Abstract:
The present invention relates to a silicon optoelectronic device using silicon nanowire and a method for preparing the same. More particularly, the present invention relates to a silicon optoelectronic device using silicon nanowire, which is prepared by doping erbium (Er) into silicon nanowire and form a silicon dioxide sheath on the surface of the silicon nanowire by oxidation, so that the diameter of the silicon nanowire is reduced to give quantum confinement effect and photoelectric transition effect, and a method for preparing the same. When an electric current is applied, light emitted by the photoelectric transition effect of the silicon nanowire excites and decays the doped erbium to effectively emit light having a wavelength of about 1.5 μm. The silicon dioxide sheath effectively amplifies the light by the microcavity effect of the silicon nanowire.

The battery pack locking apparatus includes a mounting groove formed at a prescribed position of the rear casing frame, a push locker unit mounted in the mounting groove such that the push locker unit can be moved toward the front and the rear of the terminal body when the push locker unit is pushed, a slide locker unit coupled with the push locker unit at the lower part of the push locker unit such that the slide locker unit can be slid toward the upper and lower ends of the terminal body, as the push locker unit is moved toward the front and the rear of the terminal body, for locking the battery pack to the battery pack locking space or popping the battery pack out of the battery pack locking space when the battery pack is unlocked from the battery pack locking space, and a coil spring mounted to the slide locker unit for providing an elastic force so that the push locker unit is moved toward the front and the rear of the terminal body and the slide locker unit is slid toward the upper and lower ends of the terminal body.
Abstract:
The present invention relates to an improved pitch modification method by glottal closure interval extrapolation. It is an object of the present invention to modify pitches of speech signals by the glottal closure interval extrapolation and to maintain quality of the modified speech, when concatenating original speech segments to synthesize speech. An input speech signal is converted into a digital speech signal. A glottal closure interval is detected in the digital speech signal so as to estimate vocal tract parameters by using pitch synchronous analysis. Vocal tract characteristic signals of the glottal closure interval and glottal characteristic signals of a glottal open interval are separated from each other according to the detected glottal closure interval. The separated vocal tract characteristic signals are extrapolated and reduced to a desired pitch length by the estimated vocal tract parameter. The extrapolated and reduced vocal tract characteristic signals are overlapped and added to the separated glottal characteristic signal so as to generate a synthetic speech signal which varies in a desired pitch length.

Abstract:
A method of formatting and normalizing continuous lip motions to events in a moving picture besides text in a Text-To-Speech converter is provided. A synthesized speech is synchronized with a moving picture by using the method wherein the real speech data and the shape of a lip in the moving picture are analyzed, and information on the estimated lip shape and text information are directly used in generating the synthesized speech.
Abstract:
A battery pack locking apparatus for a mobile telephone is disclosed, in which a locker is operable with its own mechanical structure without using a separate spring. The battery pack locking apparatus includes a locker movable in a perpendicular direction with respect to a body of the mobile telephone and mounted on a lower casing frame of the mobile telephone, and an elastic member formed on a lower surface of the locker to provide a restitution force to the locker. The elastic member is a zigzag tension rib, which is formed extending downward from the lower surface of the locker such that a free end of the tension rib should be pressingly contact the lower casing frame.
Abstract:
A fast search method for LSP (Linear Spectrum Pair) quantization is provided. The fast search method in accordance with an embodiment of the present invention includes the following steps. A first step is obtaining a target vector and a code vector. The target vector and the code vector are converted for ordering property. A second step is generating a code book having the ordering property for sub-matrices by utilizing the target vector and the code vector. A third step is selecting a particular line for determining a search scope in the code books and sorting the code book in descending order with respect to component values of the particular line. A fourth step is determining the search scope by utilizing the ordering property of the target vector and the sorted code vectors. The fifth step is obtaining an error standard by utilizing the target vector and the code vector, and obtaining an optimal code vector by utilizing the error standard within the determined search scope.
