Abstract: A bicycle has an electric motor and attached single or multiple sprockets, gears, chains, belts, shafts and mounting brackets. Outer sprockets are independently turned by either the motor or the pedals, and these outer sprockets then turn an inner sprocket which drives the drive chain and turns the rear wheel. Either the motor or the pedals, or both, may propel the bicycle. The vehicle also includes a means for detecting gear shifting and thereupon reducing power to the motor for a short time interval.

Abstract: An electronic apparatus of the present invention has an electric fan in a casing. This electric fan generates air current between circuit substrates. The air current passes through the left-side gaps between the circuit substrates, and reaches the backside face of the electronic apparatus. The air current then passes through a power source substrate attached to a backside panel, and moves to the right. The air current then moves along the right-side inner surface and returns to the front side. The returned air is guided by a plurality of inner fins and then supplied to the electric fan. The heat generated in the casing is cooled by the air current circulating in the casing, and then conducted to the entire inner wall of the casing. The heat of the casing is then released into the atmospheric air through radiation fins arranged on the front face of the casing, the left and right side faces of the casing, and the front face of an open-close cover.

Abstract: A ride-ready bike carrier system has a support arm and handle assembly attached to a rear wheel holder via an extension arm, such that the handle assembly can engage a bike frame and wheel axle combination to further secure and stabilize a bike upon the system. The support arm and handle assembly, as well as the rear wheel holder, can be positioned such that the system can secure and stabilize bikes having wheels of differing size. Furthermore, since the handle assembly engages a portion of the bicycle which, for the most part, is consistent in size and design from one manufacturer to another, design incompatibilities are minimized.

Abstract: The improved watercraft comprises an underwater pod or pods, that support a pecentage of the displacement of the watercraft at rest. The percentage of displacement produced by the pods could vary widely based upon the purposes of the watercraft and its intended range of uses, i.e., speed, water conditions, cargo, length, etc. The improved watercraft is also comprised of one or more hulls at the surface, which when at rest, displace most of the remainder of the watercraft's total weight. The rest of the watercraft's displacement, normally a small percentage, is comprised of hydrofoils, or wings, and these provide lift for the watercraft when under way. These hydrofoils or wings would normally be designed to be sufficient in area and dynamic lift to raise the surface hull clear of the water's effects, if that was desirable for the intended purpose.
