    • An apparatus and method for preventing illegitimate distribution of digital contents on Internet obtains a first wavelet image having a user information-embedding region by performing a wavelet transformation (WT). The user information embedding region of the first wavelet image is wavelet-transformed to obtain a second wavelet image composed of a discrete cosine (DC) region and high-frequency regions second wavelet image. A high-frequency components removed image is obtained by removing high-frequency components in the high-frequency regions of the second wavelet image, and subjected to an inverse WT (IWT) to be outputted as an IWT image. A user information embedding unit embeds user information to the IWT image, wherein data of the user information are sequentially embedded to positions where a difference value between the user information embedding region and the new user information embedding region is small, to thereby reset the user information embedding region as the user information.
    • 用于防止数字内容非法分发的装置和方法通过执行小波变换(WT)获得具有用户信息嵌入区域的第一小波图像。 第一小波图像的用户信息嵌入区域进行小波变换,得到由离散余弦(DC)区域和高频区域第二小波图像构成的第二小波图像。 通过去除第二小波图像的高频区域中的高频分量并获得作为IWT图像输出的逆WT(IWT)来获得高频成分去除图像。 用户信息嵌入单元将用户信息嵌入IWT图像,其中用户信息的数据被顺序地嵌入到用户信息嵌入区域和新的用户信息嵌入区域之间的差值小的位置,从而重置用户信息 嵌入区域作为用户信息。

    • Disclosed herein is an SoC-based core scan chain linkage switch. The core scan chain linkage switch includes test bus terminals, scan chain input/output terminals, a switch unit and SCLK, UCLK, Mode and Enable signals. The test bus terminals apply instructions and input/output test data. The scan chain input/output terminals link with the scan chains of an embedded core. The switch unit completes a linkage configuration between the test bus terminals and the scan chain input/output terminals in response to the applied instructions. The SCLK, UCLK and Mode signals apply the instructions to dynamically reconfigure the switch unit and update the linkage configuration of the switch unit, and the Enable signal activates and deactivates the switch unit.

    • A cup holder for a vehicle is mounted in the vehicle for supporting a cup. The cup holder includes a housing mounted on a wall portion of the cup holder, which has a receiving groove for receiving a cup. The housing includes a first guide groove formed therein, a guide movably mounted in the housing so as to enter and exit from the first guide groove, the guide having a second guide groove corresponding to the first guide groove, and a spring for restricting the guide from entering and exiting from the first guide groove of the housing. Even if excessive force is applied to the cup guide when the cup is inserted into the cup holder, an upper portion of the guide is prevented from departing from the housing, so that the cup holder can safely support the cup.
    • 用于车辆的杯架安装在用于支撑杯子的车辆中。 杯架包括安装在杯架的壁部上的壳体,该壳体具有用于容纳杯子的容纳槽。 壳体包括形成在其中的第一引导槽,可移动地安装在壳体中以从第一引导槽进出的引导件,具有与第一引导槽对应的第二引导槽的引导件和用于限制引导件的弹簧 从壳体的第一引导槽进入和离开。 即使当杯子插入杯架中时,过大的力施加到杯形导向件,也可以防止导向件的上部离开壳体,从而杯架可以安全地支撑杯子。
