An Inflight Recorder Prototype for the Inflight Physiological Data Acquisition System III

摘要

A prototype for the Inflight Recorder component of the Inflight Physiological Data Acquisition System was built. The Inflight Recorder is a remote data acquisition computer for sampling physiological data. Characteristics of the recorder's design were solid-state, microprocessor controlled, expandability, 16 sensor inputs, and 122 samples per second. Demonstration of battery operation for four hours and unobstructive size characteristics awaits further testing. Following a hardware requirements analysis, the prototype was built using Complementary Metal Oxide Semiconductor (CMOS) integrated circuits. Components featured in the design were a CMOS microprocessor; Electrically Erasable Programmable Read Only Memories (EEPROM); a monolithic, 16 channel, analog to digital converter; and Magnetic Bubble Memories (MBM). In addition to building the IR prototype, several development tools have been constructed. One was a EEPROM Programmer. Another was an MBM Interactive Development System. A third was a hardware front panel for debugging IR software. User's manuals for these tools appear in appendices to the thesis.
