Patent number: 8743454Abstract: An optical amplifier includes at least one pump source and an optical fiber cable which includes an amplifying optical fiber and a pump optical fiber that are defined by respective lengths. The amplifying optical fiber and the pump optical fiber are coated with a common coating along a portion of their respective lengths, and the fibers are in optical contact with each other along a coating length within the common coating. The common coating has a refractive index which is lower than a refractive index of a cladding material of the pump optical fiber. The fibers are made substantially from glass. The amplifying optical fiber includes a core and a cladding, and is doped with a rare earth dopant. The pump optical fiber is defined by a first end and a second end, the first end of the pump optical fiber being connected to the pump source.Type: GrantFiled: August 21, 2012Date of Patent: June 3, 2014Assignee: SPI Lasers UK LtdInventors: Anatoly Borisovich Grudinin, Dave Neil Payne, Paul William Turner, Lars Johan Albinsson Nilsson, Michael Nickolaos Zervas, Morten Ibsen, Michael Kevan Durkin

Patent number: 8275757Abstract: A method is described for monitoring a plurality of process instances, such as business process instance. The method comprises: providing a model object reflecting a workflow common to the process instances, the model comprising a plurality of nodes with at least some of the nodes being capable of assuming at least active and blocked states; receiving events and changing the states of the nodes in corresponding model object instances in accordance with the events received so as to reflect the status of the process instances, repeatedly determining an “at risk” state indicator for the model instances, the “at risk” state indicator when set for a model instance indicating that the corresponding workflow instance is in a state in which it cannot progress to a normal completion without encountering a node in the blocked state.Type: GrantFiled: June 14, 2005Date of Patent: September 25, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Maurice Haman Abraham, Paul William Turner, Michael Carter
