  • Publication number: 20220218287
    Abstract: Provided are a disease-condition assessment device for assessing a disease condition of a subject, a disease-condition assessment method, a program for disease-condition assessment device, and a disease-condition assessment system. The disease condition assessment device acquires a data of a seat pressure distribution on a seating surface where a subject operating a vehicle is seated, calculates a center position depending on the seat pressure distribution, calculates a degree of laterality in the seat pressure distribution based on the center position, and assesses a disease condition of the subject depending on the degree of laterality.

  • Patent number: 7509872
    Abstract: Provided are a stress analysis method and stress analysis equipment that enable a detailed stress measurement, by using both a photoelasticity measurement method and a stress measurement (mechanoluminescence measurement) which utilizes a mechanoluminescent substance to measure a stress state of an object. Physical quantities that are measurable include individual principal stress component and a principal stress direction. The photoelasticity measurement method alone cannot measure individual principal stress component values.

  • Publication number: 20020158639
    Abstract: There are provided a laminate with an inside layer circuit for use as a multilayer printed circuit board, a method for measuring a circuit impedance of the laminate, and a measuring device that enables a nondestructive impedance measurement accurately. The laminate with the inside layer circuit has a dielectric substrate, a first conductive layer disposed on an upper surface of the dielectric substrate to form a high frequency circuit, a second conductive layer disposed on a lower surface of the dielectric substrate, and a third conductive layer disposed over a first dielectric layer on the upper surface of the dielectric substrate. A test conductor is formed independently of the inside layer circuit within the first conductive layer.
