The BBA is composed of three variable gain amplifier stages and two complex biquad stages. The gain and bandwidth tuning capabilities are needed to maximize the receiver dynamic range and support the variable data rates. The center frequency and Q-factor tunings are realized for optimum filtering and amplification performances. The gain tuning range is from −15 dB to +52 dB and the bandwidth tuning range is from 250 kHz to 2.9 MHz. The image rejection ratios are found to be 39 and 42 dB at the maximum bandwidth of 2.9 MHz and the minimum bandwidth of 250 kHz conditions, respectively. The layout size is 0.42 mm2 including the I/Q paths, while dissipating 1.5 mA from a 1-V supply.","PeriodicalId":127156,"journal":{"name":"2018 International SoC Design Conference (ISOCC)","volume":"35 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113976968","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}

Existing histogram-based methods find the cluster centers by analyzing the distribution of the 3D color histogram values. It is difficult to consider the overall characteristics of an image by analyzing the distribution of the 3D color histogram values. Thus, Existing histogram-based methods have difficulty to finding the optimal cluster centers. To overcome this drawback, the proposed method uses both 3D color histogram and human visual attention analysis to find the optimal cluster centers by considering the overall characteristic of the image. Compared with the benchmark methods, the experimental results show that the proposed method improved the segmentation accuracy.","PeriodicalId":127156,"journal":{"name":"2018 International SoC Design Conference (ISOCC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121070937","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 system employs a motion artifact extraction method based on a triple-axis accelerometer attached to each electrode independently to remove motion artifact from ECG signals with high performance. Recursive Least Square (RLS) and Least Mean Square (LMS) algorithms remove extracted noise from the source signals, thereby obtaining a mean square error (MSE) of 0.0166 when using RLS and 0.0160 when using LMS. This means that the performance improved respectively by approximately 5.1% and 8.6% compared to that of the recently developed ECG monitoring system.","PeriodicalId":127156,"journal":{"name":"2018 International SoC Design Conference (ISOCC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123898332","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}

If it is not possible, UAV return by performing the proposed local path planning algorithm.
