Abstract:

The design and development of a fluid analog to a digital conversion system are described. The system represents the digital portion of an incremental fluid control system and consists of a fluid quantizer, directionsensing circuit and four-stage binary bidirectional counter. The system operates at over 100 pulses per second. A method of quantizing an analog quantity, using a fluid as the information transmission medium, is examined and evaluated. The design of suitable fluid logic elements is described. Techniques are developed by which characteristics of these elements can be exploited for logic circuit synthesis. An engineering model is developed for predicting the dynamic characteristics of bistable fluid amplifiers. The dynamic behavior predicted by the model, in conjunction with experimental data, is used in discussing the factors that affect the speed of operation of logic circuits. Methods by which the speed of operation of logic circuits can be increased are also outlined. Author
