Abstract: The invention provides a hot-dip galvanized steel plate with high adhesion between a plating layer and base steel, and belongs to the field of manufacturing hot-dip galvanized steel plates. Atomic concentration ratio Al/Zn of Al and Zn in a Fe-Al intermediate transition layer between a base steel and a plating layer of the hot-dip galvanized steel plate is 0.9-1.2. The plating layer did not have ? phase, but has relatively thin ? phase and little ? phase. The plating layer mostly consists of ? phase, thus obviously improving adhesion, scratch resistance and wear resistance of the plating layer.

Abstract: An apparatus, system and communication method, which is particularly suited for a radio frequency identification system (RFID), wherein a reflection-transmission apparatus is disposed in a radio system and, during a communication process, the reflection and transmission features of reflection-transmission apparatus presented at the radio frequency are changed to introduce a multi-path signal component which changes with time. Consequently, during the communication process, a receiving apparatus receives and combines the multi-path signal component of communication signals and the radio system performs communication by utilizing time diversity effects. The apparatus, system and method provide effective and continued reduction of communication blind spots in the RFID system, thereby improving the overall success rate for the RFID system to read tags and accomplishing a better balance with the overall reading time.

Abstract: An RFID reader/writer including a reader/writer body, antennas and an antenna switching unit is provided. The reader/writer body distributes to each of its own ports a length of sustained time for transmitting a signal.

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.

Abstract: A method of 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.

Abstract: A method and apparatus according to the technique wherein support of a quality of service is provided for transmissions between at least one node (N) and at least one mobile station (MS1) in a multihop communication environment. Support is ensured by checking the quality of service class of each transmission prior to transmission. Once the checking has been performed, depending on the class of the checked transmission a multihop transmission or a direct transmission is selected for the transmission to the at least one mobile station, whereby a transmission having a quality of service class belonging to a first class of quality of service classes is transmitted using the direct transmission, whereas a transmission having a quality of service class belonging to a further class of quality of service classes is transmitted using the multihop transmission.
