Abstract: An inductive power transmitter comprising a transmission circuit having a coil, the transmission circuit tuned, adapted or optimised at or about a first frequency for inductive power transfer or object detection; an inverter operable to drive the transmission circuit at the first frequency; and a controller arranged to control the inverter to drive the transmission circuit at a second higher frequency, and to modulate a signal at the second higher frequency according to a predetermined handshake signal in order to generate a response from a predetermined non-authorised device proximate the coil.

Abstract: A wireless power transmission system comprising a wireless power transmitting device and a wireless power receiving device. The wireless power receiving device is configured to enter a cloak state when a temporary pause in power transfer is desired. The wireless power receiving device may allow or deny a communication data stream with the wireless power transmitting device during the cloak state. The wireless power receiving device may request a hot start power transfer phase with the wireless power transmitting device after the cloak state. The wireless power transmitting device may or revert (reset) to a default operating state in the event that a control error packet is received during the cloak state.

Abstract: A wireless power transmission system comprising a wireless power transmitting device and a wireless power receiving device. The wireless power receiving device is configured to regulate power drawn during a power transfer phase to maintain a substantially steady power level that is less than or equal to a power consumption level demanded by an associated load. The wireless power transmitting device is configured to determine the presence of a foreign object by monitoring the power transmitted or the power received and identifying a characteristic change in steady state power indicative of the presence of a foreign object.

Abstract: A system for wireless power transfer control comprising a receiver for receiving and consuming power, a transmitter for transmitting power, wherein the receiver is configured to generate and send a message to the transmitter, the transmitter is configured to control an output level transmitted to the receiver based on the message, and wherein the receiver or the transmitter is configured to perform a corrective action if a magnitude of the message exceeds a power error threshold for a threshold time.
