Abstract: A system and method are provided for facilitating automated and manual segregation of internal areas within a structure, particularly in response to active shooter warnings, or other triggering events. Embodiments may provide automated systems and methods, products and product components to facilitate simplified and automated (1) deployment of mechanized safety and/or security (bulletproof) curtains, including certain safety curtains comprising, or otherwise formed of, replaceable bulletproof and/or other penetration-resistant materials, and/or (2) actuation of mechanized safety and/or security (bulletproof) doors, to effectively segregate open areas and hallways in buildings.

Abstract: A system and method are provided for implementing advanced object collision avoidance for vehicles traveling on a constrained path, including rail vehicles traveling on tracks as a track intrusion detection system (TIDS). The disclosed schemes leverage certain commonly-installed communications nodes to provide a communication network between a plurality of laser detector scanner units, a remote monitoring facility and one or more vehicles operating on a constrained path, including a track. A detection of a track intrusion event is made by the laser detector scanner unit and communicated to the remote monitoring facility for analysis. As a result of the analysis, an automated warning may be communicated directly to a vehicle in-cab warning device and/or to fixed warning beacons on track sections in a vicinity of the track intrusion event to alert the operator of a need to take emergency action.
