  • Patent number: 9838612
    Abstract: An inspecting device for inspecting an inspection target is provided. The inspecting device includes a mono-color image-retrieving module, illuminating modules and a control module. The mono-color image-retrieving module is disposed above the inspection target with an optical axis orienting toward the inspection target. Each of the illuminating modules includes light-emitting elements of different colors. The control module controls the illuminating modules to sequentially generate illuminating lights both in an order of different colors and different incident angles to further control the mono-color image-retrieving module to sequentially retrieve mono-color images each in response to one illumination of the illuminating lights. The control module performs an inspection of the inspection target based on the mono-color images.

  • Patent number: 4893506
    Abstract: An apparatus and method for estimating rainfall. A rainfall sensing device is used to generate rain signal Vo; when it is raining (Vo=1), a number of consecutive sampled rain signals are picked up within a given period of time. The conditions (shower, heavy rain, light rain or no rain) of rainfall are estimated by comparing the sampled rain signals to predetermined raining index N1 and no-rain index N2. The rainfall sensing device comprises a Wheatstone bridge circuit and a differential amplifier. The two adjacent branches of the Wheatstone bridge circuit are provided with a thermal resistor as a rain-sensor and a thermal resistor as a temperature compensating element respectively.
