The internal reflection sensor provides a first output that has a characteristic that differs based on whether at least one raindrop is on the windshield. A scattered reflection sensor is situated to detect at least some of a second portion of the radiation reflecting from rain near the windshield or a substance on the windshield. The scattered reflection sensor provides a second output indicative of an amount of radiation incident on the scattered reflection sensor. A processor is configured to determine a condition of the windshield based on the first output and the second output."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dual mode optical rain sensing device","description":"An illustrative example embodiment of a device for detecting rain or a substance on a windshield includes at least one radiation source, an internal reflection sensor situated to detect at least some ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9840232","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.
