Patent ID: 8294302

Claim:
A system for providing electric power and communication from a first object to a second object wherein at least one of said first and second objects is moveable with respect to the other, comprising: a) a split core transformer wherein a first transformer portion is disposed on said first object adjacent said second object, and a second transformer portion is disposed on said second object adjacent said first object, and said first transformer portion having a first core, a primary coil winding, a primary coil rectifier, a sensing coil rectifier, and a sensing coil winding, and said second transformer portion having a second core, a secondary coil winding, and a secondary coil rectifier; b) first circuitry connected to said first transformer portion; and c) second circuitry connected to said second transformer portion; wherein application of a first alternating electric current through said first transformer portion induces a second alternating current in said second transformer portion, and wherein amplitude modulation of said second alternating electric current defines a communications signal between said first object and said second object.
