摘要： Characteristic amounts in each small region of audio signals transmitted in the working system and the standby system are extracted by characteristic amount calculators 6-1, 6-2. A characteristic amount comparator 7 compares the characteristic amounts and judges occurrence of a fault. Characteristic amount difference calculators 9-1, 9-2, ∥D∥ comparator 10, and faulty system judging unit 11 judges the system having a fault. Majority decision processor 12 and significance judging unit 13 enhance the reliability of the judgment. Delay difference of audio signals between systems is roughly detected by sub-sampling audio signals of two systems and comparing them, and then accurately detected without sub-sampling. Delay difference between audio signals is adjusted by the detected delay difference.

摘要： The present invention provides a method of generating a virtual viewpoint video image when the virtual viewpoint position is not located on a plane where a camera is disposed. In an environment in which a plurality of cameras having a horizontal optical axis are disposed in a real zone (for example, on the circumference) which surrounds an object, a video image of an arbitrary viewpoint on the circumference is generated. Further, by synthesizing video images photographed by a camera, a free viewpoint video image is generated from a virtual viewpoint (viewpoint from a high or low position) where no camera is placed. According to a method of achieving this, a travel distance of a display position is calculated by the local region synthesizing portion and this travel distance is reflected to the free viewpoint video image of a local region.

摘要： A headrest for vehicle seat includes: a generally inverted-U-shaped frame having a pair of headrest stays defined therein; and an impact absorption bar fixedly connected between those two headrest stays. The impact absorption bar is located in a predetermined spaced relation with an upper horizontal frame portion of the generally inverted-U-shaped frame. When a rear-end collision or the like occurs, a head of seat occupant is stably received by those impact absorption bar and upper horizontal frame portion, while the impact absorption bar being readily deformed by backward excessive great load applied thereto from the seat occupant's head to thereby absorb and reduce a corresponding impact energy to be imparted to the head.

摘要： A crank element is arranged rotatably between two support elements so as to prevent removal therefrom. The crank element is formed with a pair of generally inverted-L-shaped end portions each having a horizontal first end region and a vertical second end region bent from that first end region. Each of those two end portions is rotatably secured via retainer bush in each of two through-holes formed in the respective two support elements. The two through-holes each has an elongated hole region and a circular hole region. The retainer bush is resiliently deformable and has: a through-bore in which the first end region of crank element is rotatably support; and a groove portion in which the circular hole region of the through-hole is closely engaged.

摘要： In a non-critical pressure region where a pressure ratio [Pm/Pthrup(i−1)] of an intake air pressure Pm(throttle downstream pressure) detected by an intake air pressure sensor to a previous throttle upstream pressure Pthrup(i−1) is greater than a predetermined value B, the previous throttle upstream pressure Pthrup(i−1) is substituted for one of two terms of the throttle upstream pressures Pthrup(i) included in an intake system model so that present throttle upstream pressure Pthrup(i) is calculated. In a critical pressure region where the pressure ratio is less than or equal to the predetermined value B, a physical value f(Pm/Pthrup(i)) using a pressure ratio [Pm/Pthrup(i)] of the intake air pressure Pm to a present throttle upstream pressure Pthrup(i) as a parameter is regarded as a steady value fc so that the present throttle upstream pressure Pthrup(i) is calculated.
