Abstract
Described herein are systems for wireless energy transfer distribution over a defined area. Energy may be distributed over the area via a plurality of repeater, source, and device resonators. The resonators within the area may be tunable and the distribution of energy or magnetic fields within the area may be configured depending on device position and power needs.
Claims27
A system for wireless energy distribution over a defined area, the system comprising:
- a source resonator coupled to an energy source and generating an oscillating magnetic field with a frequency,
- at least one repeater resonator positioned in a defined area and in proximity to the source resonator, and having a resonant frequency;
- and
- at least two other repeater resonators with a resonant frequency positioned in the defined area and in proximity to at least one of the repeater resonators,
- wherein the repeater resonators provide an effective wireless energy transfer area at least one of within or equal to the defined area.
A wireless energy transfer flooring system comprising:
- at least one source resonator coupled to an energy source and generating an oscillating magnetic field with a frequency,
- at least one repeater resonator positioned in a defined area and in proximity to the source resonator, and having a tunable resonant frequency;
- and
- at least two other repeater resonators with a tunable resonant frequency positioned in the defined area and in proximity to at least one other of the repeater resonators,
- wherein the resonant frequency of at least one of the repeater resonators is detuned from the frequency of the oscillating magnetic field of the at least one source to change the distribution of magnetic fields in the defined area.
A method of distributing wireless energy from at least one source resonator to a specific location within an area having tunable repeater resonators, the method comprising:
- determining a closest repeater resonators to the specific location, and
- tuning the resonant frequency of the repeater resonators to provide for an energy transfer path from the source to the closest repeater resonators.
