Abstract: A method for operating a sensor based application includes receiving a context hierarchy for the sensor based application, the context hierarchy comprising a plurality of contexts, wherein each of the contexts is assigned a level of interest and a priority, reading the context hierarchy and discovering at least one sensor associated with each of the plurality of contexts, and reading at least one value of each of the sensors, and applying the values.

Abstract: In a method for decision support, a request for information that is part of a context is received, data is generated in response the request, a knowledge model associated with the context is populated with the data, the knowledge model is populated with real-time data associated with the request, the knowledge model is executed, and a result of the executed knowledge model is output.

Abstract: A sensor registry includes a query dispatcher, a registration dispatcher, and a continuous query engine. The query dispatcher receives a query from a subscriber, searches a sensor database for at least one sensor that satisfies the query, and returns a result set corresponding to the query to the subscriber. The result set includes the at least one sensor. The registration dispatcher receives a message from a requesting sensor in a sensor network, and updates the sensor database based on the message. The continuous query engine receives the query from the query dispatcher, updates the result set corresponding to the query based on the received message, and notifies the subscriber upon determining that a change has been made to the result set.

Abstract: A system for recording media content on different recording devices includes a metadata insertion device configured to annotate advertisement content with metadata, where the advertisement content references a media content, and where the metadata is configured to enable recording of the media content on the different recording devices. The system also includes a program finder server configured to determine the next broadcast of the media content available to the different recording devices and a recording server configured to access information pertaining to the different recording devices and configured to schedule a recording of the media content on one or more of the recording devices based upon data and protocols required by the one or more recording devices.
