Filed:

Jul 25, 2008

Appl. No.:

12/180411

Inventors:

Richard G. DuBose - Scottsdale AZ, US
Walter Thornton - Phoenix AZ, US

Assignee:

iGo, Inc. - Scottsdale AZ

International Classification:

H01H 3/42

US Classification:

307126

Abstract:

In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a wall plate system during idle conditions is provided. In an exemplary embodiment, a wall plate system is configured for reducing power during idle mode by disengaging at least one outlet from a power input. A wall plate system may include one or more outlets and one or more wall plate circuits, with power input connected to the outlets through the wall plate circuit(s). The wall plate circuit may include a current measuring system, a control circuit, and a switch. The current measuring system provides, through the switch, an output power signal that is proportional to the load at the outlet. If behavior of the current measuring system indicates that an outlet is drawing substantially no power from the power input, the switch disengages the power input from the outlet.

Abstract:

In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a power strip is provided. In an exemplary embodiment, a power strip is configured for reducing or eliminating power during idle mode by disengaging an outlet from power input. A power strip may include two or more outlets and two or more outlet circuits, with AC power input connected to the outlets through the outlet circuit(s), which may include a current transformer, a control circuit, and a switch. The current transformer secondary winding provides an output power level signal proportional to the outlet load. If behavior of the current transformer secondary winding indicates that the outlet is drawing substantially no power from the AC power input, the switch facilitates disengaging of the current transformer primary from the outlet.

Abstract:

In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a power module during idle conditions is provided. In an exemplary embodiment, a power module is configured for reducing power during idle mode by disengaging at least one power output from a power input. A power module may include one or more power outputs and one or more power module circuits, with power input connected to the power outputs through the power module circuit(s). The power module circuit may include a current measuring system, a control circuit, and a switch. The current measuring system provides an output power level signal that is proportional to the load at the power output. If current measuring system behavior indicates that a power output is drawing substantially no power from the power input, the switch disengages the power input from the power output.
