Systems and methods are provided for facilitating automated and manual segregation of internal areas within structures in response to active shooter warnings, or other triggering events. Embodiments may provide automated systems and methods, 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. Exemplary embodiments may: (a) limit lines of sight of a perpetrator; (b) interdict bullet flight paths; (c) restrict or eliminate a perpetrator's freedom movement; (d) confine areas of detected explosive ordnance detonations or dispersal of contaminants; (e) provide a means of trapping/isolating a perpetrator; and/or (f) provide local safe havens in active shooter, gunfire, explosive detonation, contaminant dispersal, and like threat scenarios/situations.

The present invention is generally related to paint ball firing devices. More specifically, the present invention is related to paintball land mines, which can fire multiple paintballs simultaneously and methods of making and using same. Furthermore, the present invention is capable of allowing the device to be disassembled (i.e., field serviceable) and provides a range of combustion chambers, barrel assemblies, and cartridges to be used in the device. In this manner, a wide range of projectile types and feet per second (f.p.s.) projectiles can be used in the device.

This invention is a gunshot detection device that provides very reliable inside and outside real-time situational awareness of gunshot events, while reducing Gunshot Detection False Positives and Negatives.

In one embodiment, a safety trailer has semi-tractor hitches at both ends and a safety wall that is fixed to one side of the trailer. That side, however, can be changed to the right or left side of the road, depending on the end to which the truck attaches. A caboose can be attached at the end of the trailer opposite the tractor to provide additional lighting and impact protection. Optionally, the trailer can be equipped with overhead protection, lighting, ventilation, onboard hydraulics, compressors, generators and other equipment, as well as related fuel, water, storage and restroom facilities and other amenities.

A transparent display provides eye protection from lasers and other high intensity light sources. The transparent display allows users to view objects clearly through the display while also presenting text, graphics or video on the display surface. Simultaneously, the display assembly comprises a component that provides eye protection against high power radiation sources. The transparent display with eye protection provides both protection from high power light sources and an additional cockpit display surface for presentation of information including graphical images, symbology, video, text, and other data.

A submergible marine barrier protecting marine installations in a protected zone against intrusion and providing a containment barrier against spread of floating spills or bodies. The body of the barrier is supported above water by a main body thus preventing intrusion and containing floating spillage. A weight in main body keeps the barrier upright, and a rigid floatation chamber in the main body keeps it afloat when full of air. A skimming pipe collects floating pollution. Flooding the floatation chambers causes the barrier to submerge allowing access to the protected zone and protecting the barrier from storms. Body, main body, and floatation chambers are made of extruded material with flotation properties (e.g. plastic pipes). Floatation chambers are connected by air hoses and have air venting tubes at their bottom. Sensors detect approaching intruders and pollution, while spikes, barbed-wire and diver-net or any known barrier are used to stop them.
