ABSTRACT:
An electric circuitry tests the memory and visual capabilities of a driver shutting off the engine if he fails in the test. Digits are flashed one at a time at random on a screen for the driver to memorize. A full set of digits is then flashed in numerical order one at a time for the driver to press a button when each of the memorized digits reappears on the screen.
