SYSTEM FOR COUNTERING AN UNMANNED AERIAL VEHICLE (UAV)
The present invention describes an air-burst projectile (130) and a system (200) for deploying the airburst projectile to counter an unmanned aerial vehicle (UAV) 10. Each airburst projectile includes one or more spinners (140, 140a-140d); each spinner has a sleeve or a tube (146), a number of radial partition plates (148, 148a-148d) extending from the sleeve/tube and an annular rear plate (144) connected to the sleeve. Adjacent partition plates thus form a compartment (150). Disposed in each compartment is a streamer or streamers (170,170a,170b), which are formed in a coiled-up state. When the airburst projectile is deployed into a flight path of a target UAV, the spinners (140, 140a-140d) are ejected and the streamers (170,170a,170b) are dispersed in the flight path to create a streamer cloud, so that a streamer may entangle with propellers of the UAV and bring down the UAV, or as a warning or fence marking shot.

Abstract
A wearable programming unit (WPU) (1 10, 1 10a- 1 10b) for assisting a user deploy air burst munition (ABM, 10) from a rifle (20) in an intuitive manner is described. The WPU has a ballistic processor (112), wireless communication channels (120), a vibrator (130), a display (130), a mode button (150) and up/down select buttons (160, 161). After an ABM is selected and loaded into the rifle, and a deployment distance entered in the WPU, the ballistic processor calculates and outputs a time of burst T and barrel angle alpha. The barrel angle alpha is received by a sighting unit (104) and appears as a target marker. Once the rifle is tilted and/or moved so that a centre of the sighting unit coincides with the target marker, the WPU vibrates as a signal to the user to trigger the rifle.

The present invention describes a casing ejection system (300) for a firearm that employs a bolt carrier assembly (100). The casing ejection system (300) includes an actuator rod (305) and an L -shaped deflector (350) to sweep a casing (12) laterally into an ejection chute (500). The actuator rod (305) is disposed substantially above the bolt carrier assembly (100).

The safety lockout circuit (290) ensures the firing circuit (280) is operative only after a predetermined delay time when an n-channel FET (292) is turned OFF. The micro-controller (220) also generates a TIME-OUT signal, which provides for self-destruction of a projectile that has failed to explode.

The present invention describes an improved cartridged projectile (100). The cartridged projectile (100) comprises a projectile (110) seating at a mouth of a cartridge case (130). The cartridge case (130) has a base (134) that houses a high pressure chamber (150). A side of the high pressure chamber (150) is capped by a pressure disc (170), which is secured onto the base of the cartridge case by a nozzle ring (160). The nozzle ring (160) has a tapered or conical surface that allows the pressure disc (170) to flex, and a surface (171) of the pressure disc (170) exterior of the high pressure chamber has intersecting V-shaped grooves (172). When propellant in the high pressure chamber (150) is burned efficiently, high pressure gases developing inside the high pressure chamber cause the pressure disc (170) to rupture at a predetermined pressure along the grooves (172) so that the gases propel the projectile (110) out of a barrel at a higher speed of about 100 m/s or more.
The present invention describes a projectile (100,100a,100b,100c,100d) containing two luminescent dye components (123,125) and a dye powder (126). The first luminescent dye component (123) is contained in an ampoule (122) whilst the second luminescent dye component is contained in a vial (124) disposed inside the ampoule (122). A front crusher (120,120a) is provided at a front of the ampoule to crush into the ampoule and vial, thereby allowing the dye components to react and give a luminous glow. Upon impact at a target, a nose cap (110) of the projectile (100,100a,100b,100c,100d) breaks and a rear crusher (130) behind the ampoule throws the ampoule (122) forward and sputters the luminous dye out of the nose cap (110); at the same time, the dye powder (126) surrounding the ampoule is sputtered out to mark the point of impact. In addition, a thermal glow is also provided to mark the point of impact. Projectiles also allow light tracing.

Abstract
The present invention describes methods for programming trigger time of a projectile (60) based on remaining flight time to a target (P) after the projectile (60) is airborne. The actual muzzle (Vo) and flight speeds (V1, V2, etc.) are independently determined and compared to those used by the ballistic computer (30), and a better estimate of trigger time is accordingly used to activate detonation of the projectile (60). In one embodiment, a Kalman algorithm is used to provide a better estimate of the projectile's flight speeds obtained by independent methods to provide the better estimate of the trigger time.
