Based on previous detection statuses of the non-light emitter and the light emitter, the control device sets a time ratio of a time of a non-light emitter detection mode to a time of a light emitter detection mode, and sets timings of the non-light emitter detection mode and the light emitter detection mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Position detection device, image display device and image display system","description":"A position detection device for detecting positions of a non-emitter and an emitter in a detection area includes one or more reflective members disposed around the detection area, illumination light s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10496221","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.
