Abstract: Methods and systems for supplying auxiliary electrical power to a controller during power loss are described hereinabove. The system is powered by a primary power source, and includes a controller and a winding load that are both powered by the primary power source, and a switching device. When the primary power source is disconnected from the controller and winding load, the winding load continues to residually exercise to generate residual electrical power. The second switching device then channels the residual electrical power to the controller for a period of time at an acceptable level.

Abstract: A method and an arrangement (15) for detecting the actuation of an operator-controlled element (1) make possible a reliable detection of an operator-controlled function to be activated by the operator-controlled element (1) independently of environmental and wear conditions.

Abstract: A device for creating a three-dimensional molded part (30) made from fiber material using of a multiple-part mold (1, 2) whose inside (1a, 2a) determines, at least partially, the contours of the molded part. The fibers are blown into the mold by an air flow using a plurality of nozzles (4) and the air flow then escapes through openings of the mold, so that the fibers accumulate on the inside of the mold, whereupon the fibers are optionally compressed locally before they are bonded with each other through the supply of heat and are finally taken from the mold (1, 2) as a molded part (30). The blowing direction of the nozzles (4, 24, 34) can be pivoted and the pivot axes extend close to the outside of the molded part and the fibers are blown in by the nozzles (4, 24, 34) that are activated at different times.
