  • Patent number: 8172966
    Abstract: Non-lethal payloads may be customized for particular uses and desired visual and audible incapacitation based upon the selection of igniter/activators and illuminants used with the non-lethal payloads. Non-lethal payloads employing high flame temperature igniter/activators and illuminants of powder metals, powdered metals combined with oxidizers, and powdered metals combined with heat-activated chromophores may produce improved “flashes” and “bangs” for non-lethal payloads used with diversionary or other devices. Such devices and methods of producing illuminance and noise are also disclosed.

  • Patent number: 8147135
    Abstract: Methods and systems are disclosed for determining an amount of bond between a structure and sensor. A method may include heating a sensor that is operably coupled to a measuring circuit and then measuring an output signal over time. The method may further include determining, from the output signal, a percentage of bond integrity remaining between the sensor and the structure. A system may include a measurement circuit having a sensor operably coupled to a sensing system. The sensing system may be configured for applying a thermal shock to the sensor and subsequently measuring an output signal of the measuring circuit. The sensing system may also be configured for determining, from the output signal, an amount of bond between the sensor and the structure.

  • Patent number: 8141473
    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.

  • Patent number: 8122808
    Abstract: A bullet feeding device having an expandable collet insertable into a die body. The die body is capable of receiving bullets from a source and directing the bullets to the expandable collet. The expandable collet restricts the passage of the bullet through the die body until the mouth of a cartridge case is inserted into the die body opposite the bullet. The mouth of the cartridge case causes the expandable collet to expand and allow the single bullet to pass through the expandable collet and be placed in the mouth of the cartridge case. As the completed cartridge is drawn from the die body, the expandable collet contracts above the tip of the bullet and prevents the passage of additional bullets until a new cartridge case is inserted. The expandable collet is capable of accepting bullets of different lengths and shapes. In addition, the expandable collet is easily interchangeable with expandable collets of other sizes to be compatible with bullets of different diameters.

  • Patent number: 8122833
    Abstract: A munition, such as a projectile formed of at least one reactive material, is provided. In one embodiment, the projectile includes a body portion formed of at least one reactive material composition wherein the at least one reactive material composition defines at least a portion of an exterior surface of the projectile. In other words, a portion of the reactive material may be left “unbuffered” or exposed to the barrel of a gun or weapon from which it is launched and similarly exposed to a target with which the projectile subsequently impacts. In one embodiment, the projectile may be formed with a jacket surrounding a portion of the reactive material to provide additional structural integrity. The projectile may be formed by casting or pressing the reactive material into a desired shape. In another embodiment of the invention, the reactive material may be extruded into a near-net shape and then machined into the desired shape.

  • Patent number: 8113118
    Abstract: A spin sensor includes a fuze housing, a sense weight and a rotating induction device. The rotating induction device comprises a first rotatable element affixed to the fuze housing and a second rotatable element affixed to the sense weight. The second rotatable element is mechanically coupled to the first rotatable element such that it may rotate relative to the first rotatable element. In addition, the second rotatable element is inductively coupled to the first rotatable element such that the relative rotation between the first rotatable element and the second rotatable element generates a spin signal on an electrical connection to the rotating induction device. The spin signal may be compared to a suitable spin profile to determine if a valid spin environment is present.
