Cellular thermodynamics (intracellular thermal components of absorption) has recently been intensively investigated because of its implication in different molecular mechanisms. A Thermoelectric sensor can thus provide information about changes happening inside a cell. The work focuses on the design and fabrication of a dual pyroelectric sensor for the thermal characterization of cultured cells. The device is based on the use of two pyroelectric elements stimulated by an Infrared source. It is inherently compact and designed for compensating for the effect of the culture media in which the cells are maintained. Experimental results on the ARPE-19 cell line at different concentrations evidenced a linear dependence of the dual-sensor's output. Moreover, with respect to its single-element counterpart, the effect of common-mode signals (such as that of culture media) is drastically reduced. The dual sensor is thus a promising characterization tool for rapid lab-based applications.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122231362","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}

Although, in some instances GPS it is not always the most preferred method especially in places where the coverage is lacking, and where privacy is a concern. In the last few years, alternative technologies to GPS systems have been developed and are available not only to enterprises but to consumers as well. This paper presents an idea on how a convoy of vehicles can establish and maintain a leader-follower connection between themselves by utilizing Computer Vision Technology and Received Signal Strength Indicator (RSSI) via wireless low-power networks. The proposed system is to consists of three vehicles, a leader vehicle being controlled by an operator via Bluetooth, and two follower vehicles equipped with DFRobots' Romero V2, BLE Boards, and XBee modules for RSSI navigation. The computer vision system will utilize ZED Stereo Camera for image processing and the Robotic Operating System (ROS). The system will be independent of GPS allowing the operation in environments where GPS is unavailable or unpermitted. The proposed system can be utilized in surveillance missions, rescue missions, and it can serve as a backup to other leader-follower systems.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124735731","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 can result in alarm fatigue which increases the risk that alarms of clinical significance are overlooked and may lead to an increased response time. It is therefore of interest to minimize false alarms in the NICU to reduce alarm fatigue. Previous alarm classification systems rely on physiologic data and waveforms. In this study, we explore the use of a pressure sensitive mat (PSM), which is an unobtrusive and non-contact secondary sensor system that captures motion-related data. We use a dataset of 136 manually annotated alarm events for 10 neonatal subjects to train a machine learning model for the detection of false alarms. Results show that a combination of physiologic and PSM features has the best performance, which achieves a 0.87 macro-averaged F1 score, compared to the model that solely relies on physiologic data which only achieves a 0.73 macro-averaged F1 score. We also show that the use of PSM data improves the model's ability to generalize to unseen patients using a leave-one-subject-out test protocol. This study demonstrates that the PSM provides complementary and useful information for Improving the discrimination of true and false alarms.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124576841","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 this study, a low-frequency magnetic localization method for capsule endoscopes with an integrated active coil is proposed. The spatial constraint, the limited battery capacity and the ferromagnetic battery shell of commercial capsules were considered. The generated magnetic flux density was evaluated depending on the distance to the coil and the maximal detectable range was determined. Twelve sensors were arranged in rings and by comparing the measured magnetic flux density with the analytic dipole model, the position and orientation of the coil were reconstructed. The results revealed that the ferromagnetic shell increases the magnetic moment of the coil by approximately a factor of 2.4. Moreover, the mean position and orientation errors were 0.5 mm and 0.3°. Furthermore, by using only the three closest sensors to the coil, a similar localization performance was achieved. Therefore, it was concluded that it is a feasible approach to choose the sensors, which measure the strongest signal to address the problem of the maximal detectable range of magnetic sensors. Moreover, by considering the limited battery capacity, the localization with the proposed coil must be conducted in short time intervals instead of continuously.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114250566","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}
