摘要： Apparatus for reading an RFID tag includes an RF-blocking enclosure having a port and adapted to receive through the port a non-RFID-active object having an RFID tag affixed thereto. An RFID reader has a reader antenna located outside the enclosure. The antenna transmits an RF downlink signal in a particular direction. An RF grating is arranged between the reader antenna and the port so that, after the enclosure receives the object having the tag, the port is located in the transmit direction from the reader antenna, and RF energy transmitted from the reader antenna has a selected linear polarization after passing through the grating.

摘要： An RFID system has an active tag with one antenna inside, and one outside, an RF-blocking enclosure having a port with a selected shortest dimension. The RFID reader is located outside the enclosure and uses a selected RF read frequency range. The RFID tag simultaneously transmits on a plurality of frequencies corresponding to respective wavelengths smaller than the selected shortest dimension, so that a respective beat frequency is defined between two of the frequencies. The beat frequency is within the selected RF uplink frequency range. The tag transmits a first signal at a first one of the plurality of frequencies using the interior antenna and a second signal at a second, different one of the plurality of frequencies using the exterior antenna.

摘要： Apparatus for identifying fluid to be supplied through one of a plurality of RFID-tagged fluid-supply hoses that selectively connect to a movable, RFID-tagged fluid container includes a fluid station including an antenna mount at a fixed location so that a fluid-container location is defined. An RFID reading unit is connected to an antenna on the mount. A controller reads the RFID tag of the movable fluid container positioned in the fluid-container location using the RFID reading unit and reads the RFID tag(s) attached to one or more of the fluid-supply hoses whose respective tag(s) are positioned in the antenna range. The controller then determines which of the plurality of fluid-supply hoses is positioned in the antenna range, so that the fluid in the fluid container is identified as the fluid to be supplied through the determined fluid-supply hose.

摘要： A method of detecting an RFID tag includes transmitting a bait RFID read signal at a bait power level and a simulated response signal at a simulated-response power level. A selected reader frequency is monitored for a selected detection time. A skimmer is determined to be present if a skimmer RFID read signal is detected during that time. If a skimmer is not determined to be present, multiple read signals are transmitted sequentially, each signal at a respective read power level. At least one of the read power levels is lower than the bait power level, at least one of the read power levels is lower than the simulated-response power level, and at least two of the read power levels are different from each other. A selected response frequency for a tag is monitored for a response from an RFID tag.

摘要： A classification of a container is identified using a mobile station including an image capture device and an RFID reader having a reader antenna. The container has two RFID tags affixed thereto at respective, different locations. Each tag has a directional antenna steered in a different direction, so that a reader location is defined in the intersection of the antenna propagation patterns. Using the image capture device, one or more images of the container are captured. A controller determines, using the captured image data, whether the mobile station is in a candidate reader location. When the mobile station is in the candidate reader location, the RFID reader attempts to read both tags. If both tags are read while the mobile station is in the candidate reader location, the controller determines the classification of the container is a classification corresponding to the candidate reader location.

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.
