6594723, Jul 15, 2003

Filed:

Sep 7, 1999

Appl. No.:

09/391134

Inventors:

Craig Chapman - Redmond WA
Hang Li - Redmond WA
Mark M. Moeller - Bellingham WA

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 1200

US Classification:

711103, 711154, 712 37, 713 1, 713 2, 713100

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.

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 1100

US Classification:

714 2, 714 38, 714 48, 714 25

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.

Assignee:

Inrix, Inc. - Kirkland WA

International Classification:

G08G 1/00

US Classification:

701117

Abstract:

Techniques are described for assessing road traffic conditions in various ways based on obtained traffic-related data, such as data samples from road traffic sensors (e. g. , physical sensors that are near or embedded in the roads) and/or from vehicles and other mobile data sources traveling on the roads. The assessment of road traffic conditions based on obtained sensor data readings and/or other 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. Assessing obtained data may further include determining traffic conditions (e. g. , traffic flow and/or average traffic speed) for various portions of a road network in a particular geographic area, based at least in part on obtained data samples.

International Classification:

G06F 19/00

G06G 7/76
G08G 1/00

US Classification:

701117, 701119, 34099513

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.

International Classification:

US Classification:

701118, 701119

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, as well as in some situations data from one or more other sources (such as physical sensors near to or embedded in the roads). The assessment of road traffic conditions 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 from the data samples. In some situations, the inferences based on the data samples includes repeatedly determining traffic flow characteristics for road segments of interest during periods of time, such as to determine traffic volume and/or average occupancy of the road.

International Classification:

G06G 7/76

US Classification:

701117, 701119

Abstract:

Techniques are described for automatically detecting anomalous road traffic conditions and for providing information about the detected anomalies, such as for use in facilitating travel on roads of interest. Anomalous road traffic conditions may be identified using target traffic conditions for a particular road segment at a particular selected time, such as target traffic conditions that reflect actual traffic conditions for a current or past selected time, and/or target traffic conditions that reflect predicted future traffic conditions for a future selected time. Target traffic conditions may be compared to distinct expected road traffic conditions for a road segment at a selected time, with the expected conditions reflecting road traffic conditions that are typical or normal for the road segment at the selected time. Anomalous conditions may be identified based on sufficiently large differences from the expected conditions, and information about the anomalous conditions may be provided in various ways.

International Classification:

G08G 1/00

US Classification:

701117, 701118, 701119, 701210

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.

US Classification:

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, as well as in some situations data from one or more other sources (such as physical sensors near to or embedded in the roads). The assessment of road traffic conditions 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, at least some of the mobile data sources are configured to frequently acquire and store data samples, and to occasionally make multiple such data samples available together for use in the road traffic condition assessment (e. g. , by acquiring a data sample every minute and by transmitting a group of stored data samples every 15 minutes).
