Publication number: 20240091422Abstract: A renal therapy system is disclosed. In an example, the renal therapy system includes a home renal therapy machine that stores, to a log file, dates of when renal therapies were performed and a type of each renal therapy that was performed. The system also includes a server that receives the log file from the home renal therapy machine. The server compares the dates and types of performed renal therapies stored in the log file to a device program that specifies dates for performing renal therapies and the types of renal therapies to be performed. The server displays a flag in a user interface of a clinician computer when there is a deviation from the comparison.Type: ApplicationFiled: November 20, 2023Publication date: March 21, 2024Inventors: Neil Tiwari, Joshua James Miller, Marc Steven Minkus, Matthew R. Muller, Derek Wiebenson, Douglas L. Wilkerson, Timothy G. Robinson, Anders J. Wellings, Kathryn Louise Hansbro, Borut Cizman, Brian S. Kunzeman, Robin D. Cooper, Timothy L. Kudelka, Angelo A.

Patent number: 8443602Abstract: An exhaust aftertreatment system for an internal combustion engine includes an exhaust manifold that is configured for fluid communication with an exhaust port to receive an exhaust gas flow. It also includes a primary turbocharger having a turbine inlet configured for fluid communication with the exhaust manifold to receive the exhaust gas flow and pass it to an outlet. It also includes an exhaust bypass valve that is operable for movement between an open position and a closed position, the exhaust bypass valve having an inlet that is configured for fluid communication with the exhaust manifold in the open position to receive the exhaust gas flow and pass it to an outlet. Still further, it includes an exhaust aftertreatment device configured for thermal communication with the exhaust manifold, the device having an inlet configured for fluid communication with the turbine and bypass outlets to receive the exhaust gas flows therefrom.Type: GrantFiled: March 30, 2010Date of Patent: May 21, 2013Assignees: GM Global Technology Operations LLC, Ricardo, Inc.Inventors: David Bennet, Brian G. Cooper, Huntly W. Thomas, Nick Winder

Patent number: 8312708Abstract: A closely-coupled exhaust aftertreatment system includes a first exhaust conduit comprising a first valve operable between a first position promoting an exhaust flow within the first exhaust conduit to an inlet of a first oxidation catalyst and a second position promoting the exhaust gas flow within a second exhaust conduit. It also includes a third exhaust conduit fluidly coupled to an outlet of the OC and comprising a second valve operable between a first position promoting an exhaust flow within the third exhaust conduit to an inlet of a particulate filter (PF) and a second position promoting the exhaust gas flow through a fourth exhaust conduit to an inlet in the second exhaust conduit. It further includes a turbocharger fluidly coupled to the second exhaust conduit downstream of the inlet and a selective catalyst reduction (SCR) catalyst that is located downstream of the turbocharger and upstream of the PF.Type: GrantFiled: March 30, 2010Date of Patent: November 20, 2012Assignee: GM Global Technology Operations LLCInventors: David Bennet, Brian G.

Patent number: 8011890Abstract: An air-cooled component such as a turbine stator vane, has a row of cooling passages extending from the interior of the vane to the exterior. The passages are inclined to a plane perpendicular to the row. The angle of inclination of each passage varies with the position of the passage along the row. The arrangement assists in avoiding local overheating of the vane surface.Type: GrantFiled: October 23, 2007Date of Patent: September 6, 2011Assignee: Rolls-Royce PLCInventors: Sean A. Walters, Kevin P. Self, Brian G. Cooper

Patent number: 5507621Abstract: A gas turbine engine is provided with turbine stators which have hollow aerofoils. The aerofoils are internally cooled by a flow of air the path of which is defined by walls. The wall has a curved deflector at its outer end which causes air to flow over the wall end and down the other side of the wall. An extension member ensures that the air does not break away from the surface of the wall and is preferably made from sheet metal so as to provide a light, easily made structure.Type: GrantFiled: January 30, 1995Date of Patent: April 16, 1996Assignee: Rolls-Royce plcInventor: Brian G. Cooper

Patent number: 5193975Abstract: The present invention relates to cooled gas turbine engine aerofoils particularly for turbine stator vanes or tubine rotor blades. The leading edge region of a hollow aerofoil is provided with rows of cooling air passages, which are arranged, in operation, to direct cooling air in the opposite direction to the local flow of the hot gas stream. The cooling air passages are substantially parallel, and have relatively large diameters to reduce the possibility of blockage of the cooling air passages by sand. An air guide tube in the hollow aerofoil is provided with large apertures at its leading edge to minimize the area for sand to adhere to.Type: GrantFiled: February 4, 1991Date of Patent: March 16, 1993Assignee: Rolls-Royce plcInventors: Jonathan G. Bird, Brian G. Cooper

Patent number: 5073086Abstract: A gas turbine engine turbine aerofoil blade includes an aerofoil portion having pressure and suction flanks. The flanks are internally interconnected by wall member which cooperates with the flanks to define first and second cooling passage portions which are interconnected by a bend portion. The wall member is locally thickened adjacent the bend portion. In the second cooling passage portion the locally thickened wall member portion progressively increases in thickness towards at least one of the flanks so as to eliminate any acute angle between the flanks and the thickened wall member portion adjacent thereto.Type: GrantFiled: June 19, 1991Date of Patent: December 17, 1991Assignee: Rolls-Royce plcInventor: Brian G. Cooper
