Patent ID: 8280654

Claim:
An apparatus for a conductor capable of conducting a current, said apparatus comprising: a global positioning system device structured to determine location of said global positioning system device; a coupling device structured to couple said global positioning system device to said conductor; and a power supply structured to power said global positioning system device responsive to a current conducted by said conductor, wherein said global positioning system device is further structured to wirelessly communicate said determined location when powered by said power supply responsive to said current conducted by said conductor, wherein said global positioning system device does not wirelessly communicate when current is not conducted by said conductor, and wherein said power supply comprises a solar power supply structured to output power responsive to solar energy, a detector structured to detect said current conducted by said conductor, and a switch structured to power said global positioning system device from said output power when said detector detects said current conducted by said conductor and to remove power from said global positioning system device when said detector does not detect current conducted by said conductor.
