    System and Sensor for RFID-Enabled Information Collection (2018)
    In:  CASI
    Details
    Publication Date: 2019-08-28
    Description: A system and sensor provides for radio frequency identification (RFID)-enabled information collection. The system includes a ring-shaped element and an antenna. The ring-shaped element includes a conductive ring and an RFID integrated circuit. The antenna is spaced apart from the ring-shaped element and defines an electrically-conductive path commensurate in size and shape to at least a portion of the conductive ring. In an alternate embodiment, the sensor system further comprises a reference ring-shaped element in a fixed relationship with respect to the antenna, with the reference ring-shaped element defining another series circuit to include an electrically-conductive reference ring and a reference RFID integrated circuit. The system may include an interrogator for energizing the ring-shaped element and receiving a data transmission from the RFID integrated circuit that has been energized for further processing by a processor.

    System and Method for RFID-Enabled Information Collection (2016)
    In:  CASI
    Details
    Publication Date: 2019-08-28
    Description: Methods, apparatuses and systems for radio frequency identification (RFID)-enabled information collection are disclosed, including an enclosure, a collector coupled to the enclosure, an interrogator, a processor, and one or more RFID field sensors, each having an individual identification, disposed within the enclosure. In operation, the interrogator transmits an incident signal to the collector, causing the collector to generate an electromagnetic field within the enclosure. The electromagnetic field is affected by one or more influences. RFID sensors respond to the electromagnetic field by transmitting reflected signals containing the individual identifications of the responding RFID sensors to the interrogator. The interrogator receives the reflected signals, measures one or more returned signal strength indications ("RSSI") of the reflected signals and sends the RSSI measurements and identification of the responding RFID sensors to the processor to determine one or more facts about the influences. Other embodiments are also described.
