Description

Background Art

[0001] In various situations, it is desirable to releasably secure an object (which may also be referred to herein as a "payload") to a fixture. The fixture can be a stationary object, a non-stationary object, or yet another object.

[0002] For example, a cargo carrier is an example of a fixture. A cargo carrier is also known as a roof box, ski box or rack, cargo box, rooftop box, car top carrier, bike rack, surfboard rack, etc., and is a portable storage container or device that can be fixed to the top of an automobile or other vehicle as needed. Such a cargo carrier can be fixed to structural elements such as vehicle mounting brackets, roof racks, side rails, crossbars, etc. These structural elements are typically integral components permanently fixed to the roof of the vehicle.

[0003] One problem encountered in the art is that the roofs of many different vehicle models are significantly different in shape, size, and profile. Thus, some cargo carriers may be suitable only for a particular vehicle model. Universal cargo carriers are available, but their applications may still be limited to some different vehicle models in some cases.

[0004] Many vehicles do not have permanently fixed structural elements. Glass tops and / or glass sunroofs are becoming increasingly popular in the automotive industry. Furthermore, new vehicles, especially sports cars, tend to move away from including permanently fixed structural elements. Thus, most commercially available cargo carriers are not suitable for use in vehicles without permanently fixed structural elements.

[0005] In other situations, an object needs to be fixed to a fixture in a releasable manner. For example, an aerial drone or the like (an exemplary fixture) is designed to deliver and release a load (an exemplary payload releasably fixed to the aerial drone). However, the releasable fixing means employed by the drone for delivering a load or other object is, in itself, a very complex mechanical device.

[0006] As another example, robotics employs various types of robotic devices configured to releasably fix and manipulate an object. For example, a robotic arm (an exemplary fixture) can releasably fix and manipulate an object during a manufacturing process. Consider an object that is manipulated to a specific position and / or orientation for a welding process of welding a releasably fixed object to another object. When the welding process is completed, the robotic arm releases the welded object. Here, the releasable fixing means employed by the robotic arm to releasably fix the welding object is, in itself, a very complex mechanical device.

[0007] Another exemplary example occurs in surveillance technology, where an image capture device (camera) and / or microphone is fixed to some fixture for a certain period, such as weeks, months, or even years. Non-limiting examples of fixtures include walls, building structures, vehicles, etc. Permanently fixing a camera or other surveillance device to a fixed structure may not be desirable as the device mounting structure may require damage to the fixed structure, such as bolt holes or screw holes.

[0008] In application examples where an object is releasably fixed to another object, theft prevention is highly desired. Further, safety standards may be applicable, in which case the possibility of accidental release of the fixed object needs to be minimized according to the applicable safety standards.

[0009] Accordingly, there is a need for improved methods, devices, and systems for semi-permanently releasably securing an object while maintaining any required safety standards and / or deterring theft, in the technical field of temporarily or semi-permanently releasably securing an object. SUMMARY OF THE INVENTION

[0010] Multiple embodiments of an active object attachment system use one or more vacuum attachment modules to secure an object to the surface of a fixture. Each vacuum attachment module includes at least one vacuum pump controllably coupled to a microcontroller, a vacuum cup fluidly coupled to the at least one vacuum pump, and a transceiver that receives a command corresponding to either a vacuum cup activation signal or a vacuum cup release signal.

Embodiments for Carrying Out the Invention

[0019] Figure 1 is a top view of an active object attachment system 100 configured to fix a cargo carrier (not shown), preferably using a plurality of vacuum attachment modules 102. For example, the vacuum attachment module 102 can fix an object such as a cargo carrier to the roof 104 of a vehicle.

[0020] Each vacuum attachment module 102 includes a vacuum cup 106 and a vacuum control unit 108. The vacuum cup 106 is disposed outside the main body member on the side opposite to the cover member 402 (Figure 4). In the non-limiting exemplary embodiment of Figure 1, the active object attachment system 100 is coupled to a cargo carrier (not shown) using suitable fastening means. Suitable fasteners can include snaps, buttons, straps, belts with buckles, hook-and-loop fasteners, zippers, etc. In other embodiments, the fixture of the active object attachment system 100 and the vacuum attachment module 102 can be manufactured as an integrated unitary system.

[0021] The active object attachment system 100 can be used to releasably attach any object to any fixture. For example, the fixture can be an aerial drone for package delivery, and the object can be a payload that is delivered and released to a target location by the aerial drone.

