Publication number: 20230248217Abstract: An endoscope for laparoscopic surgery, including a shaft with a central axis, a proximal end, a distal end and a first optical beam path with a prism at the distal end of the shaft and having light entrance and exit surfaces, a lens with an optical axis, the lens behind the prism considered from the distal end of the shaft, and beam deflecting optics behind the lens considered from the distal end of the shaft. The light entrance surface is oriented perpendicular to the central axis, and the light exit surface forms a first angle of inclination with a first spatial axis oriented orthogonal to the central axis. To increase the numerical aperture of the lens, the optical axis is arranged perpendicular to the light exit surface of the prism. As a result, the lens has a cross-sectional area that is larger than the light entrance surface of the prism.Type: ApplicationFiled: February 6, 2023Publication date: August 10, 2023Inventors: Stephan HUNZE, Eric MARKWEG, Matthias HÜBNER

Patent number: 11015538Abstract: A method for controlling a supercharging system for an internal combustion engine, the supercharging stage including a compressor and a turbine, and the turbine being settable with the aid of a VTG driving circuit. The method including: detecting an operating state setpoint variable, setting a maximum VTG control criterion for implementing the torque increase by an increase in a boost pressure. The setting of the maximum VTG control criterion comprising: ascertaining a setpoint boost pressure; ascertaining a VTG setpoint position as a function of the setpoint boost pressure; ascertaining an actual exhaust gas back pressure; ascertaining an actual exhaust gas pressure downstream from the turbine; ascertaining a maximum exhaust gas back pressure, taking into account the actual exhaust gas pressure downstream from the turbine; determining the VTG control criterion, based on the difference between the actual exhaust gas back pressure and the maximum exhaust gas back pressure.Type: GrantFiled: November 21, 2019Date of Patent: May 25, 2021Assignee: Volkswagen AktiengesellschaftInventors: Stefan Gebauer, Matthias Huebner

Patent number: 10876468Abstract: A method for controlling a turbocharging system with a turbocharging stage for an internal combustion engine, wherein the turbocharging stage comprises a compressor and a turbine and the turbine is adjustable via a VTG control. The method includes: acquiring an operating state target variable; adjusting a maximum VTG control criterion to implement the torque increase by increasing a boost pressure, wherein adjusting the maximum VTG control criterion includes: determining a target boost pressure; determining a VTG target position as a function of the target boost pressure; determining an actual exhaust back pressure; determining a maximum exhaust back pressure; determining the VTG control criterion taking into account the difference between the actual exhaust back pressure and the maximum exhaust back pressure. The VTG control criterion limits the VTG target position such that an accelerated adaptation of an actual boost pressure to the target boost pressure) takes place.Type: GrantFiled: July 11, 2019Date of Patent: December 29, 2020Assignee: Volkswagen AktiengesellschaftInventors: Matthias Huebner, Stefan Gebauer
