Abstract: 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.

Abstract: Techniques are described herein for leveraging these existing components of electronic devices with wireless or internet connectivity to reduce cost, size and complexity of electronic devices while enabling wireless power transfer. The techniques described herein can also be utilized to new low cost dual-function devices that utilize one or more of the same components for both wireless connectively and wireless power transfer.

Abstract: Techniques for static tuning retro-directive wireless power transmission systems are described herein. The techniques described herein include systems, methods and software for establishing a static tuning mode for a retro-directive wireless power transmission system.

Additionally, techniques are provided for characterizing the wireless power delivery paths.

Abstract: Techniques are described for retention of known data within a wireless power transmission system, or within a cloud-based processing system. In order to perform scheduling procedures for determining which device to power, it is necessary to collect data regarding a device, e.g., the battery type, power usage, device model, present charge level and amount of power delivered per power cycle. A wireless power receiver client typically needs to collect or infer the information from the device and then provide the information directly to the charger via a messaging protocol. In existing wireless power transmission systems, information is re-transmitted to the wireless power transmission system every time the receiver engages or reengages the system.

Abstract: 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.

Abstract: Systems and methods are described for providing wireless power. In some embodiments, a method for wireless power transmission comprises sending, via an antenna of a first wireless power receiver client and during a first tone time block, a beacon signal to a wireless power transmission system. During a first power tick time block of a plurality of power tick time blocks, a wireless power signal is received from an antenna array of the wireless power transmission system. When not sending the beacon signal and when not receiving the wireless power signal, a low power mode is entered that is configured to consume less power than a power consumed by the first wireless power receiver during either the sending of the beacon signal or the receiving of the wireless power signal.

Abstract: 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.
