Patent ID: 8843186

Claim:
A non-invasive glucose measuring apparatus comprising: an elongated housing configured to present an oscillating, non-uniform electric field onto a predetermined part of a human body; said housing containing first and second electrodes, the first electrode being arcuate; the second electrode being substantially centered in said arcuate first electrode, wherein said electrodes are configured to generate the non-uniform electric field near the arcuate electrode and the center electrode when the electrodes are connected to an oscillating electrical power source; a light source said elongated housing also configured to present a collimated light beam generated by the light source onto said predetermined part and to direct light scattered from said part into a detector; a processor in communication with said detector, said processor executing a program that produces an autocorrelation related to said scattered light; said program comparing said autocorrelation, or a function of said autocorrelation, against a predetermined calibration to determine a glucose level.
