Abstract: Situational awareness map display information is generated at a location and populated with sensor information accessed via the Internet. The map display information is made available on the Internet. A remote browser-enabled display terminal accesses the map display information via the Internet, and displays the map and sensor information. A memory associated with the remote terminal is preloaded with fade information. At the remote terminal, a location icon is generated at the cursor location under control of a mouse click. The icon is faded at the stored fade rate. The icon may be a segmented circle surrounding the marked location. Fading may be by sequentially deleting one or more segments from the circle.

Abstract: A browser invokes a program from a server. The server responds with a web page and ancillary logic. The browser displays the web page and loads the logic into memory. The ancillary logic includes a command set, a status indicator for each command type, and a set of command type governors. When a command is initiated at the browser, the appropriate governor observes the status, and deletes the command if the status is “not complete” or passes the command for transmission to the server if the status is “completed.” This prevents the transmission of repeated or redundant commands to the server.

Abstract: A method executes inspections on equipment of a system. The method includes providing an equipment inspection location rule group for a piece of equipment in the system, the equipment rule group including one or more equipment inspection location rules about equipment inspection locations and expected values at said inspection locations, and actions to be commanded when sampled values match the expected values; selecting one or more of the equipment inspection location rules in a corresponding rule group, the selection being made according to a predetermined operating sequence of the equipment inspection location rules; determining if the selected one or more equipment inspection location rules has been satisfied; and executing one or more actions corresponding to the selected one or more equipment inspection location rules if the selected one or more equipment inspection location rules have been satisfied.

Abstract: A command and control system uses J2EE compliant format signals to communicate to the track management system. The track management system operates on an application server arrangement including one or more J2EE compliant application servers. The track management system uses Enterprise Java Beans software components, which are allocated among the various CPUs of the computer processing arrangement by the application server arrangement. Thus, commercial off-the-shelf equipment can be used pursuant to commercial standards to obtain the reliability associated with ready allocation of the Enterprise Java Beans among any of the available CPUs or clusters of CPUs.
