Abstract: A system and method that uses one or more jet engines to remove unmanned aircraft from restricted airspace. Generally, the force created by a jet engine can be used to remove drones or other unwanted objects from the restricted airspace. Once the system determines the presence of an unauthorized aircraft or object within the restricted airspace, the jet engine(s) can be activated and used to pull the drone or flying object towards the jet engine though the force created by the intake of the jet engine(s), or to expel the drone or object from the restricted area through the force created by the exhaust of the jet engine(s).

Abstract: A method where a laser beam is configured to generate a laser-induced plasma filament (LIPF), and the LIPF acts as a decoy to detract a homing missile or other threat from a specific target.

Abstract: The present invention relates to a bullet. More particularly, the present invention relates to a bullet including concentric and sequentially ordered cylindrical fore, intermediate and aft portions. The aft portion comprises a cross-sectional diameter about equal to the diameter measured across the rifle landings of the riffled barrel operatively to create a gas pressure build up there-behind while the rifling grooves and lands deform and/or cut the aft portion thereby to impart spin to the bullet about the central axial axis thereof. The intermediate portion comprises a cross-sectional diameter smaller than that of the aft portion, which acts as a bearing surface for operatively riding along the rifling lands thereby to inhibit yawing of the bullet while operatively travelling through the rifled barrel.

Abstract: A system for alerting a user to a state of a weapon includes a safety assembly, operably coupled to the weapon and operable to selectively render the weapon into either a safe mode or a firing mode. A motor is carried by the weapon and is operably coupled to the safety assembly so as to be engaged when the weapon is in the firing mode. The motor is operable to impart vibratory motion to the weapon of sufficient magnitude that a wielder of the weapon can tactilely sense the vibratory motion without visually inspecting the weapon to thereby sense that the weapon is in the firing mode without visually inspecting the weapon.

Abstract: A concealed carry weapon (CCW) container offers a user a fail-secure locking mechanism to ensure that the CCW stays locked at all times even when there is no power. The CCW container enables the user to quickly and automatically unlock when the user utilizes the biometric recognition system, a pass code, or an RFID (Radio Frequency Identification) tag. The CCW container employs interior and exterior lighting, quick access magnetic closure with or without a locking mechanism attached, and a ballistic armor plate to protect the user's vital body parts using the ballistic armor plat as a shield. Further, a method for managing the fail-secure locking mechanism allows the user to efficiently access the CCW content using a mobile app, the RFID tag, or any other biometric technology. Additionally, the method provides a panic switch that alerts security authorities of an incident and forwarding any salient video or sound thereto.

Abstract: A digitally controlled hand-tossable explosive delivery receptacle comprises a ruggedized reusable compartment enclosing a digital circuit and a disposable cartridge holding one or more explosive chemical agents and a primer. The disposable cartridge is configured to be mounted to the ruggedized reusable cartridge, and a high-strength bulkhead incorporated into the reusable or disposable compartment that separates the digital circuit from the chemical agents. The reusable compartment is sufficiently ruggedized to withstand the ignition of the primer and the detonation of the chemical agents to be reused with one or more additional disposable cartridges. In one implementation, the delivery receptacle uses a commercial airbag initiator as the primer, which is arranged in relation to the one or more chemical agents so that when the initiator is activated, it generates a pressure wave that expels the one or more chemical agents from the grenade.
