Title: The Innovative Mind of Sam G Cohen
Introduction
Sam G Cohen is a notable inventor based in Pleasantville, NY (US), recognized for his contributions to telecommunications technology. With a total of three patents to his name, Cohen has made significant advancements in the field, particularly in enhancing communication interfaces.
Latest Patents
Cohen's latest patents include an "Automatic line impedance balancing circuit for computer/telephone." This invention provides a data link for receiving and transmitting serial data via FSK modulated carrier signals over telephone lines to a computer. The design features an operational amplifier in a duplexer circuit with a variable impedance feedback circuit, which is automatically adjusted by a computer subroutine to compensate for variations in telephone company line impedance. This adjustment minimizes the amplitude of any transmitted carrier signal that might appear at the input of a conventional band pass filter for the receiver carrier signal.
Another significant patent is the "Terminal equipment ring/ding suppression circuit." This invention is part of a telecommunications network and includes ring suppress circuitry that prevents a ringing signal from dinging the bell in the terminal equipment until the calling party is identified. The microprocessor within the terminal equipment detects the ringing signal and activates a relay in the ring suppress circuitry to prevent the terminal bell from dinging. The suppression of the ding is achieved through two back-to-back zener diodes connected in series with the relay contact and between the tip and ring conductors of the terminal equipment.
