At least two paintballs are positioned in the gap between the fins. A motor is configured to rotate the paintball agitator. The container includes an exit tube exiting from the bottom portion of the container and leading to an inlet tube of the paintball gun. A microprocessor in communication with a sensor may also be provided for controlling the motor. A deflector for deflecting paintballs may also be provided, the deflector movably attached to the interior surface of the container.

Abstract: The present invention is directed to a ball feed mechanism and associated method 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 feeder. The feeder is coupled to the drive member. An electric motor is used to rotate the drive member which in turn causes the feeder to rotate. The feed mechanism includes sensors which detect the motion of the feeder and the drive member. A controller determines the position of the feeder relative to the drive member and actuates a motor when necessary.

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 tools, and provides a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.

Abstract: A paintball loader is provided having a body split vertically along a length of the body into two side portions, wherein the side portions are attached by a hinge along an upper portion of the paintball loader body.

Abstract: A compressed gas gun is provided, wherein the body houses a firing assembly and an internal, built-in projectile feed mechanism. The projectile feed mechanism is preferably formed as a rear or butt stock of the compressed gas gun. The projectile feed mechanism preferably feeds projectiles to the firing assembly via a feed ramp having an S-shaped transition portion. The compressed gas gun preferably includes a removable top feed rail assembly that can be removed to expose the interior of the compressed gas gun body for field stripping. Central control circuitry is preferably provided for controlling both the firing assembly and the projectile feed mechanism.

Abstract: A paintball gun generally comprising a body split into an upper portion and a lower portion is provided. The split body allows exposure of internal components for access, service and/or maintenance. In an embodiment, the paintball gun preferably includes a valve assembly fixedly secured within the body. In an embodiment, the paintball gun preferably includes a barrel adapter for engaging a barrel, with the barrel adapter secured within the body by a gripping piece. A method of servicing a paintball gun is also provided.

Abstract: In some embodiments, a sensor system may include a deformable structure and a sensing element. The deformable structure may include at least one layer of piezoelectric material and at least one actuator port disposed on the at least one layer of piezoelectric material. The deformable structure may deform in response to external phenomenon. The at least one actuator port may be configured to actuate the at least one layer of piezoelectric material via application of an electrical signal to the at least one layer of piezoelectric material. The at least one layer of piezoelectric material may be configured to apply a force to the deformable structure when actuated. The sensing element may be configured to sense deformation of the deformable structure capacitively, optically, or via a sensing port according to embodiments.

Abstract: The present disclosure is directed to a propeller driven remote control flying device having an enclosed body. The motor and propellers of the device can be contained within the enclosed body. The enclosed body can include a plurality of pores through which air passes, with one side of the body generally functioning as an air intake, and the opposite side of the body functioning as an air outlet. The pores can be sufficiently small so as to prevent contact between persons, animals or articles and the motor driven propellers.

Abstract: A method of fatiguing a target muscle group of a user using an exercise device includes grasping in each hand one of a pair of outer handles of an exercise device, positioning the user's feet to be substantially aligned with the user's shoulders while maintaining the user's torso in a substantially upright orientation, positioning each hand in an initial position relative to the user's torso, cyclically pulling the outer handles away from one another in a cyclic motion to apply a cyclic pulling force to the tethers to cause the central disk to alternately rotate in opposing directions of rotation, and moving one or both hands to a secondary position relative to the user's torso and repeating the application of the cyclic force to fatigue the initial target muscle group or to fatigue a secondary target muscle group.

Abstract: A spring-loaded feed mechanism for a paintball loader. The feed mechanism includes an inner spool and an outer spool. A torsion spring is positioned between the inner and outer spools. The outer spool includes a pressure wall, from which the torsion spring is located on one end of the spring. A retaining wall is attached to the inner spool and is located at the opposite end of the torsion spring. When an operator of a paintball gun using the spring-loaded feed mechanism discontinues firing paintballs, the feed mechanism is stopped. Simultaneously, during the deceleration of the feed mechanism, the torsion spring is compressed, which allows the mechanical energy of the rotating feed mechanism to be stored within the compressed spring. When the operator desires to fire the paintball gun, the feed mechanism is accelerated to the requisite rotational speed. The compressed spring is release, thereby allowing the spring to assist in accelerating the feed mechanism to the necessary rotational speed.
