An information processing device according to the present technology includes a transmission processing unit that performs processing for transmitting device state information relating to a selected item to an external device of a request source, in response to a request for the device state information relating to the selected item that has been made by the external device, by using code information indicating the selected item, the selected item being an item that has been selected by a user for the device state information indicating a state of a device.

In a printing device, a supply portion is configured to convey a tape in its longitudinal direction. The tape includes: a plurality of labels arranged continuously in the longitudinal direction; and a plurality of storage elements provided on respective ones of the plurality of labels. A first storage element is provided on a first label and configured to store first authentication data. The second storage element is provided on a second label and configured to store second authentication data. A printing portion is configured to print on the plurality of labels. A controller is configured to perform: reading the first authentication data from the first storage element and the second authentication data from the second storage element by a reading portion; and determining whether the first authentication data is correlated to the second authentication data to meet an authentication condition.

Systems and methods for determining radio-frequency identification (RFID) tag proximity groups are provided. The method includes receiving RFID tag readings from multiple RFID tags. The method includes determining signal strengths of the RFID tag readings. The method includes determining pairs of RFID tags based on the RFID tag readings. The method also includes implementing a twin recurrent neural network (RNN) to determine proximity groups of RFID tags based on distance similarity over time between each of the pairs of the RFID tags.

A chipless RFID tag can be scanned with high accuracy and robustness. A tag reader includes: a processing part configured to output information calculated from an emergent wave having an incident wave, as a radio wave irradiated to a tag (an object to be identified) emerged by way of the tag; and a determining part configured to identify attributes of the tag, using the information.

An agricultural data collection framework is provided in a system and method for tracking and managing livestock, and for analyzing animal conditions such as health, growth, nutrition, and behavior. The framework uses ultra-high frequency interrogation of RFID tags to collect individual animal data across multiple geographical locations, and incorporates artificial intelligence techniques to develop machine learning base models for statistical process controls around each animal for evaluating the animal condition. The framework provides a determination of normality at an individual animal basis or for a specific location, and generates alerts, predictions, and a targeted processing or application schedule for prioritizing and delivering resources when intervention is needed.

A portable tracking device including a substantially rectangular base unit. A display screen, a video camera, a keypad, a pair of lights, an activation control, a video control, a bar code scanner, and a camera control are disposed on the base unit. The pair of lights includes a first light and a second light. The bar code scanner is configured to scan the barcode of each of a plurality of tags. The first light of the pair of lights is configured to activate when a user scans the barcode of one of the plurality of tags a first time. The first light of the pair of lights is configured to deactivate and the second light of the pair of lights is configured to simultaneously activate when the user scans the barcode of one of the plurality of tags a second time.

A marker for locating and identify assets which includes an ultra-high frequency (UHF) radio frequency identification (RFID) tag optimized for use below ground and able to more effectively communicate with a RFID reader through a lossy medium such as soil and air. The markers include a reflector which is sized relatively larger than the tag to help focus the forward pattern of the tag more tightly in a forward direction normal to the spiral surface. In addition, the tag includes a chip configured for the soil in which it is to be buried, and an antenna polarized to match the polarization of an RFID reader antenna that is part of a system that includes the marker and reader.

In an IC tag issuing apparatus including a plurality of row antenna units arranged by facing the IC tags in multiple rows aligned as an IC tag continuous body in each row, respectively, and conducting communication in an electromagnetic induction method with each of the IC tags of the IC tag continuous body by using a plurality of the row antenna units, a plurality of the row antenna units are arranged in a row direction or in a direction along a conveyance direction of the IC tag continuous body, and each of the row antenna units is electromagnetically shielded except the position faced with the IC tags of the IC tag continuous body (by a shield plate and an antenna case).

A refrigerator and a control method. The method includes: in response to one or more doors corresponding to one or more storage compartments of a refrigerator being all detected to be closed, obtaining a first of information; determining, by comparing the first set of information with a second set of information, one or more target tags placed in a first storage compartment of the one or more storage compartments, and determining one or more target placement times corresponding to the one or more target tags according to a current time, wherein the second set of information is an information set generated according to identity information of each RFID tag in the one or more storage compartments obtained in response to that the doors are detected to be closed last time immediately before this closing of the doors.

A high speed tabletop and industrial printer is disclosed with integrated high speed RFID encoding and verification at the same time. The industrial printer simultaneously prints on and electronically encodes/verifies RFID labels, tags, and/or stickers attached to a continuous web. The industrial printer comprises a lighted sensor array for indexing the printing to the RFID tags; and a cutter powered from the industrial printer for cutting the web that the RFID tags are disposed on. The industrial printer comprises two RFID reader/writers that are individually controlled. Specifically, one of the RFID reader/writers comprises the ability to electronically encode the RFID tags while the web is moving; and the second RFID reader/writer uses an additional RFID module and antenna on the printer for verifying the data encoded to the RFID tags.
