RECURSIVE CODE SCALE Russian patent published in 2011 - IPC H03M1/22 G06F5/00 

FIELD: information technology.

SUBSTANCE: recursive code scale has an information code track made in accordance with characters of a nonlinear binary sequence with length N=2ⁿ and n reader elements lying along the information code track with an angle pitch which is equal to the value of the quantum of the information code track δ=360°/N, a second information code track made in accordance with characters of N periods of a nonlinear binary sequence with length M=2^m, and m reader elements lying along the second information code track with an angle pitch (δ+δ₂), where δ₂=360°/NM is the value of the quantum of the second information code track and simultaneously the value of the quantum of the recursive code scale, outputs of pit reader elements in total determine the output length of the recursive code scale.

EFFECT: high versatility of the recursive code scale based on nonlinear binary sequences.
