Abstract: Exemplary embodiments are directed to wireless power. A wireless power receiver includes a receive antenna for coupling with near field radiation in a coupling-mode region generated by a transmit antenna operating at a resonant frequency. The receive antenna generates an RF signal when coupled to the near filed radiation and a rectifier converts the RF signal to a DC input signal. A direct current (DC)-to-DC converter coupled to the DC input signal generates a DC output signal. A pulse modulator generate a pulse-width modulation signal to the DC-to-DC converter to adjust a DC impedance of the wireless power receiver by modifying a duty cycle of the pulse-width modulation signal responsive to at least one of a voltage of the DC input signal, a current of the DC input signal, a voltage of the DC output signal, and a current of the DC output signal.

Abstract: Exemplary embodiments include an antenna for receiving electromagnetic radiation in a broadcast radiation band and a near-field radiation band to generate a Radio Frequency (RF) signal. A coupling element couples the RF signal to a first port and at least one additional port, which may be a second port and a third port. A wireless power receiver on the first port includes a rectifier for converting the RF signal to a DC signal when the antenna couples to radiation in the near-field radiation band in a coupling-mode region of the antenna. A near-field communication transceiver includes circuitry for communicating information on the antenna in the near-field radiation band when the coupling element couples the second port to the RF signal. A broadcast receiver on the third port includes circuitry for receiving and tuning the broadcast radiation band when the coupling element couples the third port to the RF signal.

Abstract: Exemplary embodiments are directed to wireless power transfer. A transmitting device or a receiving device for use in a wireless transfer system may be equipment or a household appliance. The transmitting device includes a transmit antenna to wirelessly transfer power to a receive antenna by generating a near field radiation within a coupling-mode region. An amplifier applies an RF signal to the transmit antenna. A presence detector detects a presence of a receiver device within the coupling-mode region. A controller adjusts a power output of the amplifier responsive to the presence of a receiver device. The presence detector may also detect a human presence. The power output may be adjusted at or below the regulatory level when the presence signal indicates human presence and above a regulatory level when the presence signal indicates human absence.
