The enclosure is positioned over a section of the conveyor belt, such that the plurality of cartons on the conveyor belt pass directly through the enclosure. The read chamber device that may be positioned centrally to the enclosure and projects a read zone via an antenna positioned centrally within the read chamber device. The read chamber device provides for tuning the read zone via a movable metal plate comprising absorber material components secured to it, that is positioned at variable distances to partially or fully cover the read zone. The metal plate is moved into the read zone to obstruct a percentage of radio frequency energy from escaping the read zone, and thus narrowing the total read field."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"RFID variable aperture read chamber crossfire","description":"A read chamber device disclosed for use within a radio frequency identification (RFID) scanning enclosure which provides a means of reading a plurality of cartons moving through the enclosure via a co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9830486","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.
