First Claim
1. A method for configuring a wireless power transmitter to transmit power wirelessly through a partition between a wireless power receiver and the wireless power transmitter at an installation location of the wireless power transmitter, the method comprising:
- detecting, at the wireless power receiver, a plurality of signals representative of wirelessly received power levels by at least one receiving coil of the wireless power receiver, wherein the power levels correspond to wireless power transmitted in a sequence of power levels by the wireless power transmitter through the partition;
indicating, on a display of the wireless power receiver, a direction in which to move the wireless power receiver to receive a higher magnetic field from the wireless power transmitter; and
identifying by the wireless power receiver, to the wireless power transmitter, at least one transmit power level of the power levels received from the wireless power transmitter that provides a received power level at the at least one receiving coil that is suitable for charging and/or operating a wireless power device, wherein the identifying occurs after the plurality of signals have been detected by the wireless power receiver.

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.
