Abstract: An optical card or disc drive having a card or disc adaptive receiving carrying tray. A compound pivot mechanism engages a spindle hub with a card or disc inserted and carried on the tray. The spindle and hub is supported by a base chassis, which pivots with respect to a main frame. A sub-chassis is pivot connected with the mainframe and elastically coupled with the base chassis. A cam member on the main frame engages the sub-chassis to pivot the sub-chassis coincident with the tray being level positioned or lowered relative to card spindle hub. The sub-chassis in turn pivots the base chassis to engage or disengage the disc with the spindle hub. The movement of the tray also activates a motor and roller combination to receive or eject the card into or from the tray. The tray accommodates card or discs and comprises mechanisms for securing the card or disc while the card disc is retracted into and ejected from the main frame.

The programming model defines relationships between various resource types and methods for each resource type to extract a Web service or another linked resource. The programming model also provides caching capability to store previously extract resources for future requests.

Abstract: An extensible software framework is used for the development and customization of XML based Web service deployment descriptors. The framework may provide for the mapping and synchronization of XML data fragments in the XML files to user interface components, resulting in an interface that can be used for the development and customization of the Web service configuration. This mechanism may allow concurrent read and write accesses to the XML based Web service deployment descriptors. The mechanism may be extensible, providing for the mapping between the user interface and the XML data fragments to be customized. Additional extensibility may come from the ability of the framework to readily accommodate the situation where the complete configuration of the Web service is described in multiple XML files. The resulting editor may present one unified display of all of the information across multiple files.

Abstract: An Ethernet passive optical network (EPON) ring for providing protection against fiber failures. The optical network unit (ONU) is coupled to the ring fiber by a three-port passive optical splitting module that has three two-way optical passages. By the three two-way optical passages, the OUN receives/transmits data from/to the two ends of the optical line termination (OLT) to provide protection while the fiber failure. Moreover, it provides better authorization of users and simpler collision detection by the two-way transmission of the three-port passive optical splitting module to prevent hackers from invading and to reduce collisions.