[0022] When the vacuum attachment module 102 is activated in response to receiving a vacuum cup activation signal from the vacuum control device 110, the vacuum control unit 108 operates the pump to generate a vacuum of at least a predetermined vacuum level (negative atmospheric pressure) within the vacuum cup 106. The vacuum cup activation signal can be generated by various vacuum control devices 110 depending on a particular embodiment of the active object attachment system 100 that is used to releasably attach an object, also referred to herein as a payload. Accordingly, a plurality of vacuum attachment modules 102 can be used to cooperatively attach a payload in a releasable manner to the surface of a fixture (e.g., the rooftop 104 of the illustrated vehicle). Each vacuum attachment module 102 can independently maintain a target vacuum level or range within its respective vacuum cup 106, so that the payload can be fixed for any period of time. That is, the microcontroller 216 activates the vacuum pump in response to the sensed vacuum pressure becoming greater than a first predetermined vacuum pressure or in response to the sensed vacuum pressure becoming less than a second predetermined vacuum pressure to maintain a predetermined vacuum pressure between the surface and the vacuum cup 106. Accordingly, the object (i.e., the payload) can be semi-permanently fixed to the surface of the fixture.

[0023] In the non-limiting exemplary use case shown in FIG. 1, when a user desires to use a cargo carrier (not shown), the active object attachment system 100 can be semi-permanently or temporarily releasably (removably) fixed to the vehicle roof 104. When the user is not using the cargo carrier, the active object attachment system 100 can be released from the vehicle roof 104, and the active object attachment system 100 can be removed from the vehicle roof 104. The plurality of vacuum attachment modules 102 are released (return the pressure level to at least atmospheric pressure) in response to receiving a vacuum cup release signal from the vacuum control device 110. In a preferred embodiment, one of the plurality of vacuum attachment modules 102 is the vacuum control device 110. In other embodiments, the vacuum control device 110 can be another electronic device.

[0024] The vacuum control device 110 can generate a vacuum cup actuation signal and / or a vacuum cup release signal in response to a signal received from a handheld (portable) communication device (such as a smartphone), a remote device that can be part of a fixture and / or responsible for controlling the fixture, another device that receives input instructions from a user (such as a switch, button, or other suitable manual controller, but not limited thereto), and / or another device such as a manual controller.

[0025] One unexpected advantage provided by embodiments of the active object attachment system 100 is that the suction force exerted by each suction cup 106 of the vacuum attachment module 102 can be controlled to be above a predefined value defined by safety considerations, thus improving the safety when using a cargo carrier for a vehicle or other removably fixed object. Further, the embodiments provide anti-theft protection because the suction force exerted by the vacuum attachment module 102 provides a stronger fixing means for fixing the load to the fixture than conventional fixing means. Additionally, the active object attachment system 100 can be equipped with an anti-tampering function and cannot be easily removed by a thief.

[0026] The systems and methods of the present disclosure for securing a load to a fixture using an active object attachment system 100 will be better understood by considering the following detailed description in conjunction with the drawings. The detailed description and the drawings provide examples of various inventions described herein. Those skilled in the art will understand that the embodiments of the present disclosure can be changed, modified, and altered without departing from the scope of the inventions described herein. Many variations are possible depending on different uses and design considerations, but for the sake of brevity, not all possible variations will be individually described in the following detailed description.

[0027] In the following detailed description, various embodiments of systems and methods for releasably securing a load to a fixture using an active object attachment system 100 are provided. Related features within an embodiment can be the same, similar, or dissimilar in different embodiments. For the sake of brevity, duplicate descriptions of related features are not provided in each embodiment.

The reader should understand that a given feature need not be identical or similar to a particular depiction of a related feature of a given drawing or embodiment.

[0028] Unless otherwise specified, the following definitions apply throughout this specification.

[0029] "Substantially" means conforming more or less to a particular dimension, range, shape, concept, or other aspect (feature) modified by the term. A function or component need not conform exactly. For example, an object that is "substantially cylindrical" means that the object resembles a cylinder but may have one or more deviations (differences) from a true cylinder.

[0030] The terms "comprise", "include" and "have" (and their conjugations) are used interchangeably and mean including but not necessarily limited to the thing(s) (object), and are open-ended terms not intended to exclude additional elements or method steps not explicitly recited.

[0031] Terms such as "first", "second" and "third" are used to distinguish or identify various members of a group, etc., and are not intended to indicate a sequential, chronological or numerical limitation.

[0032] "Coupled" means connected, either directly or indirectly through intervening components, either permanently or removably. "Fixed" means connected directly without intervening components.

[0033] "Communicatively coupled" means that an electronic device is communicatively connected to another electronic device, either directly or indirectly through a communication network, using a wireless or wired-based connector. "Controllably coupled" means that an electronic device controls the operation of another electronic device.

[0034] Figure 2 is a block diagram of one embodiment of the vacuum attachment module 102 and shows selected exemplary electronic components. A non-limiting exemplary vacuum attachment module 102 includes a power supply 202, a vacuum pump 204 (optional with venturi), a pressure sensor 206, one or more optional environmental sensors 208, a transceiver 210, an optional user interface 212, an optional indicator light 214, a processor system 216, and a memory 218. The memory 218 includes portions for storing a transceiver module 220, a user interface module 222, a vacuum pump and check valve module 224, and a monitoring module 226. In some embodiments, the transceiver module 220, the user interface module 222, the vacuum pump and check valve module 224, and the monitoring module 226 can be integrated together and / or integrated with other logic. In other embodiments, some or all of these memories and other data manipulation functions can be provided by using a remote server or other electronic device suitably connected to a client device via the Internet or other means. Other embodiments of the vacuum attachment module 102 can include some of the foregoing components or can omit some. Further, additional components not described herein can be included in alternative embodiments.

