2-bit digital pneumatic microprocessor with autonomous triggers (a) CAD design of the 2-bit processor consisting of the 5-bit MSR with five D flip-flops and the 2-bit instruction register that individually controls the two valves in the target device. It produces two independent parallel outputs from serially encoded input command with the embedded auto-triggering code in order to control the inlet valves in the molecular gradient-generating device. (b) Electrical symbolic representation. (c) Depending on the input commands, the two valves were independently controlled.
