It utilizes the DFRobot Bettle BLE Arduino microcontroller as its main component for communication and control. By interfacing it with an LED and a buzzer, the system provides visual and auditory signals to assist in locating the target device. The search process can be initiated through an Android application, by which the system creates a Bluetooth connection between the microcontroller and the target device, permitting the exchange of signals for tracking purposes. When the device is within range, the LED indicator illuminates, and the buzzer produces audible alerts, guiding the user to the device's location. The application also provides an estimated distance of the object using Bluetooth signal strength. The project’s goal is to offer a practical and efficient solution for finding misplaced devices, leveraging the capabilities of Bluetooth technology and microcontroller-based control systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bluetooth%20finder" title="Bluetooth finder">Bluetooth finder</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20finder" title=" object finder"> object finder</a>, <a href="https://publications.waset.org/abstracts/search?q=Bluetooth%20tracking" title=" Bluetooth tracking"> Bluetooth tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=tracker" title=" tracker"> tracker</a> </p> <a href="https://publications.waset.org/abstracts/179777/design-and-implementation-of-a-bluetooth-based-misplaced-object-finder-using-dfrobot-arduino-interfaced-with-led-and-buzzer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179777.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">73</span> An AI Based Smart Conference Calling System Using Bluetooth Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankita%20Dixit">Ankita Dixit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A conference call using a mobile refers to a telephonic call in which several people talks to each other simultaneously. This is one of the most eminent features nowadays. This concept is already existing using LTE technology for mobile phones supporting SIM cards. Hence, currently, a conference call is possible only with the support of a SIM card, i.e., a Mobile operator. Bluetooth is a short-range wireless technology that is used for exchanging data between devices placed over short distances (up to 240 meters). This is a booming technology that is easily and freely available and has no dependency on network operators. Our study work proposes a smart system to enable conference calls with more than two mobile users without SIM support to communicate with each other simultaneously. The AI-based proposed solution will be self–governed, self-learned and will be intelligent enough to smartly switch between all callers connected via Bluetooth in a conference call. This proposed solution system will greatly increase the potential of using Bluetooth technology from a wider applicability perspective of conference calls, which is currently only possible over LTE mobiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conference%20call" title="conference call">conference call</a>, <a href="https://publications.waset.org/abstracts/search?q=bluetooth" title=" bluetooth"> bluetooth</a>, <a href="https://publications.waset.org/abstracts/search?q=AI" title=" AI"> AI</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20hopping" title=" frequency hopping"> frequency hopping</a>, <a href="https://publications.waset.org/abstracts/search?q=piconet" title=" piconet"> piconet</a>, <a href="https://publications.waset.org/abstracts/search?q=scatter%20net" title=" scatter net"> scatter net</a> </p> <a href="https://publications.waset.org/abstracts/168925/an-ai-based-smart-conference-calling-system-using-bluetooth-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168925.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">72</span> Design and Implementation of Bluetooth Controlled Autonomous Vehicle </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amanuel%20Berhanu%20Kesamo">Amanuel Berhanu Kesamo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents both circuit simulation and hardware implementation of a robot vehicle that can be either controlled manually via Bluetooth with video streaming or navigate autonomously to a target point by avoiding obstacles.

Since Bluetooth cannot utilize techniques like Time Difference of Arrival (TDOA) and Time of Arrival (TOA), it uses received signal strength indicator (RSSI) to measure Receive Signal Strength (RSS). The measurements using RSSI can be improved significantly by improving the existing methodologies related to RSSI. Therefore, the current paper focuses on proposing an improved method using trilateration for localization of Bluetooth devices for visually impaired people. To validate the method, class 2 Bluetooth devices were used along with the development of a software. Experiments were then conducted to obtain surface plots that showed the signal interferences and other environmental effects. Finally, the results obtained show the surface plots for all Bluetooth modules used along with the strong and weak points depicted as per the color codes in red, yellow and blue. It was concluded that the suggested improved method of measuring RSS using trilateration helped to not only measure signal strength affectively but also highlighted how the signal strength can be influenced by atmospheric conditions such as noise, reflections, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bluetooth" title="Bluetooth">Bluetooth</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%2Foutdoor%20localization" title=" indoor/outdoor localization"> indoor/outdoor localization</a>, <a href="https://publications.waset.org/abstracts/search?q=received%20signal%20strength%20indicator" title=" received signal strength indicator"> received signal strength indicator</a>, <a href="https://publications.waset.org/abstracts/search?q=visually%20impaired" title=" visually impaired"> visually impaired</a> </p> <a href="https://publications.waset.org/abstracts/101797/received-signal-strength-indicator-based-localization-of-bluetooth-devices-using-trilateration-an-improved-method-for-the-visually-impaired-people" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101797.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">69</span> Pro-BluCRM: A Proactive Customer Relationship Management System Using Bluetooth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Alawairdhi">Mohammad Alawairdhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Customer Relationship Management (CRM) started gaining attention as late as the 1990s, and since then efforts are ongoing to define the domain’s precise specifications. There is yet no single agreed upon definition. However, a predominant majority perceives CRM as a mechanism for enhancing interaction with customers, thereby strengthening the relationship between a business and its clients. From the perspective of Information Technology (IT) companies, CRM systems can be viewed as facilitating software products or services to automate the marketing, selling and servicing functions of an organization. In this paper, we have proposed a Bluetooth enabled CRM system for small- and medium-scale organizations. In the proposed system, Bluetooth technology works as an automatic identification token in addition to its common use as a communication channel. The system comprises a server side accompanied by a user-interface support for both client and server sides. The system has been tested in two environments and users have expressed ease of use, convenience and understandability as major advantages of the proposed solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=customer%20relationship%20management" title="customer relationship management">customer relationship management</a>, <a href="https://publications.waset.org/abstracts/search?q=CRM" title=" CRM"> CRM</a>, <a href="https://publications.waset.org/abstracts/search?q=bluetooth" title=" bluetooth"> bluetooth</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20identification%20token" title=" automatic identification token"> automatic identification token</a> </p> <a href="https://publications.waset.org/abstracts/7113/pro-blucrm-a-proactive-customer-relationship-management-system-using-bluetooth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7113.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">68</span> Speed-Up Data Transmission by Using Bluetooth Module on Gas Sensor Node of Arduino Board</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiesik%20Kim">Hiesik Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=YongBeum%20Kim"> YongBeum Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Internet of Things (IoT) applications are widely serviced and spread worldwide.

