The present invention provides a projectile device and a method of manufacture of a projectile device and in particular, to a pistol bullet and a rifle bullet and method of manufacture of same. In one embodiment, the projectile apparatus has a cylindrical body portion having a diameter, a front nose section tapering from a most proximal point of the projectile to the cylindrical body portion, and a rear tail section connected to the body portion and extending to the most distal point of the projectile, in which the front nose portion comprises a plurality of twisting depressions forming troughs.

Method and apparatus on charges injection using piezo-ballistic-charges injection mechanism are provided for nonvolatile memory device. The device has a strain source, an injection filter, a tunneling gate, a ballistic gate, a charge storage region, a source, and a drain with a channel defined between the source and drain. The strain source permits piezo-effect in ballistic charges transport to enable the piezo-ballistic-charges injection mechanism. The injection filter permits transporting of charge carriers of one polarity type from the tunneling gate through the blocking material and the ballistic gate to the charge storage region while blocking the transport of charge carriers of an opposite polarity from the ballistic gate to the tunneling gate. The present invention further provides an energy band engineering method permitting the memory device be operated without suffering from disturbs, from dielectric breakdown, from impact ionization, and from undesirable RC effects.

A device can be supported on a weapon, and has a range portion that specifies a range to a target, a sensor portion that provides sensor information representing an orientation of the device; and a sight that facilitates weapon orientation in preparation to fire the munition. The device has an electronic control portion responsive to sensor information from the sensor portion and a range from the range portion for calculating how to hit a target with a munition, and for causing the sight to present a visual indication of how to orient the weapon so that the munition will hit the target, the electronic control portion terminating the presentation of the visual indication by the sight in response to a lack of user activity for a selected time interval during the presentation of the visual indication.

A device has structure that can support the device on a weapon, and a range portion that specifies a range to a target. A sensor portion provides sensor information representing an orientation of the device, and an electronic control portion is responsive to sensor information from the sensor portion and a range from the range portion for calculating how to hit the target with each of first and second munitions that are different.

This invention relates to armored protective helmets offering the wearer ballistic protection, and specifically to helmets offering lightweight ballistic protection from rifle ball ammunition. Potential applications include use by law enforcement personnel and combat soldiers.

A ballistic effect compensating reticle (e.g., 200 or 300) and aim compensation method for rifle sights or projectile weapon aiming systems includes a multiple point elevation and windage aim point field (e.g., 150 or 350) including a primary aiming mark (e.g., 158 or 358) indicating a primary aiming point adapted to be sighted-in at a first selected range and a plurality of secondary aiming points arrayed beneath the primary aiming mark. The method for compensating for a projectile's ballistic behavior while developing a field expedient firing solution permits the shooter to express the field expedient firing solution in units of distance, (e.g., yards or meters, when describing or estimating range and nominal air density ballistic characteristics), and velocity (e.g., mph or kph, for windage hold points).

A non-fibrous ultra high molecular weight polyethylene tape having a width of 1-inch or greater and a modulus of 1,400 grams per denier or greater. The non-fibrous UHMWPE tape is obtained by compression molding ultrahigh molecular weight polyethylene powder at a temperature below its melting point and then drawing and stretching the entire resultant compression molded UHMWPE sheet, with no slitting or splitting of the sheet, at a draw ratio of at least 100:1. The UHMWPE tape can be produced in weights of 6,000 to 90,000 denier or greater. The UHMWPE tape of the present invention minimizes the effect of stress concentrators that are prevalent with fibers and thereby enables the tape to be drawn at much higher draw ratios than is possible with fibrous UHMWPE. When used in ballistics panels, the high modulus high molecular weight polyethylene tape of the present invention improves ballistic performance by providing enhanced dissipation of the impact energy of a projectile.

A buffering device for use in conjunction with a downhole tool string, wherein the tool string includes a ballistics device. The buffering device includes a mandrel attached within a tool string and proximate to the ballistics device. An anchor is disposed on the mandrel and a disk plate is coaxially placed on the mandrel that is slideable thereon. The disk plate is proximate to the ballistic device. A resilient member, such as a spring, is coaxially placed on the mandrel between the disk plate and the anchor. The pressure wave produced by activation of the ballistic device pushes the disk plate toward the anchor and compresses the spring there between. Since the disk plate extends outward into sealing contact with casing lining the wellbore, compression of the spring dissipates energy waves produced by activation of the ballistic device.

A rear break away ballistics vest (1) having a front section (36) and a back section (11) that are securable to one another. The front section (36) has a first side front section (16), a second side front section (17) and an upper front section (18). The back section (11) has a first side back section (13), a second side back section (14) and a back section cover (12) secured to the back section (11). A release strap (44) is located on the front section (36) to permit a user to quickly and easily remove the rear break away ballistics vest (1) with one hand. A first shoulder strap (4) and a second shoulder strap (5) are connected to the front section (36) and extend to the back section (11). A first clip (38) is located on the back section (11) to release the first shoulder strap (4) from the first clip (38). Similarly, a second clip (39) is located on the back section (11) to release the second shoulder strap (5) from the second clip (39).

The invention discloses a missile-borne deep integrated ARCKF (Adaptive Robust Capacity Kalman Filtering) method under a strong maneuvering condition. The missile-borne deep integrated ARCKF method comprises the following steps: generating a ballistic trajectory and corresponding IMU (Inertial Measurement Unit) data of a simulated strong maneuvering missile through a trajectory generator; inputting the generated ballistic trajectory into a satellite signal simulator, and generating a GNSS (Global Navigation Satellite System) intermediate-frequency signal; then inputting the generated GNSS intermediate-frequency signal into a software receiver and carrying out inertial navigation calculation on the IMU data; establishing a state equation and an observation equation of a GNNS / SINS (Strapdown Inertial Navigation System) deep integrated navigation system under a launch inertial coordinate system; simultaneously integrating a robust M-estimation algorithm in a robust estimation theory and adaptive factors to a CFK (Capacity Kalman Filtering) algorithm, forming an ARCKF algorithm, and carrying out filtering correction on a system state. The missile-borne deep integrated ARCKF method disclosed by the invention can be used for GNSS / SINS deep integrated navigation of a carrier under strong maneuvering and high dynamic conditions, and the anti-jamming capability of navigation and the navigation accuracy are effectively increased.
