Abstract: A laundry appliance can be selectively operated in either manual or automatic modes of operation. In the automatic mode, a laundering operation is initiated upon receiving a single cycle input parameter from the user, preferably through a LCD touch screen display, while relying on additional operating cycle parameters established by factory preset settings or prior consumer established preferences. In accordance with a preferred embodiment of the invention, a consumer need merely select a single cycle parameter, such as a type of stain adapted to be removed, and the appliance will start based on temperature and other setting parameters taken from memory. However, even with the automatic start feature activated, the user will still be able to adjust pre-established cycle parameters by changing default values after the cycle has started.

Abstract: Methods and apparatus for controlling an engine having a first maximum power rating based on at least a first predetermined operating condition of the engine. A first sensor transmits a first signal as a function of the engine operating at a predetermined operating condition other than the first predetermined operating condition. A control device receives the first signal and transmits a power signal to the engine as a function of the first signal. The power signal may, by itself, or in conjunction with other signals, cause the engine to produce a quantity of power in excess of the first maximum power rating.

Abstract: The present invention provides methods and apparatus for controlling an electric field across a piezoelectric device. A temperature determining device transmits a temperature signal indicative of a temperature of the piezoelectric device. A control device receives the temperature signal and a first control signal indicative of a desired displacement of the piezoelectric device. The control device transmits a second control signal to the piezoelectric device as a function of the temperature signal and the control signal. The second control signal creates the electric field across the piezoelectric device, when the temperature of the piezoelectric device is below a predetermined threshold, having a magnitude above a normal operating range for the piezoelectric device.
