Abstract: Proximity sensors, e.g., Bluetooth® sensors, are installed in a vehicle. Each sensor determines/estimates approximate distance from itself to a user mobile device. In response to the distance increasing above a predetermined distance departure limit, as the sensors communicate to a vehicle control system (VCS) through Bluetooth® or similar links, the VCS causes predetermined departure actions to be performed, such as locking the doors, turning off headlights, activating the vehicle's security system, and/or others. In response to the distance decreasing below a predetermined distance arrival limit, as the sensors communicate to the VCS through the link(s), the VCS causes predetermined arrival actions to be performed, such as unlocking the doors, flashing the headlights, beeping the horn, deactivating the security system, and/or others. Hysteresis may be applied to the decisions whether to perform the departure/arrival actions.

Abstract: A vehicle control system (VCS) in a passenger compartment interfaces with underhood components using a Bluetooth® link. The underhood components include a siren assembly with a sound generator and backup battery. The battery enables the siren assembly to function after the vehicle's battery is disabled. The siren assembly includes a Bluetooth® transceiver for establishing the link with the VCS. The siren assembly monitors the hood of the vehicle through a hood sensor, to detect unauthorized opening. In response to such opening, the siren assembly transmits an alarm to the VCS, which transmits an alarm to a user's mobile device and/or a security service. The sound generator may also be activated, by itself or under control of the VCS. The siren assembly connects to the engine computer/ignition module, to allow the VCS to monitor engine speed, and facilitate proper start of the engine when the VCS receives a remote start command.

Abstract: An over-bit backreamer. The backreamer is configured to be placed over a bit without detaching the hit from a drill string associated with a pilot bore. The backreamer has an internal surface that conforms to a steering surface of the hit. Rotation is transferred from the bit to the backreamer at the internal surface. The backreamer further defines a flange which interacts with a feature, such as a heel, on the bit. The flange and heel form a shoulder which transfers pullback force to the bit. The backreamer comprises a pullback eye that pulls a product pipe back through the borehole.

Abstract: A paintball loader for use on a paintball gun for feeding paintballs is provided. The paintball loader includes a container for holding a plurality of paintballs, a paintball agitator rotatably mounted in the container, the paintball agitator including at least two fins extending substantially perpendicular to the axis of rotation, the fins spaced apart from each other forming a gap therebetween large enough to accommodate more than one paintball. 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 compressed gas gun having a bolt and piston movable by the application of compressed gas, and a removable inline cylinder, are provided.

Abstract: A dermabrasion device includes an ergonomically contoured handle divided into at least two articulating sections separated by an annular cam ring, wherein each of the at least two articulating sections are coupled to one another and rotatable around a longitudinal axis of a longer one of the at least two articulating sections, whereby a distal end of the handle is displaced from the longitudinal axis. The device further includes an air pump disposed in at least one of the at least two articulating sections configured to draw air through the distal end of the handle, and a mount positioned at the distal end configured for mounting a dermabrasion tip around a channel leading to an inlet of the air pump.

Abstract: A compressed gas gun including a housing and a bolt movable within a passage in the housing. Movement of the bolt relative to the housing opens a flow path for firing a projectile.

Abstract: The disclosed apparatus, systems and methods relate to a bi-bell exercise device for low-impact exercises. The bi-bell can be used in place of a kettle bell, and has two handles and a selectively rotatable weight. The bi-bell can be used in a fixed configuration, where the weight does not move relative to the handles, or a rotating configuration, where the weight is free to rotate relative to a central post.

Abstract: A steerable rock bit attached by a drill string to a horizontal directional drill. The bit comprises a plurality of flanges radially extending from a central hub and a slanted face formed in the body of the bit. Cutting elements such as polycrystalline diamond compacts are disposed on the flanges on one side of the flanges such that they will provide cutting force when the bit is rotated in the direction of the cutting elements. The bit is advanced generally straight when the bit is rotated and is advanced at an angle away from the slanted face when the bit is not rotated.

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.
