SEALINK - A MULTICHANNEL TELEMETRY SYSTEM TO MONITOR DIVERS

BIO-TELEMETRY FROM PEOPLE IN AN UNDERSEA ENVIRONMENT IS CONSIDERABLY MORE DIFFICULT AND MORE COMPLEX THAN THE TASKS OF MONITORING MEN IN SPACE OR ON EARTH. THIS PROJECT ADDRESSES THESE DIFFICULTIES AND COMPLEXITIES. A PROTOTYPE MULTI-CHANNEL, UNDERWATER TELEMETRY SYSTEM WITH THE CAPACITY TO MONITOR 8 CHANNELS OF PHYSIOLOGICAL DATA FOR AT LEAST 8 HOURS FROM AN UNTETHERED COMBAT SWIMMER OPERATING AT A DEPTH OF UP TO 300 FEET HAS BEEN DESIGNED. THE MONITORING STATION MAY BE LOCATED UP TO 5 MILES AWAY FROM THE SITE OF ACTUAL DIVING OPERATIONS. THIS SYSTEM DESIGN ALSO PRESENTS THE CONCEPTS AND CONSIDERATIONS REQUIRED TO EXPAND THE SYSTEM CAPACITY TO ENABLE ACQUISITION, MONITORING AND DISPLAY OF DATA SIMULTANEOUSLY FROM UP TO 6 UNDERWATER SUBJECTS.
