Patent number: 9631229Abstract: With respect to molecular biology, medicine, and biotechnology, provided is a method related to the performance of Polymerase Chain Reaction. The method includes using the device for identification of nucleic acids containing a microchip with at least one reaction zone on its surface. The microchip contains a heat-conducting substrate made of aluminum while each reaction zone is separated from the heat-conducting substrate by a layer of the passivating material covalently bound to the surface of the heat-conducting substrate while over the layer of the passivating material one or several dried components of the polymerase chain reaction is placed. In this method the ratio of the aggregate thermal mass of the microchip to thermal conductance of the microchip substrate does not exceeding 0.04 s. The technical result is reduced duration of the analysis, higher reliability, accuracy, efficiency and cost-effectiveness of the analysis.Type: GrantFiled: October 8, 2009Date of Patent: April 25, 2017Assignee: Lumex Instruments LimitedInventors: Alexander Anatolevich Stroganov, Maxim Nikolaevich Slyadnev

Patent number: 8467614Abstract: The present invention provides a method for an Optical Character Recognition (OCR) system providing recognition of characters that are partly hidden by crossing outs due to for example an imprint of a stamp, handwritten signatures, etc. The method establishes a set of template images of certainly recognized characters from the image of the text being processed by the OCR system, wherein the effect of the crossed out section is modelled into the template images before comparing these images with the image of a visually impaired crossed out character. The modelled template image having the highest similarity with the visually impaired crossed out character is the correct identification for the visually impaired character instance.Type: GrantFiled: November 21, 2008Date of Patent: June 18, 2013Assignee: Lumex ASInventors: Knut Tharald Fosseide, Hans Christian Meyer

Patent number: 8358409Abstract: The invention relates to analytical chemistry. In the analyser, mercury placed in a spectral lamp is enriched with a mercury isotope having an even neutron number, wherein said isotope constitutes not less than 50% of the total mercury content in the spectral lamp. Moreover, the discharge cavity of the spectral lamp is connected to a ballast cavity, the volume of which is greater than the discharge cavity volume, and electrical discharge generating means, the discharge cavity and the ballast cavity are designed in such a way that the discharge generated in the discharge cavity does not penetrates into the ballast cavity. A buffer gas in the spectral lamp contains a noble gas in a quantity equal to or greater than 50%, the charge of the atomic core of said gas being not less than 36. Said invention makes it possible to lower the detection level of mercury in a carrier gas and to reduce a drift.Type: GrantFiled: May 18, 2009Date of Patent: January 22, 2013Assignee: Lumex Instruments LimitedInventor: Sergey Evgenyevich Sholupov

Patent number: 8320677Abstract: The present invention is related to a method of processing of output data from an Optical Character Recognition (OCR) system, wherein the output data comprises images of double printed characters. The method identifies the respective members of a suspected double printed character image by first providing a set of single character template images from images of characters identified in the text being processed by the OCR system, then combining the single character templates providing candidate models for the suspected double printed character image. Correlation between each respective candidate model and the suspected double printed character image provides an indication of which pair of modelled single template character images that most probable are the correct identification of the respective character images in the double printed character image.Type: GrantFiled: November 24, 2008Date of Patent: November 27, 2012Assignee: Lumex ASInventors: Knut Tharald Fosseide, Hans Christian Meyer

Patent number: 8208736Abstract: A method and system for recognizing text in computer images comprising distorted text provides an adaptive iterative process wherein recognition rules are adapted, added or omitted based on the present state of the recognition process. When the first pass through the recognition and adaptation is completed, the remaining unrecognized words (15) are passed through the recognition system 1 using the modified set of recognition rules stored in (18) and the process is repeated. In most cases the recognition system 1 will identify further reliable recognized words, which iteratively can be used to improve the recognition rules until the true text comprised in image (10) is recognized throughout the whole text. The steps of the method according to the present invention are thus repeated until convergence.Type: GrantFiled: March 13, 2006Date of Patent: June 26, 2012Assignee: Lumex ASInventors: Hans Christian Meyer, Mats Stefan Carlin, Knut Tharald Fosseide