The paper initially summarizes a number of clustering approaches and thereafter shows their performance for noise removal. In this context, clustering is used to recognize WiFi and Bluetooth MAC addresses that belong to passengers traveling by a public urban transit bus. The main objective is to build an intelligent system that automatically filters out MAC addresses that belong to persons located outside the bus for different routes in the city of Ottawa. The proposed intelligent system alleviates the need for defining restrictive thresholds that however reduces the accuracy as well as the range of applicability of the solution for different routes. This paper moreover discusses the performance benefits of the presented clustering approaches in terms of the accuracy, time and space complexity, and the ease of use. Note that results of clustering can further be used for the purpose of the origin-destination estimation of individual passengers, predicting the traffic load, and intelligent management of urban bus schedules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=WiFi-Bluetooth%20sensing" title="WiFi-Bluetooth sensing">WiFi-Bluetooth sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster%20analysis" title=" cluster analysis"> cluster analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20management" title=" traffic management"> traffic management</a> </p> <a href="https://publications.waset.org/abstracts/93601/an-intelligent-traffic-management-system-based-on-the-wifi-and-bluetooth-sensing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93601.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">241</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> Localization Mobile Beacon Using RSSI</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sallama%20Resen">Sallama Resen</a>, <a href="https://publications.waset.org/abstracts/search?q=Celal%20%C3%96zt%C3%BCrk"> Celal Öztürk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Distance estimation between tow nodes has wide scope of surveillance and tracking applications. This paper suggests a Bluetooth Low Energy (BLE) technology as a media for transceiver and receiver signal in small indoor areas. As an example, BLE communication technologies used in child safety domains. Local network is designed to detect child position in indoor school area consisting Mobile Beacons (MB), Access Points (AP) and Smart Phones (SP) where MBs stuck in children’s shoes as wearable sensors. This paper presents a technique that can detect mobile beacons’ position and help finding children’s location within dynamic environment. By means of bluetooth beacons that are attached to child’s shoes, the distance between the MB and teachers SP is estimated with an accuracy of less than one meter. From the simulation results, it is shown that high accuracy of position coordinates are achieved for multi-mobile beacons in different environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bluetooth%20low%20energy" title="bluetooth low energy">bluetooth low energy</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20safety" title=" child safety"> child safety</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20beacons" title=" mobile beacons"> mobile beacons</a>, <a href="https://publications.waset.org/abstracts/search?q=received%20signal%20strength" title=" received signal strength"> received signal strength</a> </p> <a href="https://publications.waset.org/abstracts/40610/localization-mobile-beacon-using-rssi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40610.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">346</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Bluetooth Piconet System for Child Care Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ching-Sung%20Wang">Ching-Sung Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Teng-Wei%20Wang"> Teng-Wei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhen-Ting%20Zheng"> Zhen-Ting Zheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study mainly concerns a safety device designed for child care. When children are out of sight or the caregivers cannot always pay attention to the situation, through the functions of this device, caregivers can immediately be informed to make sure that the children do not get lost or hurt, and thus, ensure their safety. Starting from this concept, a device is produced based on the relatively low-cost Bluetooth piconet system and a three-axis gyroscope sensor. This device can transmit data to a mobile phone app through Bluetooth, in order that the user can learn the situation at any time. By simply clipping the device in a pocket or on the waist, after switching on/starting the device, it will send data to the phone to detect the child’s fall and distance. Once the child is beyond the angle or distance set by the app, it will issue a warning to inform the phone owner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children%20care" title="children care">children care</a>, <a href="https://publications.waset.org/abstracts/search?q=piconet%20system" title=" piconet system"> piconet system</a>, <a href="https://publications.waset.org/abstracts/search?q=three-axis%20gyroscope" title=" three-axis gyroscope"> three-axis gyroscope</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20detection" title=" distance detection"> distance detection</a>, <a href="https://publications.waset.org/abstracts/search?q=falls%20detection" title=" falls detection"> falls detection</a> </p> <a href="https://publications.waset.org/abstracts/78252/bluetooth-piconet-system-for-child-care-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78252.