20110194723 | Magnetic Diaphragm and Manufacturing Method thereof - An exemplary magnetic diaphragm is applied to an electro-acoustic transducer. The magnetic diaphragm has a base formed with a magnetic layer thereon by a film deposition method. The base with the magnetic layer thus has magnetism to interference with a magnetic circuit of the electro-acoustic transducer. A manufacture method of the magnetic diaphragm is also disclosed. | 2011-08-11 |

20110194725 | Novel Bit Pattern Design For Visible Watermarking - A watermarking system uses distinct bit patterns to identify a logic 0, a logic 1, and a marker bit, which demarcates segments of logic bit information. Marker bits, which are printed on both foreground and background areas of an image, outline message blocks. In message extraction, a preprocessing step removes any white boarders, identifies the best defined corner of a message block, crops the image, and rotates the image to place the identified corner at the top-left corner. Message extraction scans the rotated image in window segments of increasing size during multiple cycles. During each cycle, if a bit pattern cannot be identified as a data bit, then the size of the examined bit area is increased and rechecked to see it specifically is a marker bit. If no bit information can be definitively identified, then it is assigned a logic bit value based on a 50% random assignment. | 2011-08-11 |

20110194727 | IMAGE DATA PROCESSIG SYSTEMS FOR HIDING SECRET INFORMATION AND DATA HIDING METHODS USING THE SAME - An image data processing system includes an image input module, a bit map generation module and an encoding module. The image input module receives an image and secret information and obtains at least one gray-level image according to image. The bit map generation module generates a bit map image according to gray-level image and generates an ordered dithering block truncation coding (ODBTC) image according to bit map image and gray-level image. The encoding module generates an encoded gray-level image according to bit map image and secret information, wherein the encoding module divides gray-level image into image blocks, finds candidate blocks with close black and white pixel numbers among the image blocks, selects high frequency blocks belong to the high frequency region of the image from candidate blocks, and randomly embeds secret information into high frequency blocks to generate encoded gray-level image with secret information embedded therein. | 2011-08-11 |
