2. CS-EE 481 2 Agenda Introduction Emily McKaig Background Emily McKaig Methods Carolyn Farris Results Carolyn Farris & Steve Beyer Conclusions Steve Beyer Demonstration Team Wire Lettuce Founder’s Day University of Portland School of Engineering

3. CS-EE 481 3 Introduction The Team: –Steven Beyer (Fall Lead) –Carolyn Farris –Emily McKaig (Spring Lead) Our Supporters: –Dr. Joseph Hoffbeck (Adviser) –Dr. Tanya Crenshaw –Mr. John Turner (Industry Representative) –Mr. Keith Ehrensing (Portland Bureau of Transportation) –Mr. Charles Mooney Founder’s Day University of Portland School of Engineering

4. CS-EE 481 4 Background Current System at the Portland Bureau of Transportation (PBoT): Antiquated (VHS Tapes) Installation is difficult (weighs over 70 lbs) Requires frequent maintenance (lasts only 3 days between visits) Founder’s Day University of Portland School of Engineering

5. CS-EE 481 5 Objectives Improve the current system: Solar power Wirelessly transmit the video feed to PBoT Smaller, lighter components Founder’s Day University of Portland School of Engineering

6. CS-EE 481 6 Methods Design in the Fall Implementation in the Spring Scheduled Milestones Founder’s Day University of Portland School of Engineering

7. CS-EE 481 7 Methods: Fall Project Proposal Met with Client Functional Specification Researched Components Design Document Founder’s Day University of Portland School of Engineering

8. CS-EE 481 8 Methods: Spring Ordered Components Interfaced Network Device and Camera to Gumstix Power Testing Ordered Encasement Client Demonstration Founder’s Day University of Portland School of Engineering

9. CS-EE 481 9 Results: System Architecture Founder’s Day University of Portland School of Engineering

10. CS-EE 481 10 Results: Power Interfaced existing PBoT circuits to power the gumstix and camera Solar panel charges the battery Founder’s Day University of Portland School of Engineering

11. CS-EE 481 11 Results: Camera LinkSprite JPEG Color Camera TTL Interface Preset commands to take a picture and receive it Can set picture size and control how often a picture is taken to optimize for client needs Founder’s Day University of Portland School of Engineering

12. CS-EE 481 12 Results: Gumstix Processor “Brain” of the device Coordinates the receiving of the picture from the camera with sending the picture over the network Founder’s Day University of Portland School of Engineering

13. CS-EE 481 13 Results: Gumstix Software Founder’s Day University of Portland School of Engineering

14. CS-EE 481 14 Results: Storage on Base Unit The base unit is any computer with an internet connection All pictures are stored in a directory specified by the user For the client, this will be a machine at the PBoT Headquarters Founder’s Day University of Portland School of Engineering

15. CS-EE 481 15 Conclusions We have greatly improved the device: The user can access the video feed at a remote location, as the pictures are sent Device is much lighter Other improvements for future development Smaller, lighter battery Optimize software for more frames per minute Founder’s Day University of Portland School of Engineering
