4. Analog Circuit Diagram University of Portland School of Engineering

5. Scorecard • March’s Accomplishments: • Finalized construction of prototype including: Display, System Clock, and Analog Circuitry, MOSIS chip • Successfully integrated MOSIS chip • Troubleshoot design flaws • Works of Asians!!! University of Portland School of Engineering

6. April Plans • Finalize the circuitry positioning in the case & mount the Sp02 female connector • Keep the prototype working properly • Founder’s Day Presentation! • Senior Design Post-mortem University of Portland School of Engineering

7. Milestones University of Portland School of Engineering

8. Concerns/Issues • Hope the device is robust enough to last to Founder’s Day (a few diodes have blown out) • We are all very busy, so working as a team is very key to bring this to completion University of Portland School of Engineering

9. Conclusions • Beginning to see the light at the end of the tunnel • The pieces have come together to make a working prototype • Questions? University of Portland School of Engineering
