A system improves analysis, diagnosis and characterization of cardiac function signals based on cardiac electrophysiological activity momentum computation, characterization and mapping. A battery compartment can be disposed within one of the clamp arms. A cosmetic product reception indentation, which could comprise a supplemental product tube with a body portion within the applicator tip or a distal end cup, is disposed in an end face of the column core applicator tip, and that end face can be disposed at a miter angle.
