REVERSE LINK SIGNALING VIA RECEIVE ANTENNA IMPEDANCE MODULATION
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（中）：

示例性实施例涉及无线功率传输，包括在发射天线的谐振频率处产生电磁场，以在发射天线的近场内产生耦合模式区域。 放置在耦合模式区域内的接收天线在谐振频率处或谐振频率处共振。 接收天线从两个天线之间的耦合中提取能量。 从接收天线到发射天线的信令通过产生用于接收天线的第一功率消耗状态来发信号通知第一接收信号状态并产生用于接收天线的第二功率消耗状态来发出第二接收信号状态。 通过使得发射天线上的谐振频率能够发信号通知第一发射信号状态并禁用发射天线上的谐振频率来发出第二发射信号状态来执行从发射天线到接收天线的信令。
