Systems and methods of establishing IP telephony sessions between enterprises are disclosed. A first enterprise requests an association with a second enterprise. Both enterprises and the second enterprise belong to the same federation. The association request is accepted, to establish an association between the first and second enterprises. In response to the acceptance, a direct routed path is established between the first enterprise and the second enterprise. One of the associated enterprises requests activation of an IP telephony service. If the request to activate references the association, an IP telephony session is established using the direct routed path.

A method of deploying a stent-graft in a curved vessel includes deploying an expandable tip to center a proximal end of the catheter containing a stent-graft in the curved vessel. A sheath is retracted to expose the stent-graft and the stent-graft self-expands into the curved vessel. By centering the catheter containing the stent-graft prior to deployment with the expandable tip, the accuracy of stent graft placement within the curved vessel is improved.

A method and apparatus for performing a diagnostic of a web based client server application. The web based client server application comprising a web application code, a web application framework, a web server, and a web client. The method comprising an act of collecting diagnostic data associated with the execution of the web application code, wherein the method of performing the diagnostic of the web based client server application adapts to a type of the web server. In another embodiment, marking the beginning and/or end of a diagnostic session, during which diagnostic data associated with the execution of the web application code is collected, is performed based on a launch of the web client. In a further embodiment, determining information about the web application code at least partially based on an interaction with the web application framework. In another embodiment, determining a type of the web server and starting the web server at least partially based on the determined type of the web server. In another embodiment, performing a diagnostic including code profiling, code coverage, and/or unit tests.

A segmentation method segments selected objects from other objects within a video image frame. The objects may be of arbitrary configuration and preferably represent distinct image features in a display image. An interior outline is formed within the interior of the object perimeter. The interior outline is expanded automatically to form an exterior outline. Pixels between the interior outline and the exterior outline are classified according to predefined attributes as to whether they are within object interior, thereby to identify automatically a conformed outline that is fitted to the object perimeter.

An oil burner comprising an oil/air jet nozzle has a central oil orifice and an outer air orifice; a chamber for oil connected through a control valve to the central orifice; means for supplying air under pressure through a pressure responsive switch and a control valve to the outer orifice, for atomizing oil from the central orifice; means for supplying combustion air through a conduit around the nozzle; an electrically operated ignition means adjacent the nozzle; means for detecting the absence of ignition; and control means operated by the detecting means and the pressure responsive switch for closing the valves on absence of air under pressure, for actuating the ignition means on the detection of the absence of ignition, and for closing the valves on failure of the ignition means to ignite the oil/gas mixture from the nozzle. The invention includes a space heater comprising a hollow canister having an outer wall and a spaced inner wall defining therebetween an inter-wall passage, and means for blowing space heating air into the passage. In that case, the oil burner is arranged with a conduit bridging the inter-wall passage, whereby the flame of the oil burner is directed into the interior of the inner wall and heats that inner wall and hence the air passing through the passage. The oil burner may also be used in a water heater.

Metal pipes are protected from corrosion by externally coating the pipe with a layer of coal tar and wrapping the pipe with at least one extensible material which is porous to allow the coal tar to pass through to form a layer on the outside. This type of wrap avoids any cracking of the protective materials during the commissioning and operation of the pipe.
