Abstract:
1. A method for processing a signal to identify a consistent portion of the signal, comprising: obtaining a photoplethysmograph (PPG) signal from a sensor; selecting, using a processor, a current portion of the PPG signal for analysis; identifying, using the processor, one or more signal peaks in the current portion of the PPG signal; processing, using the processor, the one or more signal peaks based on a consistency metric; comparing, using the processor, the processed one or more signal peaks to the consistency metric to determine if the current portion of the PPG signal is consistent; responsive to determining that the current portion of the PPG signal is consistent, responsive to determining that the current portion of the PPG signal is not consistent, selecting, using the processor, a next portion of the PPG signal for analysis.
