    1. 1. MuFUwECoRe <ul><li>Multifunction Underwater Environmental Condition Recorder </li></ul>
    2. 2. The Team Multi-Function Underwater Environmental Condition Recorder Team <ul><li>MuFUsoftCoRe MuFUhardCoRe </li></ul><ul><li>Mikey S. Siegel Rick Bal </li></ul><ul><li>Felix Lawi Andrew W. Hill </li></ul><ul><li>Dev Gopalkrishnan Ben P. McIntosh </li></ul>
    3. 3. Overview <ul><li>We are redesigning a bio-logger to record underwater behavior of elephant seals and other marine mammals </li></ul><ul><li>It is expected to be able to: </li></ul><ul><ul><li>Function continuously for 1 year </li></ul></ul><ul><ul><li>Withstand pressure of 2MPa (3000 psi) </li></ul></ul><ul><ul><li>Function accurately at 0°C - 40°C </li></ul></ul><ul><ul><li>Fit comfortably on an elephant seal’s head </li></ul></ul>
    4. 4. Elephant Seals <ul><li>Travel twice a year up to 12,000 miles </li></ul><ul><li>Return twice a year to molt and breed </li></ul><ul><li>Average dive is 600 meters for 30 minutes </li></ul><ul><li>Longest dives up to 1500 meters for 2 hours </li></ul>
    5. 5. Block diagram
    6. 6. Main Board Component Side Solder Side
    7. 7. Auxiliary Modules Cradle RF Board
    8. 8. Temperature and Salinity <ul><li>Most solar radiation is absorbed quickly </li></ul><ul><li>90% of ocean is below thermocline </li></ul><ul><li>Both temperature and salinity used for calibration </li></ul><ul><li>Used for physiological research </li></ul>
    9. 9. Temperature Sensor <ul><li>Analog Devices TMP37 </li></ul><ul><li>Uses bandgap sensor </li></ul><ul><li>Analog approach for compensation and control </li></ul>
    10. 10. Salinity Sensor <ul><li>Linear relationship between conductivity and ion concentration (i.e. salinity) </li></ul><ul><li>Salt water can be modeled as a resistor </li></ul>
    11. 11. Pressure <ul><li>An air filled balloon is 0.26% of original size at 1200 meters </li></ul><ul><li>Pressure and depth are linear </li></ul><ul><li>Also used for calibration </li></ul><ul><li>Again, provides physiological information </li></ul>
    12. 12. Pressure Sensor <ul><li>Keller Series 1 TAB </li></ul><ul><li>Tape Automated Bonding allows for high pressures </li></ul><ul><li>Again, analog for control and calibration </li></ul>
    13. 13. Accelerometers and Magnetometers <ul><li>Goal: Picture 3-D position and orientation </li></ul><ul><li>Compass system: 3-axis magnetometer + 2-axis accelerometer </li></ul><ul><li>Compass: determine heading (yaw) </li></ul><ul><li>Accelerometer: determine pitch and roll </li></ul>
    14. 14. Speed Sensor <ul><li>Flexible wire attached to strain gauge </li></ul><ul><li>Strain is proportional to water speed </li></ul>
    15. 15. Trimble Lassen IQ <ul><li>Low Power Consumption </li></ul><ul><li>Good Signal Acquisition Time </li></ul><ul><li>Dual Signal Acquisition Modes </li></ul><ul><li>Inexpensive </li></ul>
    16. 16. Wireless Data Acquisition <ul><li>Radiotronix Wi232 </li></ul><ul><li>Low Power consumption </li></ul><ul><li>Easy to use: </li></ul><ul><ul><li>Completely transparent </li></ul></ul><ul><ul><li>Only 4 signals needed </li></ul></ul>
    17. 17. RF Beeper <ul><li>Calibrated to 150MHz to match Wildlife Devices receiver </li></ul><ul><li>Uses crystal-locked phase loop for optimum frequency stability </li></ul>
    18. 18. Storage <ul><li>CompactFlash </li></ul><ul><ul><li>Open source </li></ul></ul><ul><ul><li>Large physically </li></ul></ul><ul><ul><li>High power draw </li></ul></ul><ul><li>MMC </li></ul><ul><ul><li>Low power </li></ul></ul><ul><ul><li>Physically small </li></ul></ul><ul><ul><li>Closed specification (acquired!) </li></ul></ul><ul><ul><li>Doesn’t work </li></ul></ul><ul><li>Secure Digital </li></ul><ul><ul><li>Like MMC (small, low power, closed specification) </li></ul></ul><ul><ul><li>Actually works </li></ul></ul>
    19. 19. User Interface <ul><li>Java GUI = platform independent </li></ul><ul><li>All access to Mufu is through identical AUI </li></ul><ul><li>Mode of communication is transparent to GUI (i.e. RF or serial) and Mufu </li></ul><ul><li>Infrastructure exists to make Mufu fully user customizable </li></ul>
    20. 20. Scheduling System <ul><li>Sampling Regime : Dictates the frequency of each task </li></ul><ul><li>Any task can be scheduled in this way including: </li></ul><ul><ul><li>Sensor reads </li></ul></ul><ul><ul><li>Memory writes </li></ul></ul><ul><ul><li>Battery power checks </li></ul></ul><ul><li>An arbitrary number of regimes can be defined </li></ul><ul><ul><li>Near surface of water </li></ul></ul><ul><ul><li>At surface of water </li></ul></ul><ul><ul><li>On beach </li></ul></ul><ul><li>User accessible regime switching is problematic </li></ul><ul><ul><li>Must be hand coded based on many factors </li></ul></ul><ul><ul><li>Must be logically consistent </li></ul></ul><ul><li>Tasks are passed to SST (Super Simple Tasker) RTOS for execution </li></ul>
    21. 21. Data Flow <ul><li>Data Collector stores sensor data in flexible, efficient form </li></ul><ul><li>Compression not yet implemented </li></ul><ul><li>Empty blocks are returned to Data Collector </li></ul><ul><li>Each component is a user controllable independent task </li></ul>
    22. 22. Task Distribution <ul><li>I didn’t do shit </li></ul>
    23. 23. Special Thanks <ul><li>Brent Wright, CMPE 123, Cyrus Bazeghi, Diana Robins, Erika Seagraves, Frank, Gabriel Elkaim, Guy Oliver, Hans Thomas, Anheuser-Busch, Jason Hassrick, Jo Chou, John Burr, Matt Kassawara, MBARI, Phuong Mai, Steve Petersen </li></ul>
