Abstract: Embodiments of the invention relate to methods and systems for associating a mobile device to a household. In various embodiments, a plurality of latitude-longitude pairs is received for a mobile device during a time period. The latitude-longitude pairs are organized into a plurality of clusters corresponding to geographic regions visited by the mobile device during the time period. For each cluster, a score is calculated that represents a likelihood that a user of the mobile device resides in a household within the cluster. The cluster with the highest score is identified as being the location of the user's household. The computation is preferably conducted recursively over time periods. The mobile device is then associated with the user's household.

Abstract: A system manages access to a cost-constrained resource. The system includes two or more resource consumers that may request access to the cost-constrained resource. Each of the resource consumers may calculate a respective need value corresponding to an amount of data stored in a buffer of the resource consumer relative to a total amount of data that may be stored in the buffer. A concurrency arbitrator may grant access to the cost-constrained resource to a given resource consumer of the plurality of resource consumers based on need values received by the concurrency arbitrator from the plurality of resource consumers. Additionally, or in the alternative, the concurrency arbitrator may grant access to the cost-constrained resource to a given resource consumer based on an amount of data stored in a buffer of the cost-constrained resource that is to be transferred to the given resource consumer.

Abstract: A system comprises memory, process code, and resource partitioning code, where the code is executable by a processor. The process code may spawn multiple processes that request for access to the memory. The resource partitioning code generates resource partition objects and assigns processes to the resource partition objects. The processes may generate media store objects for storage in the memory. The media store objects may correspond to media storage devices and/or the media files accessed by the media storage devices. Access to the memory for storage of the media store objects of a process is based on parametric rules of the corresponding resource partition object.

Abstract: A system and method for the collection, analysis, utilization, and/or reporting of user preference of content experienced by the user preferably for managing the distribution network of a content delivery environment, managing the selections of content available, reporting user selections of content available, and/or execution of user instructions as presented in the content.

Abstract: A method is provided for selecting a resource from a plurality of potential resources in order to provide a service in response to a service request. The method comprises the following steps. Aging services are determined by estimating which of the resources are likely to become available. One of the aging services is disconnected from its resource. The resource is then used for providing the service in the service request. In accordance with a further aspect of the present invention, an oldest service is determined. The oldest service is defined as the service that is most likely to be disconnected from its resource. The oldest service is disconnected from its resource, which is then used for providing the service in the service request.

Abstract: A method is described for improving bandwidth utilization on point-to-point and point-to-multipoint links, wherein data packets are transmitted across the links in cells. The method includes the following steps. A context is defined comprising a plurality of protocol headers for the data packets. At a transmitter, the protocol headers associated with subsequent data to be transmitted are replaced with a compressed header. At a receiver, the compressed header is used for identifying an associated context. The compressed header is replaced with the plurality of headers in accordance with the associated context. How many of the plurality of protocol headers to be compressed is determined such that header compression achieves a header size reduction equal to or greater than a payload size of the cells, thereby improving bandwidth utilization of the link.

Abstract: A circuit arrangement is provided for connecting a personal computer (PC) to a port of a key telephone system via an adapter circuit which also interfaces a digital key set to the port. The adapter circuit is connected to the computer via an RS-232 single channel data link. The PC is programmed to generate and receive a serial data stream into which are encapsulated messages relating to link control and telephone functionality. The adapter circuit is also programmed to receive and generate the serial data stream. The data rate through the adapter circuit and the telephone system and hence to a remote computer is dependent on the utilization of the attached key set by the user to make a call.
