Frans Ejner Ravn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10254223
    Abstract: According to an embodiment of the invention, an apparatus to detect fluorescence from a sample is disclosed. The apparatus comprises a sample plane onto which the sample is arranged, an excitation light unit including at least a light source to illuminate the sample, and a detection unit comprising at least a detector having at least 100,000 active detection elements to detect a fluorescence signal from the sample.
    Type: Grant
    Filed: January 25, 2018
    Date of Patent: April 9, 2019
    Assignee: ChemoMetec A/S
    Inventors: Søren Kjaerulff, Mette Elena Skinderso, Helle Frobose Sorensen, Frans Ejner Ravn, Martin Glensbjerg

  • Patent number: 9224031
    Abstract: The invention relates to image analysis of dark field images obtained at low magnification below 10:1. Image analysis of dark field images obtained at low magnification can be combined with analyzes of images obtained in respect of the same section of a sample and same magnification but with other techniques such as fluorescent microscopy. The system and method can be used e.g. for particle counting, particle size measurement, particle size distribution, morphology measurement, where the particles can be cells and/or cell parts. The invention also relates to a compact dark field light source unit, a system or apparatus including a microscope which by itself is compact and comprises the mentioned dark field light source unit.
