  • Patent number: 11369307
    Abstract: A vestibular system examination device includes a platform unit and an examination unit. The platform unit includes a base, a driving mechanism mounted to the base, and a seat mounted to the driving mechanism and adapted for a user to sit thereon. The seat is driven movably and rotatably with six degrees of freedom by the driving mechanism. The examining unit includes a detector adapted for detecting eye movement or electrooculography of the user, a measuring module electrically connected to the platform unit for measuring location and displacement thereof, and a processing module electrically connected to the detector and the measuring module for receiving and processing data acquired from the detector and the measuring module.

  • Patent number: 10506967
    Abstract: A multi-axis measurement device for loading force and center of gravity is provided comprising a first loading plate, and comprising: a first slidable element and a first piezoelectric pressure sensing element. A second loading plate comprising: a second slidable element and a second piezoelectric pressure sensing element. A connecting plate, respectively connects to the first slidable element, the first piezoelectric pressure sensing element, the second slidable element, and the second piezoelectric pressure sensing element. A plurality of third piezoelectric pressure sensing elements connects to the first loading plate. The first piezoelectric pressure sensing element measures the changes in force of the X-axis direction, the second piezoelectric pressure sensor element sensing element measures the changes in force of the Y-axis direction, and the third piezoelectric pressure sensor element sensing elements measure the changes in force of the Z-axis direction.
