Firefighter locator with activator

A system for providing air to a user and activating a signal emitter for use in locating the user, said system comprising:

• an air tank having an air tank valve;
• a regulator for regulating air pressure from said air tank;
• an air line for delivering air from said air tank valve to said regulator;
• a facemask for delivering air to the user from said regulator;
• a pressure sensor coupled with said air line to monitor a pressure within said air line;
• and
• a switching means responsive to said pressure sensor to activate the signal emitter when said pressure rises above a predetermined value at the monitored location.

A wireless locator system comprising:

• a low frequency signal emitter;
• a pressure sensor for monitoring a pressure at a location;
• a switching means responsive to said pressure switch to activate said signal emitter when said pressure rises above a predetermined value at the monitored location;
• at least three mutually dispersed base station sites for receiving said low frequency signal from said signal emitter at each base station site;
• at least one phase sensing circuit for determining phase information for each received signal;
• and
• a central processing site connected in communication with each said base station site, said central processing site having a processor for using said phase information to determine the position of said signal emitter relative to each said base station site.
