[0004] It is an object of the present invention to provide improved devices, kits, systems, and methods that facilitate the transmission of data collected by devices, particularly personal care devices. In particular, it is an object of the present invention to provide devices, kits, systems, and methods that enable device-related data to be transmitted over a desired wireless communication standard (such as a member of the IEEE 802.11 family of standards) without (while still allowing) the device itself to have the communications circuitry required for that particular communications standard. It is also an object of the present invention to provide such devices that can be manufactured in an efficient manner.

[0005] According to an embodiment of the present invention, a switched mode power supply charger device operative to power and recharge a battery of an appliance, particularly a personal care appliance, comprises a communications circuit operative to transmit appliance-related data.

[0006] The switched mode power supply charger device may include a power plug configured to mate with a power outlet and having several compartments, with the communication circuitry located in one of the compartments.

DETAILED DESCRIPTION OF THE INVENTION

[0014] The embodiments will be described with reference to the drawings. Features of the embodiments may be combined with each other unless otherwise specified.

[0015] Although embodiments are described in connection with power supply devices for personal care appliances and in connection with systems, kits, and methods that may include personal care appliances, the technology is not limited thereto. For purposes of illustration, the switched mode power supply charger device may operate to power a household appliance, and the household appliance may be, but need not be, a personal care appliance. Kitchen appliances are examples of such appliances.

[0016] FIELD OF THE INVENTION Embodiments of the present invention relate to power supply devices and related kits, systems, and methods. The switched mode power supply charger device has communication capabilities. The switched mode power supply charger device is operative to transmit equipment related data.

[0017] As used herein, the phrase "power source" or "power supply" encompasses the supply of electrical energy to a device for live use of the device (e.g., for using the supplied power to drive electromechanical actuators) and also the supply of electrical energy to a device for charging a battery that may optionally be present.

[0018] The communication capabilities of the switched mode power supply charger device may be used not only in connection with equipment to which the switched mode power supply charger device can supply electrical energy, but also in connection with equipment that may require a different type of electrical switched mode power supply charger device and / or equipment that may not require electrical power, for example, because it does not include electromechanical actuators.

[0019] The "equipment related data" transmitted by the switched-mode power supply charger device may be data relating to equipment that the switched-mode power supply charger device is mechanically engaged to provide power to, data relating to equipment that the switched-mode power supply charger device is mechanically engageable to provide power to but that is not engaged to during the data transmission, and / or data relating to equipment that the switched-mode power supply charger device is not mechanically engageable to provide power to.

[0020] According to one embodiment, a switched-mode power supply charger device for an appliance includes a power cable having a connector for reversibly releasably engaging with the appliance and a power plug configured to engage with a power outlet. The power plug includes a housing having a first compartment and a second compartment adjacent to the first compartment. The power plug includes a converter disposed in the first compartment, the converter having a converter input and a converter output galvanically isolated from the converter input and electrically connected to the power cable. The power plug includes a communication circuit disposed in the second compartment and electrically connected to the converter output, the communication circuit including a wireless interface circuit.

[0021] The integration of communications circuitry into the switched mode power supply charger device allows device-related data to be transmitted, for example, to a wide area network (WAN) without requiring (while still allowing) an interface for communication with the WAN to be present in the device itself, and without requiring a user to communicatively couple a terminal device (such as a cellular phone, wearable, tablet, or portable or stationary computer) to the device for transmission of the device-related data.

[0022] The two-section configuration of the power plug and the integration of the communication circuitry into the power plug facilitates manufacturing. The communication circuitry may be mounted external to the first section, with power conversion occurring within the first section, which provides a power level that does not pose a safety hazard to the user. The first section can have a configuration that allows it to be used without the communication circuitry, streamlining the manufacturing of power plugs that include the communication circuitry.

[0023] The two-compartment configuration of the power plug also aids in recyclability and / or maintenance. For illustrative purposes, the communications circuitry may continue to be used in association with a different converter when the converter of the switched mode power supply charger device is no longer fully operational. For further illustrative purposes, new communications circuitry may be installed on a switched mode power supply charger device that includes an operational converter when the original communications circuitry is no longer fully operational.

[0024] The switched-mode power supply charger device may be a switched-mode power supply charger device for a personal care appliance. This facilitates the use of the switched-mode power supply charger device in connection with the personal care appliance. Users tend to have a variety of personal care appliances for daily use, and not all (or even any of them) are equipped with the desired wireless data communication capability (e.g., communication with a server connected to a WAN). The switched-mode power supply charger device provides this communication capability.

[0025] The switched-mode power supply charger device may be a switched-mode power supply charger device for a household appliance, such as a home appliance. This facilitates use of the switched-mode power supply charger device in association with the household appliance. Users tend to have a variety of household appliances for daily use, and not all (or even any of them) are equipped with the desired wireless data communication capability (e.g., communication with a server connected to a WAN). The switched-mode power supply charger device provides this communication capability.

[0026] The first compartment may be sealed against water intrusion. The first compartment may have a waterproof rating of, for example, IPX4, IPX5, IPX6, or higher. The communications circuitry may be located downstream of the converter housed in the first compartment along a power transmission path from the power outlet connector pin to the device. The second compartment may have a waterproof rating lower than that of the first compartment because voltage downconversion has already occurred upstream of the communications circuitry.

[0027] The first compartment may be watertight.

