One aspect of the present disclosure provides a wireless power transmission system including a power transmission device and a power receiving device. The power receiving device includes a first power receiving circuit including three receiving coils connected in a delta configuration. The three receiving coils are configured (i) to be magnetically coupled with two or more transmitting coils in the power transmission device and (ii) to output a first polyphase AC power in response to two or more single-phase alternating currents being supplied to the two or more transmitting coils, respectively.

A wireless charger comprises a top cover; a metallic case; and a first high-k heat-conducting material, disposed between a bottom surface of the top cover and a top surface of the metallic case to form a heat conductive path from the top cover to the metallic case via the first high-k heat-conducting material for dissipating heat generated by an electronic device disposed on the top cover for wireless charging the electronic device.

Disclosed are bed systems with a foundation having first and second side rails opposite each other and a pocket integrated into an exterior side of at least the first side rail at a distance from a head section of a mattress that is less than a distance from a foot section of the mattress. The pocket can include an inner pocket smaller than the pocket and positioned inside the first pocket. The pocket can include a charging port housing and a charging port supported by the charging port housing. The charging port can be a USB and/or USB-C port. The first side rail can also include a wireless charger and transmitter (e.g., induction charger) integrated therein for providing induction charging to a user device placed inside the pocket. The wireless charger and transmitter can be integrated into a structure of the first side rail at a location opposite the pocket.

A method of operating a wearable monitoring system in which a tablet or smartphone-sized device directly charges a wristband without separate cords or swappable batteries. The method includes prompting docking based on a low wristband battery or a scheduled charging window, maintaining the tablet's full usability while docked, and charging via inductive power transfer (without exposed contacts) or via conductive interfaces (pins or surface pads). Retention may be magnetic, mechanical, or combinations thereof. The method improves charging compliance, ingress protection, tamper resistance and safety.

One of the big challenges for anyone who owns a portable electronic device is the need to constantly maintain a charge on the device. Typically, the portable electronic device is sold with a power cord that the user can plug into an outlet of a home or a car. Many users have one power cord for the car and a separate cord for the car so that the user always has the capability to charge the portable electronic device. The current device will charge the portable electronic device using a photovoltaic panel that is attached to the back surface of the portable electronic device with a clip that is either integral to the solar panel or a removable clip in an alternative embodiment.

An electronic device includes: a power supply device, a first audio-visual device and a second audio-visual device. The first audio-visual device is detachably connected with the power supply device. The second audio-visual device is detachably connected with the power supply device. When the first audio-visual device is connected with the first power supply device, the power supply device charges the first audio-visual device.

A charge system for wireless temperature probe includes a probe body and a charging relay box detachably connected with the probe body, the probe body is provided with a first wireless charging component and a sealing structure. The charging relay box is internally provided with a power supply module, a control module and a second wireless charging component configured to establish a near field communication path with the first wireless charging component, and the control module is used to control the power supply module to adaptively supply power to the probe body through the near field communication path, the probe body comprises a handle, a sealing ring, a probe tube and an internal assembly, a head of the internal assembly is inserted in the probe tube, and a tail of the internal assembly is inserted in the handle.

The present disclosure relates to a charging device. The charging device may comprise a body and a cover coupled to the body. The cover may comprise first charging circuitry, and the cover may be movable between a first position in which the cover is on a top surface of the body and a second position in which the cover is angled relative to the top surface of the body. The charging device may further comprise a board coupled to the body and comprising second charging circuitry.

A battery charging apparatus for device charging in a vehicle includes a charging device compartment, a housing, a blower, a charger, and a duct. The charging device compartment is configured to retain at least one device. The housing includes a top member, a bottom member, and an accommodating space. The housing further includes an air-return port. The blower is in the housing and has an input port and an output port. The charger is in the housing and between the top member of the housing and the blower. The duct has an input port and an output port. The input port of the duct is coupled to the output port of the blower, and the output port of the duct is coupled to the air-return port of the housing. The duct forms a barrier between the accommodating space and the air-return port of the housing.
