Patent number: 10775503Abstract: A measuring method and a distance measuring device for determining an absolute distance to a target moving at a radial movement velocity with respect to the distance measuring device, wherein a modulated transmission radiation is emitted to the target and a measurement signal is detected, such that information regarding the absolute distance to the target is attached to the measurement signal by means of at least one reference point of a frequency-dependent signal profile of the measurement signal, on the basis of a modulation phase of the reception radiation with respect to a set fundamental modulation, wherein for a set fundamental modulation frequency the deviation of said frequency value with respect to a reference point, in particular a minimum point, of the signal profile of the measurement signal is derived, namely the frequency offset and the offset direction with respect to the reference point.Type: GrantFiled: April 11, 2018Date of Patent: September 15, 2020Assignee: LEICA GEOSYSTEMS AGInventors: Konrad Wildi, Thomas Lüthi, Hans-Ulrich Minder

Publication number: 20180299249Abstract: A method and a measuring appliance for measuring a distance by means of interferometry, by means of a measurement radiation and a reference radiation that is frequency-shifted relative thereto, produced by a frequency shifter that is actuated by a carrier signal, wherein, within the scope of deriving the distance measurement, a system clock is decoupled from a reference counter for capturing a carrier frequency of the carrier signal and care is taken that the system clock and the reference clock are as different as possible in order to obtain phase information and thereby achieve an improvement in the resolution.Type: ApplicationFiled: April 13, 2018Publication date: October 18, 2018Applicant: LEICA GEOSYSTEMS AGInventor: Konrad WILDI

Patent number: 9720087Abstract: The invention relates to a method for determining a spatial orientation of an auxiliary measurement object for a laser tracker, said measurement object having reference features which provide points of light. The tracker has a base, a support which can be pivoted in a motorized manner, a pivoting unit which can be rotated about a tilting axis in a motorized manner and which comprises an image capturing unit for capturing an image of the points of light, and a beam source for emitting a laser beam. According to the method, an image is captured in the direction of the auxiliary measurement object with respective capturable points of light, and the spatial orientation of the auxiliary measurement object is derived from image positions in the image for the points of light captured in the image using an image analysis.Type: GrantFiled: October 29, 2013Date of Patent: August 1, 2017Assignee: LEICA GEOSYSTEMS AGInventors: Andreas Christen, Konrad Wildi, Albert Markendorf

Patent number: 7978868Abstract: In one embodiment, an apparatus for processing sound includes a means (401) for analyzing a sound signal into a number of frequency bands and a means (403) for applying variable gain to each frequency band independently. Gain in applied under control of a number of gain comparator means (409) each of which generates a number of statistical distribution estimates in respect of each signal and compares those estimates to predetermined hearing response parameters stored in memory (411). The numerous gain compensated frequency bands are then combined (415) in order to generate a single sound signal. The apparatus may be implemented in dedicated hardware embodiment or by software running on a microprocessor.Type: GrantFiled: February 5, 2008Date of Patent: July 12, 2011Assignee: Cochlear LimitedInventors: Peter Blamey, Christopher John James, Hugh J. Mcdermott, Lois Martin, Konrad Wildi