[0028] The switched mode power supply charger device can operate to pass the electrical energy output by the converter through the communications circuitry to the power cable. This configuration facilitates manufacturing of the power supply device. The communications circuitry may be added to an autonomous power plug component that provides voltage down-conversion, is sealed against water ingress, and serves as a first compartment of the power supply device that is integrated with the communications circuitry into the power supply device.

[0029] The connector may include electrical contacts that abut corresponding contacts on the device.

[0030] The connector may include inductive and / or capacitive power transfer arrangements for contactless power transfer to the device.

[0031] The communications circuitry may be operable to be powered by the power output by the converter, and the power used by the communications circuitry may be derived from the power passing through the communications circuitry to the device.

[0032] The housing may include a wall separating the first and second compartments. This configuration facilitates manufacturing of the switched mode power supply charger device by providing a mount for the communication circuitry.

[0033] The housing may include an end cap. The end cap and the wall may define a second compartment. This configuration facilitates manufacturing of the power device. The communication circuitry and end cap may be added to an autonomous power plug component that provides voltage down-conversion, is sealed against water ingress, and functions as a first compartment within the power device. Thus, to add wireless functionality, only a second compartment needs to be added to the power charger device. By providing a cap on this second compartment, only a module is added to the autonomous power plug device, ensuring a modular design.

[0034] The wall may include a passageway through which at least one conductor extends from the interior of the first compartment to the interior of the second compartment. The passageway may be sealed against water ingress into the first compartment. This configuration facilitates manufacturing of the switched mode power supply charger device while ensuring that all components of the device that may be exposed to the power supply voltage are sealed against water ingress. Optionally, a second compartment, added to the first housing compartment by, for example, a housing cap, is less sealed against water ingress.

[0035] The power plug may include a sealing arrangement that seals the passageway against water ingress into the first compartment. This arrangement facilitates manufacturing of the switched mode power supply charger device while ensuring that all components of the device that may be exposed to the power supply voltage are sealed against water ingress.

[0036] The power plug may comprise at least one sheath into which the at least one conductor is received and which is integral with or sealingly attached to a wall. This configuration facilitates manufacture of the switched mode power supply charger device while ensuring that all components of the device that may be exposed to the power supply voltage are sealed against the ingress of water.

[0037] The communications circuitry may include a power input connected to at least one conductor, thereby allowing power destined for the device to pass through the communications circuitry while the communications circuitry is powered by a power output from the circuitry contained within the first compartment.

[0038] The communications circuitry may include a power output electrically connected to a conductor of the power cable, thereby allowing power destined for the device to pass through the communications circuitry while the communications circuitry is powered by a power output from the circuitry contained within the first compartment.

[0039] The power plug may include a number of connector pins for engaging with a power outlet, each of the number of connector pins extending along a first direction, and a wall extending transversely and optionally perpendicularly to the first direction, thereby allowing a communication circuit to be conveniently disposed toward an end face of the power plug and facilitating electronic coupling of the communication circuit with a user interface.

[0040] The wireless interface circuitry may operate to transmit equipment-related data, the communication of which to a computer or server connected to a wide area network (such as the Internet) being enabled by the power supply device without the equipment itself needing to have a communications interface that enables it to communicate with, for example, an IEEE 802.11 compliant access point.

[0041] Device-related data may include device operational data. Device operational data may include information regarding time, aggregate time, and / or frequency of use. Device operational data may include information regarding parameters measured by the device (such as voltage, current, battery capacity, battery charge cycle information, and / or temperature). Such information may be useful for providing assistance to a user, for example, by providing information regarding component wear, suggestions regarding device use, or other useful user instructions. Such information may also be useful for maintenance purposes.

[0042] The device-related data may include device status data. The device status data may include information regarding the status of at least one component of the device. The device status data may include or be derived from parameters measured by the device, such as battery health status, the status of components that are subject to wear during use of the device (such as the outer blade or cutting blade of a hair-cutting device), or other status information indicative of the status of the device or its components. Such information is useful for providing assistance to the user, for example, by providing information regarding component wear, suggestions regarding device use, or other useful user instructions. Such information may also be useful for maintenance purposes.

[0043] The equipment-related data may include first equipment-related data associated with a first equipment having an equipment connector operable to matingly engage with a connector of the power device.

[0044] The equipment-related data may include second equipment-related data associated with a second equipment that does not have an equipment connector operable to matingly engage with the connector of the power device.

[0045] The second equipment-related data may relate to equipment that does not have an electromechanical actuator.

[0046] Alternatively or additionally, the communications circuitry may operate to receive data and, possibly after processing, provide the data to one or more personal care devices using wired or wireless communications.

[0047] The communications circuitry may comprise at least one further communications interface circuit distinct from the wireless interface circuit for collecting equipment-related data, the at least one further communications interface circuit enabling the switched mode power supply charger device to collect equipment-related data for transmission via the wireless interface circuit without requiring the equipment itself to have a respective wireless interface circuit.

[0048] The at least one further communications interface circuit may comprise a wired communications circuit. The wired communications circuit may operate to collect device-related data via first and second conductors of a power cable through which power is supplied. Alternatively or additionally, the at least one further communications interface circuit may comprise a further wireless interface circuit different from the wireless interface circuit. The at least one further communications interface circuit enables the switched-mode power supply charger device to collect device-related data for transmission via the interface, and the device itself does not (but still can) need to be operational for data transmission via the wireless interface circuit through which the switched-mode power supply charger device transmits the device-related data.

