Patent number: 9467332Abstract: A system includes a network element communicatively coupled to another network element through an intraportal link forming a node portal. The network element is communicatively coupled to a source network element within a network attached to the node portal. The network element is configured to monitor a protect path for an automatic protection switching (“APS”) message from the source network element, determine that the APS message has been received, monitor an intraportal link for an expected message from the other network element, determine that the expected message has not been received, monitor integrity of the intraportal link, determine that the intraportal link has failed and determine that the other network element has failed based upon determining that that the APS message has been received, that the expected message has not been received, and that the intraportal link has failed.Type: GrantFiled: February 15, 2013Date of Patent: October 11, 2016Assignee: Fujitsu LimitedInventors: Donald O'Connor, Virgil Vladescu

Patent number: 9264300Abstract: A method for linear protection for a network element communicatively coupled to another network element included in a node portal located at the edge of an administrative network domain includes exchanging linear automatic protection switching (“APS”) messages with clients in the administrative network domain over one or more path pairs. The path pairs include a working path communicatively coupling a client and the network element and a protect path communicatively coupling a client and the other network element. The method also includes translating the linear APS messages into a shared mesh protection message and exchanging the shared mesh protection message between the network element and the other network element over an intraportal link. The shared mesh protection messages include information concerning a plurality of working paths.Type: GrantFiled: March 21, 2013Date of Patent: February 16, 2016Assignee: Fujitsu LimitedInventors: Donald O'Connor, Virgil Vladescu

Patent number: 8772427Abstract: A modular process for organosolv fractionation of lignocellulosic feedstocks into component parts and further processing of said component parts into one or more of a de-lignified cellulose stream, a sugar stream, small-chain alcohol streams and four structurally distinct classes of lignin derivatives. The modular process comprises a first processing module configured for digesting lignocellulosic feedstocks with an organic solvent thereby producing a cellulosic solids fraction and a liquid fraction, a second processing module configured for recovering small-chain alcohols and optionally a first class of lignin derivatives from the cellulosic solids fraction, a third processing module configured for recovering from the liquid fraction at least one of a second class and a third class of lignin derivatives or mixtures thereof, and waste stream comprising a fourth class of lignin derivatives. The fourth processing module may optionally recover the fourth class of lignin derivatives.Type: GrantFiled: May 30, 2012Date of Patent: July 8, 2014Assignee: Lignol Innovations Ltd.Inventors: Christer Hallberg, Donald O'Connor, Michael Rushton, Edward Kendall Pye, Gordon Gjennstad, Alex Berlin, John Ross McLachlan, Raymond Ma

Patent number: 8571018Abstract: An advanced SONET add/drop multiplexer capable of supporting packet over SONET and multiprotocol label switching. The add/drop multiplexer is capable of adding and/or dropping both STM and packet traffic, such as Internet Protocol traffic. This SONET add/drop multiplexer allows Internet Protocol streams which are added or dropped at different nodes to be carried over the same SONET path in a network, thereby greatly saving bandwidth.Type: GrantFiled: July 12, 2007Date of Patent: October 29, 2013Assignee: Fujitsu LimitedInventor: Donald O'Connor

Patent number: 8058041Abstract: A process for simultaneous saccharification and fermentation of a cellulosic solids fraction extracted from a lignocellulosic feedstock. The viscosity of the cellulosic solids fraction is reduced by intermixing with a liquid carbohydrate stream. A suitable liquid carbohydrate stream is a de-lignified liquids fraction that was previously separated from the solids fraction during processing of the lignocellulosic feedstock. Alternatively, the viscosity of the solids fraction may be reduced by commingling with a liquid carbohydrate stream comprising one or more monosaccharides. The reduced-viscosity cellulosic solids fraction is then commingled with a fermentative microbial inoculant and a cellulosic biomass-degrading enzyme composition. The commingled mixture is maintained in a pressurized reaction vessel under elevated temperatures to enable simultaneous enzymatic hydrolysis of the cellulosic solids to monosaccharides and fermentation of the monosaccharides to produce an ethanolic beer.Type: GrantFiled: July 3, 2008Date of Patent: November 15, 2011Inventors: Alex Berlin, Edward Kendall Pye, Donald O'Connor
