A surface irregularity enhanced image is generated by subjecting this tire inner surface image to spatial frequency processing using a low-pass filter for the tire width direction and a band-pass filter for the tire circumferential direction. A determination is made of whether a recessed region exists which indicates a bonding defect of the end portions of the sheet member."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for detecting material bonding problems inside tire","description":"From three-dimensional numerical data of surface irregularities of a tire inner surface in a tire of a construction where a sheet member is disposed on the tire circumference, a tire inner surface ima","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9815248","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.
