    Abstract: An inventory system configured for detecting and counting potentially retained surgical items within a body of a patient includes a signal generator which generates an energizing signal for a first RFID tag affixed to a secure package or the second RFID tag affixed to a surgical item, an antenna operably coupled to the signal generator, a processor, and a memory. The antenna is configured to receive at least one of the first return signal transmitted by at least one of the first RFID tag or the second return signal transmitted by the second RFID tag. The memory includes instructions which when executed by the processor cause the system to energize the first RFID tag, receive from the antenna the first return signal including a first unique identifier, and generate a key based on the first unique identifier and a master private key stored on the memory.

    Abstract: A method for estimating channel parameters includes: sending a paging signal for identifying the tag device; sending training sequence information, receiving first training sequence feedback information during a non-working period of the tag device, receiving, during a working period of the tag device, second training sequence feedback information modulated by the tag device, and estimating the channel parameters of the tag device according to the training sequence feedback information and the second training sequence feedback information. The tag device having at least one antenna of the present disclosure can modulate carrier signals to transmit information, has advantages such as a fast transmission rate, a large amount of transmission data and a strong anti-interference capability, and can adapt to different application scenarios.

    Abstract: A writing device is provided to prevent or substantially reduce an occurrence of inconsistency in a destination even when a specification of an apparatus is changed after packaging. According to one embodiment, the writing device includes a first command processor and a second command processor. The first command processor commands a first wireless tag attached to an apparatus to rewrite specification information that is stored in the first wireless tag and that shows a specification of the apparatus. The second command processor commands a second wireless tag attached to a package of the apparatus to rewrite destination information that is stored in the second wireless tag and that relates to a destination of the apparatus, in response to a command given by the first command processor being executed.

    Abstract: The invention relates to an aerosol-generating device (10) for receiving a mouthpiece (12). The aerosol-generating device comprises a detection element (20) for detecting a type of mouthpiece received by the aerosol-generating device, a controller (24) for controlling an operation parameter of the aerosol-generating device and a heating element configured to heat an aerosol-forming substrate of an aerosol-generating article (28) when the aerosol-generating article is received by the aerosol-generating device. The controller is configured to receive an input indicative of the type of mouthpiece detected by the detection element and configured to control the operation parameter of the aerosol-generating device on basis of the detected type of mouthpiece received by the aerosol-generating device. The operation parameter of the aerosol-generating device comprises a temperature profile of the heating element during heating.
