Latest Patents

Guanhua Xu holds a patent for a "Precision tilting platform device used for static calibration of seismometers." This device includes a base, a worktable, a rotary part, a driving part, a measuring part, and supporting frames. The rotary part consists of a shaft, a driving arm, a rotary table, and a clump weight. The driving part features a linear motor, a sliding table, a pair of linear guides and sliders, and a grating scale. The readhead of the grating scale is fixed with the base and sends out a signal of zero position when the worktable is horizontal. The sliding table contacts the driving arm, allowing for precise movements. When the linear motor moves forward, the rotary part rotates toward the positive direction, and when it moves backward, the rotary part rotates toward the negative direction under the gravity of the clump weight. The measuring part includes a laser interferometer and a reflector to obtain the tilting angle of the worktable. This innovative device enhances the calibration process for seismometers, ensuring more accurate readings.