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">597</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">64</span> Performance Analysis of Bluetooth Low Energy Mesh Routing Algorithm in Case of Disaster Prediction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmir%20Gogic">Asmir Gogic</a>, <a href="https://publications.waset.org/abstracts/search?q=Aljo%20Mujcic"> Aljo Mujcic</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Ibric"> Sandra Ibric</a>, <a href="https://publications.waset.org/abstracts/search?q=Nermin%20Suljanovic"> Nermin Suljanovic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ubiquity of natural disasters during last few decades have risen serious questions towards the prediction of such events and human safety. Every disaster regardless its proportion has a precursor which is manifested as a disruption of some environmental parameter such as temperature, humidity, pressure, vibrations and etc. In order to anticipate and monitor those changes, in this paper we propose an overall system for disaster prediction and monitoring, based on wireless sensor network (WSN). Furthermore, we introduce a modified and simplified WSN routing protocol built on the top of the trickle routing algorithm. Routing algorithm was deployed using the bluetooth low energy protocol in order to achieve low power consumption. Performance of the WSN network was analyzed using a real life system implementation. Estimates of the WSN parameters such as battery life time, network size and packet delay are determined. Based on the performance of the WSN network, proposed system can be utilized for disaster monitoring and prediction due to its low power profile and mesh routing feature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bluetooth%20low%20energy" title="bluetooth low energy">bluetooth low energy</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster%20prediction" title=" disaster prediction"> disaster prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20routing%20protocols" title=" mesh routing protocols"> mesh routing protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title=" wireless sensor networks"> wireless sensor networks</a> </p> <a href="https://publications.waset.org/abstracts/43894/performance-analysis-of-bluetooth-low-energy-mesh-routing-algorithm-in-case-of-disaster-prediction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43894.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">385</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Comparison of Power Consumption of WiFi Inbuilt Internet of Things Device with Bluetooth Low Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Darshana%20Thomas">Darshana Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Wilkie"> Edward Wilkie</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Irvine"> James Irvine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Internet of things (IoT) is currently a highly researched topic, especially within the context of the smart home. These are small sensors that are capable of gathering data and transmitting it to a server. The majority of smart home products use protocols such as ZigBee or Bluetooth Low Energy (BLE). As these small sensors are increasing in number, the need to implement these with much more capable and ubiquitous transmission technology is necessary. The high power consumption is the reason that holds these small sensors back from using other protocols such as the most ubiquitous form of communication, WiFi. Comparing the power consumption of existing transmission technologies to one with WiFi inbuilt, would provide a better understanding for choosing between these technologies. We have developed a small IoT device with WiFi capability and proven that it is much more efficient than the first protocol, 433 MHz. We extend our work in this paper and compare WiFi power consumption with the other most widely used protocol BLE. The experimental results in this paper would conclude whether the developed prototype is capable in terms of power consumption to replace the existing protocol BLE with WiFi. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bluetooth" title="bluetooth">bluetooth</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things%20%28IoT%29" title=" internet of things (IoT)"> internet of things (IoT)</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20consumption" title=" power consumption"> power consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=WiFi" title=" WiFi"> WiFi</a> </p> <a href="https://publications.waset.org/abstracts/54389/comparison-of-power-consumption-of-wifi-inbuilt-internet-of-things-device-with-bluetooth-low-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54389.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">267</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Application of Artificial Neural Network and Background Subtraction for Determining Body Mass Index (BMI) in Android Devices Using Bluetooth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neil%20Erick%20Q.%20Madariaga">Neil Erick Q.

It is based on the height and weight of the person. This study aims to compute for the BMI using an Android tablet by obtaining the height of the person by using a camera and measuring the weight of the person by using a weighing scale or load cell. The height of the person was estimated by applying background subtraction to the image captured and applying different processes such as getting the vanishing point and applying Artificial Neural Network. The weight was measured by using Wheatstone bridge load cell configuration and sending the value to the computer by using Gizduino microcontroller and Bluetooth technology after the amplification using AD620 instrumentation amplifier. The application will process the images and read the measured values and show the BMI of the person.

