Abstract: A wearable device includes at least one physiological sensor configured to detect and/or measure physiological information from a subject over a period of time when the wearable device is worn by the subject, and a process or coupled to the sensor. The process or is configured to detect respective peaks in a physiological waveform representing the physiological information, compute probabilities for the respective peaks based on predetermined data indicative of one or more conditions, select a subset of the respective peaks based on the probabilities thereof as representing more accurate physiological information for the subject, and generate a physiological assessment of the subject based on the subset of the respective peaks that was selected. Related signal processing devices, methods of operation, and computer program products are also discussed.

Abstract: A method of identifying a best one of a plurality of photoplethysmography channels of a PPG sensor, wherein the PPG sensor includes at least one optical detector and a plurality of optical emitters that define the plurality of PPG channels, includes sensing PPG data from each of the plurality of PPG channels; processing the PPG data from each PPG channel, via the processor, to generate a plurality of PPG parameters; processing the PPG parameters, via a probabilistic model, to identify a best one io of the plurality of PPG channels.