[0035] The power supply 202 is preferably a battery-based power supply that supplies power to the processor system 216, the vacuum pump 204, and other selected components. A replaceable battery and / or a rechargeable battery can be used. Preferably, the power obtained from the power supply is sufficient to operate the vacuum attachment module 102 for at least a predetermined semi-permanent period, which period can be several weeks, several months, or more than one year. In alternative embodiments, any suitable power source, such as (but not limited to) a generator, solar power generation, magnetic power generation, etc., can be used.

[0036] In a preferred embodiment, the processor system 216 monitors the power currently available from the power source 202. When the power drops below a threshold, a warning notification can be communicated from the processor system 216 to the vacuum control device 110, to the user's portable handheld electronic device, and / or to another system such as a vehicle control system. In some embodiments, power management recommendations can be made to the user so as to manage the use of the vacuum attachment module 102. For example, if the power source is supplied by a battery and a low battery state occurs, or if a low battery state can be predicted to occur in the near future, the user can be notified of the remaining power or battery life. The user can then choose to replace one or more batteries of the power source 202 and / or, if the battery is rechargeable, recharge the battery.

[0037] The vacuum pump 204 controllably coupled to the processor system 216 is an electric vacuum pump that establishes a vacuum (a pressure lower than the actual atmospheric pressure) sufficient to secure the vacuum cup 10 to the surface of the load. The load is removably secured. An optional venturi can be used with the vacuum pump 204. The pressure differential across the venturi, if used, improves the efficiency of the vacuum pump 204. The processor system 216 that executes the vacuum pump and the check valve module 224 controls the operation of the vacuum pump 204. In response to receiving a vacuum cup activation signal, the vacuum pump 204 is activated to generate a vacuum, and the vacuum removably secures the vacuum attachment module 102 to the load. The processor system 216 activates the vacuum pump 204 to release the vacuum in response to receiving a vacuum cup release signal, thereby releasing the load from the vacuum attachment module 102. It is intended that any suitable vacuum pump 202 currently known or developed in the future be included within the scope of the present disclosure and be protected by the appended claims.

[0038] A suitable embodiment comprises two or more vacuum pumps 204a, 204b. A port 408 fluidly couples the vacuum pumps 204a, 204b to the internal cavity of the vacuum cup 106. A check valve 410 (FIG. 4) can be used to maintain the vacuum pressure established within the vacuum cup 106. The check valve 410 has a cracking pressure corresponding to a predetermined vacuum pressure within the vacuum chamber such that a predetermined vacuum pressure is maintained within the vacuum cup 106 when the vacuum cup attachment system 100 is fixed to the surface of an object. The check valve 410 can be a mechanical check valve that uses a spring or the like to operate the valve, or an active check valve that uses electricity to operate the check valve 410. Control of the electronic check valve 410 can be managed by a processor system 216 (FIG. 2) that executes a vacuum pump and check valve module 224.

[0039] The plurality of vacuum pumps 204 provides reliability in the event that a single vacuum pump 204 fails. In various embodiments, any desired number of vacuum pumps 204 can be used. Also, the plurality of vacuum pumps 204 can be used to generate a more powerful vacuum in cooperation.

[0040] An optional pressure sensor 206 monitors the pressure within the vacuum cup 106. The pressure sensor 206 is communicatively coupled to a processor system 216 (also referred to herein as a microcontroller). The microcontroller 216, which executes a monitoring module 226, monitors the sensed vacuum pressure within the vacuum cup 106 in real time. Once a vacuum is established to releasably secure a load to the vacuum cup 106, the processor system 216, which executes a vacuum pump and check valve module 224, can further operate the vacuum pump 204 in response to the monitored pressure within the vacuum cup 106 falling below a predefined threshold. Accordingly, the vacuum pressure within each of the plurality of vacuum cups 106 can be controlled to any desired predetermined pressure value or pressure range.

[0041] For example, the vacuum in the plurality of vacuum cups 106 can vary according to altitude. When the user drives the vehicle to a higher altitude or to a lower altitude, the processor system 216 can operate the vacuum pump 204 to adjust and / or maintain the vacuum pressure to a desired target pressure value or target pressure range according to the change in altitude. For example, the sensor 206 can sense the current vacuum pressure. The processor system 216 can compare the current vacuum pressure with one of a plurality of predefined thresholds. A command is communicated to the vacuum pump 204 to increase or decrease the vacuum pressure. In this way, the change in the vacuum pressure is executed so that the current vacuum pressure remains at some predefined value (or range).

