Patent number: 11941734Abstract: A robotic system may comprise a first robotic arm operatively coupleable to a first tool. The first tool has a first working end. The system may also comprise an image capture device, a display, and a processor. The processor may be configured to cause an image of a work site, which was captured by the image capture device from a perspective of an image reference frame, to be displayed on the display. The image of the work site includes an image of the first working end of the first tool. The processor may also determine a position of the first working end of the first tool in the image of the work site and render a tool information overlay at the position of the first working end of the first tool in the image of the work site. The tool information overlay visually indicates state information for the first tool. The processor may also change the tool information overlay while the first tool is in a first operational state by changing a brightness of the tool information overlay.Type: GrantFiled: March 26, 2021Date of Patent: March 26, 2024Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Brandon D. Itkowitz, Simon P. DiMaio, Daniel J. Halabe, Christopher J. Hasser, Brian David Hoffman, David Q. Larkin, Catherine J. Mohr, Paul W. Mohr, Tao Zhao, Wenyi Zhao

Patent number: 11828252Abstract: An intake air circuit is structured to transmit intake air from a turbocharger compressor to an intake manifold of an engine. A charge air cooler (“CAC”), a bypass line, and a bypass heater are each positioned along the intake air circuit in parallel with each other. A first control valve is structured to controllably divert the intake air around the CAC. A second control valve is structured to controllably divert the intake air around at least one of the bypass line and the bypass heater. A controller operatively coupled to each of the engine, and the first and second control valves is structured to control each of the first and second control valves to cause the intake air to flow along a determined desired flow path based on each of measured ambient temperature and measured engine load.Type: GrantFiled: July 8, 2021Date of Patent: November 28, 2023Assignee: Cummins Inc.Inventors: J.

Patent number: 11686239Abstract: An intake manifold is provided. A first inlet is structured to receive pressurized intake air from a turbocharger. A second inlet is structured to receive exhaust gas recirculation gas from an exhaust gas recirculation system. A third inlet is structured to receive fuel from a fuel line. A plurality of outlets are structured to be fluidly coupled to an engine. An intake manifold passage extends between each of the first, second, and third inlets, and the plurality of outlets. The intake manifold passage is shaped so as to cause at least two reversals in flow direction of each of the intake air, the exhaust gas recirculation gas, and the fuel through the intake manifold passage so as to improve mixing of each of the intake air, the exhaust gas recirculation gas, and the fuel.Type: GrantFiled: April 8, 2022Date of Patent: June 27, 2023Assignee: Cummins Inc.Inventors: Daniel J.
