Abstract:
The invention relates to a method and a device for the positionally correct winding up of a metal strip in a coiling device, the hot strip being fed to the coiling device by a driving device with driving rollers, the driving rollers being tiltable in relation to one another by a controller by means of actuators for changing the gap between the driving rollers, and the controller being fed the position of the edge of the hot strip upstream of the driving device as a measured variable and as a setpoint reference variable, an optimization of the winding result of the rolled strip coil being achieved by the surface geometry of the rolled strip being determined as a measured variable and fed to the controller.
Abstract:
The invention relates to a flatness measurement and control system for metal strip, which makes it possible to obtain improved strip or coil quality by a simple and effective measurement of departures from flatness and to control the finishing parameters through the evaluation of a line pattern on the strip surface or on the end face of a coil as it is coiled.

Abstract:
A power supply system is provided that can operate with energy storage units of varying voltages and temperatures, that can correct voltage and temperature deviations, and that can continue to provide power when an energy storage unit is inoperable. A power supply system is also provided that can recondition an energy storage unit during vehicle operation.

Abstract:
A system and method to control spark in a cylinder of a multi-cylinder engine. Spark can be controlled in a cylinder while reducing the possibility of producing a spark at a spark plug coupled to an ignition coil.
Abstract:
A bi-directional dual coil half bridge converter adapted to be coupled to a dual coil actuator of a cylinder valve in an internal combustion engine is described. In one example, the converter has a first and second capacitor and a voltage source, where the converter is actuated via switches to individually energizing coils in said dual coil actuator. A voltage regulator is also shown for maintaining midpoint voltage during unequal loading of different actuator coils in the converter.
