20100321521Method of automatic white-balance calibration - Provided is a method of automatic white-balance calibration. The method firstly uses a predefined gain. Each color value for pixels of an inputted image is calculated. A number of the placements representing the pixels within each gray region of a color space are then obtained. Next, a new gain is obtained by linearly combining those placements. Further, in order to overcome a possible chromatic aberration on account of the overlapping regions in the color space, the method introduces a specific deletion ratio to delete a portion of placements positioned in the overlapping regions. Therefore the method provides a proper image. Furthermore, users may decide a level of the chromatic aberration by adjusting the predefined gain.12-23-2010

20110032048FILTERING DEVICE AND DIFFERENTIAL SIGNAL TRANSMISSION CIRCUIT CAPABLE OF SUPPRESSING COMMON-MODE NOISES UPON TRANSMISSION OF A DEIFFERENTIAL SIGNAL - A filtering device is capable of suppressing common mode noises upon transmission of a differential signal, and includes a differential transmission line, a grounding layer, a dielectric unit and a conductive structure. The differential transmission line has a pair of conductive traces spaced apart from each other. The grounding layer is spaced apart from the differential transmission line. The dielectric unit is disposed between the differential transmission line and the grounding layer. The conductive structure is embedded in the dielectric unit, is coupled electrically to the conductive traces and the grounding layer, and cooperates with the differential transmission line, the grounding layer and the dielectric unit to form a stacked structure that has an effective negative permittivity, thereby suppressing the common mode noises coupled to the conductive traces. A differential signal transmission circuit is also disclosed.02-10-2011

20090195982ELECTRONIC APPARATUS AND FAN MODULE THEREOF - The invention discloses an electronic apparatus and a fan module thereof. The fan module includes a base, an impeller, a liquid container, an atomizing device and a cover. The impeller is provided in the base. The liquid container is placed at the center of the impeller, and the liquid container contains a liquid. The atomizing device is disposed on the liquid container, and the atomizing device can atomize the liquid to form a mist to spray in order to absorb the heat in the electronic apparatus. The cover covers the base and forms an air outlet with the base. Furthermore, the cover has an air inlet. When the impeller rotates, the blade of the impeller drives airflow mixed the heated mist to enter into the base through the air inlet of the cover, and to exit from the base through the air outlet.08-06-2009
