Altenburger Technologies GmbH, is a company based in Seelbach in the Black Forest, Germany. The company makes some kind of electronic fittings that possibly control lighting in buildings.
They are included here because the name and, more tellingly, the corporate logo of Altenburger Technologies are so similar to those of the Altenburger company that made bicycle components. Could they possibly be related? Seelbach is about 120km north of Jestetten (the home of the bicycle component company), but is still very much in the (rather wealthy) badlands of southern Baden-Württemberg.
