1988-1997 University Bremen
Graduation: diploma

Studies in electrical engineering at the University of Bremen/Germany.
Further studies in digital image processing in the field of communication and
digital engineering. The subject of my first main project (großes Arbeitsvorhaben
AV) was the computer-aided development of "Dual Offset Parabolic Antennas" (field
of high-frequency engineering / FORTRAN / vector based). Processing of 8 bit grey
value images by manipulating their histograms formed the basis of my second main
project (2. großes Arbeitsvorhaben AV / Borland C++ / DOS / XMS / Port C to C++).
I finished my studies in 1997 with a thesis on the subject "Realization of a
Universal Image Processing System for the Examination of Digital High-Speed
Imaging in the Field of Combustion Research". This project was prepared for and
together with the ZARM (Zentrum für angewandte Raumfahrttechnologie und
Microgravitation = Center for Applied Aerospace Technology and Microgravitation)
(Windows NT / OS/2 / Matrox-Framegrabber / Watcom C++).

OPENSOURCE...

Linux:    since 1994; Working with Slackware, RedHat, SuSE, Debian,

 Caldera and Knopix; Starting 2002 I build my own Linux, based

 on LFS (Linux From Scratch). All programms (kernel, drivers and

 user space progs) are build and optimized for Athlon XP by

 myself. Actualy running on an Athlon XP 1800+ PC and an Athlon

 XP-M 2400+ notebook, with Kernel 2.6.1 and gcc 3.2;  experiences

 of the linux kernel development (2.2.x; 2.4.x; 2.6.x)

Linux on dbox2:   dbox2 is a DVB-Satelite-Receiver build by Nokia, Philips and

 Sagem for the german pay TV provider "Premiere". The box is

 powered by a "PowerPC" (66MHz, 32 MB ram, 8 MB flash,

 SmartCard(APDU, ISO 7816)); I do error correction and enhancements

 for my own dbox2 like mpeg2 transfer to the host computer

 (server), performance optimisation, etc.; Build is done by a

 crosscompiler (C++) on an i386 Linux-PC; CVS;

Bluetooth:TCP/IP over Bluetooth (bluez, p3nfsd...); Connectivity between

 Symbian-Devices like the Nokia 3650 and Linux; Direct test and

 debugging on target by using p3nfsd; p3nfs is a tool for

 mounting the SymbianOS filesystem into the linux filesystemtree;

 bluetooth profiles of SymbianOS;

plptools Symbian port: plptools is a set of libraries and utilities for enabling

 Unix (mainly Linux) systems to communicate with a Psion palmtop

 (EPOC); While reengineering the communication between a Symbian60

 device (Nokia 3650) and a Windows PC, I have found many agreements

 between the Symbian and plptools protocol; Now I try to build a

 patch to use the plptools with Symbian devices;

CAPI on Linux:    Actualy I build a smal FAX-Server vor sending and retriving

 faximiles with CAPI; Hardware: AVM Fritzcard USB v.2; Software:

 Image processing and transformation from Postscript input format

 to the SFF output format and send/retrive by CAPI calls

 (Kdevelop 3.0 / QT / C++);

Porting the AVM-Driver: Porting the AVM Fritzcard ISDN USB v.2 driver (fcusb2.ko)

 to Linux kernel 2.6.7; In case of two errors in the USB

 architectur in kernel 2.6.7, it is not possible to use the

 original driver; I have found this errors and make some

 corrections in the AVM source code; This patch was send to AVM

 and published on my homepage; The driver is based on a precompiled

 hardwaredependent part and a C source code part to integrate

 the USB-Device into the kernel;

 

SymbianOS SDK:    experiences: C++ SDK on Linux (gcc for ARM-Processors);

 programming with the Nokia Series60 SDK; GUI is mostly done in

 Windows; testing and debugging in Linux (p3nfs; there is no 100%

 compatibility between the emulation under Windows and the real

 SymbianOS programs compiled by GCC) or on target by using

 CodeWarrior (Windows); Borland Mobile Studio (development and

 on target debugging; Linux and Windows); work in progress:

 "travel book" for SymbianOS;

Android: experiences: Android SDK on Linux;
  programming Andoid-Apps; ADT; root the G1/Dream;