[0049] The at least one further communication interface circuit may comprise both a wired communication circuit and a further wireless interface circuit different from the wireless interface circuit. Thus, the switched mode power supply charger device may comprise at least three different communication interface circuits and may provide versatility in collecting equipment related data.

[0050] The communications circuitry may be operative to transmit data received by the wireless interface circuitry to the personal care device, thereby allowing data for configuring the personal care device, firmware or software updates for the personal care device, or other data to be provided to the personal care device via the power device without the personal care device itself needing to have an interface that allows the device to access a repository in which the configuration data, firmware, or software updates are stored.

[0051] The communication circuitry may operate for one-way or two-way communication with the personal care appliance.

[0052] One-way or two-way communication with the personal care appliance may be established via at least one further communication interface. The two-way communication capability may be used by the power supply device to provide data for configuring the personal care appliance, update data for the personal care appliance, or other data to the personal care appliance.

[0053] The switched mode power supply charger device may include a memory, which may be located in a second compartment, facilitating temporary storage of device-related data prior to transmission.

[0054] The memory may comprise persistent memory, which may have access information stored therein that enables the communication circuitry to communicate via an access point and / or transmit device-related data to a server or computer.

[0055] The persistent memory may store security-related data therein, and the communications circuitry is operative to use the security-related data for data obfuscation, encryption, and / or authentication when transmitting device-related data.

[0056] The power plug may comprise a user interface. The user interface may allow information related to the operation of the power device (e.g., its communication status or configuration status) to be output. The user interface may allow the switched mode power supply charger device to be configured to communicate with, for example, an access point. This may be done via communication with a user terminal, which need only be selectively established to configure the access point, and not necessarily for subsequent transmission of equipment-related data.

[0057] The user interface may comprise at least one actuation element for operating the communication circuitry to enter the configuration mode. The actuation element may comprise a physical actuation element. The actuation element may comprise a button, which may be a soft button or a hard button.

[0058] The user interface may include at least one status indicator operative to output status information related to the communication circuit, and optionally, the at least one status indicator may include several light segments. The status indicator(s) may include one or more light-emitting elements. The status indicator(s) may include one or more LEDs. The status indicator(s) may include one or more LED-based light segments that may be arranged partially or entirely around the circumference of the end face of the power plug. This allows several status indicators to be integrated into a small area.

[0059] The converter may be an AC / DC converter, which facilitates the use of a switch mode power supply charger device to obtain operating power for equipment from the voltage of a power outlet.

[0064] The device may be operable to communicate with the communication circuitry of the switched mode power supply charger device using a second communication standard (such as wired communication via conductors in the power cable, Bluetooth, or BLE) that is different from the communication standard (such as IEEE 802.11 a, b, g, n, ac, ax, and / or ad) supported by the wireless interface circuitry of the communication circuitry of the power device, thereby allowing an inexpensive communication chipset to be used for communication between the device and the power device, eliminating the need for, for example, a chipset for communicating with an access point within the device.

[0065] The device may be configured to be unable to communicate according to a communication standard supported by the wireless interface circuit of the communication circuit of the power supply device (e.g., IEEE 802.11 a, b, g, n, ac, ax, and / or ad, etc.), which allows an inexpensive communication chipset to be used for communication between the device and the power supply device, and, for example, eliminates the need to provide a chipset for communicating with an access point within the device.

[0066] The kit may further comprise a wireless local area network (WLAN) access point. The communications circuitry may be operable to transmit equipment-related data to a remote computing device via the WLAN access point. This enables the switched mode power supply charger device to operate as a hub that collects, optionally processes and / or aggregates, and then transmits equipment-related data via the access point.

[0067] The kit may further comprise a user terminal, wherein the communications circuitry is operable to receive from the user terminal configuration information for the air interface circuitry needed for subsequent transmission of equipment-related data to a remote computing device via an access point of a wireless local area network (WLAN).

The switched-mode power supply charger device 50 may operate to transmit the device-related data via an interface corresponding to transmission of the device-related data to a server 44 or computer 44 connected to a wide area network (WAN) 43, such as the Internet. The server 44 or computer 44 may be provided on the cloud. The switched-mode power supply charger device 50 may operate to transmit the device-related data, for example, via a WLAN interface (e.g., compliant with or compatible with IEEE 802.11, such as IEEE 802.11-2012 or IEEE 802.11-2016).

[0104] The equipment-related data may, but need not, relate to equipment being powered by switched-mode power supply charger device 50. The switched-mode power supply charger device may operate to collect and transmit equipment-related data for equipment (such as personal care equipment) that cannot be electrically connected to switched-mode power supply charger device 50 to receive power therefrom, that is not currently electrically connected to switched-mode power supply charger device 50 to receive power therefrom, and / or that does not require any wired connection to switched-mode power supply charger device 50 to receive power therefrom.

[0105] The device-related data may include data retrieved by the switched-mode power supply charger device 50 from the device 20, 30 via a wired or wireless communication channel and / or data collected by the switched-mode power supply charger device 50 while the switched-mode power supply charger device 50 is connected to the device.

[0106] The operation and construction of the switched mode power supply charger device 50 is described in more detail below.

