A STATISTICS ORIENTED DATA ACQUISITION SYSTEM

THIS PROPOSAL DESCRIBES AN AUTOMATIC DATA ACQUISITION SYSTEM, CONSTRUCTED WITH MULTIPLE MICROPROCESSORS, WHICH EMPHASIZES REAL-TIME ASSESSMENT OF DEVIATION FROM THE RECENT STATISTICAL HISTORY OF SIMULTANEOUSLY MONITORED SIGNALS. THE SYSTEM PROVIDES COMPUTERIZED GRAPHICS FOR REPRESENTING THESE STATISTICAL TRENDS FOR A MULTICHANNEL SYSTEM, IN REAL-TIME. THE SYSTEM WILL COMPUTE AVERAGED RESPONSES AND EVENT HISTOGRAMS, EACH WITH CORRESPONDING POINT FOR POINT VARIANCE WAVEFORMS. DATA STREAMS WILL BE REDUCED TO MOVING STATISTICAL PROFILES, AND STORED IN FORMATTED DIGITAL FILES. THIS SYSTEM WILL HAVE DIRECT APPLICATION IN THE RECORDING, REDUCTION, AND ANALYSIS OF THE LARGE QUANTITIES OF DATA COLLECTED DURING LONG-TERM CLINICAL/PHYSIOLOGICAL MONITORING. A PROTOTYPE SYSTEM WILL BE CONSTRUCTED, WITH APPROPRIATE CONTROL AND DISPLAY SOFTWARE, IN PHASE I.
