Abstract: A decoder, a projecting system, and a method for processing an image thereof are provided. The decoder is adapted to the projecting system having a projecting module and a shutter glass. The decoder includes a decoding circuit and an indicating unit. The projecting module outputs a frame turning control signal to the shutter glass. The decoding circuit receives and decodes a three-dimensional (3D) video signal to produce a first image data and a second image data to the projecting module. The indicating unit is coupled to the decoding circuit and correspondingly produces an indicating signal when the decoding circuit outputs one of the first image data and the second image data.

Abstract: A frequency synthesizer of a transceiver for generating a crystal oscillation frequency and a carry frequency having been done a process of frequency offset cancellation with that of another transceiver. The frequency offset cancellation of the frequency synthesizer is done in accordance with a wireless signal which is transmitted from another transceiver received. The frequency synthesizer has a first sigma-delta modulator receiving a signal transmitted by a transceiver at far area responding thereafter a frequency divisor value in accordance with the channel information of the received signal and a frequency offset between two.

Abstract: Methods and devices for catalyzing reactions, e.g., in a metal-air electrochemical cell, are disclosed. In some instances, a porous positive electrode of the metal-air electrochemical cell includes a metal to catalyze a reaction at the electrode (e.g., oxidation of one or more metal-oxide species). The metal can be disposed as nanoparticles, and/or be combined with a second metal. Other aspects are directed to devices and methods that can generally promote a chemical reaction (e.g., an oxidation/reduction reaction) such as the formation of platinum containing nanoparticles that can be used to catalyze electrochemical reactions.

Abstract: A projection apparatus including an illumination system, a light valve, and a color filtering module is provided. The illumination system is capable of emitting an illumination beam. The light valve is disposed in the transmission path of the illumination beam and capable of converting the illumination beam into an image beam. The color filtering module is disposed in the transmission path of the illumination beam between the illumination system and the light valve and includes a plurality of colored filters and a gray filter. The gray filter is capable of reducing the intensity of the illumination beam passing through the gray filter. An image adjustment method is also provided.

Abstract: An image display method adapted for a digital display apparatus is provided. The image display method includes the steps of: first, detecting a maximum average picture level of each picture displayed by the digital display apparatus; judging whether the maximum average picture level is larger than a reference value; determining a displaying mode of each picture according to the judgment. The image display method is adapted for improving the displaying quality of a digital display apparatus.

Abstract: A system and method for removing digital watermarks from a watermarked image of an electronic device are provided. The method decomposes the watermarked image to a plurality of Eigen-images, assigns an identifier to each of the Eigen-images in sequence, and identifies an identifier range of the Eigen-images to be removed from the watermarked image. The method further selects Eigen-images having watermarked information from the identifier range, deletes the Eigen-images having watermarked information from the Eigen-images within the identifier range, and integrates the remainder Eigen-images of the identifier range to form a composite image. Additionally, the method determines whether the composite image is distorted, and stores the composite image into a storage device of the electronic device if the composite image is not distorted.

Abstract: A biosensor structure and a method for fabricating the same are described. The biosensor structure for detecting at least a single cell includes a substrate with an insulating surface, a conductive layer and a plurality of capture molecules. The conductive layer is disposed on the substrate, and has a first pattern and a second pattern separated from each other. The first pattern includes a plurality of first finger configurations, and the second pattern includes a plurality of second finger configurations, so as to form interdigitated array. The capture molecules are immobilized on the conductive layer, such that the cell that is bound specifically to the capture molecules on two adjacent first and second finger configurations is detected. The biosensor structure is feasible for real-time (<3 min), specific, and quantitative targeted cell detection down to a single cell.

Abstract: Playback control methods and systems are provided. At least one picture is obtained. The picture corresponds to a frame, and the picture includes a first region and a second region adjacent to the first region. It is determined whether at least one pixel in the first region has a predefined color, and whether at least one pixel in the second region has the predefined color. When the pixel in the first region has the predefined color and the pixel in the second region does not have the predefined color, the first region is removed, and the second region is enlarged to cover an original position of the first region. The enlarged second region is then played back via an anamorphic lens.

Abstract: A method and an apparatus for bit-rate enhancement and a wireless communication system using the same are disclosed. According to the present invention, two approaches are provided for bit-rate enhancement: one is an increase of chip-rate and the other is a decrease of chip number associated with on symbol. As such, the transmission bit-rate can be enhanced significantly so as to facilitate the applications of wireless voice communications or security.
