Abstract: Methods, systems, and computer-readable media are provided for a processing an application-authentication request originating from a mobile device. In particular, an application-authentication request comprises user information that is analyzed by an authentication server. The authentication server generates a call to a subscription profile server to validate the user information as belonging to a user profile that is in good standing. In response to determining that the application-authentication request is valid, the authentication server generates an authentication cookie that is provided to the mobile device. Accordingly, the authentication cookie is used by the mobile device to access applications, such as premium services.

The dynamic network interfaces application activates a virtual local area network (VLAN) by associating subnet interface information and a virtual local area network tag, wherein the virtual local area network tag is unrelated to and randomly combined with the subnet interface information, and by transmitting the association of the subnet interface information and the virtual local area network tag to a firewall component and to a network access component.

Abstract: A fan-turbine rotor assembly includes one or more turbine ring rotors. Each turbine ring rotor is cast as a single integral annular ring. By forming the turbine as one or more rings, leakage between adjacent blade platforms is minimized which increases engine efficiency. Assembly of the turbine ring rotors to the diffuser ring includes axial installation and radial locking of each turbine ring rotor.

Abstract: A method for cooling components of a gas turbine engine, having first and second sets of components that require cooling, includes removing thermal energy from cooling air, directing the cooling air from which thermal energy has been removed to the first set of components of the gas turbine engine, and transferring thermal energy away from the second set of components of the gas turbine engine using a vaporization cycle of a vapor cooling assembly. Use of the vaporization cycle offsets thermal energy removed from the cooling air.

Abstract: A media player is provided. The media player comprises a communications interface, a memory store containing a plurality of personalized advertisements, and a media playback component. The targeted advertisements are refreshed by receiving updates from the communications interface during some of the intervals when the media player is connected to a network. The targeted advertisements are indexed by a plurality of characteristics, the first characteristic being a creation date of the targeted advertisements. The media playback component is configured to play a media content, wherein the media content is stored separately from the targeted advertisements, and to play one of the targeted advertisements in the memory store selected based on the characteristics of the one of the targeted advertisements.

Abstract: An oil supply system for a gearbox in a gas turbine engine includes a holding container which holds a quantity of oil to be delivered to a pump. The holding container includes a flexible barrier.

Abstract: A processor-implemented method for providing application single sign on leveraging a virtual local area network identifier is provided. The method comprises an authentication server providing a client device access to a network via association with a virtual local area network and a credential. The method also comprises the device invoking an application hosted on an application server and the application server identifying a virtual local area network tag associated with the device. The method also comprises the application server sending a message to the authentication server requesting linkage of the tag with a user identification associated with the device. The method also comprises the authentication server linking the tag with the user identification associated with the device and sending a message to the application server containing the identification.

Abstract: Systems and methods of delegating a proxy node for content delivery to a wireless device are provided. A wireless device authenticates with a proxy node, and the proxy node provides to the wireless device a list of content stored on a first content node. If the wireless device requests a second content stored on a second content node, the second content node sends an attachment request to the proxy node, the proxy node associates the second content node with the proxy node, and the proxy node delivers the second content to the wireless device.

Abstract: A system is provided that comprises a computer system, a database, and an application that, when executed on the computer system, receives a message containing notification that an unauthorized communication from a client device has been attempted, searches the database for policies associated with a network resource invoked by the unauthorized communication, and determines authorization for association with policies permitting the client device access to the network resource. The system terminates the client device association with a first virtual local area network and sends a reply to a virtual local area network access device and a gateway device containing information to one of modify and replace a virtual local area network interface associated with the first virtual local area network on each component to provision a second virtual local area network. The system also activates association with the second virtual local area network providing access to the network resource.

Abstract: A fan-turbine rotor assembly includes a diffuser section (114) which turns and diffuses the airflow from a radial core airflow passage (80) toward an axial airflow direction. Diffuser flow passages communicate with the diffuser passages (144) at a location which reduces separation of the airflow as the airflow is turned from the radial core airflow passage (80) toward an axial airflow direction through airflow aspiration at the potentially turbulent locations.
