Abstract: A display center for a weapons control system consisting of a frame including front leg rails, rear leg rails, side rail supports, a top plate, a rear cross-bracket, a bottom plate, a monitor area and a removable electronics box. The display center may include an upper monitor, a lower monitor and a monitor support and an integrated keyboard and trackball.

Abstract: A pneumatic gun wherein a dual-action firing bolt moves forward, assisting in launching a projectile, under gas pressure. The bolt then releases the compressed gas to carry the projectile down the barrel. Return springs operate to move the bolt and its valves to a ready-to-fire position. Similarly, trigger actuation mechanisms are spring-actuated to return to the ready-to-fire position.

Abstract: A recumbent cycling apparatus is provided that includes a frame structure, wheels rotatably attached to supporting the frame structure, and a central frame element configured to absorb and reduce the forces transmitted through the frame structure to a user. The frame structure has a front frame section and a back frame section that are substantially parallel to the ground. The central frame element is a curved elongated member composed of chromoly steel that is attached to the front frame section and the back frame section and extends therebetween. The central frame element is configured to allow the front frame section and the back frame section to move substantially independently in response forces exerted on the wheels. The central frame element is disposed in a substantially vertical plane above the back frame section and the front frame section and is substantially perpendicular thereto. A pair of recumbent seats are mounted on the back frame section in a side-by-side relationship.
