Appl. No.:

09/470025

Inventors:

Chen Zhang - San Jose CA
Donald T. Wooton - Hollister CA

Assignee:

Cisco Systems, Inc. - San Jose CA

International Classification:

G06F 1100

US Classification:

714 4, 714 43, 709224

Abstract:

A distributed computer network testing system includes a test controller and at least one test agent. One or more test agents are configured with interpreters configured to execute instructions contained in a test script. When the test begins, the test controller publishes the test script to an event engine that broadcasts the script on the network. Test agents subscribing to the test script receive the script. Script receipt is the event that triggers test script execution by each interpreter on each subscribing test agent. Each test agent sends test results to the test controller that, in turn, sends all results to a test analysis agent. The analysis agent analyzes the test results and produces a test report that is output to the user.

US Classification:

709218

Abstract:

Techniques and mechanisms are provided that allow participants in an electronic messaging conversation (e. g. email or instant message) to retrieve information related to words and phrases in the electronic messaging conversation without leaving the electronic messaging environment. An electronic messaging environment is provided that includes user interface tools that allow a user to (1) select text within the EM conversation, (2) submit the text to an information retrieval service, such as a search engine, and (3) display the results generated by the information retrieval service. To facilitate the selection of relevant text, certain “suggested words” within the conversation may automatically be highlighted by the instant messaging client. Various techniques are provided for customizing which words are suggested, which sources are searched, and which search terms are used.

G06Q 99/00

US Classification:

705050000

Abstract:

A method for instant messaging, comprising: receiving a login request containing information associated with a user; determining, based on the information, whether that user is authorized to use at least one premium service for instant messaging; causing display of a premium instant messaging user interface enabling use of the premium service on a client computer in response to the user is authorized to use the premium service; and causing the same client computer to display a second instant messaging user interface in response to the user is not authorized to use the premium service for instant messaging.

International Classification:

B60H 1/00
B60H 1/32

Abstract:

A thermal management system includes a refrigerant loop, a motor coolant loop, and a battery coolant loop. The refrigerant loop includes a first refrigerant main-line, a second refrigerant main-line, a first refrigerant branch, and a second refrigerant branch. The first refrigerant main-line includes a compressor, the second refrigerant main-line includes a cabin condenser, the first refrigerant branch includes a cabin evaporator, the second refrigerant branch includes a radiator. The first refrigerant main-line and the second refrigerant main-line selectively communicate with one of the first and second refrigerant branches. The battery coolant loop includes a coolant main-line, a first coolant branch connected to the cabin evaporator, a second coolant branch connected to the cabin condenser, and a third coolant branch. The coolant main-line selectively communicates with at least one of the first to third coolant branches. The battery coolant loop connects to the motor coolant loop in series or in parallel.

Abstract:

A vehicle hitching assistance system includes a controller executing an initial alignment process including searching for a trailer within a specified area of image data that is less than a total field of the image data in directions corresponding with both a longitudinal distance between the vehicle and the trailer and a lateral direction perpendicular to the longitudinal distance, presenting an indication to a driver of the vehicle to reposition the vehicle when the trailer is not identified within the specified area, and removing the indication when the trailer is identified within the specified area. The controller further executes an automated backing process upon identifying the trailer within the specified area, including identifying a coupler of the trailer and outputting a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler of the trailer during reversing.

International Classification:

H04L 29/12
H04L 12/741
H04L 12/751

Abstract:

A method is provided in one example embodiment and includes detecting by a first network element at a first data center site a local connection of an endpoint identifier (“EID”), in which the EID was previously locally connected to a second network element at a second data center site and notifying a mapping server of the local connection of the EID to the first network element. The method further includes receiving from the mapping server identifying information for the second network element and communicating with the second network element using the identifying information to obtain service information for traffic associated with the EID. The method may also include applying a service identified by the service information to outgoing traffic from the EID as well as applying a service identified by the service information to incoming traffic for the EID.

International Classification:

G03F 7/20

Abstract:

A method for improving a process model by measuring a feature on a printed design that was constructed based in part on a target design is disclosed. The method includes obtaining a) an image of the printed design from an image capture device and b) contours based on shapes in the image. The method also includes identifying, by a pattern recognition program, patterns on the target design that include the feature and determining coordinates, on the contours, that correspond to the feature. The method further includes improving the process model by at least a) providing a measurement of the feature based on the coordinates and b) calibrating the process model based on a comparison of the measurement with a corresponding feature in the target design.
