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.

Abstract: A spur gear transmission has at least two toothed spur gears with toothings that are in meshing engagement with one another and which are each rotatable about an axis of rotation. An enveloping wall at least partially encloses the two spur gears in a circumferential direction and in the direction of the axis of rotation. The enveloping wall has an inner contour adapted to the outer diameters of the spur gears such that, between the enveloping wall and the spur gears, there are formed two ring-shaped gaps which transition into one another, wherein in each case one ring-shaped gap is arranged concentrically with in each case one axis of rotation. A lubricating device conducts a lubricant flow into the toothings of the spur gears. A cooling device is additionally provided, which conducts a coolant flow through one or more cooling ducts within and/or along the outside of the enveloping wall.

Abstract: A spur gear transmission with at least two intermeshing spur gears the teeth of which are in meshing engagement with one another, and each of which are rotatable via an axis of rotation. The spur gear transmission has an enveloping wall which surrounds the two spur gears in circumferential direction and in the direction of the axes of rotation. The enveloping wall has an inner contour which is adapted to the outer diameter of the spur gears in such a manner that two annular gaps which merge into each other are formed between the enveloping wall and the spur gears. One annular gap respectively is arranged at least substantially concentrically with respect to a respective axis of rotation. The enveloping wall is formed by a two-part housing which is closed along a parting line and which has an upper part and a lower part.

Abstract: Electric machine having a rotor and a stator with stator coils arranged thereon, a wiring arrangement with a conductor support element and with connection conductors arranged at the latter, which connection conductors are connected to winding ends of the stator coils inside a wiring area. The wiring area is filled with an insulating potting material. The potting material has a cable feedthrough structure in the form of a free space forming a passage through the potting material.

Each ring-shaped gap is arranged at least substantially concentrically with respect to a respective axis of rotation. The enveloping wall is formed by a multi-part housing which is closed along a parting joint. The parting joint extends partially or entirely substantially within a plane in which one of the two axes of rotation or both axes of rotation run.
