    摘要: An active RFID tag has an antenna inside RF-blocking enclosure having a port with a selected shortest dimension. An RFID reader located outside the enclosure at a reader position transmits a downlink RF signal through the port as a directional RF signal on a downlink carrier frequency corresponding to a downlink wavelength smaller than the selected shortest dimension. The port is selectively configured so that the directional downlink RF signal can pass through the port in an access mode during a selected access time interval and are attenuated by at least 60 dB in a restricted mode during a selected restricted time interval that does not overlap with the access time interval.

    摘要: Non-RFID-active units in a space are marked by affixing RFID tags. Two tags are affixed to each unit, each tag having a directional antenna. The antennas are oriented to define a per-unit reader location. Units are arranged in the space so the per-unit reader locations at least partially overlap to define a reader location. The units in the space can also be detected by an RFID reader located in the overlapping per-unit reader locations. A controller can compare a received list of tag identities corresponding to units expected to be in the container to the identities of the tags read to determine whether the expected units are in the container and disposed at positions and with orientations that cause the respective per-unit reader locations to at least partially overlap with the reader location.

    摘要: An RFID system includes an RFID reader with a tag antenna located at a reader location. An RFID tag includes a controller and an antenna. An RF-blocking enclosure spaced apart from the RFID reader includes a port having first and second spaced-apart apertures. The enclosure is positioned with respect to the reader location to define a tag-antenna location at which an interference pattern of a downlink signal from the reader passing through the port provides a selected downlink power at the tag-antenna location, and an interference pattern of an uplink signal from the tag passing through the port provides a selected uplink power at the reader location. The tag antenna is located in the enclosure at the tag-antenna location.

    摘要: RFID tags are read using an RFID reader. A non-RFID-active object has two RFID tags affixed thereto at respective, different tag locations. Each tag has a respective directional antenna steered in a respective, different direction. Respective directional propagation patterns are thus defined and a reader location is defined in the intersection of the propagation patterns. An RFID reader with a reader antenna located at the reader location is provided. The RFID reader is activated to read both tags.

    摘要: A method of verifying the identification of fluids to be supplied successively through a fluid-supply hose that selectively connects to successive movable, RFID-tagged fluid containers includes providing an RFID reading unit including an antenna. A sequence of reference container identification codes is received. A container-present indication indicating one of the containers is positioned so that its RFID tag is in the antenna range is received. In response, the RFID tag of that container is read using the RFID reading unit to determine an identification code of the container. A controller automatically verifies the determined container identification code against the first reference identification code in the sequence using a controller. The starting through verifying steps are repeated, using successive values from the sequence in the verifying step, until all values in the sequence have been verified against container identification codes read using the RFID reading unit.
