The friction-coefficient estimating device comprises an irradiating unit including a first irradiating unit and a second irradiating unit, a specularly-reflected light receiving unit including a first specularly-reflected light receiving unit that receives a first specularly-reflected light component of a reflected light and detects a first specularly-reflected light intensity and a second specularly-reflected light receiving unit that receives a second specularly-reflected light component of a reflected light and detects a second specularly-reflected light intensity, and a diffusely-reflected light receiving unit that receives a diffusely-reflected light component of a reflected light and detects a diffusely-reflected light intensity, and a control unit that estimates a friction coefficient of the surface based on a first reflected-light intensity coefficient and a second reflected-light intensity coefficient."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Friction-coefficient estimating device and friction-coefficient estimating method","description":"A friction-coefficient estimating device is configured to estimate friction coefficient of the surface of a medium in a form of a sheet by irradiating a light on the surface and by detecting specularl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8508750","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.
