 having a foot warming system 802. The bed 800 may comprise a base 804 and a mattress 806 supported by the base 804. In some embodiments, the bed 800 may be an airbed system, such as the airbed system 100 shown in Figure 1, and may have one, more, or all of the features described above with respect to Figures 1 to 26. In other embodiments, the bed 800 may be another type of bed suitable for the application, such as a bed having foam and / or springs without an inflatable air chamber. In some embodiments, the base 804 may be an articulated base. In other embodiments, the base 804 does not need to be articulated. In some embodiments, the bed 800 does not need to include any base.

[0281] In the embodiment shown in Figure 27, the mattress 806 includes a support structure 808 and a cover 810 configured to cover the support structure 808. The cover 810 has a top 812 positioned on the top of the support structure 808, sides 814 extending around the outside of the support structure 808, and a bottom (not shown) that substantially encloses the support structure 808. The support structure 808 is configured to support a user sleeping or resting on the mattress 806 and may include foam, springs, an inflatable air chamber, and / or one or more other suitable mattress components. The cover 810 may also include an additional padding layer 816 on the top 812, such as a pillow top layer, a ticking layer, and / or other material layers suitable for the application.

[0282] The mattress 806 may include a head section 820 and a foot section 822. The foot warming system 802 may be positioned at or near the foot section 822 of the mattress 806, configured to warm the feet of a user lying on the mattress 806. As shown in Figure 27, the foot warming system 802 may include one or more heating units 824, 826, envelopes 828, 830, electrical connectors 832, 834 (e.g., one or more cables or wires), and one or more power supplies (as shown in Figure 27). In some embodiments, the power supplies may be a pump controller (e.g., an air chamber controller 1300 shown in Figures 1 and 2) or a joint movement controller (e.g., for controlling joint movement on an adjustable base). In other embodiments, the power supplies may be another controller or power supply suitable for the application.

[0283] The heating units 824 and 826 may be positioned inside the mattress 806. In some embodiments, the heating units 824 and 826 may include a conductive fabric, such as a carbon-filled polymer material, for generating heat. In other embodiments, the heating units 824 and 826 may have other electrical assemblies suitable for the application, such as a resistant wire and fabric. The heating units 824 and 826 may be positioned inside the mattress cover 810 and on top of the support structure 808, so as to be located between the support structure 808 and the mattress cover 810. The conductive fabric may be relatively flexible and able to heat relatively uniformly, providing a positive user foot-warming experience with little to no adverse effect on the softness or overall comfort of the mattress 806.

[0284] In some embodiments, heating units 824, 826 can be attached to the support structure 808. For example, Figure 27 shows a heating unit 824 attached to the support structure 808 via an envelope 828. The heating unit 824 may be positioned inside the envelope 828, which can be fixed to the top of the support structure 808 via adhesive, thread, or another mechanism suitable for the application.

[0285] In the illustrated example, the heating unit 824 is removablely inserted into the envelope 828 and is therefore removablely attached to the support structure. For example, the heating unit 826 is shown removed from the corresponding envelope 830. Thus, the envelopes 828 and 830 allow the heating units 824 and 826 to be retained in place relative to the mattress 806 while being removable for repair or replacement.

[0286] In some embodiments, the envelopes 828, 830 may be omitted. For example, in some embodiments, the heating units 824, 826 may be fixed to the support structure 808 without the envelopes 828, 830. In other embodiments, the heating units 824, 826 may be attached to the cover 810, the flame-retardant cap 836 (Figures 28 and 29), or other layers inside the mattress 806. Such attachments may be made via adhesive, stitching, or other fastening mechanisms suitable for the application.

[0287] Figure 27 shows the mattress 806 with the cover 810 partially removed to show the internal components, although the cover 810 can be closed during the normal operation of the mattress 806 to substantially conceal the foot warming system 802.

[0288] The power supply may be electrically connected to the heating units 824 and 826, and may selectively drive (i.e., supply power to) the heating units 824 and 826 to heat the mattress 806 at or near the foot area 822. This may warm the mattress 806 at the user's feet, for example, to improve comfort and / or to help induce sleep more quickly.

[0289] In some implementations, the envelope 828 may be embedded within the mattress. For example, the envelope 828 may be positioned inside the foam layer of the mattress (e.g., a top layer similar to the top layer 902), and wires from the envelope 828 may be routed through the foam layer (e.g., the sides of the foam layer) and extend from there. In this embodiment, the mattress may provide or maintain comfort from the foam layer, in contrast to another embodiment in which the embedded envelope 828 is exposed on the top of the mattress (or the top of the foam layer).

[0290] Figure 28 is a schematic end view of the mattress 806 and foot warming system 802. Figure 29 is a schematic side view of the mattress 806 and foot warming system 802. As shown in Figures 28 and 29, the mattress 806 may include a flame-retardant (fireproof) cap 836 positioned inside the cover 810. The flame-retardant cap 836 may cover the internal components of the mattress, including the support structure 808 and the components of the foot warming system 802 (including envelopes 828, 830 and heating units 824 positioned within them). In some embodiments, the flame-retardant cap 836 may include a 4-ounce jersey knit material. In other embodiments, the flame-retardant cap 836 may include one or more other materials suitable for the application. In yet another embodiment, the flame-retardant cap 836 may be omitted.

[0291] Referring to Figure 28, one embodiment of the support structure 808 may include a form 838 and air chambers 840, 842. In the illustrated embodiment, the form 838 is an inverted form tab covering the air chambers 840, 842. The air chambers 840, 842 are adjustable inflatable air chambers, each sized to support a first and second user, respectively, and may be identical or similar to the aforementioned air chamber 222 (Figure 3). The envelopes 828, 830 may be bonded to the form 838 or otherwise attached with the heating units 824, 826 positioned inside.

[0292] Referring to Figures 28 and 29, exemplary embodiments of the positioning of electrical connectors 832 and 834 are illustrated. As shown in Figures 28 and 29, the electrical connectors 832 and 834 include wires that extend along the sides of the mattress 806, partially through the foam 838. The foam 838 may define paths that allow the electrical connectors 832 and 834 to be routed through it. In one embodiment, the electrical connector 832 may be routed through a slit cut into the foam 838. In another embodiment, the electrical connector 832 may be routed through a hole drilled through the foam 838. The electrical connectors 832 and 834 may be terminated at connector ends 844 and 846, which may be connected to one or more power sources (not shown in Figures 28 and 29) for supplying power to heating units 824 and 826.

[0293] Referring to Figure 29, the connector 834 (from the side view) may extend from the envelope 830 near the foot portion 822 of the mattress 806 (with the heating unit 826 positioned internally) to the connector end 846 positioned near the longitudinal center of the mattress 806. By positioning the connector end 846 near the longitudinal center of the mattress 806, the mattress 806 can be used with an adjustable base to raise and lower the head portion 820 and foot portion 822 of the mattress 806 while allowing the connector end 846 to remain relatively stationary during joint movement. This allows the heating units 824, 826 to be raised and lowered with the mattress 806 while being connected to and powered by a relatively stationary power source during joint movement.

[0294] Figure 30 is a plan view of the components of the foot warming system 802. In the embodiment shown in Figure 30, the heating unit 824 includes heating elements (heating elements 864, 866, 868, 870) which are conductive fabrics, busbars 872, 874, reinforcing tapes 876, 878, a temperature sensor 880, wires 882, 884, 886, and a bonding film 888. The connector 832 may be a wire harness including wires 882, 884, 886. Wire 882 electrically connects busbar 872 to the controller (power supply) 890, and wire 886 electrically connects busbar 874 to the controller 890. Wire 884 electrically connects temperature sensor 880 to the controller 890, and the controller 890 may receive a temperature signal from temperature sensor 880 and supply power to the heating unit 824 as a function of the received temperature signal. Although only one wire 884 connected to the temperature sensor 880 is shown, multiple wires may be used. In some embodiments, the controller 890 may include or be part of the foot warming control system 116 (Figure 1). Alternatively, the controller 890 may be included in a pump controller (e.g., the air chamber control system 114 shown in Figure 1), a joint movement controller (e.g., the bed joint movement system 112 shown in Figure 1), or an airflow layer control system (e.g., the airflow insertion pad control system 118 shown in Figure 1). In some such embodiments, the controller 890 may perform some or all of the functions described above with respect to the controller, or none of them. In other embodiments, the controller 890 may be another controller or power supply suitable for the application. For example, the controller 890 may be a controller dedicated to operating the foot warming system 802 alone, or to operating the foot warming system 802 in combination with one or more other systems.

[0295] In some embodiments, multiple conductive fabric heating elements may extend from busbar 872 to busbar 874. In the illustrated embodiment, four separate fabric heating elements (heating elements 864, 866, 868, and 870) are included. The gaps separating adjacent heating elements 864, 866, 868, and 870 are illustrated. In some embodiments, the gaps between adjacent heating elements 864, 866, 868, and 870 may be about 0.5 inches. In some embodiments, the gaps between adjacent heating elements 864, 866, 868, and 870 may be between 0.2 inches and 0.8 inches. In other embodiments, more or fewer heating elements may be used.

[0296] In some embodiments, the heating elements 864, 866, 868, and 870 may include a carbon-based conductive fabric. This carbon-based conductive fabric can conduct electricity between the busbars 872 and 874 and has suitable resistance for generating heat. The heating elements 864, 866, 868, and 870 can operate at relatively low power and heat relatively uniformly, thereby warming the mattress while reducing the risk of fire. For example, in some embodiments, the power of the heating unit 824 is approximately 0.085–0.095 W / inch 2 It is possible.

