  • Hydraulic control valve brake system
    Patent number: 10814847
    Abstract: A hydraulic control valve for an ATV or motorcycle takes hydraulic input from a hand brake lever as an input to a first cavity of the control valve with a movable piston therein, and from a foot brake lever as an input to a second cavity of the control valve with a movable piston therein, with the two pistons being linked. A bypass channel extends around the piston in the first cavity, which is closed off when the first piston moves longitudinally.

  • Dynamic shape maintenance of aerospace subsystems using tuned mass dampers
    Patent number: 10801574
    Abstract: A vibration damping system employs a component having a directionally sensitive element thereon, mounted to an aircraft, which experiences dynamic excitation that induces bending deflection in the component that will reorient the directionally sensitive element. At least one tuned mass damper is mounted on the component in an orientation in which an internal mass of the tuned mass damper is moveable such that the tuned massed damper absorbs and attenuates at least a portion of the deflective motion, to thereby suppress bending deflection of the component in the particular axial direction and generally maintain the linearity of the directionally sensitive element.
