In this propose phase i sbir design effort, we will design a portable, multichannel, battery-operated device that will digitize, process, and store physiological data. It will operate in flight under high levels of g stress. The programmable device will be capable of acquiringdata at rates sufficient to record eeg and ecg waveforms. Through the use of data compression techniques, it will allow data collection and storage throughout the duration of a mission using modest amounts ofstorage memory. Its modular design will permit use of more than one device at a time in situations where very large numbers of recording channels are required. At the conclusion of the phase i effort, we will provide design details in the form of drawings of the device, schematics of the electronics, and flowcharts of software programs. We willalso provide results of tests and recommendations for the phase ii device design.