[0297] In some embodiments, the busbars 872 and 874 may be tinned copper bus wires having a relatively small diameter to allow for repeated bending when the mattress is in use. In some such embodiments, the busbars 872 and 874 may include wire braids. In other embodiments, the busbars 872 and 874 may include conductive ink. In other embodiments, the busbars 872 and 874 may have different forms suitable for the application.

[0298] The temperature sensor 880 can sense the temperature of the heating unit 824 and its surroundings and provide feedback to the controller 890 for supplying power to the heating unit 824. In some embodiments, the temperature sensor 880 may be positioned close to the heating element 870. In some such embodiments, the temperature sensor 880 may be close to the heating element 870, but slightly separated from it, via a material layer such as a polyimide film layer. In various embodiments, the temperature sensor 880 may be a thermistor, a thermocouple, or another suitable temperature sensor.

[0299] Reinforcement tapes 876, 878 may be positioned along the edges of the heating elements 864, 866, 868, 870 and the busbars 872, 874 to reinforce the heating unit 824. The bonding film 888 may include top and bottom layers of film that enclose the heating elements 864, 866, 868, 870, the busbars 872, 874, the reinforcement tapes 876, 878, the temperature sensor 880, and parts of the wires 882, 884, 886. The bonding film 888 may protect the components contained therein from moisture and tampering (interference). In some examples, the bonding film 888 may be polyurethane or other polymer material suitable for enclosing the flexible heating elements 864, 866, 868, 870.

[0300] The heating unit 824 may be a relatively thin layer sized and configured to be positioned inside the mattress to warm the user's feet. In some embodiments, the heating unit 824 may be sized and positioned to heat only a limited portion of the mattress, including the user's feet but not the user's head and torso. In some embodiments, the heating unit 824 may have a width between 21 and 31 inches and a depth between 10 and 20 inches. In some embodiments, the heating unit 824 may have a width between 25 and 28 inches and a depth between 14 and 18 inches. In other embodiments, the size and position of the heating unit 824 may be modified to suit the application.

[0301] During operation, the controller 890 may selectively supply power to the heating unit 824 (and / or heating unit 826) to generate heat and warm the mattress 806. The foot warming system 802 may be controlled automatically, via input from a user interface (e.g., a mobile device or other remote control), or both. Automatic control may be performed as a function of several sensed events, such as the user getting in or out of bed, and / or the user falling asleep or waking up.

[0302] The controller 890 may have intelligence that allows for advantages such as preheating, timed shutoff, temperature control via the temperature sensor 880, or other features that may improve the user experience. For example, the foot warming system 802 may be controlled as a function of when the user goes to sleep. In one example, the user may specify the earliest time they go to sleep. The controller 890 may then drive the heating unit 824 to warm it for a predetermined time (e.g., 30 minutes) before this sleep time, so that the mattress 806 is warm when the user gets into it. In another example, the foot warming system 802 may be turned on via a user instruction via a user interface indicating the user's intention to go to sleep. When the user gets into the mattress 806, the foot warming system 802 may automatically shut off based on sensing that the user has entered the mattress 806, or it may continue operating for a given time. In another example, the foot warming system 802 may continue operating until the user falls asleep, as determined by one or more sensors.

[0303] During operation, the foot warming system 802 may maintain a constant temperature level or adjust to a preset level in response to one or more temporal or sensed events. The foot warming system 802 may operate at different power levels as appropriate depending on the situation. For example, the foot warming system 802 may initially operate at a high power level to quickly heat the mattress 806, and then operate at a lower power level to maintain the target temperature, such as by operating via pulse wave modulation.

[0304] In another example, the controller 890 may determine the expected bedtime of the user in the bed. This determination may be made as a function of user input regarding bedtime. Alternatively, this determination may be made automatically by the controller 890 as a function of a learned sleep schedule based on sensed data of the user who has historically gone to bed each night. Based on this information, the controller 890 may activate the foot warming system 802 to heat the foot portion of the mattress 806 to reach a target temperature before the expected bedtime.

[0305] In some such applications, the controller 890 may reduce power when a sensor detects that a user has entered the mattress 806. For example, the controller 890 may immediately cut off power so that the foot warming system 802 is heated only before the user enters the bed. Alternatively, the controller 890 may gradually reduce power after the user has entered the mattress 806, or reduce power after a given period of time.

[0306] In another example, the controller 890 may determine whether the user is asleep as a function of the sensed data, and then drive the foot warming system 802 as a function of whether or not the user is determined to be asleep. For example, the foot warming system 802 may be driven until the user falls asleep and is shut off in response to the determination that the user is asleep based on the sensed data.

[0307] In another example, the controller 890 may automatically activate the foot warming system 802 to improve sleep quality. For example, the controller 890 may have access to historical sleep metrics representing the quality of the user's sleep while the user is sleeping in bed, and / or to historical sensor data representing sensor readings, such as sensed temperature, that measure environmental conditions affecting the user while the user is sleeping. The controller 890 may identify instances of low-quality sleep and high-quality sleep experienced by the user in the historical sleep metrics, and then generate a correction plan specifying changes to the foot warming system to improve sleep quality based on the historical sleep metrics associated with the high-quality sleep. The controller 890 may then activate the foot warming system 802 according to the generated correction plan. The correction plan may be based on the user's own sleep data, and / or on aggregated sleep data from other individuals.

[0308] In another example, the controller 890 may achieve a desired temperature as a function of a sensed temperature, such as that sensed by the temperature sensor 880. The controller 890 may drive the heating unit 824 as a function of the difference between the sensed temperature and the target temperature, and the controller 890 may supply more power to the conductive fabric in response to determining a relatively large difference between the sensed temperature and the target temperature, while supplying less power to the heating unit 824 (conductive fabric) in response to determining a relatively small difference between the sensed temperature and the target temperature.

[0309] In various embodiments, the foot warming system 802 may be operated to improve user comfort and / or to induce faster sleep onset. Studies have shown that warming a user's feet when getting into bed can help some users fall asleep more quickly and improve sleep quality. The foot warming system 802 may be integrated into the mattress in a location suitable for a particular user with little to no adverse effect on mattress comfort. The foot warming system 802 may actively monitor the microclimate to maintain an appropriate temperature. The foot warming system 802 may be automatically controlled via sensed data to reduce or eliminate the need for user input. Various embodiments described herein may achieve one or more of these advantages, among other things.

[0310] The bed 800 may combine the foot warming system 802 with one or more other features described herein. For example, the bed 800 may include the foot warming system 802 within a mattress system 200 (as described with respect to Figures 1 to 10) which includes some or all of the features described herein with respect to the mattress system 200, such as the airflow pad assembly 232 and the airflow insertion pad control system 118. Thus, the bed 800 can use the airflow insertion pad control system 118 to supply or draw in heated air, cooled air, and / or ambient air, while using the foot warming system 802 to warm the feet separately. In some embodiments, by including both air and foot warming within the bed 800, many of the advantages described herein can be achieved more efficiently and effectively than when using air alone or foot warming alone.

[0311] In some embodiments, the bed 800 may be configured to be heated via a foot warming system 802 and cooled via an airflow insertion pad control system 118. In one example, the airflow insertion pad control system 118 may be configured to draw air from the user (or supply ambient air to the user) to cool the user at appropriate times. As a result, the airflow insertion pad control system 118 does not need to include a heating or cooling device and may consequently use less energy. Heat may be provided via the foot warming system 802 when desired. For example, heat may be provided via the foot warming system 802 before the user enters the bed 800 to help induce rapid sleep and then cut off when it is no longer needed. Cooling may then be provided via the airflow insertion pad control system 118 while the user is sleeping to avoid (or improve) the accumulation of excess heat. Alternatively, the foot warming system 802 may be used simultaneously with the airflow insertion pad control system 118 used to draw in air, which may have the effect of drawing air from the foot warming system 802 across the user's body and warming the user's body without requiring the addition of a heating unit to the airflow insertion pad control system 118. In a further alternative, the foot warming system 802 may be used simultaneously with the airflow insertion pad control system 118 used to supply air, which may have the effect of warming the user's feet while simultaneously cooling the user's core (center of the body).

[0312] In some implementations, the heating elements 864, 866, 868, and 870 may include resistive wire elements instead of, or in addition to, the conductive materials described herein. In some implementations, the heating unit 824 may include a thermostat integrated therein.

[0313] [Mattress surface treatment (feature group #12)] Figure 31 shows an exemplary mattress surface treatment for improving climate control of the mattress top surface. In this example, the exemplary bed 900 includes a mattress 901 and a base 903, which may be configured to be identical or similar to the mattresses and bases described herein with reference to, for example, Figures 1 to 30. Generally, the mattress 901 may be configured as a climate-controlled mattress and includes a mattress core, an air distribution layer, air hoses, an air controller, and a mattress cover. The mattress core is configured to support a user resting on the mattress. The air distribution layer is configured to facilitate airflow for climate control of the mattress top surface. The air hoses are configured to route ambient air or conditioned air into and out of the air distribution layer. The air controller is fluidically connected to the air distribution layer via the air hoses and operates to allow ambient air or conditioned air to flow into or out of the air distribution layer. The mattress cover is used to encompass at least a portion of the mattress core, air distribution layer, and air hoses.

