  • Patent number: 8505434
    Abstract: A fire guidance device for a hand fired weapon is suitable for day and night deployment for large caliber and slow flying ammunition or missiles, such as, for example, 40 mm grenade throwers and anti tank weapons. The fire guidance device also serves to determine and automatically adjust a set-up angle for adjustment of ballistics, and a lateral angle for spin correction. The fire guidance device is attached to the weapon so it can be tilted automatically or manually and twisting is thereby dependent upon a required set-up angle of the weapon so that direct view, by the operator, to the target is preserved. For spin correction, a defined angle in horizontal orientation is adjusted between axes of the fire guidance device and the weapon. Alternatively, the fire guidance device is mounted vertically and a required cant (tilt) is then indicated in a display, followed by tilt adjustment.

  • Patent number: 7707762
    Abstract: A modular integrated rail system for a firearm includes an upper hand guard having a dovetail rail extending longitudinally between the forward end and the rearward end thereof. The rearward end of the upper hand guard includes a clamp that removably secures the upper hand guard to the barrel nut of the firearm. The rearward end of the upper hand guard and the clamp include clamping surfaces configured to cooperatively engage the outer surface of the barrel nut. The upper hand guard further includes mounting channels that are used to mount accessories, such as a lower hand guard or a grenade launcher, to the upper hand guard. The rear end of the upper hand guard includes alignment tabs for automatically aligning the dovetail rail of the upper hand guard with the dovetail rail of the upper receiver during mounting. The tabs also prevent rotation of the rail system relative to the upper receiver during use.

  • Patent number: 7690310
    Abstract: A high-pressure fixed munition for a low-pressure launching system having a cylindrical body with a centrally located bore is provided. The bore of the munition has a reduced diameter on the charge end in which a primer charge is positioned. The bore is filled above the primer charge with a propellant and above the propellant with a payload. The payload may include multiple buckshot pellets, frangible buckshot pellets, tear gas, multiple slugs, frangible slugs, paint balls, rubber pellets, bean bags, or the like. The munition may also include a pressure disk between the propellant and the payload, and tactile ridges or on the outside surface of the munition body or be of a specific color for purposes of identification of the payload.

  • Patent number: 7526999
    Abstract: The present disclosure relates to a less-lethal projectile device generally comprising a projectile, such as a rubber-encapsulated metal block, that is mated to a docking base by way of a mounting tube. The projectile may be milled with a cavity located in its rearward section for enabling the projectile to fit onto the mounting tube portion of the docking base through compression. The projectile captures a fired bullet and is propelled along the original path of the bullet. The disclosed system results in a normally lethal weapon being converted into a less-lethal blunt impact system.

  • Publication number: 20080291075
    Abstract: A defensive aids suite for light armored vehicles utilizes four complementary sensor technologies including: visible and infrared optics, radar, acoustics and both laser and millimeter wave detection. Targeting and maneuvering optics are used for long-range threat detection with obscuration grenades and vehicle countermaneuvers being used to avoid a threat. Short range search and track radar is used with explosive or fragmentation grenades selected and launched to intercept and defeat the threat. Acoustic threat detection increases robustness and extends the detection range to include small calibers threats. Detection of active targeting systems by laser and radar warning receivers provides cueing information for targeting optics and fire control systems.

  • Patent number: 7360478
    Abstract: A launcher which can be readily converted for use by either a right-handed or left-handed shot. The launcher has a receiver with upper and lower extensions extending forwardly from the receiver body. A barrel is pivotally mounted near forward portions of the extensions, in one of two positions, such that in one position it is pivotable from a home position aligned with the receiver and the extensions between the two extensions, to a load position with the breech of the barrel to the left, and such that in the other position it is pivotable from the home position, to a load position with the breech to the right. One way of accomplishing this is with a barrel support bracket to which the barrel is pivotally mounted, with the barrel support bracket being secured at or near the front of the receiver extensions, and being rotatable between two positions, each corresponding to a different swing direction for the barrel.
