Title: The Innovations of Robert P. Logan
Introduction
Robert P. Logan is a notable inventor based in Framingham, MA, with a significant contribution to the field of electronics. He holds three patents that showcase his expertise and innovative spirit. His work primarily focuses on advancements in circuitry and cathode ray tube technology.
Latest Patents
One of Logan's latest patents is for a time-shared sample and hold circuit. This invention implements at least two amplitude level detectors and a method for monitoring their ability to track rapid changes in signal level. The monitoring circuit utilizes a delay network to indicate when the detectors have not been driven into conduction during a specific time interval. If this condition persists, a resetting circuit discharges the detector output filter network, allowing the detectors to re-establish an output indicative of the present input signal level. Additionally, he has developed an apparatus for adjusting operating conditions of a cathode ray tube. This apparatus in a color television receiver includes a matrix and amplifier circuit coupled to a chrominance signal source, which is selectively connected by a 'service-normal' switch to a luminance or reference signal source. The matrixing and amplifying circuit features a control grid DC bias potential development circuit and a cathode DC bias potential adjusting circuit, ensuring optimal performance of the cathode ray tube.
