  • Patent number: 9335333
    Abstract: A test tape cassette is disclosed that includes a cassette housing and an analytical test tape. The test tape includes a plurality of analytical test elements, a spreading fabric for applying a body fluid, and an underlying reagent layer for detecting an analyte in the body fluid. The cassette housing has an application tip that has a guide path extending longitudinally to the test tape in an arched-shape and is uncurved at right angles thereto for supporting the test tape in a kink-free manner. The guide path has an apex area with a central opening that delimits a measuring window for an optical measurement on the test elements.

  • Patent number: 8137980
    Abstract: The invention concerns a reagent system for the so-called on-board control of analytical elements, in particular test strips, containing an organic N-oxide or a nitroso compound. The invention also concerns analytical elements containing a reagent system for a detection reaction and a reagent system for an on-board control. Furthermore, the invention concerns a method for checking analytical elements in which a reagent system for an on-board control is examined optically or electrochemically with the aid of a measuring instrument for changes which could indicate a stress of the analytical element.

  • Patent number: 7635834
    Abstract: Systems and method for optically imaging objects and in particular optical patterns or codes onto a detection device by a pinhole aperture are described. According to an embodiment of the invention these systems have optical attenuation elements between the illumination devices and the object which substantially compensate the system-inherent imaging detects caused by the pinhole aperture and in particular the system-inherent peripheral decrease in brightness of an image of the object formed by a pinhole aperture on the detection device. According to an embodiment of the invention, the optical attenuation elements change the illumination intensity of the object in such a manner that the central areas of the object are illuminated at a lower light intensity than its peripheral areas. As a result of the subsequent imaging of the object by a pinhole aperture, the central areas of the object are imaged onto the detection device at a higher light intensity than the peripheral areas of the object.
