  • Patent number: 11155285
    Abstract: An optical system (100) for a light emitting diode (LED) signal includes a plurality of light emitting diodes (LEDs) (12, 14), a plurality of optical lenses (20, 40, 60, 80) for diverging and collimating light generated by the plurality of LEDs (12, 14), wherein the plurality of LEDs (12, 14) and the plurality of optical lenses (20, 40, 60, 80) are sequentially arranged in an axial direction, and wherein the plurality of optical lenses (20, 40, 60, 80) are configured such that by altering an axial position of one of the optical lenses (20, 40, 60, 80) from a first defined axial position to a second defined axial position, a final angular light distribution of the optical system (100) is variable.

  • Publication number: 20210285888
    Abstract: A method of determining analyte concentration in a body fluid with a mobile device having a camera. A user is prompted to apply body fluid to an optical test strip and then waits a predetermined minimum waiting time. The camera captures an image of part of the test field having the body fluid applied thereto. Analyte concentration is determined based on the image captured. The determination includes estimating a point in time of sample application to the test field by taking into account time-dependent information derived from the image captured using a first color channel of a color space. The determination also estimates the concentration of the analyte by taking into account concentration-dependent information derived from the image using a second color channel of the color space.

  • 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.

  • Publication number: 20210088506
    Abstract: A method of evaluating suitability of lighting conditions for detecting an analyte in a sample using a mobile device camera. A test strip is provided for detecting the analyte. A first image of the test strip is captured while an illumination source of the mobile device is turned off and a second image of the test strip is captured while the illumination source is turned on. A sample is applied to the test strip and the first and second images are compared to thereby determine the difference in lighting conditions between the first image and the second image. The comparison is used to derive information on suitability of the lighting conditions for analyte detection. The lighting conditions are indicated as suitable when a predetermined threshold amount of light intensity used for illumination of the test strip originates from the illumination source.

  • Patent number: 9171488
    Abstract: A display element and a display device in which the display element is mounted. The display may be a variable message sign. The sign includes a tube-like housing in which lenses and apertures can be disposed. The light exiting a light source is emitted via an emitting surface, by way of which an illuminated traffic sign results from interacting with further display elements. The light source and the optical elements are disposed at different heights in the horizontally oriented housing. The optical axes can thereby extend horizontally, or the optical elements can lie on a main axis which is tilted downward in an radiation direction. In both cases, sunlight impinging from above at an angle advantageously falls on the LED to a slight degree, by way of which the phantom light phenomenon is minimized.
