Abstract: A system, method and program product enable determining physiological characteristics of an animal. In one embodiment, the system includes a sensor having an array of electrodes for use in obtaining complex impedance data from a body part of an animal; and a determinater that compares the complex impedance data with an empirical data model to determine a physiological parameter of the animal, the empirical data model including physiological parameter data versus complex impedance data value correspondence of the animal.

Abstract: A system, method and program product for determining the in-place engineering properties such as density and moisture content of many varieties of engineering materials, are disclosed. The invention also includes a database, material model and sensor model for use with the above-described aspects. In one embodiment, the invention determines a compaction indication of the material based on an effect of impedance characteristics of the material on an electrical field, and corrects the compaction indication for at least one of a sensor depth-sensitivity inaccuracy and a compaction process inaccuracy. The compaction indication is determined based on a material model, and the corrections are based on mathematical and empirical models of the compaction process and the sensor.
