ABSTRACT:
A method for analyzing a signal. The signal is passed through a noise filter to generate a filtered signal. The filtered signal is passed through an adaptive pattern recognition unit. At the adaptive pattern recognition unit, a pattern that is a function of the filtered signal is predicted. A mathematical deviation in the filtered signal is detected by comparing the filtered signal with the predicted pattern. The detected mathematical deviation is flagged. The filtered signal is passed through at least two pattern recognition weighing units. At each pattern recognition weighing unit, the filtered signal at about the detected mathematical deviation is matched with a collection of stored patterns. A weight is assigned to each stored pattern. Each stored pattern and the assigned weight of the stored pattern are input to an expert system ranking unit. At the expert system ranking unit, one of the stored patterns is selected by applying a predefined set of generalized rules. Additionally, the method may determine if activity in a signal is individual event activity. A moment of chaos in the signal may also be determined.
