  • Patent number: 8336459
    Abstract: A pen flare may be adapted for firing from a weapon having a caliber larger than a caliber of the pen flare. The adapted flare may be fired from a conventional shotgun. The adapted flare may include a pen flare with a portion having external threads and a base. The base may include an extractor rim and a through-bore with internal threads. The pen flare may be fixed in the through-bore of the base via the external and internal threads. A rear portion of the base may have an outer diameter that is greater than an outer diameter of a front portion of the base. A cylindrical sleeve may be disposed around the front portion of the base and around the pen flare. A conventional shotgun may be reversibly converted to a compact, lighter weight shotgun with a kit. The converted shotgun may be more desirable for firing flares.

  • Patent number: 8326461
    Abstract: A system for providing autonomous capabilities to a radio-controlled robot, comprises two communication boxes, one connected to the robot and the other connected to an operator control unit (OCU). Each communication box comprises two radios that are interoperable with preexisting data radios in the robot; a microprocessor unit; and bidirectional attenuators. The system further comprises a software application that runs on the microprocessor unit of each communications box, to integrate data into existing transmission data stream between the robot and OCU, via preexisting data radios. The system enables the issuance of additional commands besides those issued by the OCU, using the original OCU.

  • Patent number: 8316772
    Abstract: The invention describes a wall breaching explosive fragmentation ammunition and further a warhead having means for efficiently penetrating concrete and masonry walls, effectively delivering an explosive fragmentation case payload with minimum structural damage to the ammunition's projectile body. The effective wall breaching is achieved using an ogive-shaped, high strength, light weight boron carbide ceramic nose cone cap disposed adjacent to a tungsten alloy nose insert, at the fore of the ammunition. The projectile body is generally cylindrically shaped, preferably made of steel or aluminum to withstand expected forces in the launch environment. The ogive-shaped nose cone may be secured circumferentially to the projectile body with a rubber O-ring to ensure a tight seal.

  • Patent number: 8297167
    Abstract: A reciprocally-cycled, externally-powered weapon may include a rotative driver connected via a crank and connecting rod to the operating group of the weapon. The connecting rod may be connected to a pinion that meshes with a translating rack and a stationary rack. The translating rack may be connected to the operating group, and the stationary rack may be fixed to the receiver of the weapon. The energy needed to fire the weapon may be supplied by an energy generator. The minimum amount of energy supplied by the energy generator may be independent of the speed of translation of the operating group and may be sufficient to reliably result in cartridge ignition, thereby providing an infinitely adjustable firing rate.

  • Patent number: 8272330
    Abstract: A fragmentation warhead includes a cylindrical body, a pair of concentric cylindrical liners made of plastic, and an explosive charge disposed within the innermost liner. The innermost liner includes patterns formed thereon of recessed areas and solid liner elements. The outermost liner's interior surface includes patterns formed thereon of raised areas and solid liner elements. The outermost cylindrical liner is arranged to be adjustable relative to the innermost liner through rotation or translation. The explosive charge is disposed adjacent to the interior of the innermost cylindrical liner. Upon detonation of the explosive charge and because of the random dampening and temporal delay in transmitting the detonation energy through various locations of the randomly aligned cylindrical liners, the warhead body is caused to shear and break into fragments with different sizes.

  • Patent number: 8272314
    Abstract: An auto-loading firearm may obtain improved firing precision by using stored energy to cycle the firearm. The firearm may be partially cycled when the trigger is pulled. The firearm may be completely cycled only when the trigger is released. Sound suppression and/or sound reduction may be obtained by limiting the amount of gas escaping the breech during extraction as well as separating the noise of the firing event from the noise of the action cycling.

  • Patent number: 8272329
    Abstract: The dynamically configurable controlled fragmentation insert mechanism of this invention includes an assembly of three or more sleeves with differing through hole patterns thereon, that fit inside the shell casing. The individual sleeves can move independently of one another and a simple pinning mechanism holds the parts in place for a selected configuration. The warfighter can realign the insert sleeves by to create different geometric patterns of holes, each designed to engage a different target set with optimally sized fragments. The aligned patterns of holes creates individual geometric shapes that focus high-velocity jets to cut into the steel shell casing to correlate to the through-holes in the aligned patterned sleeves. Realigning the insert sleeves changes the through-hole pattern to produce different fragment sizes and mass distributions.

  • Patent number: 8250987
    Abstract: A Kinetic Energy penetrator round is shown effective in neutralizing incoming air borne threat munitions such as rockets, artillery, or mortars for instance, without posing a threat in urban environments to harm bystanders on the ground. There are also no hazards or expense with this round of cleaning up unexploded ordnance, which might have occurred with other types of rounds due to unreliability of self destruct mechanisms. Shown herein is a kinetic energy penetrator for air defense that merely self destructs beyond its operational range into fragments that are not lethal to personnel on ground; no pyrotechnic or energetic materials means are used to activate this self destruct process. A full bore projectile structure is shown that is composed of plural axi-symmetric circular disks stacked on each other and tied by a shape memory metal wire of Nitinol. While operational as a joined group, the disks are a formidable round to kill an incoming air target.
