Title: Method for automatic testing of optical fibres in multibranch networks
Inventor: SUINO DIEGO
IPC: H04B10/071
Filed: 2003-02-12
Abstract: The method for automatically testing optical fibres in multi-branch networks implements Optical Time Domain Reflectometry technology (OTDR) in which an optical signal pulse is pumped into a fibre and the respective backscattered signal is periodically analysed to obtain attenuation values according to distance. The method is used to identify the fibre and the position in which attenuation increase of the backscattered signal is found even when the signal is sent upstream of each branch point from which the individual fibres to be tested depart.

Title: Enterprise content delivery network having a central controller for coordinating a set of content servers
Inventor: KLONINGER JOHN J
IPC: H04L29/08
Filed: 2003-05-14
Abstract: An enterprise content delivery network includes two basic components: a set of content servers, and a central controller for providing coordination and control of the content servers. The central controller coordinates the set of distributed servers into a unified system, for example, by providing provisioning, content control, request mapping, monitoring (126) and reporting (146). Content requests may be mapped to optimal content servers by DNS-based mapping (152), or by using a policy engine (120) that takes into consideration such factors as the location of a requesting client machine, the content being requested, asynchronous data from periodic measurements of an enterprise network and state of the streaming media servers, and given capacity reservations on the enterprise links. An ECDN (130) provisioned with the basic components facilitates various customer applications, such as one or more of the following: live, corporate, streaming media (internal and Internet sources) and HTTP (145) content delivery.

Title: Method and device for management of tree data exchange
Inventor: HARTIKAINEN RAUNO
IPC: H04L29/06
Filed: 2002-04-30
Abstract: A management tree or nodes arranged hierarchically tree-like, respectively, is used to manage, contain and map information of a manageable device according to the SyncML DM protocol standard. A management server can request from such a device may the means of a GET command information contained in a certain node of the management tree server. The manageable device responses by transmitting the requested information of the management tree.

Abstract: Devices and methods are directed to improving the gaseous exchange in a lung of an individual having, for instance, chronic obstructive pulmonary disease . More particularly, conduits may be deployed in the lung to maintain collater al openings (or channels) surgically created through airway walls. This tends t o facilitate both the exchange of oxygen ultimately into the blood and decompress hyper-inflated lungs. The conduit includes a radially expandable center section having a first end, a second end, and a passageway extending from the first end to the second end. A control segment may be associated wi th the conduit to limit the degree of radial expansion. The conduit further includes a plurality of deflectable members extending from the ends of the center section. A tissue barrier may coaxially surround the conduit such tha t tissue ingrowth is prevented. The conduits may also include hold-down member s and bioactive coatings that serve to prevent ejection of the conduit as well as prevent narrowing of the passageway due to tissue ingrowth.

Abstract: Systems and methods for providing trading using an eVWAP price in an illiquid market are provided. In an illiquid market there may be little or no actual trades. During a trading period, the eVWAP price is therefore determined from not only trades, but also unmatched bids and offers. The eVWAP price is determined when new information becomes available or at a specified time interval. The final eVWAP price is determined when the sampling period ends. Once the final eVWAP price is determined, the value of the final eVWAP price is published for use as a price to settle a contract.

Abstract: L'invention concerne un procédé de production de corps moulés métalliques très poreux, comprenant les étapes suivantes : une poudre métallique, utilisée comme produit de départ, est mélangée à un substitut ; une ébauche crue est formée par compression à partir de ce mélange ; cette ébauche crue est soumise à un usinage mécanique classique, ledit substitut augmentant de façon avantageuse la stabilité de cette ébauche ; la matière de substitution est séparée thermiquement de cette ébauche crue à l'air, sous vide ou sous gaz protecteur ; ladite ébauche crue est frittée de manière à former le corps moulé puis polie de façon avantageuse. Parmi les matières de substitution appropriées figurent, par exemple, le bicarbonate d'ammonium ou encore la carbamide. L'usinage mécanique avant le frittage permet une production simple, proche du contour final souhaité, même lorsque le corps moulé à produire présente des géométries complexes, sans altération de la porosité ni usure importante de l'outil. L'avantage est que le demi-produit à usiner est suffisamment stable à la pression pour l'usinage en vert, puisque la matière de substitution est encore présente dans les pores de l'ébauche crue au cours de l'usinage.

Title: Method and apparatus for controlling temperature uniformity of the burden in a direct reduction shaft furnace
Inventor: MONTAGUE STEPHEN C
IPC: C21B13/02
Filed: 2002-12-12
Abstract: A method and apparatus for increasing hydrocarbon input to a direct reduction shaft furnace (12) while controlling the temperature uniformity of the center portion (26) of the burden within the furnace (12) wherein the hydrocarbon gases used in the direct reduction may be preheated, which increases the temperature of the hydrocarbon gases, and therefore increases the resultant temperature of the upflowing gas as it rises from the lower section (66) of the furnace (12) into the center (26) of the burden. Alternatively, a portion of the upflowing gas may be removed before it enters the reduction zone of the furnace. The removed upflowing gas, known as hot bleed gas, may be ducted to the top gas scrubber (32) of the furnace or may be mixed with the main reducing gas stream of the furnace for reintroduction to the furnace.  Alternatively, hot reducing gas may be directly injected into the center portion (26) of the burden, offsetting the cooling effect of the upflowing gas. The centrally injected hot reducing gas may be split off from the main reducing gas stream or may be generated by a partial oxidation reactor.

The apparatus can include a support member configured to rest on a body of a recipient proximate to a coupling area. The support member can include a fir st coupler location configured to removably carry a first coupler proximate to a first coupling position of the body (22) of the recipient. A second coupler location of the support member is configured to removably carry a second coupler proximate to a second coupling position of the body (22) of the recipient. The first and second coupler locations can be arranged to guide t he practitioner to connect the couplers properly to the body. For example, the first coupler location can be positioned closer than the second coupler location to the first coupling position. Accordingly, practitioners can be more likely to connect the first and second couplers to the correct coupling position on the body (22) of the recipient.
