    摘要： Exemplary embodiments are directed to wireless power transfer including generating an electromagnetic field at a resonant frequency of a transmit antenna to create a coupling-mode region within a near-field of the transmit antenna. A receive antenna placed within the coupling-mode region resonates at or near the resonant frequency. The receive antenna extracts energy from a coupling between the two antennas. Signaling from the receive antenna to the transmit antenna is performed by generating a first power consumption state for the receive antenna to signal a first receive signal state and generating a second power consumption state for the receive antenna to signal a second receive signal state. Signaling from the transmit antenna to the receive antenna is performed by enabling the resonant frequency on the transmit antenna to signal a first transmit signal state and disabling the resonant frequency on the transmit antenna to signal a second transmit signal state.

    摘要： Exemplary embodiments are directed to communicating information relating to wireless charging. A power transmitting system includes a host device with a transmit antenna. A communication interface conveys receiver information, which includes unique identifier information, from a receiver device to the host device. A controller on the host device monitors and processes the receiver information to generate notification information, which is presented to a user on a user-perceivable notifier. The transmit antenna generates an electromagnetic field at a resonant frequency to create a coupling-mode region within a near-field of the transmit antenna. The system can detect a presence of a receiver device with a receive antenna that is in the coupling-mode region and process a request for power from the receiver device. The system can also notify a user when a host device is leaving a designated region and whether the host device includes expected receiver devices.
