Abstract
PHASE ONE WILL DETERMINE THE FEASIBILITY AND PERFORMANCE CHARACTERISTICS OF A 12-CHANNEL MULTIPLEXED TRANSMITTER/RECEIVER TELEMETRY SYSTEM UTILIZING A UNIQUE MODE OF MODULATION (CONTINUOUSLY VARIABLE SLOPE DETECTION CVSD) THAT ALLOWS TRANSMITTER TO REMAIN IN A "POWER OFF" CONDITION ABOUT 90% OF THE TIME FOR A 12-CHANNEL SYSTEM (ABOUT 99% OF THE TIME FOR A SINGLE-CHANNEL SYSTEM). DVSD CONFINES TRANSMISSION TO ONLY THOSE INTERVALS WHEN A RATE OF CHANGE OF SENSORGENERATED INFORMATION IS DETECTED. TRANSMITTER HAS A DUTY CYCLE OF ABOUT 9-10% FOR A 12-LEAD SYSTEM (ABOUT 1% FOR SINGLE-CHANNEL OPERATION). THIS EXTREMELY LOW POWER CONSUMPTION GREATLY EXTENDS LIFE OF THE SMALL (HEARING-AID SIZE) BATTERY TO BE USED. CVSD ALSO GREATLY EXTENDS TRANSMISSION RANGE WHILE COMPLYING WITH FCC REGULATIONS. USE OF VSLI CIRCUITRY WILL OBTAIN A MICRO-MINIATURIZED MODULAR TRANSMITTER THAT NEEDS NO ADJUSTMENTS. SYSTEM RECEIVER WILL BE A HIGH-RELIABILITY, EXTREMELY FREQUENCY-STABLE, LOW NOISE UNIT THAT NEEDS NO ADJUSTMENT OR CALIBRATION BY OPERATING PERSONNEL.
