Systems and methods are described for operating a wireless power transmission system. The wireless power transmission system receives a 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.

Systems and methods for providing over-the-air power to charging pads. A system may include means for transducing over-the-air energy into electric power, at least one rechargeable battery coupled to the means for transducing, and at least one charging pad coupled to the at least one battery. The system may be positioned at least in part in at least one cavity positioned underneath a user-accessible surface of an apparatus. A method may include the steps of transducing over-the-air energy into electric power, inducing a first direct current from the electric power, transmitting the first direct current to at least one rechargeable battery, and transmitting a second direct current from the at least one rechargeable battery to at least one charging pad. Improvement of spaces used by people in need of charging various electronic devices may be achieved without such facility spaces having to undergo costly structural modifications.

Described herein are embodiments of apparatuses and methods for optimizing transmissions of wireless power to a wireless power receiver (WPR). In some embodiments, a plurality of subantennas transmit a respective plurality of beacon signals in a beacon duration. Each of the respective plurality of beacon signals is associated with a respective phase set. At least one of the plurality of antennas receives, following the beacon duration, a wireless power transmission transmitted by a wireless power transmitter (WPT). The wireless power transmission uses phase settings based on at least one phase set derived from at least one beacon transmitted in the beacon duration. Direct current (DC) voltage is provided from radio frequency (RF) energy received in the wireless power transmission.

Systems, methods, and apparatuses for receiving wireless power using a wireless power receiver client architecture are disclosed. A simplified wireless power receiver apparatus includes an energy storage device and a radio frequency (RF) transceiver including an antenna. Energy harvester circuitry is coupled to the energy storage device and the RF transceiver, and control circuitry is coupled to the energy storage device, the RF transceiver, and the energy harvester. The control circuitry causes the RF transceiver to: establish a connection with a wireless power transmitter (WPT), transmit a beacon signal to the WPT, and receive a wireless power signal from the WPT. The control circuitry causes the energy harvester to deliver at least a portion of energy of the wireless power signal to the energy storage device for storage therein. In some embodiments, a single antenna is utilized both for transmitting the beacon signal and for receiving the wireless power signal.

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.

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.

The wireless power transmission is a system for providing wireless charging and/or primary power to electronic/electrical devices via microwave energy. The microwave energy is focused to a location by a power transmitter having one or more adaptively-phased microwave array emitters. Rectennas within the device to be charged receive and rectify the microwave energy and use it for battery charging and/or for primary power.

Systems, methods and computer-readable media according to the present technology enable a receiver to detect and characterize background signals and/or interfering noise to establish a blocker/interferer signal signature, or background signature, for a multi-signal wireless signaling environment. The processes and methods according to present technology can be implemented as a continuous process. Alternatively, where a transmitter and associated receiver operate for wireless signaling according to an expected or predetermined schedule, the processes described herein need not run at all times, but rather can be scheduled for only such times and durations sufficient to achieve the advantageous technical effects. In either case, the present technology provides a power-, memory-, and computation-efficient technique for both the transmitter and the receiver devices.

Various wireless power transmission systems are provided for sensing an environment, e.g., using a neural network. For instance, phase information corresponding to wireless power transmission is input into a neural network framework, and then, distance information representative of a distance from a wireless power transmitter to an object is obtained as output from the neural network framework. Based on the distance information, a power of a subsequent wireless power transmission can be modified, or an environment comprising the object can be mapped.

A fixture for providing over-the-air power to portable electronic devices may include a surface, a charging pad configured to charge a portable electronic device resting on the surface via wireless power transfer, a technology layer underneath the surface, and at least one energy storage device positioned at least in part in the technology layer and configured to provide a voltage. The fixture may include a receiver positioned at least in part in the technology layer and configured to: receive the over-the-air energy from at least one source thereof, and transduce the over-the-air energy to an electric current to charge the at least one energy storage device. The fixture may include at least one power converter positioned at least in part in the technology layer and operably coupled to: the at least one energy storage device, and the charging pad.
