Abstract: An ammunition projectile has a plurality of distinctive marks arranged in at least one circular row around the projectile body, with the row of marks extending perpendicular to its longitudinal axis. The marks are illuminated by a strobe flash and successive images are captured by an electronic imager as the projectile exits the barrel of a weapon. A computer, coupled to the imager, processes the electron is signals to determine projectile yaw, spin and muzzle velocity.

Abstract: A system for precision aiming of a weapon that has a rail, aligned with a centerline of its barrel, with a bus for supplying power to, and providing communication between, a plurality of modular system components that are mounted and precisely aligned in an array on the rail. A core component receives data from the sensor components via the rail and produces an output for display of aiming data which allows an operator to precisely aim the weapon at a selected target.

Abstract: A practice ammunition projectile has a projectile head with one or more sheets of plastic material, each having a plurality of frangible “bubble shaped” compartments containing liquid chemical components for optical and/or Infrared marking of a target upon impact. The sheets are preferably flexible sheets in the nature of a “bubble wrap” of the type used as padding for packaging. These so-called “matrix packages” are installed adjacent the inner surface of the shell forming the projectile head and provide stability when the compartments break up upon setback when the projectile is fired from a weapon.

Abstract: A safety device for a front-loading weapon of the type comprising a mortar barrel having a closed breech end and an opposite open end for launching a mortar projectile. The device includes at least one sensor, configured for mounting adjacent the mortar barrel, for sensing a mortar projectile upon its insertion in the barrel and an electronic circuit, coupled to said sensor, for detecting movement of the mortar projectile past said sensor, thereby to detect the presence of the projectile in the barrel.

Abstract: A training ammunition projectile has a solid chemical component disposed in a base compartment that produces a gaseous visible plume after impact. The ammunition cartridge generates kinetic energy while propelling the projectile through a weapon barrel. This firing process imparts heat into a projectiles driving band. When the projectile is in flight, heat passes from the projectile's driving band into a compartment in the projectile housing the chemical component. When the component is exposed to increasing heat and low pressure, the it undergoes rapid sublimation. The projectile is configured with a vent opening in its base for emergence of the gaseous plume during flight. The opening is preferably capped to allow for stable storage and to prevent any gas from escaping until the projectile is fired.
