My patents: Being Applied for (so far, none have turned into a real patent)
Note: the latest four have been my original inventions, althought the one at Schlumberger has my friend as lead inventor since he wrote the patent and expanded on my original idea (the other coinventer created the proof of concept prototype).
My open source contribution: Cyberflex Access Starter Kit. While I was working for Schlumberger, I enhanced the original smart card kit on Linux to work with the latest card available at that time.
