摘要:
A distance measuring device for measuring a distance of a vehicle to an obstacle and a method for testing the operation of a distance measuring system. Two measuring systems are provided, each operating according to a different measuring method. Reliable operation of the second measuring system is established when the second measuring system detects an obstacle which has already been detected by the first measuring system.

In a process for the profiling of a grinding worm (1) with at least two grinding width zones (4, 6) with differently modified thread profile for the grinding of spur and helical gears with three-dimensionally modified flank profile, the grinding width zones (4, 6) are arranged overlapping in order to gain optimum exploitation of the grinding worm width (3). In one variant, profiling of the grinding worm (1) is performed with an abrasive coated profiling gear (25) with a tooth flank geometry and facewidth differing from that of the workpiece to be ground. By suitable selection of the diagonal ratio and the allocation of the width zones (28, 29) of the profiling gear (25) to the grinding width zones (4, 6) of the grinding worm (1), it is possible to adapt the modifications of the grinding worm flanks to the requirements of the workpiece without having to alter the flank geometry of the profiling gear (25). In another variant the grinding worm (1) is profiled in a first stage across its entire width (3) with the desired profile form of the roughing zone, and in a second stage the finish grinding zone (36, 37) and the adjacent transition zones (34, 35) of the right and left flanks of the grinding worm (1) are finish profiled by means of NC controlled line by line profiling with a form dressing roll (40).

A camera system for detecting a state of a vehicle window pane is described, having at least the following: a camera having an image sensor for detecting a first radiation emitted by the vehicle surroundings and for outputting image signals; and a radiation source for emitting a second optical radiation. At least a portion of the emitted second optical radiation is detectable by the image sensor as a function of a state of the window pane. The camera system is set up in such a way that a state of the vehicle window pane is determinable on the basis of the image signals output by the image sensor during measurements in which the vehicle window pane is illuminated differently by the second optical radiation. For this purpose, an evaluation unit which determines a state of the vehicle window pane on the basis of the image signals output by the image sensor during the measurements may be provided to record the image signals and to ascertain a state of the window pane. Measurements may be carried out in particular when the radiation source is switched on or off.
摘要:
An optoelectronic module having a housing and a supporting element for optical and electronic components situated in the housing. At least one optical component is situated in the housing as well as on the supporting element. The supporting element is connected to the housing via fastening arrangements. Subsequently to assembly of the supporting element, the fastening arrangements are upset in such a way that the material of the fastening arrangement fills the recesses situated in the supporting element, thereby fixing the supporting element.

In a connection arrangement between a sensor and connection leads, only a small installation space is required. To this end, the connection arrangement has a signal amplifier, which is electrically contacted by means of bond connections with the sensor and the connection leads. This is achieved by means of connecting elements, which are designed as thin sheet-metal shaped parts and are fixed with tab-shaped end sections in a housing of plastic, in which the signal amplifier is also inserted. The end sections, the signal amplifier, and the bond connections are arranged in a space-saving manner in roughly one plane. The connection arrangement is especially suited for sensors used to measure the speed of motor vehicles.
