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

An enclosure for a wirelessly chargeable battery includes a housing having a base and an opposing open end, where a hole is bored through the base. The enclosure includes an end piece attached to the housing proximal the base and having an opposing open end. The enclosure includes a first conductive coating formed on an interior surface of the housing and a first surface of the base, and a second conductive coating formed on an interior surface of the end piece and a second surface of the base, where the housing and the end piece are configured in dimensions that conform to standardized battery dimensions. Battery cell(s) may be positioned inside a cavity in the housing, and circuitry may be positioned inside a cavity of the end piece. The enclosure enables highly efficient use of interior space and volume of the enclosure to maximize battery charge capacity.

Devices and systems for providing wirelessly chargeable batteries with improved charge capacities

Systems, methods and computer-readable media according to the present technology enable wireless power transmitters (WPTs) 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 power delivery environment. The processes and methods according to present technology can be implemented as a continuous process. Alternatively, where a WPT and associated receiver device operate for signaling and wireless power transmission 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 WPT and the wireless power receiver devices (e.g., WPRs).

Wireless power transmission system operations in multi-signal environments

The technology is generally directed towards wireless power charging of one or more receiver devices within a container that is electromagnetically shielded with respect to the frequency or frequencies used for the wireless charging. A controller determines, via signaling from one or more sensors, that the container is in the electromagnetically shielded state with respect to emitting external radiation at the charging frequency or frequencies. When electromagnetically shielded, the controller controls the output power state of a wireless power transmitter device to charge the one or more receiver devices. The controller can determine when to stop the charging of a receiver device, such as when sufficiently charged. The controller and wireless power transmitter device can charge the one or more receiver devices selectively, e.g., based on which one needs more charge or other criterion. The controller can obtain and externally communicate the state of charge of the receiver device(s).

Controlled wireless charging in an electromagnetically shielded environment

Systems and methods are disclosed for wireless power delivery that can provide wireless power, via a retrodirective wireless power transfer (WPT) channel, to a wireless power recipient in response to a modulated backscatter signal from a wireless power receiver. A wireless power receiver can produce a modulated backscatter signal and transmit such to a power delivery system to initiate a wireless power transfer linkage. In some examples, a dual-band technique can be implemented where a first band can be used as a dedicated retrodirective WPT channel while a data communication node can utilize a second band for a low energy compatible data communication type. Both a beacon signal (the backscattered signal) for retrodirective linkage at the first band and the communication signals at the second band can be produced via backscattering at the wireless power receiver. A backscattered beacon signal and a communication signal may be modulated and frequency multiplexed.

Embodiments of a conformal wave selector and methods of application thereof are disclosed. A conformal wave selector comprises a first plurality of conductors arranged substantially in parallel in a first direction and in a first region and a second plurality of conductors arranged substantially in parallel in second direction that is normal to the first direction and in a second region that is different than the first region. The conductors are sized, spaced, and directionally arranged such that signals of particular wavelengths and unknown polarization are reflected and other signals are allowed to penetrate the conformal wave selector.

Embodiments of an aperture expansion flap are disclosed. An aperture expansion flap may be used in conjunction with an antenna to expand an effective aperture of the antenna beyond its physical area, geometry, and orientation. An aperture expansion flap may include one or more resonators which may be tuned to adjust a reflection and/or refraction phase of an incident wireless signal, such that the wireless signal may be reflected and/or refracted at angle of reflection and/or refraction that is different than an angle of incidence.
