  • Publication number: 20220104736
    Abstract: A method of determining concentration of an analyte in a body fluid using a mobile device having a camera is disclosed. In the inventive method, the camera is used to take a series of calibration images of a region of interest of an object. The calibration images differ in their brightness. A key calibration figure is derived from each calibration image, the key calibration images being characteristic for a tone mapping function of the mobile device. A probable tone mapping function of the mobile device is determined by taking into account the key calibration figures. An analysis image is taken of at least part of a test field of an optical test strip, the test field having a body fluid applied thereto. Analyte concentration is determined from the analysis image of the test field by taking into account the probable tone mapping function of the mobile device.

  • Publication number: 20210131973
    Abstract: A method for detecting an analyte in a sample is disclosed. The method includes providing a mobile device having a camera and an illumination source. A test strip having a test field with at least one test chemical for performing an optical detection reaction in the presence of the analyte is provided. The sample is applied to the test field. Several images of a region of the test strip are captured. The region includes at least part of the test field to which sample is applied. The images are captured before and after the sample is applied and with the illumination source turned on and off. The images captured are compared and differences in light intensities are determined. Analyte concentration is determined using the images captured and the determined light intensities.

  • Patent number: 8559479
    Abstract: The invention relates to a method for the production of a photon pair source, which generates entangled photon pairs, having at least one quantum dot, wherein in the method the operational behaviour of the photon pair source is determined by adjusting the fine structure splitting of the excitonic energy level of the at least one quantum dot. It is provided according to the invention for the fine structure splitting of the excitonic energy level to be adjusted by depositing the at least one quantum dot on a {111} crystal surface of a semiconductor substrate.
