Latest Patents

Holt's latest patents include the Dynamic Bendloss Measuring Device and the Turns Count Anomaly Detector. The Dynamic Bendloss Measuring Device allows for easy and repeatable determination of the bend sensitivity of single-mode optical fibers. It subjects the fiber to dynamically changing bend angles under varying degrees of tension and bend diameters. This device utilizes a swing arm capable of sweeping an arc that subtends a range of angles at any given bend diameter and fiber tension, calculating the bendloss from the light attenuation at each degree of the range. The varying bend diameters are provided by pins of diverse diameters that are inserted into an adjustably-sized aperture, while the variation in applied tension can be adjusted by changing the input current setting in the tension assembly.

The Turns Count Anomaly Detector is designed to detect irregularities in the pat count of a fiber optic cable from dispensers. It receives input from an infrared source and receiver that monitors a fiber optic cable during payout at speeds up to 700 feet per second. The detector comprises transistor-transistor logic one-shot configured as a negative recovery monostable multivibrator. The output from the one-shot indicates an anomaly in payout, which is marked for manual review or recorded for replaying at calibrated peel-off speeds.
