Title: Seyed H Hashemi: Innovator in Data Transfer Protection

Introduction

Seyed H Hashemi is a notable inventor based in Mission Viejo, CA (US). He has made significant contributions to the field of data transfer protection, holding a total of 7 patents. His work focuses on enhancing the reliability and efficiency of digital communication systems.

Latest Patents

One of his latest patents is a system for data transfer protection during module communication. This innovation involves a plurality of digital modules connected by a Futurebus Plus common system bus, allowing for seamless data transfer between modules. The sending module transmits address and message data, while each module includes a Longitudinal Redundancy Checker. This mechanism ensures that data integrity is maintained, as the sending module transmits a first check word, which is verified by the receiving module's generated second check word. If the check words match, the data is accepted as good, enabling continuous network operation even when new digital modules are added or removed.

Another significant patent by Hashemi is a fault-tolerant digital computer system featuring two processors. In this multiprocessor system, one processor acts as the master while the other serves as a slave or shadow processor, monitoring the first processor's operations. The system periodically switches the roles of the processors, ensuring that both are functioning correctly and enhancing overall system reliability.
