One-to-many wireless energy transmission system
First Claim
1. A one-to-many wireless energy transmission system, comprising:
- at least a resonance receiving coil; and
a resonance transmission coil having a resonance frequency and using a characteristic dimension to indicate a work range, said work range covering an area or volume larger than or equal to the total area or volume of each of said at least a resonance receiving coil, a magnetic field density within said work range of said resonance transmission coil having sufficient uniformity for each of said at least a resonance receiving coil to uniformly receive a minimum required energy to function normally without interfering each other regardless of locations within said work range;
wherein each of said at least a resonance receiving coil is further connected in parallel with a resonance frequency control element and an energy detection circuit is connected between the resonance receiving coil and a subsequent circuit;
said energy detection circuit receives a signal indicating said minimum required energy from said subsequent circuit and generates a feedback signal to control said resonance frequency control element to off-tune the resonance receiving coil so as to reduce resonance-receiving capability of the resonance receiving coil to only receive said minimum required energy to operate independently and not interfering with each other.

Abstract
A one-to-many wireless energy transmission system is provided, including a resonance transmission coil and at least a resonance receiving coil, where the resonance transmission coil has a characteristic dimension covering the area or volume larger than or equal to the total area or volume of all of the at least a resonance receiving coil. The one-to-many wireless energy transmission system can further include at least a controllable off-tune relay coil, which is placed within the work range of the resonance transmission coil. The characteristic dimension, resonance frequency and placement location of the at least a controllable relay coil are adjusted in accordance with the characteristic dimension and resonance frequency of the resonance transmission coil so that each of the at least a resonance receiving coil can receive sufficient transmitted energy uniformly within work range of resonance transmission coil to operate normally without interference with each other.
