摘要:
A hollow airfoil and a method for manufacturing a hollow airfoil is provided. The method includes the steps of: providing a first airfoil portion, which first portion has a wall with an interior surface and an exterior surface, and one or more ribs extending out from the interior surface; providing a second airfoil portion having a wall with an interior surface and an exterior surface; wherein the first airfoil portion and the second airfoil portion have mating geometries in which the one or more ribs extend between the interior surfaces of the walls of the first and second airfoil portion to form at least one internal cavity defined by the interior surface of the first portion wall, one or more of the ribs, and the interior surface of the second portion wall, and wherein the airfoil includes at least one exterior port disposed in one of the first airfoil portion or the second airfoil portion, or is formed between the first and second airfoil portions, which at least one exterior port is in fluid communication with the at least one cavity; disposing a support material within the at least one internal cavity allowing the support material to be in contact with the one or more ribs, which support material is operative to structurally support the one or more ribs; attaching the first and second airfoil portions together; and removing the support material from the at least one internal cavity through the at least one exterior port.

Provided are techniques for identifying an electronic document having at least two document versions to be migrated, copying document version contents and version metadata of each of the at least two document versions into a collection for transmission to a destination electronic repository, and sending the collection using a migration Application Programming Interface (API) call to the destination electronic repository with a single operation.
摘要:
Differential dynamic content delivery including providing a session document for a presentation, wherein the session document includes a session grammar and a session structured document; receiving a presentation control instruction to present a classified structural element of the session document, wherein the classified structural element comprises one or more versions of presentation content; determining whether at least one version of presentation content of the classified structural element exists for a user; identifying alternative display content for the user if no version of presentation content of the classified structural element exists for the user; and presenting the identified alternative display content to the user.
摘要:
A hollow structure, and a method of forming the hollow structure, where the hollow structure includes first and second metal parts, the second metal part having an interior surface and a tapered support member extending from the interior surface. The hollow structure also includes a friction stir welded joint that extends through the first metal part and into the tapered support member.

Methods, systems, and products for displaying a help resource associated with a device on a remote display apparatus are provided. Some embodiments of methods, systems, and products for displaying a help resource associated with a device on a display apparatus include receiving, in a device, a help event created by a user engaging a help button installed on the device. In response to receiving the help event, typical embodiments include retrieving a help resource associated with the device, and creating, in the device, a help message including the help resource. The help resource can be retrieved from data storage on the device, downloaded from a network location, or any other way of retrieving the help resource that will occur those of skill in the art. The help message is typically broadcast to a display apparatus for display to a user.
