Sampling Pulse-Width-Modulation Codes on the Parallel Port

Introduction For an upcoming research project, I needed to get data streams from simple 2-axis accelerometers. There are usually two types of accelerometers: one type with analog outputs that need an ADC (analog-digitial converter) to sample, and another type with pulse-width modulation outputs. The latter has the advantage that it can be sampled with purely digital inputs like the standard parallel port of current PCs. Thus, the crazy idea of attaching accelerometers directly to the parallel port instead of using a micro controller was born.

Speech at Promotio sub auspiciis Praesidentis rei publicae

After finishing my doctoral studies in technical sciences with my final viva voce on 18.11.2004, I have been honored in my promotion (PhD graduation) on 29.11.2005 by the president of the Austrian republic. The Promotio sub auspiciis Praesidentis rei publicae is a special form of promotion specific to Austria and is dependent on the grades reached in school and at university (see Wikipedia). It was a great honor for me that our (at that time) current president, Dr.
