Abstract: An apparatus, system and method are disclosed for eliminating the power consumption of external electrical power adapters plugged into sources of power but detached from electrical devices they are intended to serve. The apparatus comprises a power-accessing plug, a power supply circuit, a first connector, and a second connector. The power-accessing plug is electrically connected to an external source of electrical power. The power supply circuit comprises circuitry to convert the external electrical source power into an electrical form useful for consumption by an electrical device. The first connector comprises a switch and is electrically connected to the plug and the power supply circuit. The switch (1) has an open position when the apparatus is not electrically and physically attached to an electrically powered device and (2) has a closed position when the apparatus is electrically and physically attached to the electrical device whereby current is able to flow through the apparatus.

Abstract: A remote activation system is disclosed that consumes no standby power. The system comprises a remote electromagnetic radiation transmitter able to transmit radiation having sufficient power to enable the closure of a switch. The system also comprises an electrical activation element that is electrically attached to both the on-off circuit of an electrically powered device and a source of power to permit normal operation of the device. The activation element comprises a first electromagnetic radiation power converter able to convert electromagnetic radiation power into electrical power. It also comprises a first electrically operated normally non-conducting switch that is between a source of power for the device and its on-off circuit. The remotely activated device does not draw any power when it is turned off except for optional functions such as clocks that are not related to activation.
