Abstract: A cable measuring device for measuring a cable of a predetermined LAN cable category wherein the cable has at least one twisted conductive pair and jacket covering the same includes a computer based device which removes tail up effect on the impedance/return loss measurement and which addresses the effects of jacket removed on the reflection test results of LAN cables.

Abstract: A lay meter includes a computer based device, a light source for creating a light plane operably connected with the computer based device, a shadow based sensor a light plane operably connected with the computer based device, and signal processing circuits and software for processing sensed signals such that a clean square wave voltage signal is generated in direct response to the lays passing through the light plane.

Abstract: A device for measuring the location of a conductor within an insulating sheath using three measuring planes, in which at least one measuring plane is able to locate the conductor and at least one is able to locate the periphery of the outer sheath.

Abstract: A capacitance monitoring system includes a capacitance gauge head for monitoring the capacitance between a measuring electrode and an electric cable travelling along a path parallel to the measuring electrode. The output from the capacitor gauge head is fed to a Fast Fourier Transform device (40) to produce, to indicate discrete cyclical faults in the cable and the frequencies to which they would be relevant. A cable speed detector (44) feeds a reference table device which stores different correction factors to correct the amplitude of the cyclical faults detected due to the attenuation imposed on the measured signal because of the specific length of the electrode. A multiplier (46) multiplies the cyclical fault signals detected by the relevant factors from the reference table device (42).

Abstract: An improvement in an on-line measurement system for product formed in a continuous manner includes a device for receiving a first waveform signal indicative of a presence of a first characteristic of the product and a second waveform signal indicative of a presence of a second characteristic of the product. A computer based device having phase shifting software is provided for shifting phase of each of the first waveform signal and the second waveform signal a predetermined amount to produce a respective first transformed waveform signal and a second transformed waveform signal.