[0107] The switched mode power supply charger device 50 includes a power cable 54 having a connector 55 for reversibly releasably engaging with the device 20, 30. The switched mode power supply charger device 50 includes a power plug 51 configured to engage with the power outlet 41. The power plug 51 includes a housing. As described in more detail below, the housing may include a first compartment that houses a converter operative to perform voltage down-conversion. The housing may also include a second compartment, distinct from the first compartment, in which communication circuitry is located. Power supplied to the device 20, 30 may pass through the communication circuitry within the second compartment. The first compartment may be sealed against water ingress.

[0108] The power plug 51 has connector pins 52, 53 for mating with the power outlet 41 and thereby electrically connecting to a power source.

[0109] The switched mode power supply charger device 50 may operate as follows.

[0110] Switch Mode Power Supply Charger Device 50 Configuration This is an operational step that does not need to be performed with every use. Configuration may be performed only once and / or when the access information for access point 42 changes and / or when the access information for the user-specific protected storage space in server or computer 44 changes. This configuration is optional and may be omitted, for example, if the relevant communication data has already been provisioned into switched-mode power supply charger device 50 when provided to the user.

[0111] In the configuration mode, the communications circuitry of switched-mode power supply charger device 50 can receive information necessary to transmit device-related data to server or computer 44 via access point 42. Alternatively or additionally, the communications circuitry of switched-mode power supply charger device can receive information necessary to access a user-specific protected storage space within server or computer 44. This information can be persistently stored within switched-mode power supply charger device 50 and can be accessed when switched-mode power supply charger device 50 transmits device-related data.

[0112] The switched-mode power supply charger device 50 may enter the configuration mode in response to a physical input action performed on an operating element of the switched-mode power supply charger device 50 .

[0113] Configuration information (which may include the name or other identifier of access point 42, a key for communicating with access point 42, and user identifier and / or passcode information for accessing a protected, user-specific storage device connected to WAN 43) may be received by switched-mode power supply charger device 50 from user terminal 45. User terminal 45 may provide an interface that allows a user to enter alphanumeric information to configure switched-mode power supply charger device 50 for its intended communication to access point 42 and, optionally, server or computer 44. Switched-mode power supply charger device 50 may receive the configuration information from user terminal 45 and may persistently store the configuration information for later use in transmitting equipment-related data.

[0114] Acquisition of device-related data During field use of the switched-mode power supply charger device 50, the switched-mode power supply charger device 50 can acquire equipment-related data. This may include receiving information from each of the devices 20, 30 via a wired or wireless communication link. Alternatively or additionally, (part of) the equipment-related data may be generated by the power supply device 50. To illustrate, during one or more charging cycles, the switched-mode power supply charger device 50 can determine the charging characteristics (such as charging current and voltage) of one or more rechargeable batteries of the devices 20, 30, which may be useful for establishing information regarding the battery condition (such as battery health).

[0115] Device-related data may include device operational data. Device operational data may include information regarding time, aggregate time, and / or frequency of use. Device operational data may include information regarding parameters measured by the device 20, 30 (such as voltage, current, battery capacity, battery charge cycle information, and / or temperature). Such information may be useful for providing assistance to the user, for example, by providing information regarding component wear, suggestions regarding device use, or other useful user instructions. Such information may also be useful for maintenance.

[0116] Alternatively or additionally, the device-related data may include device status data. The device status data may include information regarding the status of at least one component of the device 20, 30. The device status data may include or be derived from parameters measured by the device 20, 30, such as the status of components that are subject to wear during use of the device (such as the outer blade or cutting blade of a hair-cutting device), or other status information indicative of the status of the device 20, 30 or its components. Such information may be useful for providing assistance to the user, for example, by providing information regarding component wear, suggestions regarding device use, or other useful user instructions. Such information may also be useful for maintenance purposes.

[0117] When the switched-mode power supply charger device 50 acquires device-related data, it may use a communication interface different from the wireless interface circuitry through which the switched-mode power supply charger device 50 transmits the device-related data. By way of example, the switched-mode power supply charger device 50 may have communication circuitry comprising a first communication chipset (e.g., a WiFi communication chip) or other circuitry operative to transmit the device-related data and a second communication chipset or other circuitry (e.g., a Bluetooth, Bluetooth Low Energy (BLE), or wired communication chip) operative to receive data from at least one of the device(s) 20, 30.

[0118] Equipment related data may be temporarily stored in the switched mode power supply charger device 50 .

[0119] Sending device-related data During field use of switched-mode power supply charger device 50, switched-mode power supply charger device 50 may transmit equipment-related data. Switched-mode power supply charger device 50 can begin transmitting equipment-related data in response to a trigger event (such as at least one of receiving new equipment-related data, expiry of a timer, connection of switched-mode power supply charger device 50 to power outlet 41 and optionally to an equipment), and optionally conditionally, can begin transmitting equipment-related data at time intervals that may be user-configurable when switched-mode power supply charger device 50 is engaged with power outlet 41 and an equipment.

[0120] Transmission of equipment related data by the switched mode power supply charger device 50 may occur in the following cases:

[0121] Transmitting the device-related data may include selectively establishing, via the communications circuitry, a communications connection for transmitting the device-related data. Configuration information that enables the switched-mode power supply charger device to establish the communications link 47 may be retrieved from memory integrated with the power supply device. Transmitting the device-related data may include selectively transmitting, via the communications circuitry, the device-related data to a computer or server 44 for storage. Access information that enables user-specific storage space to be accessed may be retrieved from memory integrated with the power supply device.

