PSEUDO-RANDOM CODE SCALE Russian patent published in 2022 - IPC H03M1/24 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology. The pseudo-random code scale contains an information track, made in the form of gradations of a pseudo-random binary sequence of the maximum length of the period М=2ⁿ-1, built using a primitive polynomial h(x) of degree n, where n is the capacity of the scale, n are informational and (k+k_t+6) corrective reading elements placed along the information track with angular steps that are multiples of the scale quantum δ=360°/М, with the possibility of obtaining from them M different (n+k+k_t+6)-bit code combinations, which is a corrective code with the possibility triple correction and quadruple error detection, the outputs of the read elements are the outputs of the pseudo-random code scale.

EFFECT: increasing the information reliability of the pseudo-random code scale by generating a correction code from it with the possibility of correcting triple and detecting quadruple errors.
