Abstract: The invention relates to a method for operating an internal combustion engine operable in compression ignition mode, said engine comprising a fuel supply means, a piston in each cylinder causing ignition during compression ignition mode, at least one inlet and one exhaust valve, a control unit that controls the valve timing and fuel quantity, and at least one sensor for measuring an engine operation parameter. The following steps are performed when switching from spark ignition to compression ignition mode: controlling the exhaust and intake valves to perform a negative valve overlap to retain exhaust residual gas, determining a current combustion phasing timing, and correcting the combustion phasing by increasing the retained exhaust residual gas fraction by stepwise control of a combustion related parameter. The invention further relates to an arrangement and a computer readable device for controlling the combustion process.

Abstract: A method for controlling the material flow during the deep-drawing of sheet metal involves compressing the edges of the sheet metal (1) between at least one upper stopper (13) and at least one lower stopper (6, 7) during the deep-drawing process, with a controllable elastic force (8, 9). A corresponding deep-drawing tool is also provided. A Z-shaped blocking step (11) is stamped into the edge (1a) of the sheet metal when the upper and lower stoppers (13, 6, 7) are closed, the basic shape is then produced by deep-drawing, maintaining the blocking step (11) and completely blocking the sheet metal between the stoppers. The sheet metal (1) is outwardly stretched, and the blocking step (11) is then reduced in terms of height, facilitating the outward displacement of the sheet metal towards the outside. The deep-drawing tool has a lower stopper including an inner stopper (6) and an outer stopper (7).

Abstract: A circuit is provided to drive LEDs or diode lasers that emit light in desired wavelengths, such as the primary colors red, green, and blue, which serve as the light source for a projection display system. A display controller controls one or more series-parallel arrays of each color LED in the LED circuit with control signals to synchronize the color output of the light source with image data received from an image data source such as a personal computer. Synchronization is achieved by sending control signals to the power supply and circuit switches to sequence the color output in a single path system or adjust continuous color output in a triple path system with minimal or no reductions in the brightness of the projected image.
