Abstract: A passive sensor unit that is powered wirelessly and communicates with a reader unit that powers the pass sensor unit is presented. In some embodiments, a passive sensor unit includes a sensor; a receive coil; a circuit coupled to the sensor, the circuit configured to receive sensor data from the sensor; and a wireless power circuit configured to receive power from the receive coil and configured to provide power to the circuit. The pass sensor unit is unpowered except proximate to the reader unit. A sensor system can include one or more passive sensor units, each of the one or more passive sensors configured to receive wireless power from a receiver coil and communicate data through the receiver coil; and one or more reader units, each of the one or more receiver units configured to supply power and communicate with a set of the one or more passive sensor units.

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
