Energizing the coil in a first manner causes the rotatable magnet to rotate from a first position to a second position and energizing the coil in a second manner returns the magnet to the first position, causing the flag to alternately block and expose the optical sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Shutter for an infrared camera","description":"A shutter for an optical system, such as a small infrared camera, for alternately blocking and exposing an optical sensor to light includes an electrically conductive coil, having a center long axis, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9798220","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.
