Determination of a position code

Method for determining of the present invention relates to position of computer, a claimed is an and a code on the surface of the method, a code for code to several of a surface. Using a cyclic, wherein the sequence each of the first predetermined length digital sequence the position in sequence without the different meanings determining. The sequence print on the surface repeatedly, and different end of shift of the first cyclic system, so the displacement of the adjacent sequences. The surface is composed of multiple code window, wherein the code window and a sequence to part comprises at least three sequences is a adjacent code window sequence. With a tool of a code window the displacement of the cyclic serial coding to window's of the X direction for code. The second sequence is used in THE direction code. The invention also relates of fix's method and device and apparatus for) is provided with a method the device and computer program product.
