  • Patent number: 7693064
    Abstract: Each network node having at least one destination-oriented link toward a directed acyclic graph (DAG) destination can receive a corresponding set of path performance metrics via the destination-oriented link. The set of path performance metrics, initiated by the DAG destination outputting initial link metrics on each of its source-connecting links, identifies aggregate link metrics for a corresponding path to the DAG destination via the corresponding destination-oriented link. The network node outputs a corresponding updated set of path performance metrics on each of its source-connecting links based on the received set of path performance metrics and the corresponding link metric for the corresponding source-connecting link. Hence, each network node in the DAG can assess the performance of each connected path to the DAG destination, and forward a data packet via a selected destination-oriented link based on the corresponding path performance metrics and forwarding policies for the forwarded data packet.

  • Patent number: 7693677
    Abstract: The invention relates to a method having applications for oil exploration and CO2 storage of determining the three-dimensional distribution of the absolute permeability of a heterogeneous sample. The method includes: determining a 3D porosity map of the sample; carrying out a viscous miscible displacement experiment during which the evolution of the differential pressure on either side of the sample is determined; from this evolution, determining a 1D absolute permeability profile along the sample and constructing a first 3D permeability map from the 3D porosity map; estimating a simulated differential pressure by simulating numerically a viscous miscible test from the first permeability map and from the 1D permeability profile; determining the three-dimensional distribution of the absolute permeability of the sample by modifying at least once the first permeability map so as to minimize the difference between the simulated differential pressure and the differential pressure measured over the course of time.

  • Patent number: 7686529
    Abstract: In an embodiment, a two-axis joint that utilizes planar reactions to handle moments applied to the side of the joint thereby allowing the device to remain low profile and compact with minimal intrusion to the mounting surface of the two-axis joint. To handle larger moments, the diameter of the planar member can be increased without increasing the overall height of the joint assembly thereby retaining the low profile thereof. Upper and lower antifriction bearings may be positioned within a housing engage the planar member to reduce rotational friction. The upper and lower bearings and a hub which supports the planar member transfer forces produced by moments applied to the side of the joint so as to spread the forces over the area of the housing.

  • Patent number: 7689541
    Abstract: One embodiment of the present invention sets forth a technique for efficiently performing a radix sort operation on a graphics processing unit (GPU). The radix sort operation is conducted on an input list of data using one or more passes of a series of three processing phases. In each processing phase, thread groups are each associated with one segment of input data. In the first phase, occurrences of each radix symbol are counted and stored in a list of counters. In the second phase, the list of counters is processed by a parallel prefix sum operation to generate a list of offsets. In the third phase, the list of offsets is used to perform re-ordering on the list of data, according to the current radix symbol. To maintain sort stability, the one or more passes proceed from least significant data to most significant data in the sort key.

  • Patent number: 7688793
    Abstract: A wireless sensor node can obtain (102) a wireless sensor node group affiliation pursuant to an affiliation formation process and then subsequently transmit (103) information regarding that wireless sensor node group affiliation. By one approach this affiliation formation process can comprise, at least in part, using wireless sensor node group affiliation information as corresponds to other wireless sensor nodes. Such wireless sensor node group affiliation information as corresponds to other wireless sensor nodes might be received, for example, directly from that other wireless sensor node and/or via an intermediary wireless sensor node that acts to forward such information from the other wireless sensor node.

  • Patent number: 7689665
    Abstract: The present invention extends to methods, systems, and computer program products for dynamically loading scripts. Web pages can include references to script loaders that control the loading of other scripts at a Web browser. A script loader can load scripts in accordance with script loading rules that override the default script loading behavior of the Web browser. Script loading rules can cause scripts to load in a different order than encountered in a Web pager, load in parallel, load in a manner that limits cross-domain requests, etc. Script loading rules are configurable such at that a developer can create customized script loading behavior.
