A system and method of designing digital system. One aspect of the invention includes a method for designing an essentially digital system, wherein Pareto-based task concurrency optimization is performed. The method uses a system-level description of the functionality and timing of the digital system. The system-level description comprises a plurality of tasks. Task concurrency optimization is performed on said system-level description, thereby obtaining a task concurrency optimized system-level description, including Pareto-like task optimization information. The essentially digital system is designed based on said task concurrency optimized system-level description. In one embodiment of the invention, the description is includes a “grey-box” description of the essentially digital system.

A fuel container is disclosed, which is used for supplying fuel to a fuel cell. The fuel container, adapted for supplying fuel to a fuel cell, is composed of a tank and a cover covering the tank, in that the tank is further comprised of: a first reservoir for accommodating a methanol solution; and a second reservoir for accommodating the water generated during the operating of the fuel cell and the water to be replenished therein. The fuel container of the invention not only is capable of storing and supplying fuel to a fuel cell, but also is capable of recycling the water generated during the operating of the fuel cell to be used as replenishing water. Moreover, the replacing of water and methanol can be accomplished at the same time as the fuel container is replaced, so that the space utilization of fuel cell can be rationalized and optimized for enhancing the usability and convenience of the fuel cell.

This invention provides a method and system for decrypting an optical disc. The contents of the optical disc are encrypted, and the decrypting information is stored in the Internet server. The decrypting information is created by the internet server in terms of the request, including two layers of data, the first layer contains the information related to the data of the optical disc which can not be copied, the second layer contains the encrypted method for decrypting the optical disc. When the optical disc player receives the decrypting information, firstly, it acquires the data from the optical disc to be played which can not be copied according to the information of the first layer, and then decrypts the data of the second layer using the data which can not be copied, thus to acquire the method for decrypting the optical disc and the related parameters.

A method for manufacturing membrane electrode assembly of fuel cell includes positioning an ion exchange membrane that is cleaned and trimmed to a predetermined size in advance to a base plate, mounting the base plate to a printing platform, attaching a printing plate to the platform, coating a catalyst solution on the printing plate with a scraper, printing the catalyst solution onto the ion exchange membrane with the scraper, heating the ion exchange with a heating board to a temperature of 70-80° C., and waiting for the ion exchange membrane to return flat to complete the coating of the catalyst solution on the ion exchange membrane. The printing and heating steps are repeated for both anode and cathode of the ion exchange membrane. The ion exchange membrane is further subject to hot pressing and then a piece of carbon cloth is positioned on the catalyst coating to serve as a diffusion layer. This completes the manufacturing of the membrane electrode assembly.

A captive screw (80) is provided for attaching two sheets together. The captive screw includes a screw (40) and a cap (50). The screw includes a head (41), a threaded shank (43), and a flange (42) located between the head and the shank. The cap includes a cavity (51) and a skirt portion (53). The shank forms a plurality of ribs (52) on an underside thereof. The flange forms a plurality of vertical ridges (44) therearound. The cap and the screw are combined, with the head and the flange tightly fitted in the cavity. The shank extends out of the skirt portion, with cylindrical space defined therebetween. A rod portion of a complementary engaging rivet can then be received in the space.
