Patent number: 11936763Abstract: Embodiments of the present invention provide methods, computer program products, and systems. Embodiments of the present invention can identify a network request as being deferrable and embed data of the deferrable network request within a header of a suitable carrier network request for sending to a remote server. Embodiments of the present invention can receive a carrier network request with embedded data of a deferrable network request within a header of the carrier network request. Embodiments of the present invention can then parse the embedded data from the header into a separate request message for actioning at the server.Type: GrantFiled: October 28, 2020Date of Patent: March 19, 2024Assignee: International Business Machines CorporationInventors: Matthew Paul Chapman, Chengxuan Xing, Ashley Donald Harrison, Samuel David Goulden

Publication number: 20240089741Abstract: Described herein are systems and methods for assigning and managing RF communication links between ground-based stations and airborne assets. In one or more examples, a pilot or other user of the systems and methods described herein can generate and transmit a flight plan to a spectrum management system. Additionally, or alternatively, the pilot or use can also transmit additional information to the spectrum management system such as the type of aircraft/radio configuration that they will be using during a flight, and a request for a certain amount of data throughput that they want to have access to during the flight. In one or more examples, upon receiving the flight plan and/or information from the pilot, the spectrum management system can proceed to match the user's desired flight plan with one or more RF spectrum resources for the airborne radio of the pilot's UAV to use during their planned flight.Type: ApplicationFiled: July 11, 2023Publication date: March 14, 2024Inventors: Osama Hussein TARRAF, Alistair Charles Peter BRADEN, Tamara Lynne CASEY, Shane David CHAPMAN, Michael Robert GAGNE

Patent number: 11767749Abstract: A drilling system configured to reduce friction during slide drilling. The drilling system has a drill string comprising a fluid-driven drill stage such as a mud motor; a variable frequency drive configured to oscillate the drill string via a quill and a sensor array. The sensor array measures the torque applied to the quill and the angular position of the quill. A controller is used to control the variable frequency drive based on the determined applied torque and quill angular position to meet predetermined oscillation turn-around criteria and to reduce the time to reduce the angular velocity of the quill from a maximum rotational speed to zero in an oscillation cycle.Type: GrantFiled: April 13, 2021Date of Patent: September 26, 2023Assignee: Ensign Drilling IncInventors: Jarrod David Chapman, Chiranjit Saha, Sean Timothy Halloran

Patent number: 11530018Abstract: A subsea vehicle capable of supporting inspection of underwater objects while underway includes a body that provides a capability to allow the subsea vehicle to submerge underwater and follow or position near an object while maintaining an orientation to the object appropriate for inspection of, and safety requirements for, the object. The vehicle includes a set of deployable, semi-rigid arms to support the movement of inspection sensor probes near or lightly touching the inspection target with the probes. A controller helps tracks the intended inspection object using various sensor inputs along with a priori knowledge of the object to drive and position the subsea vehicle such that the appropriate orientation to the inspection target is maintained.Type: GrantFiled: February 28, 2019Date of Patent: December 20, 2022Assignee: Oceaneering International, Inc.Inventors: Jami Joseph Cherami, David Chapman, Chiun-Hong Chien, Sara Rayburn

Patent number: 11427377Abstract: A tearable leak-resistant container is provided with creases, partial perforation along selected creases, adhesion of flaps, and a collapsed position to permit rapid reconfiguration to an expanded position. The expanded position of the container enables enhanced filling with food ingredients and transportation without spillage. The adhered flaps provide enhanced leak resistance, and the perforated creases permit disassembly of the container to improve access to the food contained within.Type: GrantFiled: January 8, 2021Date of Patent: August 30, 2022Assignee: Southern Champion Tray, L.P.Inventors: Neha Mardi, David Chapman, Doug Ehman

Publication number: 20220051339Abstract: The present invention creates a structure and system which reduces the expenses associated with selling, administering, and managing annuities. The present invention provides a well-managed set of TDFs that offer participants the opportunity, but not the obligation, to purchase an annuity at any time using all or a portion of a participant's plan account invested in the target date fund. This functionality permits participants to annuitize all or a portion of their account balance. The present invention further provides cheaper and easier access to annuity options than are otherwise available in the marketplace because no commissions will be paid to an insurance broker. The present invention provides to plan participants in longer-dated TDFs an investment opportunity in the reinsurer.Type: ApplicationFiled: August 13, 2020Publication date: February 17, 2022Inventors: Donald Andrews, David Chapman, Jodan Ledford
