摘要： A stator coupling for the torsionally rigid connection of two components allows radial and axial relative movements within tolerance limits has a base surface (10) with first (18.1, 18.2) and second (28) lugs. The second lugs (28) are positioned at the straight-line edges between the assembly points (26, 42). Bent edges (30, 32) parallel to one respective edge are bent away at least twice, so that a flange (34.1, 34.2, 34.3, 34.4) surface-parallel to the base surface (10) is formed. Two second lugs, are positioned at edges following one another in the peripheral direction, and overlap with mutually facing ends of their flanges and these ends each together form one of a set of second assembly points (42.1, 42.2).

摘要： A method for checking the operability of a digital signal processing unit of a position sensor, wherein the digital signal processing unit executes an instruction queue of N instructions one after another in sequences, wherein an additional number of x instructions is executed by the digital signal processing unit during each sequence, wherein the additional instructions are provided in a unit different from the memory, and that the results of the additional instructions are stored. The results of the additional instructions are read by a microcomputer. The results of the additional instructions are compared by the microcomputer with the expected results achieved by execution of identical additional instructions by the microcomputer or with expected results stored in the microcomputer. This includes a position encoder comprising a digital signal processing unit for calculating position information.

摘要： An apparatus for position determination has an optical scanning unit which is to be moved relative to a surface and which includes an image sensor for detecting light intensity patterns of light which is reflected by the surface. The apparatus furthermore has an electronic processing unit which is associated with the image sensor and configured to determine a traveled movement path and/or a movement speed of the optical scanning unit relative to the surface from a difference between light intensity patterns detected after one another in time. A further processing unit is configured to produce an intensity correlated signal which correlates with the intensity of the light reflected by the surface. An evaluation device is associated with the image sensor and is configured to recognize a graphical code pattern located on the surface with reference to the intensity correlated signal and to read out information from the code pattern.