[0042] As another example, the vacuum pressure can be varied as a function of vehicle speed. Here, a higher vacuum pressure can be generated as the vehicle speed increases to ensure that the vacuum attachment module 102 does not come off the vehicle roof 104 due to the increased wind caused by the increasing vehicle speed. A speed sensor (not shown) such as a speedometer provides the current vehicle speed information to the processor system 216. The processor system 216 compares the current vacuum pressure with a predefined vacuum pressure associated with the vehicle speed. A command is communicated to the vacuum pump 204 to increase or decrease the vacuum pressure to a new vacuum pressure corresponding to the current vehicle speed. In this way, the change in the vacuum pressure is executed so that the current vacuum pressure value (or range) is appropriate for the current speed.

[0043] In one embodiment, a pressure sensor 206 is disposed within the vacuum attachment module 102 to sense the vacuum pressure. The pressure sensor 206 can be an internal component of the vacuum cup 106 or a separate component disposed at the vacuum port 408 (FIG. 4) of the vacuum pump 204. Alternatively or additionally, the pressure sensor 120 can be an integrated component of the vacuum pump 204.

[0044] In various embodiments, a predetermined vacuum pressure or pressure range can be maintained within the vacuum cup 106. For example, a slow leak between the edge of the vacuum cup 106 and the surface of the payload that is releasably fixed thereto may result in a loss of vacuum pressure. The sensor 206 can sense the decreasing current vacuum pressure due to such slow leak. The processor system 216 compares the current vacuum pressure to one of a plurality of predefined thresholds. A command is communicated to the vacuum pump 204 to increase or decrease the vacuum pressure. In this way, the change of the vacuum pressure is executed so that the current vacuum pressure remains at some predefined value (or range). Accordingly, the vacuum control unit 108 can automatically activate when the vacuum pressure goes outside a predetermined threshold or threshold range and can re-establish the vacuum pressure. Some embodiments may employ an electronically actuated check valve 410 that can be activated and / or adjusted to facilitate maintaining the desired vacuum pressure.

[0045] As another example, changing environmental conditions such as temperature and / or altitude can change the vacuum pressure, whereby the control unit 108 can automatically activate in response to the vacuum pressure dropping or rising beyond a predetermined threshold or threshold range and can re-establish the vacuum pressure. Here, the sensor 206 can sense the current vacuum pressure changing due to the changing environmental conditions. The processor system 216 can compare the current vacuum pressure to one of a plurality of predefined thresholds. A command is communicated to the vacuum pump 204 to increase or decrease the vacuum pressure. In this way, the change of the vacuum pressure is executed so that the current vacuum pressure remains at some predefined value (or range).

[0046] The environmental sensor 208 can be used to monitor external environmental conditions such as humidity, rainfall, wind speed, ambient pressure, temperature, etc. Based on the sensed environmental conditions, the processor system 216 can execute the vacuum pump and check valve module 224 to change the predefined minimum vacuum pressure so that it is appropriate for environmental conditions where the vacuum pressure maintained in the vacuum cup 106 changes. For example, when the altitude increases and the ambient pressure decreases, or when the altitude decreases and the ambient pressure increases, the actual vacuum pressure can be automatically adjusted by the vacuum control unit 108 and / or the vacuum control device 110 to maintain the predefined minimum vacuum pressure and / or maximum vacuum pressure within the vacuum cup 106 or the vacuum attachment module 102. Alternatively, some embodiments can maintain a predetermined pressure difference between the vacuum within the vacuum cup 106 and the current ambient pressure.

[0047] The transceiver 210 is configured to wirelessly receive and / or transmit radio frequency (RF) communication signals to other transceivers 210 within other vacuum attachment modules 102 and / or vacuum control devices 110. In such embodiments, the wireless communication transceiver 210 can be a low-power communication system such as a short-range communication system. An exemplary short-range wireless communication is Bluetooth. Any suitable low-power and / or short-range wireless communication system known currently or developed in the future can be used in various embodiments. Since multiple vacuum attachment modules 102 and / or vacuum control devices 110 are in proximity to each other, a low-power short-range wireless communication system is suitable.

[0048] Alternatively or additionally, other wireless-based communication networks and / or hybrid communication networks may be communicatively coupled to transceiver 210. Exemplary communication systems include, but are not limited to, cellular phone systems, Wi-Fi systems, satellite systems, radio frequency (RF) systems, and / or telephone systems. In such embodiments, transceiver 210 may be communicatively coupled to a wireless communication system. Accordingly, transceiver 210 enables communication between the remote electronic device and vacuum attachment module 102 and / or vacuum control device 110. In some applications, transceiver 210 is communicatively coupled to a user's portable handheld electronic device such as a smartphone, notebook, etc. In such embodiments, the user may use the portable handheld electronic device and / or another control system to operate vacuum attachment module 102 and / or vacuum control device 110 (initiate a vacuum cup activation signal and / or a vacuum cup release signal), and / or monitor the performance of vacuum attachment module 102 and / or vacuum control device 110.

