ABSTRACT:
A method for recognizing a given pattern in a known system of pattern which contains a group of known patterns corresponding to different reference oscillation frequencies in one-to-one relation. First, a given pattern is represented in terms of a physical system capable of causing a nonlinear oscillation at a frequency corresponding to the conception inherent to the given object. The physical system is then oscillated so that the oscillation of the physical system will converge at one frequency under entrainment effect, and the converged frequency is compared with the reference oscillation frequencies of known patterns for identification of the given pattern.