[0314] The mattress may further include one or more mattress surface treatment mechanisms to improve the climate control effect of the mattress. In some implementations, the mattress includes stitching having a relatively high heat capacity provided on the mattress cover. For example, the mattress cover is manufactured at least partially from a fabric with threads having a relatively low first heat capacity, and further includes stitching on the top surface of the mattress. The stitching may be manufactured from a material having a relatively high second heat capacity compared to the first heat capacity, so that the stitching can better resist (withstand) temperature changes at the top of the mattress. For example, the stitching may better conserve the energy of cooling air or ambient air (lower than body temperature) and may help resist being warmed by the user's body temperature when the user rests on the mattress. The stitching material can be of various types. Examples of stitching materials include polypropylene threads, nylon threads, etc. Also, a foam layer may be positioned below the mattress cover. The foam layer may be manufactured from a material having a lower heat capacity than the stitching material.

[0315] Another example of a mattress surface treatment mechanism includes a gel layer. The gel layer may be positioned close to the top surface of the mattress. For example, the gel layer may be positioned beneath the mattress cover. Alternatively, the gel layer may be configured as part of the mattress cover. The gel layer may have a substantially higher heat capacity than the air distribution layer. In some implementations, the gel layer may be selected such that the ratio of the heat capacity of the gel layer to the heat capacity of one of the other layers or mattress components (e.g., top layer 902, middle layer 904, rail structure 906, bottom layer 908, air chamber assembly 920, and airflow layer 930) is greater than approximately 1.05, approximately 1.50, approximately 2.00, or approximately 5.00. Thus, the gel layer can better resist (withstand) temperature changes on the top surface of the mattress. For example, the gel layer may help better conserve the energy of cooling air or ambient air (lower than body temperature) and help resist being warmed by the user's body temperature when the user rests on the mattress. Furthermore, the foam layer may be positioned above the air distribution layer and below the gel layer. The foam layer may have a heat capacity smaller than that of the gel layer.

[0316] Referring to Figure 31, the mattress 901 may include a top layer 902, an intermediate layer 904, a rail structure 906, a bottom layer 908, an air chamber assembly 920, and an airflow layer 930, which may be configured to be identical or similar to the top layer, intermediate layer, rail structure, bottom layer, air chamber assembly, and airflow layer described above. Furthermore, the mattress 901 includes a mattress cover 940 having a top surface, a bottom surface, and sides, configured to at least partially cover the top layer 902, intermediate layer 904, rail structure 906, bottom layer 908, air chamber assembly 920, and airflow layer 930.

[0317] The mattress cover 940 may include stitching 960. The stitching 960 has a relatively high heat capacity. For example, the mattress cover 940 is manufactured from a fabric having yarn that has a lower heat capacity than the stitching 960, at least in part. The stitching 960 can be manufactured from various types of stitching materials. Examples of stitching materials include polypropylene yarn, nylon yarn, etc. Additionally, the top layer 902 positioned beneath the mattress cover 940 may be manufactured from a foam material having a lower heat capacity than the stitching 960. The stitching 960 can be arranged on the mattress cover 940 in various patterns. For example, the stitching 980 can be routed on or around the mattress in various sizes (e.g., width, height, etc.) and / or lengths. Additionally, the stitching 980 may have different colors.

[0318] Additionally or alternatively, the mattress 901 may include a gel layer 970. The gel layer 970 may be positioned below the mattress cover 940. Additionally, the gel layer 970 may be positioned above the top layer 902, the intermediate layer 904, and the airflow layer 930. For example, the gel layer 970 may be positioned on top of the top foam layer (e.g., the top layer 902). In some implementations, the gel layer 970 may be configured as part of the mattress cover 940. The gel layer 970 may have a higher heat capacity than the top layer 902, the intermediate layer 904, and / or the airflow layer 930. The gel layer 970 may be manufactured from various types of gel materials.

[0319] Alternatively or additionally, the top layer 902 (e.g., manufactured from foam) may be surface-treated with one or more gel materials having a different heat capacity than the top layer 902. For example, the heat capacity of a gel material incorporated into the top layer 902 may be higher than that of the top layer 902, and may provide prolonged warmth or coolness through the mattress when the bed is in a heated air supply mode or a cooled air supply mode, and may promote heat absorption from the user's body onto the mattress or into the surrounding environment when the bed is in a cooling mode where ambient air is drawn in from the top of the mattress. In some implementations, one or more gel materials may be incorporated into the top layer 902 by surface injection. For example, as shown in Figure 61 (the top layer 902 is folded to partially show the top surface of the top layer 902), a portion 950 of the top layer 902 may be surface-treated with a gel material to provide a higher heat capacity than the rest of the top layer 902. The portion 950 to be surface-treated may be part of the top layer 902, positioned to correspond to the airflow layer 930 below the top layer 902.

[0320] For example, the top layer 902 (e.g., a portion thereof 950) may be treated with a water-based surface injection, resulting in the top layer 902 containing a water-based surface coating with a high content of phase-change material. Various coatings can be used. One example of such a coating is AquaCool®, available from Peterson Chemical Technology. In some implementations, the coating may be applied to the top layer 902 and configured to produce an adhesive, breathable, flexible, and durable coating for various applications such as mattress layers, toppers, and other comfort products. Additionally, the coating may be configured to facilitate heat flow for cooling or temperature maintenance for comfort. The coating may offer various coating thicknesses and may be configured to be easily cured with water or other liquids. Furthermore, the coating may be applied to the top layer by roll coating or spraying. The coating may be configured to provide the top layer with a breathable layer of cool, flexible phase-change coating to help maintain airflow and moisture transmission. Furthermore, the coating may function as a medium for lateral heat transfer. The coating is configured to enhance cooling without excessive weight, improving heat capacity, heat transfer coefficient, and thermal osmosis. The coating may be enhanced with additives for additional heat transfer properties to aid in the regeneration of the phase change material (PCM), or for antimicrobial effects. Examples of such heat transfer additives include LumaCool®, black diamond, ceramic, titanium, copper, etc. Examples of antimicrobial additives include copper, silver, etc.

[0321] Additionally or alternatively, other layers and components within the mattress, such as the intermediate layer 904, rail structure 906, bottom layer 908, air chamber assembly 920, and airflow layer 930, may be processed to incorporate one or more gel materials in the same or similar manner as the top layer 902 described above.

[0322] [Airflow mattress with a water-resistant layer (feature group #14)] Figure 32 schematically illustrates an exemplary water-resistant layer that may be used with the mattresses described herein, for example with reference to Figures 1 to 31. Generally, a mattress with a water-resistant layer includes a mattress core, an air distribution layer, air hoses, and a mattress cover. The mattress core is configured to support the user and may be of various types, such as one or more inflatable air chambers, foam and / or spring assemblies. The air distribution layer is positioned above the mattress core and is configured to facilitate airflow for climate control of the mattress top surface. Air hoses are connected to the air distribution layer and are configured to route ambient air or regulated air between the air distribution layer and the air controller. The mattress cover has a mattress cover top surface, at least a portion of which is made of fabric configured to allow airflow between the air distribution layer and the space above the mattress top surface and to resist the flow of liquid water into the mattress when liquid water is positioned on the mattress cover top surface. In some implementations, the fabric of the mattress cover can substantially prevent the flow of liquid water into the mattress at atmospheric pressure.

[0323] Referring to Figure 32, the mattress 980 may include a pair of inflatable air chambers 982 (or other mattress cores) and an air distribution layer 984 positioned on the air chambers 982. The air distribution layer 984 is fluidly connected to an air controller 988 via an air duct 990. The air controller 988 is configured to allow ambient air or regulated air to flow into or out of the air distribution layer 984. The mattress 980 may further include a mattress cover 986 that at least partially covers the air chambers 982, the air distribution layer 984, and the other components of the mattress 980. The mattress cover 986 has a top surface 992 made of fabric that allows airflow through it while resisting the flow of liquid into the mattress when the liquid is positioned on the top surface of the mattress.

[0324] Alternatively or in addition to the mattress cover 986, the mattress 980 may include a mattress protector separate from the mattress cover 986, which allows airflow through it and is configured to resist the flow of liquid into the mattress when the liquid is positioned at the top of the mattress protector.

[0325] [Overview of Bed Control] Figure 33 is a block diagram of an example of various components of a bed system. For example, these components may be used in an exemplary bed system 1100. The bed system 1100 may be used to implement the bed described herein, for example with reference to Figures 1 to 32. The bed system 1100 may include multiple components to provide various functions of the bed system 1100. For example, the bed system 1100 includes an air chamber control system 1300, a bed joint motion control system 1400, a foot warming control system 1500, and an airflow pad control system 1600. The bed system 1100 may include a server system 1126 that can communicate with at least one of the systems 1300, 1400, 1500, and 1600 via a network 1128. The bed system 1100 may further include a remote control 1122 and a user computing device 1124 configured to allow a user to interact with the bed system 1100. The remote control 1122 and / or user computing device 1124 can communicate with the server system 1126 using the network 1128.

[0326] The air chamber control system 1300 can control one or more air chambers contained within the mattress and configured to provide the user with the desired firmness of the mattress. The bed joint motion control system 1400 can control the position (posture) of the adjustable base of the bed system 1100. The foot warming control system 1500 can control one or more foot heating elements contained within the mattress to provide the foot portion of the mattress with the desired temperature. The airflow pad control system 1600 can control the airflow through the airflow pad contained within the mattress to provide the top of the mattress with the desired temperature and / or humidity. Systems 1300, 1400, 1500, and 1600 are described in more detail with reference to Figures 34 to 37.

[0327] The user of the bed system 1100 may use one or more input devices, such as the remote control 1122 and the user computing device 1124, to input a desired operating mode, a desired temperature setting, a desired humidity setting, a desired bed position setting, and other appropriate settings for the bed system 1100. For example, the remote control 1122 may be used to implement the bedside controller 132, as shown in Figure 1.

