  • Patent number: 8497260
    Abstract: 2-arylbenzothiophene derivatives or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition for the diagnosis or treatment of degenerative brain disease containing the same as an active ingredient. Since the 2-arylbenzothiophene derivatives of Formula 1 have a relatively high binding affinity for ?-amyloid, they can be used as diagnostic reagents for diagnosing Alzheimer's disease at an early stage by non-invasive techniques when they are labeled with radioisotopes: wherein R1-R4, V, W, X, Y and Z are as defined in the Detailed Descript of the specification. Further, when the pharmaceutical composition containing the 2-arylbenzothiophene derivative binds with a low-molecular weight ?-amyloid peptide binding compound, generation of malignant high-molecular weight ?-amyloid deposits is minimized. Accordingly, the pharmaceutical composition can be used as a therapeutic agent of degenerative brain disease such as Alzheimer's disease.

  • Patent number: 8422604
    Abstract: Provided is a method for detecting frame sync and frame structure in a satellite broadcasting system, which acquires an estimated value for detecting frame structure and frame sync and overcomes distortion of correlation analysis values by summing differential correlation values for SOF positions in consideration of the variable frame length, and selecting a maximum value in a channel environment with low signal-to-noise ratio and high frequency error. SOF is a sync word indicating the start point of a frame. The method includes the steps of: acquiring SOF differential correlation value sequences; acquiring sums (di,t) of the correlation values normalized for SOF positions based on the number of symbols per frame by using the above-generated SOF differential correlation value sequences; and selecting a maximum value (dz,x) among the sums of correlation values, detecting z as a frame sync position, and detecting x as a frame structure index.

  • Patent number: 8405835
    Abstract: The present invention relates to a scanning microscope using a heterodyne interferometer, which can be used for mapping or imaging complex optical parameters such as physical structures and material properties of a sample under test. The heterodyne interferometer is designed to provide in- and quadrature-phase interference signal which can be used for extracting the phase and amplitude change induced on the probe beam. The phase and the amplitude of the probe beam, which is reflected from or transmitted through the sample, are modified by the physical structures and material properties of the sample. Therefore, by scanning the probe beam, local variations of the phase and amplitude can be mapped, and, thereby, three-dimensional microscopic physical structures and material properties can be imaged by processing the phase and amplitude values.
