A propellant mechanism for launching a projectile comprises a propellant with a detonation point at which said propellant is initially detonated which is at one end in a forward direction closest to said projectile, such that the detonation proceeds through the propellant in a backwards direction away from the projectile. A reflecting surface is provided away from said projectile for reflecting the detonation into the forward direction towards the projectile.

A firearms cartridge is provided which is equipped with a signal receiver. The signal receiver is operable to disable the firearm when it received a predetermined signal, such as a signal on the electromagnetic spectrum, acoustic signal, and the like. When the signal is not present, the firearm cartridge works like a traditional unrestricted firearm cartridge allowing a firing of the weapon.

This disclosure relates generally to a Multiple Payload Expendable Device consisting of a set of cylindrical multiple payload casings, each payload casing exhibiting circular symmetry fluid passages in relation to firing squibs and voltage coded squib actuating circuit that converts existing single payload expendable device systems to multiple payload expendable device systems.

A smart round of ammunition includes a casing, a primer disposed at a bottom portion of the casing, a projectile mounted at a top portion of the casing and a propellant disposed within an interior portion of the casing between the projectile and primer. The primer includes a piezo generator transducing a mechanical force received at a firing pin portion of the primer into a stored charge, a switch coupling and decoupling a spark gap between the stored charge and the propellant, and a wireless sensor activating the switch responsive to a digital signal received from a component external to the casing. The activation permits a discharge of the stored charge into the spark gap and therefore detonates the propellant.

Systems and methods for releasing a material into an environment. The material may be encapsulated in a receptacle or otherwise packaged for movement into the environment. The receptacle with the material inside is introduced into the environment. A triggering causes release of the material from the receptacle into the environment.

An ignition system for energetics including artillery charges includes a radio frequency transmitter and a radio frequency igniter. The radio frequency ignitor receives and converts radio frequency energy into heat or electrical energy for the purpose of igniting energetics, such as propellants or pyrotechnics. The radio frequency igniter may be applied to the exterior of the energetic container or may be integral to the container.

Ammunition for a conductive energy weapon. A receptacle includes a cavity accessible through each of a first opening in a first face of the receptacle, a second opening in the first face of the receptacle, a third opening in a second face of the receptacle and a fourth opening in a third face of the receptacle. A propellant unit is included within the cavity proximate the second opening and a projectile is included within the cavity proximate the second opening. A housing is coupled to at least the second face and the third face of the receptacle and is further configured to couple to the conductive energy weapon. The propellant unit releases a propellant into the cavity, in a direction substantially opposite the projectile's direction of flight, in response to a trigger pull of the conductive energy weapon, and the cavity directs the propellant in the projectile's direction of flight.

Life saving weapon and/or ammunition that comprises a remotely controlled firing mechanism to unlock and lock the striker remotely. The striker (S) is provided or modified with a hole or cavity (C44) which is to filled or vacated as per commands issued from remote command center, e.g., police control. The a miniature motor with gears and belt or alike mechanism may drive the motorized locking pin (ML) into the said hole/cavity, which immobilizes the striker and prevents the firing.
