    • Novel proton exchange membrane fuel cells and direct methanol fuel cells with nanostructured components are configured with higher precious metal utilization rate at the electrodes, higher power density, and lower cost. To form a catalyst, platinum or platinum-ruthenium nanoparticles are deposited onto carbon-based materials, for example, single-walled, dual-walled, multi-walled and cup-stacked carbon nanotubes. The deposition process includes an ethylene glycol reduction method. Aligned arrays of these carbon nanomaterials are prepared by filtering the nanomaterials with ethanol. A membrane electrode assembly is formed by sandwiching the catalyst between a proton exchange membrane and a diffusion layer that form a first electrode. The second electrode may be formed using a conventional catalyst. The several layers of the MEA are hot pressed to form an integrated unit. Proton exchange membrane fuel cells and direct methanol fuel cells are developed by stacking the membrane electrode assemblies in a conventional manner.

    • A multi-network exchange system has a first type network (PSTN) and a second type network (Internet) and a multi-network exchange bridge in communication with the first and second type networks for the transfer of electronic information signals (telephone calls) between the first and second type networks. The multi-network exchange bridge apparatus facilitates transfer of electronic information signals to a portable access device or a gateway portal in communication with a node of one of second type networks from the first network. The multi-network exchange bridge has at least one multi-network instantiation device that enables the portable access device to function as a remote extension of the multi-network exchange bridge. A fixed address translation device provides conversion of a first address fixedly describing a node of the first type network to a second address or third address virtually describing nodes of the second type network.

    • The mainstream jet engine now is the turbo-jet engine. Here in this invention the turbine is replaced by a piston motor. This will increase fuel efficiency and separating the turning parts from the burning parts will benefit maintenance effort. Unlike traditional turbo-jet engine to use turbines to drive fans and compressors, this invention uses a rotary motor driven by high pressure fluid generated by separate working chambers piston engine to drive fans and compressorsSealing is a major issue in engine design. Without proper sealing between moving parts, the working media will loose pressure and the power output will be low. So tradition rotary engine has sealing problems due to its complex movement of pistons. Here a linear movement piston is used when the working media is gas and a rotary piston when the working media is fluid, thus solving the problems with sealing, cooling and lubricating difficulties.This invention uses some techniques developed in the previous inventions by me, application No. 60957442 and 11846550.
    • 主流喷气发动机现在是涡轮喷气发动机。 在本发明中,涡轮机被活塞马达代替。 这将提高燃油效率,并将转向部件与燃烧部件分离将有利于维护工作。 与使用涡轮机驱动风扇和压缩机的传统涡轮喷气发动机不同,本发明使用由单独的工作室活塞发动机产生的高压流体驱动的旋转电机来驱动风扇和压缩机密封是发动机设计中的主要问题。 运动部件之间没有适当的密封,工作介质将会松动压力,并且功率输出将会较低。 因此,传统的旋转发动机由于活塞的复杂运动而具有密封问题。 这里当工作介质为气体时使用线性运动活塞,当工作介质为流体时使用旋转活塞,从而解决了密封,冷却和润滑问题。 本发明使用我先前发明中开发的一些技术,申请号60957442和11846550。

    • A characterized cell library for EDA tools includes one or more mathematical models for each cell, and one or more preconditioning functions (and/or inverse preconditioning functions) for each mathematical model. Each mathematical model represents a performance parameter (e.g., delay, power consumption, noise) or a preconditioned performance parameter of the cell. The preconditioning functions convert an operating parameter (e.g., input slew, output capacitance) associated with the performance parameter into a preconditioned input variable for the mathematical models. In doing so, the preconditioning functions allow for more accurate modeling of complex data relationships without increasing the complexity (e.g., order and number of coefficients) of the mathematical models. Also, because the cell library can be substantially similar to conventional polynomial-based cell libraries except for the inclusion of preconditioning functions, preconditioning does not significantly increase storage requirements and conventional EDA tools can be readily adapted to use the preconditioned cell library.
    • 用于EDA工具的特征化单元库包括用于每个单元的一个或多个数学模型,以及用于每个数学模型的一个或多个预处理函数(和/或反向预处理函数)。 每个数学模型表示单元的性能参数(例如,延迟,功耗,噪声)或预处理的性能参数。 预处理功能将与性能参数相关联的操作参数(例如,输入转换,输出电容)转换为用于数学模型的预条件输入变量。 在这样做时,预处理功能允许复杂数据关系的更准确的建模,而不增加数学模型的复杂性(例如,系数的顺序和数量)。 另外,由于除了包含预处理功能之外,细胞库可以基本上类似于常规的基于多项式的细胞库,所以预处理不会显着增加存储要求,并且常规EDA工具可以容易地适应于使用预处理细胞库。
