  • Patent number: 9787076
    Abstract: A carrier member includes a first section, a second section, and a third section. The first section has a first length. The second section has a second length. The first section, the third section, and the second section connect sequentially and form a U-shaped structure. The first section and the second section have curved sections. The third section has a flat section. When the second section moves relative to the first section, the first section or the second section having the curved section transform into the third section having the flat section and store a resilient recovering force, and the third section having the flat section transforms into the first section or the second section having the curved section for adjusting lengths of the first section and the second section, which prevents a cable disposed on the carrier member from interfering with other mechanism or getting knotted.

  • Patent number: 9741655
    Abstract: An integrated circuit common-mode electromagnetic interference filter incorporating electro-static discharge protection comprising two inductive coils is provided. A pair of primary and secondary spiral inductor coils is disposed corresponding to each other. A dielectric layer is used to separate the primary spiral inductor coil from the secondary spiral inductor coil electrically. Resistivity of a high-resistance substrate is more than 100 ?-cm for supporting the primary spiral inductor coil, the secondary spiral inductor coil and the dielectric layer thereon. The proposed filter structure can be formed in integrated circuit (IC) back-end processes and thus be extraordinarily advantageous of effectively eliminating electromagnetic interferences and having electrostatic protection effect at the same time, while having small footprint.
