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.

Abstract: Apparatus and methods for configuring power settings of a wireless power transmitter installed adjacent to a partition are described. A wireless power receiver may detect an amount of power transmitted through the partition from the power transmitter, and identify at least one power setting to the power transmitter that produces an acceptable level of wirelessly transferred power at the wireless power receiver. The power transmitter may store an identified power setting and subsequently operate at the setting identified by the wireless power receiver to provide wireless power through the partition for powering or charging a wirelessly powered device. By configuring a wireless power transmitter at an installation site, various partition thicknesses may be accommodated for through-table, wireless power transfer, for example.