[0049] In one embodiment, a processor system 216 that executes transceiver module 220 receives and / or transmits communications from other vacuum attachment modules 102, vacuum control devices 110, or other remote electronic devices. As disclosed herein, vacuum attachment module 102 activates vacuum pump 204 to establish a vacuum within vacuum cup 106 in response to transceiver 210 receiving a vacuum cup activation signal from vacuum control device 110, one of the other vacuum attachment modules 102, and / or another remote electronic device. Conversely, processor system 216 that executes transceiver module 220 may deactivate vacuum pump 204 to terminate the vacuum within vacuum cup 106 in response to transceiver 210 receiving a vacuum cup release signal from vacuum control device 110, one of the other vacuum attachment modules 102, and / or another remote electronic device.

[0050] A selective user interface 212 may be provided to enable manual control of the vacuum attachment module 102 by a user. Buttons, switches, or other controllers may enable the user to manually activate the vacuum control unit 108. A processor system 216 that executes the user interface module 222 may operate the vacuum pump 204 to establish and / or release a vacuum in the vacuum cup 106 based on a control signal generated by the user interface 212 in response to a manual operation of the user interface 212 by the user.

[0051] For example, after a load is first fixed to a fixture, the user may want to reposition and / or reorient the fixed load. For example, the position and / or orientation of a camera (object or load) fixed to a surface (fixture) may be changed to adjust the field of view of an image captured by the camera. The user may manually deactivate one or more vacuum attachment modules 102 to perform the adjustment and then reactivate (activate) those vacuum attachment modules 102 to re-establish the vacuum in the vacuum cup 106.

[0052] External to the vacuum attachment module 102 and / or the vacuum control device 110, one or more selectable indicator lights (display lights) 214 may be provided to indicate the operating state of the device and / or system. For example, the processor system 216 may cause the indicator light 214 to emit light when the vacuum attachment module 102 is functioning properly. Alternatively or additionally, when the vacuum attachment module 102 is not operating properly, another colored light and / or another indicator light may emit light. Thus, the user can visually determine whether the vacuum attachment module 102 is operating properly based on the visible output of the indicator light 214. In some embodiments, the indicator light 214 may be remotely located. In this case, the indicator light 214 may be communicatively coupled to another remote transceiver. A light control signal generated by the processor system 216 may be communicated from the transceiver 210 to the other transceiver. Thereafter, the light control signal may be received by the remote indicator light 214.

[0053] Returning to FIG. 1, the active object attachment system 100 is generally described in the context of attaching a cargo carrier or other object to the roof top 104 of a vehicle. The active object attachment system 100 includes a plurality of vacuum attachment modules 102 that releasably secure an object to a stationary object, such as an exemplary cargo carrier to the roof 104. Here, when the plurality of vacuum attachment modules 102 are secured to the cargo carrier prior to use, the stationary object can be the cargo carrier. For clarity, the cargo carrier is not shown in FIG. 1. In practice, each of the plurality of vacuum attachment modules 102 can be secured to the cargo carrier or an intervening structure using appropriate fastening means prior to the active object attachment system 100 being used. In such an exemplary embodiment, the roof top 104 of the vehicle is the object to be secured to the stationary object (cargo carrier) using the plurality of vacuum attachment modules 102 under the control of the vacuum control device 110.

[0054] The vacuum control device 110 is preferably disposed in the immediate vicinity of the plurality of vacuum attachment modules 102. The vacuum control device 110 can be disposed at any convenient location. For example, the vacuum control device 110 can be fixed to the underside of the cargo carrier, but is not limited to this embodiment. Alternatively, the vacuum control device 110 can be fixed to the vehicle rooftop 104, can be held within the passenger compartment of the vehicle, can be held with the user (at the user's hand), or can be held within the cargo carrier. In some embodiments, a selected one of the plurality of vacuum attachment modules 102 also functions as the vacuum control device 110.

[0055] In a non-limiting embodiment configured to fix the cargo carrier to the vehicle rooftop 104, a selective outer seal 112 can be used to form a seal between a portion of the surface of a fixture such as the cargo carrier and the vehicle roof 104. The outer seal 112 is a suitable semi-rigid or flexible material that generally conforms to the shape and size of the active object attachment system 100 and / or the outer perimeter of the cargo carrier. In a preferred embodiment, the outer seal 112 is manufactured from neoprene, rubber, rubber foam, etc., with a suitable thickness (height) sufficient to form a cavity between the lower surface of the cargo carrier 102 and the vehicle roof. Accordingly, the plurality of vacuum attachment modules 102 of the active object attachment system 100 fit between the lower surface of a fixture (e.g., the cargo carrier) 102 and an object to be releasably fixed (here, the vehicle roof 104) and are surrounded by the outer seal 112.

