Patent number: 8251103Abstract: A papermaking forming fabric includes: a set of top MD yarns; a set of top CMD yarns interwoven with the top MD yarns to form a top fabric layer; a set of bottom MD yarns; a set of bottom CMD yarns interwoven with the bottom MD yarns to form a bottom fabric layer; and a set of binding yarns that interweaves with and binds together the top and bottom fabric layers. The fabric has a Channel Factor (CF) of greater than 2.0, the CF being defined in Equation (1) as: CF=(PSMW/PSML)×(SOA % PS/SOA % RS)??(1) wherein: PSMW=the CMD width of an interstice between adjacent top MD yarns; PSML=the MD width of an interstice between adjacent top CMD yarns; SOA % PS=surface open area in the top fabric layer; and SOA % RS=surface open area in the bottom fabric layer.Type: GrantFiled: October 29, 2010Date of Patent: August 28, 2012Assignee: Weavexx CorporationInventor: Oliver Baumann

Patent number: 8038296Abstract: An optical observation instrument, in particular a spectacle, a reading aid or a telescope, comprises an optical element, in particular a spectacle lens, adapted to be controllably adjustable in its refractive power, a sensor, and a control unit for adjusting the refractive power as a function of signals from the sensor. The sensor is a brightness sensor. In a method of controllably adjusting a refractive power of an optical element in an optical observation instrument an optical parameter is captured by means of a sensor and the refractive power is adjusted as a function of a signal from the sensor. By means of the sensor the brightness of the light impinging on the optical instrument is captured.Type: GrantFiled: March 14, 2008Date of Patent: October 18, 2011Assignee: Carl Zeiss Vision GmbHInventors: Oliver Baumann, Jesús Miguel Cabeza Guillén, Michael Claus, Markus Haidl, Gerhard Kelch, Timo Kratzer, Herbert Krug, Peter Schnitzer, Hexin Wang

Publication number: 20100314064Abstract: A sieve for the wet-end section of a paper machine is described, in which the sieve has been compressed by at least one of increased temperature, pressure and/or moisture. Such a treatment leads to a sieve which has at least one side wherein the thread floats and knuckles are reshaped and the sieve presents at least one substantially flatter surface for the production of paper. This process does not cause any physical damage to the surface of the sieve, as current techniques of abrasively polishing the surface do, and therefore leads to cloths with improved properties and lifetimes.Type: ApplicationFiled: April 20, 2010Publication date: December 16, 2010Inventors: Joachim Pitzler, Oliver Baumann

Patent number: 7533991Abstract: The present invention is directed to an arrangement and a method for eye examination and/or for determining biometric eye data in which the movement of the eyes is compensated through the use of an eye tracker unit. The arrangement comprises a controllable digital illumination unit and an observation system which are arranged on separate supporting arms. A central control unit has connections to an image recording unit, an optical imaging system, an eye tracker unit and an output unit. Further, transmitter elements and/or actuating drives are provided at the separate supporting arms, at the zoom system and at the magnification changer. The examination can be adapted in an optimal manner to the task at hand by means of the structured illumination patterns that can be generated in a variable manner. Detection of all adjusting parameters relevant for recording can be used for calculations and for reconstructing the pertinent observation conditions. In case of repeated examinations for determining changes, e.g.Type: GrantFiled: November 13, 2003Date of Patent: May 19, 2009Assignee: Carl Zeiss Meditec AGInventors: Oliver Baumann, Michael Claus, Axel Doering, Ingo Koschmieder, Thomas Schulze, Bernd Spruck

Patent number: 7413305Abstract: An arrangement and method for positioning an ophthalmologic device with respect to the patient's eye to be examined in x-, y- and/or z-coordinates. The device includes a controllable illumination unit, an observation system, an image recording unit, a central control unit, an output unit, an eye tracker unit, and a device for relative positioning. The imaging system of the eye tracker unit has at least two different adjustable magnifications. In positioning the ophthalmologic device, the signal of the eye tracker unit is used to track a measuring mark and/or grid structure projected on the eye, and also to detect the position of the patient's eye with respect to the optical axis of the ophthalmologic device. The inventive solution makes it possible to automatically position the entire device with respect to the eye to be examined, thus simplifying examination and accelerating determination of biometric data.Type: GrantFiled: October 28, 2003Date of Patent: August 19, 2008Assignee: Carl Zeiss Meditec AGInventors: Oliver Baumann, Michael Claus, Axel Doering, Ingo Koschmieder, Thomas Schulze, Bernd Spruck

Patent number: 7330313Abstract: A telescope has at least one barrel. At least three optical elements, namely an objective lens, an inverting system, and an eyepiece are arranged within the barrel along a longitudinal axis thereof one behind another. Further, shaking movements of the barrel are compensated for by moving at least one of the optical elements relative to the barrel. The objective lens is rigidly connected to the barrel. The inverting system together with the eyepiece constitutes a common assembly. At least a part of the assembly is adapted to be moved relative to the longitudinal axis. As an alternative, the inverting system and the eyepiece are rigidly connected to the barrel and at least a part of the objective lens is adapted to be moved relative to the longitudinal axis.Type: GrantFiled: June 7, 2006Date of Patent: February 12, 2008Assignee: Hensoldt AGInventors: Oliver Baumann, Klaus Felgenhauer, Stefan Gerth, Klaus Knupfer, Walter J.
