US Patent:

7843842, Nov 30, 2010

Filed:

Aug 4, 2006

Appl. No.:

11/462587

Inventors:

Randall P. J. Ethier - Burke VA, US
Rajesh Kumar - Palo Alto CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G01R 31/08

US Classification:

370248, 370252, 379 3201

Abstract:

A method for initiating a remote trace route includes establishing a communication session between a first endpoint and a second endpoint. The method also includes detecting at the first endpoint a quality impairment in a communication sent from the second endpoint. In response to detecting the quality impairment, the method includes sending a request from the first endpoint to the second endpoint for the second endpoint to initiate a trace route from the second endpoint to the first endpoint. Upon receiving the request at the second endpoint, the method includes initiating a trace route from the second endpoint to the first endpoint.

International Classification:

H04M 3/08
H04M 3/22
H04M 1/24

US Classification:

379 3201

Abstract:

A method for adaptive media quality monitoring includes monitoring at least one metric of a call between at least two endpoints and detecting a threshold crossing event via the monitoring of the at least one metric. The method also includes executing a threshold crossing action based on detecting the threshold crossing event. The threshold crossing action comprises monitoring at least one additional metric of the call.

International Classification:

G09B 23/28

US Classification:

434262

Abstract:

A system and method for quantifying clinical skill of a user, comprising: collecting data relating to a surgical task done by a user using a surgical device; comparing the data for the surgical task to other data for another similar surgical task; quantifying the clinical skill of the user based on the comparing of the data for the surgical task to the other data for the other similar surgical task; outputting the clinical skill of the user.

A61B 5/103
A61B 6/00

US Classification:

600424

Abstract:

A visual tracking and annotation system for surgical intervention includes an image acquisition and display system arranged to obtain image streams of a surgical region of interest and of a surgical instrument proximate the surgical region of interest and to display acquired images to a user; a tracking system configured to track the surgical instrument relative to the surgical region of interest; a data storage system in communication with the image acquisition and display system and the tracking system; and a data processing system in communication with the data storage system, the image acquisition and display system and the tracking system. The data processing system is configured to annotate images displayed to the user in response to an input signal from the user.

A61B 3/10
A61B 1/07

US Classification:

600425, 600167

Abstract:

An autofocusing endoscope includes an objective lens, a relay optical system arranged to relay an image between the objective lens and a proximal end of the autofocusing endoscope, an optical fiber arranged with a distal end proximate the objective lens, a light source arranged to couple light into the optical fiber, an optical detection system arranged to receive and detect light from the optical fiber, and a data processor constructed to communicate with the optical detection system while in operation. The data processor is configured to determine a distance of a surface to be imaged through the objective lens and provide instructions for adjusting a focus of the autofocusing endoscope of the surface.
