Appl. No.:

10/027694

International Classification:

Abstract:

A data replication facility for distributed computing environments. A computer network having a plurality of network nodes utilizes a distributed directory provider service (DPS) having an established master node. The DPS supports a file replication service (FRS). The FRS establishes one of the nodes as originator node which receives new or updated files from one or more user/GUIs and/or from one or more software providers such as a security provider. The originator node in cooperation with the master node establish a backup copy of the new or updated file in the master node. Thereafter, the originator node publishes a File Version Variable (FVV) representation of the new or updated file to other network nodes (slave nodes) which obtain such file from the originator or, if need be, from the backup master node. Object observers are utilized to determine changes to the file version variables thereby triggering the downloading of new or updated files into the network nodes, whereby data file replication is accomplished throughout the network. In addition to avoiding a single point of failure, embodiments of the present invention also are network-topology independent.

International Classification:

B65G 5703

US Classification:

232 433

Abstract:

A device adapted to receive and store all manner of currency, comprising an exterior housing providing security for the currency collected therein, a coin receptacle, a bill receptacle for stacking paper currency in a compact and aligned bundle or stack, means for vertically supporting a received bill upon a minor portion of the supported lateral edge thereof, means for engaging said received bill from an engagement position proximate said supported lateral edge, and means for articulating said bill engagement means whereby to deliver the bill into said bill receptacle.
