  • Patent number: 9140619
    Abstract: A piezoelectric vacuum gauge includes an actuator with a flexible portion, an actuating unit, a sensor unit, a signal input terminal and a signal output terminal, and a fixture unit having a base portion and a cover portion. An external signal is generated by a signal generator. Receive and transmit an external signal to an actuating unit by the signal input terminal so that the actuating unit has a vibration. Prompt a flexible portion by the actuating unit to produce a first resonant motion when the actuating unit having the vibration. The first resonant motion converts into a second resonant motion because the flexible portion is subject to a damping force of ambient air. Prompt a sensor unit by the second resonant motion to cause a shape transformation of the sensor unit to generate a detecting signal. Output the detecting signal to an external instrument by a signal output terminal of sensor unit to calculate a vacuum pressure value.

  • Patent number: 9116854
    Abstract: An image correlation for images having speckle pattern is evaluated. Modulation transfer function (MTF) curves of speckle-pattern images captured at different times are figured out. Whether a correlation value between the MTF curves meets a threshold is checked. If the correlation value is smaller than the threshold, speckle-pattern images are re-selected for re-figuring out the MTF curves and the correlation value. Thus, error of strain and displacement for digital image correlation owing to blurring images of the on-moving target object is figured out; calculation time of the digital image correlation is reduced; and accuracy on measuring physical parameters of the target object before and after movement is improved for digital image correlation.

  • Patent number: 9077143
    Abstract: An optical fiber apparatus is suitable to operate under irradiation, more particularly to mitigating the damage of a rare-earth-doped optical fiber element as part of an optical fiber assembly causes by irradiation. The irradiation mitigation attributes to a photo-annealing apparatus including at least a shorter wavelength photo-annealing spectral content, which is relative to that of a pump light source, for effectively photo-annealing the rare-earth-doped fiber element. Photo-annealing by such shorter wavelength light results in a fast and nearly complete recovery of radiation induced attenuation of the rare-earth-doped optical fiber element in the wavelength range from 900 nm to 1700 nm.