The appearance of Bluetooth Low Energy (BLE) has allowed a push to IoT in relation to smartphones. In this moment, a set of new applications related to several topics like entertainment and advertisement has begun to be developed but not much has been done till now to take advantage of the potential that these technologies can offer on many business areas and in everyday tasks. In the present work, the application of BLE technology and smartphones is proposed on some business areas related to the optimization of resource allocation in huge facilities like airports. An indoor location system has been developed through triangulation methods with the use of BLE beacons. The described system can be used to locate all employees inside the building in such a way that any task can be automatically assigned to a group of employees. It should be noted that this system cannot only be used to link needs with employees according to distances, but it also takes into account other factors like occupation level or category. In addition, it has been endowed with a security system to manage business and personnel sensitive data. The efficiency of communications is another essential characteristic that has been taken into account in this work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bluetooth%20low%20energy" title="bluetooth low energy">bluetooth low energy</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20location" title=" indoor location"> indoor location</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20assignment" title=" resource assignment"> resource assignment</a>, <a href="https://publications.waset.org/abstracts/search?q=smartphones" title=" smartphones"> smartphones</a> </p> <a href="https://publications.waset.org/abstracts/42890/optimizing-resource-allocation-and-indoor-location-using-bluetooth-low-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42890.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">394</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Explore the Effect of Telecare for the Elderly in Preventing and Delaying the Quality of Disability Care with Bluetooth Brainwave Equipment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jui-Chen%20Huang">Jui-Chen Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to explore the effects of telecare on preventing and delaying the quality of disability care in elderly people with portable comfort Bluetooth brainwave devices with remote healthcare functions. Through the teaching videos and remotely teaching the elderly, which had ever learned the care courses of the prevent and delay disability, these elderly did muscle strength training. Then this paper explores the effect of training with the data by SPSS 18.0 statistical software. The data is collected with pre-test, post-test and analyze data from the measure of the Bluetooth brain wave equipment including the pressure index, relaxation index, attention and fatigue index of the elderly. In this study, 30 elderly people who had taken preventive and delayed disability care courses were studied to explore the effect of their care quality improvement. The results showed that the pressure index, relaxation index, attention, and fatigue index of the elderly had statistically significant differences in two months. It can be seen that elderly people who have been treated to prevent and delay disability care courses can significantly improve their care quality if they continue to receive intensive training to prevent and delay disability through remote mode. This telecare is applied to the elderly program that has been used to prevent and delay disability care courses. It is worth continuing to promote, and it is recommended that follow-up studies be conducted in a longer-term manner to explore long-term benefits. It can solve the current insufficiency of long-term care resources, but the demand is urgent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=telecare" title="telecare">telecare</a>, <a href="https://publications.waset.org/abstracts/search?q=bluetooth%20brainwave%20equipment" title=" bluetooth brainwave equipment"> bluetooth brainwave equipment</a>, <a href="https://publications.waset.org/abstracts/search?q=prevention%20and%20delay%20of%20disability" title=" prevention and delay of disability"> prevention and delay of disability</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20elderly" title=" the elderly"> the elderly</a>, <a href="https://publications.waset.org/abstracts/search?q=care%20quality" title=" care quality"> care quality</a> </p> <a href="https://publications.waset.org/abstracts/100984/explore-the-effect-of-telecare-for-the-elderly-in-preventing-and-delaying-the-quality-of-disability-care-with-bluetooth-brainwave-equipment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100984.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Device to Alert and Fire Prevention through Temperature Monitoring and Gas Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D%C3%AAivisson%20Alves%20Anjos">Dêivisson Alves Anjos</a>, <a href="https://publications.waset.org/abstracts/search?q=Blenda%20Fonseca%20Aires%20Teles"> Blenda Fonseca Aires Teles</a>, <a href="https://publications.waset.org/abstracts/search?q=Queitiane%20Castro%20Costa"> Queitiane Castro Costa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fire is one of the biggest dangers for factories, warehouses, mills, among other places, causing unimaginable damage, because besides the material damage also directly affects the lives of workers who are likely to suffer death or very serious consequences.

The sensor and gateway nodes are designed using the ESP32 SoC with integrated Bluetooth Low Energy 4.2 and Wi-Fi. A development board, the Arducam IoTai ESP32, is used for prototyping, testing, and power measurements. Google’s Firebase is used as the cloud storage site for image data collected by the sensor. The sensor node captures images using the OV2640 2MP camera module and transmits the image data to the gateway via Bluetooth Low Energy. The gateway then uploads the collected images to Firebase via a known nearby Wi-Fi network connection. This image data can then be processed and analyzed by computer vision and machine learning pipelines to assess crop growth or other needs. The sensor node achieves a wireless transmission data throughput of 220kbps while consuming 150mA of current; the sensor sleeps at 162µA. The sensor node device lifetime is estimated to be 682 days on a 6600mAh LiPo battery while acquiring five images per day based on the development board power measurements. This network can be utilized by any application that requires high data rates, low power consumption, short-range communication, and large amounts of data to be transmitted at low-frequency intervals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bluetooth%20low%20energy" title="Bluetooth low energy">Bluetooth low energy</a>, <a href="https://publications.waset.org/abstracts/search?q=ESP32" title=" ESP32"> ESP32</a>, <a href="https://publications.waset.org/abstracts/search?q=firebase%20cloud" title=" firebase cloud"> firebase cloud</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20farming" title=" smart farming"> smart farming</a> </p> <a href="https://publications.waset.org/abstracts/128354/development-and-power-characterization-of-an-iot-network-for-agricultural-imaging-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128354.