Patents by Inventor Aleksandr Komelkov

Aleksandr Komelkov 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).

  • Quantitative X-ray analysis—multi optical path instrument
    Patent number: 9739730
    Abstract: Apparatus includes an X-ray source 10, a wavelength dispersive X-ray detector for measuring X-ray fluorescence (XRF) and an energy dispersive X-ray detector 14 again for measuring X-ray fluorescence. Selected elements are measured using the wavelength dispersive process to reduce the overall measurement time compared with using only one of the two detectors or compared to a simple approach of measuring low atomic number elements with the wavelength dispersive detector and high atomic number elements with the energy dispersive detector. The selection can take place dynamically, in particular on the basis of the results of the energy-dispersive detector.
    Type: Grant
