Preliminary Assessment of a Fire Escape Hood Integrated with Positioning and Motion Sensors

Wearable electronics appear more frequently in the personal protective equipment market (PPE) primarily to assure information and alarm functions for the user. However, despite their advantages, there remain doubts concerning the level of protection that these devices can guarantee and their conformity to requirements laid down in PPE legislation. This paper investigates the factors that need to be assessed to confirm that such devices function correctly under anticipated use conditions. To this end, we considered a case study of an air-purifying fire escape respirator (APER) integrated with a radio-based positioning system and alarming device. In particular, we examined the parameters associated with the operation of the alarm and the information functions (the visibility and audibility of the alarm signals and the radio signal strength of the positioning system). This study provides evidence that the anticipated use conditions and the APER construction have a combined effect on the correct functioning of the embedded electronics. Based on these findings, we identified additional requirements that should be considered by PPE manufacturers at the design stage as well as by health and safety practitioners when evaluating the protection levels of PPE with embedded electronics.

Embedded Electronics Applied in Remote Laboratories Using NodeJs

A description of the implementation of integrated practical work in a remote laboratory was presented in this paper. The student, in real time, can access an online web page in order to manipulate a practical work of digital electronics. This work is based on the use of an embedded system PcDuino. The hardware architecture and software solutions are described, as well as the supervision tool that allows the student to follow changes in the output states of the Practical Work remotely.

A new class of material

Demand for sensors and connectivity solutions has never been greater than it is today, and rapidly diversifying application spaces require circuitry implementations that are new and different from those that have been traditionally available. The mission of Liquid Wire (Portland, Oregon) is to create directly embedded electronics that coexist naturally with functional materials

IoT Based Car Pollution Detection Using Cloud Computing

Air pollution is a critical problem that is currently plaguing Asia in the perilous fight against environmental pollution. It refers to the harmful substances and pollutants in the air that play an essential role in the depletion of the ozone layer while being a grave hazard to the ecological system. A principal cause of air pollution is the increase in vehicular traffic, especially in Asia, that has been noted in recent years. The combustion reaction that occurs when cars burn gasoline leads to the emission of Carbon Monoxide (one of the principal constituents of air pollution). According to many recent studies, Carbon Monoxide is fatal enough to cause health issues which may lead to death in some extreme cases. Thus, it comes as no surprise that regulating car pollution is a paramount step in finding a solution to this global issue. Therefore, we are developing a system using a carbon monoxide sensor (MQ-7) and Arduino Uno microcontroller, which detects the gas emission from the car exhaust. Internet will play an important role in the communication of physical things. Physical objects can be empowered through the embedded electronics into it, to make them smart and at the same time IoT gives the connection among these objects to give high quality of life to the people. Hardware, software components works cooperatively to build the IoT. This technology is used in the development of air pollution detection system.

Intelligent Textiles and its applications: An overview

Intelligent wearable clothing can be seen as textiles that possess the capability of sensing and responding to environmental changes. The clothing sense the physical activity of the person and his environment, monitor and analyze it, and accordingly attempts to respond in most appropriate manner. Intelligent textiles are laced with embedded electronics sensors and other circuitry into fabric thereby resulting in smart outfits capable of an array of diverse applications. Intelligent textiles find applications in defense sectors, railways, firefighters, police, skydivers, sports-persons and other professional activities. The aim of this study is to highlight the protective applications of wearable intelligent textiles and their significance in the present context.
