摘要： Medical image data is utilized, physical values are assigned to body parts based on image information, and the target organs are separated from the image data to prepare a 3D biodata model to thereby realize a data model unique to a patient, having an internal structure, and enabling dynamic simulation of a live body. The same target part of a body is captured by CT and MRI to obtain medical images. Sets of pairs of CT images and MRI images are set, a plurality of features showing the same locations are selected and set from the sets of CT images and MRI images, a conversion coefficient between the CT images and MRI images is obtained, and this conversion coefficient is used to rearrange the MRI images by projection transforms and linear interpolation, combine them with the contours of the CT images, and correct their positions in the contours. Further, the images are used to prepare a 3D data model.

摘要： The invention provides a simulation system and method having an image generating function that can visualize the behavior of an object of analysis in real time. The behavior of the object of analysis is divided into a plurality of subspaces, and is visualized as subspace images by an MP method by performing simulation computations for the respective subspaces at nodes 431 to 438. The subspace images are sent to a pipelined composer 44 where the images are blended together by considering occlusion relationships determined by reference to a viewpoint by a BSP method. The resulting composited image is corrected for distortion at a server 40 by using a texture mapping function, and is displayed on a display apparatus 41.

摘要： A free weight unit with a spinning mass element, which comprises a casing for accommodating the spinning mass element in a rotatable manner about a rotation axis, and also accommodating an electric motor for rotationally driving the mass element and a battery for the electric motor. This free weight unit is designed to be used effectively for training, rehabilitating or physical exercising of the human body, and the-casing generally has a relatively large dimension sufficient to accommodate a relatively large mass element, which may be difficult to be gripped directly by hand. In this free weight unit, a certain vector of the precessional output torque is generated due to an input torque applied to the spinning mass element rotating about the rotation axis, by operating a selected one of the two elongated sections of the shiftable member to turn about a certain input axis extending in a direction different from a direction of the rotation axis.

摘要： An optical gyro includes: an optical propagation path in cooperation with a rotation axis, for propagating a pair of light beams therethrough simultaneously clockwise and counterclockwise, respectively, and causing a phase difference of light based on Sagnac effect; an optical system optically coupled to the optical propagation path, for effecting a generation, a distribution or coupling, a polarization, a frequency shift and a phase modulation of light beams and transducing a light beam indicating the phase difference of light into a corresponding electric signal to output a photoelectric output signal; and a signal processing circuit operatively connected to the optical system. The signal processing circuit effects a digital demodulation for the photoelectric output signal to obtain a signal proportional to an angular velocity with respect to the rotation axis, thereby realizing a stable phase modulation and an improvement in characteristics of the optical gyro. Also, it is possible to expand a maximum range of detection of the input angular velocity.
