ABSTRACT:
A logic module system utilizing a spring energy storage means having a spfic threshold level response and a constant force over a specific displacement in cooperation with a plurality of cams adapted to be moved by external forces, such as ram-air pistons, rate controlled springs, or the like. Each individual cam is profiled to present a control surface to a cooperating plunger at specified time intervals or "windows." If the combined control surfaces present at any instant in time correspond to a predetermined sequence, the system will move to an ARM condition. Absent the proper arrangement of the "windows," the system will be returned and locked in a SAFE condition.
