20080231483 | BINARIZING METHOD AND DEVICE THEREOF - A binary coding and decoding method and apparatus for MVD (Motion Vector Difference) absolute values, includes: dividing symbols for MVD absolute values to be coded into a plurality of subsets according to probability distribution properties; assigning a binary codeword for each subset; assigning a binary codeword for each symbol in each subset; concatenating and outputting the binary codeword for each subset and the binary codeword for each symbol in the subset, as the binary coding result. At the decoding side, decoding operations are performed by using a principle corresponding to that at the coding side. In this manner, the invention makes full use of the source properties on one hand, and effectively prevents the codeword length from being too long on the other hand. It has been experimentally testified that a better compression effect may be achieved during arithmetic coding process and thus the image coding performance may be improved effectively. | 09-25-2008 |
20080240597 | METHOD AND APPARATUS FOR REALIZING ARITHMETIC CODING/DECODING - A method and apparatus for performing arithmetic encoding/decoding in an arithmetic encoder is disclosed. It comprises: firstly, when performing binary arithmetic encoding/decoding in the arithmetic encoder, an interval update process for arithmetic encoding/decoding to be performed in the original domain is mapped to the logarithm domain, and the interval update computation is implemented with direct add/subtract operations; during arithmetic encoding/decoding in the logarithm domain, data conversions between the original domain and the logarithm domain are performed by approximations; and after encoding/decoding a symbol, its probability is updated when necessary, the update being performed with add/subtract operations in the logarithm domain. It can be seen that with the arithmetic encoding/decoding solutions of the disclosure, the arithmetic encoding/decoding process and the probability estimation involved therein are mapped to the logarithm domain. Data conversions between the original domain and the logarithm domain are performed by means of approximation equations. Accordingly, complicated computations and table looking-up are avoided effectively. Therefore, the disclosure provides a simple, efficient and suitable solution for performing arithmetic encoding/decoding. | 10-02-2008 |
20110182748 | CENTRIFUGAL IMPELLER - A centrifugal impeller includes a body of antistatic plastic and a back plate made of metal, preferably aluminium. The back plate is fixed to the body is such a way that the back plate can not make accidental contact with a volute of a blower in which the impeller is deployed. | 07-28-2011 |
20120135647 | Connector - A connector comprises a base plate defining a first end and a second end along a longitudinal direction, a first connecting arm, a first end of which is connected with the second end of the base plate, and a second end of which is substantially extended upwards relative to the first end thereof, a contact arm, a first end of which is connected with the second end of the first connecting arm, and a second connecting arm, a first end of which is connected with a second end of the contact arm, and a second end of which is substantially extended downwards to the base plate so as to be contactable with the base plate. The connector has multiple connecting paths, thus realizing good high-frequency characteristics. | 05-31-2012 |
20150153105 | BAKING DEVICE FOR LIQUID CRYSTAL ALIGNMENT FILMS - The present disclosure provides a baking device for liquid crystal alignment films, wherein the baking device includes a heating table with openings and lift pins extending and penetrating through the openings, and the lift pins can move between a retracting position and a stretching position to support a glass substrate coated with alignment films, wherein a blocking member is arranged on the lift pin in a surrounding manner to be tightly engaged thereon, so as to block the air stream flowing toward the glass substrate through the openings when the lift pins are situated in the retracting position. With the provision of the blocking members, the air streams flowing toward the glass substrate coated with alignment films can be resisted in the baking process, which prevents the air streams from affecting heat distribution and temperature distribution. | 06-04-2015 |
20150184794 | Quartz Clip Device And Manufacturing Method Thereof And OLED High-Temperature Oven Having Same - The present invention provides a quartz clip device and a manufacturing method thereof and an OLED high-temperature oven having the quartz clip device. The quartz clip device includes: a base ( | 07-02-2015 |
20150202849 | INSTALLING STRUCTURE FOR PLATE FIXING MEMBER FOR LAMINATING MACHINE, TOP PLATE AND LAMINATING MACHINE - The present disclosure relates to a device for mounting a plate fixing member in a laminating machine, including a mounting slot for mounting the plate fixing member. The plate fixing member is arranged in the mounting slot and can move vertically in the mounting slot. An elastic reset member is arranged between the plate fixing member and the mounting slot. With the movable plate fixing member being arranged in the mounting slot and the movement of the plate fixing member in the mounting slot being controlled by the elastic reset member, the plate fixing member can move into the mounting slot without an overpressure phenomenon of the glass plates at the plate fixing member when the top plate moves downwards and press-fits the upper glass plate and the lower glass plate. Therefore, the yield of products can be improved, and the production cost can be reduced. The present disclosure further relates to a top plate for a laminating machine and a laminating machine, with which the overpressure phenomenon of the glass plates caused by the plate fixing member can be effectively reduced. | 07-23-2015 |
