Embodiments of the present disclosure relate to methods, devices and computer readable media for adaptive configuration of multistatic harmonic tag backscatter. A network device transmits, to an illuminator for a passive tag, a request for transmitting an activation signal to a passive tag at a primary frequency and a first transmission power. The network device receives, from the illuminator, information about a harmonic frequency of a harmonic of the activation signal back-scattered from the passive tag, a received level of the harmonic and a distance between the illuminator and the passive tag. The network device selects at least one reader for the passive tag. The network device configures the illuminator to transmit the activation signal to the passive tag at the primary frequency. The network device configures the at least one reader to receive the harmonic of the activation signal at the harmonic frequency.

In accordance with an embodiment, a wireless tag communication apparatus transmits a read command designating a first state as a flag state of a wireless tag. The wireless tag communication apparatus acquires identification information returned from a wireless tag whose flag state is the first state. In the wireless tag communication apparatus, a determination unit determines, on the basis of the acquired identification information, whether or not a position of the wireless tag that has returned identification information has been detected, and instructs the wireless tag whose position has been detected to rewrite the flag state to a second state by a wireless communication device.

A system (100) for storing, identifying and localizing supports (20, 21) for tissue samples embedded in paraffin, comprisinga plurality of supports (20, 21), wherein each one is provided with a respective RFID tag (201), said supports (20, 21) being each a histology cassette (20) configured to contain a tissue sample embedded in paraffin, or a slide (21); a plurality of trays (1), wherein each tray (1) is provided with a respective RFID tag (101), and is configured to contain a plurality of said supports (20, 21), ach tray (1) being provided with a plurality of seats (11), each seat (11) being configured to receive a respective support (20, 21) and each support (20, 21) being adapted to be arranged at a respective seat (11); at least one component (3) provided with a plurality of RFID antennas (10, 31), said plurality of RFID antennas (10, 31) comprising an RFID antenna (10) for reading the RFID tag (101) of a tray (1) of said plurality of trays, and RFID antennas (31) for reading the RFID tags (201) of the supports (20, 21); at least one RFID interrogator (4); one or more demultiplexers (5), by means of which the RFID interrogator (4) may be connected to each RFID antenna (10, 31) of said plurality of RFID antennas (10, 31), said one or more demultiplexers (5) being configured to sequentially activate a unique signal transmission line for each RFID antenna (10, 31) of said plurality of RFID antennas (10, 31); an electronic control unit (6), configured to synchronize said one or more demultiplexers (5) and said at least one RFID interrogator (4) with one another, to sequentially read the RFID tags (210) of the supports (20, 21) and the RFID tag (101) of a tray (1) of said plurality of trays by means of one RFID antenna (10, 31) at a time, of said plurality of RFID antennas (10, 31).

A registered lower orbit satellite-powered generative artificial intelligence (AI)-based lost active smart card (ASC) tracking and reporting mechanism. The methods and systems may include detecting a threshold distance between a lost ASC and a user device. The lost ASC may initiate a reporting, may include a microwave communication transceiver, and may be associated with an originating entity. The methods and systems may include determining a threshold time that the lost ASC was located at least the threshold distance from the user device. The methods and systems may include tracking the geolocation of the lost ASC by submitting instructions to the lost ASC, instructing the lost ASC to emit a beeping noise, and reporting lost ASC geocoordinates to the originating entity. The lost ASC may emit the beeping noise in response to receipt of the instructions from a satellite network.
