20140332747 | MEMRISTOR BASED ON A MIXED METAL OXIDE - The present invention relates to micro- and nano-electronics devices based on non-conventional materials. Such memristor devices with stable and reproducible characteristics can be used in the production of computer systems based on the analog architecture of artificial neural networks. The device in question consists of an active layer situated between two current conducting layers with which it is in electrical contact, said active layer being an ABOx-type oxide, where element B is titanium or zirconium or hafuium, and element A is a trivalent metal with an ion radius equal to 0.7-1.2 of the ion radius of titanium or zirconium or hafuium. If element B is titanium, then element A is selected from aluminium or scandium; if element B is zirconium or hafuium, then element A is selected from scandium or yttrium or luteciurn. The technical result of the proposed invention is an increase in the stability and reproducibility of the switching voltage and of the resistance in low and high impedance states. | 11-13-2014 |

20130142446 | SCALABLE COMPRESSION USING JPEGT-LS - A global bit stream comprising at least a first and a second bit stream is generated using an original visual bit stream. The first bit stream is generated by compressing the original visual bit stream using a JPEG-LS compression technique with a lossy factor ānā. The second bit stream is generated by compressing a difference bit stream using a JPEG-LS lossless compression technique, wherein the difference bit stream comprises a difference between the original visual bit stream and the first bit stream. The visual display is recreated using a reconstructed bit stream after receiving the global bit stream over a channel, wherein the reconstructed bit stream is generated by decompressing at least the first bit stream using a JPEG-LS lossless compression technique. The second bit stream is decompressed using JPEG-LS lossless compression technique and the quality of the display may be enhanced by adding the decompressed second bit stream. | 06-06-2013 |
