In the past, the authors have invented a device called “bubble injection knife”. In this device, high-speed micro-bubbles are ejected piercing through a reagent interface by discharging from a Cu wire, transporting a thin reagent membrane formed on the surface of the bubble due to its adsorption force. In addition, it is known that micro-bubbles contract and collapse. In this study, the authors designed a device using the properties of micro-bubbles and the bubble injection knife, which purpose is to reduce reagent consumption and enable uniform mixing in chemical analysis. This device is a micro-chip which is designed to produce micro-bubbles by electric discharge from a “bubble kife” embedded in the micro-channel and make them penetrate through reagent laminar flows in order to form reagent layers on the bubble's surface. Moreover, the mixing of these layers using the contraction force of the bubbles is expected. In the experiments that were conducted, micro-bubbles were produced in the micro-channel from the embedded bubble knife. This technology is expected to improve chemical analysis methods to overcome ununiformed concentration within the mixed solution, and also it is expected to contribute to the bio-medical reagent injection with control of reaction time.","PeriodicalId":165544,"journal":{"name":"2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122504490","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}

Previous research shows that satisfactory accuracy of gaze estimation can be achieved in constrained settings. However, most of the existing methods can not deal with large head movement (LHM) that frequently happens when interacting with children with ASD scenarios. We propose a gaze estimation method aiming at dealing with large head movement and achieving real time performance. An intervention table equipped with multiple sensors is designed to capture images with LHM. Firstly, reliable facial features and head poses are tracked using supervised decent method. Secondly, a convolution based integer-differential eye localization approach is used to locate the eye center efficiently and accurately. Thirdly, a rotation invariant gaze estimation model is built based on the located facial features, eye center, head pose and the depth data captured from Kinect. Finally, a multi-sensor fusion strategy is proposed to adaptively select the optimal camera to estimate the gaze as well as to fuse the depth information of the Kinect with the web camera. Experimental results showed that the gaze estimation method can achieve acceptable accuracy even in LHM situation and could potentially be applied in therapy for children with ASD.","PeriodicalId":165544,"journal":{"name":"2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121652453","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}

This is usually performed through joint position control, where each orthosis joint follows a specific angle trajectory as a reference. The most commonly used approach for generating this required references is to create a set of average joint trajectories from a gait database, and use them as a set of default references. Although recent approaches shown improvement, the influence of a user oriented gait trajectory to the orthosis general performance is still unknown. Nevertheless, due to the complexity of human gait system and individual body reaction when wearing an active lower limb orthosis, the efficacy and performance of such devices are still in current analysis. Taking the metabolic effort realized during gait and the electric power used by the motors in consideration, this work presents a performance comparison between different types of trajectories followed by the orthosis. The metabolic effort realized by the user will be obtained through the measurement of the heart beat rate. The experiments were realized in Ortholeg orthosis with a healthy subject. The main contribution of this work is to provide information regarding the influence of different gait types an active lower limb orthosis performance, allowing a better gait trajectory planning that can be used for daily walk or for rehabilitations programs.","PeriodicalId":165544,"journal":{"name":"2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134206966","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}
