Patent ID: 8321027

Claim:
A transcutaneous power supply for an implant having a receiver coil, the transcutaneous power supply comprising: a transmitter coil external to a body; three or more satellite sensors situated peripherally in relation to of the transmitter coil, the satellite sensors being adapted to receive a signal generated by the transmitter coil, the satellite sensors being further adapted to detect a change in the signal caused by a changing position of the transmitter coil in relation the receiver coil; a control circuit electrically connected to the satellite sensors, the control circuit measuring the signal and comparing the signal to a baseline value; and three or more indicators electrically connected to the control circuit; a housing containing the transmitter coil, the satellite sensors, and the indicators, wherein the control circuit causes changes in the indicators according to the change in the signal such to cause a visual indication of a direction to move the power supply to position the transmitter coil over the receiver coil for optimal power transmission.
