Latest Patents
One of his latest patents is the Strand Shield Defect Detector. This invention provides a method and apparatus for detecting imperfections in a semi-conductive strand shield applied to an electrical conductor. The method involves applying AC current between a bare portion of the conductor and an apparatus that applies a jacket of insulating material over the strand shield. As the conductor and shield move through the apparatus, the current and voltage are measured to determine the impedance of the circuit. Changes in impedance are monitored, indicating variations in the quality of the strand shield.
Another significant patent is the On-line Switching Between Two Control Parameters. This control method and circuit facilitate a smooth transition between two regulating modes involving one active and one inactive parameter. The method includes providing a reference signal and developing a signal representing the inactive parameter. These signals are compared to generate an inactive output signal indicative of any differences. The active parameter is then compared to this output signal, allowing for a continuous adjustment without disturbing the system.
