  • Patent number: 9742686
    Abstract: Mechanisms are provided, in a data processing system comprising a plurality of nodes, each node being a computing device, for controlling access to a critical section of code. These mechanisms send, by a sender node of the data processing system, an access request for requesting access to the critical section of code. The critical section of code is a portion of code that accesses a shared resource. The mechanisms receive, in the sender node, from a plurality of receiver nodes in the data processing system, responses to the access request. Each response in the responses includes a number of active nodes perceived by a corresponding receiver node that transmitted the response. The mechanisms control, by the sender node, access to the critical section of code based on the number of active nodes identified in each of the responses received from the receiver nodes.

  • Patent number: 7069830
    Abstract: Provided is a method for repairing an aperture in a panel in which, a) a plug is inserted in a such aperture to fill same and project above the surface of the panel, b) the plug is adhered in the aperture and c) the plug is flush cut with such surface to repair the panel. Also provided is a tool for flush cutting such projection wherein a blade is mounted across a frame, which blade is mounted at about 90 degrees to the plane of such frame so as to be parallel with the surface of the panel when the frame is mounted upright thereon, to provide clearance for the hand that guides the frame while flush cutting the projection from the panel. Desirably the ends of the saw blade are recessed between smooth feet of the frame so that the blade is elevated slightly above the panel surface, to reduce or avoid scratching thereof during the flush cutting step.

  • Patent number: 5987470
    Abstract: A method of data mining represents related items in a multidimensional space. Distance between items in the multidimensional space corresponds to the extent of relationship between the items. The user can select portions of the space to perceive. The user also can interact with and control the communication of the space, focusing attention on aspects of the space of most interest. The multidimensional spatial representation allows more ready comprehension of the structure of the relationships among the items.

  • Patent number: 4717528
    Abstract: A control system for a nuclear reactor is disclosed. A control rod strategy computer provides for dynamic control of core power distribution in both radial and axial directions and forms the basis for a partial trip capability. Several microprocessor-based computation centers are combined together in a data-sharing network which processors determine local power density, determine the instantaneous differential and integral reactivity worth of each group of control rods, determine and effectuate partial trip for immediate power reduction, determine and provide for uniform core burnup, and effectuate core reactivity changes by directing the movement of groups of four control rods from zero to one hundred percent of travel while minimizing power distribution factors throughout the core. The power control circuitry to move the groups of control rods are bus arranged such that the power circuitry is shared among the groups of control rods.
