Introduction
Robert L Sproston, Jr. is an accomplished inventor based in Mt. Prospect, IL (US). He is known for his significant contributions to the field of television technology. His innovative work has led to the development of a unique patent that addresses specific challenges in television signal processing.
Latest Patents
Sproston holds a patent for a "Decoder lockout defeat circuit." This invention features a suppressed sync television decoder that utilizes a phase locked horizontal oscillator. The oscillator controls the operation of a suppressed sync detector, which restores suppressed sync in a television signal. The restored sync is then coupled to the phase locked oscillator and a first four-bit counter. A second four-bit counter receives the horizontal oscillator signal and inhibits counting in both counters when it reaches 16. A reset signal, corresponding to the end of the vertical interval, initializes both counters. If the second counter counts fewer than 16 sync pulses, an error signal is generated. After thirty-two error signals, a defeat pulse is produced to unlock the oscillator.
