    Abstract: The bioinstrumentation apparatus includes a light irradiation unit irradiating a measurement region with light, a light detection unit detecting diffused light from the measurement region, and a computing unit generating a reconstructed image for the interior of the measurement region. The computing unit calculates J coefficients wj set for every pixel of the reconstructed image and more than 0 and not more than 1 (where J is the number of pixels of the reconstructed image) and carries out successive approximation computation by the following iterative formula xj(k+1)=xj(k)+wjdj(k) (where k is an integer from 1 to N, N is the number of times of iterative computation, xj(k) is a pixel value of the jth pixel on the kth iterative computation, and dj(k) is an update amount of the jth pixel on the kth iterative computation) to generate the reconstructed image.

  • Patent number: 7625516
    Abstract: A manufacturing method for a sheet molded body having a desired three dimensional shape and an excellent quality of the design, which has no crease, by uniformly expanding a decorated sheet prior to molding, and closely contacting the decorate sheet to the surface of a male die. In the manufacturing method, the pressure at the front side of the decorated sheet is lowered relative to that at the back side. An arm means is then moved towards the decorated sheet from the back side of the decorated sheet so that the decorated sheet is inverted by increasing the pressure at the front side relative to that at the back side. The decorated sheet is then three dimensionally formed along the surface of the male die by, while pressing the male die from the back side and moving the arm means backwards, increasing the pressure at the front side.

  • Patent number: 6687521
    Abstract: The present device is equipped with a measurement site holder 3 that is constructed using a negative impression of the measurement site 10. As a result, variation in the measured values caused by the non-uniform distribution of components in the measurement site 10 is reduced, so that variation in the measured values caused by variations in the light path length accompanying variations in the shape of the measurement site 10, and by variations in blood flow or the like that accompany differences in the contact pressure, can be reduced. Since living-body information and measurement parameters for the patient are recorded on a recording medium 11 mounted on a measurement site holder 3 for the exclusive use of the individual patient, the erroneous acquisition of living-body information for individual patients can be prevented, and reproducible measurements can be performed.
