  • Patent number: 12541663
    Abstract: A method and system for determining a location of a wireless tag. The method comprises: obtaining an image of the wireless tag by a camera of a user device; determining a location of the user device based on location signals received by the user device; determining an orientation of the user device; determining a location of the wireless tag with respect to the user device based on the obtained image and the orientation of the user device; and combining the determined location of the user device with the determined location of the wireless tag with respect to the user device to obtain a final location of the wireless tag.
    Type: Grant

  • Patent number: 12229623
    Abstract: A method for calibrating a value of an environmental condition derived information supplied by a wireless tag comprises: determining a value of an environmental condition impacting the wireless tag based on (i) information supplied by the wireless tag and (ii) a tag calibration model of the computing system; when a difference between the determined value of the environmental condition and a measurement of the environmental condition made by a user device exceeds a prescribed threshold, updating in real time, the tag calibration model, substituting the measurement of the environmental condition made by the user device for the determined value, and supplying in real time, as an output, the substituted measurement of the environmental condition made by the user device as if it was the value of the environmental condition derived from information supplied by the wireless tag.

  • Publication number: 20230214613
    Abstract: The present disclosure provides a system and method for generating RFID labels using automated RFID encoding, and verification of RFID labels post generation. In some aspect, generating RFID labels may be done using a label printer and an easy-to-attach RFID encoder. The RFID encoder may include an RFID controller coupled to a network, one or more antennas, a barcode scanner, and one or more optical detectors. As printed RFID labels pass through the label printer, the RFID encoder receives serialization data on the printed labels, which is translated into encode data by the RFID encoder and mask encoded into the RFID labels.

  • Patent number: 8192605
    Abstract: Embodiments described herein generally relate to methods and apparatus for forming an electrode structure used in an energy storage device. More particularly, embodiments described herein relate to methods and apparatus for characterizing nanomaterials used in forming high capacity electrode structures for energy storage devices. In one embodiment a process for forming an electrode structure for an energy storage device is provided. The process comprises depositing a columnar metal structure over a substrate at a first current density by a diffusion limited deposition process, measuring a capacitance of the columnar metal structure to determine a surface area of the columnar metal structure, and depositing three dimensional porous metal structures over the columnar metal structure at a second current density greater than the first current density.