[0328] The remote control 1122 may include a display 1142, a pressure selection input device 1144, a foot temperature selection input device 1146, a climate control selection input device 1148, and a bed joint movement input device 1150. The pressure selection input device 1144 is configured to allow the user to increase or decrease the pressure in the air chambers of the air chamber control system 1300. Adjusting the pressure in the air chambers may result in a corresponding adjustment to the stiffness of each air chamber. The foot temperature selection input device 1146 is configured to allow the user to increase or decrease the temperature of the heating units of the foot warming control system 1500. The climate control selection input device 1148 is configured to allow the user to select one or more operating modes for the airflow layer (e.g., airflow pad) and / or adjust the temperature of the airflow layer in the airflow pad control system 1600. The bed joint movement input device 1150 is configured to allow the user to adjust the bed position (tilt, recline, etc.) in the bed joint movement control system 1400. The input device for the remote control 1122 can be of various types, such as mechanical and / or virtual buttons or switches. In some implementations, the bed system 1100 includes multiple remote controls 1122 for separately controlling different parts of the bed (e.g., the left and right sides of the bed). In other implementations, a single remote control 1122 is configured to allow the user to control different parts of the bed. The remote control 1122 can be a dedicated wireless remote control, a dedicated wired remote control, a smartphone or other mobile device running a remote control application, or another remote control suitable for remote control functionality. The remote control 1122 may be omitted or modified as appropriate for the application. For example, in some embodiments, the bed 1112 may be controlled by a computer, tablet, smartphone, or other device communicating with the bed 1112, either wired or wirelessly, in addition to using one or more remote controls 1122.

[0329] In some implementations, data may be transmitted from a component to one or more processors (e.g., processors in systems 1300, 1400, 1500, 1600) or to one or more display devices such as display 1142. For example, various pieces of information associated with the bed, such as the current foot warming temperature determined by the sensor element of the temperature controller, the current airflow layer temperature determined by the sensor element of the air controller, the bed pressure, sensed user biometrics, the current position of the base, or other information, may be transmitted to the respective controllers in control systems 1300, 1400, 1500, 1600. Such controllers may then transmit the received information to a remote control 1122, where it may be displayed to the user (e.g., on display 1142).

[0330] Similarly, the user computing device 1124 may be used by a user in bed and / or by a user located away from the bed. Exemplary user computing devices 1124 include, but are not limited to, mobile computing devices (e.g., mobile phones, tablet computers, laptops) and desktop computers. The user computing device 1124 includes one or more power supplies, processors, and computer-readable memory. User inputs and outputs may be transmitted through one or more user interfaces, such as speakers, touchscreens, pointing devices, keyboards, or other suitable input and output devices. The user computing device 1124 may run one or more applications to allow a user to interact with the bed system 1100. These applications may allow the user to view information about the bed (e.g., sensor readings, sleep metrics, etc.) or configure the behavior of the bed system 1100 (e.g., setting a desired firmness for the bed, setting a desired temperature for the foot warming unit, setting a desired temperature or airflow mode for the airflow pad, setting a desired behavior for peripheral devices, etc.). In some cases, the user computing device 1124 may be used in addition to or to replace the aforementioned remote control 1122. In some implementations, the user computing device 1124 may be used to implement a mobile computing device 134 as shown in Figure 1.

[0331] Server 1126 may include one or more computing devices. Server 1126 may be used to implement a server system 140 as shown in Figure 1. Server 1126 may be connected to a bed system 1100. For example, Server 1126 may be connected to at least one of systems 1300, 1400, 1500, and 1600 via network 1128. Server 1126 may further communicate with a remote control 1122 and / or a user computing device 1124 via network 1128 to allow a user to interact with components of the bed system 1100. Network 1128 may be similar to network 142 in Figure 1. Server 1126 may be connected to a database to provide various services. For example, Server 1126 may be configured to access bed data 1130 for bed data services, sleep data 1132 for sleep data services, user account data 1134 for user account services, and environment data 1136 for environment services. Bed data 1130, sleep data 1132, user account data 1334, and environment data 1136 may be similar to bed data 150, sleep data 152, user account data 154, and environment data 156 as shown in Figure 1. The bed data service, sleep data service, user account service, and environment service executed using server 1126 may be similar to the bed data service, sleep data service, user account service, and environment service described with reference to Figure 1.

[0332] Although systems 1300, 1400, 1500, and 1600 are illustrated herein as separate systems or units, it will be understood that some or all of these systems may be combined and operated as a single unit. For example, one or more components and / or functions of the controllers within systems 1300, 1400, 1500, and 1600 may be integrated and configured as a single control box that communicates with and controls other components such as pumps, adjustable bases, foot heating elements, and airflow pads.

[0333] Figure 34 is a block diagram of an example of an air chamber control system 1300 that may be associated with a bed system, including those described herein with reference to, for example, Figures 1, 8 to 10, 19 and 33. The air chamber control system 1300 may include an air chamber controller 1302, a pump assembly 1304, one or more air chambers 1306, and a set of sensors 1308.

[0334] The air chamber controller 1302 can control the pump assembly 1304 and activate and control the pressure in the air chamber 1306 contained within the mattress 1310. The air chamber controller 1302 can be used to implement at least a portion of the air chamber control system 114 shown in Figure 1. In some implementations, the air chamber controller 1302 may be configured as the center or hub of the bed system 1100 and can activate and control various functions provided within the bed system, such as at least some functions of the foot warming control system 1500 and the airflow pad control system 1600.

[0335] In some implementations, the air chamber controller 1302 may include a power supply 1320, a processor 1322, and memory 1324. The power supply 1320 includes hardware used to receive power from an external power source and supply it to the components of the air chamber controller 1302. The power supply 1320 may include, for example, a battery pack and / or a wall outlet adapter, an AC-to-DC converter, a DC-to-AC converter, a power regulator, a capacitor bank, and / or one or more interfaces to provide power of the type such as current and voltage required by the other components of the air chamber controller 1302.

[0336] The processor 1322 may be one or more processors that receive inputs, perform logical decisions, and provide outputs. The processor 1322 may be a central processing unit, a microprocessor, a general-purpose logic circuit, an application-specific integrated circuit, a combination thereof, and / or other hardware to perform the required functions.

[0337] Memory 1324 is used to store (store) data and software code and / or firmware code that can be executed by the processor 1322. Memory 1324 may include long-term stable data storage (e.g., on a hard disk), short-term unstable data storage (e.g., on random-access memory), or any other technically appropriate form.

[0338] The air chamber controller 1302 may include a pump controller 1326 and a pump motor 1328, which may be housed in a common housing (such as a plastic or metal pump housing). The pump controller 1326 may receive commands from the processor 1322 and, accordingly, control the function of the pump motor 1328. For example, the pump controller 1326 may receive a command from the processor 1322 to increase the pressure in the air chamber 1306 by 0.3 pounds per square inch (PSI). The pump controller 1326 may, accordingly, act on a valve configured to send air into the selected air chamber 1360, operating the pump motor 1328 for a time corresponding to 0.3 PSI, or until a sensor indicates that the pressure has increased by 0.3 PSI. In an alternative form, the message may specify that the air chamber 1360 should be inflated to a target PSI, and the pump controller 1326 may operate the pump motor 1328 until the target PSI is reached.

[0339] In some implementations, the air chamber controller 1302 may include one or more valve solenoids 1330 that can control the connection between the pump and one or more air chambers. In some cases, the solenoids 1330 may be directly controlled by the processor 1322. In some cases, the solenoids 1330 may be controlled by the pump controller 1326. In some implementations, a valve controller 1332 may be provided to translate commands from the processor 1322 into control signals for the valve solenoids 1330. In one example, the processor 1322 may issue a command to the valve controller 1332 to connect the pump to a specific air chamber from a group of air chambers in an airbed. The valve controller 1332 may control the position of the valve solenoids 1330 so that the pump is connected to the designated air chamber.

[0340] The air chamber controller 1302 may include a communication interface 1334 to allow the air chamber controller 1302 to communicate with other components of the system 1300. For example, the air chamber controller 1302 may communicate with one or more peripheral sensors, peripheral controllers, circuits (e.g., foot heater control circuits, airflow pad control circuits, etc.), and / or computing devices via one or more wired or wireless networks. The communication interface 1334 may include, but is not limited to, multiple communication interfaces such as Wi-Fi, Bluetooth, and copper wire networks, and may provide any technically appropriate communication interface.

[0341] The air chamber controller 1302 may include a pressure sensor 1336 configured to read pressure readings from one or more air chambers 1306 of the airbed. The pressure sensor 1336 may also perform digital sensor adjustment. The pressure sensor 1336 may be specific to the air chamber controller 1302. Alternatively or additionally, the pressure sensor may be provided as a peripheral sensor, as described below.

[0342] The air chamber controller 1302 may provide a state analysis module 1338. For example, the state analysis module 1338 may be one or more software components stored in computer memory 1324 and executed by processor 1322. The state analysis module 1338 may receive data from a wide variety of sources (e.g., sensors, non-sensor local sources, cloud data services) and analyze various states and operating conditions of the bed system 1100. The state analysis module 1338 may further generate one or more actions to be taken (e.g., commands to be sent to peripheral controllers, data to be sent to cloud services). This may be useful, for example, when tracking user behavior or automating devices that communicate with the user's bed.

