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.

Simplified wireless power receiver architecture

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.

Transmission path identification based on propagation channel diversity

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.

Circuits and systems for wireless signaling

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.

Wireless power transmission system

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.

Systems and methods for wireless signaling operations in multi-signal environments

Apparatus, system and method for operating a transmission line. The transmission line includes two non-electrically coupled conductive sections. At least one electronic device is coupled to and between the two sections of the transmission line. The at least one electronic device are configured to stably maintain, in the absence of electric current applied to the at least one electronic device, a conductive state, and a non-conductive state, as between the two sections of the transmission line.

Non-volatile, low power phase shifter for tapped transmission lines

A system for extracting oxygen from a liquid includes a separator allowing a liquid to pass lengthwise through the separator to produce a liquid mixture with the liquid having at least a portion of oxygen removed from the liquid. The separator includes a wall surrounding an interior portion of a tube. The wall has at least one aperture formed in the wall. The separator also includes at least one magnet positioned adjacently to the at least one aperture. The magnet has a north pole end and a south pole end. A magnetic field gradient is formed between the north pole end and the south pole end, and extends into an interior portion of the tube. The system also includes a storage tank fluidly coupled to the at least one aperture for storing the at least a portion of the oxygen removed from the liquid via the separator.

Systems for extracting oxygen from a fluid

Magnetic systems and methods for oxygen separation and purification from fluids utilizing the paramagnetic properties of oxygen. A magnetic field gradient is established in a tube having a first end in flow communication with a source of a fluid containing oxygen. The fluid is flowed through the tube. The magnetic field gradient causes oxygen to be enriched in the fluid on a first interior side of the tube as compared to a second interior side of the tube. For a fluid like air having oxygen, a paramagnetic substance, and other, e.g., diamagnetic, components like nitrogen, argon, carbon dioxide and water vapor, the technology of the disclosure effectively separates oxygen molecules from the other components in magnetic field gradients of sufficient magnitude.

Magnetic systems and methods for oxygen separation and purification from fluids

Described herein are embodiments of apparatuses and methods for optimizing pairing of a wireless power transmission system (WPTS) with a wireless power receiver client (WPRC) in a localized system. A current WPTS-WPRC pairing and at least one alternate WPTS-WPRC pairing are assessed and the WPTS-WPRC pairing is updated based on associated pairing quality metrics. In this way, a system of many WPTSs and WPRCs will approach an Epsilon equilibrium such that no WPRC would be significantly better served by being paired with a different WPTS.