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Transferring Data from Glucometer to Mobile Device via Bluetooth with Arduino Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tolga%20Hayit">Tolga Hayit</a>, <a href="https://publications.waset.org/abstracts/search?q=Ucman%20Ergun"> Ucman Ergun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ugur%20Fidan"> Ugur Fidan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Being healthy is undoubtedly an indispensable necessity for human life. With technological improvements, in the literature, various health monitoring and imaging systems have been developed to satisfy your health needs. In this context, the work of monitoring and recording the data of individual health monitoring data via wireless technology is also being part of these studies. Nowadays, mobile devices which are located in almost every house and which become indispensable of our life and have wireless technology infrastructure have an important place of making follow-up health everywhere and every time because these devices were using in the health monitoring systems. In this study, Arduino an open-source microcontroller card was used in which a sample sugar measuring device was connected in series. In this way, the glucose data (glucose ratio, time) obtained with the glucometer is transferred to the mobile device based on the Android operating system with the Bluetooth technology channel. A mobile application was developed using the Apache Cordova framework for listing data, presenting graphically and reading data over Arduino. Apache Cordova, HTML, Javascript and CSS are used in coding section. The data received from the glucometer is stored in the local database of the mobile device. It is intended that people can transfer their measurements to their mobile device by using wireless technology and access the graphical representations of their data. In this context, the aim of the study is to be able to perform health monitoring by using different wireless technologies in mobile devices that can respond to different wireless technologies at present. Thus, that will contribute the other works done in this area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arduino" title="Arduino">Arduino</a>, <a href="https://publications.waset.org/abstracts/search?q=Bluetooth" title=" Bluetooth"> Bluetooth</a>, <a href="https://publications.waset.org/abstracts/search?q=glucose%20measurement" title=" glucose measurement"> glucose measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20health%20monitoring" title=" mobile health monitoring"> mobile health monitoring</a> </p> <a href="https://publications.waset.org/abstracts/79642/transferring-data-from-glucometer-to-mobile-device-via-bluetooth-with-arduino-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79642.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Bluetooth Communication Protocol Study for Multi-Sensor Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joao%20Garretto">Joao Garretto</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20J.%20Yarwood"> R.

BLE’s energy efficiency characteristic, smart mobiles interoperability, and Over the Air (OTA) capabilities are essential features for ultralow-power devices, which are usually designed with size and cost constraints. Most current research regarding the power analysis of BLE devices focuses on the theoretical aspects of the advertising and scanning cycles, with most results being presented in the form of mathematical models and computer software simulations. Such computer modeling and simulations are important for the comprehension of the technology, but hardware measurement is essential for the understanding of how BLE devices behave in real operation. In addition, recent literature focuses mostly on the BLE technology, leaving possible applications and its analysis out of scope. In this paper, a coin cell battery-powered BLE Data Acquisition Device, with a 4-in-1 sensor and one accelerometer, is proposed and evaluated with respect to its Power Consumption. First, evaluations of the device in advertising mode with the sensors turned off completely, followed by the power analysis when each of the sensors is individually turned on and data is being transmitted, and concluding with the power consumption evaluation when both sensors are on and respectively broadcasting the data to a mobile phone. The results presented in this paper are real-time measurements of the electrical current consumption of the BLE device, where the energy levels that are demonstrated are matched to the BLE behavior and sensor activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bluetooth%20low%20energy" title="bluetooth low energy">bluetooth low energy</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20analysis" title=" power analysis"> power analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=BLE%20advertising%20cycle" title=" BLE advertising cycle"> BLE advertising cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20node" title=" wireless sensor node"> wireless sensor node</a> </p> <a href="https://publications.waset.org/abstracts/156771/bluetooth-communication-protocol-study-for-multi-sensor-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156771.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> An Indoor Guidance System Combining Near Field Communication and Bluetooth Low Energy Beacon Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rung-Shiang%20Cheng">Rung-Shiang Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei-Jun%20Hong"> Wei-Jun Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jheng-Syun%20Wang"> Jheng-Syun Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kawuu%20W.%20Lin"> Kawuu W.

However, while such services are easily implemented in outdoor environments using Global Positioning System (GPS) technology, a requirement still exists for accurate localization and guidance schemes in indoor settings. Accordingly, the present study presents a methodology based on GPS, Bluetooth Low Energy (BLE) beacons, and Near Field Communication (NFC) technology. Through establishing graphic information and the design of algorithm, this study develops a guidance system for indoor and outdoor on smartphones, with aim to provide users a smart life through this system. The presented system is implemented on a smartphone and evaluated on a student campus environment. The experimental results confirm the ability of the presented app to switch automatically from an outdoor mode to an indoor mode and to guide the user to the requested target destination via the shortest possible route. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beacon" title="beacon">beacon</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor" title=" indoor"> indoor</a>, <a href="https://publications.waset.org/abstracts/search?q=BLE" title=" BLE"> BLE</a>, <a href="https://publications.waset.org/abstracts/search?q=Dijkstra%20algorithm" title=" Dijkstra algorithm"> Dijkstra algorithm</a> </p> <a href="https://publications.waset.org/abstracts/49106/an-indoor-guidance-system-combining-near-field-communication-and-bluetooth-low-energy-beacon-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49106.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> Android – Based Wireless Electronic Stethoscope</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aw%20Adi%20Arryansyah">Aw Adi Arryansyah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using electronic stethoscope for detecting heartbeat sound, and breath sounds, are the effective way to investigate cardiovascular diseases. On the other side, technology is growing towards mobile. Almost everyone has a smartphone. Smartphone has many platforms. Creating mobile applications also became easier. We also can use HTML5 technology to creating mobile apps. Android is the most widely used type. This is the reason for us to make a wireless electronic stethoscope based on Android mobile. Android based Wireless Electronic Stethoscope designed by a simple system, uses sound sensors mounted membrane, then connected with Bluetooth module which will send the heart auscultation voice input data by Bluetooth signal to an android platform. On the software side, android will read the voice input then it will translate to beautiful visualization and release the voice output which can be regulated about how much of it is going to be released. We can change the heart beat sound into BPM data, and heart beat analysis, like normal beat, bradycardia or tachycardia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless" title="wireless">wireless</a>, <a href="https://publications.waset.org/abstracts/search?q=HTML%205" title=" HTML 5"> HTML 5</a>, <a href="https://publications.waset.org/abstracts/search?q=auscultation" title=" auscultation"> auscultation</a>, <a href="https://publications.waset.org/abstracts/search?q=bradycardia" title=" bradycardia"> bradycardia</a>, <a href="https://publications.waset.org/abstracts/search?q=tachycardia" title=" tachycardia"> tachycardia</a> </p> <a href="https://publications.waset.org/abstracts/36762/android-based-wireless-electronic-stethoscope" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36762.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">347</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Wireless Based System for Continuous Electrocardiography Monitoring during Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Bensafia">K.

