Energy transfer control adapted to a medical device system
First Claim
1. A method of transmitting wireless energy from an external energy transmitting device placed externally to a human body to an internal energy receiver placed internally in the human body, the method comprising,supplying by a first electric circuit, electrical pulses having leading and trailing edges to the external transmitting device, according to at least one of the following:
- varying the lengths of first time intervals between successive leading and trailing edges of the electrical pulses and/or the lengths of second time intervals between successive trailing and leading edges of the electrical pulses, andvarying the first and second time intervals to have lengths in the range of, that are in the magnitude of order of or are shorter than, a time constant of the first electric circuit, and a relationship or proportion between the lengths of the first and second time intervals, whereby, by the varying a varying power is transmitted, the method further comprising;
transmitting by the external energy transmitting device, the wireless energy generated from the electrical pulses to the internal energy receiver placed internally in the human body.

Abstract
A method of transmitting wireless energy from an external energy transmitting device placed externally to a human body to an internal energy receiver placed internally in the human body. The method comprises applying to the external transmitting device electrical pulses from a first electric circuit to transmit the wireless energy, the electrical pulses having leading and trailing edges, varying the lengths of first time intervals between successive leading and trailing edges of the electrical pulses and/or the lengths of second time intervals between successive trailing and leading edges of the electrical pulses. The method further comprises transmitting wireless energy, the transmitted energy generated from the electrical pulses having a varied power, the varying of the power depending on the lengths of the first and/or second time intervals.
