This paper describes the development of virtual medical instruments as a flexible, safe, and scalable learning option that can provide real-time feedback for the resident and increase entrustability by the attending surgeon when the resident is in the operating room. In orthopedic surgery, total hip arthroplasty (THA) is reproducible and hence was chosen as the simulated training surgery. The virtual medical instruments developed for this research is set in a fully immersive 3D virtual environment that can allow for innovative ways to train students and provide a new way of experiential education. With the goal of making the training anatomically accurate, users can interact with the virtual operating environment in real-time to ensure proper instrument usage. The virtual procedure also provides realistic visualization of the surrounding operating room and anatomical environment around the surgery site, marking important landmarks to the surgeon to enable effective surgical training.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"44 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":"125157532","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 aim is to make the car highly automated. Thus, the demands on such ADAS or systems that are necessary for these ADAS are increasing analogously. The systems must be fault-tolerant and reliable. For this purpose, it is necessary that the individual systems themselves are continuously checked by monitors. But even such monitors can fail. It is therefore important that the monitors are also constantly checked. For example, faults can be intentionally injected into the system in order to observe the subsequent reaction of the monitor. For highly automated vehicles, it is obviously necessary to apply more and more sophisticated fault injection methods in order to detect faults in the system at an early stage and accordingly replace components before a possible failure. In case, preventive maintenance is no longer possible, the system should be able to provide at least part of its functionality - fail-operational - or be shut down completely - fail-safe. In this publication, an architecture with corresponding fault injection modules for MEMS-based LiDAR systems is proposed. The architecture has been implemented in an FPGA prototyping platform to demonstrate its feasibility and evaluate its performance.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"4 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":"115351463","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 area, Visible Light Communications (VLC) are on the way of making the transition from an emerging technology to a confirmed technology. In the upper mentioned context, this paper presents the results of an experimental demonstration of Infrastructure-to- Vehicle VLC link in outdoor conditions. For these field tests, a commercial traffic light has been used as a VLC emitter, whereas a photodiode-based VLC receiver has been used to transform the optical beam into an electrical signal. The experimental results demonstrate a communication range of up to 188 meters at a BER of 10–3, with BERs as low as 10–6 for distances below 170 meters. As far as we know, this is the longest I2V VLC link based on standard road side unit equipment reported. Thus, the 188 m I2V VLC link delivered in this paper provides extremely encouraging evidence concerning the use of the VLC technology in automotive applications.","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":"116523872","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}

Gamma camera provide an image of the target organ, with high spatial resolution and sensitivity; gamma cameras use collimators. This paper presents a simple and customizable collimator to be used in radionuclide imaging for preclinical studies, using additive manufacturing (AM) techniques. A numerical analysis, based on GATE Monte Carlo toolkit (vGate 8.2), has been conducted to simulate different configurations of an already working collimator used as reference. In addition to the standard collimator geometry with alternatives materials, we also propose a new concept of collimator to be easily 3D printed, using different 3D printing technologies. We have simulated collimators with square apertures of 1.5 mm and septa of 0.4 mm of thickness, source was Tc99m. The materials simulated were standard tungsten, a PLA doped with tungsten (Rapid 3D Shield Tungsten Filament - Virtual Foundry), a classical PLA filament and P A2200 for the new concept. The results show a similar behavior for what concern the spatial resolution, while for the sensitivity a reduction of about 45% of entries is reported. This is due mainly since the extruded pixel, made of PLA or PA2200, have higher density $(approx$ 1.24 g/cm^3 for PLA and $approx 0,95$ g/cm^3 for PA2200) with respect to air $(approx$ 0,0012 g/cm^J). Further studies are necessary to explore optimization of the used design to reduce the impact of material density.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"22 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":"130575169","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}

Out of available soil-moisture sensors, the dual-probe heat-pulse (DPHP) sensor is the potential candidate due to its optimum price and better accuracy. A DPHP sensor has the heater probe kept at a distance from the temperature sensor probe. Heater probe consist of nichrome wire as the heating element, which is embedded in the stainless-steel tube. In this paper, we examine the acceptable tolerance in the heater resistance across 25 DPHP sensors, for the accurate soil moisture measurement. For this purpose, we used in-house developed 25 DPHP sensors where heater resistance is about 56 $Omega$ with $pm$ 5% tolerance. Under laboratory condition, we observed that difference in the measured volumetric water content (VWC) is within $pm$ 3 % (VWC) when compared with standard gravimetric method. For the field measurements, we developed the automated-self sustained system and deployed 3 systems on the rooftop of the building. Under field conditions, we observed that difference in the measured VWC from the 3 systems is within $pm$ 3 % (VWC) when benchmarked with standard gravimetric method.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"36 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":"127885611","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 work, we propose a low power multi-sensors hardware-software co-design for extremely long shelf life, and a long operating lifecycle. The designed device is based on a Bluetooth Low Energy (BLE) system on chip (SoC) to exchange data with a gateway. NFC has been chosen to wake up the device without adding any additional power consumption. The system on a chip includes an ARM Cortex-M4F core to further process the information achieving low latency and high energy efficiency. The device hosts a temperature and humidity sensor used to monitor the storage conditions, and an accelerometer is used for condition and activity monitoring. This paper provides a proof-of-concept approach to continuously assess the usage of a power tool and detect potential mis-usages, e.g., drops. The architecture, thought to be flexible, can host both traditional signal processing and novel tiny machine learning workloads, offering a future-proof platform for several application scenarios. Experimental results highlight the advanced processing capabilities at low power consumption enabling a long lifetime of up to 4 years with a small coin battery.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"69 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":"126395400","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}
