Patent number: 11938326Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.Type: GrantFiled: February 18, 2022Date of Patent: March 26, 2024Assignee: Medtronic, Inc.Inventors: Hyun J.

Publication number: 20130174817Abstract: An exhaust system and method for optimizing the efficiency of an internal combustion engine from which spent gas emerges. Spent gas is fed to an exhaust housing that accommodates a venturi. Part of the spent gas travels through the venturi and part travels outside the venturi. Across the mouth of the venturi sits a directing valve plate that can be moved, thereby opening or closing the path through the venturi. Some of the spent gas is reflected rearwardly from the venturi and thus reenters the cylinder. Upon doing so, the reflected spent gas occupies some of the space above the piston, lowers combustion pressure and reduces the velocity and pressure of the gas flow emerging therefrom.Type: ApplicationFiled: January 5, 2012Publication date: July 11, 2013Inventors: Paul E. Reinke, Julie N. Brown

Patent number: 5119781Abstract: A method is described for controlling the injection of fuel in a direct injected, multi-cylinder internal combustion engine, to smooth transients in engine output torque associated with a deceleration fuel cut-off mode of engine operation. This is accomplished by detecting engine operating conditions that call for the initiation of a transition associated with the decelaration fuel cut-off engine operating mode. In response to the detected operating conditions, a transitional period is initiated, during which the injection of fuel into a varying portion of engine cylinders is then interrupted. When the transitional period is associated with entry into the deceleration fuel cut-off mode, the injection of fuel to a progressively increasing number of cylinders is interrupted. When the transitional period is associated with recovery from the deceleration fuel cut-off mode, the injection of fuel to a progressively decreasing number of engine cylinders is interrupted.Type: GrantFiled: February 28, 1991Date of Patent: June 9, 1992Assignee: General Motors CorporationInventors: Douglas E. Trombley, Kenneth J. Buslepp, Paul E. Reinke, Steven D. Stiles, Kenneth G. Macklem

Patent number: 5094206Abstract: A method is described for increasing engine braking, when a crankcase scavenged two-stroke engine is operated in a deceleration fuel cut-off mode. In response to the detection of operating conditions indicating engine operation in the deceleration fuel cut-off mode, the quantity of air inducted into the engine is decreased, for a predetermined period of time. After this period of time elapses, the quantity of air inducted into the engine is then increased. This is preferably accomplished by regulating the degree of opening of a throttle valve disposed within the engine air intake system. The initial closing of the throttle valve restricts air flow through the engine for a predetermined time, to maintain efficient catalyst operating temperatures in the engine exhaust system. During extended operation in the deceleration fuel cut-off mode, the throttle valve is opened, after the lapse of the predetermined time, to increase the quantity of air inducted by the engine.Type: GrantFiled: February 25, 1991Date of Patent: March 10, 1992Assignee: General Motors CorporationInventors: Kenneth J. Buslepp, Paul E. Reinke, Douglas E. Trombley

Patent number: 4987773Abstract: The mass of air available for combustion within a cylinder of a crankcase scavenged two-stroke engine is obtained by estimating the mass of air trapped within a crankcase chamber, prior to its transfer to the associated cylinder combustion chamber. The estimate for air mass is derived from the product of pressure of the air in the crankcase chamber and the crankcase chamber volume at a selected engine cycle position during that portion of the engine cycle when the air is trapped and undergoes compression within the crankcase chamber divided by a factor containing the trapped air temperature at the selected engine cycle position.Type: GrantFiled: February 23, 1990Date of Patent: January 29, 1991Assignee: General Motors CorporationInventors: Steven D.

Patent number: 4958516Abstract: A method and apparatus are described for determining the mass of air available for combustion within a cylinder of a crankcase scavenged two-cycle engine, without the use of a mass-air flow sensor. This is achieved by estimating the mass of air under compression within a crankcase chamber, prior to its transfer to a cylinder combustion chamber. The estimate for air mass is based upon the integration of crankcase pressure over the interval of decreasing crankcase volume, while air within the crankcase is under compression. The volume of the air within the crankcase chamber is derived as a function of engine cycle position, with crankcase air temperature being derived as a function of intake air temperature. Air pressure during compression is monitored with a crankcase pressure sensor. The estimate for air mass is corrected to account for air leakage and incomplete transfer of the air between the crankcase and combustion chambers.Type: GrantFiled: February 8, 1990Date of Patent: September 25, 1990Assignee: General Motors CorporationInventors: Steven D. Stiles, Paul E. Reinke, Aparicio J. Gomez
