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.

In order to decrease the distance between individual antennae in the array, the antennae are submersed in a high dielectric material in addition to being arranged at right angles to one another, both features precluding one or more antennae from coupling. Furthermore, wires are covered in high dielectric material in order to refract RF signals around them, allowing antennae towards the center of the array to successfully transmit signals past other layers.

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.

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.
