Methods of Monitoring Physiological Properties
First Claim
1. A method of monitoring at least one physiological property of an organism, comprising:
- directing energy at a first skin region of the organism and at a second skin region adjacent the first skin region;
detecting an energy response signal from the first skin region and an energy response signal from the second skin region, wherein both energy response signals contain information about blood flow and skin motion; and
processing the energy response signals to produce an extracted energy response signal containing cleaner blood flow information,wherein the directing, detecting and processing steps are performed by a device worn by the organism.

Abstract
A method of monitoring at least one physiological property of an organism includes directing energy at a first skin region of the organism and at a second skin region adjacent the first skin region, and detecting an energy response signal from the first skin region and an energy response signal from the second skin region, wherein both energy response signals contain information about blood flow and skin motion. The energy response signals are processed to produce an extracted energy response signal containing cleaner blood flow information. The extracted energy response signal may be compared with a physiological model to assess a physiological condition of the organism.
