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: 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.

Abstract: A fiber optic flaw detection system and method for detecting flaws in an optical fiber and for identifying the type of flaw as a lump, neckdown or other is provided. Three collimated beams of light rays illuminate the optical fiber substantially orthogonal to a longitudinal axis thereof. Each beam is scattered by a flaw-free optical fiber into an in-plane scattered light segment which is scattered in a radial plane substantially perpendicular to the longitudinal axis of the optical fiber. A flaw in the optical fiber scatters the light rays into an out-of-plane scattered light segment which is outside of the radial plane. A pair of photocells detects the out-of-plane scattered light segment for each of the beams. One photocell detects the portion of the out-of-plane light segment scattered opposite the direction of travel of the optical fiber. The other photocell detects the portion of the out-of-plane scattered light segment scattered toward the direction of travel of the optical fiber.

Abstract: A system for detecting flaws in an optical fiber includes a light source which generates a beam of collimated light rays to illuminate the optical fiber substantially orthogonal to a longitudinal axis thereof. The beam is scattered by a flaw-free optical fiber into an in-plane scattered segment which is scattered in a radial plane substantially perpendicular to the longitudinal axis of the optical fiber. A flaw in the optical fiber scatters the light rays into an out-of-plane scattered segment which are scattered outside of the radial plane. A light attenuator removes the in-plane scattered segment of the beam and a light detector detects the remaining out-of-plane scattered segment. An electrical circuit monitors the light detected by the light detector and determines whether a flaw is present in the optical fiber. To compensate for fluctuations in the power output of the light source, a linear light detector replaces the light attenuator to detect the in-plane scattered segment of the beam.

Abstract: A miniaturized laser scanning micrometer for making precision hand-held measurements comprises a compact housing for enclosing the micrometer and defining a main body handle portion which is gripped to hold the micrometer and a scanning gap extension projecting from the main body to define a scanning gap at a distance spaced from the main body. A laser diode and collimating lens housed within the main body generate a collimated laser beam and a photocell housed within the main body detect the collimated laser beam after it has been scanned through the scanning gap. A motor driven scanner mirror receives the collimated laser beam and repeatedly scans it upon a folding mirror which directs the laser beam toward the distal end of the scanning gap extension along one side thereof.
