Patent application numberDescriptionPublished
20100172411HIGH DYNAMIC RANGE CODECS - A method for encoding high dynamic ränge (HDR) images involves providing a lower dynamic ränge (LDR) image, generating a prediction function for estimating the values for pixels in the HDR image based on the values of corresponding pixels in the LDR image, and obtaining a residual frame based on differences between the pixel values of the HDR image and estimated pixel values. The LDR image, prediction function and residual frame can all be encoded in data from which either the LDR image of HDR image can be recreated.07-08-2010

20090093371MEMBRANE ARRAYS AND METHODS OF MANUFACTURE - The invention relates to G protein-coupled receptor (GPCR) microarrays on porous substrates for structural or functional analyses of GPCRs, and methods of preparing porous substrate surfaces for receiving membranes that comprise GPCRs. In one embodiment, a GPCR microarray of the invention comprises a membrane adhered to an upper surface of a porous substrate, the membrane spanning across a plurality of pores on the porous substrate to form a plurality of cavities having sufficient geometry to permit entry of assay reagents into each cavity, thereby allowing access of assay reagents to both sides of GPCR in the membrane.04-09-2009

20110178175METHOD FOR PRODUCING MECHANICALLY ACTIVATED AMORPHOUS AND AMORPHOCRYSTALLINE COMPOUNDS OF GLUCONIC ACID CALCIUM SALT - The invention relates to the creation of mechanically activated amorphous and amorphocrystalline compounds and compositions of a gluconic acid calcium salt, pharmaceutical preparations based thereon, a method for producing same and use for treatment of a wide range of diseases caused by disorders of calcium metabolism in an organism. A concept of the invention, as being claimed and as set forth in the application, consists in that the crystalline gluconic acid calcium salt or its compound with excipients is treated in grinding activator devices either up to the input specific energy value of not greater than 10.4 kJ/g and achieving an amorphocrystalline state or up to the input specific energy value of no less than 10.5 kJ/g and achieving an amorphous state. The obtainable agents are assessed by means of X-ray diffraction, IR, NMR, EPR spectroscopy, mass- or chromato-mass-spectrometry, and a differential thermal analysis. The mechanically activated amorphous and amorphocrystalline compounds and compositions are used as an active principle for preparing pharmaceutical preparations used for therapeutic, therapeutic-preventive and hygienic purposes. The pharmaceutical preparations comprising a therapeutically effective amount of active ingredient are used perorally 1-6 times daily, in dosages of 0.2-6 g, a course of at least 1 month. The invention can be used in medical and food industries in the production of biologically active agents, therapeutic-prophylactic means, medicinals and in practical medicine in treatment of acute osseous, dental and other diseases related to disorders of calcium metabolism in the organism.07-21-2011
