Abstract: A remote client computer performance/compatibility querying and certification system allows a server to remotely gather performance/capability information from a client computer, such as its processor class or family, display resolution capability, installed software components, peripheral devices, or the type and version of its operating system, and determine whether it is capable of accessing and utilizing an on-line service via a communication network. The performance/capability information is gathered using a querying program downloaded from the server and running on the client computer. The querying program queries the system/component registry of the client computer's operating system using, e.g., one or more application program interface function calls. The gathered performance/capability information is used to, e.g.

Abstract: A remote client computer performance/compatibility querying and certification system allows a server to remotely query a client computer over a communication network to gather performance/capability information of the client computer, e.g., the processor class or family, the type and the version of the operating system, display resolution capability, installed software components, peripheral devices connected to the client computer and/or the like, and determines whether the client computer is capable of accessing and utilizing an on-line service available over the communication network. The performance/capability information is gathered by the use of a querying program downloaded from the server, and running on the client computer. The querying program may query, e.g., through one or more application program interface (API) function calls, the system/component registry of the operating system of the client computer. The gathered performance/capability information may be used, e.g.

Abstract: An emergency command and control system (30) includes a plurality of positioning subsystems (32, 34, 36). Each of the plurality of positioning subsystems (32, 34, 36) has a receiver and a transmitter and transmits positioning signal (38). A wearable tag (40) is capable of receiving the positioning signal (38) from several of the plurality of positioning systems (32, 34, 36) . The wearable tag (40) transmits a tag position. A console (42) contains a computer (44) and a receiver capable of receiving the tag position.
