Abstract: The present invention encompasses a system and method for automatically interrupting a flow of power from an external electrical energy source to at least one device upon the extinguishing of power to another device. The system includes a power strip, a voltage sensing device (e.g., a 5 Volt power tap), and a switch. The power strip has at least one switched outlet adapted to receive an electrical power cord plug from at least one secondary or peripheral device. The voltage sensing device selectively detects an operating voltage of a primary device, wherein the operating voltage is less than a voltage associated with power supplied by the energy source. The switch is coupled to the voltage sensing device and selectively supplies electrical energy from the energy source to the switched outlet(s) depending upon whether or not the voltage sensing device detects the operating voltage of the primary device.

Abstract: The present invention relates to an improved electrical power strip which will automatically energize and de-energize one or more devices which are plugged into the strip, upon receiving an electrical signal from the primary device, without the need for manual actuation of a switch on the electrical strip or an under monitor system by the user. This system senses the primary status of the power supply through a low voltage power tap connector which is plugged in any appropriate socket of the primary device (which may be a personal computer). The output signal triggers a synchronous transfer switch or relay which enables power to secondary devices (which may be a monitor, printer, scanner, sub woofer, modem, etc.), permitting them to be synchronously turned on or off depending on the computer system status (ON or OFF).
