Patents by Inventor Ralf TORGRIP

Ralf TORGRIP 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: 10197513
    Abstract: A method and apparatus for estimating a heating value of a biological material. The method includes irradiating of the biological material with X-ray radiation of at least two different energy levels, measuring of an amount of radiation transmitted through the biological material at these energy levels, and measuring fluorescent radiation emitted by the biological material when irradiated at these energy levels. A final estimate of the heating value is then determined based on a preliminary estimate of the heating value of the biological material based on the measured transmitted radiation and a correction value based on the fluorescent radiation.
    Type: Grant

  • Patent number: 9588065
    Abstract: A method and apparatus for determining the concentration of a specific analyte in a sample of biological material are disclosed. The sample is placed in a sample container (10) which provides at least two radiation paths (14) with different lengths through the sample container (10), and is sequentially irradiated with electromagnetic radiation, e.g. X-rays. The amount of radiation penetrating the sample is detected, and absorbance is determined based on the detected radiation. During irradiation, the sample container (10) is moved in relation to the radiation source (1) and detector (5) so that absorbance measurements at different path-lengths are acquired. A regression line from the absorbance values and path lengths is determined, such that a slope of the regression line is obtained, and based on this slope, the concentration of the specific analyte is determined.
