Abstract: A vacuum pump includes a fan including a rotational speed to be controlled to cool the vacuum pump, a temperature sensor, and a control device that regulates the rotational speed of the fan in dependence on a power consumption of a drive of the vacuum pump and on a temperature measured by the temperature sensor. Another vacuum pump includes an electrically driven fan, an air guide hood, and a conductor that leads from the fan to a supply connection for the fan. The conductor is connected to the supply connection via an electrical connector. The connector is separated from an air flow path, defined by the air guide hood, by a partition wall.

Abstract: A method of producing a machining segment, in which a green body (51) is constructed from a machining zone (54), wherein the machining zone (54) is produced from a first metallic powder material (56) and hard material particles (58), the green body (51) is compacted under pressure with a compression pressure to result in a compact body and the compact body is sintered thermally at a sintering temperature to result in the finished machining segment, wherein the machining zone (54) is produced by layer-by-layer application of material layers of the first metallic powder material (56) and particle layers of the hard material particles (58), wherein the hard material particles (58) in one particle layer are placed into the previously applied material layer of the first metallic powder material (56).

Abstract: The invention relates to a scroll pump comprising a pressure sensor integrated into the scroll pump.

Abstract: An electronic device with a housing for being attached to a pane of a motor vehicle by a coupling medium of flexible rubber- or gel-like material includes an exhaust duct for connecting an area of potential bubble formation between the vehicle pane and the coupling medium to ambient air. The exhaust duct prevents the permanent trapping of air bubbles during mounting of the device on the vehicle pane.

Abstract: A sensor device for detecting the degree of wetting and/or soiling of a pane or windshield arranged in a motor vehicle includes individual radiation guide elements integrally molded onto a wall of a housing to be separated from one another by a blocking element of the wall. This reduces the amount of ambient radiation from the environment. A radiation emitter and a radiation receiver are structured as SMD components which are arranged on a circuit board carrier. The sensor device created in this way has a simple and compact design.
