Abstract: A system and method that use audio feedback from a region being monitored can provide location information pertaining to fire or individuals in the region. Units of a public address system can each be equipped with a microphone. Audio from the microphones can be processed at a common location, such as an alarm control panel. The audio can provide fire profiles as well as information as to individuals in the region being monitored.

Abstract: Combining and fusing the tracking of people and objects with image processing and the identification of the people and objects being tracked. Also, conditions of a person, object, area or facility can be detected, evaluated and monitored.

Abstract: The acoustic sound of water flowing to/from activated sprinkler heads is used to identify fire location in a region(s). Acoustic transducers, such as microphones, can be located in the vicinity of sprinkler heads. Active heads, spraying water, will produce sounds of flowing water to which the transducers respond. Alternately, acoustic flow sensors can be coupled to sprinkler head feed pipes.

Abstract: A system and a method of establishing direction and velocity of fire development in a region. A fire profile based on a time sequence of alarming detectors provides both direction and velocity information. Future directions of development can be estimated by analogizing fire progression to a ball bouncing off of a rigid wall.

Abstract: An ambient condition detector incorporates an audio transducer for discrimination between alarm and non-alarm conditions. The transducer can provide occupancy information. In addition, a monitoring system can graphically present information as to the location of individuals, such as fire fighters, in the region.

Abstract: An apparatus and method monitor the operational status of one or more other systems or components. Each of the other systems has a primary operational function such as message repeating, environmental control, hazardous condition monitoring or regional security. The systems or components feedback information as to their functionality to the apparatus for analysis and presentation.

Abstract: Signals from a plurality of detectors are evaluated to establish an ingress or an egress path or paths to and from a region. Where the detectors indicate flame or smoke concentrations, the ingress paths lead first responders to the source of the flame or smoke while egress paths lead evacuees away from the flame or smoke.

Abstract: Methods and systems are provided for enhancing the air quality in buildings during a chemical and/or biological attack and/or when the air quality around a building drops to unacceptable levels. Preferably, relatively non-contaminated (clean) air is stored in one or more clean air reservoirs. Once stored, the clean air is selectively delivered to buildings when a chemical and/or biological attack is detected, and/or when the air quality around a building drops to unacceptable levels.

Abstract: Methods and systems are provided for enhancing the air quality in buildings during a chemical and/or biological attack and/or when the air quality around a building drops to unacceptable levels. Preferably, relatively uncontaminated (i.e. clean) air is retrieved from a remote location and transported to one or more buildings using, for example, a pipeline, a ship, a truck or any other suitable method. The air is provided to the one or more buildings to enhancing the air quality in the buildings during a chemical and/or biological attack and/or when the air quality around a building drops to unacceptable levels.
