A detecting method using the earphone by a participant includes the steps of: the participant inserts the earplug in the ear canal thereof; the light sensing module senses the changes of light emitted through the window and then reflected by the wall of the ear canal; the light processing module processes the reflected light changes to get photoplethysmography (PPG) signals; and the signal processing module receives and processes the PPG signals to get physiological information of the participant."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Physiological function detecting earphone and detecting method thereof","description":"A physiological function detecting earphone includes an earphone body, an earplug mounted at one side of the earphone body and defining a window, a light processing module including a light sensing mo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9675259","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
