Abstract: An endoscopy system including a flexible insertion tube, a motion sensing device and a processor is provided. The flexible insertion tube has a central axis. The motion sensing device includes a housing, a plurality of patterns and a plurality of sensors. The patterns are disposed at a surface of the flexible insertion tube according to an axial orientation distribution and an angle distribution based on the central axis. During the relative motion of the flexible insertion tube between the motion sensing device via a guiding hole, the sensors sense a motion state of the patterns so as to obtain a motion-state sensing result. The processor determines an insertion depth information and an insertion tube rotating angle information based on the motion-state sensing result, the axial orientation distribution and the angle distribution. A method of reconstructing a three-dimensional structure is also provided.

Abstract: An electric device with data detection function and a data detection method thereof. The device comprises an analysis module, an input module, a recognition module, a comparison module and a display module. The analysis module receives sensor information and analyzes the sensor information to get analysis information. The input module allows users to input feedback information. The recognition module is electrically connected to the input module; the recognition module recognizes and converts the feedback information into digital information. The comparison module is electrically connected to the input module and the recognition module. The comparison module compares the analysis information and the feedback information or the digital information to get a comparison result. The display module displays the analysis information or the comparison result.

Abstract: A waterproof camera including an image capturing module, a shell and a plurality of control buttons. The image capturing module is provided for capturing an image, and further includes a lens, which is a prism type lens installed in the camera. The shell is provided for sealing and covering the whole camera, and includes a window component made of a transparent material and installed correspondingly to a position of image capturing module. The control buttons are arranged on the shell for controlling an operation of the camera and the control buttons are sealed with the shell to achieve the waterproof effect of the camera.
