Abstract: A motor vehicle steering system is disclosed. The system includes a steering spindle consisting of spindle members which are non-rotatably connected to one another. One end of a spindle member has a spline shaft profile and is introduced into a sleeve-like intermediate piece which is arranged on the other spindle member and, on the inner periphery, has a negative-shaped spline shaft profile with respect to the spline shaft profile such that the spindle member is plug-connected to the intermediate piece. In order for the spindle members to be able to be connected to each other with minimal effort even in the event of visual inaccessibility, a circumferential guide contour pointing toward the intermediate piece is formed on the spindle member. The guide contour is upstream of the spline shaft profile toward the intermediate piece and is perforated by grooves of the spline shaft profile to form convex guide segments.

Abstract: A method for operating a reciprocating internal combustion engine in an engine braking mode of operation is provided. The method includes closing, for a first time, at least one exhaust valve of at least one cylinder in the engine braking mode of operation within a working cycle, and opening for a first time, and closing, for a second time, the at least one exhaust valve of the at least one cylinder, and opening for a second time to thereby discharge compressed gas in the cylinder via a piston of the cylinder from the cylinder. After the first opening and before the second closing, the exhaust valve is kept open, until the cylinder is filled with gas which flows through at least one exhaust channel from at least one second cylinder of the reciprocating internal combustion engine.

Abstract: A method and a device for detecting the opening state of a garage door or the like, such as a door that restricts entry by a vehicle are provided. A control apparatus generates a predetermined light pattern. A headlight apparatus projects the predetermined light pattern onto the door, while a camera apparatus detects the light pattern projected onto the door. The control apparatus compares the light pattern detected by the camera apparatus with the predetermined light pattern and outputs information signals according to the differences between the detected light pattern and the predetermined light pattern. The differences determine the opening state of the door.
