Patent number: 11971663Abstract: Provided are light sources and methods of controlling them, and devices and methods for use in measurement applications, particularly in metrology, for example in a lithographic apparatus. The methods and devices provide mechanisms for detection and/or correction of variations in the light source, in particular stochastic variations. Feedback or feedforward approaches can be used for the correction of the source and/or the metrology outputs. An exemplary method of controlling the spectral output of a light source which emits a time-varying spectrum of light includes the steps of: determining at least one characteristic of the spectrum of light emitted from the light source; and using said determined characteristic to control the spectral output.Type: GrantFiled: July 7, 2020Date of Patent: April 30, 2024Assignee: ASML Netherlands B.V.Inventors: Marinus Petrus Reijnders, Hendrik Sabert, Patrick Sebastian Uebel

Publication number: 20220236479Abstract: A method for manufacturing a capillary usable as part of a hollow-core photonic crystal fiber. The method includes obtaining a capillary having capillary wall including a first wall thickness; and chemically etching the capillary wall to reduce the wall thickness of the capillary wall. During performance of the etching, a control parameter is locally varied along the length of the capillary, the control parameter relating to reactivity of an etchant used in the etching, so as to control the etched wall thickness of the capillary wall along the capillary length. Also disclosed is a capillary manufactured by such a method and various devices including such a capillary.Type: ApplicationFiled: April 13, 2022Publication date: July 28, 2022Applicant: ASML NETHERLANDS B.V.Inventors: Hendrik Sabert, Paulus Antonius Andreas Teunissen

Publication number: 20200390272Abstract: A beverage dispensing machine (2) has a housing that provides a receptacle for receiving an expandable cartridge (12) that is coupled into the machine so that it can receive a charge of water. A kneading system (40) is provided to act on the cartridge within the receptacle. The kneading system is activated after water has been allowed to enter the cartridge and mechanically acts on or from the exterior of the cartridge in order to compress and release regions of the cartridge in order to create vigorous agitation to move the contents of the cartridge around inside the main compartment and bring them into close contact with a charge of water from the supply. Such a machine allows a wide variety of beverages to be created conveniently on demand from freeze-dried ingredients that can be stored inside the cartridges with a long shelf life.Type: ApplicationFiled: August 18, 2020Publication date: December 17, 2020Applicant: Zendegii Ltd.Inventors: Khosro Ezaz-Nikpay, Daniel Kohn, Hendrik Sabert, Hiromi Sasaki, Aurelie Schmitt
