  • Patent number: 11599738
    Abstract: Method for examining a multiplicity of distributed objects (1) by using an overview image (200) of the area (2) in which the objects (1) are distributed, wherein the overview image (200) is converted (110) into a binary image (210) by virtue of the intensity values (202) of the pixels (201) of the overview image (200) being classified (202a, 202b) as to whether they are on the near or far side of a prescribed threshold (208); the binary image (210) is cleared (120) of structures (219) that are smaller than the objects (1), so that a cleared image (220) is produced; and the cleared image (220) is morphologically closed (130), so that a binary object mask (230) is produced that indicates which locations in the area (2) belong to objects (1) and which locations in the area (2) do not belong to an object.

  • Patent number: 11211762
    Abstract: The invention relates to an apparatus for generating laser pulses. It is an object of the invention to provide a method for generating synchronized laser pulse trains at variable wavelengths (e.g., for coherent Raman spectroscopy/microscopy), wherein the switching time for switching between different wavelengths should be in the sub-?s range. For this purpose the apparatus according to the invention comprises a pump laser (1), which emits pulsed laser radiation at a specified wavelength, an FDML laser (3), which emits continuous wave laser radiation at a cyclically variable wavelength, and a nonlinear conversion medium (4), in which the pulsed laser radiation of the pump laser (1) and the continuous wave laser radiation of the FDML laser (3) are superposed.

  • Patent number: 10962386
    Abstract: A magnetic revolution counter, and method for determining a predefinable number n of revolutions to be determined of a rotating magnetic field, generated by a magnetic system includes a revolution sensor, which includes magnetic domain wall conductors composed of open spirals or closed, multiply-wound loops, which are formed by a GMR layer stack or a soft magnetic layer comprising locally present TMR layer stacks and in which magnetic 180° domain walls can be introduced and located by measuring the electrical resistance of predefinable spiral or loop sections, wherein a single domain wall is, or at least two magnetic domain walls are, introduced into the domain wall conductors such that the at least two domain walls are brought into a defined separation of greater than 360° with respect to one another, based on the change in location thereof from a first to a second position, with a rotation of the outer magnetic field by the angle of greater than 360°, and are permanently thus spaced apart from one another,

  • Patent number: 10859404
    Abstract: A magnetic revolution counter for the self-identification of error states includes magnetic domain wall conductors which are composed of open spirals or closed, multiply-wound loops, formed by a GMR layer stack or a sort magnetic layer of locally present TMR layer stacks and in which the magnetic 180° domain walls can be introduced and located, wherein a predefinable bijective magnetization pattern of domain walls and/or domain wall gaps is written in, and the associated signal levels thereof are stored in the form of signal level sequences in a first memory in tabular form, which is compared to tabular target value patterns of the signal level sequences stored in a second memory for each permissible revolution i (0?i?n), and a third memory is provided, in which tabular error target value patterns of deviations of signal level sequences, caused thereby, from regular signal level sequences stored in the second memory are stored.

  • Patent number: 10769782
    Abstract: Exemplary method, computer-accessible medium and system can be provided for determining the presence or absence of a local and/or global property of a biological tissue sample. Thus, it is possible to obtain at least one image of the sample, search the image(s) for a presence of at least one particular feature that is contained in a pre-defined set of features, and assign, to the particular feature(s). It is possible to compute, with a computer processor, at least one discriminant value that is a function of the pronunciation index that is weighted with a particular weight. The weight of each pronunciation index is a measure for a relevance of the corresponding feature with respect to the property. It is possible to determine whether the property is present in at least one part of the biological tissue sample depending on whether the discriminant value exceeds a pre-defined threshold and/or and optimized threshold.

  • Patent number: 10228267
    Abstract: A magnetic sensor for the absolute counting of revolutions or linear distances includes a soft magnetic loop structure, which is populated with a predeterminable number of magnetic domains and provided with GMR or TMR layer assemblies, in which at least two separate coplanar loops having predominantly straight subsegments extending in a rhombus-like arrangement with respect to each other are provided, and the at least two loops are connected to each other via a shared intersecting point, wherein directly in front of each intersecting region in which, and after which, the domains can change from one loop to the neighboring loop, these sections of the loop structure are bent away from the conductor guidance and are curved in a siphon-like manner in this region so as to be directed into the interior of the loop structure, wherein the conductors in respective siphon-like troughs intersect each other perpendicularly.
