Embodiments of the invention include a drone system or method for distracting a threat with a light source. In some embodiments, an environment can be scanned with a sensor that produces sensor data. A threat within the environment can be identified from the sensor data, and the location of the threat can be determined. The light source can be aimed toward the threat; and light may be directed from the light source toward the threat.

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.

A counter-swarm firework includes a shell casing, multiple streamers positioned in the shell casing, a burst charge positioned in the shell casing and configured to disperse the multiple streamers from the shell casing when discharged, a pusher plate positioned in the shell casing between the burst charge and the multiple streamers, a fire suppressant layer positioned between the burst charge and the pusher plate, and a kick charge configured to launch the shell casing and its contents prior to discharging the burst charge. The fire suppression layer may be configured to suppress heat generated by the discharge of the burst charge.

A method comprising the steps of propagating an infrared laser pulse in air, self-focusing the laser pulse until the laser reaches a critical power density, wherein molecules in the air ionize and simultaneously absorb a plurality of infrared photons resulting in a clamping effect on the intensity of the pulse, wherein the laser pulse defocuses and plasma is created, causing a dynamical competition between the self-focusing of the laser pulse and the defocusing effect due to the created plasma, the laser pulse maintaining a small beam diameter and high peak intensity over large distances, creating a plasma column, repeating the above steps to create a plurality of plasma columns, creating a parallel linear array with the plurality of plasma columns, and using the array to deflect an incident energy.

A system for protecting and alerting individuals in indoor environments of active shooter incidents includes a foldable shield wall, a bulletproof door panel, a foot bolt, an early warning blue light system (EWBLS), and at least one key fob. The foldable shield wall, the bulletproof door panel, and the foot bolt are mounted adjacent to each other. The foldable shield wall is mounted to a structural wall of a room, wherein the room is within a building, so that the foldable shield wall functions as a barrier between the victims and active shooter. The bulletproof door panel is mounted onto a main entry door of the room. The foot bolt is mounted onto the main entry door. Both the door panel and the foot bolt reinforce the existing entry door to withstand gunfire and force entry. The at least key fob is communicably coupled with the EWBLS.