[0122] The communication circuitry of the switched mode power supply charger device may include wireless interface circuitry that enables equipment related data to be transmitted from the switched mode power supply charger device 50 to a remotely located computer or server 44 via an access point 42 (which may be a WLAN access point, particularly a WiFi access point) and a WAN 43.

[0123] Providing data to devices During field use of switched-mode power supply charger device 50, switched-mode power supply charger device 50 may optionally operate to provide data received via access point 42 or directly from user terminal 45 to one or more devices. Switched-mode power supply charger device 50 may operate to provide data for configuring devices, firmware or software updates for personal care devices, or other data to be transmitted to devices without requiring the device(s) to have an interface that allows the device(s) to access a repository where the data for configuring the devices, firmware or software updates for the personal care devices, or other data to be transmitted to the devices is stored or received.

[0124] In one example, the computer or server 44 can provide software or firmware updates to an appliance (such as a personal care appliance) and the switched mode power supply charger device 50 passes the data to the appliance.

[0125] In another example, the user terminal 45 can provide data to configure an appliance (such as a personal care appliance), and the switched-mode power supply charger device 50 passes the data to the appliance.

[0126] Access to device-related data The equipment-related data and / or additional information generated from the equipment-related data may be accessed by a user using a user terminal 45 (which may, but need not be, the same as the user terminal used when switched-mode power supply charger device 50 is configured to transmit data, for example, via access point 42). User terminal 45 may access the equipment-related data to, for example, reviewing the user's use of the device(s) based on device-related data (such as time spent shaving and / or brushing the user's teeth); receiving suggestions for the user's use of the device(s) 20, 30 based on the device-related data (such as suggestions for changing the device's operating mode); - receive advice on recommended maintenance actions (such as replacing replaceable components, for example, cutting blades or shaver blades or toothbrush devices) based on the device-related data; and / or Based on the equipment-related data, advice may be received regarding maintenance actions (such as replacing a battery) that should be carried out by a qualified person.

[0127] User terminal 45 can access the equipment-related data via server or computer 44 or using a direct communications link with the wireless interface circuitry of switched-mode power supply charger device 50. Switched-mode power supply charger device 50 is operable to provide the equipment-related data to user terminal 45 (e.g., via a direct wireless communications link between switched-mode power supply charger device 50 and user terminal 45).

[0128] The equipment-related data does not need to be accessed via a user terminal. By way of example, the equipment-related data may be selectively accessed by service personnel when performing maintenance operations on the equipment.

[0129] The methods disclosed herein may each include using the transmitted device-related data for maintenance and service purposes of the device(s).

[0130] 2 is a schematic partial view of the power device showing in more detail the power plug 51. The power plug 51 comprises a first compartment 61 and a second compartment 62 separated by a wall 65.

[0134] The enclosure 63 surrounding the first compartment 61 may be waterproof. By way of example, the enclosure 63 may comply with IPX4 or higher (e.g., as determined according to ISO 20653, DIN 40050-9, or IEC 60529). A passageway where the conductor 79 passes from the first compartment 61 through the wall 65 may be provided with a sealing arrangement 68. The sealing arrangement may be or may comprise a molding compound 68 applied to prevent the ingress of water into the first compartment 61.

[0135] The second compartment 62 houses communications circuitry 90.

[0143] The second compartment 62 is defined by an end cap 69, which may be engaged with the enclosure 63, for example, at wall 65. The connection between the end cap 69 and the enclosure 63 may be, but need not be, waterproof. The second compartment 62 may have a lower IPX rating (e.g., determined according to ISO 20653, DIN 40050-9, or IEC 60529) than the first compartment 61. The end cap 69 may be attached by ultrasonic welding 67, adhesive, or other attachment means.

[0144] The second compartment 62 may have a height 142 measured along a direction 141 from the surface of the wall 65 to a point on the outer surface of the end cap 69 that has a greatest distance from a plane defined by the surface of the wall 65 facing away from the converter 71. The height 142 may be less than 1 cm, less than 0.9 cm, less than 0.8 cm, less than 0.7 cm, less than 0.6 cm, or less than 0.5 cm.

[0145] The sealing arrangement 68 may be implemented in various forms. FIG. 3 shows an implementation in which the wall 65 includes a passage 81 through which at least one conductor 79 passes from the first compartment 61 to the second compartment 62. The sheath 82 may be attached to or integrally formed with the wall 65 and may extend into the second compartment 62. The sheath 82 may be formed as a conduit through which the conductors received in the respective conductor sheaths may be received in close abutting contact. The sheath 82 may have a resilience that seals against the conductors within the conductor sheaths. Alternatively or additionally, the sealing arrangement may be formed by a molding material 68 applied to seal the passage 81 against water intrusion.

[0148] The wireless interface circuitry 92 may include an antenna 92' operable to transmit, and optionally receive, in the 5 GHz and / or 2.4 GHz bands. The wireless interface circuitry 92 may be a communications chip or chipset for communicating in accordance with the IEEE 802.11 standard (e.g., compliant with IEEE 802.11-2012 or 802.11-19).

[0150] The memory 95 may be a non-volatile memory. The memory 95 is operable to store device-related data even during periods when the power plug 51 is not engaged with the power outlet 41.

[0151] The communication circuit 90 may have a power input 98 and a power output 97. The power input 98 may be connected to and receive power from the output of the converter 71. The power input 98 may be coupled to the low voltage side of the converter 71.

