  • Patent number: 8346108
    Abstract: Disclosed herein is an image forming apparatus capable of avoiding positional interference between an electrical potential sensor and a developing device during the installation or separation of the developing device. The positional interference is prevented by moving the electrical potential sensor out of the movement path of the developing device in association with the opening/closing movement a cover for an access opening in the body of the image forming apparatus for the installation/separation of the developing device. A link device connects the cover and the electrical potential sensor to each other so as to cause the movement of the electrical potential sensor in linkage with the opening/closing of the cover. The link device serves as an anti-interference device that prevents the positional interference between the developing device and the electrical potential sensor.

  • Patent number: 8346286
    Abstract: Provided is a paging method in a broadband wireless communication system. In order to provide a paging service to a terminal in a wireless communication system in which a macrocell base station and a femtocell base station coexist, the femtocell base station receives a deregistration request message from the terminal, and checks whether the femtocell base station can provide a paging service to the terminal. When failing to provide a paging service to the terminal, the femtocell base station receives paging service information from a paging controller, includes paging service information in a deregistration confirmation message, and transmits it to the terminal, and the macrocell base station provides a paging service to the terminal.
