Abstract: A projectile deployment system includes an entangling projectile having a pair of pellets and a tether connecting the pellets. A projectile casing carries the entangling projectile and has a pair of sockets, each socket sized to carry one of the pellets. Each of the sockets is substantially parallel with the horizontal plane and at least a portion of each of the sockets is held at differing vertical elevations when the projectile launcher is held in the firing orientation. The sockets are oriented at an acute angle relative to a longitudinal axis of the projectile casing such that the pellets travel apart from one another as they are expelled from the projectile casing. A launcher carries the projectile casing and a selectively activatable pressure source is operably coupled to the projectile casing and is capable of expelling the entangling projectile from the projectile casing toward a subject.

Abstract: A lower receiver for an AR15 type firearm is provided comprising a non-detachable magazine movable in the receiver between a first locked position where the firearm is ready for use (i.e. cocked and ready for firing) and a second non-operational position where the magazine is lowered sufficiently to open a window or aperture in the receiver enabling the user to load fresh shell cartridges into the magazine. A locking mechanism also is provided for controlling the position of the non-detachable magazine between the first and second positions. A child-proof lock further is provided to prevent undesired activation of the locking mechanism. Additionally, a novel locking plate disposed between the lower receiver's frame and the receiver's stock extension tube provides enhanced support for the extension tube and an accessory attachment point for a shoulder strap or sling.

Abstract: A launcher device for launching a 40 mm projectile (i.e., both high explosive grenades and less lethal 40 mm rounds) includes a receiver assembly, a removable buttstock, a pivoting barrel assembly, a barrel stop that limits opening of the barrel to approximately 45 degrees relative to the receiver for fast reloading, and an auto ejection assembly for ejecting spent casings out of the chamber upon opening the barrel. Individual 40 mm rounds are loaded into the chamber at the proximal end of the barrel assembly by releasing a barrel stop lever assembly and pivoting the barrel assembly open relative to the receiver assembly. The launcher further includes a hidden double action trigger group which prevents accidental firing. An arrangement of built-in picatinny rails on the barrel allow for attachment of accessories such as lights, fore grips, slings, etc.

Abstract: A missile or other flight vehicle has a stage separation mechanism for separating a downstream stage from an upstream portion of the missile. The mechanism includes one or more holes in fluid communication with a cavity between the upstream and downstream portions of the missile. The holes are located downstream of one or more shocks produced by one or more local variations in the outer surface shape of the missile. The one or more local variations in outer surface shapes produce the one or more shocks as the missile is flown at supersonic speeds. These shock(s) produce downstream pressure rises, and these pressure increases are communicated to the cavity by the hole(s). The increased pressure in the cavity provides a mechanism for separating the downstream stage from the upstream portion of the missile, after release of a mechanical coupling between the upstream portion and downstream stage.

Abstract: A multi-projectile launcher capable of firing less-lethal 40 mm rounds or high explosive 40 mm rounds (i.e., HE Grenades) can be attached to robots, drones, vehicles and stationary structures. The robot/drone multi-projectile launcher is remote controlled and capable of 360 degree horizontal rotation as well as vertical panning, and is able to quickly turn and acquire targets. A solenoid controlled firing system for each barrel includes a firing pin, trigger lever and striker, as well as a lockout bar and striker seer to prevent accidental firing (e.g., from impact or sudden jolt). Target acquisition systems include an infrared laser system, a standard red laser system, and an optic targeting system that is monitored through an onboard camera. A wireless network access device allows for remote viewing of live-feed camera images (still frame and video) and control of the optic targeting system, as well as the launcher articulation and firing.

Abstract: A lightweight linear explosive disruption tool that may be used to fire a high speed projectile at a hazardous device in order to separate the components of the explosive train, thereby rendering it safe. The linear explosive disruption tool utilizes open cellular foam materials to prevent collateral damage of explosive gases and fragmentation that would otherwise prevent the device from being fired from a robot. An internal clapper tube distributes forces to the ligaments of cellular foam material and an external support tube contains the explosive fragmentation and blast overpressure. An internal barrel provides projectile travel in a single precision oriented direction and also reduces recoil which also enables the device to be fired from a robot as well. Such a tool prevents explosive gases and fragmentation from causing unnecessary collateral damage to the surroundings or supporting robot with reduced recoil effects.

Abstract: A compensating damper comprises opposed working end faces (1788), a hermetically sealed chamber between the working end faces, and a set of plates (1701) in the chamber with a film of viscous fluid between each pair of adjacent plates. The damper has at least two different film thickness zones across the set of plates, each of the different film thickness zones providing a different resistance response when acted upon by an outside force exerted on at least one of the opposed working end faces. Multiple internal guide pins (1723) may extend axially from the opposed working end faces for engaging the plate stack partially from each of said working end faces to increase the stroke while providing for a compact damper. The plates may have a conical configuration to providing dampening in different plans.
