Patent number: 11939931Abstract: An internal combustion engine controller comprising a memory and a processor is provided. The memory is configured to store a plurality of control maps, each control map defining a hypersurface of actuator setpoints for controlling an actuator of the internal combustion engine based on a plurality of input variables to the internal combustion engine controller. The processor comprises an engine setpoint module and a map updating module. The engine setpoint module is configured to output a control signal to each actuator based on a location on the hypersurface of the respective control map defined by the plurality of input variables. The map updating module is configured to calculate an optimised hypersurface for at least one of the control maps. The optimised hypersurface is calculated based on a real-time performance model of the internal combustion engine comprising sensor data from the internal combustion engine and the plurality of input variables.Type: GrantFiled: April 20, 2020Date of Patent: March 26, 2024Assignee: Perkins Engines Company LimitedInventors: Gavin Williams, Peter Ladlow, Max Best, Mark Scaife

Publication number: 20220346908Abstract: Disclosed adjustable retaining arm systems can include a multi-segmented, articulable arm that holds one or more interchangeable tools and can be made relaxed to set a desired position and made rigid to fix the desired position by adjusting tension in a cable running through the arm. The arm can quickly attach and detach from a support structure. The support structure include a cable tensioning system, sensors, control system, power system, etc. A user input device, such as a foot pedal or button on the arm, can be used by a surgeon to change the arm between relaxed and rigid states. The arm and attachable tools can be detachable, disposable and/or sterilizable, while other system components can remain mounted in a fixed location as the arm is removed and replaced. The arm can hold multiple tools in any desired orientation around subject work location.Type: ApplicationFiled: July 11, 2022Publication date: November 3, 2022Applicants: University of Pittsburgh-Of the Commonwealth System of Higher Education, UPMCInventors: Jeffrey S. Vipperman, Christopher Michael Dumm, Garth Abraham Elias, Tyler Michael Ferris, Mark Scaife, Peter David Allen

Patent number: 8011179Abstract: A method is provided for compensating for factors affecting particulate matter accumulation within an aftertreatment element of an engine exhaust system. The method comprises determining rate of change of flow resistance through the aftertreatment element with time. Regeneration is periodically initiated to reduce particulate matter accumulation within the aftertreatment element. Rate of change of flow resistance through the aftertreatment element over time is correlated with at least a model of particulate matter accumulation within the aftertreatment element and a model of regeneration frequency of the aftertreatment element, based on predetermined values for particulate matter accumulation and regeneration frequency. Action, at least including increasing regeneration frequency, is initiated to compensate for an increased rate of particulate matter accumulation in the aftertreatment element.Type: GrantFiled: May 31, 2007Date of Patent: September 6, 2011Assignee: Caterpillar Inc.Inventors: Mark Scaife, Trent Cleveland, Michael Lowe, Cornelius Opris, Evan Jacobson, Matthew R.
