  • Patent number: 8837978
    Abstract: A slide rail assembly includes a fixed rail, a movable rail, and a lever member engageable to the fixed rail. In a state where the movable rail is fully removed from the fixed rail, the lever member locks a ball retainer against sliding movement relative to the fixed rail. In a state where the movable rail is assembled to the fixed rail, the lever member releases the locking of the ball retainer. The lever member includes a pressure receiving portion projectable through a window portion of the ball retainer. During reassembly of the movable rail to the fixed rail, the pressure receiving portion is pressed by a pressing portion of the movable rail, so that the locking of the ball retainer by the lever member is released.

  • Publication number: 20140250232
    Abstract: This disclosure relates to creating a resource and for configuring a resource (314) in cloud computing. A processor receives a source resource identifier of a source resource (304) in a source cloud (302) and sends a request to create a target resource (314) in the target cloud (312). The processor then receives a target resource identifier of the created target resource (314) and stores an association (500) between the target resource identifier (504) and the source resource identifier (502). Using the stored association allows to determine a target resource identifier for a resource identifier and therefore configuration of target resources, where the configuration depends on target resource identifiers.
