  • Patent number: 10752322
    Abstract: Method and apparatus for an improved recreational canopy which may be used with watercraft wherein the canopy is constructed by using a pair of flexible, resilient rod-like members wherein one end of each of the flexible rods is inserted through mating apertures in an upright support member mounted onto the watercraft, or other structure, so that the rods are bowed outwardly and frictionally held in the stanchion. A canopy, which may incorporate solar cell fabric, is attached between the rods so that the canopy generally appears to be in an elongated V-shaped structure which stretches across a portion of the supporting structure, such as a watercraft, between the flexible rods. The upper end of the upright support member may be pivotable and the rod-like members may be disposed in a cap removably disposed on the upper end of the upright support member. A lighting system including an alternative power source being provided on the canopy.

  • Patent number: 9726268
    Abstract: A robust ground traction (drive) assembly for remotely controlled vehicles, which not only operates smoothly on surfaces that are flat, but also upon surfaces that include rugged terrain, snow, mud, and sand, is provided. The assembly includes a sun gear and a braking gear. The sun gear is configured to cause rotational force to be applied to second planetary gears through a coupling of first planetary gears. The braking gear is configured to cause the assembly (or the second planetary gears) to rotate around the braking gear when an obstacle or braking force is applied.
