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