  • Creep testing fixture and method
    Patent number: 6647802
    Abstract: A creep testing fixture and method for applying a precise amount of constant tensile stress to a creep test specimen to allow for precise measurement of creep in the test specimen. The fixture includes first and second mounting grips for holding opposite ends of a test specimen. A frame supports the mounting grips for relative reciprocal movement toward and away from each other. A tensile spring is connected between the first and second mounting grips. The frame subjects a test specimen held between the mounting grips to tensile stress in response to axially inward force that the tensile spring applies to the frame.
    Type: Grant
    Filed: March 29, 2001
    Date of Patent: November 18, 2003
    Assignee: Automotive Composites Consortium

  • Vertical jump measuring device
    Patent number: 6181647
    Abstract: A method to measure height of a vertical jump of a jumper. At least one switch is deactivated by the jumper stepping thereon. The switch is initially activated by the jumper jumping upward therefrom and thereafter deactivated upon return. A time period is measured while the switch is activated. The square of the activated time period is calculated and thereafter the result is multiplied by a constant to derive vertical jump height. Finally, the resultant vertical jump height of the jump is displayed.
