Abstract:
An example method is performed at a near-field charging pad that includes a wireless communication component, and a plurality of power-transfer zones that each respectively include at least one power-transferring element and a signature-signal receiving circuit. The method includes: sending, by a respective power-transferring element included in a first power-transfer zone of the plurality of power-transfer zones, test power transmission signals with first values for a set of transmission characteristics. The method also includes: in conjunction with sending each of the power transmission signals: detecting, using the signature-signal receiving circuit, respective amounts of reflected power at the first power-transfer zone. The method further includes: based on the respective amounts of reflected power, determining whether (i) an authorized wireless power receiver and/or (ii) an object other than a wireless power receiver is present on a surface of the charging pad that is adjacent the first power-transfer zone.

Claim (Index 1):
A method of operating a near-field charging pad, comprising:\n at a near-field charging pad that includes one or more processors and a plurality of power-transfer zones that each respectively includes at least one power-transferring element and a signature-signal receiving circuit: sending, by a respective power-transferring element included in a first power-transfer zone of the plurality of power-transfer zones, a plurality of test power transmission signals with first values for a first set of transmission characteristics; in conjunction with sending each of the plurality of test power transmission signals, detecting, using the signature-signal receiving circuit, respective amounts of reflected power at the first power-transfer zone, wherein the respective amounts of reflected power correspond to energy from the test power transmission signals of the plurality of test power transmission signals that was reflected outside of the near-field charging pad and returned to the first power-transfer zone; and based at least in part on the respective amounts of reflected power, determining whether (i) an authorized wireless power receiver and/or (ii) an object other than a wireless power receiver is present on a surface of the near-field charging pad that is adjacent to the first power-transfer zone.
