  • Publication number: 20160099019
    Abstract: Implementations disclosed herein provide a method of reducing the topography at the alignment and overlay marks area during the writer pole photolithography process in order to reduce the wafer scale variation and reduce the writer pole photolithography process rework rate. In one implementation, an intermediate stage of a wafer for writer pole formation is generated by removing a part of at least one metallic writer pole layer on top of an intermediate stage writer pole wafer to form a recovery trench, depositing an optically transparent material on top of the wafer, wherein the thickness of the optically transparent material is higher than a target recovery trench topography, forming a photoresist pattern on top of the optically transparent material over the recovery trench, etching the optically transparent material, and removing the photoresist pattern and at least part of the remaining optically transparent material.

  • Patent number: 8897696
    Abstract: A method uses a relay station to assist processing of requests from user ends. The relay station acquires and monitors channel resource information received from a base station. Upon receiving a request from the UEs via the channel resource, the relay station sends the request received to the base station if it detects no response from the base station to the request. An apparatus uses a relay station to assist processing of requests from UEs. A channel resource acquisition unit acquires channel resource information from the base station. A user monitoring unit monitors the channel resource acquired by the channel resource acquisition unit and for receiving requests sent from the UEs. A base station monitoring unit monitors response from the base station to the requests upon receiving the requests sent from the UEs. A transmitting unit sends the request to the base station when no response from the base station to the request is detected.

  • Publication number: 20140308843
    Abstract: A connector assembly includes a socket connector and a plug connector. The socket connector includes a first top plate and a second top plate. The plug connector includes a first bottom wall and a second bottom wall. The first top plate corresponds to the first bottom wall, and the second top plate corresponds to the second bottom wall. When the connector assembly is correctly assembled, pins extending from the plug connector are allowed to be fully received into inserting slots defined in the socket connector. When the connector assembly is incorrectly assembled, the first top plate abuts against the second bottom wall, blocking the pins from being fully received into the inserting slots.

  • Patent number: 8805276
    Abstract: A mobile communication data transmission method for a cell having one base station and more than one relay station involves switching the relay stations between at least two operating modes of signaling transmission under the control of the base station. A system transmits mobile communication data in a cell having one base station and more than one relay station. When transmitting an uplink signaling or a downlink signaling, the relay stations switch between at least two operating modes under the control of the base station. By using the method, network, relay station, and base station, data transmission in multiple modes can be achieved, so as to achieve a flexible relay scheme.

  • Patent number: 8736422
    Abstract: A method for conducting a passive label query in a radio frequency identification system, wherein a query process conducted by a reader for a group of passive labels comprises a first query and a subsequent query. The link frequency used by a reverse link from the passive label to the reader in the subsequent query is smaller than that the link frequency used by the reverse link in the first query. The method improves the reverse link performance of a passive label radio frequency identification system, and increased the reading success rate of the passive label. A reader is also provided to implement the method.
