Abstract: A fuel delivery system (201) is shown for delivering the hydrogen fuel from a cryogenic storage system to a fuel injection system in a gas turbine engine. The fuel delivery system includes a pump (301), a metering device (302), and a fuel heating system (303,304) for heating the hydrogen fuel to an injection temperature for the fuel injection system.

Abstract: A computer implemented method includes detecting user interaction with mixed reality displayed content in a mixed reality system. User focus is determined as a function of the user interaction based on the user interaction using a spatial intent model. A length of time for extending voice engagement with the mixed reality system is modified based on the determined user focus. Detecting user interaction with the displayed content may include tracking eye movements to determine objects in the displayed content at which the user is looking and determining a context of a user dialog during the voice engagement.

Abstract: The subject matter described herein includes methods, systems, and computer program products for selectively processing or redirecting SCCP messages. According to one method, an SCCP message addressed to an STP and sent route-on-PC-SSN is received at the STP. It is determined whether the SCCP message can be processed locally by the STP. In response to determining that the SCCP message can be processed locally by the STP, the SCCP message is terminated, processed locally, and a response is sent to the message originator. In response to determining that the message cannot be processed locally at the STP, the SCCP message is redirected to a destination.

Abstract: The subject matter described herein includes methods, systems, and computer program products for selective network management in a network having multiple active routes to a common destination that are keyed by different combinations of parameters. According to one aspect, the subject matter described herein includes a method for controlling distribution of network management messages concerning the status of a signaling link by provisioning a routing node with a primary route to a destination and at least one exception route to the destination wherein the primary route and the exception route are keyed by different combinations of signaling message parameters.

Abstract: Methods and systems for identifying and redirecting messages of different SS7 protocol variations are disclosed. A screening function receives SS7 message and identifies candidates for redirection. An SS7 variation identifier/redirection function identifies the SS7 protocol variation of incoming SS7 messages identified as candidates for redirection. The redirection candidates are encapsulated in SCCP messages. The SCCP messages are then forwarded to an application. The SCCP messages preferably include indicators identifying the protocol variations of their payloads. Upon receiving the SCCP messages, the application decodes the payloads using the protocol variation indicator.
