  • Patent number: 7688248
    Abstract: A 3D rendered image of a radar-scanned terrain surface is provided from a radar return signal from the surface, wherein the return signal includes data indicative of azimuth, elevation, and range of a radar-illuminated area of the surface. The data are processed for transformation into X, Y, and Z coordinates. The X and Y coordinates corresponding to each illuminated area are triangulated so as to create a mesh of triangles representing the terrain surface, each of the triangles in the mesh being defined by a vertex triplet. 3D imaging information (grey scale shading and/or coloring information) is added to each triangle in the mesh, based on the amplitude of the radar return signal from the coordinates represented by each vertex in the triplet and the value of the Z coordinate at each vertex, so as to form the 3D rendered image.

  • Publication number: 20080071465
    Abstract: Techniques are described for assessing road traffic conditions in various ways based on obtained traffic-related data, such as data samples from vehicles and other mobile data sources traveling on the roads and/or from one or more other sources (such as physical sensors near to or embedded in the roads). The road traffic conditions assessment based on obtained data samples may include various filtering and/or conditioning of the data samples, and various inferences and probabilistic determinations of traffic-related characteristics of interest from the data samples. In some situations, the inferences include repeatedly determining current traffic flow characteristics and/or predicted future traffic flow characteristics for road segments of interest during time periods of interest, such as to determine average traffic speed, traffic volume and/or occupancy, and include weighting various data samples in various ways (e.g., based on a latency of the data samples and/or a source of the data samples).

  • Publication number: 20080071466
    Abstract: Techniques are described for automatically analyzing historical information about road traffic flow in order to generate representative information regarding current or future road traffic flow, and for using such generated representative traffic flow information. Representative traffic flow information may be generated for a variety of types of useful measures of traffic flow, such as for average speed at each of multiple road locations during each of multiple time periods. Generated representative traffic flow information may be used in various ways to assist in travel and for other purposes, such as to determine likely travel times and plan optimal routes. The historical traffic data used to generate the representative traffic flow information may include data readings from physical sensors that are near or embedded in the roads, and/or data samples from vehicles and other mobile data sources traveling on the roads.

  • Publication number: 20070208492
    Abstract: Techniques are described for generating predictions of future traffic conditions at multiple future times, such as by using probabilistic techniques to assess various input data while repeatedly producing future time series predictions for each of numerous road segments (e.g., in a real-time manner based on changing current conditions for a network of roads in a given geographic area). In some situations, one or more predictive Bayesian models and corresponding decision trees are automatically created for use in generating the future traffic condition predictions for each geographic area of interest, such as based on observed historical traffic conditions for those geographic areas. Predicted future traffic condition information may then be used in a variety of ways to assist in travel and for other purposes, such as to plan optimal routes through a network of roads based on predictions about traffic conditions for the roads at multiple future times.

  • Patent number: 6594774
    Abstract: Computer system reliability is improved using various techniques to monitor objects (e.g., processes, threads, DLLs, etc.) executing on the system. Such techniques include active techniques, in which information is continually communicated from the object to the monitor, and passive techniques, in which the object does not need to repeatedly provide information to the monitor. The monitor determines when an object in the computer system has failed, and initiates appropriate recovery action when such a failure is detected.

  • Patent number: 6594723
    Abstract: A computer system includes a Flash or other nonvolatile memory. A program(s) to coordinate data transfers is loaded into a volatile system memory to transfer data from an external device to the Flash memory. The data transferred from the external device to the Flash memory can be transferred to a previously unused portion of the Flash memory, or alternatively can overwrite a previously used portion of the Flash memory. According to one aspect of the invention, the data is transferred from the external device to the volatile system memory and then from the volatile system memory to the Flash memory, allowing additional verification steps to help insure that the data is transferred intact. According to another aspect of the invention, data is copied from the external device to the Flash memory on a portion by portion basis, leaving a set of critical portions to be transferred last.
