1. 1 Electrical and Computer Engineering Comprehensive Design Review February 12, 2010 Team Zink Nicholas Cipriano, Ali Jameel, Jeremy Mestancik, Brian Simakauskas

2. 2 Electrical and Computer Engineering Overview  Our advertising system allows advertisements to be scheduled and uploaded over the Internet  Advertisements are automatically sent to their corresponding buses  Ads are displayed based depending the current time and location of each bus

3. 3 Electrical and Computer Engineering Block Diagram

4. 4 Electrical and Computer Engineering Website  Allows users to log in, view scheduled ads  Displays the correct schedule for a given date and bus route schedule.txt contains all dates for reduced schedule and no service  User can choose individual bus runs to advertise During peak hours, buses run frequently – Users will select time ranges rather than bus runs

5. 5 Electrical and Computer Engineering Homepage

6. 6 Electrical and Computer Engineering Schedule Page

7. 7 Electrical and Computer Engineering Client update_schedule.sh daemon  At regular intervals, bus connects to server Connection requires no password  Bus retrieves updated schedule.txt file from web server Updated file replaces the old  Bus checks if filenames exist in local memory If not, bus downloads ad from server

8. 8 Electrical and Computer Engineering Google Map API  A map displays the bus route on the website  User is able to click points on the map, and the distance between those points is the ad distance  The selected interval is highlighted, for ease of use  The map displays the estimated time and distance of an interval

9. 9 Electrical and Computer Engineering New Maps Update on Monday

10. 10 Electrical and Computer Engineering Ad Displaying  The scheduling information for each ad is parsed into structs called ads  These structs hold all the information relevant to displaying an ad  A struct is also constructed for the GPS coordinates  Having two structs makes comparing values and performing operations much more elegant

11. 11 Electrical and Computer Engineering Ad Displaying  For each GPS coordinate, the distance from an ads start coordinates and end coordinates is made  The Haversine function is used to calculate this distance  When the Haversine function returns a distance that is in a certain range, the ad is either displayed or turned off

12. 12 Electrical and Computer Engineering For FDR  Ad displaying priority  Ad scheduling priority  Default advertisement display  Full wireless communications  Bus communication with web server rather than host computer
