Abstract: Embodiments of an apparatus are disclosed. In an embodiment, a power receiver unit is disclosed. The power receiver unit includes a power pick-up unit, a communication modulator, and a filter. The power pick-up unit receives a wireless power signal. The communication modulator applies a modulation to the received wireless power signal. The filter suppresses a load signal from a load of the wireless charge receiver to prevent interference with the modulation.

Abstract: A method for authorizing a service is disclosed. In the embodiment, the method involves receiving a packet carried via a first power signal according to an inductive wireless power transfer communications protocol, the packet received at a power receiver within a mobile device, extracting a password from the received packet, storing the extracted password in memory within the mobile device, transmitting the stored password in a packet via a second power signal according to the inductive wireless transfer communications protocol to authorize a service.

Abstract: A method for performing foreign object detection in an inductive wireless power transfer system is disclosed. In the embodiment, the method involves obtaining measurements from a base station of a wireless power transfer system during charging and determining transmitter energy loss in a power transmitter, Ptxloss, using the obtained measurements, wherein the transmitter energy loss, Ptxloss, is a function of at least Vcap and PTx, wherein Vcap is proportional to the voltage amplitude across the capacitor of an LC tank circuit in a power transmitter and PTx is the total power supplied to the power transmitter. The method also involves detecting the presence of a foreign object in response to the estimated transmitter energy loss.
