  • Patent number: 10958665
    Abstract: Methods and systems for tag-based identification include receiving a set of parameters at a user device from a remote server. A counterfeit-proof identification tag is read using a sensor in the user device using the set of parameters. Features of the counterfeit-proof identification tag are extracted in accordance with a feature extraction function, using a processor, to generate a tag bit sequence. A challenge function is applied to the extracted features to generate a result. The result is transmitted to the remote server to authenticate the counterfeit-proof identification tag. The counterfeit-proof identification tag is authenticated with a tag database at the remote server.

  • Patent number: 10867137
    Abstract: A passive sensor network constituted by a reader (5), wireless energy emitters (2), and fully passive sensors (1) is described. The passive sensors allow continuously the data collection and transfer thereof whenever requested by the reader, via backscatter at a frequency (4), and in parallel the reception of energy from the transmitters (3). Each sensor integrates an antenna, two impedance matching networks, a semiconductor, a microcontroller and one or more sensors that do not require the use of their own power supply or batteries. The reader (remote unit) initiates the communication process. This communication is achieved by sending radio frequency commands recognized by the passive sensors. These sensors, upon receiving the commands from the reader, initiate the back transmission of data according to the received command. The power transmitters are used to allow continuous power supply of the passive sensors.

  • Patent number: 10860819
    Abstract: Techniques are provided to estimate the location of an RFID tag using tag read information, such as a tag read count or a tag read rate, and an opportunity metric, such as an inventory cycle duration, inventory cycle rate, or inventory cycle count. A tag tracking system determines read information for a tag in a zone and an opportunity metric associated with the tag and the zone. The tag tracking system then computes a success rate based on the tag read information and opportunity metric, and uses the success rate to estimate the location of the tag.

  • Patent number: 10849013
    Abstract: A three dimensional digital spectrum modulation spread spectrum technique (DSM-X) that improves channel diversity by providing multiple bands within the available portion of the frequency spectrum increasing the number of available channels. The system also improves the channel immunity through the use of at least three dimensions of pseudo-random data encoding, which adds two levels of pseudo-random frequency allocation to the pseudo-random data encoding used in prior DSM systems. The three dimensions of pseudo-random allocation may include pseudo-random data encoding, pseudo-random frequency pattern allocation among a plurality of bands defined within the assigned frequency spectrum, and pseudo-random frequency sequencing among a plurality of channels defined within each band. Additional levels of pseudo-random encoding may be implemented in direct sequence coding for header data, repeat packet timing, and packet iteration timing.

  • Patent number: 10841894
    Abstract: The present invention is directed to energy-efficient hibernation in indoor wireless localization systems. A tag passively associates with a detection point (DP) and establishes a reveille time. The tag will awaken at the reveille time and send or receive a beacon to or from its associated DP. If the tag is receiving a beacon, it will awaken, receive, phase-lock its clock based on when the beacon was expected and when it was actually received, and return to hibernation. The DP transmits a scattershot of beacons, one for every tag in the system. If the tag is sending a beacon, it will awaken, send its beacon, and return to hibernation. The DP will receive the beacon and adjust its own clock based on the delay between when the beacon was expected and when it was actually received. The tag will broadcast its location to the DP on a set interval.
