Patent ID: 8600517

Claim:
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: applying from a first electric circuit to transmit the wireless energy, to the external transmitting device at least one of: electrical pulses having leading and trailing edges, and electrical pulses forming a pulse train when the electrical pulses are forming a train of two or more electrical pulses supplied in a row, the train having a first electrical pulse at the start of the pulse train and having a second electrical pulse at the end of the pulse train, the second pulse having a trailing edge and the first pulse having a leading edge, 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, the lengths of second time intervals between successive trailing and leading edges of the electrical pulses, or the lengths of first time intervals and second time intervals between successive trailing and leading edges of the electrical pulses, and varying the lengths of the second time intervals between successive trailing edge of the second electrical pulse in a first pulse train and leading edge of the first electrical pulse of a second pulse train, the method further comprising: transmitting wireless energy, the transmitted energy generated from the electrical pulses or pulse trains having a varied power, the varying of the power depending on the lengths of the first time intervals, second time intervals, or first and second time intervals, receiving by the first electric circuit external to the human body wirelessly transmitted feedback information from the energy receiver internal to the human body, the wireless feedback information being related to the level of the power of the transmitted wireless energy as received by the receiver, for varying the first time intervals, second time intervals, or first and second time intervals to vary the transmitted wireless energy in response to said feedback information, forming a circuit formed by the first electric circuit and the external energy transmitting device having a first characteristic time period or first time constant, and varying effectively the transmitted energy, having an effective frequency time period in the magnitude of the first characteristic time period or time constant, or shorter.
