A method for vehicle-loading warehousing asset management based on an ultra-high frequency (UHF) radio frequency identification (RFID) path loss model, which includes the following steps. An electromagnetic wave is emitted by a tag reader. The electromagnetic wave is diffracted, reflected, and scattered when passing through a warehousing vehicle hood, and the electromagnetic wave is emitted and scattered through the ground. A UHF RFID tag attached to a front surface location region of assets receives electromagnetic waves of various paths emitted by the tag reader. The tag reader reads UHF RFID tag information. A transfer function of a tag receiving signal is constructed according to the tag information, and a path loss function during a UHF RFID tag sensing electromagnetic wave process is constructed according to the transfer function. The path loss is calculated according to the constructed path loss function. A location of the UHF RFID tag is obtained.

With a parts supply system in which a plurality of parts boxes is transported by a trolley while the parts boxes are unloaded from the trolley at respectively corresponding part-supply places provided on a parts transport route, progress status of supply of the parts boxes to respective unloading places is determined. Information of RFID tags T1 to T10 respectively applied to a plurality of parts boxes B1 to B10 is read by ID tag reading devices 4A, 4B and 4C respectively mounted on trolleys 21, 22 and 23. Thus, the respective parts boxes B1 to B10 that exist on the trolleys 21, 22 and 23 are identified, and information is generated on the progress status of supply of the respective parts boxes B1 to B10 to the part-supply places. Thus, the progress status of the supply of the parts boxes B1 to B10 to the part-supply places is recognized.

According to an embodiment, a control device for an image forming apparatus includes a controller that acquires reference information corresponding to expected signal strength values from a wireless tag on a sheet moving along a conveyance path and also acquires measured signal strength values for a first wireless tag on a sheet from a wireless tag communication device. The controller calculates a similarity value from the measured signal strength values and the expected signal strength values to determine whether the first wireless tag is on a sheet moving along the conveyance path. The controller controls the wireless tag communication device to write information to the first wireless tag when the calculated similarity value is above a threshold similarity value.

A method for reading ultrahigh frequency RFID (Radio Frequency Identification) tags is provided, wherein: an ultrahigh frequency RFID scanning system includes an ultrahigh frequency RFID reader and an antenna group; antennas are distributed around a scanned object; the RFID tags are in the scanned object; the ultrahigh frequency RFID scanning system continuously scans the scanned object, till no new data is added to a scan set A, and then counting is started; if no new data is added to the scan set A for N consecutive scan cycles, it is considered that the ultrahigh frequency RFID scanning system has read all the RFID tags in the scanned object. The present invention overcomes the problem that neither the setting of “reading time” nor the setting of “number of times of reading” can determine whether the ultrahigh frequency RFID scanning system has actually read all the RFID tags.

A system and method for hands-free stock picking using radio frequency identification (“RFID”) includes a fixed RFID reader configured to interrogate RFID tags associated with inventory that is disposed on shelving, and an RFID barrier that is configured to substantially inhibit interrogation of RFID tags associated with active inventory on the shelving. The RFID reader receives responses from the replenishment inventory on the shelving which are tabulated. When an item is picked from the active inventory and moved away from the RFID barrier, the RFID reader receives an increased number of responses for that item compared to the tabulated inventory. The system then associates the picked item with the associated customer order.

An article conveying equipment includes: a carrying apparatus (1), configured to carry one or more articles to be transported; a communication apparatus (3), configured to learn a height of a receiving end of a transferring apparatus matched with the article conveying equipment; and a height adjusting apparatus (2), when the article conveying equipment approaches the transferring apparatus, the height adjusting apparatus is configured to adjust the height of the carrying apparatus to the height matched with receiving end of the transferring apparatus.

Systems and methods of using multiple read area zones to generate more accurate item-level data are described herein. In some embodiments, the systems and methods involve a local read area in combination with a wide read area. In some embodiments, a local area read device alone, or in combination with a wide area read device, is used to detect the removal or return of a product from a merchandising location or area in retail establishment. In some embodiments, a local area read alone, or in combination with a wide area read device, is used to detect the removal or return of a product from a merchandising location or area in retail establishment by detecting/reading a digital trigger on the product.

A method for reading ultrahigh frequency RFID (Radio Frequency Identification) tags is provided, wherein: an ultrahigh frequency RFID scanning system includes an ultrahigh frequency RFID reader (1) and an antenna group; antennas (2) are distributed around a scanned object (4); the RFID tags are in the scanned object (4); the ultrahigh frequency RFID scanning system continuously scans the scanned object (4), till no new data is added to a scan set A, and then counting is started; if no new data is added to the scan set A for N consecutive scan cycles, it is considered that the ultrahigh frequency RFID scanning system has read all the RFID tags in the scanned object (4). The present invention overcomes the problem that neither the setting of “reading time” nor the setting of “number of times of reading” can determine whether the ultrahigh frequency RFID scanning system has actually read all the RFID tags. Moreover, the reading time and the number of times of reading are dynamically adjusted with the quantity of the RFID tags and the reading difficulty of the RFID tags, which not only ensures the accuracy of reading quantity, but also improves the reading efficiency.

Systems and methods for managing inventory, including one or more devices, such as computers or other terminal devices and/or computer systems, for managing inventory through the supply chain and lifecycle of a product. The system and method may include features for receiving the same or similar information associated with a plurality of products from a manufacturer, a distributor, and/or a consumer or other user, and associating various information, such as product location, quantity, and/or condition information with the products via one or more RFID devices operating at a plurality of frequencies, at any one or more locations, by any one or more devices, during the product lifecycle.

A delivery portal, which may be at a loading dock, includes a sensor configured to detect a pallet, platform or stack of goods as it passes through the portal. A computer is programmed to receive information from the sensor and to identify the pallet based upon the information. The computer is further programmed to compare the identified pallet to a database to determine if the identified pallet should be passing through the portal. For example, the computer determines whether the pallet is being loaded onto the wrong truck or onto the right truck but in the wrong sequence. The sensor for detecting the pallet may be an RFID sensor reading an RFID tag on the pallets. The portal may be a loading dock. The database may indicate a sequence for loading a plurality of pallets including the identified pallet onto a truck at the loading dock.
