Patent number: 11951042Abstract: A device and method for the pre-display of a spot pattern to be applied for a laser treatment of the eye. The spot patterns to be applied are displayed to the operator in advance with the aid of a target beam. The device for the pre-display of a spot pattern to be applied for a laser treatment of the eye includes a laser system and a scanning system for generating a target beam. Here, the laser system and the scanning system for generating the target beam are formed to generate one or more lines which overlie all the spots of the spot pattern of a planned laser treatment. The device and method are suitable for laser treatment of the retina, the trabecular meshwork as well as other regions. Here, it is irrelevant whether what the laser treatment to be applied is.Type: GrantFiled: April 4, 2019Date of Patent: April 9, 2024Assignee: Carl Zeiss Meditec AGInventors: Manfred Dick, Gerald Kunath-Fandrei, René Denner, Thomas Wurlitzer

Patent number: 9939396Abstract: A system for measuring the thermal diffusivity of a material includes a housing having an upper portion and a lower portion, a plate holding the material in a fixed position between the upper portion and lower portion of the housing, and a source at the lower portion of the housing projecting heat onto the material along a first axis that is perpendicular to the plate. A sensor at the lower portion of the housing is movable in relation to the plate and senses the heat radiating through the material along a second axis that is perpendicular to the plate and offset from the first axis. A controller receives data from the sensor and calculates the thermal diffusivity of the material.Type: GrantFiled: January 30, 2015Date of Patent: April 10, 2018Assignee: Netzsch-Gerätebau GmbHInventors: Marc-Antoine Thermitus, Martin Brunner, Juergen Blumm, Robert Campbell, Thomas Denner, Michael Gebhardt, Andreas Hartinger, Thilo Hilpert, Stefan Lauterbach, André Lindemann, Matthias Schödel, Andreas Strobel, Jürgen Tschöpel

Patent number: 9816869Abstract: A method for evaluating a measurement result of a thermal analysis. A program-controlled computer unit is used to calculate at least one probability of the agreement of the measurement result with at least one dataset previously stored in the computer unit, wherein this calculation is based on a comparison of effect data previously extracted from a measurement curve of the thermal analysis with corresponding stored effect data of the dataset. The evaluation can advantageously include, an automatic recognition and classification of measurement curves and can be carried out in particular more efficiently, more economically and more quickly than previously, with at the same time a high quality of evaluation.Type: GrantFiled: July 11, 2014Date of Patent: November 14, 2017Assignee: Netzsch-Gerätebau GmbHInventors: Thomas Denner, Juergen Blumm, Otto Max Schaefer, Markus Hollering, Thilo Hilpert, Alexander Frenzl, Stefan Lauterbach, Andreas Strobel, Gabriele Kaiser, Stephan Knappe, Rolf Preuss, Michael Gebhardt, Elena Moukhina, Alexander Schindler, Matthias Gradl, Gunther Herr, André Nijmeh, Stefan Schmoelzer, Markus Meyer

Patent number: 9310259Abstract: A method for conducting a differential thermal analysis, in which a sample disposed in a temperable sample space is tempered according to an essentially linear temperature program extending from a start temperature to an end temperature, such that, from the result of a measurement of the sample temperature conducted during tempering at a number of measurement time points, a DTA signal is calculated as the difference between a measured sample temperature and a reference temperature calculated according to a temperature curve model. According to the invention, for every measurement time point, the relevant reference temperature is calculated by the following steps: (a) establish a time interval containing the relevant measurement time point; (b) calculate a non-linear adjustment function for the measured sample temperature curve in the time interval; and (c) calculate the reference temperature as a value of the adjustment function for the measurement time point.Type: GrantFiled: January 24, 2014Date of Patent: April 12, 2016Assignee: Netzsch-Gerätebau GmbHInventors: Thomas Denner, Juergen Blumm, Otto Max Schaefer, Markus Hollering, Thilo Hilpert, Alexander Frenzl, Stefan Lauterbach, Andreas Strobel, Rolf Preuss, Michael Gebhardt, Elena Moukhina, Alexander Schindler, Mathias Gradl, Gunter Herr, Stephan Knappe, Markus Meyer, Gabriele Kaiser, Andre Nijmeh
