Abstract: Generating a sequential semantic representation and a resulting content item sequence or presentation is disclosed. A set of nodes and paths among the nodes are determined. Each node includes a corresponding a set of criteria. The paths define a relationship among the plurality of nodes. Transitional operators that define additional criteria for the nodes, are associated with the paths. Content items that include characteristics that are determined to match the corresponding set of criteria for at least one of the nodes are retrieved.

Abstract: A Secure Virtual Point of Service (SVPOS) that coordinates the authentication, authorization, and identity, settlement, arbitration and non-repudiation for an electronic commercial transaction. For each commercial transaction, both the buyer and merchant authenticate itself to the SVPOS and create two unique transaction encryption keys, one for the buyer and one for the merchant. The merchant uses both encryption keys to encrypt a package that include at least product identification. The merchant and buyer calculate a hash of the package and transmit the calculated hash to the SVPOS for comparison to prevent repudiation. If the calculated hash is identical the buyer receives the merchants encryption key and decrypts the package. Payment is released by the SVPOS if the buyer is satisfied with the package via a Parlay system. If the buyer is not satisfied, said SVPOS performs arbitration between the buyer and merchant to determine if the package is correct.

Abstract: A system and method are provided by which a wireless network service provider is able to provide and maintain a high level of quality of service for terminals in the corresponding network, by overcoming problems that result in a diminished quality of service, including handoff delays as terminals move between cells in a network and the uncertainly as to which cell the individual terminals are moving to as they roam within the network. Providing and maintaining a high level of quality of service in a wireless network includes recording a history of movements of a terminal within the wireless network, analyzing the movements of the terminal within the wireless network to compute a probability distribution of the terminal's target location, and allocating network resources, including bandwidth and priority scheme, to the terminal based on the probability distribution for the terminal.

Abstract: A communication system comprises network elements (103, 105, 107, 109) and user equipments (101), at least some of which comprise a charging proxy (205). The system further comprises a charging server (111) which includes a topic controller (305) for initializing charging topics where each charging topic is associable with charging data. The charging server (111) furthermore comprises functionality for registering proxies as subscribing proxies or publishing proxies (or both) for the different charging topics. A receiver (301, 311) receives charging data messages from charging proxies and validates a first set of charging data belonging to a first charging topic in response to a first set of charging proxies registered as publishing proxies for the first charging topic. A charging data transmitter (313) transmits the first set of charging data to a second set of charging proxies registered as subscribing proxies for the first charging topic.

Abstract: A device comprises a display arrangement which includes a plurality of displays that are movable relative to each other such that a plurality of display configurations can be achieved. Each of the display configurations provides a combined display area which is different for at least two of the display configurations. An application processor is operable to execute a plurality of user applications, each of which can provide a display output. A display driver is arranged to generate an arrangement of display output for the display arrangement from the display output of an application being executed. The display driver sets a display characteristic for the arrangement of display output in response to a characteristic of the executed application and the deployed display configuration. For example, depending on the application being executed and the current display configuration, a size of a display window used for the application can be selected.

Abstract: A cellular communication system comprises a network supporting user equipment over an air interface, the network having a hierarchical cell arrangement with overlay cells and underlay cells. An underlay base station is associated with a subset of registered user equipment. An activation server switches the underlay base station between an inactive mode and an active mode in response to detecting that registered user equipment meets a location criterion. The underlay base station only supports user equipment when in the active mode, e.g., it may only transmit a pilot signal in this mode. Interference and power consumption may be substantially reduced by sending the base station into the inactive mode thereby resulting in increased capacity of the cellular communication system as a whole.
