As a result two innovative methods of monitoring respiratory parameters and cough incidents for patients with respiratory failure, caused by asthma or covid-19. The first sensor was made of the piezoelectric membrane, and the second uses conductive elastic rubber that changes its resistance when stretched. Both sensors were placed on the patient’s chest using a specially designed for this purpose belt.Simultaneous biomedical signals were recorded in laboratory conditions for various measurement methods, which showed chest movement during breathing in healthy people with the simulation of difficult measurement conditions, such as shallow and rapid breathing, slow deep breathing combined with apnea, and in the presence of motor disturbances. The obtained results for both measurement methods allow confirming a satisfactory immunity to movement disturbances and correct detection in extreme measurement conditions such as fast and shallow breathing and apnea while the piezoelectric method, enables recording with better resolution in conditions of fast and shallow breathing. Both piezoelectric and resistive methods are correct for creating sensors that monitor basic patients’ respiratory parameters. Their additional advantage is the simplicity and low cost of production which may be important in examining geriatric patients and neonates however piezoelectric is cheaper and less burdensome during the long-term recording of respiratory parameters","PeriodicalId":375541,"journal":{"name":"2021 28th International Conference on Mixed Design of Integrated Circuits and System","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128842887","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 general, we should argue from a different perspective: we don’t want to show the latest and greatest Machine Learing (ML) results. The intention of the paper is to show how state of the art products use ML for safety critical applications. It is the goal to avoid the deployment of an airbag. Today, saftey applications depend on various detection algorithms and sensor systems. The challenge for these kind of decision problems depend on crucial constraints named decision time and sensor signals which are complicated to distinguish. The system has to decide whether to fire or not to fire an airbag within a few milliseconds. We use a (Multiclass) Support Vector Machine to account for an improved classification with the given constraints. Various multiclass classification methods are rated and the two methods One-Versus-Rest and One-Versus-One are benchmarked in terms of quantities as test error, training time, memory consumption and misclassified crashes. All methods are applied to real measurement data of car crashes for the type of full frontal crashes in various conditions. We will show that One-Versus-One performs best. The method is able to classify car crash situations and improve the detection possibility. This allows for active and passive occupant safety components in the automotive area.","PeriodicalId":375541,"journal":{"name":"2021 28th International Conference on Mixed Design of Integrated Circuits and System","volume":"1086 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133344026","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}

Efficient algorithms enable machine protection, contributing to future steady-state operation in nuclear fusion devices. The paper evaluates the applicability of the newest low-power NVIDIA Jetson Xavier NX platform for fusion diagnostics. This embedded NVIDIA Tegra System-on-a-Chip (SoC) integrates a Graphics Processing Unit (GPU) and Central Processing Unit (CPU) on a single chip. General-Purpose computing on Graphics Processing Units (GPGPU) provides high parallelism that is advantageous in image-based calculations. The hardware differences in comparison to the previous NVIDIA Jetson TX2 based on Pascal architecture, including innovations introduced in the Volta architecture for NVIDIA Tegra, are signified. The evaluation is performed on the Wendelstein 7-X (W7-X) stellarator experimental data. Implemented algorithms detect and analyse thermal events in real-time utilising the embedded GPU. Investigated thermal events are strike-lines, overload hotspots, reflections and surface layers. Their detection allows the automated real-time risk evaluation incorporated in the feedback plasma control and interlock systems in the W7-X. The speedup resulting from the upgrade to the Xavier NX platform is presented in the paper, along with techniques pertaining to key hardware differences and programming aspects specific to the NVIDIA Tegra facilitating real-time computing on the low-power embedded device.","PeriodicalId":375541,"journal":{"name":"2021 28th International Conference on Mixed Design of Integrated Circuits and System","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134116497","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}
