  • APPARATUS AND METHOD FOR ANALYZING CELLS BY USING STATE INFORMATION OF CHROMOSOME STRUCTURE
    Publication number: 20260171191
    Abstract: Disclosed are an apparatus and method for analyzing cells by using state information of a chromosome structure. The present invention determines whether diseased cells are present in a cell group collected from a sample of a subject through state analysis of a chromosome structure, and predicts the tissue origin and quantity of the diseased cells. According to the present invention, it is possible to classify diseased cells with high accuracy at a low price, and to perform quantitative measurement more easily and accurately than conventional cell staining methods.

  • Indirect lighting apparatus
    Patent number: 9423084
    Abstract: An indirect lighting apparatus includes a light-emitting device, a reflector disposed above the light-emitting device, and a wavelength conversion layer disposed on a surface of the reflector facing the light-emitting device and spaced apart from the light-emitting device. The wavelength conversion layer includes phosphors configured to change the wavelength of light emitted from the light-emitting device. The reflector is configured to reflect light emitted from the wavelength conversion layer, back towards the wavelength conversion layer.
