Abstract: Systems and methods for machining openings of a component are provided. In one exemplary aspect, a laser system includes features for machining an opening into a component, such as a cooling hole for a CMC component of a gas turbine engine. The component can be oriented in a first position and lasered while oriented in the first position to form a portion of the opening. The component is then oriented to a second position and lasered while oriented in the second position to form another portion of the opening. The component is alternated between the first and second positions until the predetermined geometry of the opening is formed. The component is oriented in the first and second positions such that the laser beam can machine the component without clipping areas that are not desired to be machined.

Abstract: Shrouds and shroud segments for gas turbine engines are provided. In one exemplary aspect, a gas turbine engine includes a first rotor blade stage and a second rotor blade stage. The gas turbine engine also includes a shroud formed from a plurality of shroud segments that each have a body and a vane extending from the body. The vane is disposed within the flow path between the first rotor blade stage and the second rotor blade stage to form at least a portion of a nozzle stage. Further, the body of the shroud segment defines an outer wall of the flow path and spans from the first rotor blade stage to the second rotor blade stage. An impingement baffle segment couples the shroud segment with a casing of the gas turbine engine.

Abstract: A user device operated by a user receives a compromise alert indicating a potentially compromised use of first access data associated with a user. The compromise alert enables the user to input a response to the compromise alert, where the response can indicate that the first access data is compromised along with a request to issue new access data for the user. The response is sent to a server computer, which then initiates a process to disable use of the first access data and generate the new access data. The new access data is transmitted to the user device. The user can utilize the new access data to request access to a resource.

Abstract: Embodiments of the invention describe a near real-time account messaging system using the ISO 8583 protocol and 0600 administrative message type for sending configurable notification messages to clients based on defined triggers activated by events, or transactions, occurring on an account. The account can be registered with the account messaging system and with the client system. The client is not a participant within the event causing the notification message to be generated and sent to that client.
