A circuit includes power reception circuitry to convert an RF signal to a direct current signal for transmission to an energy storage device and/or an electronic device associated with the circuit. The circuit includes voltage regulator circuitry to regulate an output voltage of the circuit based on an internal state thereof. A method incudes receiving, by at least one antenna, the RF signal. The method includes converting, by the circuit coupled to the antenna, the RF signal to a direct current signal. The method includes transmitting the DC signal to the energy storage device and/or the electronic device. The method includes determining the internal state of the circuit. The method includes regulating the output voltage of the circuit based on the internal state. Embodiments enable the addition of wireless charging functionality to existing electronic devices without extensive internal and/or external redesign.

Wirelessly chargeable energy storage apparatuses having actively modifiable output voltages

A wirelessly powered electronic display apparatus and techniques for dynamically controlling the apparatus are described herein. More specifically, the electronic display apparatus is configured identify proximate users and automatically present communications to the proximate users in a wireless power delivery environment. In some embodiments, the apparatus comprises a housing, an electronic display disposed on the housing, one or more antennas situated within the housing and electronic circuitry situated within the housing. The electronic display is configured to present display data to proximate users in the wireless power delivery environment. The one or more antennas are configured to wirelessly receive power and data signals. The electronic circuitry is configured to harvest energy from the power signals, process the data signals to determine the display data for presentation to the proximate users, and direct the electronic display to present the display data to the proximate users.

Wirelessly powered electronic display apparatuses

In retrodirective wireless power delivery environments wireless power receivers generate and send beacon signals that are received by multiple antennas of a wireless power transmission system. The beacon signals provide the charger with timing information for wireless power transfers and also indicate directionality of the incoming signal. As discussed herein, the directionality information is employed when transmitting in order to focus energy (e.g., power wave delivery) on individual wireless power receiver clients. Techniques are described herein for reducing the burden of sampling the beacon signals across the multiple antennas and determining the directionality of the incoming wave. In some embodiments, the techniques leverage previously calculated values to simplify the receiver sampling.

Techniques for facilitating beacon sampling efficiencies in wireless power delivery environments

Embodiments of the present disclosure describe systems, methods, and apparatuses for reviving a wireless power receiver client over-the-air. More specifically, dual-mode active/passive wireless power receiver clients are described that can passively harvest RF energy in order to obtain enough energy to rejoin a wireless power network where the client can actively harvest RF energy (the client receives directed or isolated wireless power from a wireless power transmission system). For example, a wireless power receiver client can harvest RF energy while idle or off, e.g., when no beacon or other communications are being sent or received, or, in some instances, asynchronously in order to compliment and/or protect one or more elements of the system such as, for example a radio transceiver.

Dual-mode energy harvesting wireless power receiver apparatus with self-reviving capabilities

Embodiments of the present disclosure describe systems, methods, and apparatuses that actively regulate output voltage of wirelessly chargeable energy storage devices, e.g., wirelessly chargeable batteries. More specifically, techniques are described to emulate low-battery behavior of a standard battery, e.g., a typical AA battery, based on an internal state of the apparatus. The internal state can be determined based on commands provided by or to the apparatus or based on analog information such as, for example, an internal charge state, e.g., of a lithium-ion battery or capacitor.

Actively modifying output voltage of a wirelessly chargeable energy storage apparatus

Various techniques are described herein for calculating power consumption in wireless delivery systems. In one example, power consumption is calculated by receiving information associated with at least one portable device, identifying a discharge/charge curve associated with at least one battery in the at least one portable device, and calculating power consumption of the least one portable device based at least in part on the received information and the identified discharge/charge curve.

Calculating power consumption in wireless power delivery systems

Systems and methods are described for receiving wireless power and providing wired power. In some embodiments, a wirelessly chargeable battery apparatus comprises a housing and one or more antennas situated within the housing. The antennas are configured to receive wireless radio frequency (RF) power from a wireless charging system. One or more electronic circuit boards (PCBs) situated within the housing are included, and the one or more electronic circuit boards are configured to convert the received wireless RF power to direct current (DC) power. The apparatus also comprises one or more batteries configured to store the DC power and a port configured to couple with a cable external to the housing and to provide stored DC power from the one or more batteries to the cable.

Energy storage device for wireless environmental applications

Techniques are described for accumulating data regarding the charging environment and power delivery efficiency at various regions in the environment under various transmission conditions. In some embodiments, this data may be utilized to generate efficient and sophisticated power transmission schedules; however, this data may also be leveraged for the manipulation of the standing waves within the environment. This allows for two discrete and powerful applications: creation of null zones and conversely the generation of high power regions. These regions may also be referred to as 'power nulls' and 'energy balls' respectively.

Energy delivery modulation in wireless power delivery environments

Techniques are described for authenticating device in wireless power delivery environments. In some embodiments, a request for energy delivery is received from devices. The request may include an identifier, e.g., a client identification (ID). The charger may query a remotely located authentication platform via a network with the client ID. The authentication platform compares the client ID against devices that have been registered within the system. If the device is properly provisioned, the authentication platform may return an acceptance of authentication to the charger. In addition to device authentication, the current disclosure covers the ability to control the environment within a wireless network, and perform system diagnostics by monitoring the network environment.