[0343] The state analysis module 1338 may collect data from any technically appropriate source to collect data about, for example, the bed's characteristics, the bed's environment, and / or the bed's user. Some such sources include any of the sensors from a set of sensors 1308. For example, this data may provide the state analysis module 1338 with information about the current state of the environment surrounding the bed. For example, the state analysis module 1338 may access readings from pressure sensors 1336 and 1344 to determine the pressure in the air chamber within the bed. From these readings, and possibly other data, the presence of a user in the bed may be determined. In another example, the state analysis module 1338 may access a light sensor 1348 to detect the amount of light in the bed's environment.

[0344] Similarly, the state analysis module 1338 may access data from cloud services, for example, via the server system 1126 (Figure 33). For example, the state analysis module 1338 may access a bed cloud service to access historical sensor data and / or high sleep data. Other cloud services, including those not previously described, may be accessed by the state analysis module 1338. For example, the state analysis module 1338 may access weather reporting services, third-party data providers (e.g., traffic and news data, emergency broadcast data, user travel data), and / or clock and calendar services.

[0345] Similarly, the state analysis module 1338 may access data from non-sensor sources. For example, the state analysis module 1338 may access local clock and calendar services (e.g., components of processor 1322).

[0346] The state analysis module 1338 can aggregate and prepare this data for use by one or more behavior algorithms. Behavior algorithms may be used to learn user behavior and / or perform certain actions based on the state of the accessed data and / or predicted user behavior. For example, a behavior algorithm may use available data (e.g., pressure sensor, non-sensor data, clock and calendar data) to create a model of when the user goes to sleep each night. The same or different behavior algorithms may then be used to determine whether an increase in air chamber pressure is likely to indicate the user is going to sleep, and if so, some data may be sent to a third-party cloud service and / or a peripheral controller may be activated.

[0347] In the illustrated example, the state analysis module 1338 (including the behavior algorithm) is shown as a component of the air chamber controller 1302. Alternatively, the state analysis module 1338 may be contained within other components within the bed system 1100. For example, the same or similar state analysis module and / or behavior algorithm may be executed in one or more cloud services (e.g., on the server system 1126), and the resulting output may be transmitted to the air chamber controller 1302, other components within the bed system 1100, or any other technically appropriate recipient.

[0348] Continuing with reference to Figure 34, the pump assembly 1304 can communicate bidirectionally with the air chamber controller 1302. The pump 1304 may include a motor 1362, a pump manifold 1364, a relief valve 1366, a first control valve 1368A, a second control valve 1368B, and a pressure transducer 1370. The pump 1304 is fluidly connected to the first air chamber 1306A and the second air chamber 1306B via a first pipe 1372A and a second pipe 1372B, respectively. The first and second control valves 1368A and 1368B may be controlled by a switching mechanism and are operable to regulate the fluid flow between the pump 1304 and the first and second air chambers 1306A and 1306B, respectively. The switching mechanism may be contained within the air chamber controller 1302 and may include, for example, a relay or a solid-state switch. In other implementations, the switching mechanism may be located within other components, such as the pump 1304, rather than within the air chamber controller 1302.

[0349] In some implementations, the pump 1304 and the air chamber controller 1302 may be provided and packaged as a single unit within a common pump housing. In some alternative implementations, the pump 1304 and the air chamber controller 1302 may be provided as physically separate units. In some implementations, the air chamber controller 1302, the pump 1304, or both thereof, may be integrated into or contained within the bed frame or bed support structure supporting the bed 1112. In some embodiments, the air chamber controller 1302, the pump 1304, or both thereof, may be located outside the bed frame or bed support structure.

[0350] The exemplary bed system 1100 shown in Figure 33 includes two air chambers 1306A and 1306B and a single pump 1304. However, other embodiments may include an air bed system having two or more air chambers and one or more pumps incorporated within the air bed system to control the air chambers. For example, a separate pump may be associated with each air chamber of the bed system, or a single pump may be associated with multiple chambers of the bed system. The separate pump may allow each air chamber to be inflated or deflated independently and simultaneously. Furthermore, additional pressure transducers may also be incorporated within the bed system, for example, so that a separate pressure transducer may be associated with each air chamber.

[0351] During use, the processor 1322 may, for example, send a pressure reduction command to reduce the pressure in one of the air chambers 1306A, 1306B, and a switching mechanism may be used to convert the low-voltage command signal sent by the processor 1322 into a higher operating voltage sufficient to activate the relief valve (safety valve) 1366 of the pump 1304 and open the control valves 1368A, 1368B. Opening the relief valve 1366 may allow air to escape from the air chamber 1306A or 1306B through the respective air pipes 1372A or 1372B. During deflation, the pressure transducer 1370 may transmit pressure readings to the processor 1322 via an A / D converter. The A / D converter may receive analog information from the pressure transducer 1370 and convert this analog information into digital information usable by the processor 1322. The processor 1322 may transmit the digital signal to the remote control 1122 and / or user computing device 1124 to update the display in order to convey pressure information to the user.

[0352] As another example, processor 1322 may send a pressure increase command. Pump motor 1362 may be energized in response to the pressure increase command and electronically actuate the corresponding valves 1368A, 1368B to supply air to the designated one of the air chambers 1306A, 1306B via air pipes 1372A, 1372B. While air is being supplied to the designated air chamber 1306A or 1306B to increase the chamber's stiffness (rigidity), pressure transducer 1370 may sense the pressure in pump manifold 1364. In this case as well, pressure transducer 1370 may transmit the pressure reading to processor 1322 via A / D converter. Processor 1322 may use the information received from A / D converter to determine the difference between the actual pressure in air chamber 1306A or 1306B and the desired pressure. The processor 1322 may transmit the digital signal to the remote control 1122 and / or user computing device 1124 to update the display in order to convey pressure information to the user.

[0353] During the expansion or contraction process, the pressure sensed within the pump manifold 1364 may provide an approximation of the pressure in each air chamber that is in fluid communication with the pump manifold 1364. An exemplary method for obtaining a pump manifold pressure reading substantially equal to the actual pressure in the air chambers comprises the steps of turning off the pump 1304, allowing the pressures in the air chambers 1306A or 1306B and the pump manifold 1364 to equalize, and then sensing the pressure in the pump manifold 1364 using the pressure transducer 1370. This allows sufficient time for the pressures in the pump manifold 1364 and the chambers 1306A or 1306B to equalize, which can result in a pressure reading that is an accurate approximation of the actual pressure in the air chambers 1306A or 1306B. In some implementations, the pressures in the air chambers 1306A and / or 1306B may be continuously monitored using multiple pressure sensors (not shown).

[0354] In some implementations, the information collected by the pressure transducer 1370 can be analyzed to determine various states and / or biometric information of a person lying in bed. For example, the processor 1322 may use the information collected by the pressure transducer 1370 to determine the heart rate or respiratory rate of a person lying in bed. For example, the user may be lying on one side of the bed, which includes the chamber 1306A. The pressure transducer 1370 may monitor the pressure fluctuations in the chamber 1306A, and this information may be used to determine the user's heart rate and / or respiratory rate. As another example, additional processing may be performed using the collected data to determine the person's sleep state (e.g., wakefulness, light sleep, deep sleep). For example, the processor 1322 may determine when a person falls asleep, when they are asleep, and their various sleep states.

[0355] Additional information relating to the user of the bed system 1100, which can be determined using the information collected by the pressure transducer 1370, includes the user's movement, the user's presence on the bed surface, the user's weight, the user's cardiac arrhythmia, and temporary apnea. Taking the detection of the user's presence as an example, the pressure transducer 1370 may be used to detect the presence of a user on the bed, for example, by determining a change in total pressure and / or by one or more of the respiratory rate signal, heart rate signal, and / or other biometric signals. For example, a simple pressure sensing process may identify an increase in pressure as indicating the presence of a user on the bed. As another example, the processor 1322 may determine that a user is on the bed if the detected pressure increases above a certain threshold (a threshold to indicate that a person or other object exceeding a certain weight is placed on the bed). As yet another example, the processor 1322 may identify an increase in pressure in combination with detected slight rhythmic fluctuations in pressure as corresponding to the presence of a user on the bed. The presence of rhythmic fluctuations can be identified as being attributable to the user's breathing or heartbeat (or both). Breathing or heartbeat detection can distinguish the user present in bed from other objects (such as a suitcase) placed on the bed.

[0356] In some implementations, pressure fluctuations can be measured in pump 1304. For example, one or more pressure sensors may be placed in one or more internal cavities of pump 1304 to detect pressure fluctuations within pump 1304. Pressure fluctuations detected in pump 1304 may indicate pressure fluctuations in one or both chambers 1306A and 1306B. One or more sensors placed in pump 1304 may be in fluid communication with one or both chambers 1306A and 1306B, and the sensors may operate to determine the pressures within chambers 1306A and 1306B. The air chamber controller 1302 may be configured to determine at least one vital sign (e.g., heart rate, respiratory rate) based on the pressure in chamber 1306A or chamber 1306B.

[0357] In some implementations, the air chamber controller 1302 may analyze pressure signals detected by one or more pressure sensors to determine the heart rate, respiratory rate, and / or other vital signs of a user lying or sitting on chamber 1306A or chamber 1306B. For example, when a user lies on a bed positioned above chamber 1306A, each of the user's heart rate, respiration, and other movements may generate forces on the bed 1112 transmitted to chamber 1306A. As a result of the force input to chamber 1306A due to the user's movements, waves may propagate through chamber 1306A into pump 1304. Pressure sensors positioned in pump 1304 may detect these waves, and the pressure signals output by the sensors may indicate heart rate, respiratory rate, or other information about the user.

