Abstract
Fluid logic elements are combined in various ways to provide staging, shift register and binary flip-flop functions. The elements used to provide the complex functions include a flip-flop element, sequential AND and sequential NOT elements in various combinations. For example, two sequential AND elements or two sequential NOT elements may be arranged with a single flip-flop element to provide a shift register or a binary flip-flop function. A single sequential AND element or a single sequential NOT element in combination with a single flip-flop element provide a staging function. Combinations of the multiple element devices provide enhanced control functions.
