  • Patent number: 12114007
    Abstract: For the purpose of providing an image encoding technique for reducing the amount of codes, in inter prediction in which motion search is performed by using a block obtained by dividing an input image and a reference image, the motion vector of the block is predicted by selecting from the motion vectors of the surrounding blocks. Further, in the method of calculating a differential vector and then performing encoding, the number or positions of candidate blocks from which a prediction vector is selected are changed block by block or frame by frame and thereby adaptive and efficient video image compression is performed.

  • Publication number: 20220326179
    Abstract: The present invention aims to provide a biological sample analysis device which achieves an improvement in accuracy of an analysis result, a reduction in reagent cost, and shortening of a required time. The biological sample analysis device according to the present invention compares first measurement data acquired by measuring a biological sample and second measurement data acquired by measuring a reference sample and determines that when the difference between the two exceeds a threshold value, it is necessary to remeasure the reference sample before remeasuring the biological sample and reacquire a reference value (refer to FIG. 3A).

  • Publication number: 20220189577
    Abstract: A genotype analysis device includes an electrophoresis device and a data analysis device. A mobility model management unit including an environment information receiving unit, a prediction model storage unit, and a mobility prediction unit is provided in an STR analysis unit of the data analysis device. The mobility prediction unit generates a prediction model for predicting a correction amount of a standard base length of an allele, based upon an environmental condition at the time of electrophoresis received by the environmental information receiving unit and an electrophoresis result of an allelic ladder. A base length of the allele is corrected from the environmental condition without using the allelic ladder by using the prediction model.

  • Patent number: 10682825
    Abstract: A method of manufacturing a pneumatic tire includes forming a green tire. Forming the green tire includes: a first step of forming a first belt portion by winding a first belt on an outer peripheral surface of an inner liner and, thereafter, forming a second belt portion by winding a second belt on the first belt portion thus acquiring a belt layer; and a second step of acquiring a reinforcing layer by winding a reinforcing belt on the second belt portion. The second step includes: a first parallel winding treatment where the reinforcing belt is wound one turn on a first circumference; a spiral winding treatment where the reinforcing belt is spirally wound in a tire width direction; and a second parallel winding treatment where the reinforcing belt is wound on a second circumference within a range of from 240°±30° with one turn set to 360°.
