Peter Rupprich

He was introduced to the world of "thinking" machines, which would determine his professional destiny, at the lectures of Tihamér Nemes in 1959. At the Kandó Technical School in 1963, he built a light telephone that had previously only existed in fantasy novels.

As a student at the Faculty of Electrical Engineering of the Budapest University of Technology (BME), he participated as a demonstrator in the work of Professor Károly Simonyi's department from 1966. He led the evening exercises of the Theoretical Electricity subject for students, and also built a digital teaching machine as a student club assignment, and created a program suitable for checking circuit calculation tasks for the ODRA and RAZDAN computers.

After graduating from university, from 1969, as an assistant professor at the Department of Instrumentation and Measurement Technology, his main task was to teach and develop the subject Digital System Technology. He successfully incorporated the experiences of his research-development-construction activities in this field into the material of the lectures and exercises of the subject. He wrote teaching notes and developed new subjects (Digital Simulation, Digital Arithmetic).
His research area covered several areas of artificial intelligence, e.g. pattern recognition (the topic of his diploma project), adaptive systems, modeling and simulation of neural networks. He participated in several development tasks of the department (e.g. hybrid computer). The “digital clock sculpture” he created together with Mária Lugossy at the College of Applied Arts was also exhibited at the Milan Triennale.

From 1977, as the head of the department of the National Computer Company (OSZV), later the Computer Application Company (Számalk), his task was to ensure the professional training of approximately one thousand ESZR (Unified Computer System) computer specialists at home and abroad each year.
In 1980, he held a 9-week intensive course in China on the hardware of the ESZR R-55 machine, commissioned by the Robotron Training Center in Leipzig.

In 1982, he received a job offer from Control Data, the world's leading modem developer at the time. Instead, from 1983, under a cooperation agreement, and then from 1988, as a senior system developer at SIEMENS AG Kommunikationstechnik in Vienna, he contributed to the development of the most modern digital, later IP (Internet Protocol)-based telephone exchange product families - in the areas of remote diagnostics, speech processing and, above all, highly integrated subscriber modules. These telephone exchanges were put into operation in 72 countries around the world.
His activities focused primarily on digital signal processing, and he participated in the design of Turaya's new satellite telephone and the new, highly secure communications system for the New York City subway network. He also did pioneering work in the development of the company's first xDSL systems.

He was a member of the expert working groups dealing with the maintenance of SIEMENS' communications technology patents and the topic of network security.
