David Duehren's Problem Solving Experience:

1. I have 5 patents in the area of circuit design and telecommunications. See below
2. developed standard protocols for sending fax over the internet in "real-time". Included packet redundancy.
3. Adaptive call progress using pattern classifiers instead of a lookup dictionary.
4. Others that aren't as memorable in circuit design, and implementation
5. Line-preserving binary image compression to convert both horizontal and vertical dimensions of faxes from one resolution to another
6. Converted development process from hardware centric to software centric. From waterfall to pre-agile (time-based releases with continuous testing, and always running code).
