Abstract: A lamp system, especially for a motor vehicle, has a casing that is covered by a clear, optically neutral lens and that contains at least one light source composed of a light bulb and an associated reflector. A screen in the form of a semireflecting mirror is positioned between the lens and the light source in such a way as to separate a posterior lamp section that accommodates the light source from an anterior lamp section defined by the screen and the lens. Consequently, to an observer looking in the direction of the light source, the posterior lamp section is indiscernible while the screen is transparent to the light emitted by the light bulb when the lamp is turned on.

Abstract: The invention refers to one of a number of nodes of a communication system. The nodes are connected to a communication media for transmitting data among the nodes. Said one node comprises a communication controller, across which the node is connected to the communication media, and a bus guardian for controlling access of the communication controller to the communication media. In order to provide a cheap but nevertheless reliable way for monitoring the synchronized clock signal of a node of a communication system and in particular for detecting deviations of the synchronized clock signal it is suggested that a synchronized clock signal from the communication controller is made available to the bus guardian, and that the bus guardian comprises means for monitoring the synchronized clock signal using a bus guardian internal clock signal, which is generated by means of an electronic circuit and which is less accurate than the synchronized clock signal to be monitored.

Abstract: In a valve-driving device for variable adjustment of the lift of a gas exchange valve of an internal combustion engine, wherein the gas exchange valve co-operates, via a transfer element, with a roller which can move about an axis of rotation, with a control path having an idling lift curve and a lift curve in an end area of a spring-loaded pivoting level which is controlled by a cam associated with a cam shaft in order to actuate the lifting of said gas exchange valve. In order to obtain a pure pivoting movement of the pivoting lever, the pivoting center of motion forms a constant instantaneous center of rotation during any actuation of said lift. In order to prevent an impact arising from the valve clearance, the control path of the pivoting lever comprises a ramp, which is correspondingly adapted to the respective valve clearance, between the idling lift curve and the lift curve.

They are then stored in the memory assigned to the control unit.

Abstract: A plastic fender has an upper first edge area and a second edge area extending at an approximately 90° angle thereto. The fender is fixed to the vehicle body in the second edge area by a screw. Furthermore, along the first and second edge areas, a plurality of spaced-apart elongated holes is provided, which admit a mounting section of a guide element which in turn is mounted to the vehicle body with a mounting screw. On the mounting sections of the guide elements, a guide edge covering, respectively, the opposite longitudinal edges of an elongated hole is provided such that, during thermal expansion, the fender can elongate unhindered. For this purpose, the longitudinal extent of the mounting section of the guide elements is shorter than the corresponding longitudinal extent of the elongated hole.
