  • Patent number: 11506489
    Abstract: A contour accuracy measuring system and a contour accuracy measuring method are provided. The contour accuracy measuring system captures location coordinate data of shafts of a machine tool. The location coordinate data are calculated to obtain a first true round trajectory on an inclined plane as reference information. The contour accuracy measuring system then adjusts parameters of the locations of the shafts based on the location coordinate data of the shafts of the reference information to generate a second true round trajectory on the inclined plane, so as to get to know whether the locations of the shafts after the parameters are adjusted comply with a standard. Therefore, the overall measurement process can be speeded up by automatically measuring the parameters and automatically testing an operating status.

  • Patent number: 9541954
    Abstract: A portable electronic device includes first and second bodies. The first body includes a guiding rail, a restoring component, a first magnet disposed in the guiding rail, top and bottom surfaces. The guiding rail is connected between the top and bottom surfaces. The restoring component is disposed at one end of the guiding rail close to the top surface. The second body including a second magnet is pivotally connected to the first body for rotating from leaning on the top surface till leaning on the bottom surface. When the second body leans on the top surface, the first magnet is attracted to the second magnet to lean on the restoring component. When the second body leans on the bottom surface, an attraction force between the first and second magnets is greater than a restoring force provided by the restoring component so the second magnet moves toward the bottom surface.
