  • Patent number: 7059251
    Abstract: A propelling charge support comprises horseshoe-shaped clips for engaging the tail fin and holding the propelling charges together for protection, a rounded saddle for holding the propelling charges of the cartridge, and winged edges to protect the propelling charges and aid in removal of the propelling charge support from the tail fin. The propelling charge support further comprises a flat outer surface on which the propelling charge support loaded with propelling charges can rest while being installed onto the tail fin. It comprises a fin engagement clip that interfaces with a fin blade when installed on the cartridge, and that prevents rotation of the propelling charge support and propelling charges about the tail fin axis during rough handling and transportation, preventing damage to the propelling charges.

  • Patent number: 7052562
    Abstract: High explosives suitable for filling very small volume loading holes in micro-electric initiators for micro-electro-mechanical mechanisms, used as safe and arm devices, are prepared from slurries of crystalline energetic materials and applied using various methods. These methods include swipe loading, pressure loading and syringe loading. A volatile mobile phase may be added to the slurry so as to partially dissolve the energetic material so that, upon evaporation of the mobile phase, the energetic material precipitates and adheres to the loading hole.

  • Patent number: 7005981
    Abstract: A method and apparatus for the generic extraction and compression of surveillance information that facilitates high performance data fusion in distributed sensor systems. According to the method, multiple sensors (120[1] . . . 120[N]), distributed over a wide surveillance area (100), sense surveillance data of interest (310), optionally filter that sensed data (340), extract non-essential data (360) from the filtered data, compress in a manner specific to the extracted data (370) the extracted data for transmission and subsequently transmit (380) the compressed data to a “master” processing system (220) for integration/fusion with other transmitted compressed data streams originating from other sensors. Reductions in required data transmitted is on the order of 100:1.

  • Patent number: 6967614
    Abstract: A projectile launch detection system utilizes a continuous wave radio frequency signal (CW/RF) to confirm muzzle exit. The projectile launch detection system can be used in smoothbore, fin-stabilized, non-air breathing projectiles. The gun tube appears as a waveguide to the projectile launch detection system during projectile launch. The projectile launch detection system transmits a CW/RF signal down the gun tube during launch of the projectile. A portion of the CW/RF signal is reflected back by an impedance mismatch at the boundary between the muzzle of the gun tube and free space. Upon exit by the projectile from the gun tube, an exit signature is detected that is defined by the impedance of the gun tube and by a ratio of the diameter of the gun tube to the frequency of the CW/RF signal. The projectile launch detection system processes the exit signature to detect a muzzle launch of the projectile from a specific gun tube.

  • Patent number: 6829857
    Abstract: A bipod has a base attached to the weapon and a pair of legs which extend in a use position from the base downwards and outwards. Each leg includes an inner member having a pointed distal end and a proximal end attached to the base, and an outer member which freely slides relative to the inner member. The outer member includes a foot through which the pointed distal end extends when the outer member is in an retracted position and hence the pointed distal end is in an exposed position. Each leg also includes a holding mechanism which holds the outer member relative to the inner member such that the pointed distal end is located within the outer member adjacent the aperture of the foot when the outer member is in an extended position and hence the pointed distal end is in a withdrawn or protected position.

  • Patent number: 6724341
    Abstract: An autonomous onboard absolute position and orientation referencing system provides a means of efficaciously and economically embedding guidance and control components into the fins of supersonic, highly maneuverable small, medium-caliber and long range munitions. Embedded resonant cavities form an integral part of the referencing system. The magnitude and phase information received by the integral antennas is used to determine the munition orientation. Embedded sensors provide continuous, onboard information about the angular orientation of the munition, such as its pitch, yaw, and roll angles, as well as its absolute position relative to a ground station.
