  • System and Method for Generating Protective Obscuring Haze
    Publication number: 20160012697
    Abstract: A system and method of providing a protective cover to occupants of a room, which includes detecting an occurrence of a threatening event with a protection system deployed in the room, such as detecting gunfire with the protection system and/or receiving a transmitted command of the threatening event by the protection system, and emitting an obscuring haze into the room from a haze generator of the protection system in response to the detected occurrence of the gunfire. The emitted obscuring haze obscures the light of sight contact between a shooter and the occupants in the room, which provides a measure of cover for the occupants while other assistance is being organized. This reduces the chances that the shooter will be able to accurately shoot any victim, increasing the odds of victim survival.
