Artificial anal sphincter with sensor feedback powered by transcutaneous energy transmission

This artificial anal sphincter (AAS) is used to help patients who are in severe incontinence. It consists of two parts. The first part is taken outside with patients. The second is implanted in the bodies to provide independent evacuation for patients. It is powered through transcutaneous energy transmission by the first part. There are two sensors in the second part. One sensor measures the pressure in the cuff-clamp around the recta. The other measures the pressure of the recta. As soon as the pressure measured by the later reaches the threshold, a signal is sent out to patients through wireless communication to alarm patients preparing defecation. Patients can give a start signal to begin defecating after they are ready. And they can also give a signal to stop defecating like a healthy person. With the aids of the novel medical device, patients can defecate as a healthy person. The first generation of this AAS is presented.     

Reflections on energy issues in China

Energy, which has a bearing on both economic and national security, is of importance and a major constraining factor to the economic and social development of China. The article analyses the current worldenergy status and development trend from the perspectives of resources, production and consumption and in thecontext of its implications on the environment and economic and social development, and explores opportunitiesand challenges for China's energy development. With a focus on the strategy of energy development in China,the author proposes a new energy development approach with Chinese characteristics whose main elementsare: energy-saving, high-efficiency, diversified development, environment protection, technology guidance andinternational cooperation. In other words, China is striving to build a reliable energy production, circulationand consumption system that is efficient, technologically advanced, low polluting and ecologically friendly. Along-term development strategy with priority on energy conservation, efficient utilization of primary energyand advanced electricity system is expounded in the paper. The author also describes the prospect of energytechnology development and stresses the implementation of energy strategy by further improving energy policyand related mechanisms, strengthening macro-management and the essential role of the market in resourceallocation so as to ensure the economic and social development of China through reliable energy supply.

The evaluation of transportation energy efficiency: An application of three-stage virtual frontier DEA

In this paper, transportation energy efficiency is newly defined and its inputs and outputs are obtained through literature review. Labor input, capital input and energy input are selected as the inputs, passenger turnover volume and freight turnover volume are defined as the outputs. A new model—three-stage virtual frontier DEA (three-stage virtual frontier Data Envelopment Analysis) is proposed to evaluate transportation energy efficiencies. The case of thirty Chinese PARs (provincial administrative regions) from 2003 to 2012 is applied to verify its rationality. In the three-stage virtual frontier DEA, the reference DMU (decision-making unit) set and the evaluated DMU set are two different sets so that it can distinguish the DEA efficient DMUs. And in the evaluating process, the reference DMU set remains unchanged to assure its results more reasonable than Super DEA model. The results show that transport structure and management measures have important impacts on transportation energy efficiency.

InnoTrans2010展览会展示最佳产品(待续)

在处于金融经济危机高潮中的InnoTrans 2008展览会上,许多人坚持认为,运输业的衰退将经历好多年,因为铁路部门不得不放弃签订新的合同和巨额的基础建设项目。在一些国家,发生的情况就是这样,但是,就是在危机时期整个铁路部门却得到了国家的强力支持。最明显的例子就是中国。在中国,新的铁路线建设正在加速进行,而最为现代化的机车车辆则正在大量采购。此外,在许多国家,铁路部门的新项目已经被搁置,但未被放弃。因此,在今后的几年中,可以预期,铁路和城市轨道交通部门会有数以十亿计的投资。有鉴于此,在InnoTrans 2010展览会上,所有的指标都创出了新的纪录。文章对这次铁路技术装备的大检阅作出详细的介绍。     

Investigation of a passenger car's dynamic response due to a flywheel-based kinetic energy recovery system

With the advent of flywheel-based kinetic energy recovery systems in automotive applications new safety issues arise as a consequence of the flywheel's high rotational speed. While the special structural safety requirements of the components are well discussed in the literature, there is still little research on the influence of gyroscopic effects on vehicle dynamics. The aim of this paper is to investigate the influence of a typical high-speed flywheel on the driving dynamics of an average passenger car. To this end the equations of motion of a gyroscope are derived, which relate the vehicle's roll, pitch and yaw rate with the transverse torque acting on the flywheel. These equations are implemented in a commercial vehicle dynamics simulation program in order to determine the reaction torques acting on the vehicle within a representative range of driving situations. Numerical simulations indicate that the gyroscopic effect can be considered insignificant in standard driving situations.
