Abstract: An optoelectronic semiconductor chip may include a first region doped with a first dopant, a second region doped with a second dopant, an active region between the first and second regions, a first contact layer having an electrically conductive material and covering the first region. An insulating layer may cover the first contact layer and include first openings, and the insulating layer may include a second contact layer having an electrically conductive material and covering the insulating layer and the first openings. The first openings may completely penetrate the insulating layer, and the second contact layer may include second openings and/or a third contact layer comprising an electrically conductive material is arranged in the first openings in each case between the second contact layer and the insulating layer.

Abstract: An apparatus and a method for singling value documents involve a feeding device adapted to feed a respectively uppermost value document of a stack of value documents to a picking device adapted to pick the value document from the stack. A conveying device is adapted to receive the stack and to convey it relative to the feeding device. A distance sensor is adapted to detect at least one distance of the respectively uppermost value document of the stack received by the conveying device relative to the feeding device and generate at least one corresponding distance sensor signal. A control device is adapted to control the conveying of the stack relative to the feeding device and the location of the feeding device relative to the stack based on the distance sensor signal.

Abstract: An apparatus for the continuous singling of stacks of loose sheet goods comprises a singler for singling stacks of loose sheet goods and a feeding device having two feeding elements, moving stacks of loose sheet goods to be singled into a position where sheet goods are grasped by the singler and transferred to a transport system, and an area for receiving sheet goods to be singled with first and second subareas. The first and second subareas border each other, and the second subarea forms an input area for the sheet goods. The first feeding element moves within the total area, between the first and third positions, and forms an end position, at least, however, in the first subarea, between a second one and the third position. A monitoring device is provided for the first subarea for ascertaining bank notes in the first subarea underneath the first feeding element.

Abstract: A device for cooling a drive apparatus, of a motor vehicle, including a cooling apparatus through which air can flow in a throughflow direction, a redirection apparatus and a ventilator apparatus. The device includes a bypass apparatus located such that air heated by the cooling apparatus or the drive apparatus which is flowing in the direction of the cooling apparatus is at least partially induced into the bypass apparatus and prevented from reaching the cooling apparatus.
