My time at ITIV (and beyond)
EE student at Fridericiana from 1954 to 1959
Back to ITIV as researcher in 1965 (Ph.D. in 1969)
(ITIV founded in 1958 by Karl Steinbuch)
1970 to “Informatik” with several ITIV colleagues
1972 Klaus D. Müller-Glaser’s Diploma Thesis work
1977 Ordinarius at Kaiserslautern(also from Karlsruhe: Avenhaus, Beister, Brakhage, Mayer, Nehmer, Pandit, Rupprecht, Siekmann, Wendt, Wippermann, and more)
2003: “entpflichtet” – why not Klaus ?

ITIV founded by Karl Steinbuch
EE is notorious for its powerful mathematical methods which have nothing to do with electricityThis is not surprising, for the science of logically prescribed actions has yet no home of its own[remarks by a book review in 1959]
logic design and computer architecture:a good
translation
(1958) from telephone switching networks (Oberpostrat Münch) to

Ph.D. thesis by Klaus …… an early component of the LOGE
system:
Quickturn Design System Inc.*, Mountain View, CA
*) vendor of ASIC emulators
important in a lawsuite against a patent about avoiding routing
congestion .
officially appointed by the “Bundesgerichtshof“ (in its role as Europe‘s highestpatent court) as an expert …… I found the solution by studying the LOGE manual
Suitor: Avant! Corporation, Fremont, CA – against:

Routing Congestion
a path usable only by a single signal
(a bridge which may be passed only once)
routing congestion: for instance, C can‘t be connected to D

Quickturn: detours needed ?
direct connection impossible
detour connectiom
rout thru

Euler‘s Koenigsberg Bridges Problem
cross each bridge exactly once !
which tour?

The problem cannot be solved

Adding 3 more bridges (8, 9, 10)
now the problem can be solved!

Ph.D. thesis by Klaus …… early component for the LOGE system
The patent claims have been met already by an interconnect scheme published in 1952
as the expert I argued for nullifying the patent
W. A. Malthaler, Earle Vaughan: An Experimental Electronically Controlled Automatic Switching System; Bell System Technical Journal, May 1952
I found the solution by studying the LOGE manual

Klaus at ITIV and beyond …
… by personal interaction and studying his memos and papers we often received valuable stimuli …
