Abstract: Disclosed herein is a spectacles and sunshade clip assembly using magnets. The magnets serve to detachably attach the sunshade clip to the spectacles. The spectacles comprises a pair of lens frames connected to each other by means of a nose bridge, and temple arms connected, respectively, to the lens frames by means of magnetically-induced hinges. The sunshade clip comprises a pair of sunshade lenses formed by cutting a colored plastic plate into a desired lens form, and a sunshade bridge formed by injection molding and adapted to connect the sunshade lenses to each other. Two magnet ribs are coupled to opposite outer ends of the sunshade lenses to extend in opposite directions. Each of the magnet ribs is configured to substantially coincide with the outer contour of the hinge provided at the spectacles and has a magnet mounted to face the hinge.

Abstract: The present invention relates to a device for compensating a radio frequency distortion caused by a sample/hold operation of a digital/analog converter in an orthogonal frequency division multiplexing (OFDM) transmission system, and a method thereof. In a digital transmission system, an edge frequency signal of a transmission signal band is distorted by a sample/hold operation of a digital/analog converter such that a signal attenuation is generated at a frequency domain by a sync function having a zero point at a sample frequency of a transmission signal. In the present invention, the signal distortion may be compensated by multiplying a coefficient of an inverse sync function by a signal weight value at the frequency domain, and it may be compensated by using a single multiplier and a lookup table storing the coefficient of the inverse sync function.
