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 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.

A firearm grip with a rest is provided, which at least has a grip body with a hollow portion, a shell encasing and combined with an outside of the grip body and exposing a bottom of the grip body, and a rest received in the grip body and capable of being projected from the bottom of the grip body to position and support the firearm grip against a setting surface. The grip body and the rest can be coupled to each other by an elastic member that allows the rest to be resiliently retracted back into the grip body. Alternatively, the rest can be pivotally coupled to the grip body and rotatably retracted into the grip body. The above firearm grip eliminates the shortcomings of the prior art.

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.
