Characteristics of time varying data, such as an electrical signal, are analyzed by converting the data from a temporal domain into a spatial domain pattern. Fractal analysis is performed on the spatial domain pattern, thereby producing a fractal dimension DF. The fractal dimension indicates the regularity...http://www.google.es/patents/US6422998?utm_source=gb-gplus-sharePatente US6422998 - Fractal analysis of time varying data
