  • Patent number: 10075559
    Abstract: A server configuration management system is disclosed. The system comprises a script database storing a plurality of audit policies, a plurality of servers that each comprises an agent that executes at least a portion of one of the plurality of audit policies, and a configuration management server communicatively coupled to the script database and each agent. The configuration management server sends an audit script to a plurality of agents executing on a plurality of non-production servers of a common device group in a non-production environment, receives audit results from the plurality of agents, sends a remediate script to corresponding agents executing on non-compliant non-production servers, and responsive to a non-production server malfunctioning as a result of execution of the remediate script, creates, via a user interface, and implements an exception for a production server in the common device group in a production environment that corresponds to the non-production server.

  • Patent number: 8935024
    Abstract: According to one implementation of an engine system, a power device is selectively actuated to provide energy to a storage device. Energy from the storage device is selectively provided to a boost assist device to supplement the normal energy supply to a boost device and enable an increased power output of the engine in at least certain engine or vehicle operating conditions. In one form, the power device may be a source of electrical energy and the storage device is capable of storing an electrical charge. In another form, the power device is a fluid pump and the storage device is capable of storing pressurized fluid. Various methods may be employed to control operation of the power device and energy storage in the storage device.

  • Publication number: 20130270352
    Abstract: A system for supplying supplemental heat to a vehicle, particularly a vehicle with a diesel engine. A driven viscous plate with different viscous clutch faces on either side is provided between the engine and the coolant pump. One side clutches to the engine structure (ground) to generate heat, and the other side clutches to the coolant pump to vary the pump drive. The two sides are controlled by a valve operated by signals from the engine computer. The valve varies the supply of viscous fluid from a common reservoir independently to both sides of the driven viscous plate. The signal from the engine control unit is based on the instantaneous desired supplemental heat and coolant flow. In another embodiment, two separate viscous clutches are utilized and positioned on opposite sides of the coolant pump.
