A ballistic trajectory method for a golf ball is disclosed wherein a ballistic trajectory of a golf ball having a plurality of dimples formed on the surface thereof when the golf ball is hit to fly at an arbitrary number of rotations and an arbitrary initial speed can be estimated and ballistic trajectory and flight characteristics of the golf ball can be evaluated without depending upon experimental evaluation which is based on an actual model thereby to allow a golf ball to be developed efficiently. The ballistic trajectory of the golf ball when the golf ball is hit to fly is estimated by successively calculating the flight distance and the height of the ball after every lapse of a very short period of time after the ball is hit to fly until it drops to the ground making use of arithmetic operation by a computer.

A sighting system for visually acquiring a target includes an optic device having a transmissive LCD array affixed thereon. The transmissive LCD array includes two or more LCD elements that are separately addressable to provide an aiming point. In embodiments, the sighting system receives information from an input system, such as ammunition information or environmental information, executes a ballistics program to determine ballistics information using the received information, and determines a range to the target. A controller calculates an aiming point using the ballistics information and the target range. The controller then addresses or energizes one of the LCD elements to provide the aiming point.

A mouse interface device and method for providing enhanced cursor control and indexing cursor control with force feedback. A force feedback interface device includes a manipulandum, such as a mouse, that is moveable in a local workspace. The device is coupled to a host computer that displays a cursor in a graphical environment, such as a GUI, on a display screen. A cursor position in the display frame is reported to the host computer derived from a reference position of the mouse in the local frame, and the host displays the cursor; for example, the cursor position may be scaled by a ballistics algorithm based on mouse velocity to allow fine positioning or coarse motion of the cursor. A force is output on the mouse based on interactions in the GUI, the force being determined based on mouse reference data or cursor ballistic data, depending on the type of force, to reduce distortion between visual and force outputs. Assistive forces can alternatively be output to achieve the enhanced cursor control. Indexing features allow control of the cursor when an offset between local and display frames exists, allow the user to reduce the offset, and reduce disconcerting collisions of the mouse with physical workspace limits.

A 2-D correction system uses intermittent deployment of aerodynamic surfaces to control a spin or fin stabilized projectile in flight; correcting both crossrange and downrange impact errors. Intermittent surface deployment develops rotational moments, which create body lift that nudge the projectile in two-dimensions to correct the projectile in its ballistic trajectory. In low spin rate projectiles (“fin stabilized”), the rotational moment directly produces the body lift that moves the projectile. In high spin rate projectiles (“spin stabilized”), the rotational moment creates a much larger orthogonal precession that in turn produces the body lift that moves the projectile. The aerodynamic surfaces are suitably deployed over multiple partial roll cycles at precise on (deployed) and off (stowed) positions in the cycle to nudge the projectile up or down range or left or right cross range until the desired ballistic trajectory is restored.

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 ballistic armored component attaches to the existing retention straps of common combat helmets and provides protection to the otherwise exposed lower skull and upper neck region. A fabric covering contains a soft armor or hard armor insert, and is mounted by straps or other fasteners to existing straps found in conventional helmets. The armored component adds additional protection from ground-level or subterranean munitions, by placing a ballistic shape on the lower skull region (occipital region), providing significant additional ballistic coverage with minimal weight and bulk. The fabric shell may also be connected directly to the helmet shell, to allow the component to withdraw within the helmet when the wearer's neck is flexed rearwardly.

A foamed composite armor laminate comprising interleaved combinations of ballistic resistant fabrics, and ceramic and/or metallic plates or sheets in a polymeric foam matrix. The foamed composite armor can be fabricated by inserting polymer powder or sheets between layers of fabric and/or ceramic or metallic sheets to form a laminated structure, heating this laminated structure under pressure to form a consolidated panel, and then foaming the polymeric portion of the consolidated panel in an autoclave or pressure vessel by saturating the polymeric portion with inert gas at elevated temperature, rapidly releasing the pressure and controllably cooling the laminated structure to ambient. Alternatively, pre-foamed panels can be laminated to fabric, ceramic and/or metallic sheets using adhesives or the like. Through proper selection of the various elements of the laminate, i.e. the foamed polymer matrix, the polymeric fabric(s) and the ceramic and metallic sheet(s), a wide variety of ballistic, flame retardance, stiffness and other properties can be custom designed into the product for specific end use applications.
