Abstract
A system is presented which allows continuous monitoring of a freeswimming
diver. The Diver Monitor System (DMS) employs a diver-carried
acoustic transmitter which transmits pulses synchronized with the diver's
heartbeat. Surface personnel are able to monitor the diver's general
physical state as indicated by his heart rate and, by directional homing
with Navy hand-held sonar, can locate and recover divers in zero visibility
conditions. A continuous signal may be transmitted automatically
in the event the diver's heart stops or exceeds preset limits.
The diver's electrocardiogram signal is picked up by chest electrodes,
amplified, filtered, and waveshaped into a trigger pulse which activates
a one watt 40 kHz. sonar transmitter.
