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.

A method and apparatus for automatically controlling power of address data in a plasma display panel (PDP), and a PDP device including the apparatus are provided. In this method, first, a difference-sum of pixel value differences between adjacent pixels successively arranged along a column of block is calculated. Then, an address power control level corresponding to the calculated difference-sum for each block is determined. Thereafter, gain information for each block on the basis of the address power control level for each block is determined. Next, a gain for each block corresponding to the gain information for each block is output. Then, the input image signal is multiplied by the gain for each block to correct the input image signal to output the corrected image signal. Accordingly, power consumption, noise, and generation of heat are reduced, and also the brightness is improved.
