WIRELESS POWER UTILIZATION IN A LOCAL COMPUTING ENVIRONMENT
First Claim
1. A near field magnetic resonance (NFMR) power supply arranged to use a resonance channel to transfer energy to resonance circuits within a near field distance D, the distance D defining an outermost range of the NFMR power supply, comprising:
- a high frequency (HF) power source for providing a high frequency, orthogonal in-band power;
a base plate that provides high frequency (HF) power coupled to the HF power source; and
at least two “
D”
shaped resonators arranged to receive HF power from the base plate, wherein the least two D shaped resonators are driven 180°
out of phase with each other, wherein the magnetic fields produced by the at least two D shaped resonators are arranged to provide a symmetric magnetic field at a resonant frequency.

Abstract
Various embodiments of a wirelessly powered local computing environment are described. The wireless powered local computing environment includes at least a near field magnetic resonance (NFMR) power supply arranged to wirelessly provide power to any of a number of suitably configured devices. In the described embodiments, the devices arranged to receive power wirelessly from the NFMR power supply must be located in a region known as the near field that extends no further than a distance D of a few times a characteristic size of the NFMR power supply transmission device. Typically, the distance D can be on the order of 1 meter or so.
