Abstract: A task performance system and method including multiple transmitters and multiple task devices distributed in a local area. Each task device includes communication circuitry, a memory, a controller, and output circuitry. The communication circuitry receives timing information and position information from the transmitters. The transmitters may also transmit task information including task location parameters that define the task area. The task area is divided into subblocks each having a corresponding task value. The controller uses the received information to determine its location and accesses the memory when located within the task area to retrieve a corresponding task value based on subblock location. The task information includes task values which may define a different task for each subblock. The controller activates output circuitry in accordance with the task value to perform a corresponding task. The output circuitry may include one or more light sources, a speaker, a vibration device, etc.

Abstract: Wireless power is provided to a WPP-compliant wireless device by generating a first radio frequency (RF) signal at a first frequency. The transmitter circuit is inductively coupled to the compliant wireless device using the first RF signal. A second RF signal is generated at a second frequency. The presence of a WPP-noncompliant wireless device is detected by detecting a third RF signal at a third frequency that is a harmonic of the second frequency. The non-compliant wireless device is protected by reducing, in response to detecting the third RF signal, a signal strength for the first RF signal.

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.
