  • Patent number: 8583379
    Abstract: A device and method for determining a concentration of a biological target including capturing an image of a ticket that contains the biological target; extracting a region of interest from the captured image; detecting a target from the extracted region of interest; computing intensity of the target in the region of interest; and determining the concentration of the biological target according to the computed intensity.
    Type: Grant

  • Patent number: 8275179
    Abstract: An apparatus for capturing the image of a wet/moist fingerprint. The apparatus includes: a prism having an imaging plane on which a finger having valleys and ridges is place, a bottom plane parallel to the imaging plane and a reflective plane intercepting the imaging plane and intercepting the bottom plane at an angle ?; a light source for generating a light with an incident angle of approximately 0° with respect to a surface normal of the imaging plane; and a lens for capturing light reflected from the reflective plane. The apparatus further includes an image sensor for generating an image of the valleys and ridges of the finger, wherein the reflective plane is arranged in such a way to meet the equation of ?>45 +(arc sin (n1/n2))/2, where n1 is a refraction index of medium filled between the valleys of the finger and the imaging plane, and n2 is refraction index of the prism.
