12. Infrared Systems Matt Simons

13. What is Opticom? Opticom is a traffic light preemption system currently used by emergency vehicles to quickly maneuver intersections Utilizes a powerful IR beacon mounted on the emergency vehicle 2 ft. IR sensors are mounted on the traffic lights 14Hz frequency, newer systems feature authentication 4 in.

14. Reduced speed zone beacon Placed in construction zones, school zones, accident scenes or anywhere a driving hazard exists User configurable via buttons and seven segment displays Features alerts for school zone, construction zone, accident scene, and special event.

15. Beacon details Utilizes peak wavelength of 950nm at 38kHz, High power emitters, estimate 1500ft line of sight range Encodes information into RC-5 similar protocol 41 high power emitters Flexible power supply

16. MirrorMate IR receiver Two different frequency receivers to accommodate the Opticom system (14Hz) and the reduced speed zone beacon (38kHz) The 14Hz signal will be detected via photodiodes, band pass filters, and firmware The 38kHz signal will be decoded using integrated IR receiver/decoders. The encoded data will be interpreted by the MCU Four directional receivers located in the bottom of the mirror determine direction

18. Bluetooth Systems Jake Hochstadt

19. Bluetooth Hardware Current: 8mA – 40mA Voltage: 3 - 4.2 V Benefits Inexpensive Ease of use Detriments Chinese part HC-05 Bluetooth Serial Module

21. Initial Bluetooth Configuration AT+ROLE=0 AT+CMODE=1 AT+UART=9600

22. Android Development Phones Motorola Photon 4g Android (2.3) Bluetooth: v2.1 Screen Size: 4.3 inches Motorola Defy Android (2.3) Bluetooth: v2.1 Screen Size: 3.7 inches

23. Bluetooth Software Android API www.developer.android.com Important Classes BluetoothAdapter BluetoothServerSocket

24. Android Application Ryan Moreland

26. Android Development Application written in Java for Android version 2.3.4 (Gingerbread) Backwards compatible with all future Android versions Android holds approximately 75% of the U.S. market share

27. Android Development Written utilizing the Google Distance Matrix API Google Maps JavaScript API Google Maps Android API Android Bluetooth API

28. Power MirrorMate will operate on any standard 12V automotive charging system. MirrorMate requires 3.3V for all components. This voltage will be created by a simple power supply consisting of a commercially available voltage regulator. (LM1085) Construction zone beacon requires 5V, it will use multiple LM1084 regulators to power the microcontroller and the large current requirements of the emitters. Ensures constant voltage for emitters regardless of input voltage

29. Budget and Financing $243.43 spent so far Assistance expected from Microchip Assistance from family members Expected total budged to fall below $1500
