    摘要: The disclosed wireless transmitter estimates a client location in space and transmits power in the form of electromagnetic (EM) waves to that location. In response to receiving the power, a client sends a power request signal. In some implementations, the power request signal includes a request that the wireless transmitter transmit more power to the client. In response to the power request signal, the wireless transmitter can modify the power transmitted to the client to increase/decrease the amount of power the client is receiving. For example, the wireless transmitter can modify the emitted EM waves to increase coherent addition or decrease coherent addition at the location of the client to increase the amount of power the client receives. In some implementations, the wireless transmitter modifies the phase distribution of EM waves to increase the amount of power a client receives.

    摘要: Systems and methods for leveraging multipath wireless transmissions for charging devices within multipath signaling environment. Techniques according to the present technology include determining a received signal strength of a radio frequency signal received via a plurality of paths at two or more antennas of a plurality of antennas of an antenna array. The techniques also include configuring parameters for transmission of a wireless power signal over one or more paths of the plurality of paths for which the received signal strength exceeds a threshold value. The techniques further include directing at least a portion of the plurality of antennas to transmit the wireless power signal over the one or more paths according to the parameters. Resulting signal transmissions may thus be directionally biased toward least lossy pathways between a wireless power transmitter and a device in need of receiving wireless power.

    摘要: A system includes at least one antenna and a controller. The controller is configured to identify a phase of a first signal received by the at least one antenna from a wireless device. The controller is configured to determine transmission settings for the at least one antenna based on the identified phase. The controller is configured to generate, according to the transmission settings, a second signal for focusing on a wireless device. A method includes identifying a phase of a first signal received by a first transceiver from a second transceiver. The method includes determining transmission settings for the first transceiver based on the identified phase. The method includes generating, according to the transmission settings, a second signal for focusing on the second transceiver. Embodiments improve the power efficiency of wireless signal transmission.
