  • Method and apparatus for determining wire resistance
    Patent number: 9429534
    Abstract: A method and apparatus qualifies a conductor for service and determines imbalance resistance of a conductor. The method and apparatus comprises feeding signals from a controller to termination ends of at least three wires of a conductor. In the controller a resistance difference is determined between first and second wires of the conductor using a measured resistance of one of the three conductor wires as a reference value. The conductor is qualified for services when the resistance difference between the first and second wires is below a threshold.
    Type: Grant

  • Method and apparatus for measuring AC shield continuity for shielded twisted pair structured datacomm cable link
    Patent number: 8570049
    Abstract: AC shield continuity for shielded twisted pair structured datacomm cable is determined by testing the cable, driven in a common mode, over a range of frequencies, to determine presence and location of shield breaks. DC ground path generated false results are thereby avoided.
