A microprocessor circuit that is used to monitor and control a firearm. The microprocessor circuit accomplishes this by monitoring various sensor & control inputs, and acting on these inputs to execute user defined functions. The microprocessor circuit can use the sensory input to determine firearm statistics. These statistics can include the number of times the firearm has been shot, the efficiency of the firearm automatic action, range-to-target, and et cetera. The firearm system can also use a combination of sensors to fabricate a bullet chronograph whereby the muzzle velocity of a cartridge can be determined. These statistics can be date-stamped and recorded into memory. Statistics from Law Enforcement firearms can be used for courtroom evidence and police reporting. These statistics can also be used for firearm maintenance and warranty repair. The microprocessor circuit can display the statistical data to the user via simple light emitting diodes, or sophisticated liquid crystal displays. Data can also be downloaded to a computer docking station as well. The microprocessor circuit can also display the information within the optics of a riflescope. When used in conjunction with a laser range finder sensor, the microprocessor circuit can adjust the electronic cross-hairs (reticle) to compensate for the bullet trajectory.

A rapid feed paintball loader for use upon a conventional paintball gun. The rapid feed paintball loader includes a container for holding a plurality of paintballs. At a bottom portion of the container is a rotatable drive cone having a plurality of vertical fins. Each fin forms a gap with an adjacent fin large enough to accommodate a paintball. At the bottom of the container is an exit tube which exits from the bottom portion of the container and leads to an inlet tube of the paintball gun. A tube extension is mounted on an interior surface of the container adjacent to the sloped exit portion of the exit tube. The tube extension is mounted at a height which is above the top feed surface of the fins, and which is approximately equal to the radius of a paintball. A pivotable deflector is also mounted on an interior surface of the container adjacent the tube extension to prevent paintball jams from occurring within the interior of the container. The deflector is positioned above the top feed surface of the fins and below the height of the tube extension. The paintball loader also includes a microprocessor to variably control the rotational speed of the drive cone.

A rapid feed paintball loader for use upon a conventional paintball gun. The rapid feed paintball loader includes a container for holding a plurality of paintballs. At a bottom portion of the container is a rotatable drive cone having a plurality of vertical fins. Each fin spirals outwardly from a center axis of the drive cone. In addition, each fin forms a gap with an adjacent fin large enough to accommodate a paintball. At the bottom of the container is an exit tube which exits from the bottom portion of the container and leads to an inlet tube of the paintball gun. A portion of the exit tube is sloped at an angle equivalent to the slope of a top surface of the drive cone. A catch arm is mounted on an interior surface of the container adjacent to the sloped exit portion of the exit tube. The catch arm is mounted at a height which is above the top surface of the fins, and which is approximately equal to the radius of a paintball. During the operation of the paintball loader, a plurality of paintballs are placed in the interior space of the container. The paintballs fall into the gaps of the drive cone. The rotating drive cone pushes the paintballs toward the first opening. The catch arm then forces the paintball located in the gap into the exit tube for delivery to the paintball gun.

The bipod includes lockable controls for selectively limiting panning, tilting and canting in a manner which lets the shooter or user easily respond to changing situations when in the field.

The present invention is directed to a ball feed mechanism for use in a paintball loader. The ball feed mechanism includes a feeder which conveys or impels balls toward a feed neck, and a drive member which is concentric with the impeller. The feeder is coupled to the drive member through a spring. The spring is configured to store potential energy which is used to rotate the feeder and, thus, drive the balls toward the feed neck. An electric motor is used to rotate the drive member to wind the spring. The feed mechanism includes sensors which detect the motion of the feeder and the drive member. A controller determines the spring tension based on the relative motion of the feeder and drive member, and actuates a motor when necessary.

A gunshot detection system includes a firearm and a communication device. The firearm includes a transceiver circuit that detects the discharge of an ammunition round. Upon the discharge occurring, the transceiver circuit emits an electromagnetic signal. The electromagnetic signal is received by the communication device, which may be a cellular telephone or two-way radio. The communication device is equipped with a geographic location sensor, like a GPS receiver for example. Software within the communication device then causes an informational message that includes geographic information to be transmitted to a remote device. For instance, when a police officer discharges his firearm, an informational message stating “Officer 1234 has just fired 3 shots at the intersection of Cucumber and Vine—please respond” may be transmitted. The informational message may change as information like the geographic location change.

Adapter devices, apparatus, systems and methods of allowing a firearm to be supported by a foldable fore grip / gun handle. The fore grip gun handle can have bipod type legs that can be extendable from the handle. The fore grip handle can be just a vertical extension. The adapter can allow for the fore grip / gun handle to move from a fold back position along the bottom of the firearm so that the firearm can be easily carried, and the adapter to can allow for the handle to move down to a vertical support position beneath the firearm when the firearm is to be used. The adapter can also support a light in both a folded position and in a downwardly extended position, where light can be aimed forward, rearward to the side and / or pointed down from the firearm. The adapter can allow for a dual functioning component that can be either or both a fore grip and / or a light source. Other versions of the adapter can include a slidable thumb switch for locking a swinging plate with picatinny side rails to a main plate, and spring loaded detents for locking the swinging plate in substantially vertical orientations. Additionally, a folding rail system can be substituted for the existing picatinny rail system on firearms. The folding rail can have mounting holes for allowing the entire folding rail to be directly attached to the firearm, and have a hinge for allowing portions of the picatinny rails to pivot relative to the rest of the picatinny rails.
