Image Number 7 for United States Patent #4247107.

An electronically controlled roadrace system with a sound generator for penetrating a variety of audible signals is disclosed. The system includes facilities for starting the race, counting and displaying laps completed for each car, computing and displaying fastest lap times and last lap times for each car, calculating and displaying the remaining fuel for each car, introducing random failures for each car, and randomly determining one of several failure modes. Apparatus for selectively powering and depowering each track, upon signal from a controller, is shown. Also shown is a novel apparatus for sensing completion of another lap by each car, and a track section of each car track which is selectively decoupled from the track power for performance of pit functions.Other features and functions are disclosed.
