Abstract: In an embodiment, an apparatus is disclosed. The apparatus includes a battery and a wireless power receiver. The wireless power receiver includes a controller and a memory subsystem. The controller is configured to perform a handshake with a wireless power transmitter. The handshake corresponds to a temporary suspension of a power transfer between the wireless power transmitter and the wireless power receiver. The controller is configured to transition the wireless power receiver from a power transfer mode, in which power is transferred wirelessly from the wireless transmitter to the wireless receiver, to a cloak mode, in which the power transfer is suspended, based on the handshake and obtain a supply of power from the battery based on the transition to the cloak mode, the power being configured for use by the controller to maintain power transfer state information about the temporarily suspended power transfer in the memory subsystem.

Abstract: Systems and methods for demodulating a signal is described. A device can receive a modulated signal that encodes data. The device can sample a voltage of the modulated signal to generate a plurality of samples in digital domain. The device can determine in-phase data and quadrature data of the plurality of samples. The device can determine amplitude data and phase data based on the in-phase data and the quadrature data. The device can decode the amplitude data and phase data into digital symbols that represent the data encoded in the modulated signal.

Abstract: A method and a system may inductively determine a position of a display screen of a computing device. Associated processes may generate a magnetic field by providing an alternating current to a driver coil, and may generate a voltage at a sensor coil in response to the magnetic field. The system and method may additionally include determining a position of the display screen by executing an algorithm at a processor. An input to the algorithm may include voltage data associated with the voltage generated at the sensor coil.
