Abstract: A cooking appliance includes a cabinet forming an oven cavity, and bake and broil heating elements. A convection system develops a flow of heated air within the cavity. The convection system includes a motor-driven fan, a convection heating element, and a controllable switch for controlling an electrical power circuit for the motor. A user interface device allows user selections of convection bake and convection roast operations. A controller communicates with the interface device and controls activations of the fan and the heating elements. The controller has an output for controlling operations of the controllable switch. During convection baking, the controller activates the bake and convection heating elements and controls the controllable switch so that the fan runs at a first speed. During convection roasting, the controller activates the bake and convection heating elements and controls the controllable switch so that the fan runs at a second, higher speed.

Abstract: In one aspect, a cooktop heating system that include a first cooktop heating element, a second cooktop heating element, and an interface device. The system also includes a controller for selectively associating the interface device with any one or both of the first cooktop heating element and the second cooktop heating element. In another aspect, the system includes at least one cooktop heating element, a potentiometer, and controller arrangement operatively connected between the potentiometer and the at least one cooktop heating element to determine heating of the at least one cooktop heating element responsive to the input provided by the potentiometer and control power provision to the at least one cooktop heating element responsive to the determination.

Abstract: A method of addressing a bistable liquid crystal material having incremental reflectance properties disposed between opposed substrates is disclosed. One substrate has a first plurality of electrodes deposited thereon facing a second substrate which has a second plurality of electrodes disposed thereon. The intersection of the first and second plurality of electrodes forms a plurality of pixels. The addressing method includes applying a predetermined number of pulses to the first plurality of electrodes, and applying a like number of the predetermined number of pulses to the second plurality of electrodes. Each of the predetermined number of pulses has a different frequency, wherein the predetermined number of pulses are applied in a set time period.
