  • Patent number: 10655704
    Abstract: The geometrically nonlinear isolation system of the present invention includes a bearing platform, an isolator and a damper. The isolator is connected with the bearing platform and used for providing resilience against horizontal relative displacement between the bearing platform and the isolator. The damper is pin-jointed to the bearing platform and has an axis orthogonal or oblique to the horizontal direction. Accordingly, when the bearing platform and the isolator move with respect to each other along the horizontal direction, the angle between the axis of the damper and the horizontal direction would change with the horizontal displacement, and the damper provides damping force along a direction parallel to the axis of the damper so as to enhance horizontal vibration isolation effect.

  • Patent number: 10352698
    Abstract: Disclosed is a composite hydrological monitoring system, in which a counterweight component and a test component are respectively connected to both opposite ends of a strip and a plurality of sensors are disposed at different vertical positions. Accordingly, the scour depth can be measured by sensing the location of the counterweight component, whereas the water level and/or flow velocity can be determined by signals from the sensors. When the counterweight component moves downward with sinking of the riverbed, the strip would be pulled down and thus causes the test component to present a change in mechanical energy. Accordingly, the sinking depth can be measured by sensing the change of the mechanical energy. Additionally, since the water level variation would cause signal changes of the sensors arranged in a row along a vertical direction, the change of water level can be determined accordingly.
