    Abstract: An electronic lock that interacts with a mobile device is presented. In accordance with some embodiments, an electronic lock includes a wireless power receiver configured to receiver power from a mobile device; a processor coupled to receive power from the wireless power receiver; a memory coupled to the processor and to receive power from the wireless power receiver; a communication unit coupled to the processor and to receive power from the wireless power receiver, the communication unit configured to communicate with the mobile device; and an actuator coupled to the processor and to receive power from the wireless power receiver. The processor executes instructions stored in a memory for authenticating the mobile device, and providing signals to the actuator according to instructions received from the mobile device once it is authenticated. The mobile device provides power to the electronic lock and instructs it to lock or unlock a locking mechanism.

    Abstract: In accordance with aspects of the present invention, a first wireless power enabled device includes a transceiver and control logic. The transceiver includes a plurality of switches coupled in a full-bridge configuration with a resonant tank circuit. The control logic is configured to detect a presence of a second wireless power enabled device, establish a trusted relationship with the second wireless power enabled device, determine an operating mode of the first wireless power enabled device selected from a transmit mode or a receive mode, and drive the plurality of switches to operate the resonant tank circuit in the determined operating mode. The first wireless power enabled device may further include a memory that stores a copy of a first key associated with the first wireless power enabled device and a copy of a second key associated with the second wireless power enabled device.

    Abstract: A wireless power receiver may include a receive coil configured to generate an AC power signal responsive to wireless power transfer from a wireless power transmitter, and control logic configured to detect misalignment of the receive coil and a transmit coil of the wireless power transmitter responsive to a determination of efficiency of wireless power transfer therebetween. A method for operating a wireless power receiver may include detecting misalignment between a receive coil and a transmit coil of a wireless power transmitter responsive to detecting monitoring a value indicative of efficiency of wireless power transfer between the wireless power transmitter and the wireless power receiver, and causing an indication to be provided to a user to assist with correcting the misalignment.
