Abstract: A drive structure for moving an articulated control panel on a cooking appliance includes a mounting bracket fixed in position relative to the cooking appliance. A frame is movably mounted to the mounting bracket. The frame includes a guide. A curved slot is formed within the guide; the curved slot engaging the mounting bracket to travel along the mounting bracket. A control panel is affixed to the frame to move therewith. A drive mechanism is rotatably affixed to the mounting bracket and attached to the control panel. The drive mechanism includes a shaft, the shaft moveable to extend from a first, withdrawn, position to a second, extended, position in a direction substantially parallel to the control panel causing the control panel to move relative to the mounting bracket.

Abstract: Fuel cell systems and control methods including a fuel cell and a second energy source, such as a battery that is adapted to supplement the fuel cell. In addition, the fuel cell system utilizes a single bipolar switching module, such as an IGBT six pack module that is configured to implement a DC/DC converter, such as a DC/DC boost converter, for both the fuel cell and the battery. The fuel cell system also makes use of a controller that is configured to control either or both of input current and output voltage of the DC/DC converter.

Abstract: Provided is a method and apparatus for simulating the behavior and operation of a three-phase induction machine. The present invention provides for a digital simulating device for simulating the behavior and operation of three-phase induction machines in accordance with selected parameters. There is further provided a computer modeling method for behavioral and operational analysis which utilizes blocks and super-blocks connected with signals as in physical systems. The modeling method incorporates an algebraicly simplified set of equations in stationary 2-axes reference frame.
