Title: Hiroshi Nagano: Innovator in Data Transmission Technologies

Introduction

Hiroshi Nagano is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of data transmission technologies, holding a total of 4 patents. His work focuses on improving communication systems, particularly in connectionless data transfer.

Latest Patents

One of Nagano's latest patents is titled "Method of and apparatus for realizing priority data transmissions for CSMA/CD system." This invention outlines a method for transmitting large amounts of data with priority in a CSMA/CD system. The process involves checking for free space on a transmission line in response to a data transmission request. If space is available, a priority transmission notice is sent from the source node to other nodes, allowing for efficient data transfer while disabling other nodes from transmitting during this process.

Another notable patent is the "Connectionless communication method." This invention establishes multiple datagram Virtual Circuit Connections (VCCs) for connectionless data transfer between adjacent exchanges. It allows an originating terminal to disassemble connectionless data into cells, inserting a leading cell that indicates the destination address. This method enhances the efficiency of data communication by utilizing a dedicated datagram VCC for the transfer.
