However, the existing micropump is separated into flow part and pump part. The miniaturization of device is difficult, since the designing of flow part is too complex. Therefore, we developed tube type micropump which is the integration of flow part and pump part. This micropump consists of several ring type PZTs in equal intervals on the hollow tube. By adding AC voltage to the PZTs, the PZTs vibrates, and the vibration of PZT is transmitted to the liquid in the hollow tube. Therefore, tube type micropump can transmit liquid. However, flow rate of the tube type micropump is extremely few. Thus, it is necessary to improve fluid performance by increasing deformation amount of PZT actuators. The increasing deformation amount of PZT by adding rectangle trenches is confirmed under FEM analysis. However, according to Static piezoelectric analysis, the stress concentration occurs at the trench part. Therefore, we search for the optimum trench shape which can scatter the stresses while maintain the deformation amount of PZT by static piezoelectric analysis. We focused on (a) existing rectangle trench, (b) trapezoid trench, (c) curvature trench and they were analyzed. As a result, the reduction of equivalent stress is confirmed by changing trench shape from rectangle to other trench shape. However, deformation amount of PZT was decreased by changing trench shape from rectangle to other trench shape. Therefore, it is necessary to search the optimum trench conditions.

The traffic signal control system with video camera sensor is implemented in embedded systems using BeagleBoard-xM.

The ability of kalman filter in predicting the next position of the object is a very important feature for multi-object tracking. The number of counted vehicles in each lane at the intersection then will be processed using Fuzzy Logic to determine optimal cycle time and split time.","PeriodicalId":286457,"journal":{"name":"2011 International Symposium on Micro-NanoMechatronics and Human Science","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126204135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nano manipulations of biological samples using the haptic control system of the AFM are demonstrated. Furthermore, we introduce a real time nanomanipulation system based on a high-speed atomic force microscopy (HS-AFM) . Even under surface manipulation using the AFM probe, the topographical image of the manipulated surface is periodically updated by HS-AFM.

Most of biped walking control methods based on point-contact assume that foot-contact is completely inelastic collision and it occurs for a moment. Thus, it is difficult to realize biped walking when the assumptions are not satisfied. In order to solve this problem, we propose a three-dimensional biped walking control using a double support phase based on Passive Dynamic Autonomous Control (PDAC) that is one of point-contact methods. By use of the double support phase, the robot dynamics converges to stable orbit even if a disturbance happens at a foot-contact. Also, this paper introduces an adaptation control method of the PDAC constants that facilitates stabilization. Finally, the proposed biped walking algorithm is verified by numerical simulation.","PeriodicalId":286457,"journal":{"name":"2011 International Symposium on Micro-NanoMechatronics and Human Science","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128063954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extracting features out of poor quality prints is the most challenging problem faced in this area. In this paper, the texture feature based approach for fingerprint recognition using Discrete Wavelet Transform (DWT) is developed to identify the low quality fingerprint from inked-printed images on paper. The fingerprint image from paper is very poor quality image and sometimes it is complex with fabric background. Firstly, a center point area of the fingerprint is detected and keeping the Core Point as center point, the image of size w x w is cropped. Gabor filtering is applied for fingerprint enhancement over the orientation image. Finally, the texture features are extracted by analyzing the fingerprint with Discrete Wavelet Transform (DWT) and Euclidean distance metric is used as similarity measure. The accuracy is improved up to 98.98%.","PeriodicalId":286457,"journal":{"name":"2011 International Symposium on Micro-NanoMechatronics and Human Science","volume":"269 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115312114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
