Noninvasive physiological analysis using excitation-sensor modules and related devices and methods
First Claim
1. A method of monitoring at least one physiological property of an organism, comprising:
- directing energy at a target region of the organism and at a region adjacent the target region, wherein the target region comprises more blood flow than the adjacent region;
detecting an energy response signal from the target region and an energy response signal from the adjacent region; and
processing the detected signals to produce an extracted energy response signal, comprising subtracting a signal associated with motion of the organism,wherein the directing, detecting and processing steps are performed by a device worn by the organism.

Abstract
Methods and apparatus for qualifying and quantifying excitation-dependent physiological information extracted from wearable sensors in the midst of interference from unwanted sources are provided. An organism is interrogated with at least one excitation energy, energy response signals from two or more distinct physiological regions are sensed, and these signals are processed to generate an extracted signal. The extracted signal is compared with a physiological model to qualify and/or quantify a physiological property. Additionally, important physiological information can be qualified and quantified by comparing the excitation wavelength-dependent response, measured via wearable sensors, with a physiological model.
