The RFID system (12) comprises an RFID reader (28) and at least one antenna (34a-34i) for transmitting and receiving RF signals to communicate with the RFID tags. The system (12) further includes an electronic switch (38), preferably a FET switch, interposed between the RFID reader and the at least one antenna (34a-34i) to connect a particular antenna (34a-34i) to the RFID reader (28) and transmit RF signals from the antenna (34a-34i) to the RFID tags. The switch (38) is controlled to intermittently connect the antenna (34a-34i) to the RFID reader (28) to regulate the power of the RF signal transmitted from the antenna (34a-34i). The system enables an RFID tag to operate at low temperatures. Preferably the switch (38) and antenna (34a-34i) are integrated together, and in particular integrated into a shelf (22) of the storage unit (10)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"RFID monitoring system","description":"A radio frequency identification (RFID) monitoring system (12) for monitoring a plurality of RFID tags, and in particular for monitoring a plurality of vials incorporating such tags and stored at a lo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8502645","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.
