The device consists of the following main components. GPS receiver High preformance microcontroller OLED display (green color) Power supply High speed memory unit for database storage The microcontroller receives the current vehicle position using the GPS. The device displays the current position and time on the display. The microcontroller then calculates an area of interest around the vehicle. When the mikrocontrollor has calculated the area of interest it checks in the database if any camera is within that area. The database is stored in an high speed memory unit for fast communication and camera detection. If a camera is within the area of interest a warning text will start blinking on the display. That speed limit for the camera will also be displayed on the display. The text will continue blinking until the camera no longer is within the area of interest. The maximum start up time for the GPS is 40 seconds, but it will normally start sending positions after 10-20 seconds. The variation in time depends on the level of obstacles in the near area of the GPS. The database can be updated using a standard PC, serial cable and a terminal software. More information about updating the database can be found here.
