Suresh N. Mehta 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).

  • Patent number: 7692162
    Abstract: Images of two-dimensional chromatograms or other sample arrays are formed on a scanning instrument that utilizes a line of illumination light that sweeps the length of the array either by moving across the array or by the array moving relative to the light, in either case scanning the entire two-dimensional array with a unidirectional pass of the moving component. The use of a CCD equipped with time delay integration allows the instrument to form an enhanced image.
    Type: Grant

    Date of Patent: April 6, 2010
    Assignee: Bio-Rad Laboratories, Inc.

  • Patent number: 5879900
    Abstract: A method for the simultaneous and quantitative, flow cytometric analysis of nucleated red blood cells (NRBC), white blood cells (WBC), damaged white blood cells and a white blood cell subclass differential (WBC/Diff) is provided.

  • Patent number: 5812419
    Abstract: A method of performing a first analysis and a second analysis on a single blood sample obtained with a single blood draw from a patient with an automated analyzer includes the steps of supplying the single blood sample obtained with the single blood draw from the patient to the automated analyzer. A memory on the automated analyzer containing a software routine is automatically accessed. The software routine is useful to adapt an optical system on the automated analyzer to correspond to the first analysis and the second analysis. The optical system on the automated analyzer is automatically adapted with the software routine in real time to correspond to the first analysis. The first analysis is automatically performed with the automated analyzer. The optical system on the automated analyzer is automatically adapted with the software routine in real time to correspond to the second analysis. The second analysis is automatically performed with the automated analyzer.

  • Patent number: 5631730
    Abstract: A pseudo telecentric flow cytometric optical system for the simultaneous detection of several characteristics of particles suspended in a flowing medium. The system is made up of a flowcell through which the particles pass substantially one particle at a time, an optical system for directing light from a light source onto the flowing particles in the flowcell, a side angle optical collection system for receiving light from the flowing particles and for directing the light to one or more of a first set of detectors, and a forward angle collection system for receiving light from the flowing particles and for directing the light to one or more of a second set of detectors.

  • Patent number: 5529752
    Abstract: This invention encompasses a work station for conducting assays which comprises filtering assembly, a slide reading assembly, and a slide with a porous filter membrane wherein the slide has a means for aligning the slide within the filter assembly to filter reagents on predetermined portions of the porous filter membrane and also to position the slide in the slide reading assembly so that detection will occur in those same predetermined locations.

  • Patent number: 4147628
    Abstract: The disclosure is of an improved method and apparatus for separating blood into light, substantially liquid phase and its heavy, substantially cellular phase by centrifuging a blood filled container having disposed therein an inert, gel-like barrier material possessing a density intermediate between the two phases of the blood. The improvement comprises employing a constricted tubular container, the constriction being at the zone where it is calculated the gel-like barrier material will align during centrifugation.
