Abstract: The present invention is a lighting control system including at least one local device and a plurality of lighting devices. The communication transmission medium between the local device and the lighting devices is provided with directional characteristics, and the lighting devices are selected and designated, as needed, using ID information. A designated lighting device is lighted up and performs light intensity setting. A judgment is carried out as to whether or not the relation between an illumination at a desired position and a target illumination satisfies a predetermined condition, and causes the illumination at the desired position to approach the target illumination by letting the plurality of lighting devices successively perform a procedure of increasing/decreasing their respective light intensities based on a result of the judgment.

Abstract: A method of measuring of the present invention includes the steps of photographing a rotating body with the curved surface having marks to obtain two-dimensional images thereof; generating a three-dimensional imaginary body with the curved surface having marks; setting an arbitrary posture of the imaginary body as a reference posture, performing a posture displacement operation in such a way that the marks of the imaginary body are coincident with the marks of the body; specifying a three-dimensional posture of the body on the basis of an amount of the posture displacement operation relative to the reference posture; and determining the rotational amount of the body and the direction of the rotational axis thereof by computing a rotation matrix relating to a rotation operation to make the three-dimensional posture of the body at one time coincident with that at another time.

Abstract: The invention judges whether or not the relation between an illumination at a desired position and a target illumination satisfies a predetermined condition, and causes the illumination at the desired position to approach the target illumination by letting a plurality of lighting devices successively perform a procedure of increasing/decreasing their respective light intensities based on a result of the judgment. The illumination at the desired position is caused to approach the target illumination by randomly varying the light intensities of the lighting devices, making comparison between the illumination at the desired position and the target illumination, and narrowing the width of variation based on a result of the comparison. When the electric power consumption has increased, the light intensities are returned to the previous values. Furthermore, there is provided a control terminal device for control that can be used for other control amounts.

Abstract: A reference posture and a reference position of the imaginary sphere and an arbitrary position are set. The relationship between three-dimensional coordinates and two-dimensional coordinates is derived by using a photographing means. Positions of marks given to the imaginary sphere formed at the coordinates in the three-dimensional space are converted into positions on a two-dimensional image. An operation of displacing a posture of the imaginary sphere relative to the reference posture and the reference position is performed in such a way that the coordinate values of the two-dimensional imaginary marks and the coordinate values of the marks present on the two-dimensional images of the sphere are coincident with each other. The rotational and flight characteristics of the sphere are computed, according to the three-dimensional posture and position at one time and the three-dimensional posture and position thereof at another time.

Abstract: A sphere having a plurality of marks given to the surface thereof is photographed at a plurality of times to obtain a plurality of two-dimensional images of said sphere. An imaginary sphere having a plurality of marks given to the surface thereof is generated in a three-dimensional coordinate space by a computer. In making the imaginary sphere placed in a reference posture coincident with the posture of the two-dimensional image, an optimum displacement amount of said posture of said imaginary sphere is determined by using a computation based on Genetic Algorithms. A rotation matrix is derived from the posture of the sphere measured for each dimensional image thereof and a computation is performed on the rotation matrix to thereby obtain the rotational amount of the sphere and the direction of its rotational axis.

Abstract: A reference posture and a reference position of the imaginary Sphere and an arbitrary position are set. The relationship between three-dimensional coordinates and two-dimensional coordinates is derived by using a photographing means. Positions of marks given to the imaginary sphere formed at the coordinates in the three-dimensional space are converted into positions on a two-dimensional image. An operation of displacing a posture of the imaginary sphere relative to the reference posture and the reference position is performed in such a way that the coordinate values of the two-dimensional imaginary marks and the coordinate values of the marks present on the two-dimensional images of the sphere are coincident with each other. The rotational and flight characteristics of the sphere are computed, according to the three-dimensional posture and position at one time and the three-dimensional posture and position thereof at another time.

Abstract: The present invention provides a pipe-shaped structural member made of fiber reinforced plastics or fiber reinforced rubber utilizing the mechanical property of the material as an anisotropic material. Since the angle of the fibers and/or direction of orientation are made partially different in the circumferential direction of the structural member, and moreover, since the part where the angle of fibers and/or direction of orientation are made partially different is at least a part in the thicknesswise direction of the circumferential part, the pipe-shaped structural member shows a peculiar style of deformation, and is applicable to a variety of industrial fields.
