The CMUT based on MEMS technology with its unique advantages of good matching with air, has become the favorite transducer of the new generation of ultrasound imaging system. In this paper, a 16-element CMUT array for air-coupled application is designed and fabricated. The comprehensive tests in lab are provided to show the performance of the CMUT array. The resonance consistency and the selection of the driving parameters (i.e. the DC bias voltage and AC excitation amplitude) have been tested and analyzed, which can be used to optimize the driving strategy of the CMUT for better transmission and reception. A two-dimension air-coupled imaging test is performed with the CMUT array. The results show that it is feasible to image the contour and position of the object with the air-coupled CMUT array proposed in this paper. It also provides a possibility for the application of CMUT in relevant fields including human-computer interaction and gesture recognition.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117153368","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}

The multi-camera stereo vision, which is composed of more than two cameras, provides more image information, stronger interference capability and higher 3D reconstruction accuracy than binocular vision, has been widely used. The imaging quality, camera calibration accuracy and vision system structure parameters of different cameras may be different. However, in the traditional multicamera stereo vision, the contribution of each camera to the reconstruction results is the same, which may lead the reduction of the reconstruction accuracy. In this paper, multi-camera stereo vision based on weights is proposed to reduce the impact of cameras with large errors, eventually, the measurement accuracy is improved. The error characteristics are analyzed comprehensively, and the error model is established to calculate weights, then the weighted least square method is used for 3D reconstruction. The feasibility of the proposed method is verified by the trinocular vision 3D reconstruction experiment. Compared with the traditional 3D reconstruction method based on least square method, the accuracy is improved by about 3%.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124688156","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}

While the total amount of captured fish production has remained almost constant in the last 30 years (around 90 millions tonnes according to the Food and Agriculture Organization (FAO) of the United States), in the same span of time the quantity of bred fish has increased tenfold, almost reaching the quantity of the captured one. What was once little more than a hand-crafted production, is now an actual industrial sector, employing around 60 million workers all around the world. Like all industrial sectors, aquaculture can considerably benefit by the introduction of Internet of Things (IoT) technologies, thus adopting them within the context of Industry 4.0 to optimize fish farming processes. In this context, this paper proposes a real-time monitoring infrastructure based on the use of Fixed Nodes and Mobile Sinks for the remote, real-time control of offshore sea farms. The proposed architecture exploits a LoRaWAN network infrastructure for data transmission: different configurations are tested on the field, proving the reliability of the communication channel in a worst case scenario up to a 8.33 km offshore distance. A complete real-time monitoring system is presented, allowing to measure in real time several parameters about the quality of water in the fish cages as well as their maintenance status.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"146 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125857109","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}

In the experimental scenario the UWB transmitter and receiver units were placed on the front and back sides of the thoracic wall. The measurement principle is based on the fact that periodic movements of lung affect the communication channel properties that can be measured. We measured the energy attenuation variations on the receiver side caused by tissue movements from which we extracted the information about the respiration rate. For testing purpose, a custom developed UWB platform suitable for on-body placement was used, with an integrated inertial motion unit (IMU) sensor. UWB and IMU signals were combined by means of a data fusion algorithm. Data fusion algorithms based on Extended Kalman filtering (EKF) and Naïve Bayes inference show better estimation performance than an estimation from individual signal sources. The obtained error rate of RR estimation by means of the proposed data fusion method is lower than 0.2 respiration per minute (rpm) in comparison to the reference respiration system. Our results show that the proposed method of UWB and IMU sensor fusion is a promising candidate for reliable RR monitoring by compact wearable units under relatively non-stationary body movement conditions.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125942035","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}
