    摘要： Systems and methods to detect cross reads in RFID tags are disclosed. Existing RFID reading mechanisms do not have the provision of detecting cross reads and eliminating the cross reads while performing inventory of an area. As a result, the user will have to manually determine the cross reads from the data and eliminate them. The disclosed method employs a RFID reader that is equipped with a plurality of engines for performing scan on the inventories. The scanned data is processed by a processing unit. In the processing unit, normalization is performed on the scanned data, neighboring assets and spatial location maps are created. The data from the above processes is employed for detecting cross reads during the scan. The identified cross reads are eliminated based on various other parameters obtained by analyzing scanned data.

    摘要： RFID-based inventory management systems are provided for various applications. Such systems include a plurality of RFID-readable products tags, with each product tag being associated with a piece of merchandise and programmed to generate a signal containing information regarding the associated piece of merchandise. Such systems also include an RFID reader capable of sending and receiving signals from the product tags. Such systems further include a processor capable of receiving signals from the RFID reader with information regarding the product tags. The processor compares the information regarding two or more product tags to determine whether they are being moved together as part of a moving group. If the processor determines that there exists a moving group of product tags, it generates an output based at least in part on the signals being sent from the product tags in the moving group.

    摘要： A radio frequency identification (RFID) architecture is described. RFID tags are interrogated by a reader, which may be located in a network of readers. The reader transmits symbols to the tags. Tags respond to the interrogations with symbols that each represent one or more bits of data. An RFID tag includes an antenna pad, a receiver, a state machine, and a modulator. The receiver is coupled to the antenna pad. The receiver receives a symbol from the antenna pad and outputs a received signal. The state machine is configured to determine a response symbol from the received signal and an operating state of the tag. The modulator is coupled to the antenna pad. The modulator is configured to backscatter modulate the received symbol with the response symbol. The modulator is configured to output the backscatter modulated symbol to the antenna pad.
