A method and system for increasing dampening capacity utilizing dry friction between individual wires of a rope embedded in a molded component formed from a composite. The individual wires allow inter-wire friction to occur during part vibration. The amount of inter-wire friction is controlled by the pressure when the component is molded. The component includes a body that is a molded matrix formed form a composite material. The body may be of any material selected from the group consisting of a polymer, a metal or a ceramic material. One or more vibration-dampening ropes are embedded in the body. The vibration-dampening ropes may be elongated segments or may be a rope having connected ends that form one or more rings. The vibration-dampening rope includes at least outer wires and can further include a plurality of inner wires surrounded by the outer wires. Composite material is prevented from passing through the outer wires, thereby forming voids between the wires.

The present invention pertains to an auto tensioner (1) to be provided in an auxiliary-driving belt system, including a friction member (6) that is sandwiched between an arm (3) and an inner circumferential surface of an outer cylindrical portion (21) of a base (2) in the radial direction of the outer cylindrical portion (21) and that has an arc-shaped surface (60) locked to the arm (2) and slidable with respect to the inner circumferential surface of the outer cylindrical portion (21), in which the friction member (6) is provided so that the arc-shaped surface (60) remains at a height equal to or higher than a horizontal plane (HP) passing through a central axis (R) when sliding with respect to the inner circumferential surface of the outer cylindrical portion (21) as the arm (3) oscillates.

An electric adjustable magnetic control damper comprises a force applied unit, a magnetic control unit, a driving unit, and a control unit; a driving rod drives the force applied unit displaced linearly, and a screw sleeve for the screw sleeve to displace linearly and for the screw rod and the magnetic ring to be rotatable, the magnetic control unit has a fixing seat able to displace linearly, and the fixing seat has a the permanent magnet, the driving unit has a motor and a gear train, the control unit can input the required damper value to drives the motor to rotate; whereby the motor and the gear train drives the fixing seat displaced, and create a required gap between the permanent magnet of the fixing seat and the rotor of the magnetic ring to create eddy load for being dampers of axial displacement of the driving rod and rotation of the rotor, and the damper achieves the effect of fitness exercise.

An artificial joint with a knee axis including a swing-phase control means having a variable friction-based swing-phase controller. The variable friction-based swing-phase controller may apply different resistances at different ranges of motion by altering the torque applied upon the knee axis by altering any combination, or all of the following: the length of a lever arm and a force applied. This may be done to optimize the swing-phase control of the artificial joint to promote natural and smooth walking gait.
