Abstract: A wireless power system has a wireless power transmitting device that uses an inverter to apply alternating-current signals to a coil. In response, the coil generates wireless power signals that are received by a coil in a wireless power receiving circuit of a wireless power receiving device. While wireless power is being transferred to the receiving device, the receiving device communicates with the wireless power transmitting device using in-band communications. The wireless power receiving device can issue a halt-wireless-power-transmission command using in-band communications to direct the wireless power transmitting device to stop transmitting wireless power. When power is not being transferred, the wireless power transmitting device transmits a series of short impulses that are monitored by the receiving device. The receiving device can direct the transmitting device to resume power transmission by adjusting an adjustable impedance circuit coupled to the wireless power receiving circuit.

Abstract: A receiver device in an inductive energy transfer system can include a touch sensing device. If the input surface of the touch sensing device is touched, a transmitter device can periodically stop transferring energy to allow the touch sensing device to sense touch samples while inductive energy transfer is inactive. Additionally or alternatively, a transmitter device can produce an averaged duty cycle by transferring energy to the receiver device for one or more periods at a first duty cycle step and for one or more periods at different second first duty cycle step. Additionally or alternatively, a transmitter device can reduce a current level received by a DC-to-AC converter if the current received by the DC-to-AC converter equals or exceeds a threshold. Additionally or alternatively, a transmitter device can ping a receiver device and transfer energy only after a response signal is received from the receiver device.
