Classification: CPC H  B | IPC B  H

Claim 29:
30. A heating system comprising:
a first electrode and a second electrode spaced apart from one another and coupled to a surface of an object;
a return path cable in electrical contact with the second electrode, the return path cable attached to the surface of the object along a path that extends from the second electrode towards the first electrode; and
AC power control circuitry coupled to the first electrode and coupled to the second electrode by the return path cable, the AC power control circuitry configured to heat the object by supplying an AC current to the first electrode that flows along a current path within the object from the first electrode along the path, thereby, producing an effective resistance along the current path in the object that is greater than the resistance of the object to a DC current, and
wherein the AC power control circuitry is configured to measure one or more parameters of the heating system and control power transmitted to the first electrode based on the one or more parameters.
