摘要:
A method for beam guiding of a light beam generated by a light source to a target location along a path distance LS, comprises splitting the light beam on the path distance LS at least once into a first partial beam and a second partial beam, guiding the first partial beam additionally at least once along a delay line, the first partial beam thereby covering an additional path distance LD, guiding the second partial beam only along the path distance LS, combining the first and second partial beams after the first partial beam having passed through the delay line and guiding the combined beam to the target location, wherein the light beam is guided along the path distance LS and LD in such a way that the light beam generated by the light source has a predetermined beam width B at the target location, expanding the light beam between the light source and the target location at least once to a beam width B′>B and comprising the light beam again at least once in such a way that the light beam has the predetermined beam width B at the target location.

摘要:
Current supply means for a laser flash lamp contain a fast switch and control means which modulate the amplitude of each individual pulse with a presettable modulating frequency and depth of modulation. This permits higher peak envelope powers to be obtained at an unchanged mean power of the individual pulses so that the necessary threshold values can be better exceeded during materials processing. The amplitude modulation of the individual pulses also prevents undesirable shielding plasma from forming above the processing place.
摘要:
In a method for controlling a measuring system in a chassis measuring station, the motor vehicle is detected automatically in the measuring station by at least one detection unit and its position is ascertained with respect to at least one measuring device which is controlled on the basis of a signal of the detection unit in that an operating state of the measuring device is activated. The measuring system includes at least two mutually opposite measuring devices, which respectively have one image acquisition unit and one transverse referencing unit, and at least one detection unit, which is a light barrier having at least one transmitter and receiver.

A method for determining distances for chassis measurement of a vehicle having a body and at least one wheel includes determining a center of rotation of a wheel of the vehicle by projecting a structured light pattern at least onto the wheel, recording a light pattern reflected by the wheel using a calibrated imaging sensor system, determining a 3D point cloud from the reflected light pattern, and determining the center of rotation of the wheel from the 3D point cloud. The method also includes determining a point on the body by evaluating the previously determined 3D point cloud or by evaluating a plurality of grey-scale images recorded under unstructured illumination. A height level is determined as a vertical distance between the center of rotation of the wheel and the point on the body.

摘要:
A vehicle roof with a roof opening disposed within a fixed roof outer skin of a vehicle and a cover (10) to optionally close and at least partially open the roof opening. To at least partially open the roof opening, the cover can be both tilted out from a closed position at its rear edge and displaced in the driving direction to the rear. The cover has at least one locking lug (12a, 12b) in the region of its leading edge (14) that engages, from below in a closed position of the cover, into a support element that is stiff in a direction perpendicular to the roof outer skin. Additionally, the cover is formed at its rear edge such that engagement from below under the lateral and rear areas of the roof opening does not occur in the closed position.

摘要:
A guide device for a movable roof element of an openable vehicle roof with a guide sliding block connected to the roof element and with a guide unit which has two guide surfaces which route the guide sliding block between themselves and which are pointed in opposite directions, one of the guide surfaces being held on the guide unit to be able to move relative to the guide sliding block and being pretensioned relative to the other guide surface by a spring mechanism, the spring mechanism having at least two spring elements which are located in a parallel connection on the guide unit. Preferably, the component which contains the slide surface is supported by the first spring element on the first support site of the guide unit and by the second spring element on the second support site of the guide unit.

A ventilation cap (3) for a motor vehicle roof (1) for ventilation of the motor vehicle interior (4) and a roof with such a ventilation cap, in which the ventilation cap (3) is formed to be oblong having an air duct with a front air opening (6) and with a rear air opening (7) which discharge above the motor vehicle roof (1), the air duct being flow-connected to the motor vehicle interior (4) via a flow path which is formed in the ventilation cap (3). The motor vehicle roof (1) is formed preferably as a glass roof with at least two glass surfaces (2a, 2b), on which the ventilation cap (3) is mounted essentially a central longitudinal axis.
