Title: The Innovative Contributions of Andre Lavigne
Introduction
Andre Lavigne is a notable inventor based in Montrouge, France. She has made significant contributions to the field of electronics, particularly in the development of technologies related to cathode ray tubes. With a total of two patents to her name, Lavigne's work has had a lasting impact on the industry.
Latest Patents
Lavigne's latest patents include a method and apparatus for automatically processing and correcting the blocking voltage of an electron gun. This invention involves periodically removing an input video signal and driving a cathode with a DC stabilizing voltage. A pulse perturbation is impressed upon a control grid, allowing the cathode to momentarily conduct more heavily to exceed a predetermined threshold. A feedback loop detects a response signal from the perturbation of cathode current, storing this signal in memory to determine the corrected blocking voltage during normal operation.
Another significant patent is for a blanking voltage generator for cathode ray tubes. This apparatus generates a blanking voltage for electron guns used in color television displays. It utilizes circuitry that includes a video voltage amplifier with a control input. A feedback loop modifies the blanking voltage in response to samples of the cathode current taken when the video signal is zero.
