Abstract: A disconnect clutch and method of controlling the connection of a parasitic load to an engine disposed on a machine is disclosed. The disconnect clutch may comprise a flywheel assembly, a friction plate and a coupling. The flywheel assembly may include a flywheel having a cavity, a chamber, a piston moveable between a contracted position and an expanded position, a pressure plate, a lever, and a coupling operably connected to the friction plate. The flywheel may include an end plate. The chamber may be defined by the flywheel and the piston. The lever may apply an activation force to the pressure plate when the piston is in the expanded position. The friction plate may be attached to and rotatable with the flywheel assembly when the piston is in the expanded position and generally stationary when the piston is in the contracted position.

Abstract: Initially, a hardware inventory device is provided within the data processing system. UIC that uniquely identifies the data processing system is stored in a non-erasable memory of the hardware inventory device. An encrypted hash generated by combining the UIC and a BIOS hash is stored in the non-erasable memory of the hardware inventory device. In response to a loading of a software program previously installed within a direct access storage device of the data processing system, the following steps are performed: i. the encrypted hash is obtained from the non-erasable memory of the hardware inventory device; ii. the encrypted hash is decrypted; iii. a new hash is generated by using the UIC and a BIOS from the data processing system, and the decrypted hash is compared with the new hash; and iv. the software program loading is allowed to continue when the decrypted hash matches the new hash.
