  • Patent number: 12321805
    Abstract: Systems and methods for radio-frequency identification (RFID) are disclosed where session control tasks are offloaded from an RFID reader to a separate device which can take the form of an RFID transmitter such as a session control broadcaster. Accordingly, the RFID transmitter transmits messages to RFID tags to control which of the tags within range of the RFID transmitter are in a readable state and/or unreadable state. These messages can take the form of session control messages, and these session control messages can be targeted to tags of interest, such as RFID tags that are deemed to be out of place. By offloading the transmission of messages that control the readability of tags to a separate RFID transmitter, the system frees up the RFID reader to spend more time on inventory read operations, which reduces the risk that an RFID tag will stay hidden when it briefly exists in a hot spot.

  • Patent number: 11927935
    Abstract: Industrial production facilities (such as can making factories) may tag with radio frequency near proximity devices their tooling (knockouts, dies, punches, etc) so that the tooling may be instantly located on any particular machine or location in the facility, by known critical characteristics of the tooling, particularly diameter. This is possible because each machine will also have a reader for the tags, and other areas such as inventory shelves, inspection stations, doors, loading docks, shipping departments and even vendors may also have the reading devices. Passive RFID tags and readers may be used for this purpose. The invention may be open to other businesses so inventory may be located across manufacturing systems and/or businesses.

  • Patent number: 11922258
    Abstract: An interactive data system in which a user, scanning a tag such as a QR-code, is directed to a destination (which may be one of a number of different destinations) which is determined by a profile of the user, which profile is established beforehand. Optionally access to a destination is also determined by an access permission which may be granted to the user. In one example a user, scanning a menu of food and beverage offerings, is directed to a choice of food and beverage which is dependent on the user's likes and dislikes, and dietary and similar factors.

  • Patent number: 11868837
    Abstract: The disclosure provides an electronic cigarette with NFC anti-counterfeiting code and an anti-counterfeiting method thereof. The electronic cigarette comprises a vaporizer arranged with an insertion portion, and a battery rod arranged with a receiving portion for accommodating the insertion portion. The battery rod comprises a battery, and a control circuit board arranged with a microcontroller and a switching circuit. When the insertion portion is inserted in the receiving portion such that the NFC tag and the NFC tag antenna of the insertion portion are close to the NFC card reader and the NFC card reader antenna of the receiving portion, the NFC card reader automatically reads the anti-counterfeiting code preset in the NFC tag and sends it to the microcontroller for identification. If the anti-counterfeiting code is correct, the microcontroller MCU controls switching on of the switching circuit to allow the electronic cigarette to enter a standby state.

  • Patent number: 11861975
    Abstract: A gaming system that receives a frame of image data captured by a camera at a gaming table, generates a set of images from portions of the frame of image data, and determines whether the set of images meets an input requirement of a neural network model. If the set of images does not meet the input requirement, the gaming system modifies, by an incremental amount, an image property of a subset from the set of images until the set of images meets the input requirement. When the set of images meets the input requirement, the gaming system transmits the set of images as a unit (e.g., as a composite of the set of images) to the neural network model for concurrent analysis.

  • Patent number: 11842243
    Abstract: Radio frequency identification (RFID) systems for use with tires include a stud comprising reactive strap technology including an RFID chip and conductor. The stud is configured so as to be connected to a tire and to provide near field communication. The stud also may be coupled to an antenna structure to provide a far field RFID tag. The stud may unintentionally move with respect to the antenna structure during use, so the antenna structure may be configured to accommodate such movement without a change in the tuning of the RFID tag. A multi-antenna label may be provided to allow for selective coupling of the stud to a particular antenna, with differently configured tires being coupled to different antennas of the same type of multi-antenna label, which allows for the same label configuration to be used with a wider variety of tires.

  • Patent number: 11769938
    Abstract: A high-field emission tolerant RFID tag device that may be secured to a product to be cooked, heated, reheated and/or thawed in a heating apparatus such as, but not limited to, a microwave oven and that does not need to be removed from the product before initiating the heating process. The RFID device is microwave safe and does not damage the product or food item to which it is attached during the microwave process, and may contain data to control the microwave process. The microwave safe RFID tag comprises a split ring (or shield) conductor formed on one side of a substrate (or dielectric), a coil antenna conductor formed on an opposite side of the substrate, and a RFID chip. The split ring conductor capacitively couples to the coil antenna conductor via the dielectric and a gap in the split ring conductor prevents arcing.
