Patent ID: 7132763

Claim:
A system for automatically interrupting power to a second device upon the extinguishing of power to a first device, the first device being adapted to receive electrical energy from an external electrical energy source, the system comprising: a power strip having at least one switched outlet adapted to receive an electrical power cord plug from the second device; a voltage sensing device that selectively detects an operating voltage used by the first device during operation of the first device, the operating voltage being less than a voltage associated with power supplied by the external electrical energy source; and a switch, coupled to the voltage sensing device, that supplies electrical energy from the external electrical energy source to the at least one switched outlet in the event that the voltage sensing device detects the operating voltage of the first device and deprives the at least one switched outlet from receiving electrical energy from the external electrical energy source in the event that the voltage sensing device does not detect the operating voltage of the first device.
