ABSTRACT:
A system connects to an external contact pad that comprises a battery, a high-impedance load element powered by the battery and connected to pull a voltage potential of an external contact pad in a particular direction; a power supply connected to receive current from an AC line, the power supply carries a voltage; a switch connected to disconnect the power supply from the AC line; logic module connected to detect a voltage transition on the external contact pad caused when a user touches the external contact pad and to selectively operate the switch when the voltage transition is detected, the logic also connected to the battery and the power supply; and at least one microprocessor connected to be powered by the power supply.
