    摘要: In an information appliance system 100, a user device 108 comprises a client platform (200, FIG. 5) that includes a service framework (235, FIG. 5) to discover and connect with a variety of services, both remote and local, transient and persistent, and to disconnect from them when they are no longer of interest or become unavailable. The service framework 235 provides a standard, consistent, simplified way for services to make themselves available and for service-using entities to locate and connect with the services of interest to them. When a service is requested from a remote server, a service frontend (281, FIG. 9) on the client platform attempts to find its corresponding service backend (282, FIG. 9) on a server providing the requested service and, if it finds it, the frontend and backend coalesce in a fully formed service that is made available to a requesting service-using entity. As a result, platform resources and security are maintained. Various methods of operating a service framework are also described.

    摘要: In an information appliance system 100, a user device 108 comprises a client platform (200, FIG. 5) that includes a service framework (235, FIG. 5) to discover and connect with a variety of services, both remote and local, transient and persistent, and to disconnect from them when they are no longer of interest or become unavailable. The service framework 235 provides a standard, consistent, simplified way for services to make themselves available and for service-using entities to locate and connect with the services of interest to them. The service framework 235 comprises service event notification registries (254, 256, FIG. 7) in which service-requesting entities register templates defining the types of services they want to locate and connect with. However, the service framework 235, rather than connecting with any service that matches a desired service type, can further control a remote service lookup operation in accordance with various transport characteristics in the template, such as signal strength, quantity of data to be transferred, range, available bandwidth, communications cost, service location, time of day, vehicular velocity, and so forth. This conserves the platform's memory and bandwidth resources by not connecting with services that would not satisfy a user's request or that would be unduly transitory. Various methods of operating a service framework are also described.

    摘要: An embodiment of the invention includes an information appliance system (100) having an information appliance device (102) with a focus manager (206). Among other things, the focus manager is disposed to manage a plurality of asynchronous entities (214). Focus manager (206) receives an asynchronous request (209), stores it in a queue (250) and assigns it a priority level (252, 254, 256). Based on the priority level (252, 254, 256), an asynchronous entity (214) takes over control of user interface device resources from an entity (210), utilizes the resources, and returns them to the entity (210).
