Abstract
Official abstract text for this publication.
A resonance power transmission system, and a method of controlling transmission and reception of a resonance power are provided. According to one embodiment, a method of controlling resonance power transmission in a resonance power transmitter may include: transmitting resonance power to a resonance power receiver, the resonance power having resonance frequencies which vary with respect to a plurality of time intervals; and receiving, from the resonance power receiver, information regarding the resonance frequency having the highest power transmission efficiency among the resonance frequencies used in the time intervals.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, executed by a resonance power transmitter, of controlling resonance power transmission, the method comprising: transmitting resonance power to a resonance power receiver, the resonance power having a different resonance frequency for each of a plurality of time intervals, and transmitting information about an amount of the resonance power and an identification of a resonance frequency, in each of the plurality of time intervals; and receiving, in…