[0152] The communications circuitry 90 may have a power output 99. The power output 99 may be electrically connected to conductors extending within the power cable 54.

[0153] The communication circuitry 90 may have conductors 97 interconnecting a power input 98 and a power output. The conductors 97 may be implemented as conductive traces. In operation of the power supply device, power is transmitted by the conductors 97 from the converter 71 to an appliance mated to the connector 55.

[0154] The communications circuitry 90 may include a power supply circuitry 96. The power supply circuitry 96 may be connected to conductors 97 or may be connected to a power supply input 98. The power supply circuitry 96 is operable to provide power to the wireless interface circuitry 92, the control circuitry 91, and, if present, the user interface 100.

[0155] The communications circuitry 90 may include a user interface (UI) 100. The user interface 100 may be operable to output status information thereon. The user interface 100 may be operable to receive user input that causes the communications circuitry 90 to enter a configuration procedure that enables the communications circuitry 90 to be configured to communicate with, for example, the access point 42 and / or the computer or server 44. In response to actuation of an actuation element of the UI 100, the communications circuitry 90 may establish a communications link to a programming device (such as the terminal 45) separate from the power device, thereby enabling at least one of the parameters, addresses, keys, and / or identifiers to be configured, thereby enabling the communications circuitry 90 to transmit device-related data to the access point 42 and / or the computer or server 44.

The status indicators may be activated continuously or intermittently (e.g., blinking) to provide status information using the area available on the power plug. Control circuitry 91 may be operative to activate one or more of the status indicators to indicate one or more of the following: the switched mode power supply charger device is in a configuration mode in which it operates to be configured for communication with an access point 42 and / or a computer or server 44; the switched mode power supply charger device is in the process of establishing a communications link with an access point 42 and / or a computer or server 44; the switched mode power supply charger device has established a communications link with an access point 42 and / or a computer or server 44; The switched mode power supply charger device captures equipment related data (which may be implemented via the wireless interface circuit 92 or a communication interface different from the wireless interface circuit 92); -The switch mode power supply charger device transmits equipment related data.

[0159] Identical indicators 102-105 may be operated differently to indicate different statuses. For purposes of illustration, identical indicators 102-105 may be operated in two different modes (blinking mode and continuous mode) to indicate two different states. For purposes of illustration, one of the status indicators may be operated in a blinking mode to indicate that the switched-mode power supply charger device is in the process of establishing a communications link with access point 42 and / or computer or server 44, and may be operated in a continuous mode to indicate that the switched-mode power supply charger device has established a communications link with access point 42 and / or computer or server 44.

[0160] The switched-mode power supply charger device may capture equipment-related data from one or more equipment(s) (not necessarily limited to the equipment being powered).

The wireless interface circuit 92 may operate to provide one-way or two-way communications with the access point 42, enabling device-related data to be transmitted to a computer or server 44.

[0162] The further interface circuitry 93 may not be capable of establishing a communication link with the access point 42. The further interface circuitry 93 may be operable to communicate with one or more appliances via the power supply device to obtain appliance-related data.

[0163] The further interface circuit 93 may be implemented as a wireless communication circuit, but need not be so implemented. Two or more further interface circuits 93 may be provided, with at least one of the further interface circuits 93 being a wireless communication circuit operating according to a communications protocol different from that used by the wireless interface circuit 92. The switched mode power supply charger device may include both at least one further interface circuit 93 that is a wireless communication circuit operating according to a communications protocol different from that used by the wireless interface circuit 92, and a wired communications circuit that operates to collect equipment related data via conductors through which power is supplied to equipment in field use.

[0164] Further interface circuitry 93 may operate to receive data from a programming device, such as terminal device 45, that provides access information for communicating with access point 42 and / or computer or server 44. By way of example, when the switched-mode power supply charger device is set in a configuration mode (e.g., by activation of activation element 101), further interface circuitry 93 may receive access information for access point 42 (such as a WLAN name and key) and / or access information for a protected storage area within computer or server 44 (such as an identifier and / or passcode for a user-specific data repository area) from terminal device 45 or another device selectively communicatively coupled to communications circuitry 90 to configure communications circuitry 90.

[0165] The communications circuitry 90 may be operable to store the acquired device-related data in memory 95. The communications circuitry 90 may optionally be operable to process the data acquired from one or more devices before transmitting it as device-related data. By way of illustration, the communications circuitry 90 may be operable to aggregate data collected from one and the same device over an extended period of time before transmitting it as device-related data.

[0166] The communications circuitry 90 is operable to store in memory 95 access information for the access point 42 (such as the WLAN name and key) and / or access information for a protected storage area within the computer or server 44 (such as an identifier and / or passcode for a user-specific data repository area) for later use in transmitting device-related data.

[0167] The radio interface circuit 92 and the further interface circuit 93 may be implemented by different ICs, for example by different chips or chip sets.

[0168] 7 is a block diagram of a communications circuit 90 that may be used in a switched-mode power supply charger device according to one embodiment. The communications circuit 90 comprises a wireless interface circuit 92, a first further interface circuit 93, and a second further interface circuit 94. The wireless interface circuit 92, the first further interface circuit 93, and the second further interface circuit 94 may operate to provide communications capabilities using different data carriers (e.g., different frequencies and / or different mediums, such as wired and wireless). The wireless interface circuit 92 may operate to provide communications with an access point 42. The wireless interface circuit 92 may operate to provide one-way or two-way communications with the access point 42, enabling device-related data to be transmitted to a computer or server 44.

