A reader device for attachment to a smart device comprising a display, the reader comprising an antenna, processing and reading circuitry, and a communications module, wherein the antenna, the processing and reading circuitry, the processor and the communications module are coupled to each other, and whereby the antenna encloses said display. When a card is tapped on the display, the antenna receives a signal and transmits the signal to the processing and reading circuitry. The processing and reading circuitry processes the signal to produce data, and the produced data is transmitted to a device external to the reader device by the communications module.

A method and system for communicating estimated blood loss parameters of a patient to a user, the method comprising: receiving data representative of an image, of a fluid receiver; automatically detecting a region within the image associated with a volume of fluid received at the fluid receiver, the volume of fluid including a blood component; calculating an estimated amount of the blood component present in the volume of fluid based upon a color parameter represented in the region, and determining a bias error associated with the estimated amount of the blood component; updating an analysis of an aggregate amount of the blood component and an aggregate bias error associated with blood loss of the patient, based upon the estimated amount of the blood component and the bias error; and providing information from the analysis of the aggregate amount of the blood component and the aggregate bias error, to the user.

A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGO™ RFID backscatter transponders, SEGO™ RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.

An apparatus includes a tape cartridge housing, an RFID chip attached to the tape cartridge housing. The RFID chip includes a tape cartridge ID and tape cartridge information, a time relay operably connected to the RFID chip, and external contact points configured to contact another RFID chip of another tape cartridge within the same tier. A method includes receiving a tape cartridge label read request including a position indicator corresponding to a location of a tape cartridge of interest, moving a tape cartridge gripper to the location indicated by the position indicator, activating a field coil on the tape cartridge gripper to provide power to an RFID chip on a selected tape cartridge, detecting information transmitted by the RFID chip on the selected tape cartridge, determining if the selected tape cartridge is the tape cartridge of interest, and activating a next RFID chip on an adjacent tape cartridge.

Systems and methods for facilitating the sorting of assets to sort locations. In various embodiments, a sort employee scans an asset indicia using a user device, which stores asset data corresponding to the stored asset. As the sort employee nears a sort location (e.g., a delivery vehicle) with the asset and the user device, the user device automatically communicates wirelessly with a sort location receiver to associate the asset data with data indicative of the sort location where the user deposits the asset. In various embodiments, a device may determine whether the user device is proximate the appropriate sort location for the item, and may generate an alert upon a determination that the user device is proximate an incorrect sort location.

A system and method are disclosed for tracking animals, which may include production animals as well as pets. The system and method may comprise a tag system that is attached to an animal that generally has at least a near-field-communication (NFC) tag. The tag system comprises at least an NFC tag and a radio-frequency identification (RFID) tag. For NFC tags, such tags may be read with a portable computing device, such as a mobile telephone running NFC reader application software. The phone may communicate with a communications network and ultimately a computer server in order to relay information received from a respective electronic tag. The electronic tags may be fastened, embedded, or ingested by an animal. The electronic tags may be part of a mechanical coupling. Each mechanical coupling may comprise a different structure depending on the whether the tags are fastened to, embedded in, or ingested by the animal.

An electronic door lock management method and system are provided. The method includes: setting electronic keys, including: acquiring lock ID card information having a first user ID through an induction zone, and binding the first user ID to a door lock; acquiring join-in card information having a second user ID through the induction zone, and confirming that the first user ID is the same as the second user ID; acquiring access card information through the induction zone and acquiring file card information through the induction zone, wherein the access card information comprises an access card ID, and the file card information comprises a file card ID; and setting a binding relationship between the access card ID and the file card ID, and taking the access card ID and the file card ID as the electronic keys.

An agent activated non-metal antenna for an ultra-high frequency (UHF) wireless sensor having a radio frequency identification (RFID) tag in electronic communication with the non-metal antenna, and a wireless data communication integrated circuit (IC), includes a conductive stimuli-responsive hydrogel material configured to be inactive prior to an interaction with an activating agent and active upon the interaction with the activating agent. The antenna is further configured to transmit power to turn on the wireless data communication IC only when the non-metal antenna is active upon interaction with the activating agent.

A store apparatus (10) includes a reading result registration unit (110) that registers a tag reading result including tag recording information acquired by reading a tag provided to an individual product by a reading apparatus of a gate and radio wave intensity received from the tag, in association with person determination information about a person who passes through the gate, a purchase product confirmation unit (120) that confirms a purchase product, based on the tag reading result for each person, and a checkout unit (130) that performs checkout processing of the purchase product confirmed by the purchase product confirmation unit (120). When tag recording information related to a same tag is included in both of a first tag reading result related to a first person and a second tag reading result related to a second person who passes through the gate after the first person, the reading result registration unit (110) confirms the first tag reading result, based on magnitude of intensity of a radio wave received from the same tag.
