ABSTRACT:
An avalanche and hypothermia protective system for detecting emergency situations and instances when a user is severely compromised by adverse atmospheric and climactic extremes, e.g. entombment by an avalanche or high altitude mountaineering, and providing relief for the detected emergency situation. The system includes a sensor housing to be worn on the head of the user including sensors for sensing certain conditions and generating a signal indicative of the conditions sensed. A backpack including a microprocessor therein is connected to the sensors for analyzing the generated signal to determine if an emergency situation exists. A device for relieving the emergency condition is connected to the microprocessor for providing relief to the user upon detection of an emergency condition and to provide support for preexisting conditions such as cold induced asthma. The sensors may sense at least one of skin temperature of the user, respiratory rate of the user, an amount of oxygen in the atmosphere surrounding the user, snow weight impacting on the user and noise level. The backpack may store an oxygen supply tank and a chemical heat pack for use in automatically relieving the detected emergencies. The system also includes a signal transmitter for transmitting a distress signal upon detection of an emergency condition or upon manual activation by the user. A supply of drinking fluids may also be stored within the backpack for providing liquid refreshment to the user when desired.
