Systems and methods for reading Radio Frequency Identified (RFID) tags. In an embodiment, an enclosure having, within it, an antenna and processor is provided. The processor may be configured to record tag observations for tag identifiers received by the antenna from RFID tags. For one or more time intervals, tag observations may be identified which satisfy a tag filter, and a confidence that RFID tags satisfying the tag filter were in the field of view of the antenna during the time interval may be computed based on the identified tag observations. According to an embodiment, reports for tag filters may be then generated using the computed confidences, and these reports may be transmitted to an external system over a network.

Pluggable small form-factor UHF RFID reader

A radio frequency identification wristband for attaching to a patient that has a band, a wristband housing attached to or integral with said band, one or more radio frequency identification tag(s) or tag inlay(s), an insulator material, wherein said wristband housing is adhered to said radio frequency identification tag or tag inlay, said radio frequency identification tag or tag inlay is adhered to an isolator material, and wherein said insulator material is nearest to the skin of the patient and insulates the radio frequency identification tag or tag inlay from the patient's skin.

UHF RFID wristband with a long read range

A Pluggable small form-factor UHF Radio Frequency ID reader having in an enclosure: a host CPU; volatile memory; non-volatile memory; power inputs; digital circuitry comprising the CPU and supporting components; analog circuitry comprising power and Radio Frequency components; one or more antennas; networking components; user interface components; debug and test components; WiFi subsystem; Radio Frequency ID subsystem; wherein said enclosure comprises thermal dissipation capacity, radio frequency transparency with WiFi and Radio Frequency ID antennas, provides protection from physical and radiofrequency forces, is mountable to an AC outlet and can also be mounted flush to a solid wall or surface or at an angle to a solid wall or surface, connectable to PoE or DC inputs, having a capacity to convert AC/DC current; Radio Frequency ID setting configurable, employs intelligent filtering and smoothing algorithms and transmits only relevant summarized information back over a network, and permits firmware management and real-time monitoring.

An architecture of an RFID system that facilitates the accessing of RFID tag data within an RFID environment. The architecture includes a plurality of RFID readers, each reader being operative to transmit a first RF signal for scanning at least one RFID tag disposed within an RF coverage region associated with the reader, and to receive at least one second RF signal including tag data in response to the scanning of the tag. The architecture further includes at least one host computer operative to execute at least one client application, and at least one controller/processor communicably coupled to the plurality of readers and the at least one host computer. The controller/processor is operative to control operation of the plurality of readers, to process the tag data received by the plurality of readers, and to provide the processed tag data to the at least one host computer for use by the at least one client application executing thereon.

RFID tag data acquisition system

A system and method that facilitates the configuration and control of components of an RFID system, taking into account how the RFID system components are associated with one or more physical locations within an environment in which the RFID system is deployed. A user provides information specifying associations between the system components and the physical locations within the environment to obtain visual representations of configuration data generated therefrom with reference to a facility view, an RF coverage view, and a location view of the data. The facility view serves as a reference plane for placement and orientation of antennas associated with RFID readers, location benchmark tags, and the physical locations of interest. After each antenna is placed and oriented on the facility view, an estimate of the size and shape of the RF interrogation zone of each antenna is computed, and representations of the RF interrogation zones are provided on the facility view to obtain the RF coverage view of the data. Next, the user provides information specifying the physical locations of interest to obtain the location view of the data. A composite of the facility view, the coverage view, and the location view is then generated to obtain an enhanced visual understanding of how the system components and the physical locations exist within the system environment, and how the components and locations are associated with one another.
