A component 10 for use in an alarm system includes a component controller 12 and an offline configuration module 14. The offline configuration module 14 includes a passive RFID tag and is configured to receive and store an indication of at least one configuration parameter wirelessly transmitted to the configuration module. Upon initialisation of the component 10, the component controller 12 operates the component 10 in accordance with one or more protocol determined by the at least one configuration parameter indicated by the indication stored by the offline configuration module 14.

A method of confirming the identity of a person who issued a token to signify eligibility for a privilege. Possession token is confirmed to be by the same person by using sensors in the token which track the movements of the person. A machine learning system is trained to evaluate the sensor data detecting transfer of possession of the token. The state of continuous possession since the token was issued or set to an enabled state is confirmed and the privilege is granted. The method of identity confirmation is used in various contexts such as for to control entry to a location, use of a facility or service. It is also useful to determine continuous possession of a weapon to prevent misuse after the weapon is stolen, dropped or lost. Servers, beacons and outside sources of data or inputs to be measured by the sensor can also be used.

An instrument cassette (100, 200, 300) for handling instruments comprises a body section (101, 201, 301) for holding the instruments and a radio frequency identifier (102, 202, 302) readable from a distance away from the instrument cassette (100, 200, 300). The radio frequency identifier (102, 202, 302) of the instrument cassette (100, 200, 300) facilitates tracing operations, such as for example disinfection, sterilization, reparation, and clinical use, directed to or carried out with a set of instruments handled with the aid of the instrument cassette (100, 200, 300). The instruments can be for example medical and/or dental hand instruments.

Systems and methods for controlling electronic shelf labels are disclosed. Product data identifying at least one product and a price of the at least one product and layout data of a physical environment including locations of one or more shelves, a respective shelf location of the at least one product, and coordinates of a plurality of electronic shelf labels is received. Coordinates for a first electronic shelf label associated with the respective shelf location is determined. A first emitter of a plurality of emitters that is capable of communicating with the first electronic shelf label is determined and positioned to direct a signal to the coordinates of the first electronic shelf label to establish a link with only the first electronic shelf label. A portion of the product data is transmitted via the signal, which causes the first electronic shelf label to display the portion of the product data.

An adaptive inventory management system for use in a materials handling facility storing a plurality of items that are each associated with a Radio Frequency Identification (RFID) tag. The management system including a global inventory database subsystem and a RFID interrogator subsystem comprising a plurality of RFID interrogators that are each configured to read the unique identifier of the RFID tag associated with each of the plurality of items that are within a defined boundary of at least one scan zone generated by the respective RFID interrogator and to communicate the unique identifier of the each scanned RFID tag identified within each scan zone of the respective RFID interrogator to the global inventory database subsystem. The management system being selectively configured to effect user desired levels of fidelity and/or resolution with respect to the generated unique identifier of the each scanned RFID tag within a defined space of the materials handling facility.

This disclosure describes a system for associating multiple totes with a single profile so that items placed into any of the multiple totes are identified on a profile item identifier list. For example, if two users located in a materials handling facility are picking items that are to be consolidated or otherwise treated together, each user may select a different tote and move separately through the materials handling facility. As either user picks items and places those items into a corresponding tote, a profile item identifier list is updated to include an item identifier for each picked item.

A location designation RFID tag for use in a storage facility includes an inlay, a first layer disposed on a first side of the inlay and having a first thickness, and a second layer disposed on a second side of the inlay. The first layer has a first thickness and the second layer has a second thickness. The inlay includes substrate, an antenna disposed on the substrate, and an integrated circuit disposed on the substrate. The location designation RFID tag may be easily and non-invasively placed and relocated on a floor of a storage facility in a manner that mitigates, and likely resolves, the issues experienced by known RFID tags when placed on a floor. Utilizing an inlay having a long, thin antenna, reduces the overall thickness of the location designation RFID tag, which allows layers to be disposed on the inlay that include a sufficient thickness to improve durability, mitigate detuning, and allow movable devices to readily pass over the location designation RFID tag.

A barcode-reading device can send barcode images to a remote server for decoding. A decoder on the remote server can process the images and attempt to decode any barcodes in the images. Once the decoder on the remote server has successfully decoded a barcode, the remote server can send the decoded data back to the barcode-reading device and/or to a host computing device that is communicatively coupled to the barcode-reading device. If the barcode-reading device receives the decoded data, the barcode-reading device can forward the decoded data to the host computing device. In some embodiments, a barcode-reading device can send all captured images to the remote server. Alternatively, a barcode-reading device can send only some captured images to the remote server. In some embodiments, a barcode-reading device can be configured to perform one or more preliminary processing operations on an image before sending the image to the remote server.

A method for locating wireless tags is described. A signal including a RoomID generated by a transceiver is received by a wireless tag. The RoomID identifies a room corresponding to the transceiver and the wireless tag receives the signal asynchronously without being synchronized with the transceiver. A tracking packet including the RoomID and an identifier of the wireless tag is broadcasted by the wireless tag. The tracking packet is received by an access point which provides the tracking packet to a localization system that determines a location of the wireless tag based on the RoomID.
