Abstract: A method for controlling a planar drive system includes generating a position allocating function, in an allocation generating step; measuring a plurality of measuring values of the magnetic rotor field by magnetic field sensors for a position of the rotor relative to the stator module, in a magnetic rotor field determining step; applying the position determination function to the plurality of measuring values of the magnetic rotor field of the plurality of magnetic field sensors, in a measuring value analysis step; and determining the position of the rotor relative to the stator module on the basis of the measurements of the magnetic rotor field measured by the plurality of magnetic field sensors and based on the allocations of the position allocating function, in a position determining step. The application further relates to such a planar drive system.

Abstract: A method for detecting optical codes comprises an input image being provided. Optical codes in the input image are detected by generating an output image on the basis of the input image. Within generating the output image, pixels of an area of the input image comprising a part of an optical code are assigned a first intensity in the output image. Within generating the output image, pixels of an area of the input image e.g. comprising no part of an optical code are assigned a second intensity in the output image. Regions of the output image with the first intensity are provided for determining properties of the detected optical codes.
