Patent ID: 7034779

Claim:
A ruggedized Self Contained Breathing Apparatus (SCBA) instrumented with electronic and passive equipment so that the instrumented SCBA can be used in augmented reality-based training in which the location and orientation of the user's head is tracked by a tracking system that has passive or active tracking system components located in the training environment, and active tracking system components carried on the person of the user, comprising: an instrumented SCBA mask adapted to be worn by a user to cover at least the user's mouth and nose, the instrumented SCBA mask comprising a breathing portion adapted to cover at least the user's mouth and nose; a head mounted display for displaying to the user an augmented reality or virtual reality image; an image shifter; a covering device that covers at least part of the breathing portion, to protect at least some of the breathing portion and at least some of the electronic and passive equipment from shock and environmental hazards; and at least three detecting elements of the head tracking system, the detecting elements directly or indirectly coupled to the SCBA, so that both the location and orientation of the user's head can be determined by the tracking system.
