Title: Jack R Duke: Innovator in Data Processing Technology
Introduction
Jack R Duke is a notable inventor based in San Marcos, CA (US). He has made significant contributions to the field of data processing technology, holding a total of 4 patents. His work has focused on enhancing the efficiency and functionality of data communication systems.
Latest Patents
One of Duke's latest patents is an "Activity Detector Usable with a Serial Data Link." This device is designed to detect the presence or absence of information transmission over a serial data link between a computer system and a peripheral device. When a data signal is present, the activity detector allows the signal to be transmitted to the computer system. Conversely, if no data signal is detected, the device decouples the input transmission link from the computer system and places an all-ones signal on the input line, adhering to the I/O protocol.
Another significant patent is for a "Data Processing System Having a Star Coupler with Contention Circuitry." This system features multiple subsystems linked by a star coupler, which includes contention circuitry to ensure that only one selected subsystem can transmit a message at any given time. The contention circuitry employs a conventional priority encode circuit to determine which subsystem's message is passed, prioritizing the first message received or the one with the highest relative priority if multiple messages arrive simultaneously.
