Patent ID: 11916408
Assignee: GURU WIRELESS, INC.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A wireless power delivery system comprising:
a wireless power generation unit (GU) including:
a GU antenna array; and
a GU wireless communication circuit; and

one or more recovery units (RUs), wherein each RU comprises:
an RU antenna array; and
an RU wireless communication circuit,

wherein the GU antenna array is configured to use volumetric refocusing to scan the area for the one or more RUs by sweeping a wireless scan signal to be captured by the RU antenna array,
wherein volumetric refocusing comprises dynamically moving the focal point of the GU antenna array by applying different phase settings to the wireless scan signal and utilizing a phase table obtained by focusing into a known location and re-calculating the phase settings to refocus the wireless scan signal to a different point in space,
wherein when the RU antenna array receives the wireless scan signal, the RU wireless communication unit is configured to transmit a wireless signal back to the GU wireless communication unit,
wherein the GU is configured to record the focal coordinates of each RU based upon the signal received by the GU from each RU, and
wherein the GU is configured to emit a wireless power signal to the recorded focal coordinates of each RU to be received by each RU antenna array.
