摘要： A method of operating a transceiver system includes receiving, from a client power receiver, a signal at a plurality of antenna elements of an antenna array. The method also includes determining, by at least one of the antenna array and a processor of the transceiver system, and based at least in part on a fixed geometry of the plurality of antenna elements, a value of at least one waveform characteristic of the received signal. The method further includes computing, by the processor and based on the determined value of the at least one waveform characteristic, a transmission path of the signal from the client power receiver to each antenna element. The method also includes, assigning, by the processor and based on the computed transmission path, a location of the client power receiver in a wireless data transmission and power delivery environment.

摘要： Various embodiments of the present technology relate generally to wireless power systems. More specifically, some embodiments relate to the use of time reversal techniques utilizing time diversity (e.g., different multipath arrivals at the same antenna) to achieve coherency from the same transmission node. For example, instead of initiating outgoing transmissions (e.g., power signals) at the same time, various embodiments can initiate the outgoing signals from the various antennas in a staggered timing that is a reversal of the arrival times of an incoming signal. As a result of staggering the start of the outgoing signals, the signals will arrive at the destination at approximately the same time even though they have traveled different paths having different propagation delays.

摘要： Systems and methods are described for operating a wireless power transmission system. The wireless power transmission system receives an encoded beacon signal delivered from and initiated by a wireless power receiver client configured to receive wireless power from the wireless power transmission system. The wireless power transmission system also delivers wireless power to the wireless power receiver client and simultaneously detects for additional encoded beacon signals delivered from and initiated by additional wireless power receiver clients.

摘要： For determining operational status of components of a wireless signal transmission environment, a signal is received from a client power receiver (CPR), and at least one waveform characteristic value of the signal is calculated. Based on the determined waveform characteristic value(s), a current transceiver system operational status is computed for the CPR at a current location. The determined current transceiver system operational status is compared with a prior-stored last known good transceiver system operational status for the CPR at the current location, and it is determined if, as a result of the comparing, the current transceiver system operational status matches the prior-stored last known good transceiver system operational status for the CPR at the current location. Determining a presence or an absence of the match facilitates identifying one of a presence and an absence of: functional problem(s) in: at least one of the transceiver system and the CPR.
