  • Patent number: 10092210
    Abstract: The present invention relates to an impedance measuring device obtaining impedance of portions of an object corresponding to two sensing electrodes by detecting, through the two sensing electrodes, an electrical variation shown on the object as an electrical signal is applied. A detector amplifying each of signals detected through the two sensing electrodes and then differential-operating the amplified signals to generate a signal for obtaining impedance is subjected to a calibration process for adjusting the gain of the amplifiers to reduce in-phase noise added due to an imbalance between the sensing electrodes.

  • Patent number: 9546926
    Abstract: A method for inspecting a light source module for defects includes preparing a board on which a light emitting device and a lens covering the light emitting device are installed. A current is applied to the light emitting device to turn on the light emitting device. The lens is imaged with the light emitting device turned on. A central symmetry denoting a symmetry of light emission distribution from the center of the lens is calculated based on the obtained image, and the calculated central symmetry is compared with a reference value to determine whether unsymmetrical light emission distribution has occurred. Various other methods and apparatuses for inspecting light source modules are additionally provided.
