Career Overview W.John Guineau 5/2007
Professional Summary • Over 25 years in software industry • Hardware background • Software career • Embedded Systems to GUI, Web • Many O/S, many languages, technologies • Hardware & Software design • Inventions – e.g. Wireless GPS tracking
Digital Equipment Corp. • Just a kid • Hardware Tech turned Software Engineer • VMDD - Disk/Tape/CDROM Diagnostics • Vast improvement over industry products • Industry leaders for SCSI • ITECS – Complete automation • IEEE-488 power supplies, Tenney environmental chambers, Lots of uVAX IIs and PRO-350/380s • Reduced days to hours, with summary • Industry wanted to buy it!
DEC - VMS - Modeling Disk I/O • Multi-process, concurrent I/O + • High-speed Storage (RAID) + • Throughput and Latency requirements = • Problem: Traffic Jam! • Solution: Analysis, modeling, adaptivity • Software: Data collection & Visualization • Result: > 300% performance improvement • U.S. Patent 5,426,736
Flattening of surface implies saturation Additional I/O load beyond saturation results in latency Visual inspection provides solution! It can be modeled: What the data tells us n*q K*q Tmin= ------- + ------ + C R Z n = size of request q = number of requests R = bus bandwidth K = avg. access time Z = queuing efficiency
What to do? – adaptive algorithm • The mathematical model gives us the limits • The driver implements the algorithm t’ * RZ q(n,t’) = ------------- nZ + KR t’ = Desired worst case response time
Industry – Process Control • ASTM Strength of Materials Testing • Real-time control for materials validation • Data collection, visualization • Analysis, automatic determination, interactive • Vastly improved process capabilities • HIP Furnaces • PID and the momentum of heat • Bad motor? You can hear it! • Microphone, FFT, compare and sort
Commercial – Video Conferencing • AVID Technology – StoryBase • Windows in a Mac world • CU-SeeMe • Cornell University experiment turned shrink-wrap • Quartz, ActiveMovie and Video • Beat Microsoft to capture implementation! • DirectShow • Network Packetization and Re-assembly • Ordering and window of opportunity • Significant improvement over data loss
NASA? Are you kidding? • Just married, 6 month old daughter… • We’re going to California!
NASA JPL – JASON-1 • Satellite, Low Earth Orbit (200 - 500 miles) • “Earth-observing” – Monitors Earth’s Oceans • Follow-on to TOPEX/Poseidon – ‘El Nino’ • Joint project - NASA and CNES (France) • Launched Dec 7th, 2001 • Deemed “Extremely Successful” so far
Jason-1 High-Level Context JASON-1 Ground System – JTCCS Sequencing, Science Data Earth Terminals Science Communities Data Archives

Network
JTCCS – Major Innovation • Entire system runs on a 400mhz laptop! • Almost 500K lines of code • JPL’s first-ever “lights-out” spacecraft automation • JPL’s first-ever wireless hand-held spacecraft control • Private demonstration to lab director • NASA Software of the Year competition • Honorable mention
My Own Computer • Z80 • ZX81 inspired • Custom firmware • Weather sensors • Dallas 1-Wire • Humidity • Temperature • Pressure
The Tracker • Hand-held device • 2-way radio (paging) • GPS • AVR Microcontroller • Other sensors (fall detection, heart rate) • Don’t leave home without it • Never be lost again! • SAR wanted it • No funding
Launch? Oh No! • Jason-1 Project Complete • Three months after “9/11” • Add a 2 yr old son • And I’m out of a job! • Coyote Technology, Inc. • Sub-contract to JPL • Amgen
Back in Business • SharedNet • Military “Situational Awareness” • It will never work • DoD/DISA – Network Topology • Locked in a room – “Come up with something new” • XML, Jini -> SOAP and WebServices • Avionics Simulator • Europa Pathfinder and X2000 • Team-X – Spacecraft & Mission Design • ICEMaker - NASA-wide distributed design collaboration
Amgen • Biotech – Work with scientists! • Data processing/analysis/visualization • AmgenFramework • Reusable component library • Windows, C#, .Net • MANY applications, huge demand • Immunology, Inflammation, Hematology, Oncology, Legal • Electrophysiology, Mass-spectrometry • Corporate Databases for research tracking
JPL - Robotics • Mars Rover Simulation • ROAMS • Kinematics, Dynamics • SimScape • 2.5D/3D topographic simulation • Layered surfaces • Surface Properties • Planetary support
JPL Robotics • Laser Scanner • Mars Yard • Terrain reconstruction from noisy data
JPL Robotics • Research Mars Rovers – real hardware! • FIDO, Rocky8, CLARAty, vxWorks • Ported to Linux, w/hi-res timer patches • PID loops verified on scope • Debugging software with hardware • Drove rover around Mars Yard • Under Linux 2.6! • With my own custom kernel
JPL – Flight Software • I finally made it. • MSAP - Multi-mission System Architecture Platform • Reusable baseline • Avionics hardware and flight software • Basis for MSL – Next Mars Rover • Mil Std. 1553 - system core • Hard real-time, mission critical • Questionable future • Mindset • Legacy/MER inheritance • Institutional • Profit/Loss - no real consequences
Around the Home • Home Automation • Multi-camera surveillance system • High-end Weather station • Ozone (O3) monitor • Off-the shelf sensor • ADC, S/W, ASPX • Earthquake Monitor • 3-axis accelerometer • ADC, S/W, ASPX • Cell phone apps
Conclusion • Man WILL go back to the Moon & to Mars • Commercially viable discovery will change the game • For me, it’s been a blast! • My best years are yet to come • Questions?
