The conveyance mechanism conveys a paper on which a a plurality of s are attached with a RFID tag are arranged. The radio wave shielding mechanism includes an opening moving in synchronization with each RFID tag arranged on the paper conveyed by the conveyance mechanism. The antenna receives and transmits a radio wave for communication via the opening while the opening moves in synchronization with the RFID tag. The reader/writer communicates with the RFID tag of the paper conveyed by the conveyance mechanism via the antenna.

A method and system for identification of an item is provided, wherein the system includes a conveyor belt, a positioning device and a reader operable to receive at least one reading at at least one first antenna from at least one tag attached to the item, the first antenna being adapted to be arranged at a read point along the conveyor belt, wherein the positioning device is configured to retrieve a first position of the item at a first time instant before the first antenna and a second position of the item at a second time instant after the first antenna, the first and second time instants defining a time window, wherein the reader is configured to extract from each reading retrieved by the first antenna a measurement (6) of the phase of the signal transmitted by the tag (5) and perform a data processing of the phase measurements whereby the identification of the item (2) is accomplished.

A system to monitor the movement of a plurality of containers including at least one terminal having a photographic device. Each container includes an identification code. The first terminal extracts and decodes the identification code of each container before sending the photograph of that container to a database. A flash connected to the photographic device is triggered during photographing of the container. A controller, including a microcontroller, controls the system and the database. At least one photograph is processed by a processing unit to identify the identification code of each container and to generate a list of the recognized identification codes. A display screen and a trigger to activate the photographing of the containers. The system triggers the photographing during the movement of the container support by a movement element.

A tag reader includes: a phase calculation section that sequentially calculates a phase of a reception wave; a phase difference calculation section that calculates a phase difference as a difference of phases calculated at two time points; and a tag angle calculation section that calculates a tag angle between a straight line connecting an antenna and the wireless tag and a line on which the wireless tag is moving. The phase difference calculation section calculates two values of the phase difference. The tag angle calculation section calculates a first tag angle and a second tag angle. The tag reader comprises a tag distance calculation section that calculates an antenna-tag minimum distance as a minimum distance from the line to the antenna.

A wireless sensor system includes a sensor tag configured to include a radio frequency tag and a communication device configured to wirelessly communicate with one or more sensor tags. Each of the sensor tags is configured to receive a measurement signal from one or more sensor circuits and stores identification information capable of being distinguished from other sensor tags. The communication device includes a transmission means configured to transmit a command signal to the one or more sensor tags and the command signal includes designation information for designating a sensor target serving as an object. Each of the sensor tags generates measurement data on the basis of the measurement signal if the designation information included in the command signal received from the communication device matches its own stored identification information and starts transmission of a response signal including the generated measurement data when a predetermined response start condition is satisfied.

A read chamber device is disclosed for use within a radio frequency identification (RFID) scanning enclosure which provides a means of reading a plurality of cartons moving through the enclosure via a conveyor belt. The enclosure is positioned over a section of the conveyor belt, such that the plurality of cartons on the conveyor belt pass directly through the enclosure. The read chamber device is positioned centrally to the enclosure and projects a read zone via an antenna positioned in-line with the flow of the conveyor which allows the read chamber to read a large variety of inlays without changing the configuration settings of the device. The RFID scanning enclosure also utilizes dynamic power indexing (DPI) to combine parameter inputs to create a smarter reader that can anticipate changes. The reader is then manipulated in real-time to adapt to the needs of each carton and the tunnel scanning environment.

A reader/writer apparatus includes a roller to transport a sheet along a transport path. The sheet can labels disposed thereon spaced from each other. Each label includes a wireless tag, such as an RFID tag. A wireless tag reader has an antenna disposed on the transport path and reads identification data from wireless tags when the sheet is being transported. A processor operates to store the identification data read by wireless tag reader in association with a signal intensity of a response signal from the wireless tag and a position of the sheet on the transport path at the time of the reading of the wireless tag. A position of the sheet on the transport path for each wireless tag can be specified for writing data into the wireless tags based on peak signal intensity associated with identification data.
