Abstract: A power control apparatus in the form of a standard, toggle, wall-mounted light switch for remote actuation of an electrical load or local manual override. A switch housing supports and retains a latching relay that includes power terminals, a switching terminal for remote actuation by a control signal, and a manual override. A switch lever extends from the body of the switch housing for manual actuation to override the state of the relay. The switch lever engages the manual override of the latching relay upon manual actuation by a person. A centering structure maintains the switch lever in a centered position to allow unimpeded movement of the manual override. The latching relay can be remotely actuated by a signal at its switching terminal to switch a power load connected to the power terminals on or off, or the relay can be manually overridden by actuation of the switch lever.

Abstract: A method for converting heat to electricity by exploiting changes in spontaneous polarization that occur in electrically polarizable materials is described. The method uses an internally generated field to achieve poling during cycling. The internal poling field is produced by retaining residual free charges on the electrodes at the appropriate point of each cycle. The method obviates the need for applying a DC voltage during cycling and permits the use of the electrical energy that occurs during poling rather than an external poling voltage which detracts from the net energy produced per cycle. The method is not limited to a specific thermodynamic cycle and can be used with any thermodynamic cycle for converting heat to electricity by thermally cycling electrically polarizable materials. The electrical energy generated can be used in various applications or stored for later use. An apparatus for converting heat to electricity is also described.

Abstract: A method and an apparatus for over-driving a liquid crystal display (LCD) are provided, which are suitable for compensating a gray level brightness of the LCD. The method includes the following steps. Firstly, a data buffer unit outputs a current frame data. Then, the current frame data is stored into a frame memory unit, and the frame memory unit outputs a previous frame data. Next, several look-up tables (LUTs) are searched for a driving voltage in a corresponding LUT according to the current frame data and the previous frame data. Afterward, a position scanning unit receives the current frame data to determine a current position. Finally, a multiplexer outputs the corresponding driving voltage at the current position. Thus, a display panel has the same gray level brightness in upper, middle, and lower portions thereof, thereby avoiding ghosting.

Abstract: A method for converting heat to electricity is described. The method can be used to efficiently and economically generate electricity from thermal energy directly through ferroelectric or other polarizable materials without the need for first converting thermal energy to mechanical energy or to any other form of energy or work. The method can involve subjecting a polarizable material to a thermodynamic cycle having two isothermal steps and two steps that occur at constant polarization. In an ideal implementation, this thermodynamic cycle allows the conversion of heat to electricity at the ultimate Carnot limit. The ferroelectric material can be continuously cycled in and out of its ferroelectric phase while heat is continuously converted to electricity at high voltage. The electrical energy so generated can be used in a virtually unlimited range of different applications or be stored for later use. An apparatus for converting heat to electricity is also described.
