Aircrew Inflight Physiological Data Acquisition System.

Abstract

A design is presented for a self-contained, man-mounted data acquisition system to sample and store 12 environmental and physiological parameters. The design consists of one-megabyte of nonvolatile magnetic bubble memory storage, 16 analog input channels, and four digital input channels, and is controlled by a 6502 microcomputer. Operational software was designed and simulation conducted on a Rockwell System-65 minicomputer augmented with two-megabits of magnetic bubble memory. Two types of data storage methods are examined - continuous (or pulse code modulation), and three variations of delta pulse code modulation for reduction of data storage. Nonuniform sampling rates (or sampling jitter) caused by simultaneous sampling requests were investigated, and ways to reduce or eliminate the occurrence of jitter are also presented. (Author)
