Abstract: In a tire design method, a numerical optimization is performed according to a basis vector process using an FEM model to obtain an optimal solution which optimizes an objective function for a tread pattern shape. A numerical optimization is performed according to an ECAT using the FEM model to obtain an optimal solution which optimizes the objective function for the tread pattern shape. Either of the calculations is executed first, and the optimal solution obtained at the first calculation is used as an initial shape when the other numerical optimization is performed.

Abstract: An initial layout of one pitch unit of a tire tread pattern is decided. A finite element model of a tire is created by developing the one pitch unit of the initial layout into a plurality of pitches in the circumferential direction of the tire to carry out a structural analysis.

Elements to be added are selected from among the elements which have been removed to decide a layout of the current generation. A finite element model of a tire is created by developing the layout of the current generation into a plurality of pitches to carry out a structural analysis, and convergence of an objective function is determined.

Abstract: An AGC control section (110) has a first operation mode for controlling the gain of a variable gain amplifier (103) to maintain the amplitude of the sync signal measured by a sync signal amplitude measuring circuit (108) at a constant value, and a second operation mode for preventing the gain from being increased even when the amplitude of the sync signal measured by the video signal processing circuit (109) is smaller than the predetermined first reference value and reducing the gain of the variable gain amplifier (103) only when the amplitude of the video signal exceeds a predetermined second reference value. During operation in the first operation mode, when the amplitude of the sync signal is smaller than the predetermined first reference value and the amplitude of the video signal is greater than the predetermined second reference value, the mode is switched to the second operation mode.

Abstract: A Y/C separator improving characteristics of dot crawl elimination and cross-color interference elimination even at a sampling frequency unequal to an integer multiple of a color subcarrier frequency of an NTSC television signal. A received composite color television signal is quantized by a clock signal with a frequency synchronized to the horizontal sync signal of an input signal. Chrominance component values are extracted in various directions of a target sample by using neighboring samples of the target sample. The chrominance component is obtained by selecting and outputting the extracted chrominance component values in accordance with correlation values of the corresponding samples from which the color component is removed. The calculation of the chrominance component extraction value is carried out by detecting the phase rotation angle of the color subcarrier signal per clock near the target sample, and in response to the detected value.

Abstract: A region-of-interest (ROI) setting apparatus for respiration monitoring and a respiration monitoring system capable of setting an ROI in an automatic manner. Absolute values of subtractions between every successive two of a plurality of frame images photographed by a CCD camera 2 for a period of time equal to half a respiration period are calculated, then summed and stored. Based on the change information thus calculated and stored, the position and size of each changed region is calculated. Provisional regions are set from the changed regions successively from the greatest to the smallest one thereof. In each of these provisional regions, it is determined whether a gray level histogram indicative of distribution of the number of pixels for respective gray level values includes a twin peak characteristic having twin peaks each equal to or higher than a predetermined value, and whether the area of the corresponding changed region is equal to or greater than a predetermined value.
