Publication number: 20240111143Abstract: A method for operating a microscopy system includes irradiating a region segment of a first region by a light source with light at a first wavelength ?1 and a first luminous intensity L1, determining a substance-specific parameter within the region segment as a response to being irradiated by the light source, and repeating the steps for all region segments within the first region. In addition, the disclosure relates to a microscopy system, and a calibration method for a microscopy system.Type: ApplicationFiled: December 7, 2023Publication date: April 4, 2024Inventors: David Reichert, Marco Wilzbach, Stefan Saur, Christoph Hauger, Artur Hoegele, Mikael Timo Erkkilä, Holger Matz, Rainer Leitgeb, Angelika Unterhuber, Marco Andreana

Patent number: 9958017Abstract: A metering device for controlling an oil delivery rate for a wet-running clutch. The wet-running clutch has at least one pair of interacting friction surfaces and an actuation unit for actuating the wet-running clutch. The actuation unit has an axially supported support disk and an axially displaceable thrust disk, wherein the thrust disk and the support disk are rotatable relative to one another. The metering device has a first component which is connected fixedly with respect to a housing, and a second component which is connected to the thrust disk in a rotationally conjoint and axially relatively displaceable manner.Type: GrantFiled: March 24, 2014Date of Patent: May 1, 2018Assignee: Magna Powertrain AG & Co KGInventor: Stefan Leitgeb

Patent number: 9333855Abstract: A transfer case for transferring a driving torque of a driving unit of a motor vehicle to a first axle and a second axle of the motor vehicle. The transfer case includes a housing, an input shaft allocated to the driving unit, a first driven shaft allocated to the first axle, and a second driven shaft allocated to the second axle and offset parallel to the input shaft. The transfer case further includes an offset drive for transmitting driving torque from the input shaft to the second driven shaft. The offset drive comprises a gear wheel coaxial to the input shaft or to the driven shaft. The gear wheel is rotatably mounted on a section of the housing.Type: GrantFiled: August 29, 2012Date of Patent: May 10, 2016Assignee: Magna Powertrain AG & Co KGInventors: Markus Krogger, Stefan Leitgeb, Alois Lafer
