    Abstract: A communication system that uses keyed modulation to encode fixed frequency communications on a variable frequency power transmission signal in which a single communication bit is represented by a plurality of modulations. To provide a fixed communication rate, the number of modulations associated with each bit is dynamic varying as a function of the ratio of the communication frequency to the carrier signal frequency. In one embodiment, the present invention provides dynamic phase-shift-keyed modulation in which communications are generated by toggling a load at a rate that is a fraction of the power transfer frequency. In another embodiment, the present invention provides communication by toggling a load in the communication transmitter at a rate that is phase locked and at a harmonic of the power transfer frequency. In yet another embodiment, the present invention provides frequency-shift-keyed modulation, including, for example, modulation at one of two different frequencies.

    Abstract: A wireless power receiver capable of receiving wireless power from close-coupled and mid-range wireless power supplies. The wireless power receiver includes a principal and supplemental receiver circuits. The principle receiver circuit is adjustable to operate in a close-coupled mode or a resonator mode. In close-coupled mode, the principle receiver circuit is coupled to the power input of a remote device and functions as the principle power source. In resonator-mode, the principle power circuit is electrically disconnected/isolated from the remote device and forms a closed resonant loop to function as a resonator that amplifies an electromagnetic field from a mid-range wireless power supply. The supplemental receiver circuit is coupled to the power input of the remote device and is configured to receive wireless power from the resonator and function as the power source when the principle receiver circuit is in the resonator mode.
