The environmental protection components may include air discharge assemblies, movable shields, guards, wipers or deflectors such as drip edges, water-accumulating textured surfaces, flow diverters, and selectively placed flanges or fixed guards which operate cooperatively to displace accumulated contaminates, debris, or liquids from the optical windows and adjacent sensor surfaces. A portion of the vehicle support surface or cover plate is removable to permit access to underlying components."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for environmental protection of drive-over tire tread depth optical sensors","description":"A drive-over tire tread depth measurement system is configured with environmental protection components for preventing or impeding environmental contaminates from falling through openings in a vehicle","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9677973","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.