[0169] The first further interface circuit 93 and the second further interface circuit 94 may not be capable of establishing a communication link with the access point 42. The first further interface circuit 93 and the second further interface circuit 94 may be operative to communicate with one or more pieces of equipment in order to obtain equipment-related data by the power supply device. The first further interface circuit 93 and the second further interface circuit 94 may be complementary in the sense that one uses a wired communication technology (such as communication via conductors in a power cable through which power is supplied to equipment in field use) and the other uses a wireless communication technology (such as Bluetooth, Bluetooth Low Energy (BLE), or a machine-to-machine (M2M) communication protocol supported by cellular standards such as LTE or LTE-A).

[0170] In one implementation, the wireless interface circuitry 92 may operate to transmit data over a communications link with the access point 42 in accordance with IEEE 802.11 (e.g., 802.11-12 or 802.11-19) compliant technology. The first further interface circuitry 93 may operate to obtain equipment-related data by reading data from the equipment using communications over conductors in a power cable through which power is supplied to the equipment in field use. The second further interface circuitry 94 may operate to obtain equipment-related data by reading data from the equipment using a wireless communications technology other than IEEE 802.11 (such as Bluetooth, Bluetooth Low Energy (BLE), or machine-to-machine (M2M) communications protocols supported by cellular standards such as LTE or LTE-A).

[0171] The first further interface circuit 93 may be operable to receive data from a programming device, such as the terminal device 45, that provides access information for communicating with the access point 42 and / or the computer or server 44. By way of example, when the switched-mode power supply charger device is set in a configuration mode (e.g., by activation of the activation element 101), the further interface circuit 93 may receive access information for the access point 42 (such as a WLAN name and key) and / or access information for a protected storage area within the computer or server 44 (such as an identifier and / or passcode for a user-specific data repository area) from the terminal device 45 or another device selectively communicatively coupled to the communications circuit 90 to configure the communications circuit 90.

[0172] 8 is a flowchart of a method 110 that may be used to configure a switched-mode power supply charger device to transmit equipment-related data. Steps 111-113 of method 110 may selectively need to be performed only if any one of the following occurs: (i) an initial configuration of the switched-mode power supply charger device by a user; (ii) the name and / or key of access point 42 changes; and, optionally, (iii) the user's identifier and / or passcode on computer or server 44 changes.

[0173] In step 111, a user input is received at the power device UI 100. The user input may be a button actuation. The user input may cause the communications circuitry 90 to enter a configuration mode.

[0174] In step 112, the communications circuitry 90 establishes a communications connection with the user terminal device 45. The communications connection with the user terminal device 45 may be established using an interface circuit of the communications circuitry 90 (e.g., a Bluetooth or BLE chip) that is different from the interface circuit of the communications circuitry 90 used to transmit appliance-related data.

[0175] In step 113, configuration information is received by the switched-mode power supply charger device from the user terminal device 45 via the communications link established in step 112. The configuration information may include access information for the access point 42 (such as the WLAN name and key) and / or access information for a protected storage area within the computer or server 44 (such as an identifier and / or passcode for a user-specific data repository area). The configuration information may be stored persistently in memory 95 for subsequent use.

[0176] In step 114, the switched-mode power supply charger device may transmit equipment-related data over the wireless interface circuitry (e.g., in accordance with IEEE 802.11). The equipment-related data may include equipment-related data obtained before the configuration in steps 111-113 when the equipment-related data is determined by monitoring performed by the switched-mode power supply charger device itself (as in the case of battery health information) and / or when the equipment-related data is obtained over a wired or wireless interface different from that configured in steps 111-113. The equipment-related data may also include equipment-related data obtained after the configuration in steps 111-113.

[0177] The device-related data transmitted in step 114 may include device operational data. The device operational data may include information regarding time, aggregate time, and / or frequency of use. The device operational data may include information regarding parameters measured by the device (such as voltage, current, battery capacity, battery charge cycle information, and / or temperature). Such information may be useful for providing assistance to the user, for example, by providing information regarding component wear, suggestions regarding device use, or other useful user instructions. Such information may also be useful for maintenance purposes.

[0178] The device-related data transmitted in step 114 can include device status data. The device status data can include information regarding the status of at least one component of the device. The device status data can include or be derived from parameters measured by the device, such as battery health status, the status of a component that experiences wear during use of the device (such as an outer blade or cutting blade of a hair-cutting device), or other status information indicative of the status of the device or its components. Such information can be useful for providing assistance to a user, for example, by providing information regarding component wear, suggestions regarding device use, or other helpful user instructions. Such information can also be useful for maintenance purposes. The device-related data can include first device-related data associated with one or more devices having a device connector operable to mate and engage with a connector of the power device. The device-related data can include second device-related data associated with one or more other devices that do not have a device connector operable to mate and engage with a connector of the power device. Thus, the switched-mode power supply charger device may operate as a data aggregation and transmission hub for collecting and transmitting device-related data for various devices (such as various personal care or other home devices) without requiring the user's cell phone or computer to be involved in the data collection and transmission, which can be selectively used solely to configure the switched-mode power supply charger device for the respective home network and / or user.

