  • Publication number: 20100227291
    Abstract: Described are a method and device for determining three-dimensional position information of a surface of a translucent object having a wavelength-dependent transmittance and reflectance characteristics. The method includes illuminating the surface of the translucent object with optical radiation at a predetermined wavelength emitted from a pair of optical sources. Radiation scattered from the surface and below the surface is detected, and a phase of the optical radiation from one of the optical sources relative to a phase of the optical radiation from the other optical source is changed before again detecting the scattered radiation. The predetermined wavelength is selected so that the optical radiation scattered from below the surface and detected provides a substantially constant background intensity with respect to the optical radiation scattered from the surface and detected. Three-dimensional position information of the surface is calculated in response to the detected radiation.

  • Publication number: 20100077924
    Abstract: The present invention relates to air purification techniques and provides an air purifier. The air purifier comprises a shell with an air inlet and an air outlet. An electric field filter, an air passage and a blower are disposed inside the shell. The electric field filter comprises a filter frame disposed at the air outlet and a grid base disposed under the filter frame. A filter is provided inside the filter frame. One end of the air passage connects with the grid base and the other end connects with the blower. The blower is disposed at the air inlet. The filter frame and the grid base are integrated as a hermetic whole. Due to the integrated configuration of the filter frame and the grid base, when removing out the electric field filter, the power is cut automatically. This effectively prevents an occurrence of the electroshock, and improves safety performance of the purifier. Furthermore, air leakage can be greatly reduced, for there is no gap between the filter frame and the grid base.

  • Publication number: 20050117162
    Abstract: A non-contact gauge and method of use is provided for optical measurement of an object or objects. The apparatus and methods may comprise a laser providing a projected laser beam; a work-piece holder for holding the object to be measured; a light sensitive sensor located to sense the beam as the beam is diffracted by at least one edge of the object and as the beam forms a near field Fresnel diffraction fringe pattern upon elements of the sensor. The laser and the sensor are located to enable near-field Fresnel diffraction. A fringe pattern signal analyzer may be included for computing mathematical algorithms to determine the position (X0) of at least one edge of the object based upon the diffraction pattern sensed by the sensor wherein the fringe pattern signal analyzer is structured to refine sensed fringe pattern edge position data to be more accurate based upon a theoretical diffraction compensation factor.
