Abstract: In a cellular network, a cell phone transmits a continuous voice signal over a voice channel to a server. The cell phone can also generate events, the events including on events and off events. The events can be time-stamped. The events are transmitted as a data signal over a data channel of the network to the server. In the server, only segments of the voice signal that substantially correspond to a particular on event and a following off event are converted by an automated speech recognition engine. The converted signal can be further processed by a dialog manager that generates speech signals for the cell phone in response to the converted signal.

Abstract: A method and system for managing the presentation or display of information items or context are described. In one aspect of the invention, the method comprises the steps of selecting an entity of a context type associated with a first display, determining at least one second display associated with the context of the selected entity; and making available information associated with the selected entity to each of the determined associated at least one second display. In another aspect of the invention, the method further provides for inhibiting the availability of information associated with the selected entity to a selected one of said determined associated second displays when the selected second display is the same as the first display. In still another aspect of the invention, the method provides for inhibiting the display of information associated with the selected entity when the associated second display is the same as the first display.

Abstract: A method and apparatus for specifying the identification and classification of at leat one application having components distributed over selected nodes of a network system is disclosed. The method comprises the steps of creating a first section containing at least one directive for specifying information or initiating at least one external process for discovering characteristics of the application, creating a second section containing at least one directive for specifying information or initiating at least one external process for storing the discovered characteristics, and creating a third section containing at least one directive for specifying information or initiating at least one external process for testing the discovered characteristics.

Abstract: A system includes a single common graphical user interface for a network of home appliances, comprising a communication window and a task window, both of which are connected to the network. A communication window includes agent utterance bubbles associated with a software agent, and user utterance bubbles associated with a user of the appliances. The agent utterance bubbles display agent utterances, and the user utterance bubbles display user utterances to be selected by the user in response to the agent utterances. A task window includes a selection window for selecting tasks and appliances, and an application program interface for a selected task and appliance. A network of home appliances includes several home appliances connected to an appliance controller by a network. The appliance controller includes the single common graphical user interface.

Abstract: A method interfaces a collaborative agent with an interactive application defined by a task model including a plurality of task elements. The collaborative agent and the interactive application are generated from the task model. The interactive application includes a plurality of application elements. Mappings between the plurality of task elements and the plurality of application elements are determined, and an agent interface is generated from these mappings. The agent interface is consistent with the collaborative agent and the interactive application. Then, the agent interface is coupled to the collaborative agent and the interactive application to enable collaboration between the collaborative agent and a user of the interactive application.

Abstract: The present invention relates to a discourse manager which permits effective collaboration between a user and a computer agent. The system operates according to a theory of collaborative discourse between humans, with the computer agent playing the same role as a human collaborator. The present invention does not concern the internal operation of a particular agent, but relates rather to the structures for managing a collaborative discourse between any type of agent and the user. The discourse manager includes a memory in which application-specific recipes are stored and a memory in which the discourse state is stored. Each recipe specifies a set of actions or subtasks which are performed to achieve an objective. The discourse state includes structures to track the agent's and user's current objectives, a selected recipe for each objective, and completed steps in each recipe.

Abstract: A system is provided to automatically control input permission when multi users and/or software agents interact with a single, shared application in a window-based computing environment, and to indicate to all users which user or software agent currently is providing input or seeking input permission. The system operates by providing each user and agent with a specialized cursor icon that is used for displaying input-permission status and for requesting and relinquishing input-permission. Cursors have three modes with distinct appearances indicating whether the corresponding user or agent has, does not have, or desires input permission. Cursors are replicated on all displays, so that all users can at all times easily see who has or desires input permission. Users interact with the input-permission system by moving and clicking their mouse. Software agents achieve the same effects by sending control requests directly to a software interface provided as part of the invention.

Abstract: An optical fiber is hermetically sealed to a metal housing containing an optical device (e.g, a semiconductor junction laser or photodiode) by threading and centering the fiber through a thin walled metal tube, filling the tube with solder (e.g., a cylindrical preform) and allowing it to cool. The solder, upon solidifying and cooling, squeezes against the fiber and forms a hermetic seal. The tube-fiber assembly is inserted through an aperture in the housing wall, the fiber is aligned with the optical device and then the tube is soldered to the wall. The housing is out-gassed and then back-filled with a noncorrosive ambient such as nitrogen. Other aspects of the hermetic package, including a laser mount, are also described.
