Abstract: Exemplary embodiments are directed to controlling impedance. A wireless power transmitter for controlling impedance comprises a transmit circuit configured to wirelessly transmit power to a plurality of receivers, each having a load resistance, within a charging region of the transmit circuit. The transmitter also comprises a controller configured to request each receiver of the plurality of receivers to adjust its load resistance to a value that achieves a target total impedance as presented to the controller.

Abstract: Exemplary embodiments are directed to a device include a parasitic coil for protection of the device. A device may include a first circuit configured to receive a first transmitted signal at an operational frequency. The device may also include a second circuit a second circuit configured to generate a field that opposes at least one of an undesirable portion of a wireless power field of the first transmitted signal and a portion of another wireless power field proximate the first circuit, the another wireless power field generated by a second transmitted signal at a non-operational frequency of the first circuit.
