An implantable device is provided, for wirelessly receiving energy pulses, monitoring the energy storage, and transmitting a first sufficient energy signal if the energy storage exceeds a first maximum value. An associated energy transmission device is provided, for wirelessly transmitting a plurality of successive energy pulses transmitted at a first power level, pausing energy transmission immediately after the first sufficient energy signal is received, and subsequently resuming energy pulse transmission at the first power level if no further sufficient energy signal is received. |
