Abstract:

A method of manufacturing a fuel rail for use in a fuel delivery system, such as for an engine in a vehicle, includes the initial hydroforming step to deform a central portion of a workpiece to have one or more outwardly extending node portions, followed by a subsequent hydroforming step to deform one or more end portions of the workpiece to have additional outwardly extending node portions. To do this, a pair of pressure feed pistons are disposed within the interior of the workpiece and have head portions that sealingly engage the inner surface of the workpiece so as to define a pressure chamber therein. Pressurized fluid is introduced into the pressure chamber so as to deform a portion thereof into conformance with the portion of the die cavity located within the pressure chamber. Then, the pressure feed pistons are moved to re-define the pressure chamber within the workpiece. Pressurized fluid is again introduced into the enlarged pressure chamber so as to deform other portions of the workpiece.

Abstract:

The invention, in various embodiments, provides systems and methods directed to tiered delivery of content to viewers. At each tier of the delivery process, content providers and/or authors may modify and/or customize a portion of the content based, at least in part, on tags associated with the content and user profiles of the viewers. In particular, the invention includes a method for providing content over a network from a provider to a plurality of user groups, including a first user group and a second user group, comprising managing and publishing the content, from the provider, being provided to the first user group, receiving and managing, by at least one member of the first user group, the published content, identifying, by at least one member of the first user group, a second user group for receiving the content, the second user group being different from the first user group; accessing, by at least one member of the second user group, the content; and tagging, by at least one of the provider and one member of the first user group, one or more portions of the content with one or more tags, each tag being associated with at least one portion of the content.
