WEARABLE LED SENSOR DEVICE CONFIGURED TO IDENTIFY A WEARER'S PULSE

摘要

A wearable sensor device can include at least one LED and a light sensor for generating a photoplethysmogram ("PPG") from light emitted by the at least one LED. The wearable sensor device can also include a processing unit that is configured to process the PPG to produce a highly reliable representation of the wearer's pulse.
