摘要： A wireless receiver system includes a receiver antenna, a sensor, a demodulation circuit, and a receiver controller. The sensor is configured to detect electrical information associated with AC wireless signals, the electrical information including, at least, a voltage of the AC wireless signals. The demodulation circuit is configured to receive the electrical information from the at least one sensor, detect a change in the electrical information, determine if the change in the electrical information meets or exceeds one of a rise threshold or a fall threshold, if the change exceeds one of the rise threshold or the fall threshold, generate an alert, and output a plurality of data alerts. The receiver controller is configured to receive the plurality of data alerts from the demodulation circuit, and decode the plurality of data alerts into the wireless data signals.

摘要： Wireless power transfer systems, disclosed, include a wireless power transmission system and a wireless power receiver system. The wireless power transmission system includes a transmitter antenna configured to couple with a receiver antenna to transmit alternating current (AC) wireless signals to the receiver antenna. Antenna coupling may be inductive and may operate in conformance to a wireless power and data transfer protocol. A transmission controller drives the transmitter antenna at an operating frequency, and either the wireless power transmission system or the wireless power receiver system may damp the wireless power transmission to create a data signal containing a serial asynchronous data signal.

摘要： A reconfigurable wireless power transfer system includes a first wireless transmission system, one or more secondary wireless transmission systems, and at least one wireless receiver system. The first wireless transmission system is configured to receive input power from an input power source, generate wireless power signals, and couple with one or more other antennas. Each secondary wireless transmission systems is configured to couple with one or more of another secondary transmission antenna, the first transmission antenna, and/or one or more receiver antennas. The secondary wireless transmission systems receive the AC wireless signals from the first wireless transmission system and repeat the AC wireless signals to one or more secondary transmission antennas, receiver antennas, or combinations thereof. The one or more receiver antennas are configured to receive the AC wireless signals to provide electrical power to a load operatively associated with a computer peripheral.

摘要： Wireless power transfer systems, disclosed, include one or more circuits to facilitate high power transfer at high frequencies. Such wireless power transfer systems include a transmission integrated circuit which includes a damping circuit and a transmitter controller, configured to dampen a wireless power signal such that communications fidelity is upheld at high power. The damping circuit includes at least a damping transistor that is configured to receive, from the transmitter controller, a damping signal for switching the transistor to control damping during transmission of the wireless data signals. Utilizing such systems enables wireless power transfer at high frequency, such as 13.56 MHz, at voltages over 1 Watt, while maintaining fidelity of in-band communications associated with the higher power wireless power signal.
