Abstract: A head-up display comprising an image generator with a light source, a tilted display, a display glass wherein the display glass has a wedged shape, a light trap, an optical system, and a transmissive screen is disclosed.

Abstract: A head-up display comprising an image generator with a light source, a tilted display, an aspheric mirror, an optical system, a transmissive screen, and an aspheric lens, wherein the aspheric lens is arranged between the tilted display and the aspheric mirror is disclosed.

Abstract: The present invention relates to a head up display system, in particular for a motor vehicle, comprising: a picture generating unit having a picture projection optics, a tilted mirror and an intermediate image plane, wherein light from the picture projection optics is deflected by the mirror toward the backside of the intermediate image plane, and an optical lens and/or mirror arrangement for magnifying and/or conveying a picture generated on the intermediate image plane to an optical combiner, wherein a pair of prisms is inserted in the optical path between the tilted mirror and the intermediate image plane to eliminate or mitigate specific light beams emanating from the intermediate image plane and traveling toward the tilted mirror and/or specific light beams emanating from the intermediate image plane already being reflected from the tilted mirror and traveling back toward the intermediate image plane.

Abstract: A welding assembly having a support part, of a material that is absorbent to a laser radiation, and an attachment part, with at least one collar piece that is transparent to the laser radiation. The support part and the at least one collar piece have a first joining area and a second joining area, which together form a joining region. The surface contours of the joining areas deviate from one another, and so, when the welding assembly is being joined together, the collar pieces are deformed while they come to bear closely against the support part. The attachment part is formed in such a way that it can be taken up by a receiving mandrel and positioned with respect to the support part and pressed against it by means of the receiving mandrel.

Abstract: The device comprises a welding unit with a tube (3), a laser radiation unit (1) radiating in direction of the tube axis (3.0), and a mandrel (4) which is connected to the tube (3) via a holding unit which is formed, e.g., by two spacer elements (5.1) and which is coaxially arranged relative to and in the tube (3). The tube (3) and the circumferential surface of the mandrel (4) are reflective of the laser radiation of the laser radiation unit (1) such that through multiple reflections between the tube (3) and the mandrel (4) the laser radiation is deflected toward the beam output-side tube end (3.2) and is shaped annularly.

Abstract: The invention relates to a mounting device for the simultaneous welding of a plurality of sensor holders along a horizontal line of a bumper. Said mounting device can be adapted to different dimensions of bumpers and has one or two freely radiating diode lasers for each sensor holder. A holding-down element is arranged downstream thereof in the direction of emission, which includes a gripper for receiving the sensor holder and a holding-down element for introducing a contact pressure, said holding-down element being permeable in partial areas for the laser radiation of the diode laser.
