Abstract:
A wireless powering device for providing directional wireless power to a target device. The wireless powering device includes a power source and communication circuitry configured to receive a communication signal from the target device. The wireless powering device further includes source power manager circuitry configured to determine (e.g., based on the communication signal) a location of the target device relative to the wireless powering device. Resonant coupling circuitry is coupled to the power source and the source power manager circuitry, the resonant coupling circuitry configured to generate a directional wireless power transmission, based on the location of the target device, to transfer wireless power to the target device. In an embodiment, the directional wireless power transmission is via non-radiated magnetic field. In another embodiment, the direction wireless power transmission is via a radiated magnetic field.