[0358] Regarding sleep states, the bed system 1100 can determine the user's sleep state by using various biometric signals, such as heart rate, respiration, and / or user movement. While the user is sleeping, the processor 1322 can receive one or more of the user's biometric signals (e.g., heart rate, respiration, and movement) and determine the user's current sleep state based on the received biometric signals. In some implementations, signals indicating pressure fluctuations in one or both chambers 1306A and 1306B may be amplified and / or filtered to allow for more accurate detection of heart rate and respiration.

[0359] The air chamber controller 1302 may execute a pattern recognition algorithm or other calculation method based on the amplified and filtered pressure signal to determine the user's heart rate and respiratory rate. For example, the algorithm or calculation method may be based on the assumption that the heart rate portion of the signal has a frequency in the range of 0.5 to 4.0 Hz, and the respiratory rate portion of the signal has a frequency in the range of less than 11 Hz. The air chamber controller 1302 may also be configured to determine other user characteristics based on the received pressure signal, such as blood pressure, rocking and rotational movements, rolling movements, limb movements, weight, the presence or absence of the user, and / or the user's identity (personality).

[0360] For example, a pressure transducer 1370 may be used to monitor the air pressure in chambers 1306A and 1306B of bed 1112. When the user on the bed is not moving, changes in the air pressure in air chamber 1306A or 1306B may be relatively small and may be due to breathing and / or heartbeat. However, when the user on the bed is moving, the air pressure in the mattress may fluctuate by a much larger amount. Therefore, the pressure signals generated by the pressure transducer 1370 and received by the processor 1322 may be filtered and shown as corresponding to movement, heartbeat, or breathing.

[0361] In some implementations, instead of performing data analysis within the air chamber controller 1302 using processor 1322, a digital signal processor (DSP) may be provided to analyze the data collected by the pressure transducer 1370. Alternatively, the data collected by the pressure transducer 1370 may be sent to a cloud-based computing system for remote analysis.

[0362] Continuing with reference to Figure 34, a set of sensors 1308 may include one or more sensors configured to sense environmental and / or physical phenomena of the bed and report such senses to the air chamber controller 1302 for analysis or other purposes. The sensors may include peripheral sensors 1340 that communicate with the air chamber controller 1302. Such peripheral sensors of the set of sensors 1308 may communicate with the air chamber controller 1302 via one or more network interfaces of the air chamber controller 1302, including but not limited to USB stacks, WiFi radios, Bluetooth Low Energy (BLE) radios, ZigBee radios, and Bluetooth radios, as appropriate for the particular form of sensor. For example, a sensor that outputs readings via a USB cable may communicate via a USB stack. Additionally or alternatively, the sensors may include sensors specific to the air chamber controller 1302.

[0363] Some of the peripheral sensors 1340 of a set of sensors 1308 may be bed-mounted sensors 1342. The bed-mounted sensors 1342 may, for example, be embedded within the bed structure and sold with the bed, or be attached to the bed structure later. Other peripheral sensors 1340 may communicate with the air chamber controller 1302 but may not be selectively mounted to the bed. In some cases, some or all of the bed-mounted sensors 1342 and / or peripheral sensors 1340 may share networking hardware. This includes conductors (wires) from each sensor, including wires, multi-wire cables, or plugs, which connect all the relevant sensors to the air chamber controller 1302 when attached. In some embodiments, one, some, or all of the sensors may be capable of sensing one or more features of the mattress, such as pressure, temperature, light, sound, and / or one or more other features of the mattress. In some embodiments, one, some, or all of the sensors are capable of sensing one or more external features of the mattress. The bed-mounted sensor 1342 may include one or more of the following: a pressure sensor 1344, a temperature sensor 1346, a light sensor 1348, an acoustic sensor 1350, and other suitable sensors for detecting one or more features of the mattress and / or one or more external features of the mattress. In this example, the pressure sensor 1344 is configured as a peripheral sensor that may be used as a replacement for or in addition to the pressure sensor 1336 in the air chamber controller 1302.

[0364] Figure 35 is a block diagram of an example of a bed joint motion control system 1400 that may be associated with a bed system, including those described herein with reference to, for example, Figures 1, 19, and 33. The bed joint motion control system 1400 may include a bed joint motion controller 1402 and an adjustable base 1404. The joint motion controller 1402 is configured to adjust the position of the bed by adjusting the adjustable base 1404 that supports the bed. The adjustable base 1404 may include one or more adjustable panels 1420 whose positions may be controlled by the joint motion controller 1402. The joint motion controller 1402 may be used to implement at least a portion of the bed joint motion system 112 of the bed control system 110 shown in Figure 1. In some implementations, the joint motion controller 1402 may include a processor 1410, memory 1412, power supply 1414, and motor 1416. In some implementations, the motor 1416 may be located within other components such as an adjustable base 1404.

[0365] For example, the joint movement controller 1402 can adjust the base 1404 from a flat position to a position where the head of the bed mattress is tilted upward (for example, to facilitate the user sitting on the bed and / or watching television). In some implementations, the base 1404 includes multiple independently articulated sections or panels. For example, parts of the base corresponding to the positions of air chambers 1306A and 1306B may be articulated independently of each other to allow one person sitting on the bed surface to rest in a first position (e.g., a flat position), while a second person rests in a second position (e.g., a reclined position with the head raised at a certain angle from the waist). In some implementations, separate positions may be set for two different beds (e.g., two twin beds placed adjacent to each other). The bed base 1404 may include multiple zones that can be adjusted independently. The joint motion controller 1402 may include a motor 1416 that can be energized in response to joint motion commands transmitted from the processor 1410. The motor 1416 is operably engaged with one or more joint motion panels of the base 1404 and adjusts the position of the joint motion panels based on the joint motion commands. The joint motion controller 1402 may also be configured to provide different levels of massage to one or more users on the bed. Joint motion commands may be generated by the processor 1410 based on user input about bed joint motion settings, for example, via the remote control 1122 and / or the user computing device 1124.

[0366] Referring again to Figure 33, the bed system 1100 may include one or more temperature control systems configured to raise, lower, or maintain the bed temperature, for example, for user comfort. As previously mentioned, such temperature control systems may include a foot warming control system 1500 and an airflow pad control system 1600.

[0367] Figure 36 is a block diagram of an example of a foot warming control system 1500 that may be associated with a bed system, including those described above with reference to Figures 1, 27 to 30 and 33. The foot warming control system 1500 may include a foot warming controller 1502 and one or more foot warming pads 1504A, 1504B. The foot warming pads 1504A, 1504B may be located at the foot of the mattress, on top of the mattress 1508, or may be part of the mattress 1508. The mattress 1508 may be implemented by the mattress 1310 in Figure 34. The foot warming pads 1504A, 1504B may include heating elements used to keep the pads warm to a desired temperature. The foot warming controller 1502 is coupled to the foot warming pads 1504A, 1504B and is operable to heat the heating elements of the pads to a desired temperature. The foot warming controller 1502 may include a processor 1512 and a memory 1514, the processor 1512 may generate control commands to supply energy to the heating element in accordance with user input for foot temperature settings, for example via a remote control 1122 or a user computing device 1124. The foot warming controller 1502 may include a communication interface 1516 to allow the foot warming controller 1502 to communicate with other components in the bed system 1100, such as at least one of the systems 1300, 1400, 1600, the remote control 1122, the user computing device, and the server system 1126.

[0368] The processor 1512 may generate a foot warming command in accordance with user input of foot temperature settings (for example, via the remote control 1122 or a user computing device) and transmit the foot warming command to the foot warming controller 1502. The foot warming controller 1502 may selectively activate the heating elements of the foot warming pads 1504A and 1504B to raise, lower, or maintain the foot warming pads 1504A and 1504B at a desired temperature. The foot warming controller 1502 may include a power supply 1510 for supplying power to activate the heating elements of the foot warming pads 1504A and 1504B.

[0369] In some implementations, temperature sensors 1506A and 1506B are provided to detect the temperature of the foot warming pads 1504A and 1504B and transmit the temperature readings to the foot warming controller 1502. The processor 1512 can use the temperature readings of the foot warming pads 1504A and 1504B to adjust the operation of the pads 1504A and 1504B as needed. Separate foot warming pads may be used on different sides of the bed 1112 (for example, corresponding to the locations of the air chambers 1306A and 1306B) to provide different temperature control on different sides of the bed.

[0370] A user of the bed system 1100 may use input devices such as a remote control 1122 and a user computing device 1124 to input a desired temperature for the foot warmer at the foot of the bed. The desired temperature may be encapsulated in a command data structure that includes the desired temperature and identifies the foot warmer controller as the desired controlled component. This command data structure may then be transmitted to the processor 1512 via Bluetooth or another suitable communication protocol. In various examples, the command data structure may be encrypted before transmission. The foot warmer controller 1502 may then configure (control) its elements to increase or decrease the temperature of the foot warmer pads in response to the temperature input by the user to the remote control 1122 or the user computing device 1124.

[0371] Figure 37 is a block diagram of an example of an airflow pad control system 1600 that may be associated with a bed system, including those described above with reference to Figures 1 to 33. The airflow pad control system 1600 may include an airflow pad controller 1602 and one or more airflow pads 1606. The airflow pads 1606A, 1606B may be placed within a mattress 1604 and may be configured to cool or heat at least a portion of the top of the mattress. The mattress 1604 may be implemented by mattress 1310 (Figure 34) or mattress 1508 (Figure 36). The airflow pads 1606A, 1606B may be used together with foot warming pads 1504A, 1504B. For example, the foot warming pads 1504A, 1504B may be placed at the foot of the mattress, while the airflow pads 1606A, 1606B may be placed at the head of the mattress, or in the middle section between the head and foot of the mattress, or in other areas of the mattress. The airflow pads 1606A and 1606B may be configured to be identical or similar to the airflow layers described herein with reference to, for example, Figures 1 to 3, Figures 5 to 13, and Figures 31 to 33. The airflow pads 1606A and 1606B are configured to allow ambient air or regulated air to flow through them so that air can be distributed through one or more layers on the airflow pad, or so that air can be drawn out from the layers on the airflow pad.

