Method and apparatus for controlling the flow of a medium
First Claim
1. A system for controlling the flow of a medium across or through a region constrained by a primary solid that interferes with the flow of the medium, the system comprising:
- at least one sensor located in proximity to the primary solid for measuring and quantifying at least one flow parameter of the medium;
a processor coupled to the at least one sensor for calculating a time-varying measure of relative patternness for the medium in proximity to the primary solid, the measure of relative patternness including a quantification of approximate entropy; and
a secondary solid responsive to the time-varying measure of relative patternness to affect the flow of the medium in proximity to the primary solid.

Abstract
A quantification of approximate entropy is determined on a set of data by comparing subsets of the data. The comparison reveals the regularity and stability of similar patterns amongst subsets of the data. The comparisons perform such that the contribution of noise to measurement of the regularity and stability is minimized. Quantitative values are assigned to measure the degree of regularity and stability. From these quantitative values a single output measure is generated indicative of the amount of patternness of the sequence of data. The calculations required to determine this approximate entropy are preferably performed within a data processing system. Numerous peripheral devices may be attached to such a data processing system. The types of data for which the approximate entropy may be calculated include any sets of data wherein the amount of patternness is sought.
