  • Publication number: 20140189556
    Abstract: The claimed subject matter relates to an architecture that can enhance and/or simplify tactile-based I/O transactions in connection with a user-interface (UI) of limited form factor. In particular, the architecture can monitor a position of a selector object such as an operator's finger relative to a UI display as the selector object hovers or moves above the UI display. Based upon this position, an analogous coordinate in the UI display can be determined, and a portion of the UI display substantially centered at the coordinate can be modified. As one example, the UI display can be modified to increase the magnification scale (e.g., a virtual magnifying glass) of the portion of the display indicated by the selector object.

  • Patent number: 8750132
    Abstract: A method and an apparatus for processing a session request in a network are disclosed. For example, the method receives the session request by a Serving-Call Session Control Function (S-CSCF), and sends a query to a tElephone NUmbering Mapping (ENUM) server for the session request. The method determines if a response is received to the query to the ENUM server, and inserts an indication of a component failure in a header of the session request if the response is not received from the ENUM server, wherein the indication of the component failure indicates a non-responsive ENUM server.
