Apparatus and method for distinguishing events which collectively exceed chance expectations and thereby controlling an output
First Claim
1. A random event generator device (100) comprising:
- a noise-signal source (110) that provides a noise signal;
a sampler (116) coupled to the noise-signal source (110), wherein the sampler (116) outputs a series of digital data values (117) depending on a value determined from the noise signal;
a selective invertor (118) coupled to the sampler (116) that inverts some, but not all, of the series of digital data values (117) to produce a selectively inverted series of digital data values (119); and
a driver coupled to the selective invertor (118) and operable to provide a signal having values representative of the selectively inverted series of digital data values (119).

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.
