Abstract: A system for factory installation of software that configures the storage resources in one or more file servers as a “cache.” The factory installation system includes at least one file server coupled to a storage management engine (SME) which is coupled to a library server. A target customer system being loaded with software is coupled to the file servers and library server. The library server will have sufficient storage capacity to maintain all of the software that may be requested by a target customer system. The storage management engine will determine which software programs included on the file server memory have been the least recently used and delete those files, thus causing the remaining files on the server memory to be the most recently used. When a target customer computer is being loaded, a request is first made to the file severs for the desired software. If the desired programs are located on the file servers, then a download to the customer computer is implemented.

Abstract: A system for controlling train movement uses a distributed architecture. Wayside controllers receive signals from individual trains, including position information derived from a navigation system. The wayside controllers interface with a central train control network, and coordinate local train movement including the issuance of incremental authorities.

Abstract: A bed frame having a novel leg structure. The bed frame includes a right angle side rail, and a cross rail pivotally connected to that side rail for swinging movement between a storage position in which the cross rail is oriented parallel to the side rail, and a bed support or use position in which the cross rail is oriented normal to the side rail. The novel leg structure includes, in preferred form, a leg member having a U-shaped cross section at the top end thereof, the leg member being fixed to the cross rail adjacent the cross rail's pivotal connection with the side rail. A latch tab is connected with the leg member's center web by a neck having a width less than the width of the latch tab, the latch tab being spaced above the leg member's top edge. The latch tab, neck and leg member's top edge cooperate to define two slots which open away from one another in generally mirror relation.