[0056] In non-limiting exemplary embodiments, a suitable adhesive may be used to secure the outer seal 112 to a fixture and / or an object to which it is releasably secured. In other embodiments, the seal 112 may be secured using other means such as hardware. In a preferred embodiment, the outer seal 112 forms a continuous ring of material surrounding the active object attachment system 100. In other embodiments, a discontinuous ring of material is used for the outer seal. Alternatively or additionally, a strip of material disposed at selected locations may be used to form the outer seal 112.

[0057] In some embodiments, the outer seal 112 is not secured to a fixture, to the vehicle roof 104, or to an object to which it is releasably secured. Rather, after the active object attachment system 100 is positioned and secured to a fixture at a predetermined location, the outer seal 112 is disposed around a plurality of vacuum attachment modules 102 of the active object attachment system 100. Thereafter, the object to which it is releasably secured is disposed at a predetermined location on the outer seal 112.

[0058] In various embodiments employing a selective outer seal 112, in response to activation of the active object attachment system 100, air is drawn from the plurality of vacuum attachment modules 102. When a vacuum is created within the vacuum cup 106, the flexible vacuum cup 106 is partially folded and its height is reduced. Since the fixture is fixed to the active object attachment system 100, when the vacuum cup 106 is folded downward, the surface of the releasably fixed object and the surface of the fixture are drawn together. Thus, the outer seal 112 is compressed and a friction seal is formed between the surface of the releasably fixed object and the surface of the fixture. Since the vacuum cup 106 is present within the cavity formed by the compressed outer seal 112, the vacuum cup 106 is protected from forces generated by weather and / or moving air. That is, since the outer seal 112 is made of a flexible and airtight material such as neoprene, it serves to keep the weather and moving air away from the vacuum cup 106 to avoid disturbing the vacuum cup 106. By protecting the seal of the vacuum cup 106 against the vehicle roof, the power requirements of the vacuum pump 110 can be reduced. Further, the reliability of the vacuum cup 106 at the leading edge, which may experience the greatest "lift force" during vehicle movement, can be increased.

[0059] In a preferred embodiment, the outer seal 112 is initially provided as a sheet of material that can be cut by the user to the desired shape and size. Alternatively or additionally, a pre-cut outer seal 112 that has been cut based on the dimensions of the active object attachment system 100, the fixture, and / or the object to be releasably fixed, may be provided.

[0060] In practice, the user places the active object mounting system 100 on the vehicle roof 104 and adjusts the position of the cargo carrier (fixed object) so that the plurality of vacuum mounting modules 102 are arranged at desired positions on the vehicle roof 104 (when the vacuum mounting modules 102 are already fixed to the fixed object, here the cargo carrier). Next, the user activates the active object mounting system 100, operates the vacuum control device 110 to communicate a vacuum cup activation signal to the plurality of vacuum mounting modules 102, and operates the internal vacuum pumps of each of the plurality of vacuum mounting modules 102 to generate a vacuum. The generated vacuum sucks air from below each vacuum cup 106 at that time to generate a further vacuum. The generated vacuum seals each vacuum cup 106 of the vacuum mounting module 102 to the upper surface of the vehicle roof 104 as long as the vacuum is maintained. In this way, the cargo carrier is fixed to the vehicle roof.

[0061] Preferably, when the vehicle has a glass top, the plurality of vacuum cups 106 are arranged on the glass top. A relatively strong seal is generated between each vacuum cup 106 (and the intervening outer seal) and the smooth glass surface of the vehicle's glass top. Alternatively, the plurality of vacuum mounting modules 102 can be fixed to the painted surface of a metal vehicle roof. Further, the active object mounting system 100 can be used to fix other types of objects that are releasably fixed to other surfaces of the vehicle, such as the trunk, side, or other surfaces of the vehicle.

[0062] Depending on the specific application of the present invention, it is understood that the optional outer seal 112 disposed between the fixture and the object (load) can be used with one or more vacuum attachment modules 102 disposed within the outer seal 112. For example, a camera (here, the fixture, to which one or more vacuum attachment modules 102 are fixed) can be fixed to a building wall or a vehicle surface (here, the fixture to which the camera is releasably fixed) using the optional outer seal 112. Alternatively, the camera can be releasably fixed to a building wall or a vehicle surface without using the outer seal 112.

[0063] Figure 3 is a perspective top view of the vacuum attachment module 102 with the corresponding cover member 402 (Figure 4) removed to expose the interior of the vacuum control unit 108. Figure 4 is a side cross-sectional view of the vacuum attachment module with a non-limiting exemplary cover member. The vacuum control unit 108 is preferably defined by a rigid or semi-rigid body member 302 (such as, but not limited to, a monocoque body), which defines a cavity that encompasses various components within the vacuum control unit 108. Some embodiments can be formed as a monocoque body. The body member 302 protects the various components within the body cavity from damage. In a non-limiting exemplary embodiment, the monocoque body member 302 defines a monocoque cavity that fixes and protects the components of the vacuum control unit 108, and the vacuum cup is coupled to the monocoque body member 302.

