Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on the right, we value the items on the left more.”

Out of interest in computer vision and digital image processing, Jürgen developed an application that simulates human vision and thinking when playing the SET® card game. Assuming normal lighting conditions, the developed smartphone app not only finds the right solution before all other players but also all solutions.

The idea for this app emerged at Laurelwood Elementary School in Santa Clara, California. As a volunteer, Jürgen played the card game SET® with second-graders in math class as group work, which trains visual perception and logical thinking. He kept imagining how a smartphone could take over his role as a referee.
Based on this vision, Jürgen developed the smartphone app AI Card Player. The app recognizes the colors and symbols of the playing cards, calculates all permitted combinations, and presents the solution to the puzzle in a very clear and understandable way.
Most of the development has been finding a reliable way to recognize the colors and symbols of the playing cards and translating that model into efficient software. Interestingly, the visual perception of playing cards and the learning of the symbols is a relatively easy task for us humans, but they do not represent a trivial problem for a computer system. In contrast, the replication of logical thinking seems to be child's play for a computer system. The implementation of the rules of the game only accounted for a tiny fraction of the development effort.
You can find more information about the app at the web page AI Card Player.

In interdisciplinary engineering teams at BMW, Jürgen developed software for electronic systems (embedded systems) for steering and drive systems in vehicles. After working for many years in the development department, Jürgen researched methods for developing software and hardware for future drive-by-wire systems for his doctoral thesis and BMW.

In interdisciplinary engineering teams at BMW in Munich, Jürgen developed software for electronic control units (embedded systems) for steering and drive systems, which went into series production in the 3 and 7 series, for example.
His task was the development of real-time critical software systems that were used with different hardware configurations in many vehicle variants. The area of work included the creation of the first prototypes in the laboratory, the subsequent integration into the vehicle, system tests in the vehicle even under the most extreme climatic conditions and the support of the software systems after the start of series production.
The increasingly complex systems in vehicles, such as drive-by-wire systems, required the use of new methods and tools. In order to meet the significantly higher requirements for software and hardware, Jürgen developed and evaluated new approaches to developing such systems as part of his doctorate at the BMW Technology Office in Palo Alto, California.

General Motors (GM) in the USA was looking for a simulation model for distributed electronic control units (ECUs) in their vehicles. The overriding goal was to develop optimal system architectures for future vehicle models.
Together with Paolo Giusto, a scientist and engineer at the GM Advanced Technology Office in Palo Alto, California, Jürgen developed a model in the MLDesigner simulation program that can simulate the distributed ECUs. The heart of the model was a search algorithm that analyzed all possible communication channels and thus enabled a quantitative evaluation of different system architectures. Individually developed evaluation functions also allowed a simple analysis of the simulation results and rounded off the developed software package.
The simulation model, which is based on statistical methods, was accepted by the engineers and successfully used in the development department at GM.

In the start-up Crosstest,San Mateo, California, Jürgen and a small team developed a software tool that generates unit test cases for C/C++ functions. The tool supports software developers in testing their software functions in order to identify and eliminate errors in the code at an early stage. The CEO of Crosstest, Khalid Sebti, was very excited about a new software module that Jürgen was developing and remarked: “Jürgen, you have set the bar very high for us!”
With a similar goal in mind, Jürgen worked on a support team at Cisco Systems, San Jose, California. In the team, Jürgen developed shell scripts for test automation and general guidelines for testing software. Another important task of the team was to familiarize the software developers with these new tools and methods and to support them in their application.

A Berlin car trade service wanted a software program that would search the generated websites of an online vehicle market according to selected criteria (brand, price, etc.) and filter out contact addresses that were of interest to him from the flood of information.
A challenge in this project was the high number of requests to the web server of the online portal (more than 50,000) and the associated time delays or even interruptions by the web server.
The solution to the problem was to break queries into smaller units and save the intermediate results in a standard format. As a result, the data could ultimately be merged into the desired dealer lists, regardless of the Internet connection. The generated list can now be easily imported from a standard program, for example, Microsoft Excel or Apple Numbers, and displayed clearly as a table.
This solution made the software system not only more robust and scalable, but also faster.
