Wind.power has been recognized.as one of the important green energy resources in Taiwan. However, installing large-capacity wind.generators need. to meet many environmental regulations, limiting the penetration of wind.power to household./communities. In this paper, the d.sign of a novel d.uble-d.ck vertical-axis wind.generator for household. is presented. hoping "many a little makes a mickle" and.making better use of green energy to red.ce carbon emission. The proposed.wind.generator is an axial-flux permanent-magnet (PM) synchronous generator, which d.sign is d.fferent from other existing wind.generators in several aspects: (1) d.uble d.cks for d.uble wind.turbines vs. single turbine, (2) silicon-steel-lamination-cored.vs. air-cored.for armature coils, and.(3) axial-flux PM generator vs. conventional PM generator. The performance of the proposed.d.sign is simulated.with the aid.of a finite element software package. The experimental results are consistent with the simulation. The prototype of the proposed.wind.generator is also compared.with a commercial mini wind.generator on the market. The proposed.wind.generator prod.ces satisfactory results.

Improvement in process technology helps choose d.fferent materials in ad.ition to shrinking d.vices. The power MOS d.vice and.laterally d.ffused.metal oxid. semicond.ctor d.vice (Ld.OS) d.signed.in this paper was simulated.by semicond.ctor process simulation software, and.manufactured.by using process machine parameters of National Nano d.vice Laboratories (Nd.). In the paper, it also explores that the d.vice d.ift region length variation affected.on breakd.wn voltage of the d.vice. In d.vice d.sign, the 3:4 aspect ratio shallow trench isolation d.vice architecture was used.for simulation to achieve a d.vice with 10.4V (BV) breakd.wn voltage. Based.on these parameter obtained. the power MOS d.vice mad. can actually withstand.high voltage with measured.breakd.wn voltage at 8.5V. However, regard.to laterally d.ffuse metal oxid. semicond.ctor d.vice, we will explore the epitaxial layer thickness effect on the d.vice's ability to withstand.voltage. When epitaxial layer thickness is increased. the ability to withstand.voltage been enhanced.up to 50%. By contrast, the ability to withstand.voltage been red.ced.up to 44% when epitaxial layer thickness is d.creased. © 2012 IEEE.

Build.ng maps of unknown environments is a critical factor for autonomous navigation and.homing, and.this problem is especially challenging in large-scale environments. Recently, sensor fusion systems such as combinations of cameras and.laser sensors have become popular in the effort to ensure a general level of performance in this task. In this paper, we present a new homing method.in a large-scale environment using a laser-camera fusion system. Instead.of fusing d.ta to form a single map build.r, we ad.ptively select sensor d.ta to hand.e environments which contain ambiguity. For autonomous homing, we propose a new mapping strategy for build.ng a hybrid.map and.a return strategy for selecting the next target waypoints efficiently. The experimental results d.monstrate that the proposed.algorithm enables the autonomous homing of a robot in a large-scale ind.or environments in real time.

In this stud., a novel positioning mod.l of a d.uble-CCd.cameras calibration system, with an Alternate-Eight-Matrix (AEM) Look-Up-Table (LUT), was proposed. Two CCd.cameras were fixed.on both sid.s of a large scale screen to red.em Field.Of View (FOV) problems. The first to the fourth AEMLUT were used.to compute the correspond.ng positions of intermed.ate blocks on the screen captured.by the right sid. camera. In these AEMLUT for the right sid. camera, the coord.nate mapping d.ta of the target in a specific space were stored.in two matrixes, while the gray level threshold.values of d.fferent position were stored.in the others. Similarly, the fifth to the eighth AEMLUT were used.to compute the correspond.ng positions of intermed.ate blocks on the screen captured.by the left sid. camera. Experimental results showed.that the problems of d.ad.angles and.non-uniform light field. were solved. In ad.ition, rapid.and.precision positioning results can be obtained.by the proposed.method.

Journal of ph.sics: Conference Series 2011年第1期266卷

作者： Y H Chen H C Chang C C Lai I N Chang Ph. D. Program in Electrical and Communications Engineering Feng-Chia University Taichung 40724 Taiwan ROC Department of Automatic Control Engineering Feng-Chia University Taichung 40724 Taiwan ROC

A fully integrated.wireless ind.ctance-capacitance (LC) coupling microsensor was d.signed.and.fabricated.by MEMS technology. The sensing loop was formed.by connecting a d.formable parallel-plated.capacitor and.a planar spiral ind.ctor with a Ni(80)Fe(20) core. Polyimid. and.PMMA were used.to isolate and.package the d.vices. Typical d.mension of the sensors was 5 × 5 mm2 × 0.77 mm. d.fferent electroplated.ind.ctive coils (30, 40, and.60 turns) were fabricated.to connect with a 4 × 4 mm2 plate capacitor in series. The LC sensing mod.le for measuring liquid.level ind.ced.frequency responses was setup. Experimental results show that frequency response d.creased.as liquid.level increased.and.sensitivity is about 7.01 kHz/cm with d.viation less than 2%. d.veloped.planar spiral ind.ctor with high permeability magnetic core can provid. a wid. range of frequency variation in LC sensing applications.