[0372] The airflow pad controller 1602 can be fluidly connected to the airflow pads 1606A and 1606B via air hoses 1608A and 1608B. The airflow pad controller 1602 is configured to control the temperature of the top surface of the top layer by moving ambient air or conditioned air through the airflow pads 1606A and 1606B and further through the top layer of the mattress. For example, the airflow pad controller 1602 may be operated to draw air from the airflow pads 1606A and 1606B and the top layer through the air hoses 1608A and 1608B, thereby lowering the temperature of the top surface of the top layer. Alternatively, the airflow pad controller 1602 may be operated to supply ambient air or cooling air to the airflow pads 1606A and 1606B through the air hoses 1608A and 1608B, thereby allowing such ambient air or cooling air to be distributed through the top layer and lowering the temperature of the top surface of the top layer. Alternatively, the airflow pad controller 1602 may be operated to supply heated air to the airflow pads 1606A and 1606B through the air hoses 1608A and 1608B, thereby allowing such heated air to be distributed through the top layer and raising the temperature of the top surface of the top layer.

[0373] In some implementations, the airflow pad controller 1602 may include an air fan 1610 and an air conditioner 1612, or may be coupled to them. The air conditioner 1612 may include an air heater 1614. Additionally, the air conditioner 1612 may include an air cooler 1616. The fan 1610 is configured to draw air into or out of the airflow pads 1606A and 1606B. The heater 1614 is configured to heat the air that enters or exits the airflow pads 1606A and 1606B. The cooler 1616 is configured to cool the air that enters or exits the airflow pads 1606A and 1606B. The air fan 1610 may be implemented by the air controller 700 described above with reference to Figures 21 to 26. The heater 1614 may be implemented by the heating element 716 described above with reference to Figures 22 to 26.

[0374] The airflow pad controller 1602 may include a processor 1620, memory 1622, fan control circuit 1624, air conditioner control circuit 1626, communication interface 1628, one or more temperature sensors 1630, one or more humidity sensors 1632, and a power supply 1634. The fan control circuit 1624 is configured to control the fan 1610 by allowing communication between the processor 1620 and the fan 1610. The air conditioner control circuit 1626 is configured to control the air conditioner 1612 by allowing communication between the processor 1620 and the air conditioner 1612. The communication interface 1628 is configured to allow the airflow pad controller 1602 to communicate with other components in the bed system 1100, such as at least one of the systems 1300, 1400, 1500, remote control 1122, user computing device 1124, and server system 1126.

[0375] The temperature sensor 1630 is configured and positioned to detect the temperature of the air flowing into and / or drawn out of the airflow pads 1606A, 1606B, the temperature of the air conditioner 1612 (e.g., heater 1614 or cooler 1616), the ambient air temperature, and / or other temperatures at different locations in the bed system. Such temperature measurements can be used to adjust the operation of the airflow pads 1606A, 1606B and / or other components of the bed system 1100. The temperature sensor 1630 can be positioned in various locations. In some implementations, one or more temperature sensors 1630 may be located within the housing of the airflow pad controller 1602. The housing of the airflow pad controller 1602 may also house the air fan 1610 and / or the air conditioner 1612 (e.g., heater 1614 and / or cooler 1616). For example, at least one of the temperature sensors 1630 may be positioned adjacent to the fan 1610 and / or the air conditioner 1612. Additionally or alternatively, one or more temperature sensors 1630 may be positioned outside the mattress, such as below the bottom of the mattress. Additionally or alternatively, one or more temperature sensors 1630 may be mounted at a desired location on the mattress (e.g., the bottom of the mattress). Additionally or alternatively, one or more temperature sensors 1630 may be positioned in the airflow path between the fan 1610 and the airflow pad 1606.

[0376] The humidity sensor 1632 is configured and positioned to detect the humidity values ​​of the air flowing into and / or drawn in from the airflow pads 1606A and 1606B, the humidity values ​​of the ambient air, and / or other humidity values ​​at different locations in the bed system. Such humidity measurements may be used to adjust the operation of the airflow pads 1606A, 1606B and / or other components of the bed system 1100. For example, the processor 1620 may use temperature and / or humidity measurements to adjust various operations of the airflow pad controller 1602, such as air conditioning, supplying or drawing air to and from the airflow pads 1606A and 1606B, and / or the operation of other components in the bed system 1100. The humidity sensor 1632 may be located in various places. In some implementations, one or more humidity sensors 1632 may be located within the housing of the airflow pad controller 1602. The housing of the airflow pad controller 1602 may also house the air fan 1610 and / or air conditioner 1612 (e.g., heater 1614 and / or cooler 1616). For example, at least one of the humidity sensors 1632 may be positioned adjacent to the fan 1610 and / or the air conditioner 1612. Additionally or alternatively, one or more humidity sensors 16320 may be positioned outside the mattress, such as below the bottom of the mattress. Additionally or alternatively, one or more humidity sensors 1632 may be mounted at a desired location on the mattress (e.g., the bottom of the mattress). Additionally or alternatively, one or more humidity sensors 1632 may be positioned in the airflow path between the fan 1610 and the airflow pad 1606.

[0377] [An exemplary bed in a bedroom setting] Figure 38 shows an exemplary environment 1200 including a bed 1202 that communicates with several devices in and around the home. In the illustrated example, the bed 1202 includes a pump 1204 for controlling the air pressure in two air chambers 1206a and 1206b (as described herein with respect to the air chambers). The pump 1204 further includes a circuit for controlling the inflation and deflation functions performed by the pump 1204. The circuit is further programmed to detect fluctuations in the air pressure of the air chambers 1206a and 1206b, and uses these detected fluctuations to identify the presence of user 1208 in the bed, user 1208's sleep state, user 1208's movements, and user 1208's bio-characteristic signals such as heart rate and respiratory rate. In the illustrated example, the pump 1204 is located within the support structure of the bed 1202, and a control circuit 1234 for controlling the pump 1204 is integrated with the pump 1204. In some implementations, the control circuit 1234 is physically separate from the pump 1204 and communicates with the pump 1204 wirelessly or via a wired connection. In some implementations, the pump 1204 and / or the control circuit 1234 are located outside the bed 1202. In some implementations, various control functions can be performed by systems located in various physical locations. For example, the circuit for controlling the operation of the pump 1204 may be located inside the pump casing of the pump 1204, while the control circuit 1234 for performing other functions related to the bed 1202 may be located inside another part of the bed 1202 or outside the bed 1202. As another example, the control circuit 1234 located inside the pump 1204 may communicate with a remote control circuit 1234 via a LAN or WAN (e.g., the Internet). As yet another example, the control circuit 1234 may be contained within the air chamber controller 1302 in Figure 34.

[0378] In some implementations, one or more devices other than, or in addition to, pump 1204 and control circuit 1234 may be used to identify the user's presence, sleep state, movement, and biocharacteristic signals in the bed. For example, bed 1202 may include a second pump in addition to pump 1204, and each of the two pumps may be connected to one of the air chambers 1206a and 1206b, respectively. For example, pump 1204 may be in fluid communication with air chamber 1206b and control the expansion and contraction of air chamber 1206b, and may detect user signals of a user located on air chamber 1206b, such as presence, sleep state, movement, and biocharacteristic signals. On the other hand, the second pump may be in fluid communication with air chamber 1206a and control the expansion and contraction of air chamber 1206a, and may also detect user signals of a user located on air chamber 1206a.

[0379] Additionally, bed 1202 may include airflow pads 1250a, 1250b (as described herein with respect to airflow pads). Bed 1202 includes an air controller 1252 for controlling airflow into and out of the airflow pads 1250a, 1250b, as described herein. The air controller 1252 may be located together with the pump 1204 or the control circuit 1234. In another example, the air controller 1252 may be located away from the pump 1204 and / or the control circuit 1234. In yet another example, the air controller 1252 may be contained within the airflow pad controller 1602 in Figure 37.

[0380] Furthermore, the bed 1202 may include foot warming pads 1260a, 1260b (as described herein with respect to foot warming pads). For example, the foot warming pad 1260 may be configured similarly to the foot heating element 1504 or heating unit 824 described herein. Alternatively or additionally, the foot warming pad 1260 may consist of an airflow pad 1250 and associated components. The bed 1202 includes a foot warming control circuit 1262 for controlling the temperature of the foot warming pads 1260a, 1260b. The foot warming controller 1262 may be located together with the pump 1204, the control circuit 1234, and / or the air controller 1252. In another example, the foot warming controller 1262 may be located separately from the pump 1204, the control circuit 1234, and / or the air controller 1252. In yet another example, the foot warming controller 1262 may be contained within the foot warming controller 1502 in Figure 36.

[0381] Alternatively or additionally, the bed 1202 may include one or more pressure-sensitive pads or pressure-sensitive surface portions that are operable to detect movement, including the presence of a user, user movement, breathing, and heart rate. For example, a first pressure-sensitive pad may be incorporated into the surface of the bed 1202 on the left portion of the bed 1202 where a first user normally sleeps, and a second pressure-sensitive pad may be incorporated into the surface of the bed 1202 on the right portion of the bed 1202 where a second user normally sleeps. The movement detected by the one or more pressure-sensitive pads or pressure-sensitive surface portions may be used by the control circuit 1234 to identify the user's sleep state, presence in the bed, or biocharacteristic signals.

