Abstract
The current invention is an improvement to the random number generator described in U.S. Pat. No. 5,088,737. Random digits are generated by mixing ten differently colored balls in a transparent chamber. The entire surfaces of all the balls are uniformly colored and unmarked. None of the balls contains any electronic identification devices. A color sensor mounted near the settlement pocket of the mixing chamber emits data that is unique for each ball. A miniature computer and novel software correlate the data emitted for each of the ten balls with a different digit. One of the balls is randomly separated from the others and comes to rest near the color sensor without human intervention. The computer and its software record the digit that is correlated with the randomly separated ball and command a mini-projector to display the digit on the ball's surface in an upright position.
