A window panel having an elongated aperture with a height that embraces one to three lines of printed text removably slides into the interior region upon one set of tracks. An obscuring panel slidably enters the other set of tracks and enables controllable visualization of a few words per line of exposed text."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device for teaching reading skills","description":"A device for teaching reading skills employs a frame of rectangular configuration having an open interior region bounded in part by spaced apart parallel struts having paired grooves which function as","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8480400","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.
