摘要:
An airfoil is provided having a cross-sectional geometry which includes a first wall, a second wall disposed opposite the first wall, a leading edge, a trailing edge disposed opposite the leading edge, and a first cavity. The first cavity is disposed between the first and second walls, and the leading and trailing edges. The cross-sectional geometry extends between a first and a second end, and the airfoil is formed from discontinuously reinforced aluminum.

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.
