Volumetric Physiological Measuring System and Method

摘要

A system and method for measuring volumes and areas using electromagnetic induction techniques. A current is generated and fed into one of two coil assemblies to induce voltage into another coil assembly to provide accurate values for volume or area.

1. A device for measuring the movement of an object comprising:
a. means for creating time-varying magnetic fields at least large enough to surround the object; b. electrical circuits adapted to conform to the surface of the object; c. noise reduction circuit means for reducing the sum of signals from an unwanted magnetic field of uniform intensity that is influencing the fields created to surround the object to zero; and d. voltage monitoring means connected to the electrical circuits, whereby motion of the surface creates a measurable change in induced voltage in the circuits that correlates to the movement of the object.
