  • Publication number: 20160209547
    Abstract: Disclosed therein are an inspection apparatus for a thermo-hygrometer based on phase change and methods for controlling and inspecting the same which can simultaneously inspect a thermometer and a hygrometer through a simple method using a phase change of reactants. The thermo-hygrometer based on phase change includes: reactants of at least two kinds; a plurality of cylinder type cells; a reactor body having a temperature sensor hole and a plurality of cell holes; a flow pipe in which a first gas circulates by a circulation pump; a relative humidity chamber which has a relative humidity sensor disposed therein; and a temperature control unit which is mounted below the reactor body, wherein when a phase change of a first reactant is induced, the relative humidity sensor is inspected based on the relative humidity of the first gas, and the temperature sensor is inspected based on the phase change temperature of the first reactant.

  • Patent number: 9395244
    Abstract: Miniature spectrometers produce low resolution spectral data due to their size limitations. A method for processing these spectral data is proposed. The spectral data from a low resolution spectrometer is enhanced to a higher resolution, or processed to be in the wavelength domain. This process is called spectrum reconstruction, and can be used in low cost and miniature spectrometers with limited spectral resolution. The proposed method is noise robust, adapts to input spectrum, and can be used across many types of spectrometric devices without any manual adjustment of parameters.
