  • Patent number: 10054750
    Abstract: A rail structure for optical fiber cassette is adapted to be assembled on a board member of a fiber box. The first engaging structure and the second engaging structure at two ends of the rail body are movably engaged with the first buckling structure and the second buckling structure. Hence, the user may detach one of the rail structures from the board member, so that the distance between the rest two of the rail structures goes wider, and the user can assemble another optical fiber cassette between the two rail structures, and the type and the size of the optical fiber cassette may be different from the detached one. Hence, the rail structure has wide applicability to allow the user to change the optical fiber cassette with different types and specifications conveniently and quickly.

  • Patent number: 9972885
    Abstract: A long-distance radio frequency electronic identification tire structure is provided. When the production of the tire is completed and an electronic tag reading device is used for identification, an RFID chip of an ultra high frequency electronic tag of a main tire body receives and sends an electromagnetic wave signal generated by a far-field copper film antenna and the electronic tag reading device. The frequency band and the bandwidth of the electromagnetic wave signal are adjusted by a frequency band/bandwidth adjustment portion, and first and second field effect adjustment grooves of first and second field effect adjustment portions are configured to adjust the field effect when a tire bead bundle and a steel belt layer reflect the electromagnetic wave signal, so that the electronic tag reading device can read the identification code of the ultra high frequency electronic tag at a wide angle and a long distance.
