Propellant in the hollow interior is ignited by the compressed priming composition.

Abstract: A paintball marker has an inline cylinder that includes a gas governor that reduces gas flow from a compressed gas source to a valve area when the bolt is in a firing position; this increases efficiency in the marker because only the required air is used to fire the paintball. This bolt operates independent of the valve pin, which increases cycle speed and enables the governor to open and close at an optimum time in the firing cycle. Further, when the bolt/piston is recocking, the gap between the valve pin and governor valve pin enables low pressure gas driving the piston to start pressurizing the cylinder and driving the piston rearwards without resistance from the high pressure gas. The marker also allows a user to remove the inline cylinder without the use of tools, and gives the user a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.

Abstract: A precision targeting system for a firearm has an image capturing scope, a processor, and an actuator. In one embodiment, a user indicates when he wants to lock onto the target, and then readjust his aim after receiving feedback from the system. In another embodiment, the system automatically locks onto the target. After lock on, the system compares successive images, and determines if the target has moved in the firearm sight. If movement has occurred, the system calculates the degree of the movement, and sends appropriate signals to an actuator which corrects the aim of the firearm. The system thereby converts reasonably good aim into precision aim.

Abstract: A closed loop current controller for an electromagnetic rail gun. It is necessary to control the muzzle velocity of a rail gun accurately for the gun to be a good artillery device. The present invention provides a closed loop control system to accurately regulate the energy transfer to a rail gun projectile and control its muzzle velocity. The rail gun control system includes a state space (state domain) control concept adapted to discrete control events that transition the system from one state to another until the final desired state (i.e., muzzle velocity) is reached. The control regulator preferably generates state transition functions that transition the projectile from state to state according to a defined current profile to provide a specified projectile muzzle velocity. The rail gun closed loop current controller also includes current reference compensation to correct for errors in previous state transitions.
