Abstract: A targeting system comprising a helmet, primary firearm, and secondary firearm. The helmet includes a helmet display. a primary firearm comprising: a receiver, a primary barrel, a primary camera, a swivel control, a first mounting point, a first display, and a second display. The secondary firearm includes a camera and a secondary barrel. The computing device comprises an user interface. The control circuit is coupled to the helmet, the firearm apparatus, and the user interface. The primary barrel is functionally coupled to the receiver. The helmet display is a heads-up display. The swivel control is functionally coupled to the secondary firearm. The secondary firearm is rotatably coupled to the first mounting point. The control circuit is configured to capture and convey images and video; receive a targeting instruction on the secondary firearm from the user interface; and instruct the swivel control to acquire a sight picture.

Abstract: A bicycle frame with an improved suspension system. The bicycle frame includes an adjustable dropout assembly that provides adequate shock absorption without affecting or being affected by the chain length or the pedaling action of the bicycle. The bicycle frame includes a uni-axis system that increases the efficiency and performance of the bicycle while eliminating latter movement found in traditional frames. The bicycle frame includes a micro-adjustable suspension system that allows the rider to easily adjust the suspension of the frame to precise measurements quickly and without additional tools.

Abstract: A door assembly for an equipment rack. A unitary frame includes an upper horizontal member, a left-hand vertical member, and a right-hand vertical member. A left-hand door is pivotally mounted on the left-hand vertical member for movement between an open position, in which equipment is accessible through a left-hand portion of the frame, and a closed position, in which access to equipment through the left-hand portion is blocked by the left-hand door. A right-hand door is pivotally mounted on the right-hand vertical member for movement between an open position, in which equipment is accessible through a right-hand portion of the frame, and a closed position, in which access to equipment through the right-hand portion is blocked by the right-hand door. A locking mechanism locks the left-hand door and the right-hand door in their respective closed positions, thereby blocking access to the equipment through the frame.

Abstract: A carrier for one or more water bottles attaches to the support rails of a bicycle saddle. A bracket, which can take several configurations, includes clamping structure at one end to attach to ends of the support rails and at the other ends has the structure to support one or more water bottles. The carrier positions the one or more water bottles rearwardly of the rider's buttocks and thighs so as to reduce aerodynamic drag while riding.

Abstract: Thumb twiddling devices that include a flat, hand-held housing (23) having a centrally located wheel (21) with an oblong thumb slot (35) and finger slots (33a, 33b) peripherally located about the wheel are disclosed. Thumb twiddling causes the rotation of the wheel (21) when a user's fingers (63) are interleaved together in the finger slots (33a, 33b) such that the thumbs lie in the thumb slot (35). In a toy form of the invention, thumb twiddle wheel rotations are sensed and the result used to control a display (49). In a controller form of the invention, sensed thumb twiddle wheel rotations are used to provide control signals suitable for controlling the movement of a video game object. Direction (e.g., steering) signals are provided by a tilt sensor mounted in the flat housing. Several thumb twiddle controllers can be used simultaneously by several video game "players" to control their respective objects in an interactive game.

Abstract: A multiple cylinder sinusoidal engine comprising a plurality of piston/cylinder arrangements lying parallel to, and around, a shaft cylinder is disclosed. Mounted in the shaft cylinder is a sine shaft, i.e., a cylindrical shaft having formed in its periphery at least one closed, double wave, continuous, sinusoidal groove. Coupling mechanisms couple the pistons to the sinusoidal groove or grooves of the sine shaft such that reciprocating motion of the pistons causes rotary motion of the shaft. Various air/fuel, exhaust and ignition passageways are provided through the sine shaft (or through the engine block in some embodiments) to allow air and fuel to enter the piston cylinders and exhaust gases to be emitted therefrom, and to allow ignition energy to be applied to air/fuel mixtures, as necessary. In one form, a single igniter is provided. The single igniter is coupled, sequentially, to each piston/cylinder arrangement as the sine shaft revolves.
