    摘要： A hybrid watermark insertion method includes the steps of dividing the digital image into a low frequency region and a high frequency region using an edge map of the digital image; inserting a watermark into the low frequency region of the image by employing a watermarking method using a human visual system (HVS); and inserting the watermark into the high frequency region of the image by employing a quantization index modulation (QIM) method. A hybrid watermark extraction method includes the steps of estimating a reference value used when inserting a watermark, and searching a maximum value of correlation coefficients in an image of the watermark image while changing the estimated reference value within a designated range, to thereby find out the watermark insertion method. Accordingly, the watermark insertion method can be easily identified, thereby enabling the watermark extraction in a more readily manner.

    摘要： A memory comprising a plurality of memory blocks having a plurality of memory cells and wordlines, each of the memory blocks having selection lines by which the memory blocks are selected. The selection lines are shared between neighboring blocks. In addition, a wordline switching circuit is coupled between conductors carrying wordline drive signals and the wordlines, and a block selection line circuit is coupled between conductors carrying the block selection lines signals and the block selection lines. A selection control circuit supplies selection control signals to the wordline switching circuit and the block selection line switching circuit. The selection control circuit generates the selection control signals in response to address informing signals. The selection lines are coupled to discharge circuits, which pull down voltage levels of selection lines that are not selected.

    摘要： A hinge device for connecting a main body and a display unit of a portable computer includes a projection, a hinge member, and attachment units. The projection extends from a lower edge of the display unit, and the hinge member extends outwardly from both sides of the projection and connects to respective attachment units. A groove for receiving an end portion of hinge member is formed in each attachment unit. Each groove has a shape that is complementary to the shape of the end portion of the hinge member, so that the end portion of the hinge member easily inserts into the groove. In a preferred embodiment, one attachment unit is fixedly installed on the main body of the computer, and the other attachment unit is detachably connected to the main body. The attachment units and projection define a pivot axis about which the display unit rotates relative to the main body.
