  • Publication number: 20250123200
    Abstract: A method for detecting an object containing recycled plastic materials by qualitative and semi-quantitative detections is revealed, in which observing a yellowing condition of the object using a first light source, and illuminating the object using a second light source for observing a defect amount on the surface image of the object. When a yellowing index of the object is smaller than a standard yellowing index as well as a second defect condition is greater than a first defect condition, and an activation energy value of the object from a thermogravimetric analyzer is smaller than a standard activation energy value, the object does contain recycled plastic materials. Since the spectrums of recycled PET and native PET are different, the object contains recycled PET and the proportion of the recycled PET are determined according to the spectrums of fluorescent spectrum analysis and the difference ratio between the spectrums respectively.

  • Publication number: 20250120623
    Abstract: A blood characteristic measurer includes multiple light sources, a light sensor and a processor. The multiple light sources emit multiple beams of light of different dominant lightening wavelength. The light sensor receives multiple reflected light beams due to the reflection of incident light from a skin surface. The processor is electrically coupled to the light sensor and produces the blood characteristic according to reconstructed spectra generated by the multiple reflected light beams and absorption coefficient spectra generated by the skin surface.
