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.

2-D projectile trajectory correction system and method
ActiveUS7163176B1Accurate correctionAmmunition projectilesDirection controllersSystem usageBallistics
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.

Buffer for explosive device
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 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.
