Abstract: A safety and arming unit for a fuze of a projectile has a rotor for interruption of a firing chain. The rotor can rotate from a safe position to an armed position. In order to allow the safety and arming unit to be designed to be physically compact and such that it can be assembled easily, it is proposed that it has a first and a second rotor safety device which each engage in the rotor in order to block rotor rotation to the armed position, wherein the first rotor safety device is designed to carry out a release movement by virtue of its inertia during a launch acceleration of the projectile, and the second rotor safety device has a pyrotechnic charge for producing a release movement.

Abstract: A selective fragmentation pattern of explosive material is applied to a surface of a munition. None, some, or all of the explosive material in the selective fragmentation pattern may be detonated, selectively stamping the surface of the munition with the detonated explosive material. The portion of the selective fragmentation pattern selected for ignition is determined by lethality requirements of a target of the munition. Upon detonation of the munition, fragments are formed based on the selected portion of the selective fragmentation pattern. Consequently, igniting all, some, or none of the selective fragmentation pattern may vary lethality of a munition and one munition may be used for a wide range of lethality.

Abstract: A cartridge box of a pneumatic toy gun includes an air lock system and a struck element disposed on the upper inside the case of the cartridge box, and further includes a control system having a pushing rod and a resisting rod, wherein a front end of the pushing rod extends into the bullet-out passage disposed inside the case. When there is no bullet in the bullet-out passage, a lateral end of the stripping rod resists upward against the front end of the pushing rod to make the back end of the resisting rod moving downward to resist against the resisting portion of the struck element, resulting that the struck element cannot push the air lock system forward. Thereby, when there is no bullet in the cartridge box, even if the trigger is pressed, the air lock system cannot moves to push the bolt. Hence, firing without bullet will be avoided and the effects of the simulate gun would be achieved.

Abstract: A firearm attachable bullet trap for use on a gas operated firearm having a compensator attached to the barrel. The bullet trap captures bullets from live rounds and provides an visual and tactile indication of live rounds having been fired. The bullet trap is designed for the shooting of blank rounds, but is adapted to handle live rounds having a bullet in a semi-automatic or automatic firearm.

Abstract: A SAFE and ARM mechanism is includes an elongated casing having a first end and a second end. A high-G force firing pin is arranged relatively near to the first end and a low-G force firing pin is arranged relatively near to the second end. A detonator is arranged between the high-G force firing pin and the first end. When a G-force within a first range of magnitudes is applied to the casing along its longitudinal axis, the low-G force firing pin is displaced to strike a portion of the high-G force firing pin, and if a G-force within a second range of magnitudes is applied to the casing along its longitudinal axis, the high-G force firing pin is displaced to strike the detonator. The device may become ARMED in response to a centrifugal force generated by spinning the casing on its longitudinal axis.

The vehicle may include a body comprised of sheet materials, the body having a longitudinal centerline, an upper portion including opposite side portions, a first bottom portion defining a V, with the apex of the V substantially parallel to the longitudinal centerline of the vehicle and extending along a portion of the vehicle, and a second bottom portion defining a V, with the apex of the V substantially parallel to the longitudinal centerline of the vehicle and extending along another portion of the vehicle. The first bottom portion further includes an energy-absorbing member extending longitudinally within an interior of the first bottom portion. The energy-absorbing member may be on the inside of the apex of the V and be held in position during the blast by its own inertia.

The sleeve has a free end portion radially to adjacent to and coupled to the second end portion of the body. The sleeve and the body defines an interior area configured to contain a combustible propellant. A non-combustible base at least partially is coupled to the sleeve and is adjacent to the second end portion of the body.

Abstract: A protection system (10) is proposed which comprises a storage container (1), a transport unit (2), an activation unit (3), an ejection unit (4), a monitoring/control unit (5) and a user unit/interface (6), as well as at least one effect body (7). This system (10) is integrated at the front in a flying carrier (11), and a modular system (10), with the object of positioning spoof measures in a defined manner, in this case by means of the effect body (7). The various effect bodies (7) are preferably activated and initiated in a controlled manner without any physical contact, in the same way as pneumatic or mechanical ejection of these effect bodies (7). The effect bodies (7) are packets without any munitions, and are responsible for the actual effect of the system (10) outside the carrier (11).

Abstract: In methods and apparatuses, a weapon includes a trigger module for sensing trigger input from a shooter and generating a trigger signal, and a firing module for controlling firing of a projectile responsive to a fire control signal. The weapon also includes an image sensor configured for mounting on the weapon and sensing a series of images over a time period of interest while the trigger signal is in a motion-estimation state. A controller is configured for determining when to fire the weapon by receiving the images from the image sensor and generating a motion estimation history over the time period of interest responsive to changes in the images. The controller is also configured for determining a centroid of the motion estimation history and asserting the fire control signal when the trigger signal is in a fire-enable state and a current image is within an offset threshold from the centroid.

Abstract: There is shown in this invention a face cheek rest for a firearm that cushions a shooter (to generally aim then shoot) against uncomfortable interaction with harsh surfaces on a firearm buttstock or body.

Abstract: In accordance with the present invention, there is provided a deployment device that is operative to deploy Special Material (SM) to protect the vehicle when an enemy infrared (IR) threat is present. The deployment device constructed in accordance with the present invention comprises at least one, and preferably a pair of canisters which are each filled or loaded with SM, then factory sealed to prevent oxidation or contamination. Each of the canisters included in the deployment device includes an input shaft which, when rotated, is operative to transmit the rotary motion to each of four threaded rods. The rods have two primary functions, which are to advance a piston thereby preloading the SM within the canister toward the open end thereof, and to turn rotary metering devices which are located at the open end of the canister. The advancing piston maintains consistent compression in the SM stack within the canister.
