Abstract: Systems and methods for classifying a condition of an entity including a conductive medium having multiple conductive paths, including use of a pattern recognition strategy to classify a signature constructed from impedance-interrogation measurements, optionally including inputs from other informative sources which may be external to the system, and optionally applying pattern recognition classification methods to aggregates of such signatures.

Abstract: Embodiments of systems and methods are disclosed for classifying a condition of an entity comprising a conductive medium having multiple conductive paths, using a pattern recognition strategy to classify a signature constructed from impedance-interrogation measurements.

Abstract: Methods and apparatus are disclosed for estimating a measure of a localized impedance property of a continuous conductive medium or other conductive system presenting a plurality of conductive paths, and for using such measures to compute a spatial distribution and/or image of impedance properties.
