Publication number: 20230154450Abstract: A process labeled “voice grafting” can be understood in terms of the source-filter model of speech production as follows: For a patient who has partially or completely lost the ability to phonate, but retained at least a partial ability to articulate, the techniques described herein computationally “graft” the patient's time varying filter function, i.e. articulation, onto a source function, i.e. phonation, which is based on the speech output of one or more healthy speakers, in order to synthesize natural sounding speech in real time.Type: ApplicationFiled: April 20, 2021Publication date: May 18, 2023Inventor: Rudolf MURAI VON BÜNAU

Publication number: 20210145278Abstract: The proposed combination device combines any tonometric metrology with a drug application to administer glaucoma medication on an eye. Several technical concepts are proposed and exemplary embodiments for rebound tonometry and air-puff tonometry are shown. However other methods such as optical coherence elastography (OCE) could also be used. The Solutions provide home care tonometry offerings which host the capability to administer glaucoma medication.Type: ApplicationFiled: April 29, 2019Publication date: May 20, 2021Inventors: Rudolf Murai VON BÜNAU, Johannes KINDT, Martin HACKER, Tobias BÜHREN, Thomas K.

Publication number: 20210015665Abstract: A drainage aid which is introduced into tissue to permit or improve drainage of liquid by generating new drainage channels or by keeping existing drainage channels open, to permit effective drainage. In particular, a stent for glaucoma treatment is provided for the drainage of aqueous humor from the anterior chamber through the cornea, the limbus or the sclera directly onto the eye surface. The shunt implant includes at least one inner component and one outer component, which are connected to each other following introduction. The cross section of the shunt implant can be round, oval or angular. The invention can also be used wherever narrowed vessels or channels are intended to be expanded or held open.Type: ApplicationFiled: March 6, 2019Publication date: January 21, 2021Applicant: Carl Zeiss Meditec AGInventors: Martin HACKER, Rudolf Murai von Bünau, Christian DIETRICH

Patent number: 10194797Abstract: A method for selecting an intraocular lens (IOL) to be implanted into an eye, in which the selection is based on a non-paraxial approach. In a ray tracing method for selecting an intraocular lens to be implanted into an eye with a simplified, centered optical system, in addition to the preoperatively measured biometric values, the effective lens position of the corresponding eye and the optical transfer function of the IOLs are used, which are calculated for a standardized distance behind the equatorial plane of the IOL. The method may be used to select an intraocular lens to be implanted into an eye and is equally suitable for spherical, aspherical, toric and multifocal IOLs.Type: GrantFiled: May 27, 2016Date of Patent: February 5, 2019Assignee: Carl Zeiss Meditec AGInventors: Rudolf Murai von Bünau, Tobias Bühren

Patent number: 9462938Abstract: For the pre-operative calculation of the power of an intraocular lens, three input parameters are needed: the axial length of the eye (AL), the refractive power of the cornea, and the distance between the front of the cornea and the back focal plane of the intraocular lens, the so-called effective lens position (ELP). The invention shows a novel approach to the determination of the ELP.Type: GrantFiled: August 25, 2015Date of Patent: October 11, 2016Assignee: Carl Zeiss Meditec AGInventors: Rudolf Murai Von Bünau, Burkhard Wagner, Scott A.

Patent number: 8801184Abstract: A system for the improved imaging of eye structures based on optical coherence tomography. The system includes an interferometric measuring arrangement, which has an optical element arranged in the measurement arm or reference arm for influencing the polarization state of the light before the light is interferometrically superimposed, a scanning unit arranged in the measurement arm for implementing OCT scans, a detector for recording the produced interference pattern, and an evaluating and documenting unit. At least two different polarization states of the light are produced. The interference patterns produced in the interferometric measuring arrangement are recorded and forwarded to the evaluating and documenting unit which reconstructs OCT scans from the transmitted interference patterns, combines the OCT scans, and presents and/or stores the resulting OCT signals. The system can be used for pachymetry in addition to the pre- and post-operative imaging for analysis and measurement.Type: GrantFiled: April 23, 2011Date of Patent: August 12, 2014Assignee: Carl Zeiss Meditec AGInventors: Martin Hacker, Rudolf Murai von Bünau, Burkhard Wagner

Publication number: 20100302550Abstract: An optical time domain coherence tomograph including an object beam path, a detection beam path and a detector unit. An interferometer unit, which has a first and a second beam path part having different optical path lengths, splits radiation and feeds it into the two beam path parts and superimposes it again after passage through the beam path parts and thus generates a dual beam, which has components which are axially offset to one another because of the differing optical path lengths of the two beam path parts. A scanning unit has a first adjuster and a second adjuster for adjusting the optical path length of the first and second beam path parts and the first and the second adjustment means adjusting the path length for scanning the object in coordination to one another under control by the control unit.Type: ApplicationFiled: May 27, 2010Publication date: December 2, 2010Applicant: CARL ZEISS MEDITEC AGInventors: Martin HACKER, Roland BERGNER, Ingo KOSCHMIEDER, Rudolf Murai VON BÜNAU, Gerard ANTKOWIAK, Ralf EBERSBACH, Thomas PABST

Patent number: 5863712Abstract: The pattern forming method is capable of forming a projected image or photoresist pattern that is faithful to a designed pattern without performing complex correction of a mask pattern. A projection exposure system and a semiconductor device fabrication method employing this pattern forming method are also disclosed. Exposure is performed by setting a pupil filter with a variable amplitude transmittance to the pupil position of the projection lens of a projection exposure system. The pupil filter has a transparent substrate, a phase retarding layer, a translucent film, and an opaque stencil. The pupil filter is replaced or rotated during either a plurality of exposures or during a single exposure onto the same position on the surface of a wafer substrate that is to be exposed. It is possible to improve the fidelity of the contour of a pattern transferred image without improving the numerical aperture (NA) of a projection lens, decreasing the wavelength of exposure light, or locally correcting a mask pattern.Type: GrantFiled: January 6, 1997Date of Patent: January 26, 1999Assignee: Hitachi, Ltd.Inventors: Rudolf Murai Von Bunau, Hiroshi Fukuda

Patent number: 5715039Abstract: In exposing and projecting a mask onto a substrate using projection optics, a first grating is provided between the substrate and the projection optics and a second grating is provided between the projection optics and the mask so that the image of the mask pattern is formed near the substrate surface by the interference of beams diffracted by the first grating. This arrangement produces the effect of virtually increasing the NA of the optical system by up to a factor of two, making it possible to manufacture LSIs with fine patterns.Type: GrantFiled: May 17, 1996Date of Patent: February 3, 1998Assignee: Hitachi, Ltd.Inventors: Hiroshi Fukuda, Rudolf Murai von Bunau
