    摘要: Virtual network interface selection manager in a client-server system, in which client and server are connectable through a plural alternate networks. System includes plural interfaces connectable to server through the plural networks, current interface indicator identifying a current interface through which data is transmitted to and/or received from the server, and prioritized listing of plural interfaces ranked in a descending order. Event detector detects occurrence of an event including time-out condition; successful interface test; and change in the plurality of interfaces, and a tester tests each plural interface in prioritized listing in a ranked order to test whether server is reachable. Marker identifies which of plural interfaces successfully pass the test, and switch switches from current interface to a higher priority interface when the marker identifies a higher priority interface as having successfully passed the test, whereby current interface indicator will identify the higher priority interface as current interface.

    摘要: A network failover apparatus and method for use in a client-server system. The method includes establishing at least a first and further path between a client and a server. The first path connects the server to the client through a first network and a first interface of the client and the further path connects the server to the client through a further network that is separate from the first network and a further interface of the client. The method also includes reaching the server through the first interface, detecting that the server is no longer reachable through the first interface, and identifying the first interface as failed. The method also includes reaching the server through the further interface after the first interface is identified as failed, testing the first interface to determine whether the server is reachable while the server is reachable through the further interface, and reestablishing a connection to the server through the first interface.

    摘要: An integration server system for mapping data objects on a database schema offers a strongly-typed model API, complex constraint management, and association balancing. The integration server system also has improved performance through optimized handling of ordered associations of data object and of string-valued attributes. The integration server system comprises a database schema configured to store a set of data object instances. A metadata model represents a configuration of the set of data object instances in the database schema. A model application programming interface provides a client application with access to the set of data object instances, and a metadata application programming interface provides a client application with access to the set of data object instances via the metadata model.

    摘要: An apparatus for translating movement of a rotating shaft to rotational movement in two dimensions of a lever arm including a first frame and a second frame, a first shaft rotatably connected to the first frame and arranged for rotation about a first axis of rotation, a lever having a fulcrum, wherein the fulcrum is arranged within the second frame and arranged for pivoting about a second axis of rotation, wherein the second axis of rotation is co-planar with the first axis of rotation, wherein the second frame is rotatably connected to the first frame, the second frame arranged for rotation with respect to the first frame about a third axis of rotation, wherein the third axis of rotation is arranged perpendicularly and spaced apart from the first axis of rotation, wherein the first, second, and third axes have single point of intersection.
