  • Patent number: 6953225
    Abstract: A multi-element skateboard wheel having at least two different hardness surfaces including a softer center exterior surface and a harder side exterior surface. The softer center surface is the principal weight supporting surface which, because of its lower durometer material provides a quieter and smoother ride and better traction than conventional skateboard wheels. The harder side surface, which in the preferred embodiment is positioned on each side of the wheel, comprises a higher durometer material which exhibits less frictional resistance to sliding engagement with vertical surfaces such as curbs and with high inclines and the like. Moreover, in the preferred embodiment, the harder side surfaces extend around to the radial surface of the wheel at the precise same radial height as the softer center surface.

  • Patent number: 6931023
    Abstract: The present invention provides an access device which includes a timeslot allocation table having timeslot allocation information and a transmitter coupled to the timeslot allocation table. The transmitter transmits data and updated timeslot allocation information in accordance with the timeslot allocation information. The access device further includes at least one input channel where the transmitter allocates timeslot lengths for the at least one input channel according to the timeslot allocation information. The timeslot allocation table receives updated timeslot allocation information and the transmitter reallocates timeslot lengths according to the updated timeslot allocation information. The timeslot allocation table further includes timeslot allocation information for each of the at least one input channel.

  • Patent number: 6908359
    Abstract: A water skipping toy which has the desired characteristics of a few, simple, low cost parts that are easily produced using injection molding and minimal assembly time. The preferred embodiment comprises two substantially identical convex plastic discs each having an annular flange recessed from the outer perimeter of the disc. The flange of one of the discs is taller and has a slightly larger diameter than the flange of the other disc so that the two flanges are radially juxtaposed when the two discs are joined together. The discs may be secured together by the press fit engagement of the two annular flanges or the flanges may be glued to each other by a common adhesive along contiguous radial surfaces of the flanges. The discs create an air pocket between them which makes the toy lighter and buoyant. The third component of the preferred embodiment comprises a relatively soft rubber ring which encircles the outer radial edges of the discs to provide a safety barrier.

  • Patent number: 6895915
    Abstract: A method and apparatus for achieving reliability in starting V-Twin chain or belt-driven motorcycle engines using a conventional motorcycle battery and specially modified automotive cranking motor. The apparatus in its preferred embodiment utilizes a direct drive cranking motor configuration employing a cammed bearing clutch which is placed onto the engine's crankshaft along with a ring gear. The ring gear engages the geared shaft of the cranking motor directly, thereby bypassing the chain or belt-drive and thus effectively removing the main drive chain or belt from the cranking system. The gear ratio between the cranking motor and the ring gear may thus be selected to be optimum for the cranking motor so that the battery and cranking motor may be operated at near optimum power capabilities simultaneously.

  • Patent number: 6888623
    Abstract: The central system component of the present invention is a flexible “smart cable” which enables accurate measurement of local curvature and torsion along its length. These quantities are then used to infer the position and attitude of one end of the cable relative to the other. Sufficiently accurate measurements of the local curvature and torsion along the cable allow reconstruction of the entire cable shape, including the relative position and orientation of the end points. The smart cable for making these measurements comprises a multicore optical fiber, with individual fiber cores constructed to operate in the single mode regime, but positioned close enough to cause cross-talk (mode coupling) between cores over the length of the fiber. This cross-talk is very sensitive to the distribution of strains (curvature and torsion) along the cable.

  • Patent number: 6877434
    Abstract: Two distinct projectile stages are employed in a projectile configured to be fired at a remote target from a rifle, grenade launcher, gas gun or the like. A first stage comprises a pair of wire tethered contact darts for applying an immobilizing electrical discharge to the target. The second stage comprises a battery, circuits, transformer and wires used to generate a high voltage pulsed signal and apply it to the contact darts in the first stage. The higher mass of the second stage impacts the lower mass first stage at launch causing the first stage to be propelled to the target while the slower second stage hits the ground short of the target.

  • Patent number: 6874548
    Abstract: A vacuum packer for filling valve bags employs a load cell-based scale mechanism located within the vacuum chamber. An interior packer front plate is supported from the back, inner wall of the chamber on four flexure spring check straps. The front plate is supported from a single load cell mounted on the back, interior wall of the vacuum chamber. Side bag retention plates, end retention plates and the lower bag support saddle are mounted to the packer front plate. A flexible connection is furnished between the back of the filling spout and the interior back wall of the vacuum chamber. All other required piping is made directly to the back wall of the chamber, thus removing them from the scale mechanism entirely.

  • Patent number: 6851189
    Abstract: A clipless mechanism for a four-sided clipless bicycle pedal is made by a stamping and welding process. The stamping is preferably a progressive stamping process. The stamped parts include two components, an inner wing and an outer wing. The two stamped components are generally similar in shape to each other, but the inner wing fits within the outer wing. Each part is first stamped as a flat pattern by a progressive die. Each part then has radii stamped into the edges by the second station of the progressive die. Next, each part is partially folded by the third station of the progressive die. Then each part is folded completely by the fourth station of the progressive die. The actual number of steps may vary depending upon the material chosen, the thickness of the material and the design of the stamping tool. Then each part is welded closed and the resulting rectangular wings are assemblied in juxtaposed orthogonal relation to provide four shoe cleat engaging receptacles.

  • Patent number: 6818017
    Abstract: A high gain lens system for implant into the capsular bag after removal of the natural crystalline lens. A preferred embodiment of the invention comprises a combination of a positive or convex lens and a negative or concave lens. These two lenses are spaced from one another and their relative spacing and respective focal lengths determine their combined focal length. When the lens system is inserted into the capsular bag, two opposed haptic flanges on each side, extend toward the inner radial edge of the bag adjacent the ciliary muscles. When the muscles contract, the bag is stretched thereby compressing the haptic flanges together or at least toward one another. This action cause the two lenses to separate further from each other and the increased spacing between the positive and negative lenses shortens the focal length to permit focusing of objects at near distances. On the other hand, when the muscles relax, the bag relaxes also, the haptic flanges separate and the lenses come closer together.
