Abstract: Provided is a binder for a secondary battery including a copolymer including repeating units of the Chemical Formula 1, Chemical Formula 2, Chemical Formula 3, and Chemical Formula 4 disclosed herein. When the binder for a secondary battery is applied to a negative electrode and a secondary battery, expansion of the negative electrode may be effectively suppressed. Furthermore, the binder for a secondary battery has improved adhesion to effectively suppress exfoliation and desorption of a negative electrode, thereby manufacturing a secondary battery having significantly improved charge/discharge cycle characteristics and battery performance by using the binder.

Abstract: The present disclosure provides a waveguide display apparatus. The waveguide waveguide display apparatus of the present disclosure is a waveguide display apparatus for correcting curved surface reflection distortion, the waveguide display apparatus including a waveguide for guiding light inputted from the outside; a first diffractive optical element disposed at the waveguide, and diffracting the light inputted from the outside to the inside of the waveguide; and a second diffractive optical element disposed at the waveguide, and diffracting the light guided by the waveguide to output a plurality of diffracted lights in a direction of a curved surface reflector located outside, wherein the second diffractive optical element has a structure of a diffraction grating corresponding to a curvature of the curved surface reflector such that the diffracted lights are reflected at different locations of the curved surface reflector in directions parallel to each other.

Abstract: A method for replicating a holographic optical element and a holographic optical element replicated thereby are provided. The holographic optical element is larger than a master. The master has a holographic grating pattern generated on the master by interference of the reflected, diffracted or transmitted beam generated by irradiating the master having a specific diffraction grating pattern formed thereon with a laser beam.

Abstract: A system and method for laser assisted bonding of semiconductor die. As non-limiting examples, various aspects of this disclosure provide systems and methods that enhance or control laser irradiation of a semiconductor die, for example spatially and/or temporally, to improve bonding of the semiconductor die to a substrate.

Abstract: An apparatus for and method of handling a failure in reading motion picture data from a storage medium and reproducing the same includes a media-type distinguishing unit determining whether a storage medium to be reproduced is a motion picture medium; and a reading failure handling unit controlling a pick-up to shift positions on the motion picture medium and read data from a position arrived at by shifting, whenever a failure in reading the motion picture medium occurs.

Abstract: An apparatus and method for high-speed interfacing between ICs are provided. A generator generates space clock pulses by adjusting a data rate of data. An inserter inserts commas during the space clock pulses. And a transmitter transmits bit streams with the data and the commas to a receiving IC. Accordingly, data can be transmitted and received at high rates between ICs.

Abstract: An apparatus and method for discriminating an FFT (Fast Fourier Transform) mode and a guard interval mode and detecting the start point of a useful symbol so that a receiver can carry out an FFT operation.

Abstract: Disclosed is a CDMA (Code Division Multiple Access) code timing tracking apparatus capable of exact code timing synchronization without regard to signal gain change by normalizing signal gain to synchronize code timing. The CDMA code timing tracking apparatus correlates each code generated from a PN code generator, which generates on-time code, early code being faster than the on-time code and late code being later than the on-time code, with CDMA signal, low-pass filters output signal of a plurality of correlators with first to third low-pass filters and quantizes output signal of the first low-pass filter.
