  • Patent number: 11395605
    Abstract: An impact control system includes a supporting structure with gravity compensation mechanism, and a supporting bed which is supported by the supporting structure and supports an impact target. Here, the supporting structure includes an elastic element, a vertical support to which one end of the elastic element is fixed, a horizontal support to which the other end of the elastic element is fixed, and which is rotatable around a rotation axis disposed at one end of the horizontal support meeting an end of the vertical support, and a weight support part which is connected to the other end of the horizontal support and supports the supporting bed while contacting a lower surface of the supporting bed.
    Type: Grant

  • Patent number: 11054323
    Abstract: A quantitative impact control and measurement system includes an impactor configured to apply an impact to a target, a control device configured to control movement of the impactor, an acceleration sensor mounted to a base of the impactor, and an impact sensor mounted to a terminal of the impactor. Here, the control device calculates an impact actually applied to the target from signals measured through the acceleration sensor and the impact sensor.
