Aircrew Inflight Physiological Data Acquisition System II.
Abstract
This paper discusses a second generation microprocessor-based prototype system to acquire, analyze, and store selected environmental and physiological data from a pilot during flight. The Aircrew Inflight Physiological Data Acquisition System (IFPDAS) II consists of an input multiplexer and analog-to-digital converter, a heart rate detector, a microprocessor, and a permanent memory device. The microprocessor's operating system monitors eight sensors, extracts desired information, and stores these reduced in permanent memory. After the flight these data are transferred to a land-based computer which completes the data processing and graphs the following environmental and physiological information versus flight time: (1) cabin absolute pressure, (2) cabin altitude, (3) Z-G's, (4) heart rate, (5) breathing rate, (6) minute ventilation volume, (7) inspired oxygen quantity, and (8) expired oxygen quantity. The completed IFPDAS II prototype provides the desired information well within the required accuracy.
