Generally speaking, the medical treatment of rehabilitation has been doing by physical therapist by providing patients with external forces rehabilitation assistance as far as we know currently. For the purpose of both of reducing the workload of physical therapists and providing the quantitative data obtained during the rehabilitation process so as for physical therapist’s reference. This research will build an automatic finger stretch and grip control system by using the Human- Machine Interface for operation control. It can be done by physical therapist or physical doctor to set the operating conditions so as to help the patients with their finger joints motion so as to achieve the rehabilitation effect of their fingers. This research is trying to integrate the mechanism and control technology mainly. With regards to the control technology, it uses a micro chip so as to lead the motions of the stretch & grip for finger rehabilitation by a signal processing control servo motor. And its operation interface is using an embedded system along with Visual Studio compiling software so as to touch input the operating conditions. The system operation functions are including single finger joint motion orsynchronized actuation of all fingers and the setting of the cycle numbers. Furthermore, in order to soften the finger tendons so as to promote the rehabilitation effect during the rehabilitation process, the system adds external steam in so as to control the internal temperature & humidity of the rehabilitation box and apparently, the whole finger automatic stretch & grip control system will be better owing to it.

Because it does not lose sensitivity to spacecraft declination when the spacecraft is near earth's equatorial plane, as is the case for Doppler tracking. As a working mode, DOD measurement can acquire differential doppler information which is an important observation value used for orbit determination. To perform DOD tracking, the spacecraft needs to transmit high frequency sinewave tone which is usually specially designed. In this paper, we discussed algorithm of DOD measurement using traditional ranging tones. And experiment was performed with ranging tone of China CE'2, data was recorded with baseline which is combined with Shanghai station and Beijing station. Theoretical analysis testifies high accuracy of our algorithm.
Simplification of the Parametric Transformation Equations for Analysis of Plane Stress
Authors: Du Mao Lin , Chen Guo Liang , Pu Kui Ying
Published: November 2012

For the analysis of plane stress, there are two methods, transformation of equation and Mohr’s circle. With the former method, the two principle angles are found by taking derivative to determine the extreme value of stresses. However, it is unknown which one of the two principle angles corresponding to the maximum stress. Moreover, the relationship between the two methods is inexplicit, as the angle of the rotation of the element is eliminated to derive the equation of Mohr’s circle. Using trigonometric relations, considering two systems of sign conventions for shear stresses, simplified parametric transformation equations are obtained. A unique principle angle is easy to be found corresponding to a principle stress. It is obvious that the graph of the simplified equations is a circle. The relationship of the angle of the rotation of the element and the angular parameter of the circle is explicit.

The revolving jet is a technique method of using the water to eliminate shallow submersion land mine surface, it can be also used in the clearance of mine, the unique characteristic is the main use of shear broken, erosion crushing, stretch broken cyclone grinding effect on the topsoil which is on shallow mines. this technology research and the application. Based on the revolving water jet flow theory and soil mechanics theory, by means of the action of the jet flow to the soil body surface and the mechanism of the revolving jet flow breaking ground analysis, and the thoughts of which the action pressure of jetting is basic external factor of the soil body destruction, but the soil body critical destructive power to soil body is determined by its internal factors that physical and mechanical properties of the soil, only then, when the jet flow action is greater than the soil body the critical destructive power, the soil body only then possibly has the destruction. This technology research and the application not only raise efficiency of the mine clearance, but also further expand application scope of the water Jet. Based on water jet test platform of the laboratory, in order to make the revolving jet produce the greatest ground-breaking efficiency. the swirling jet nozzle and rotating components are optimized for it.

Electrical discharge machining has the capability of machining all conductive materials regardless of hardness, and has the ability to deal with complex shapes. However, the speed and accuracy of conventional EDM are limited by probability and efficiency of the electrical discharges. This paper describes a three degrees of freedom (3-DOF) controlled, wide-bandwidth, high-precision, long-stroke magnetic drive actuator. The actuator can be attached to conventional electrical discharge machines to realize a high-speed and high-accuracy EDM. The actuator primarily consists of thrust and radial magnetic bearings, thrust and radial air bearings and a magnetic coupling mechanism. By using the thrust and radial magnetic bearings, the translational motions of the spindle can be controlled. The magnetic drive actuator possesses a positioning resolution of the order of micrometer, a bandwidth greater than 100Hz and a positioning stroke of 2mm.

Elastomeric polymers have been used as moulds for fabricating micro structures in the soft lithography technology due to their elastic features and unstickiness to polymer features. Previously, the micro moulds were normally produced by imprinting on micro prototypes, which are fabricated using deep reactive etching or photolithography. In this paper, we introduce a direct mould fabrication method, which uses pulsed laser drilling technology to directly generate high aspect ratio patterns in elastomeric polymers. The effects of laser parameters such as pulse repetition rate and average power on the drilling qualities are systematically studied. The techniques presented in this paper would provide a more flexible way to fabricate high aspect ratio micro features on elastomer mould efficiently.

Published: November 2012

This paper presents an experimental study in milling of SiCp/Al composites on a high precision machine by using chemical vapor deposition(CVD) diamond coated tools and polycrystalline diamond (PCD) tools. The tool wear was observed and measured by an optical microscope and a scanning electron microscope (SEM). The results show that the coating rupture causes the failure of the CVD diamond coated tools. The PCD tools’ wear is less. At the relatively low cutting speed, the wear pattern of PCD tools is the flank wear which caused by the abrasion of SiC particles. Due to the low cutting temperature, the graphitization of PCD tools does not happen. The wear mechanism of PCD tools will be the abrasive and adhesive wear.

In recent years, global economic development has led to rises in crude oil prices and the greenhouse effect. Developing renewable energy has become a major issue internationally. Biomass energy is one form of renewable energy. Biomass enery as a transportation fuel can be deliverd from fats, starch biomass fuel or biofuel, and cellulose biofuels. Because concerns exist that fats could lead to a food crisis, most nations have focused on researching and developing cellulose. In this study, we used coffee bean residue as a fuel source. We employed the pyrolysis process to produce pyrloysis oil products. We also used appropriate emulsion technology and suitable amounts of petroleum diesel for adding coffee bean residue to investigate the influence that coffee bean residue pyrolysis oil with low-add ratios (5 vol. %) has on diesel engine performance. The results indicated that coffee bean residue pyrlosis oil with low-add ratios resulted in an earlier diesel engine ignition time. Additionally, at low rpms, the diesel engine’s indicated specific fuel consumption (ISFC) was relatively low. However, ISFC was superior at higher rpms. In summary, when adding a portion of coffee bean residue pyrlosis oil to diesel engines, performance was superior during high-rpm operations compared to lower rpm. Pollutant emissions were also significantly improved. The results of this study can provide a reference for future high-add ratios and high-load engine tests.
