Dieter Ruehle 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).

  • Automated clinical analyzer reagent formulation
    Patent number: 7338804
    Abstract: This invention significantly reduces the frequency of hydraulic failure in the analytical line of a capsule chemistry sample liquid analysis system which can occur when the reagents required for the specific analytical test have an imperfect merger with the sample aliquot reagent in the vanish zone of the analytical line. It has been found that the dynamic surface tension of the sample aliquot reagent and the analytical reagent influence the merging process. It has also been found that optimum merging of these reagent capsules in the vanish zone can be obtained when the dynamic surface tension of the sample aliquot reagent and analytical reagent is different.

  • Ultraphobic surface
    Patent number: 7285331
    Abstract: The invention relates to a structured surface with ultraphobic properties. Said surface as a surface topography in which the value of the integral of a function S: S(log f)=a(f)·f, which gives a relationship between the spatial frequencies f of the individual Fourier components and their amplitudes a(f) is at least 0.5 between the integration limits log (f1/?m?1)=?3 and log (f2/?m?1)=3. The surface consists of a hydrophobic or oleophobic material or is coated with a hydrophobic or oleophobic material.

  • Method and device for moving and placing liquid drops in a controlled manner
    Patent number: 7214302
    Abstract: The invention relates to a method and a device which serves for moving and dosing amounts of liquid on a microscopic scale with a volume of especially 10?12 to 10?6 liters by means of an inhomogeneous electric field using a support having an ultraphobic surface.
