Patent number: 9721211Abstract: A method and apparatus for processing data, the data including a set of one or more system inputs; and a set of one or more system outputs; wherein each system output corresponds to a respective system input. Each system input can include a plurality of data points, such that at least one of these data points is from a different data source to at least one other of those data points. The method includes performing a kernel function on a given system input from the data and a further system input to provide kernelized data; and inferring a value indicative of a significance of data from a particular data source; wherein the inferring includes applying a regression technique to the kernelized data.Type: GrantFiled: May 31, 2012Date of Patent: August 1, 2017Assignee: BAE SYSTEMS plcInventors: David Nicholson, Christopher Mark Lloyd, Steven Reece, Stephen John Roberts

Patent number: 8706676Abstract: The method includes receiving a plurality of target observations from a respective plurality of sensors and using the target observations to compute target state estimates. Each of the target state estimates is assessed to check if it suffers from one of a set of modelled possible fault types. The target state estimates are adjusted to compensate for any modelled fault type when it is assessed to be suffering from that fault type. A reliability value is computed for each of the target state estimates and the target state estimates are fused together based on the computed reliability values to produce a fused target state estimate.Type: GrantFiled: June 22, 2010Date of Patent: April 22, 2014Assignee: BAE Systems PLCInventors: Christopher David Claxton, David Nicholson, Steven Reece, Stephen John Roberts

Patent number: 8610775Abstract: A method of estimating states of a plurality of targets tracked by a plurality of sensors. The method includes obtaining a plurality of data sets based on measurements taken by a plurality of sensors, each data set including information on states of a plurality of targets. The method then generates a plurality of target correlation data sets describing correlation of the targets within a first data set and at least one other data set. A Generalised Covariance Union (GCU) technique is used to merge at least some of the plurality of target correlation data sets to generate an estimate of the states of the plurality of targets.Type: GrantFiled: July 30, 2009Date of Patent: December 17, 2013Assignee: BAE Systems PLCInventors: Christopher David Claxton, David Nicholson, Steven Reece, Stephen John Roberts

Patent number: 8104484Abstract: A smoking article such as a cigarette, or a smoke filter or other component thereof, comprises a catalyst for the oxidation of carbon monoxide to carbon dioxide. The catalyst comprises gold, and an oxide of zinc or titanium. Titania and mixed oxides of zinc and copper or aluminum are preferred (TiO2, ZnO, ZnAlOx or CuZnOx). The gold preferably comprises species in the metallic state)(Au0), together with species in an oxidized state (Au?+).Type: GrantFiled: May 24, 2005Date of Patent: January 31, 2012Assignee: British American Tobacco (Investments) LimitedInventors: Peter James Branton, Stephen John Roberts, Elma van der Lingen

Patent number: 6397951Abstract: A marine riser, particularly but not exclusively for use in connecting a subsea well installation to a dynamically positioned servicing vessel, comprises at least one section formed from rigid pipe and at least one section formed from flexible pipe. Preferably, the upper and lower sections (10, 12) are formed from fixed lengths of flexible pipe and the central section is formed from a plurality of lengths of rigid pipe which may be assembled to make up any required length. The riser may be deployed from a moonpool of the vessel and serves to accommodate movements of the vessel on the surface. This allows the use of a dynamically positioned service vessel rather than a conventional drilling rig.Type: GrantFiled: March 19, 1999Date of Patent: June 4, 2002Assignee: Coflexip Stena Offshore LimitedInventor: Stephen John Roberts

Patent number: 5971666Abstract: An apparatus for laying marine pipelines of the type in which the pipeline is assembled along a horizontal axis on board a pipelaying vessel prior to being launched therefrom; in which the pipeline is plastically bent to a desired launch angle and, in most cases, at least partially straightened thereafter. In preferred embodiments, the pipeline is bent through an angle greater than 90.degree.. In the most preferred embodiments, the pipeline is diverted through an angle of substantially 270.degree., plus or minus an angle allowing variation in the launch angle from the vertical, and crosses itself prior to entering the water. The pipeline (102) is diverted by being passed around a wheel-like diverter structure (104), the pipeline being assembled in multiple fabrication lines to produce stalks which are aligned and connected in a central firing line prior to being fed around the diverter structure. Other variations are also described.Type: GrantFiled: November 26, 1996Date of Patent: October 26, 1999Assignee: Coflexip Stena Offshore LimitedInventors: Robert George Martin, Donald Carmichael, Stephen John Roberts

In preferred embodiments, the pipeline is bent through an angle greater than 90.degree.. In the most preferred embodiments, the pipeline is diverted, initially upwardly, through an angle of substantially 180.degree. sheave (28), prior to being bent downwards to the desired launch angle by an adjustable angle ramp (30). Other variations are also described.Type: GrantFiled: November 26, 1996Date of Patent: November 17, 1998Assignee: Coflexip Stena Offshore LimitedInventors: Robert George Martin, Donald Carmichael, Stephen John Roberts
