  • Apparatus and method for distinguishing events which collectively exceed chance expectations and thereby controlling an output
    Patent number: 5830064
    Abstract: A method and apparatus of generating values and detecting whether the values fall outside chance probabilities. In one embodiment, a random-noise source provides a signal that is amplified, conditioned, and sampled to provide a series of random numbers. In one embodiment, conditioning includes inverting some of the values according to a pseudo-random sequence mask in order to remove certain first-order bias. Another aspect of this invention is to perform a statistical analysis of the values generated, and to control an output based in whether or not a chance expectation has been exceeded, or by the probability of a certain result obtained. Yet another aspect is to control a toy, game, appliance, or computer display based on whether or not a chance expectation has been exceeded by a measured sequence of values.
