Abstract
A turns count anomaly detector for detecting any irregularities in the pat count of a fiber optic able from fiber optic dispensers. The detector receives an input from an infrared source and receiver that monitors a fiber optic cable during fiber optic cable payout at speeds up to 700 feet per second. A turns count pulse electronics circuitry supplies an input to a turns count anomaly detector. The turns count anomaly detector is comprised of transistor transistor logic one-shot configured as a negative recovery monostable multivibrator. Input to the one-shot is received from a pulse conditioning circuit comprised of a logic signal inverter and a digital flip-flop. The input to the pulse conditioning circuit is the output from the turns count pulse electronics. The output from the one-shot is a logic low which represents an anomaly in payout which is marked on a strip-chart recorder for manual review or recorded for replaying and stripping at 1/400 of real-time speed for calibrated peel off speeds up to about 700 feet per second for use of the turns count anomaly detector in a real-time mode.
