Abstract: In an optical position measuring device for determining the position of two objects movable relative to each other along a measuring direction, a measuring standard includes a reflective measuring scale extending along the measuring direction and having scale regions with different reflectivities. A scanning unit arranged at a scanning distance relative to the measuring standard. Light source(s) and a detector arrangement including optoelectronic detector elements arranged periodically along the measuring direction are also provided. A signal processing unit is adapted to generate position signals relating to the relative position of the objects from the photocurrents generated by the detector elements, to determine a total photocurrent in a middle region and edge region(s) of the detector, and to determine the scanning distance from the photocurrent ratio of the total photocurrents formed in the middle region and edge region(s) of the detector.

Abstract: A device for determining a position of a vehicle includes a camera system, a digital headlight system having a left digital headlight and a right digital headlight, and a data processing unit. The data processing unit is configured to assign a first detected reflected light beam by the camera system to the left digital headlight with a first angle, assign a second detected reflected light beam by the camera system to the right digital headlight with a second angle, and trigonometrically determine a distance of the vehicle from a charging module in a direction of a longitudinal axis of the vehicle and an offset in a transverse direction with respect to the longitudinal axis on a basis of the first and second angles and a distance between the left digital headlight and the right digital headlight.

Abstract: A method for controlling a charging station for charging vehicles in which a first charging unit of the charging station is coupled to a second charging unit of the relevant vehicle for transmitting current. When one of the vehicles is charged, an update operation of the charging station is performed, in which a control assembly of the one vehicle transmits a current software packet to a control device of the charging station.

An inflection point of the plate may be arranged in a region from 10% to 80% of a height difference between the intermediate region and the respective groove base.

Abstract: A position-measuring device for determining an absolute position includes a measuring scale and a scanning unit that is movable relative to the measuring scale along at least one measuring direction. To generate a scannable signal pattern, the measuring scale has a measuring graduation which includes a raster of stripe elements arranged along the measuring direction at a measuring-scale longitudinal period. For the encoding of an absolute position, the stripe elements have a periodic structure having a measuring-scale transverse period along a transverse direction that is oriented perpendicular to the measuring direction. For scanning the signal pattern, the scanning unit has a two-dimensional detector system having a plurality of detector elements, which includes multiple detector columns having a plurality of detector elements in each case.

Abstract: A gas-cooled heat exchanger, in particular a direct intercooler, for cooling of a fluid which flows through the heat exchanger, with a heat transfer block featuring a plurality of flow channels, with a first collection chamber and a second collection chamber. The collection chambers are fluidically connected with one another via the flow channels and the outside of the heat transfer block can be perfused by gas. In the direction of the perfusion, a screen is arranged in front of the heat transfer block for the prevention of flow in certain areas around the flow channels of the screen. One of the collection chambers features a vent for discharge of condensate of the fluid which can be sealed from or released into the surrounding area of the heat exchanger.

Abstract: A method for bonding two partially form-fitting surfaces of two metal bodies which contain the same metal is carried out by generating a first layer on the surface of a first one of the two bodies, the first layer containing a mixture of the metal and the oxide of the metal; generating a second layer on the first layer, the second layer containing the metal but less oxide of the metal than does the first layer; placing the partially form-fitting surfaces of the two metal bodies adjacent to each other; heating the bodies placed adjacent to each other to a temperature which lies in a target range below the melting point of the metal and above the eutectic temperature of the eutectic of the metal and the metal oxide; and holding the temperature within the target range over a predetermined or a controllable duration of time.

Abstract: The invention relates to a heat exchanger for motor vehicles, especially for utility vehicles. The heat exchanger can include a heat exchanger unit that includes tubes having tube ends and ribs disposed between the tubes, and collecting tanks disposed on both ends and produced by internal high pressure forming for introducing and discharging a medium. The collecting tanks can include bottoms with openings for receiving the tube ends, covers, and inlet and outlet tubes.
