  • Publication number: 20130081573
    Abstract: A system for classifying tiny insects includes a cultivation tank, a detecting container, a detector, a gathering device, and a control unit. The cultivation tank is connected to the detecting container, so that the hatched tiny insects can enter the detecting area of the detecting container from the cultivation tank. The detector is used for detecting the characteristics of the tiny insects in the detecting area, and then the control unit controls the switching unit of the gathering device to switch the gathering containers for gathering the tiny insects according to the detecting results. The system of the present invention is capable of automatically classifying the tiny insects and then gathering them to different gathering containers according to their characteristics, so as to decrease the man power and time necessary for factitious classification.

  • Publication number: 20130014220
    Abstract: The disclosure provides a method and a system for processing an authenticator relocation request. When detecting that initial authentication, re-authentication or authenticator relocation is being performed for a terminal, a network side refuses a new authenticator relocation request from the terminal. When detecting that no initial authentication, re-authentication or authenticator relocation is being performed for the terminal, the network side accepts the new authenticator relocation request from the terminal. Further, when detecting that the initial authentication, the re-authentication or the authenticator relocation is being performed for the terminal, the network side refuses a new re-authentication request from the terminal. According to the technical solution of the disclosure, the complexity of network element processing is reduced and potential safety hazard is avoided.

  • Publication number: 20120248791
    Abstract: An engaging module is used for engaging a cover to a housing. The housing includes a sliding chute extended along a direction. The engaging module includes a sliding member and a hook. The sliding member is slidable between an opening position and a closing position in the sliding chute. The sliding member includes a latch including a first guiding surface and a second guiding surface. When the cover is engaged to the housing, the sliding member may be moved to the opening position along the direction to make the first guiding surface of the latch push the cover to separate from the housing. When it is desired to engage the cover to the housing, the hook is pushed toward the second guiding surface, the sliding member is moved from the closing position along the direction, and the sliding member is moved toward the closing position so that the latch is engaged to the trough of the hook.
