Patent number: 11759105Abstract: An illumination system for producing a spatially distributed illumination pattern for measuring the cornea of an eye and, in particular, for determining the topography of the eye. In so doing, the system facilitates distance-independent measurements. The illumination system includes an illumination unit, an optical element for collimating the illumination light and a unit for producing a spatially distributed illumination pattern in the form of a fraxicon. In particular, the illumination unit includes a plurality of illumination modules which are arranged such that each illumination module illuminates part of the fraxicon, and consequently a full-area illumination is facilitated. The system for producing a spatially distributed illumination pattern serves to determine the topography of the cornea of an eye. Here, the system is designed as a compact module, and so it can be easily combined with other measurement systems, without interfering with the beam paths thereof.Type: GrantFiled: August 31, 2017Date of Patent: September 19, 2023Assignee: Carl Zeiss Meditec AGInventors: Beate Böhme, Rico Fuchs, Günter Rudolph, Michael Güntzschel, Jörg Meissner, Thomas Mohr, Daniel Bublitz

Patent number: 10893799Abstract: A method for determining the topography of the cornea of an eye on the basis of an optical, contactless data capture. In the method for determining the topography of the cornea of an eye, which is based on a deflectometric method, the deflectometric measurements are carried out with the aid of a keratometric method by virtue of additional OCT-based scans being made at the keratometric measurement points, wherein the two measurement systems are registered to one another and both the keratometric and the OCT-based measurement values are recorded and used for mutual calibration to determine and output the topographic data. The proposed method serves to determine the topography of the cornea of an eye. It is helpful to ascertain the topography in order to be able to draw conclusions about possible pathological changes. Moreover, the exact measurement of the corneal topography is of great importance for correcting refractive errors.Type: GrantFiled: September 5, 2019Date of Patent: January 19, 2021Assignee: Carl Zeiss Meditec AGInventors: Manfred Dick, Ferid Bajramovic, Wei-Jun Chen, Tobias Bühren, Matthias Reich, Jörg Meissner, Martin Kühner

Patent number: 8897981Abstract: Method for determining an adjustment parameter in a hydraulic actuator arrangement for a motor vehicle drivetrain. The actuator arrangement has a pump and a hydraulic cylinder. A pressure port of the pump is connected to a port of the hydraulic cylinder. The adjustment parameter is a function of the volume of the fluid that must be delivered by the pump in order to realize a predetermined operating point of the actuator arrangement. The operating point is defined by a value pair of an operating point rotational speed value of the pump and an operating point control value of the pump. The method has the steps: regulating the pump to the operating point rotational speed value such that the pump delivers a fluid volume flow rate corresponding to the operating point rotational speed value; and integrating the fluid volume flow rate over the time until a termination operating state of the actuator arrangement, in which the control value of the pump is less than or equal to the operating point control value.Type: GrantFiled: October 24, 2013Date of Patent: November 25, 2014Assignee: GETRAG Getriebe- und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KGInventors: Jörg Meissner, Hans-Peter Moosmann

Patent number: 8660764Abstract: A method for actuating a friction clutch, in particular for a motor vehicle drivetrain. The friction clutch is acted on with a clutch pressure generated by a hydraulic actuator arrangement which has an electrically actuable fluid source and which has a hydraulic actuator whose state is characterized by an actuator actual value. The actuator actual value is related to the clutch pressure. The method has the steps: forming a regulation-oriented model of the actuator arrangement, which model has at least one fluid source actuating variable as an input and at least the actuator actual value as a flat output and which model can be inverted; forming an inverse model of the actuator arrangement; and inputting an actuator nominal value into the inverse model and using the model actuating variable which emerges therefrom for actuating the fluid source.Type: GrantFiled: May 11, 2011Date of Patent: February 25, 2014Assignee: GETRAG Getriebe- und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KGInventors: Thomas Gorius, Joerg Meissner

Patent number: 8577573Abstract: A method for setting the engagement point of a friction clutch of a multi-step transmission for a motor vehicle. The friction clutch can be activated, controlled, by means of a clutch actuator. A set point value of the clutch actuator is set for the engagement point of the friction clutch as a function of a time profile of a physical variable which occurs starting from a transition state after activation of the friction clutch to a transition value.

Patent number: 8504260Abstract: A method for activating a clutch of a vehicle drive train. A controller of an electronic control unit generates an electrical desired-value signal corresponding to a desired pressure with which the clutch is to be acted upon. The control unit receives from a sensor an electrical actual-value signal which is to correspond to an actual pressure with which the clutch is acted upon. The sensor measures the pressure at a measurement location which is connected via a transfer link to an action location at which the clutch is acted upon with a clutch pressure. The actual-value signal passes through a transfer element having a delay property before it is delivered to the controller.Type: GrantFiled: January 26, 2009Date of Patent: August 6, 2013Assignee: GETRAG Getriebe-und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KGInventors: Thorsten Stepper, Joerg Meissner, Ralf Trutschel
