Thus, the real-time stereo tracking is required to ensure that the stereo measurement process and the end-effector��s motion are as synchronized as much as possible. The Multimedia Extension (MMX) technology [6] is utilized in this paper more to minimize the computational cost of the stereo tracking process. In addition, the stereo depth estimation will be calibrated by the linear encoder measuring results on a straight-line moving pneumatic cylinder. Therefore, the correctness of stereo vision system can be known. For that, a test rig is set up for realizing the developed strategies of the stereo vision which is used to measure the end-effector of the three-axial pneumatic parallel mechanism robot arm.2.

Methanol is a more feasible liquid fuel for use in a reformer owing to its high Inhibitors,Modulators,Libraries safety of storage and transport, high carbon/hydrogen ratio, high power density and low reforming temperature (250�C300 ��C) [1]. However, the technology application-related problems related to its use include starting time and power density. Also, how to produce hydrogen efficiently and steadily is another important concern.The ability of the proposed micro sensor to monitor the inner environment of a micro methanol reformer requires the following features: a high sensitivity, short response and recovery time, reproducibility and long stability, low interference (high selectivity), simplified process and mass production capability, wide monitor range, low cost, and Inhibitors,Modulators,Libraries low energy waste.
Liu and Yang have used polyimide as the substrate material for a flow sensor [2,3], while Chuang fabricated a micro temperature sensor and micro heater on poly-dimethylsiloxane (PDMS) film [4]. Bielska [5] used polyamide foil as the basic material and fabricated gold and copper electrode on it by using micro-electro-mechanical systems (MEMS) technology. The temperature is evaluated Inhibitors,Modulators,Libraries at a range of 30 ��C to 42 ��C, and the resistance change is used based on the temperature to study its linear outcome.Zhang [6] fabricated platinum/titanium on Pyrex 7740 glass based on the use of MEMS technology, while simultaneously using the heater as temperature sensor. Platinum and titanium are then deposited using an E-beam evaporator, followed by completion of the sensor shape by using the lift-off Inhibitors,Modulators,Libraries method.
Based on use of Brefeldin_A MEMS technology, Shih [7] fabricated platinum/titanium on a silicon wafer to be used in temperature gradient interaction chromatography, in which a layer of parylene is deposited around the sensor to become selleck Trichostatin A an air gap to increase thermal isolation and decrease heat loss.Yan [8] used nickel-chromium alloy as the material of a micro heater and nickel as the material for a temperature sensor. An electron probe micro analyzer was also used to evaluate the adhesion between nickel and the substrate material when depositing nickel on different substrate materials.
