  • Patent number: 8599173
    Abstract: The claimed subject matter relates to an architecture that can utilize photo-sensors embedded in a substantially transparent layer of a UI display for tracking objects that approach or hover over the UI display. The photo-sensors can be configured to detect light of certain wavelengths (e.g., visible light, infrared light) that are propagated toward the UI display, while ignoring light emanating from the UI display when displaying content. Accordingly, by examining various characteristics of the incoming light such as intensity, the architecture can identify a location of a shadow incident upon the display caused by an approaching or hovering selector object blocking portions of incoming light. Additionally or alternatively, the architecture can identify a location of higher intensity for light emanating from the selector object.

  • Patent number: 8571015
    Abstract: Methods of routing a non-IP multimedia subsystem (IMS) message from a first user terminal that has telecommunications service provided by a first carrier to a second user terminal that has telecommunications service provided by a second carrier are provided. Pursuant to these methods, a first telephone number mapping (ENUM) database is queried to identify an address of a second ENUM database that is operated by the second carrier. The identified address is used to query the second ENUM database. Routing information for the non-IMS message is received from the second ENUM database in response to the query to the second ENUM database. The non-IMS message may then be routed to the second user terminal based on the routing information received from the second ENUM database. Related systems and computer program products are also provided.

  • Publication number: 20130266132
    Abstract: Efficient telephone number mapping (ENUM) based call routing during area code splits is described. An ENUM domain management component can associate an ENUM domain name with multiple records when a numbering plan area code split links an old area code of a telephone number corresponding to the ENUM domain name with a new area code. An ENUM provisioning component can perform permissive dialing of the old and new area code during ENUM based call routing by utilizing the multiple records.
