  • Patent number: 9429396
    Abstract: An electronic weapon with an installed deployment unit, from which at least one tethered electrode is launched, provides a stimulus current through a target to inhibit locomotion by the target. The wire tether, also called a filament, conducts the stimulus current. The one or more electrodes, according to various aspects of the present invention, perform one or more of the following functions in any combination: binding the filament to the electrode, deploying the filament from the deployment unit, coupling the electrode to the target, and distributing a current density with respect to a volume of target tissue. An electrode may include a spear comprising a material with integrated conductive and insulative substances (e.g., conductive fibers in insulative composite material) and a geometry to dissipate kinetic energy after impact with the target.

  • Patent number: 9182204
    Abstract: A subsonic ammunition cartridge casing having an engineered internal volume designed to allow for the introduction of precisely the amount of propellant necessary at precisely the desired location to reproducibly produce the desired projectile velocity and internal pressure is provided. The subsonic shell casing has an engineered internal propellant cavity built into the internal body of the casing itself that does not necessarily depend on the introduction of a separate volume reducing device such as tubing, filler, foam filler and the like. This ensures the integrity of the case, does not result in anything being expelled through the muzzle of the weapon other than the projectile, does not have any burning or combusting components, allows for very precise control of the internal volume and thus chamber pressure, and is economical to produce.

  • Patent number: 8376561
    Abstract: The present invention discloses a non-pyrotechnic, light emitting projectile for marking and illuminating a target. The projectile generally contains a main body having frangible side walls, at least one frangible ampoule containing chemiluminescent reactant components, a substantially incompressible filler material positioned between the frangible side walls and ampoule, and a first and second end cap. The first end cap is designed to be traversable between a first position and a second position upon impact with an object, thus provides a force sufficient to rupture the frangible side walls and ampoules. Rupture of the ampoules causes intermixing of the chemiluminescent reactant components and formation of a chemiluminescent slurry. The second end cap provides sufficient energy transfer to the chemiluminescent slurry upon impact with a target to disperse the chemiluminescent slurry radially and outwardly with respect to the longitudinal axis of the main body.

  • Publication number: 20120085259
    Abstract: A cartridge that can fire a light-weighted projectile, producing a pressure curve of the propellant gases similar to the pressure curve generated by the shot of a heavy weighted lead-core projectile. The cartridge propels the light-weighted projectile together with a capsule, which contains an inert load of high density metal powder. The capsule is divided in multiple parts, which disassemble when it leaves the firearm muzzle, spreading the metal powder in the air. The metal powder increases the mass which is accelerated by the propellant gases, keeping the pressure curve high enough to cycle a self-loading firearm mechanism. The metal powder consists of very thin particles which spreads and decelerates rapidly in the air, causing a controllable level of danger to personnel.

  • Publication number: 20120017793
    Abstract: A two piece, two-stage, rechargeable, reusable, reduced-energy mechanically operating cartridge is provided for launching a bullet of various compositions from a dedicated or modified firearm. The cartridge unit is comprised of a primary case, a piston sleeve, a propellant unit, and a bullet choice of a solid light weight material for inanimate-target applications or a “marking” version for non-lethal live-target training applications. Cartridge includes a piston sleeve and a primary case coupled together via a channel and cog locking/traveling/unlocking system. The primary case includes a substantially non-deformable jacket defining a cavity to receive a propellant unit or propellant connection and provides the channels to receive piston sleeves cogs for a locking/traveling/unlocking feature. The piston sleeve includes a substantially non-deformable jacket defining a cavity to receive configured bullet.

  • Patent number: 8061274
    Abstract: A less than lethal projectile and method of producing the same comprising of a sealed filled polymeric pouch containing a shot within. The sealed filled polymeric pouch is formed in a form, fill, and seal machine. An automatic loading ammunition machine is fed empty shell casings; the ammunition machine automatically loads the empty shell casing with pre-determined quantities of wad, primer, and gun powder, and subsequently moves the sealed filled polymeric pouch into a projectile compartment of the empty shell casing producing a fully-loaded shell casing to be loaded into a barrel of an ammunition. The polymeric pouch is capable of being inserted into various shell casings depending on the intended use thus allowing for officers and soldiers to select from an array of munitions when confronted with a situation where less than lethal means are required.

  • Patent number: 7930977
    Abstract: Non-lethal ammunition for a riot gun assembles a bi-chambered projectile body and an impact nose, the assembly being spin-stabilized and nose-heavy such that the nose will impact first at the target. The rearward end of the assembly is mounted into the forward end of a shell casing having a high-energy gas expansion chamber, the mounting forming a low-pressure chamber at the rearward end of the projectile. A cup-shaped multi-port gas diffuser plug, spaced from the projectile body, directs burnt propellant gases from the expansion chamber into the low-pressure chamber to expel the projectile at a relatively low velocity. A sleeve interiorly of the gas diffuser plug closes the ports and is degraded by the burnt gases to provide a complete burning of the propellant.

  • Publication number: 20110079164
    Abstract: A training cartridge projectile for use in either a plastic cartridge case or a conventional metal cartridge case is disclosed that contains no explosive material. The projectile has an insert having a body portion and a front end, a container overmolded onto the body portion of the insert, a frangible ogive fastened to the front end of the tubular insert; and a payload module within the ogive in front of the container carrying a non-explosive signature material for providing a visual indication of projectile impact to an observer upon projectile impact with an object. The module includes a hollow frangible ampoule containing the signature material, and a generally disc shaped base member engaging the insert and closing the ampoule. The base member preferably has a set of axially extending vanes engaging the signature material during spin-up as the projectile is accelerated through the bore of the weapon firing the projectile.

  • Patent number: 7819065
    Abstract: The cartridge-type training round consists of a projectile and a cartridge shell into which the projectile is inserted. The projectile includes a one-piece cylindrical central body (2) and a one-piece basin-shaped projectile tip (5) that is pressed onto the central body and engages a circumferential engagement bead (7) with a circumferential engagement slot (8) located in the central body (2). The cartridge shell (20) is a one-piece basin-shaped part; it is also pressed onto the central body (2) and engages a circumferential engagement bead (22) with a circumferential engagement slot (23) of the central body (2). A receiver recess (25) is provided in an approximately cylindrical projection (24) that is inserted centered from the base to receive the propulsive charge (28) and its igniter (29). The round is of simple design, and may be manufactured inexpensively owing to its simple parts that may be largely of plastic without loss of function.

  • Patent number: 7802520
    Abstract: A modified cartridge assembly including a projectile having a gas generator proximate its aft end. The projectile includes an aft closure having a cavity filled with gas generating material. The gas generating material is ignited around the time the projectile exits the weapon's muzzle. The gas generating material then burns while the projectile is in flight, spewing pressurized gas into the wake region immediately behind the projectile. The pressurized gas reduces the projectile's base drag.
