摘要： The technology described herein relates to wireless power receivers with reconfigurable (or adaptive) antenna configurations for improved wireless power transfer in multipath wireless power delivery environments. In an implementation, a wireless power receiver is described. The wireless power receiver includes one or more radio frequency (RF) antennas, power metering circuitry and control circuitry. The power metering circuitry is adapted to measure at least one characteristic of wireless power received from a wireless power transmission system in a multipath environment. The control circuitry is adapted to monitor the power metering circuitry to determine when the measure of the at least one characteristic of the wireless power fails to meet a preset threshold, and dynamically reconfigure an antenna configuration of the wireless power receiver when the at least one characteristic of the wireless power fails to meet the preset threshold.

摘要： Techniques are described herein for delivering retrodirective wireless radio frequency (RF) power to a client device in a wireless power delivery environment. More specifically, embodiments of the present disclosure describe techniques for delivering directed wireless RF power to a client device in a wireless power delivery environment via multiple wireless power signals over multiple wireless power delivery paths. The client device includes one or more RF client transceivers that collectively have a radiation and reception pattern in a three-dimensional space proximate to the client device. The techniques identify the wireless power delivery paths over which wireless power signals can be delivered and deliver the wireless power in a manner that matches the client radiation and reception pattern in the three-dimensional space proximate to the client device.

摘要： Various embodiments of the present technology generally relate to wireless power transmitter and antenna configurations for transmitting wireless power to one or more clients. In some embodiments, the wireless power transmitter includes boards having multiple antennas (i.e., an Antenna Matrix Board(s) (AMB)). The antennas can be on one side of each AMB board, while the control and power circuitry are on the reverse side. The antennas emit electromagnetic (EM) radiant energy that the client(s) receive, store, and/or use for communication with the charger or for the client device battery charging process. The antenna boards can be arranged in a configuration to increase (e.g., optimize) the amount of power transmitted to client(s). In various embodiments, the boards are arranged in polygonal shape as individual flat panels physically coupled to a support structure and attached to the CCB by plug in multiple pin connectors unique in mechanical design.

摘要： The technology described herein relates to polarization adaptive wireless power transmission systems. In an implementation, a wireless power transmission system is described. The wireless power transmission system includes an antenna array and control circuitry operatively coupled to the antenna array. The control circuitry is configured to determine polarization information of a beacon signal received from a client device at multiple antennas of the antenna array. The beacon signal is transmitted by a client device in a wireless power delivery environment. The control circuitry is further configured to configure polarization information associated with each of the multiple antennas to match the polarization information determined at respective antennas of the multiple antennas. The present technology enables different wireless power receiver clients to have different polarizations. The wireless power transmission system can efficiently send power to the client devices by matching their polarization.

摘要： Circuits, systems and computer readable media transmission of wireless signals in response to incoming signals in a wireless signaling environment. Such a system may include at least one transceiver for receiving an incoming signal via an antenna array from a device in the wireless signaling environment. The system may also include a controller operably coupled to the transceiver. The controller may measure a phase of the incoming signal, and determine, based on the phase, a transmit phase configuration for one or more antennas of the antenna array. The system may include at least one phase-locked loop (PLL) operably coupled to the transceiver(s). The PLL(s) may feed signals to the antenna(s) of the antenna array based on the transmit phase configuration for transmission of a responsive signal to the device.

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.
