HEALTH MONITORING SYSTEMS AND METHODS
First Claim
Patent Images
1. A method for health monitoring comprising:
- determining from a user'"'"'s ECG signal when heart beats occur;
time averaging each of two photoplethysmogram signals correlated to the beat locations;
generating ensemble averages;
using a linear regression of the ensemble averages to determine the linear gain factor between the two signals;
determining from the gain factor the patient oxygen saturation.

4. A method comprising:
-
selecting a possible gain value, multiplying the average frame signal by it, and determining the residual error with respect to an average frame of a different wavelength; and
,optionally, repeating the selecting, multiplying and determining operations for a number of potential gain values. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
