A driving circuit electrically coupled between a first data line and a second data line and between a first scan line and a second scan line. The random number generation circuit includes a random number control circuit configured to generate a random number parameter based on data which is read out from the memory cell by a generated control parameter, and a pseudo-random number generation circuit configured to generate the random number by using the random number parameter as a seed value. An impact member formed of a plastically deformable material may be positioned with the inner face sheet within an area of the leading edge. Once vehicles are identified, the present method and system provides for three alternative embodiments of methods for determining the stopped delay for an entire image or for a particular vehicle.
