Abstract: An optical transceiver device has an optical transceiver component, an O/E conversion substrate and a switch control substrate. The optical transceiver component is connected to the first, second optical fiber network equipments for the transmission of optical signal, respectively. The O/E conversion substrate is electrically connected to an in-line equipment at a first location for transmission of electrical signal, and may convert the received optical signal into the electrical signal or convert the received electrical signal into the optical signal. The switch control substrate is electrically connected with an optical switching switch and is connected with the in-line equipment at a second location to receive a control signal for the optical switch from the in-line equipment such that the optical switching switch operates at an normal mode or an bypass mode to guarantee normal network communication of the first, second optical network equipment.

Abstract: A work system with an automatic OS login function includes a fingerprint mobile disk and a computer device. The fingerprint mobile disk has a fingerprint capturing unit and a storage unit. The computer device electrically connects to the fingerprint mobile disk. The computer device has a built-in OS, a login password setting unit for setting a domain name, a user name, and an OS login password according to the fingerprint information, and a login password key-in unit that acts as an interface for entering the OS. The domain name, the user name, and the OS login password are stored in the storage unit. When the user turns on the computer device and enters the login password key-in unit, the user automatically enters the OS via the login password key-in unit reading the domain name, the user name and the OS login password from the storage unit.

Abstract: A multi-function printer includes a photo module, an output module and a process module. The photo module is used for obtaining at least one image information. The output module is electrically connected with the photo module for outputting the at least one image information obtained by the photo module. The process module is electrically connected with the photo module and the output module for controlling the information process and transition between the photo module, the output module and an external system. The multi-function printer adopts the photo module to replace the scan module of the prior art to obtain the images. Therefore, regardless of the resolution of obtained image, the present invention has a merit of rapidly obtaining the images. Moreover, the photo module also can obtain the images by a three-dimensional method and can be disassembled from the multi-function printer and operated alone as a general digital still camera.
