A method for generating a data-bearing image is implemented by an encoding system including a halftoning module and an encoding module that stores encoding rules associated with respective codes. In the method, the halftoning module converts a grayscale image into a halftone image having a plurality of image cells each consisting of a plurality of dots, at least one of which is a first-tone dot and each of the rest of which is a second-tone dot. Afterward, the encoding module generates a data-bearing halftone image encoded with at least one of the codes by maintaining or changing the number of the first-tone dots in one of the image cells based on one of the encoding rules associated with the at least one of the codes.

A side grating based light coupling system comprises an optical fiber, a side grating disposed on one side of the lateral wall of the optical fiber, and a laser array disposed adjacent to the other side of the lateral wall of the optical fiber. The side grating comprises a plurality of grating elements arranged in a non-uniform arrangement. The laser array for generating a laser beam towards and passes through the optical fiber, and the laser beam is converted into at least one laser beam through the plurality grating elements. The diffraction efficiencies of the converted laser beams are different. The converted laser beams propagate inside the optical fiber based on total internal reflection. The plurality of grating elements of the side grating are heterogeneous arrangement without loading the optical collimating lens, and can reduce scattering loss by controlling the asymmetric diffraction efficiency, to improve optical coupling efficiency.

A ceramic cell structure includes an upper electrode layer, and a lower electrode layer. At least one electrolyte layer and at least one electron barrier layer are disposed between the upper electrode layer and the lower electrode layer. By changing the combination of the electrolyte layer and the, electron barrier layer disposed between the upper electrode layer and the lower electrode layer, the problem caused by conducting electricity via the electron which results in open circuit voltage drop and high temperature due to solely using electrolyte laser can be avoided. Conducting electricity via the electron can be prevented by adding the electron barrier layer with high ionic conductivity ratio. Besides, the ceramic cell can further increase the open circuit voltage and the power density above 700 C.

A modular fuel cell structure includes an anode conductive sheet, an air electrode sheet, a separating membrane, and a cathode conductive sheet stacked on a casing. The casing has a reaction vessel, and also has a first, a second, and a third flow passages, which all communicates with the reaction vessel, and are all independent. Said modular structure forms a fuel cell system with a first storage tank, a second storage tank, a retrieval device, and a feeding device which controls the first and the second storage tanks to deliver a first and a second materials to the casing. The first and the second materials are respectively injected into the reaction vessel for reaction through the first and the second flow passages, and then exhausted to the retrieval device through the third flow passage after the reaction. With the independent flow passages, the efficiency of power generation could be improved.

The present invention provides a method of searching for multimedia image. When a camera and a microphone are used for recording an image file, a software of speech recognition is used for converting the speech recorded by the microphone into a text file, and then the image file and the text file are combined to form a folder for storing into a data base. If a user wants to search for a certain image file, the data base is entered to search all folders, and a key word is used for searching the related text files so that the related image files are very easy to find.
