It has become fundamental to wearable health monitoring devices. The human vital signs, such as heart rate (HR), Oxygen saturation (SpO2) and respiration rate, can be clearly extracted from the PPG signal. In this paper, we applied reflectance pulse measurement method on an organic optoelectronic device to measure the PPG signal. We fabricated a monolithic device, a red (625nm) organic light-emitting diode (OLED) and an organic photodiode (OPD) sensitive at the aforementioned wavelength. The external quantum efficiency (EQE) of the OLED and the OPD were 7% and 47%, respectively. In this work, we utilized a Bluetooth Low Energy (BLE) for sending the measured PPG signal to the central side, desktop computer. The data traffic of the BLE module was 2 kbps at the minimum connection interval 7.5 ms. The reflectance method showed very good results of (1.5) percent error of the heart rate compared to the commercially reference we obtained.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133810360","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}

It is important to determine different parameters in the diabetic foot that can be used as indicators that help to prevent the development of this complication. In this work, we are presenting a system that allows the measurement of parameters that will be used for the early detection of diabetic foot composed of two main devices for measuring the electrical impedance and the temperature of the foot. These measurements were made in areas of the foot most prone to ulceration in people with diabetes. The two devices are connected to a concentrator and distributor of information system whose purpose is to obtain and store the data of other sub-systems for measuring other physical parameters, which permits to expand gradually the variables to analyze. Preliminary results indicate that there are significant differences in the measurements of electrical impedance in the interval of 5 to 22 kHz, when we compare diabetic people vs. non-diabetics. Another significant difference was found in the temperature measurement in the zone of the foot corresponding to the first metatarsal. These results could indicate that the temperature and the electrical impedance of the foot could be used as a tool for pre-diagnosis diabetic foot.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123655672","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}

At present, the optics of the system are customized for carbon dioxide (CO2), however the design is intended to be scalable to other pollutant and green-house gases produced by such engines. For measurement of per-beam path concentration integrals (PCIs) of a gas species, tunable diode absorption spectroscopy (TDLAS) and wavelength modulation spectroscopy (WMS) are used. These techniques have been demonstrated, however this paper reports progress on the significant embedded, highly-distributed data acquisition (DAQ) systems that are integral to the instrument. Much of the mechanics and optics are finalized, tested and published, however we will briefly discuss these. The DAQ is parallel due to the high gas-speeds (100–200 m/s), and hierarchical to allow a multi-node system capable of both in-situ signal processing and scalability to higher numbers of projection angles, beams and exhaust gasses. We briefly describe the hardware and gate-level firmware, highlighting that TDLAS/WMS signals are demodulated using dual-harmonic digital lock-in amplifiers (DLIAs) implemented per-channel. Each distributed node can digitize up to sixteen analog channels at 10 to 40 MS/s (14-bit) with an analog bandwidth of 10 Hz to 3 MHz, which is tailored for TDLAS. The digital system, which uses regular interrupts to obtain and transmit data, is suitable for 20 frame/sec tomography, although the spectroscopy and image reconstruction is necessarily off-line. This work demonstrates progress towards a scalable multi-channel DAQ suitable for the harsh environment within jet-engine testing facilities.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122749035","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}

Notable among these devices are autonomous wheelchairs, which are capable of navigating to given destinations while avoiding obstacles. However, the method of destination selection and navigation in unmapped indoor environments remains a challenge for these autonomous wheelchairs. In this work, a novel approach to selecting a destination for an autonomous wheelchair in an unmapped indoor environment using a camera, ranging LIDAR, and computer vision is presented. The system scans the environment at startup and compiles a list of possible destinations for a user to easily make an selection. The proposed system was tested in a simulated shopping mall environment where destinations included various stores. The computer vision system was tested with images of store-fronts at various distances and angles. Ten trials were conducted to test the navigation system with destinations at close-range, mid-range, and long-range. The system successfully navigated to the destination in 100% of the trials for close-range destinations and 90% of the trials for mid-range and long-range destinations. Based on these results, we conclude the proposed design is a promising means of destination selection for autonomous wheelchairs in unmapped indoor environments for individuals with severe disabilities.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117116550","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 more detail, the paper presents the uncertainty evaluation of a simplified load flow algorithm, which is based on the load power measurements at each secondary substation and one voltage measurement at the slack bus (i.e. the voltage at the MV bus bars of the primary substation). To reduce the costs of the monitoring system, the load flow algorithm makes use of LV load power measurements for all the substations except those of MV users, where MV transducers are usually already installed. The uncertainties on the algorithm input quantities (load powers and slack bus voltage) are calculated, considering the actual values of the loads power factors and currents and the accuracy specifications of the measurement instruments installed in the distribution network. Starting from the input quantities uncertainties, the power flows uncertainties are obtained applying the Monte Carlo analysis. The analysis is carried out on a real test system, i.e. the distribution network of Favignana Island. The compatibility is also shown between the algorithm power flow estimations and the power measurements.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121231624","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}

MWA is proposed as a treatment for breast cancer in initial or intermediate stages and involves the application of an electromagnetic field that generates a temperature increase in the cancerous tissue. For the design of the applicator antenna, different parametric sweeps were performed, with the purpose of improving its efficiency and reducing the SWR when the antenna is inserted into the tissue. Ideally, when the impedance coupling is perfect, the ratio between the incident or sent power and the reflected power would result in an SWR of 1:1. This means that all the incident power provided by the source is transmitted without losses to the load; therefore, there is no reflected power. The SWR is a measure that determines the level coupling of an antenna with the medium, between closer to 1 the antenna will be more efficient at the moment of transmitting the power to the tissue. A SWR of 1.1 was obtained from the antenna, which indicates that the antenna has a good coupling in the tissue to be treated. The model was simulated by using the Finite Element Method (FEM).","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121312071","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}
