As the structure of discriminator in the current micro-electromechanical system combination lock is complex and the reliability of electronic combination locks is poor,we designed an N bit in-situ sputtering single-try discrimination circuit to solve these problems.The N bit discrimination circuit is composed of 2 N(N-stage,two switches per stage)sputtering type OFF-ON switches and formed by alternative logic of each stage and N-stage series.The sputtering type OFF-ON switches(the one-way switch of the OFF ...
