  • Patent number: 6098198
    Abstract: A method and system for reducing drag on the movement of the human body through air or other fluid mediums and improving heat transfer including a placement of trip mechanisms at predisposed locations on the human body with the mechanisms constituting elongated protrusions adapted to intercept the laminar flow of fluid across the body and prematurely trip the laminar flow into turbulence whereby the downstream pressure on the body is increased allowing the body to move more freely through the fluid medium.
    Type: Grant
    Filed: November 16, 1998
    Date of Patent: August 8, 2000
    Inventors: David L. Jacobs, Eric L. Eagen, Jeffrey J. Rogers

  • Patent number: 4099769
    Abstract: An apparatus for adjusting tension in an elongated bicycle saddle. The apparatus includes a frame underlying the saddle and having one end in abutting contact with a flaired trailing portion of the saddle and the other end in proximity to a narrow leading portion of the saddle. An adjustment yoke is connected to the other end of the frame and provides a bearing seat for abutting reception of an adjustment member. A thrust bearing member extends through a downwardly contoured tip portion of the saddle and carries the adjustment member such that axial tension of the saddle may be facilely adjusted through the tip of the bicycle saddle.

  • Patent number: 4098537
    Abstract: A bicycle saddle including a narrow leading end portion, a central transition portion and a wider trailing end portion. A transverse rib extends across the saddle at the central transition portion and imparts flexural stiffness to the saddle. A longitudinal tension rib extends from the central transition portion to the wider trailing end and separates relatively thin and flexible pelvic zones fashioned within the wider trailing end portion.
