Abstract: A user interface presented on a local display eases user discrimination between multiple remote displays connected to a remotely controlled computer, thereby easing selection of remote display(s) for remote viewing on the local display. The user interface can incorporate information indicating physical positional orientations of remote displays relative to each other, such as whether one remote display is physically located to the left of another remote display. The icons can additionally illustrate sizes of the remote displays relative to each other. Each remote display can be represented within a particular user interface icon as a rectangle whose size and position relative to the other remote display(s) reflect that remote display's actual physical size and position relative to those other remote display(s). Different icons can show different subsets of active and inactive remote monitors, and can be selected to activate different subsets of remote monitors for presentation on the local display.

Abstract: A superset file browser permits a user to view, in a single display, the superset (i.e., the set union) of file objects from two or more designated file system locations (i.e., directories) on one or more computer systems (local or remote). The uniqueness, or overlap, of file objects between the different designated locations is indicated graphically—typically through the use of different colors and/or icons, alphanumeric labels, popup text, ToolTip text or a combination of these techniques. A superset file browser also permits one-to-many and many-to-many distribution, collection and synchronization operations on the displayed file objects.

Abstract: Contents such as a GUI or application output can be shared in a chat environment. The user can choose to share own contents or request that contents be shared by another user (e.g., a chat partner). It can be possible to control the shared GUI or application from the recipient's location. The shared content can be integrated in content that is transmitted as part of a chat session.

Abstract: Apparatus and methods for providing cellular mobile telecommunication service in accordance with the requirements of the Global Systems for Mobile Communications (GSM) standard. A modular switching system is provided which performs the functions of the mobile switching center plus those of a home location register, authentication center, visitor location register, and equipment identity register. The latter functions are advantageously spread among the modules of the switching system, thus avoiding the getting started cost of expensive dedicated data bases. A wireless global switching module advantageously switches mobile communications control messages among the modules of the system and between the modules and the base station systems, and terminates signaling links between the mobile switching center and the base station systems.
