Abstract: A service provider protocol adapter servlet listens for service advertising requests. Each protocol is associated with a different servlet that understands the details of the service advertising mechanism unique to that protocol. The service provider protocol adapter servlet then converts the service advertisement from a service protocol into a canonical representation of service advertising and stores the advertisement in an internal registry. A client protocol adapter servlet listens for client lookup requests and looks up a corresponding service provider in the internal registry. As with service provider protocol adapter servlets, a different client protocol adapter servlet handles the details of client lookup for each particular protocol. The client protocol adapter servlet then converts a client request into a canonical representation of the request, which is then used to look up the service required by the client.

Abstract: The present invention is a system and method that acquires and aggregates information to determine users' locations. The goal of the present invention is to allow users to collect and evaluate information from multiple sources, and thus make proper use of all available location information. Location sources for the present invention include mobile electronic devices such as mobile telephones, cell phones, hand-held computers, personal digital assistants, pagers, Global Positioning System (GPS) devices, and other pervasive computing devices. Satellite-based or network-based positioning technologies make it possible to determine the geographic location of these wireless electronic devices and their users (e.g. location-based services for users of mobile telephones use such positioning technologies). Location sources for the present invention also include computer-based models, schedules or calendars that give a person's expected location depending on the date and time.

Abstract: A prioritization system (10) utilizes a number of predefined prioritization schemes and a collection of scheme effecting data (12) by which the various predefined prioritization schemes may be effected. Once a user selects a prioritization scheme from the number of available schemes, the prioritization scheme is preferably stored for use in later requested synchronization or sync sessions. When the user requests a sync session to synchronize data at a client device (44, 45, 46) with data stored at another designated device, the prioritization system applies the user's selected prioritization scheme along with the required scheme effecting data and any other necessary parameters to produce a prioritized data set. The data at the client device (44, 45, 46) may then be synchronized to the highest priority data as indicated by the prioritized data set.

Abstract: A method and computer program is provided whereby a personal digital assistant or personal palm-type device of very limited RAM capacity can make available sufficient RAM capacity to store a complete global software distribution package so that the appropriate software or software upgrade may be installed into the device from the global package. The method includes the steps of: first deleting from the personal palm-type device RAM all application programs other than application programs required to support the device operating system to receive the global software distribution package and loading the received global software distribution package into the now available device RAM. Then, the software from the global package needed to make the distribution or upgrade of the device is loaded from the global distribution package into the device programmable ROM where all of the device software is permanently stored.
