  • Publication number: 20210181093
    Abstract: The invention relates to a method for identifying one or more spectral features in a spectrum (4, 5) of a sample for a constituent analysis of the sample, comprising providing the spectrum (4, 5), predefining an approximation function (6), which is a continuously differentiable mathematical function, respectively forming an (n?1)-th order derivative (7, 8, 9) of the spectrum (4, 5) and of the approximation function (6), wherein the number n>1, generating a correlation matrix (10) from the two (n?1)-th order derivatives (7, 8, 9), and respectively identifying the spectral feature or one of the spectral features in each case as a function of a local extremum (i) of the correlation matrix (10) for at least one extremum (i) of the correlation matrix (10) in order to simplify the constituent analysis of the sample.

  • Publication number: 20200388042
    Abstract: The invention relates to a method and a device for determining at least one mechanical property of at least one object, wherein the at least one object is subjected to at least one interaction which influences a movement state of the at least one object, wherein the at least one interaction is selected such that the movement state effectuated by the interaction is a function of the at least one mechanical property, wherein the at least one object is observed using at least one camera, wherein the movement state is determined from images recorded by the at least one camera and wherein the at least one mechanical property of the at least one object is determined from the movement state thus determined.

  • Publication number: 20200360970
    Abstract: The invention relates to a method and to a device for sorting particles of a material flow into at least two fractions, the particles in the material flow being observed by means of at least one detector, particles being subjected to acoustic pressure on the basis of the properties determined by the detector so that they are supplied to different fractions.

  • Publication number: 20200096442
    Abstract: A system is provided for detecting non-metallic, non-aqueous substances in an aqueous sample, comprising a transmitter section, which emits electromagnetic radiation in the terahertz range towards the sample, a receiver section, which detects radiation components of said electromagnetic radiation which are modified by the sample and/or the substances therein and an evaluation section, which evaluates radiation components which are detected by the receiver section in order to establish whether non-metallic, non-aqueous substances are present or not in the aqueous sample, a transition of the aqueous sample from the liquid aggregate state into the solid aggregate state or vice versa taking place, radiation components which are modified respectively, for a plurality of different states of the aqueous sample, during this transition being detected by means of the receiver section, and the radiation components thus detected being evaluated by means of the evaluation section.

  • Patent number: 10491788
    Abstract: The invention relates to an apparatus for controlling the quality of transparent objects, comprising at least one light source being adapted to illuminate the object, and at least one image capturing device, by means of which at least one image of the object can be detected, wherein the apparatus comprises further at least one reflector, wherein the reflector and the image capturing device define a beam path, wherein the reflector, the image capturing device, and the light source are arranged such that the object can be arranged between the reflector, on the one hand, and the image capturing device and the light source, on the other hand, such that a single sheet of material is located in the beam path. Furthermore, the invention relates to a corresponding method for controlling the quality of transparent objects.