[0179] Step 114 may be repeated. The repetition of step 114 may be triggered by a trigger event. The trigger event may be or include engagement of the switched-mode power supply charger device with a power outlet and / or appliance, expiration of a timer, or other criteria that may be permanently stored within the switched-mode power supply charger device or that may be configurable in steps 111-113.

Alternatively or additionally, the equipment-related data may relate to one or more second equipment not currently being powered by the power supply device. Communication between the second equipment(s) and communications circuitry 90 may be enabled by a battery of the second equipment(s).

[0183] The device-related data obtained in step 122 may include device operational data. The device operational data may include information regarding the time, aggregate time, and / or frequency of use of each first and / or second device. The device operational data may include information regarding parameters (such as voltage, current, battery capacity, battery charge cycle information, and / or temperature) measured by each first and / or second device(s), and is optionally buffered in each first and / or second device(s) and read by the switched-mode power supply charger device in step 122.

[0184] The device-related data obtained in step 122 may include device status data. The device status data may include information regarding the status of at least one component of the respective first and / or second device(s). The device status data may include or be derived from parameters measured by the device, such as battery health status, the status of components that experience wear during use of the respective first and / or second device(s) (such as the outer blade or cutting blade of a hair-cutting device), or other status information indicative of the status of the device or its components. Some or all of the data may be measured by the respective first and / or second device(s), optionally buffered in the respective first and / or second device(s), and read by the switched-mode power supply charger device in step 122. Some or all of the data may be obtained by the switched-mode power supply charger device (e.g., by deriving battery health information from charging current and / or voltage during a charging or battery calibration cycle).

[0185] Device-related data may be transmitted by the power supply device in step 123. The switched-mode power supply charger device may transmit device-related data for one or more devices (such as various personal care or other household devices) without requiring the user's cell phone or computer to be involved in the data collection and transmission.

[0186] FIG. 9 is a flowchart of a method 130 that may be performed by a power supply device.

[0187] In step 131, the switched mode power supply charger device may provide power to a first device.

[0188] In step 132, the switched-mode power supply charger device obtains equipment-related data for a plurality of devices. The plurality of devices may or may not include the first device. The plurality of devices may include one or more devices that may be engagable with an equipment connector of the power device. The plurality of devices may include one or more devices that are not engagable with an equipment connector of the power device. The plurality of devices may include one or more devices that include an electromechanical actuator. The plurality of devices may include one or more devices that do not include an electromechanical actuator but that include monitoring circuitry for monitoring use of the respective devices.

[0189] The device-related data obtained in step 132 may include device operational data or device status data, as described above.

[0190] In step 133, equipment-related data may be transmitted by the power supply device. The switched-mode power supply charger device may transmit equipment-related data for one or more equipment (such as various personal care or other household equipment) without requiring the user's cell phone or computer to be involved in the data collection and transmission.

[0191] Figure 11 is a flow chart of a method 140 of manufacturing a power device. The steps of the method are illustrated in Figures 12-14.

[0192] In step 141, the communication circuit 90 is assembled onto a power plug component 150 having connector pins 52, 53 for mating with a power outlet and a first compartment 61. The first compartment 61 houses a converter 71 having a converter input and a converter output galvanically isolated from the converter input. The first compartment is defined by a wall 65 that may be positioned opposite and spaced apart from an end wall 64 from which the connector pins 52, 54 protrude. A circuit board of the communication circuit 90 may be positioned on and attached to the wall 65 (FIGS. 12 and 13). The power plug component has a waterproof (e.g., IPX4 or higher) enclosure 63.

[0193] In step 142, an electrical connection may be established. The electrical connection may be established such that a conductive path is established from the converter output of converter 71 to the power input of communication circuitry 90, through communication circuitry 90, to the power output of communication circuitry 90. Step 142 may include connecting a conductor passing through a passage in wall 65 to the power input terminal of the communication circuitry (FIG. 13).

[0194] In step 143, end cap 69 may be attached to enclose communication circuitry 90 (FIGS. 13 and 14). Conductors extending through power cable 54 may be electrically connected to the power output of communication circuitry 90 (FIG. 14).

[0195] The end cap 69 may be engaged with the enclosure 63, for example, at the wall 65 or at a side wall of the enclosure 63 extending between the walls 64, 65. The connection between the end cap 69 and the enclosure 63 may be, but need not be, waterproof. The attachment of the end cap 69 may be performed such that the second compartment 62 defined between the end cap and the wall 65 may have an IPX rating (e.g., determined according to ISO 20653, DIN 40050-9, or IEC 60529) lower than the IPX rating of the compartment 61. The end cap 69 may be attached by ultrasonic welding 67, adhesive, or other attachment means. The fastening means may extend circumferentially around the entire periphery where the end cap 69 contacts the enclosure 63.

[0196] Various effects and advantages are achieved by the present invention. The power supply devices, kits, systems, and methods facilitate the transmission of data collected by devices, particularly personal care devices. The power supply devices, kits, systems, and methods allow device-related data to be transmitted over a desired wireless communication standard (such as a member of the IEEE 802.11 family of standards) without requiring (while still allowing) the device itself to have the communications circuitry required for that particular communications standard. The switch-mode power supply charger device can be manufactured in an efficient manner.

[0197] The dimensions and values ​​disclosed herein should not be understood as being strictly limited to the exact numerical values ​​recited. Instead, unless otherwise indicated, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as "40 mm" is intended to mean "about 40 mm."
