An aspect of this invention is a method that includes a computing apparatus estimating geographic locations as a function of time for each of a plurality of sensor nodes. The method further includes estimating a quality of information as a function of time for sensed data to be sensed by the plurality of sensor nodes at the estimated geographic locations; and sending the estimated quality of information as a function of time to one or more applications or consumers of the sensed data.

A method of configuring a logging utility includes generating, by a computer system, at least one message based on a model of logs from at least two software components of a multi-component application and sending, by the computer system, the message to at least one of the two software components for configuring a logging utility of the corresponding software component.

Mechanisms for selecting data providers to provide input data to an application are provided. A desired region and desired quality of information (QoI) function for the desired region are defined. The desired region is a region for which a condition is to be analyzed by the application. One or more provider regions and one or more QoI functions associated with the one or more provider regions are retrieved. A relevancy level between the one or more provider regions and the desired region is calculated based on the desired QoI function for the desired region and the QoI functions associated with the one or more provider regions. One or more data providers for providing input data to the application are selected based on the calculated relevancy level.

Systems and methods provide a selective instrumentation strategy for monitoring the progress of transactions in a distributed computing system. The monitoring of the transactive processing of jobs is considered through a collection of computer operating stages in a distributed system, using limited information. The monitoring is performed by observing log records (or footprints) produced during each stage of processing in the system. The footprints lack unique transaction identifiers resulting in uncertainties in monitoring transaction instances. The processing stages are selective instrumented to reduce monitoring uncertainty under the given constraints such as limited budget for instrumentation cost.

A method of analyzing log data related to a software application includes: selectively collecting data log entries that are related to the application; agnostically categorizing the data log entries; and associating the categories of the data log entries with one or more operational states of a model.

A method for implementing vehicle diagnostics includes: receiving one or more sound signals from a series of sensors distributed and positioned in various operational areas of a vehicle; recording the one or more sound signals in response to a command generated by an operator of the vehicle; storing the one or more sound signals in persistent memory; processing the one or more sound signals; and selecting one or more of the processed sound signals for audio playback in response to a user command; and wherein the audio playback is configured to assist in the diagnosis and prevention of vehicle faults and component defects.

The present invention provides shared communication medium capability to the plethora of computer devices, like the PCCAs, that normally are able to communicate with other devices via dedicated point-to-point links, e.g., via the practically universal RS-232 ports. It allows the sharing of the communication medium in a dynamic fashion depending on the instantaneous traffic demands by the various communicating devices. It further allows the emulation of point-to-point links over the shared communications medium in such a way that applications running on a PCCA use the shared medium transparently. Thus, this invention enables applications designed to operate over a point-to-point connection to operate over the shared medium without any modifications of the applications or the point-to-point devices. It enables the shared medium communications and dynamic communication resource allocation by using a device's I/O ports designed for point-to-point communications with dedicated communication resource allocation.

The present invention provides a method, apparatus and computer product for a mobile device to roam securely and seamlessly from one access point to another access point without disrupting an active PPP connection. The method includes establishing, maintaining, and terminating a PPP connection between a mobile device and a PPP server via an access point, wherein the mobile device is equipped with a serial asynchronous communication interface. The PPP server is attached to a packet switched data network, and the access point is acting as a bridge between the serial communication interface and the packet switched communication interface. Also provided is a method to emulate a direct RS-232 cable connection between a mobile device and another computer located several hops away from the mobile device. It provides a method of keeping the RS-232 cable emulation between the mobile device an another computer system intact despite changes in mobile device's location in the network. It also provides a method of exchanging cookies between peers at the PPP connection establishment time and using them for fast reauthentication. This is a secure method of switching from one PPP proxy to another PPP proxy without disrupting the end to end PPP connection.
摘要:
A method and system for providing on-line services to a user from a services provider over a wireless cellular network. The cellular network is located between the user and the services provider, and a distributed computer system such as the Internet is located between the services provider and the cellular network for transmitting data between the services provide and the cellular network. In one embodiment, the services provider transmits software and operating characteristics over the distributed computer system to the cellular network, and the cellular network installs this software on one or more nodes of the network. When a user connects to the cellular network for services from the service provider, the network operates the software on the one or more nodes in accordance with the operating characteristics, to provide one or more services from this one or more nodes to the user from the service provider.