This wireless recording system allows us to visualize and monitor the state of the heart’s health during a surgery, even if the patient is moved from the operating theater to post anesthesia care unit. The acquired signal is transmitted via a Bluetooth unit to a PC where the data are displayed, stored and processed. To test the reliability of our system, a comparison between ECG signals processed by a conventional ECG monitoring system (Datex-Ohmeda) and by our wireless system is made. The comparison is based on the shape of the ECG signal, the duration of the QRS complex, the P and T waves, as well as the position of the ST segments with respect to the isoelectric line. The proposed system is presented and discussed. The results have confirmed that the use of Bluetooth during surgery does not affect the devices used and vice versa. Pre- and post-processing steps are briefly discussed. Experimental results are also provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocardiography" title="electrocardiography">electrocardiography</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20system" title=" wireless system"> wireless system</a> </p> <a href="https://publications.waset.org/abstracts/79677/wireless-based-system-for-continuous-electrocardiography-monitoring-during-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79677.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">370</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Usability Assessment of a Bluetooth-Enabled Resistance Exercise Band among Young Adults</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lillian%20M.%20Seo">Lillian M.

Batsis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Resistance-based exercises effectively enhance muscle strength, which is especially important in older populations as it reduces the risk of disability. Our group developed a Bluetooth-enabled handle for resistance exercise bands that wirelessly transmits relative force data through low-energy Bluetooth to a local smartphone or similar device. The system has the potential to measure home-based exercise interventions, allowing health professionals to monitor compliance. Its feasibility has already been demonstrated in both clinical and field-based settings, but it remained unclear whether the system’s usability persisted upon repeated use. The current study sought to assess the usability of this system and its users’ satisfaction with repeated use by deploying the device among younger adults to gather formative information that can ultimately improve the device’s design for older adults. Methods: A usability study was conducted in which 32 participants used the above system. Participants executed 10 repetitions of four commonly performed exercises: bicep flexion, shoulder abduction, elbow extension, and triceps extension. Each completed three exercise sessions, separated by at least 24 hours to minimize muscle fatigue. At its conclusion, subjects completed an adapted version of the usefulness, satisfaction, and ease (USE) questionnaire – assessing the system across four domains: usability, satisfaction, ease of use, and ease of learning. The 20-item questionnaire examined how strongly a participant agrees with positive statements about the device on a seven-point Likert scale, with one representing ‘strongly disagree’ and seven representing ‘strongly agree.’ Participants’ data were aggregated to calculate mean response values for each question and domain, effectively assessing the device’s performance across different facets of the user experience. Summary force data were visualized using a custom web application. Finally, an optional prompt at the end of the questionnaire allowed for written comments and feedback from participants to elicit qualitative indicators of usability. Results: Of the n=32 participants, 13 (41%) were female; their mean age was 32.4 ± 11.8 years, and no participants had a physical impairment. No usability questions received a mean score < 5 of seven. The four domains’ mean scores were: usefulness 5.66 ± 0.35; satisfaction 6.23 ± 0.06; ease of use 6.25 ± 0.43; and ease of learning 6.50 ± 0.19. Representative quotes of the open-ended feedback include: ‘A non-rigid strap-style handle might be useful for some exercises,’ and, ‘Would need different bands for each exercise as they use different muscle groups with different strength levels.’ General impressions were favorable, supporting the expectation that the device would be a useful tool in exercise interventions. Conclusions: A simple usability assessment of a Bluetooth-enabled resistance exercise band supports a consistent and positive user experience among young adults. This study provides adequate formative data, assuring the next steps can be taken to continue testing and development for the target population of older adults. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bluetooth" title="Bluetooth">Bluetooth</a>, <a href="https://publications.waset.org/abstracts/search?q=exercise" title=" exercise"> exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20health" title=" mobile health"> mobile health</a>, <a href="https://publications.waset.org/abstracts/search?q=mHealth" title=" mHealth"> mHealth</a>, <a href="https://publications.waset.org/abstracts/search?q=usability" title=" usability"> usability</a> </p> <a href="https://publications.waset.org/abstracts/103152/usability-assessment-of-a-bluetooth-enabled-resistance-exercise-band-among-young-adults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103152.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">117</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Solvent-Free Conductive Coatings Containing Chemically Coupled Particles for Functional Textiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jagadeshvaran%20P.%20L.">Jagadeshvaran P.

