Abstract: A system and method for producing a massive number of diverse program instances so as to deter differential attacks, collusion, and similar hostile actions. Code portions are shown to be defined in various manners, instantiated, and aggregated. The system and method establishes a very large number of program instances that may be deployed. Furthermore, testing is accomplished over a minimal set of instances to provide for high test coverage and high confidence over the fully deployed in stance set without incurring a high penalty.

Abstract: A method of joining two vehicle axle housing components made from the same or dissimilar materials includes providing a first axle housing component, and providing a second axle housing component, where one of the first and second axle housing components is a metallic component made of a metallic material. A portion of one of the first and second axle housing components is positioned within a portion of the other of the axle housing components in an overlapping manner, thereby forming an overlapping portion. A metallic band may be disposed around the overlapping portion. An inductor is positioned around the overlapping portion. The inductor is energized to generate a magnetic field for collapsing at least one of the overlapping portion and the metallic band, thereby securing the first and second axle housing components together.

Abstract: An method for manufacturing an assembly of first and second components, such as an end fitting and a driveshaft tube for use in a vehicular drive train system. Initially, a yoke is provided including a body having a recess provided therein and a pair of yoke arms. The recess defines an inner body portion and an outer body portion in the yoke. A portion of a driveshaft tube inserted within the recess between the inner body portion and the outer body portion. If desired, one or more retaining structures or an adhesive material may be provided on either or both of the driveshaft tube or the yoke. Then, a magnetic pulse forming process is performed to deform the outer body portion of the body of the yoke into engagement with the portion of the driveshaft tube to provide a combined driveshaft tube and yoke assembly.

Abstract: A method of manufacturing a node and of securing a plurality of structural components to the node to form an article, such as a vehicle frame assembly, includes the initial step of extruding a workpiece having a plurality of longitudinally extending passageways formed therethrough. A plurality of interim workpieces can be formed by separating portions of the extruded workpiece into a plurality of discrete sections. If necessary, the interim workpieces can be machined to provide a plurality of nodes. The nodes can be formed or machined to have one or more bores formed therethrough that extend from a first outer surface to a second outer surface. A portion of the structural member is inserted into the bore from the first outer surface of the node, while a magnetic pulse forming/welding inductor is inserted into the bore from the second outer surface of the node. The magnetic pulse forming/welding inductor is then operated to secure the portion of the structural member to the node to form an assembly.
