Abstract: At least one component for a wireless power transmitter or a wireless power receiver. The at least one component includes a mechanical structure and/or circuitry configured to maintain and/or adjust a coupling coefficient K between the wireless power transmitter and the wireless power receiver, a loaded quality factor Q of the wireless power receiver, or both, such that K times Q is less than a constant.

Abstract: Techniques and examples pertaining to combined wireless charging and position tracking are described. A method may involve a processor of an apparatus operating in a first mode to effect wireless charging via at least a first coil of a plurality of coils of the apparatus. The method may also involve the processor operating in a second mode to effect position tracking via at least a second coil of the plurality of coils of the apparatus.

Abstract: An apparatus and method for performing foreign object detection for a wireless power transmitter. A matching network and transmit coil are energized, and a resonance is excited. The resonance is allowed to decay. A temporal characteristic of the decay is measured. The temporal characteristic is analyzed to determine whether a foreign object is coupled to an electromagnetic field generated by the transmit coil.