There is a legitimate need to develop strategies and materials to combat this issue, otherwise leading to dreadful consequences. Functional textiles have emerged as the modern materials to help attenuate EM waves due to the numerous advantages – flexibility being the most important. In addition to this, there is an inherent advantage of multiple interfaces in coated fabrics that can engender significant attenuation. Herein we report a coating having multifunctional properties – capable of blocking both UV and EM radiation (predominantly of the microwave frequencies) with flame-retarding properties. The layer described here comprises iron titanate(FT) synthesized from its sustainable precursor – ilmenite sand and carbon nanotubes (CNT) dispersed in waterborne polyurethane. It is worth noting that FT's use as a multifunctional material is being reported for the first time. It was observed that a single layer of coated fabric shows EMI shielding effectiveness of -40 dB translating to 99.99% attenuation and similarly a UV blocking of 99.99% in the wavelength ranging from 200-400 nm. The microwave shielding properties of the fabric were demonstrated using a Bluetooth module – where the coated fabric was able to block the incoming Bluetooth signals to the module from a mobile phone. Besides, the coated fabrics exhibited phenomenal enhancement in thermal stability - a five percent increase in the limiting oxygen index (LOI) was observed upon the application of the coating. Such exceptional properties complement cotton fabrics' existing utility, thereby extending their use to specialty applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multifunctional%20coatings" title="multifunctional coatings">multifunctional coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=EMI%20shielding" title=" EMI shielding"> EMI shielding</a>, <a href="https://publications.waset.org/abstracts/search?q=UV%20blocking" title=" UV blocking"> UV blocking</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20titanate" title=" iron titanate"> iron titanate</a>, <a href="https://publications.waset.org/abstracts/search?q=CNT" title=" CNT"> CNT</a>, <a href="https://publications.waset.org/abstracts/search?q=waterborne%20polyurethane" title=" waterborne polyurethane"> waterborne polyurethane</a>, <a href="https://publications.waset.org/abstracts/search?q=cotton%20fabrics" title=" cotton fabrics"> cotton fabrics</a> </p> <a href="https://publications.waset.org/abstracts/148480/solvent-free-conductive-coatings-containing-chemically-coupled-particles-for-functional-textiles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148480.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Smart Oxygen Deprivation Mask: An Improved Design with Biometric Feedback</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevin%20V.%20Bui">Kevin V.

This produces the same effect as higher altitudes where lower pressure leads to reduced respiratory flow. Both increased resistance with restricting valves and reduce the pressure of higher altitudes make breathing difficultier and force breathing muscles (diaphragm and intercostal muscles) working harder. The process exercises these muscles, improves their strength and results in overall better breathing efficiency. Currently, these oxygen deprivation masks are purely mechanical devices without any electronic sensor to monitor the breathing condition, thus not be able to provide feedback on the breathing effort nor to evaluate the lung function. That is part of the reason that these masks are mainly used for high-level athletes to mimic training in higher altitude conditions, not suitable for patients or customers. The design aims to improve the current method of oxygen deprivation mask to include a larger scope of patients and customers while providing quantitative biometric data that the current design lacks. This will be accomplished by integrating sensors into the mask’s breathing valves along with data acquisition and Bluetooth modules for signal processing and transmission. Early stages of the sensor mask will measure breathing rate as a function of changing the air pressure in the mask, with later iterations providing feedback on flow rate. Data regarding breathing rate will be prudent in determining whether training or therapy is improving breathing function and quantify this improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oxygen%20deprivation%20mask" title="oxygen deprivation mask">oxygen deprivation mask</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20function" title=" lung function"> lung function</a>, <a href="https://publications.waset.org/abstracts/search?q=spirometer" title=" spirometer"> spirometer</a>, <a href="https://publications.waset.org/abstracts/search?q=Bluetooth" title=" Bluetooth"> Bluetooth</a> </p> <a href="https://publications.waset.org/abstracts/69291/smart-oxygen-deprivation-mask-an-improved-design-with-biometric-feedback" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69291.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">218</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Development and Evaluation of a Portable Ammonia Gas Detector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaheon%20Gu">Jaheon Gu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wooyong%20Chung"> Wooyong Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Mijung%20Koo"> Mijung Koo</a>, <a href="https://publications.waset.org/abstracts/search?q=Seonbok%20Lee"> Seonbok Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Gyoutae%20Park"> Gyoutae Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangguk%20Ahn"> Sangguk Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiesik%20Kim"> Hiesik Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jungil%20Park"> Jungil Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a portable ammonia gas detector for performing the gas safety management efficiently.

