A ball-throwing machine includes a camera connected to a computer vision unit and a microphone connected to a speech-processing unit. The computer vision unit processes images from the camera to determine a user's position, and to detect user gestures from a predetermined repertoire of gestures. The speech-processing unit recognizes user vocal commands from a predetermined repertoire of commands. A computer receives information from a control panel, from the computer vision unit, from the speech-processing unit, and from a file describing the ballistic properties of the ball to be thrown. The computer accordingly determines a ball trajectory according to the user's position and parameters indicated by a combination of control-panel settings, user gestures, and user vocal commands. The computer then adjusts the direction, elevation, ball speed, and ball spin to conform to the determined trajectory, and initiates throwing of a ball accordingly.

A tactical foregrip assembly for use with a firearm, the assembly having an independently rotatable grip mount assembly and an independently rotatable light mount assembly. The invention comprises a stationary mount assembly attachable to the receiver of a firearm, a grip mount assembly radially rotatable about and electrically coupled to the stationary mount assembly, and a light mount assembly radially rotatable about and electrically coupled to the stationary mount and engagable with said grip assembly. The present invention allows the operator to provide light to illuminate an area while simultaneously positioning himself in a manner so as to maximally use available cover.

A two-stage trigger assembly for the M16 or AR15 weapon systems. The trigger assembly comprises a spring loaded hammer, trigger and disconnector. Calibrated springs are provided to facilitate the adjustment of the second stage trigger pull weight. No set screws adjustments are necessary and a secondary safety sear similar to the factory original fire control components has been incorporated to prevent the unintentional mechanical discharge of the firearm. Installation of the disclosed device is identical to the factory fire control group and requires no hand fitting.

A firearm may have a plurality of power-consuming accessories that can be attached to the weapon. In order to reduce the weight of these power-consuming accessories, as well as the proliferation of their batteries, the Weapon Accessory Power Distribution System provides a common power source to power the power-consuming accessories attached to the weapon. One or more powered rails are provided on the handguard, which encircles the barrel of the weapon, to provide a point of mechanical and electrical interconnection for the power-consuming accessories to provide quick-connect mounting and dismounting of the power-consuming accessory, absent the use of connectors with their tethering cables, which are susceptible to entanglement. The Weapon Accessory Control System is provided to enable the user to control the activation of a power-consuming accessory as well as enable communications between the user and the accessory and among power-consuming accessories.

An electrical immobilization weapon having a prolonged range of effectiveness and improved accuracy compared to conventional Taser weapons, while being compact in structure and lightweight. The weapon having a replaceable cartridge which, when employed, can space a pair of electrodes to a specific critical area on a remote target, so the electrical energy carried by the electrodes can induce the involuntary contraction of the involved muscles through the critical area within a significant range of length between the electrodes for effective immobilization. The electrical energy generated by a power source of the weapon completes an electrical circuit through a minimum path being a length of at least 5 inches between the two points on the target.

Embodiments of the application can include an integrated rail system construction for a firearm with transverse ribs or tabs (e.g., picatinny rail) to include an undercut or slot at a front and / or rear face to cooperate with mounting structure for a detachable accessory. Embodiments of a rail structure can include a channel to pass wires used to power accessories mounted to the rail. Embodiments of the application can include methods for manufacturing an integral rail system.

A firearm including a bolt for securing a barrel such that the barrel attaches to a receiver with increased repeatability at the same location. The bolt included a tapered end and may also include a threaded section. The receiver comprises a barrel attachment feature which allows the bolt to pass through and can also include threads for engaging the bolt. The barrel comprises a beveled recess for engaging the tapered end of the bolt. The angle of the tapered end and the beveled recess are approximately reciprocal. The bolt passes through the receiver and its tapered end engages the beveled recess to secure the barrel to the receiver.

The present invention relates to compressed gas-operated firearms and more particularly to repeating gas cylinder pistols with conveyer feed of bullets for shooting. The pistol comprises a hollow pistol frame (1) made integral with a grip (3) and a trigger bow (50), a movable barrel (6) with a bullet bore (97), a load (12) and a mainspring (19) disposed on the barrel (6), a valve (57) installed in a gas chamber (110) inside a body (56), a gas cylinder (102) installed inside a rear hollow interior (104) of the grip (3), a magazine (27) installed in a front hollow interior (151) of the grip (3), separated from a rear hollow interior (104) by a partition (150), a striker-and-trigger mechanism installed inside the pistol frame (1) and on the trigger bow (50) and interacting with the movable barrel (6) and the magazine (27) for supplying bullets (246) and portions of gas from the gas cylinder (102) to the bullet bore (97) of the barrel (6), a mechanism for installing the gas cylinder (102), disposed below the gas cylinder (102) in the grip (3). In a hollow interior (4) of the pistol grip (1) a support (5) is installed, which serves as a base for the movable barrel (6) that moves along the support (5) under the action of the striker-and-trigger mechanism.

An inverted compound archery bow including an extended-capacity cam system having two cams, each cam engaging the bowstring and separate cables extending to limbs of the bow. The bowstring and cables are counter-wound on the cams, producing tension opposite and proportional to the inverse ratio of windings. Drawing the bowstring winds the cables onto the cams, producing limb tension that propels an arrow when the bowstring is released. An arrow rest located between full-draw and rest excursions of the bowstring accommodates the extended draw length of the bow. A bowstring arrestor engages the bowstring at an intermediate-draw position. A slide stabilizes and supports a rear portion of the bow, and a receptacle on the slide engages an adapter for a bowstring release mechanism.

A fire arm that includes a mounting rail having remotely powered electrical connectors with which modified prior art tactical accessories, such as tactical lights, night vision devices, laser sighting modules and the like can be interconnected. More particularly, the mounting rail of the invention includes electrical connectors that are operably interconnected with a relatively large, long life battery mounted in the stock of the firearm.
