Heat stroke, a serious and sometimes fatal illness, can occur in individuals subjected to extreme heat and humidity without protection. For the U.S. Army Research Institute for Environmental Medicine, Southwest Research Institute (SwRI) engineers developed the world’s smallest environmental heat stress monitor (HSM) for use during military training exercises.
 

The HSM (U.S. Patent 6,111,501) is equipped with sensors to measure air temperature, wind speed, solar radiation, humidity, and barometric pressure.

Algorithms contained in the HSM combine environmental readings with programmed personal data to calculate optimum work and rest cycles and hourly water intake requirements for an individual.

This innovative device is now being used by an Australian mining company to monitor the health of workers removing gold and silver from deep shaft mines.
