Publication number: 20240115127Abstract: The system, method and device includes an optical coherence tomography (OCT) system switchable between single scan mode or multi-scan mode. This is achieved by use of multiple beam splitters to produce multiple OCT beams, but the system still uses a single light source, a single sample arm, and single reference arm to achieve a compact, more cost effective, system. Additionally presented is a spectral domain OCT system with a spectrometer having multiple grating, each providing a different depth and/or resolution imaging capability.Type: ApplicationFiled: September 29, 2023Publication date: April 11, 2024Applicant: Carl Zeiss Meditec, Inc.Inventors: Muzammil A. Arain, Sophie Kubach, Jochen Straub, Tilman Schmoll

Publication number: 20240108212Abstract: The eye imaging system for producing images with reduced speckle artifacts may comprise a laser diode for providing a beam of radiation to the eye; a detector for collecting light returning from the eye and generating output signals in response thereto, the detector having a sensor integration time; a driver circuit for applying a modulated drive signal to the laser diode, the modulated drive signal inducing a spectral broadening of the beam of radiation during the sensor integration time. The laser diode may be a single-mode laser designed to operate at a fixed current and wavelength. The drive signal may be modulated by shaping a drive current pulse. The drive signal may be modulated by imposing an RF modulation on a drive current pulse. The drive signal may be further modulated by shaping a drive current pulse.Type: ApplicationFiled: September 21, 2023Publication date: April 4, 2024Applicant: Carl Zeiss Meditec, Inc.Inventors: Conor Leahy, An-Dien Nguyen, Robert Sprowl, Jochen Straub, John Walker

Patent number: 11911103Abstract: A medical ophthalmic system uses a patient-specific face mask to establish a predefined alignment between the ophthalmic system and an eye of a patient. The patient-specific face mask may optionally provide a light proof enclosure for the eye. The face mask may be coupled directly to an ophthalmic device, or its housing/enclosure, of the ophthalmic system. The face mask may be 3D printed based on a 3D model of the patient's face.Type: GrantFiled: December 15, 2020Date of Patent: February 27, 2024Assignee: CARL ZEISS MEDITEC, INC.Inventors: Jochen Straub, Kabir M.

Patent number: 11584998Abstract: An electrolytic device and to a method for operating an electrolysis of water with at least one electrolysis cell, the electrolysis cell having an anode compartment having an anode and a cathode compartment having a cathode. The anode compartment is separated from the cathode compartment by a proton exchange membrane. The anode compartment is suitable for holding water and oxidising the water on the anode to form a first product including oxygen and the cathode compartment is suitable for holding water and reducing the water on the cathode to a second product including hydrogen. Furthermore, the electrolysis device includes a first gas precipitation device for precipitation of oxygen, the first gas precipitation device for carrying out a natural water circulation being arranged above the electrolysis cell.Type: GrantFiled: September 21, 2018Date of Patent: February 21, 2023Assignee: SIEMENS ENERGY GLOBAL GMBH & CO.

Patent number: 11499814Abstract: An optical coherence tomography (OCT) system (63) is used to inspect bonding points (66A, 66B, 66C) sandwiched between two materials (layers 62, 64 of e.g. displays). The OCT differentiates between a bonding point, e.g. a weld, and air gaps between the two materials. The bonding points are identified as breaks in the air gap between the materials. By extracting various physical characteristics of the bonding points and the gap between the two materials, the present system determines whether the bonding is faulty.Type: GrantFiled: June 12, 2019Date of Patent: November 15, 2022Assignees: CARL ZEISS AG, CARL ZEISS INDUSTRIAL METROLOGY LLC, CARL ZEISS MEDITEC, INC.Inventors: Michael Totzeck, Marcin B.

Publication number: 20220257111Abstract: Various techniques for providing a low-cost ophthalmic imaging system, such an OCT or fundus imagers are presented. Cost is reduced by using a K-minor as a scanning component. The K-mirror is positioned at a retina conjugate. A beam splitter is positioned at the pupil conjugate and may be used to provide pupil splitting functionality. The beam splitter's shape and area conform to the focal light footprint of an illumination source such that it spans only a fraction of a collection window. 2D FFT is applied to capture spectra for purposes of selectively removing complex conjugate components and for extracting patient pupil to system collection pupil alignment. Consequently, pupil alignment is achieved by use of captured OCT data without the need for additional pupil cameras.Type: ApplicationFiled: July 30, 2020Publication date: August 18, 2022Inventors: Yingjian WANG, Yuan LIU, Jochen STRAUB, Masha DARVISHZADEH VARCHEIE, Conor LEAHY

Publication number: 20220251718Abstract: An electrolysis cell with a cell frame and to a method for producing an electrolysis cell, wherein the cell frame has a stepped inner profile. The inner profile has at least one support surface for receiving a planar component in the cell frame, and the support surface has a recess for a seal. A seal is first placed in the recess, and a membrane-electrode unit, a first gas diffusion layer, and an electrically conductive top layer are then introduced into the cell frame. The cell frame is then rotated, and a second gas diffusion layer is applied. The electrolysis cell produced in this manner includes the cell frame with the seal and the different layers.Type: ApplicationFiled: June 10, 2020Publication date: August 11, 2022Applicant: Siemens Energy Global GmbH & Co.

Patent number: 11382503Abstract: The present invention is an OCT imaging system user interface for efficiently providing relevant image displays to the user. These displays are used during image acquisition to align patients and verify acquisition image quality. During image analysis, these displays indicate positional relationships between displayed data images, automatically display suspicious analysis, automatically display diagnostic data, simultaneously display similar data from multiple visits, improve access to archived data, and provide other improvements for efficient data presentation of relevant information.Type: GrantFiled: December 14, 2020Date of Patent: July 12, 2022Assignee: CARL ZEISS MEDITEC, INC.Inventors: Jochen Straub, Shahram Shawn Dastmalchi

Patent number: 11197605Abstract: Improved scanning ophthalmoscopes for scanning the retina of an eye are discussed in the present disclosure. One example scanning ophthalmoscope includes an uncollimated light source, a first scanning element, a second scanning element, a slit of a first aspherical mirror, and a second aspherical mirror. The uncollimated light source produces a beam of light to illuminate the retina. The beam of light is relayed from the first scanning element onto the second scanning element by the slit of the first aspherical mirror. The second aspherical mirror relays the beam of light from the second scanning element to the pupil of the eye.Type: GrantFiled: December 13, 2018Date of Patent: December 14, 2021Assignee: CARL ZEISS MEDITEC, INC.Inventors: Yue Qiu, Matthew Everett, Jochen Straub

Publication number: 20210369109Abstract: A low cost fundus camera uses LED light sources placed adjacent the camera's imaging stop, and thereby eliminates the need for optics for introducing the light source to the camera's optical path. Lens reflex in the pupil relay is avoided by using only reflective optics in the pupil relay. Reflex from the LEDs is mitigated by actuating each LED separately, one at a time, and capturing a separate image with each actuated LED. Reflex-free regions of each captured image are extracted and combined to create a composite, reflex-free image.Type: ApplicationFiled: September 24, 2019Publication date: December 2, 2021Inventors: Jochen STRAUB, Robert SPROWL, Yuan LIU, Matthew J.
