With this, there is achieved an optical sensor capable of maintaining both of measurement accuracy at short distance and measurement accuracy at long distance when a housing panel is present between the optical sensor and a detection target."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical sensor and electronic device","description":"An optical sensor of the present invention changes a light-emitting period of a light-emitting element and a period of a reference clock that is used by a time difference extracting circuit, depending","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11287518","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.