They are integrated with complex electronics and are worn very close to the body. Optical measurements and limitation of the maximum light density are needed. Smart watches are equipped with a laser diode or control different body currents. Special glasses generate readable text information that is received via radio transmission. Small high-performance batteries (lithium-ion/polymer) supply the electronics. All these products have been tested and evaluated for risk. These products must, for example, meet the requirements for electromagnetic compatibility as well as the requirements for electromagnetic fields affecting humans or implant wearers. Extensive analyses and measurements were carried out for this purpose. Many users are not aware of these risks. The result of this study should serve as a suggestion to do it better in the future or simply to point out these risks. Commercial LED warning vests, LED hand and foot-bands, illuminated surfaces with inverter (high voltage), flashlights, smart watches, and Bluetooth smart glasses were checked for risks. The luminance, the electromagnetic emissions in the low-frequency as well as in the high-frequency range, audible noises, and nervous flashing frequencies were checked by measurements and analyzed. Rechargeable lithium-ion or lithium-polymer batteries can burn or explode under special conditions like overheating, overcharging, deep discharge or using out of the temperature specification. Some risk analysis becomes necessary. The result of this study is that many smart wearables are worn very close to the body, and an extensive risk analysis becomes necessary. Wearers of active implants like a pacemaker or implantable cardiac defibrillator must be considered. If the wearable electronics include switching regulators or inverter circuits, active medical implants in the near field can be disturbed. A risk analysis is necessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=safety%20and%20hazards" title="safety and hazards">safety and hazards</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20safety" title=" electrical safety"> electrical safety</a>, <a href="https://publications.waset.org/abstracts/search?q=EMC" title=" EMC"> EMC</a>, <a href="https://publications.waset.org/abstracts/search?q=EMF" title=" EMF"> EMF</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20medical%20implants" title=" active medical implants"> active medical implants</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20radiation" title=" optical radiation"> optical radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=illuminated%20warning%20vest" title=" illuminated warning vest"> illuminated warning vest</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20luminescent" title=" electric luminescent"> electric luminescent</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20and%20head%20lamps" title=" hand and head lamps"> hand and head lamps</a>, <a href="https://publications.waset.org/abstracts/search?q=LED" title=" LED"> LED</a>, <a href="https://publications.waset.org/abstracts/search?q=e-light" title=" e-light"> e-light</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20batteries" title=" safety batteries"> safety batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20density" title=" light density"> light density</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20glare%20effects" title=" optical glare effects"> optical glare effects</a> </p> <a href="https://publications.waset.org/abstracts/109112/measurements-for-risk-analysis-and-detecting-hazards-by-active-wearables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109112.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">110</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Perfectly Keyless Commercial Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shubha%20T.">Shubha T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Latha%20H.%20K.%20E."> Latha H.

Owners of company automobile fleets can electronically distribute car keys to staff members, possibly granting access for a given day or length of time. Customers no longer need to physically pick up car keys at a rental desk because automobile owners can digitally transfer keys with them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NFC" title="NFC">NFC</a>, <a href="https://publications.waset.org/abstracts/search?q=BLE" title=" BLE"> BLE</a>, <a href="https://publications.waset.org/abstracts/search?q=CCC" title=" CCC"> CCC</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20key" title=" digital key"> digital key</a>, <a href="https://publications.waset.org/abstracts/search?q=OEM" title=" OEM"> OEM</a> </p> <a href="https://publications.waset.org/abstracts/171531/perfectly-keyless-commercial-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171531.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Cavitas Sensors into Human Cavities: Soft-Contact Lens and Mouthguard Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kohji%20Mitsubayashi">Kohji Mitsubayashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Takahiro%20Arakawa"> Takahiro Arakawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kohji%20Mitsubayashi"> Kohji Mitsubayashi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> ‘Cavitas sensors’ attached to human body cavities such as a contact lens type and a mouthguard (‘no implantable', ‘no wearable’) attracted attention as self-detachable devices for daily medicine. In this contribution, the soft contact lens glucose sensor for tear sugar monitoring will be introduced. And the mouthguard sensor with dental materials integrated with Bluetooth low energy (BLE) wireless module for real-time monitoring of saliva glucose would also be demonstrated. In the near future, those self-detachable cavitas sensors are expected to improve quality of life in view of the aging of society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cavitas%20sensor" title="cavitas sensor">cavitas sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensor" title=" biosensor"> biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20lens" title=" contact lens"> contact lens</a>, <a href="https://publications.waset.org/abstracts/search?q=mouthguard" title=" mouthguard"> mouthguard</a> </p> <a href="https://publications.waset.org/abstracts/58793/cavitas-sensors-into-human-cavities-soft-contact-lens-and-mouthguard-sensors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58793.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Prototyping a Portable, Affordable Sign Language Glove</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vidhi%20Jain">Vidhi Jain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Communication between speakers and non-speakers of American Sign Language (ASL) can be problematic, inconvenient, and expensive. This project attempts to bridge the communication gap by designing a portable glove that captures the user’s ASL gestures and outputs the translated text on a smartphone. The glove is equipped with flex sensors, contact sensors, and a gyroscope to measure the flexion of the fingers, the contact between fingers, and the rotation of the hand. The glove’s Arduino UNO microcontroller analyzes the sensor readings to identify the gesture from a library of learned gestures. The Bluetooth module transmits the gesture to a smartphone. Using this device, one day speakers of ASL may be able to communicate with others in an affordable and convenient way. <p class="card-text"><strong>Keywords:</strong> <a
