Abstract
A transmitter includes a first resonator to generate an oscillating field at a resonant frequency in response to receiving power from a power source. The transmitter includes a first communication interface and a first controller to control the first resonator and to communicate data via the first communication interface. One of a plurality of receivers includes a second resonator to be wirelessly coupled to the first resonator. The second resonator resonates at the common mode resonant frequency in response to the oscillating field. The one receiver includes a second communication interface to establish wireless side-channel communications with the first communication interface and to communicate the data with the first communication interface via the wireless side-channel communications. The first controller identifies the one receiver from the plurality of receivers according to the communicated data, and in response, the first resonator transfers the power to the second resonator.
