Abstract

For each control element or each operation the prohibited combinatory possibilities are determined. The apparatus has a supply source, a series of inputs and switches and logic calculating means. The inputs are each associated with a variable determined from the problem in a determined state. The switching circuits are used selectively to connect one or several inputs to the source. The logic circuits are each associated with a determined combinatory possibility and connected to the inputs, each corresponding to a variable in a state complementary to that of the variable in the combinatory possibility. The logic permits one to ensure that for each prohibited combinatory possibility, the logic sum of signals presented to the inputs is equal to 1.
