Intelligent multi-mode wireless power system
First Claim
1. A method of providing wireless power to a device load, comprising:
- transmitting a directed energy signal over-the-air from an energy transferring unit (ETU) to an energy receiving unit (ERU) of the device load in a first mode when the ERU is in a far field range of the ETU; and
,generating a resonant magnetic field over-the-air by said ETU wherein said resonant magnetic field is coupled with an ERU magnetic field at the same resonant frequency of the ERU of the device load in a second mode when the ERU is in a near field range of the ETU, the far field range being greater than the near field range,wherein energy is transferred to the ERU from the ETU by selectively managing the directed energy signal and the resonant magnetic field to deliver energy as needed by one or both of the modes simultaneously and with consideration to the device load'"'"'s energy requirement, energy priority and device load'"'"'s range relative to the ETU.

Abstract
The present disclosure provides a method and system for intelligently managed multi-mode wireless transfer of energy for charging and/or powering electronics devices. Such a system may include a near field energy transfer mode and a far field energy transfer mode that when intelligently combined or used selectively at particular ranges yields an overall improved result. An energy transfer unit connected to a power source may transfer energy over-the-air within range of at least one mode to one or more electronic devices integrated with an energy receiving unit for converting transferred energy to usable power suitable for charging and/or powering of the electronic device. The system may intelligently manage the selection, combination and/or switching of modes as optimally determined by at least one integrated control circuit combined with a communications protocol.
