Patents by Inventor Aleksandar Crnatovic

Aleksandar Crnatovic 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: 9541525
    Abstract: A system and methodology for the detection of threat substances is described. The detector system consists of a method to evaporate the sample into a primary separator and thermal release of trapped target materials into a secondary separator like conventional GC. The GC column is thermally ramped to elute all substances and the end of the column terminates into an atmospheric pressure chemical ionization source of an axial ion mobility spectrometer (AIMS). Both polarity ions are pulsed into a single construction separator tube at different timing. Their arrival time is detected on a collector plate, which allows registering their ion mobility spectra of both polarities for a single GC peak.
    Type: Grant

  • Publication number: 20030059101
    Abstract: A method for inspecting a display panel includes capturing images of a portion of a plurality of display panels having display elements with an image acquisition device having sensor elements, each image comprising an image of approximately a first number of display elements captured with approximately a second number of sensor elements, the first number different from the second number, each image including a Moiré artifact pattern, combining the images of the portion of the plurality of display panels to form a reference image including a Moiré artifact pattern reference, capturing a sample image of a portion of a sample display panel having display elements with the image acquisition device, the sample image comprising an image of approximately the first number of display elements on the sample display captured with approximately the second number of sensor elements, the sample image including a sample Moiré artifact pattern, combining the sample image with the reference image to inhib
