A Miniature Fluidic Oscillator and Pulse Counter

This paper reviews some of the principles involved in the development of pure fluid analogs of electronic components for such applications as computation and guidance and control. It specifically discusses two devices that are in the developmental stage: a miniature fluidic oscillator and a pulse counter. The oscillator uses port sizes in the order of thousandths of an inch, making it possible to use the vibrator principle for stabilization. The counter is a reversible binary unit using stacked plane construction which enables packaging a 14-bit counter with a capacity of 16,384 units in less than 1/2 cubic inch.
