Abstract: A differential gearbox assembly for a turbine engine having a fan shaft and a drive shaft. The differential gearbox assembly includes an epicyclic gear assembly coupling the fan shaft to the drive shaft. The epicyclic gear assembly includes a sun gear, a planet gear constrained by a planet carrier, and a ring gear. The sun gear is coupled to the drive shaft and the planet carrier is coupled to the fan shaft. The sun gear, the planet gear, and the ring gear all rotate about the drive shaft. The differential gearbox assembly includes an electric machine assembly that includes an input coupled to the epicyclic gear assembly. The electric machine assembly provides mechanical power to the fan shaft through the epicyclic gear assembly.

Abstract: The present invention provides a common framework to determine if machines are patched and automatically applies patches as required. It provides an automated tool to assess patch levels and apply patches on several different UNIX machine types. Further, it provides a centralized, consistent method of providing patches to multiple roles within an organization while automatically managing large quantities of machines. It can manage multiple security standards, machine classifications, and patch security levels and be customized to interface with existing asset management tools. It evaluates the most suitable patch to satisfy the minimal patch requirements and is an early warning system that will tell a user when the user's machine will go out of compliance. The tool is composed of two parts: a server component and client component.
