Abstract
A control system (FIGS. 2, 3, 5, 6) and method in which multiple levels, or stages (128, 130, 132), of logical decisions are made by selectively feedforwarding output signals (356) from control modules (72) to the inputs of other modules (80), preferably through use of control modules (233) with selective feedforwarding circuits (239, 240) to logically combine during selected synchronous time slots (351) of a synchronous clock signal (FIG. 11) the result of a plurality of nonconcurrent input signals from a plurality of input devices (28, 30, 32, 34) to control an output device (26).
