Abstract: In general, the techniques of this invention are directed to autonomic management of autonomic management systems. In particular, the embodiments of this invention use a measure, analyze, and respond model to autonomically manage one or more autonomic management systems. By understanding specific state information of these autonomic management systems, embodiments of the invention may achieve target performance for the autonomic management systems through operations monitoring, analyzing current system state against target state, and modifying the configurations or resources of the autonomic management systems.

Abstract: In general, the techniques of this invention are directed to determining whether a component failure in a distributed computing system is genuine. In particular, embodiments of this invention analyze monitoring data from other application nodes in a distributed computing system to determine whether the component failure is genuine. If the component failure is not genuine, the embodiments may adjust a fault tolerance parameter that caused the component failure to be perceived.

Abstract: A surge relief apparatus for sensing, tracking and responding to pressure changes in a flow system. The apparatus includes a fluid storage tank that is in fluid communication with the flow system. The apparatus also includes a control valve that is connected to the fluid storage tank, wherein the control valve compensates for pressure in response to pressure change in the flow system. The control valve also controls the rate of pipeline pressure rise in the flow system. The surge relief apparatus also includes a hydraulic accumulator in fluid communication with the control valve along with a surge relief valve in fluid communication with the accumulator.

Abstract: A computer system includes a pointing device and a data manipulation keypad on opposite sides of a keyboard. The data manipulation keypad may be either a stand alone unit or attached to the keyboard. A user operates the pointing device with one hand to designate data on a display, and then presses keys with the other hand on the data manipulation keypad to expediently perform data manipulation operations, such COPY or DELETE, on the designated data. Each of the keys on the data manipulation keypad generates keyboard equivalent signals for different data manipulation operations.

Abstract: A surge relief apparatus for sensing, tracking and responding to pressure changes in a flow system to prevent damage caused by transient pressure changes in the flow system having one or more conduits with fluid. The surge relief apparatus comprising a transient pressure sensor, a pressure sensor, a regular and a valve. The transient pressure sensor is in communication with an upstream conduit and is responsive only to the fluid in the flow system for sensing transient pressure changes and for generating a first signal continuously proportional to the rate of change of the pressure. The pressure level sensor is in communication with an upstream conduit and is responsive only to the fluid in the flow system for sensing pressure changes in the flow system and for generating a second signal continuously proportional to the pressure level in the system.

Abstract: In a pressure surge relief system wherein a valve opens to relieve the pipeline when line pressure overcomes a pilot chamber gas pressure and including an accumulator which transfers the pressure of the pipeline liquid to the gas in the pilot chamber, the improvement comprising a column of relatively inert fluid which isolates the elastomer components of the accumulator from the possibly corrosive pipeline fluid.
