Patent number: 12170688Abstract: A distributed denial of service attack is detected. In response to detection of the attack, application layer properties of network traffic associated with a web application under attack are analyzed. Changes to distributions of the application layer properties are identified. A signature is generated based, at least in part, on identifying a combination of application layer properties whose distributions have changed, and which identifies traffic increased since onset of the attack. A mitigation rule is generated based, at least in part, on the signature.Type: GrantFiled: September 30, 2021Date of Patent: December 17, 2024Assignee: Amazon Technologies, Inc.Inventors: Adriana-Maria Horelu, Jeffrey Allen Lyon, Robert Benjamin Lang, Saket Tomer, Krzysztof Jan Pado, John Shields, Ben Sangho Jae, Matthew Hyun Seok Lee

Patent number: 12155690Abstract: The present disclosure generally relates to systems and methods for utilization of network mitigation techniques in the form of null address routing to mitigate coordinated DDOS attacks. A monitoring and mitigation service can characterize a command and control node as compromised or otherwise manipulated for purposes of generating distributed attacks. The monitoring and mitigation service can then identify network mitigation information in the form of null routing addresses that will cause network communications associated with the identified command and control node to be terminated or otherwise not delivered to the intended network-based resources. The monitoring and mitigation service can propagate the null routing address to routing components. The network mitigation information can be associated with expiration criteria for the routing components that receive and implement the network mitigation technique.Type: GrantFiled: December 10, 2021Date of Patent: November 26, 2024Assignee: Amazon Technologies, Inc.Inventors: Kelly Anne Rooker, Thomas Bradley Scholl, Kushal Mall, Darshan Narayana Reddy, Lewis Iain McLean, Andrew Robert Hassall, Grace Marie Hatamyar, Bradford Sachin Chatterjee, Sidath Manawadu, Bobby Brown, John Shields, Karthik Chandrashekar

Patent number: 10144488Abstract: The present invention relates to a subsea structural connector (20) used in the offshore oil and gas industry for remotely joining elements of production and drilling vessel mooring systems and other subsea equipment. This invention relates to a connection mechanism that facilitates automatic latching of two components (1, 2) upon engagement, and then remotely controlled actuation of a device that secures the connection. Specifically, this invention relates to a securing mechanism that creates residual stress between the connected components (1, 2) such that the connector (20) can withstand high variable axial, shear, torsional and bending loads while minimizing the propensity for fatigue damage within the mechanism.Type: GrantFiled: December 19, 2012Date of Patent: December 4, 2018Assignee: SUBSEA RISER PRODUCTS LIMITEDInventors: John Shield, Michael Burt

Publication number: 20170240249Abstract: The present invention relates to a system used in the offshore renewables or oil and gas industries for providing articulation at the end of a mooring line or a riser. The design uses a nested rubber segment (14) and orthogonal cylindrical bearings (12) to provide articulation with low resistance at both small and large oscillation angles. A relative rotational force applied between the axially loaded member (1) and the anchor assembly (4) causes the angle of the axially loaded member (1) to change to reduce such forces. The securement assembly comprises a bearing assembly (10) arranged to provide rotation about a pin (11). The bearing assembly (10) is arranged to provide two distinct stages for relative rotation. In the first stage, small relative rotations are accommodated by the flexion or deformation in the rubber layer (14). This deformation of the rubber layer (14) enables the axially loaded member (1) to rotate around the pin (11) and move relative to the anchor assembly (4).Type: ApplicationFiled: September 17, 2015Publication date: August 24, 2017Applicant: SUBSEA RISER PRODUCTS LIMITEDInventor: John SHIELD

Patent number: 9650845Abstract: The connector includes a sleeve (4) which is screwed on to a thread (18) provided on an upper axial end of the lower riser section (1). The sleeve (4) encloses a lower end of an upper riser section (2) and is retained thereto. Once the sleeve (4) is secured to the lower riser section, this loosely secures the upper riser section (2) to the lower riser section (1). A tensioning tool then stretches the sleeve (4) upwardly and a retaining collar (5) is then maneuvered in order to retain the sleeve (5) in this tensioned state after the release of the tensioning tool. This creates a preloaded connection between the upper riser section (2) and the lower riser section (1).Type: GrantFiled: March 28, 2013Date of Patent: May 16, 2017Assignee: Subsea Riser Products LimitedInventors: John Shield, Stephen Scott

Publication number: 20160252051Abstract: A fuel feed system for a rotary-winged aircraft includes a fuel feed line extending from a fuel source to an engine and an engine fuel suction pump disposed at the fuel feed line to urge a flow of fuel through the fuel feed line to the engine. A collector is located along the fuel feed line between the fuel source and the engine to collect air-vapor bubbles which form in the flow of fuel. An air-vapor line extends from the top of the collector and merges with the fuel line section between the collector and the engine fuel pump. The air-vapor line is sized and configured to limit the flow of air-vapor from the collector to the engine fuel suction pump to a rate which the engine fuel suction pump can tolerate.Type: ApplicationFiled: December 6, 2013Publication date: September 1, 2016Applicant: Sikorsky Aircraft CorporationInventors: David R.
