GENERAL PURPOSE MULTI-CHANNEL MEDICAL TELEMETRY SYSTEM

THIS PROJECT WILL DESIGN AND TEST A MINIATURE, LOW-COST, GENERAL-PURPOSE DIGITAL MEDICAL TELEMETRY SYSTEM TO REMOTELYMONITOR PATIENTS. THE TRANSMITTER INPUTS WILL BE ABLE TO RECOGNIZE AND INTERACT WITH THREE DIFFERENT SIGNAL TYPES, SOTHAT SENSOR TYPES AND DATA RATES CAN BE SIMPLY MODIFIED FOR DIFFERENT APPLICATIONS AT THE INITIATION OF MONITORING. MULTIPLE TRANSMITTERS CAN BE APPLIED TO THE SAME SUBJECT OR DIFFERENT SUBJECTS. THE RADIO RECEIVERS WILL BE SENSITIVE ENOUGH TO ALLOW REMOTE MONITORING AT RANGES FROM 10 TO 500 METERS, DEPENDING UPON DATA RATES. THE TELEMETRY DEVICE WILL BE INTERFACED TO A COMMERCIALLY AVAILABLE, MULTICHANNEL, ALL SOLID-STATE PHYSIOLOGICAL MONITORING SYSTEM. THE SYSTEM WILL BE TESTED AND VALIDATED BY USING FOUR DIFFERENT SENSORS: (1) A NONINVASIVE AUTOCALIBRATING RESPIRATION SENSOR (PRESENTING TWO CHANNELS OF TIME-VARYING FREQUENCY); (2) A NONINVASIVE OXIMETRY SENSOR (PRESENTING A DIGITAL SIGNAL FROM A MICROPROCESSOR INTERFACED TO AN OXIMETRY FINGER PROBE); (3) AN EKG SENSOR (PRESENTING A TIME-VARYING VOLTAGE); AND (4) A SILICON, MICROMACHINED, MULTIPLE-AXIS, LOW-G ACCELEROMETER (ALSO PRESENTING A TIME-VARYING VOLTAGE).
