  • Publication number: 20080076584
    Abstract: A deflection compensation system for automobile drivetrain components is provided, wherein a shaft is able to continue in driving relationship to another shaft or coupler in driven relationship when their respective axes of rotation are misaligned. At least one of the shaft and the coupler is preferably supported independently of the other and provided with crown involute splines, whereby one of the shaft and coupler when out of relative alignment, continues to drive the other without the necessity of adding additional moving parts to the drivetrain component.

  • Publication number: 20070079235
    Abstract: The system, method and program of the invention enables a new DTD to be dynamically created during runtime from a preexisting DTD. A next document is processed and validated according to the new DTD. An interface is provided that enables plug-in providers to provide fragments of DTD information for at least one new element to be added and the name of the element that is to be added to an existing parameter entity. All of the fragments from each plug-in provider are concatenated together and combined with the static header information of the preexisting DTD to form the new DTD.
