Abstract: A method for operating an electric motor that drives a displacement pump stage to deliver a liquid through a hydraulic system to supply the liquid to at least one consumer. A periodically repeating pressure fluctuation of the liquid that occurs during delivery operation is at least partially compensated by virtue of the rotational speed of the electric motor being manipulated in accordance with the periodically repeating pressure fluctuation.

Abstract: A distributing device having a housing having an inlet connection and a plurality of outlet connections, and an electromotively drivable, rotatably adjustable distributor which is arranged therein in the form of a disk, on which a liquid receiving and liquid guiding device is formed. The distributing disk is rotatably adjustable into defined positions relative to the housing.

Abstract: A control unit for a vehicle is configured to determine, during an approaching manoeuvre of a distance controller and/or cruise controller of the vehicle towards a vehicle in front, whether or not the vehicle will overtake or can overtake the vehicle in front during the approaching manoeuvre. Furthermore, during the approaching manoeuvre, the control unit is configured to adjust a behaviour of the cruise controller and/or adaptive cruise controller of the vehicle on the basis of the above determination.

Abstract: A system and method for creating secure software code. Original code is processed to determine memory states, which are dynamic during execution of the code. Selected functions of the code are duplicated and placed in parallel alternative control paths in order to create protected code with increased path diversity. The state of the memory, or a variable derived therefrom is used to select one of the alternative paths during execution of the protected code.