[0382] In some implementations, information detected by the bed (e.g., motion information) is processed by the control circuit 1234 (e.g., a control circuit 1234 integrated with the pump 1204) and provided to one or more user devices, such as user device 1210, and presented to user 1208 or other users. In the example shown in Figure 38, user device 1210 is a tablet device. However, in some implementations, user device 1210 may be a personal computer, a smartphone, a smart TV (e.g., TV 1212), or another user device capable of wired or wireless communication with the control circuit 1234. User device 1210 may communicate with the control circuit 1234 of bed 1202 via a network or via direct point-to-point communication. For example, the control circuit 1234 may be connected to a LAN (e.g., via a Wi-Fi router) and may communicate with user device 1210 via the LAN. In another example, both the control circuit 1234 and user device 1210 may be connected to the Internet and may communicate via the Internet. For example, the control circuit 1234 may connect to the internet via a WiFi router, and the user device 1210 may connect to the internet via communication with a cellular communication system. As another example, the control circuit 1234 may communicate directly with the user device 1210 via a wireless communication protocol such as Bluetooth. As yet another example, the control circuit 1234 may communicate with the user device 1210 via a wireless communication protocol such as ZigBee, Z-Wave, or other wireless communication protocols suitable for the application. As yet another example, the control circuit 1234 may communicate with the user device 1210 via a wired connection such as a USB connector or other wired connection suitable for the application.

[0383] The user device 1210 may display various information and statistics related to sleep or user 1208's interaction with bed 1202. For example, the user interface displayed by the user device 1210 may present information including the amount of sleep user 1208 has over a certain period (e.g., one night, one week, one month), the amount of deep sleep, the ratio of deep sleep to restless sleep, the time elapsed between user 1208 getting into bed and falling asleep, the total time spent in bed 1202 over a given period, user 1208's heart rate over a certain period, user 1208's respiratory rate over a certain period, or other information related to user interaction with bed 1202 by user 1208 or one or more other users of bed 1202. In some implementations, information from multiple users may be presented to the user device 1210, for example, information from a first user located on air chamber 1206a may be presented together with information from a second user located on air chamber 1206b. In some implementations, the information presented on the user device 1210 may change depending on the user's age. For example, the information presented on the user device 1210 may evolve with the user's age, and different information may be presented on the user device 1210 as the user ages from child to adult.

[0384] User device 1210 may also be used as an interface for the control circuit 1234 of bed 1202 to allow user 1208 to input information. Information input by user 1208 may be used by the control circuit 1234 to provide better information to the user or to various control signals for controlling the functions of bed 1202 or other devices. For example, user 1208 may input information such as weight, height, and age, and the control circuit 1234 may use this information to provide the user with a comparison of the user's tracked sleep information with the sleep information of other people with similar weight, height, and / or age. As another example, user 1208 may use user device 1210 as an interface to control the air pressure of air chambers 1206a, 1206b, to control various reclining or tilting positions of bed 1202, to control the temperature of one or more surface temperature control devices of bed 1202, or to allow the control circuit 1234 to generate control signals for other devices (as described in more detail below).

[0385] In some implementations, the control circuit 1234 of the bed 1202 (for example, the control circuit 1234 integrated within the pump 1204) may communicate with other devices or systems in addition to, or instead of, the user device 1210. For example, the control circuit 1234 may communicate with the television 1212, the lighting system 1214, the thermostat 1216, the security system 1218, or other household appliances such as the oven 1222, the coffee maker 1224, the lamp 1226, and the night light 1228. Other examples of devices and / or systems that the control circuit 1234 may communicate with include a system for controlling the blinds 1230, one or more devices for detecting or controlling the state of one or more doors 1232 (e.g., detecting whether a door is open or not, detecting whether a door is locked or not, or automatically locking a door), and a system for controlling the garage door 1220 (e.g., a control circuit 1234 integrated with a garage door opener to identify the open / closed state of the garage door 1220 and cause the garage door opener to open or close the garage door 1220). Communication between the control circuit 1234 of the bed 1202 and other devices may occur via a network (e.g., LAN or the Internet) or as point-to-point communication (e.g., Bluetooth, wireless communication, or wired connection). In some implementations, the control circuits 1234 of different beds 1202 may communicate with different sets of devices. For example, a kids' bed may not communicate with and / or control the same devices as an adult bed. In some embodiments, the bed 1202 may evolve with the user's age such that the control circuit 1234 of the bed 1202 communicates with different devices as a function of the user's age.

[0386] The control circuit 1234 may receive information and inputs from other devices / systems and may use such received information and inputs to control the operation of the bed 1202 or other devices. For example, the control circuit 1234 may receive information from a thermostat 1216 indicating the current ambient temperature of the house or room in which the bed 1202 is located. The control circuit 1234 may use such received information (along with other information) to determine whether to raise or lower the temperature of all or part of the surface of the bed 1202. The control circuit 1234 may then instruct the heating or cooling mechanism of the bed 1202 (e.g., the foot warming system and / or airflow system described herein) to raise or lower the surface temperature of the bed 1202. For example, user 1208 may indicate a desired sleep temperature of 74 degrees Fahrenheit, while a second user of the bed 1202 may indicate a desired sleep temperature of 72 degrees Fahrenheit. The thermostat 1216 may indicate to the control circuit 1234 that the current temperature in the bedroom is 72 degrees Fahrenheit. The control circuit 1234 may identify that the user 1208 has indicated a desired sleep temperature of 74 degrees Fahrenheit and may send a control signal to a heating device on the user side of the bed (e.g., a foot warming pad and / or airflow pad as described herein) to raise the temperature of a portion of the surface of the bed 1202 (e.g., the foot or middle portion). It is positioned to raise the temperature of the user 1208's sleeping surface to the desired temperature.

[0387] The control circuit 1234 may also generate control signals to control other devices and propagate such signals to those other devices. In some implementations, the control signals are generated based on information collected by the control circuit 1234, including information about user interactions with the bed 1202 by user 1208 and / or one or more other users. In some implementations, information collected from one or more other devices other than the bed 1202 is used when generating control signals. For example, when generating control signals for various devices that communicate with the control circuit 1234 of the bed 1202, information about environmental occurrences (e.g., ambient temperature, ambient noise level, ambient light level, etc.), time, year, day of the week, or other information may be used. For example, information about the time may be combined with information about user 1208's movement and presence in the bed to generate control signals for the lighting system 1214. In some implementations, instead of providing control signals to one or more other devices, or in addition to doing so, the control circuit 1234 may transmit collected information (e.g., information related to user movement, presence in bed, sleep state, or user 1208's bio-characteristic signals) to one or more other devices, allowing those devices to utilize the collected information when generating control signals. For example, the control circuit 1234 of bed 1202 may provide a central controller (not shown) with information regarding user interaction with bed 1202 by user 1208. The central controller may utilize the provided information to generate control signals for various devices, including bed 1202.

[0388] Continuing with reference to Figure 38, the control circuit 1234 of bed 1202 may generate control signals to control the operation of other devices in response to information collected by the control circuit 1234, including the presence of user 1208 in bed, user 1208's sleep state, and other factors, and may transmit such control signals to the other devices. For example, the control circuit 1234 integrated with the pump 1204 may detect features of the bed 1202 mattress, such as an increase in pressure in the air chamber 1206b, and use this detected increase in air pressure to determine that user 1208 is on bed 1202. In some implementations, the control circuit 1234 may identify user 1208's heart rate or respiratory rate to determine that the increase in pressure is due to a person sitting, lying, or resting on bed 1202, rather than an inanimate object (such as a suitcase) being placed on bed 1202. In some implementations, information indicating a user's presence in bed is combined with other information to identify a possible current or future state of user 1208. For example, detection of a user's presence in bed at 11:00 AM might indicate that the user is sitting in bed (e.g., tying shoelaces or reading a book) and not yet planning to sleep. On the other hand, detection of a user's presence in bed at 10:00 PM might indicate that user 1208 is in bed and intends to sleep soon. As another example, if control circuit 1234 detects that user 1208 left bed 1202 at 6:30 a.m. (for example, indicating that user 1208 woke up for the day), and then detects user 1208's presence in bed at 7:30 a.m., control circuit 1234 may use (understand) this information not as an indication that user 1208 intends to stay in bed 1202 for an extended period, but rather as an indication that the newly detected user's presence in bed is likely temporary (for example, while user 1208 is tying their shoelaces before going to work).

[0389] In some implementations, the control circuit 1234 may use the collected information (including information related to user interaction with bed 1202 by user 1208, environmental information, time information, and input received from user) to identify user 1208's usage patterns. For example, the control circuit 1234 may use information collected over a period of time indicating user 1208's presence in bed and sleep state to identify the user's sleep patterns. For example, based on information indicating the user's presence collected over a week and user 1208's biometrics, the control circuit 1234 may identify that user 1208 generally goes to bed between 9:30 p.m. and 10:00 p.m., generally falls asleep between 10:00 p.m. and 11:00 p.m., and generally wakes up between 6:30 a.m. and 6:45 a.m. The control circuit 1234 may use a user identification pattern to better process and identify user interactions between user 1208 and bed 1202.

[0390] For example, given the bed presence, sleep, and wake patterns of user 1208 in the above example, if it is detected that user 1208 is in bed at 12:00 p.m., the control circuit 1234 may determine that the user's presence in bed is merely temporary and use this determination to generate a different control signal than one that would be gener...