[0064] The vacuum cup 106 is preferably manufactured from a flexible or semi-flexible material that is air-impermeable. In various embodiments, the vacuum cup 106 is permanently fixed to the body member 302 in an airtight manner. Alternatively, the body member 302 and the vacuum cup 106 are formed as an integral part.

[0065] The exemplary embodiments illustrated in FIGS. 3 and 4 include one or more optional manual release tabs 304. The manual release tab 304 is a member that protrudes outwardly on the outside of the vacuum cup 106. The tab 304 can be gripped by a user to lift the bottom of the flexible vacuum cup 106 from the surface of the load after the vacuum has been released. When the user grips and pulls the manual release tab 304, ambient air flows into the interior of the vacuum cup 106, releasing the remaining vacuum pressure and releasing the vacuum attachment module 102 from the load. In various embodiments, any desired number of manual release tabs 304 can be provided at any location.

[0066] A plurality of openings 306 (holes) are shown as being fabricated in the body member 302 of the vacuum control unit 108. These openings 306 are used to secure the cover member 402 to the upper surface of the body member 302. The openings 306 can be threaded holes that receive threaded bolts or screws 404 (FIG. 4) that pass through corresponding openings 406 in the cover member 402. When the bolts or screws 404 are threaded and tightened into place, the cover member 402 is secured to the upper portion of the body member 302. Alternatively, the openings 306 may not be threaded, and nuts and bolts 404 can be used to secure the cover member 402 to the body member 302 of the vacuum control unit 108. Alternatively or additionally, other fastening means such as screws, clamps, magnets, adhesives, etc. can also be used to secure the cover member 402 to the upper portion of the vacuum cup 106. In some embodiments, the cover member 402 can be secured to or made a part of the body member 302 of the vacuum control unit 108 during manufacture.

[0067] The non-limiting exemplary cover member 402 includes an outward protruding member 412 that protrudes outward from the outer surface of the cover member 402. A selective opening 414 may be disposed through the outward protruding member 412. Bolts or screws 404 are used to fix the cover member 402 to a fixture. In this non-limiting exemplary embodiment, the height of the outward protruding member 412 is high enough to allow access to the opening 406 when the bolts or screws 404 are used to fix the cover member 402 to the upper part of the vacuum control unit 108.

[0068] An unexpected advantage provided by the cover member 402 is that the outer surface of the cover member 402 can be permanently (or semi-permanently) fixed to the surface of the fixture, or releasably fixed, before the use of the vacuum attachment module 102. For example, the cover member 402 can be screwed, bolted, or adhered onto the surface of a building or a vehicle (fixture). At that time, the upper part of the vacuum control unit 108 and the cover member 402 are fixed together, and the vacuum attachment module 102 is fixed to the surface of the fixture.

[0069] Figures 5A through 5D show various embodiments of a cover plate 402 that can be fixed to the upper part of the vacuum control unit 108 (Figures 3 and 4). In Figure 5A, one or more openings 502 penetrate the outward protruding member 412a. In this embodiment, bolts or screws 404 (Figure 4) can be used to fix the cover member 402 to the fixture at any convenient time. That is, before or after the cover member 402 is fixed to the upper part of the vacuum control unit 108, the fixture can be fixed to the cover member 402.

[0070] For example, the fixture can be an image capture device (camera) or other mechanical device. The active object attachment system 100 can employ one or more vacuum attachment modules 102 that are fixed to the surface of the vehicle (here the object of interest). When a user desires to acquire image information (still images and / or videos), the user can easily fix the camera (here the fixture) to the outward protruding member 412a using bolts or screws 404 through the opening 502. After use, the user can remove the camera for storage.

[0071] In FIG. 5B, a threaded portion (thread) 504 is disposed on the outer surface of the outward protruding member 412b. The exemplary camera or other object described above can include a threaded hole having a threaded portion corresponding to the threaded portion 504. The camera or other object can be easily fixed to the cover member 402 at any time and can be easily removed from the cover member 402.

[0072] In FIG. 5C, a tie-down (binding) opening 506 extends through the outward protruding member 412c. A strap, rope, bungee cord, or other securing material can be passed through the tie-down opening 506 and can fix any structure (here the fixture) to the cover member 402 at any time. Alternatively or additionally, a hook or the like fixed to a strap, rope, bungee cord, or other securing material can be hooked into the tie-down opening at any time.

[0073] FIG. 5C also shows another exemplary securing means that can be used to fix the cover member 402 to the top of the vacuum control unit 108. Here, a threaded portion (thread) 508 is disposed along the outer edge of the cover member 402. A corresponding threaded portion is disposed along the inner surface of the opening at the top of the vacuum control unit 108 (not shown). When a user desires to fix the cover member 402 to the top of the vacuum control unit 108, the user can easily screw the cover member 402 onto the top of the vacuum control unit 108 (or vice versa) at any time.

