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： 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.

摘要： Timing Acquisition Module (TAM) configured for use in or associated with a WTPS and associated methods, apparatus, and systems. The TAM is configured to receive encoded beacons broadcast by wireless power receiver clients requesting power on demand. The TAM decodes the encoded beacons to identify which client broadcast the beacon and notifies the WPTS that a client is requesting power, along with an identifier of that client. In response, the WPTS transmits wireless power signals to the client to service the power request. The WPTS and client may use separate beacons or signals to command the client to broadcast its WPTS beacon, whereby phases of the beacon signal are detected by antennas in the WPTS antenna array and processed to direct the wireless power signals from the WPTS to the client. Multiple apparatus including a combination of a WPTS and TAM may be implemented in a wireless power environment in a cooperative manner, enabling a client to move within the environment while supporting power on demand.

摘要： Systems and methods are described for receiving wireless power and providing wired power. In some embodiments, a predictive phase estimation apparatus comprises a transceiver module configured to receive a plurality of beaconing signals from a wireless client during a beacon cycle. The predictive phase estimation apparatus also comprises a phase compensation module configured to store the received plurality of beaconing signals, a phase predictor module is coupled to the transceiver module and configured to calculate predictive phases based on the received plurality of beaconing signals and based on beaconing signals received from the wireless client prior to the beacon cycle, and a signal converter coupled to the transceiver module. The signal converter is configured to form transmission signals based on the predictive phases and supply the transmission signals to the transceiver module. The transceiver module also transmits the transmission signals for delivery of wireless power to the wireless client.

摘要： Various embodiments of the present technology relate generally to wireless power systems. More specifically, some embodiments relate to identifying and correcting failures within wireless power systems (or any other system that is subject to design/device fault). Some embodiments monitor multiple states/control signals in a wireless power transmission system having an array of antenna. A determination can be made as to whether each of the multiple states are in an expected configuration (or make the expected transitions implying different states during normal operations). For examples, this can include identifying whether each antenna in the array of antennas is in a transmitting or receiving state. Any problems (e.g., timing problems, antennas stuck in a Tx or Rx state, controller malfunction, etc.) within the system can be detected by analyzing the multiple states/control signals and compare them against expected behavior/configuration. Some embodiments can activate a mitigation protocol and/or recovery through re-try/re-initialization/re-boot processes.