[0074] FIG. 5D shows an embodiment of a cover member 402 without an outwardly projecting member 412. In this exemplary embodiment, a threaded opening 510 is disposed on the cover member 402. The threaded opening 510 can penetrate through the cover member 402 and can extend downwardly so as to pass through only a part of the cover member 402. After the cover member 402 is fixed to the upper part of the vacuum control unit 108, a fixture having a corresponding outwardly projecting threaded member can be screwed onto the cover member 402.

[0075] After considering the present disclosure, those skilled in the art will understand that various types of fixing means can be used to fix the cover member 402 to the upper part of the vacuum control unit 108 without departing from the novel features of the present invention. Similarly, those skilled in the art will understand that various types of fixing means can be used to fix the cover member 402 to any type of fixture without departing from the novel features of the present invention. All such embodiments are within the scope of the present disclosure and are intended to be protected by the appended claims.

[0076] FIG. 6 is a block diagram of a vacuum attachment module control system 602 employing a designated vacuum control device 110 for controlling a plurality of vacuum attachment modules 102. Each of the vacuum attachment modules 102 (slave devices) is controllably coupled to a vacuum control device 110 (master device). Preferably, a master / slave control system enables the vacuum control device 110 to generate a vacuum cup activation signal and a vacuum cup release signal using an appropriate short-range or wired-based communication signal and transmit them to the plurality of vacuum attachment modules 102. In some embodiments, one of the selected vacuum attachment modules 102 is designated as the vacuum control device 110.

[0077] In addition, the vacuum control device 110 is configured to receive information from a plurality of vacuum attachment modules 102. Operating state information can be communicated to the vacuum control device 110. For example, if one of the vacuum attachment modules 102 fails or begins to lose vacuum pressure, the vacuum control unit 108 can be notified of the failure and / or vacuum pressure loss by the particular vacuum attachment module 102. Optionally, the vacuum control device 110 can increase the vacuum pressure within the remaining vacuum attachment modules 102 to compensate for the failed vacuum attachment module 102. As another non-limiting example, the vacuum pressure of one or more of the vacuum attachment modules 102 can be selectively changed by the vacuum control device 110.

[0078] Optionally, the vacuum control device 110 can be communicatively coupled to a remote electronic device 602. The remote electronic device 602 can communicate with the vacuum control device 110 using an appropriate wireless communication signal 606 format, such as a short-range communication signal and / or a cellular phone communication signal. In response to receiving a command from the remote electronic device 604, the vacuum control device 110 can generate and transmit a vacuum cup activation signal and a vacuum cup release signal. In some embodiments, a wired-based communication format can be used. Additionally or alternatively, the vacuum control device 110 can communicate operating state information and / or vacuum pressure information to the remote electronic device 602. Accordingly, the user can be aware of the operating state of the active object attachment system 100. If the remote electronic device 602 is a smartphone or the like, an application that facilitates communication between the smartphone and the vacuum control device 110 can be installed on the smartphone.

[0079] FIG. 7 is a block diagram of a vacuum attachment module control system 702 employing a mesh network 704, where a plurality of vacuum attachment modules 102 cooperate to control the operation of an active object attachment system 100. Here, the individual vacuum attachment modules 102 are communicatively coupled together. Each of the vacuum attachment modules 102 communicates information such as its operating state and / or vacuum pressure to each of the other vacuum attachment modules 102. Thus, the plurality of vacuum attachment modules 102 operate in cooperation (collaborate) to secure an object. Some embodiments may employ an artificial intelligence algorithm to more effectively control the operation of the active object attachment system 100.

[0080] Optionally, one or more of the vacuum attachment modules 102 may be communicatively coupled to a remote electronic device 602 using a suitable wireless communication signal 606 format such as a short-range communication signal and / or a cellular phone communication signal. When one or more of the vacuum attachment modules 102 receive a command from the remote electronic device 604, the vacuum attachment module 102 responsible for the reception may communicate a vacuum cup activation signal and a vacuum cup release signal to the other vacuum attachment modules 102. In some embodiments, a wired-based communication format may be used. Additionally or alternatively, the said one or more of the vacuum attachment modules 102 may communicate operating state information and / or vacuum pressure information to the remote electronic device 602. Thus, the user may grasp the operating state of the active object attachment system 100. When the remote electronic device 602 is a smartphone or the like, an app that facilitates communication between the smartphone and the vacuum attachment module 102 may be installed on the smartphone.

[0081] After considering the present disclosure, those skilled in the art will understand that the plurality of vacuum attachment modules 102 can be implemented using any suitable mono Internet of Things (IoT) technology. All such IoT embodiments currently known or developed in the future are intended to be within the scope of the present disclosure and protected by the appended claims.

[0082] It should be emphasized that the foregoing embodiments of the active object attachment system 100 are merely possible examples of the implementation of the present invention. Many variations and modifications can be made to the foregoing embodiments. All such modifications and changes are intended to be within the scope of the present disclosure and protected by the appended claims.

[0083] Furthermore, the foregoing disclosure encompasses a plurality of distinguishable inventions having independent utility.
