The QARTOD methodology of a standard sequential string of tests on individual measurements has high applicability to constrained data systems. The QARTOD methodology has the benefit of a coherent and replicable test structure that enables relatively easy expansion into new measurements. However, as data streams become more complex the series of tests described becomes increasingly difficult to analyse...
A real-time remote data acquisition and process monitor system based on ARM and Ethernet is designed for automatic filling line. The whole scheme of the system is analyzed and the hardware and software design of the system is discussed in details. Though obtaining intuitive image video information and analyzing the real-time display data or history date which come from the production line, people...
In this paper, we present a capacitive, MEMS based accelerometer comprising an ultra-low noise CMOS integrated readout-IC and a high precision bulk micro machined sensing element. The resulting accelerometer reaches an acceleration equivalent noise of only 200 ng/fHz, which makes it suitable for seismic measurement that require noise levels significantly below 1 pgAjHz. The design of the sensing element...
The root mean square (rms) measurement of alternating voltage of any waveform is frequently done by means of thermal transfer instruments. The principle of these thermal rms converters is to transfer the heating energy of resistive load to a temperature-sensing element. The dc voltage output of the sensor reflects the amount of electrical power (ac or dc) applied to the input. This paper is addressing...
This paper presents a multifunctional hot-wire based microstructure enabling the design of pressure sensors and wall shear stress sensors for aerodynamic applications. The hotwire is suspended over the substrate using periodic silicon oxide micro-bridges, allowing thermal insulation and mechanical toughness. The microstructure design was exploited to realize both wall shear stress sensors experimented...

The diagnostic information and the prescription of any health discrepancies are generated by checking certain parameters with an expert verified medical database. The health parameters are taken as input via sensors or through the keyboard. The microcontroller based intelligent system is designed with the help of medical data base.
As the number of devices (things) connected to the Internet (Internet of things: IoT) is growing, achieving robust security and privacy (S&P) is becoming increasingly challenging. With the heavy use of medical things (MT), the S&P in the medical domain poses a serious issue that continues to grow. Due to the criticality and sensitivity of the data in the healthcare domain, ensuring...

In this paper we present a new approach for accelerated search of human activity registered by noninvasive sensors. A standard data representation in three combined directions x, y and z for the feature vectors are used as input. A k-NN (k-Nearest Neighbors) classifier is trained with the full 3D descriptors. The aim is to recognize one of the following actions — running, walking, going upstairs and...
Ultrasound offers measurements of parameters encountered in harsh environments such as steam generators, heat exchangers and nuclear reactor primary and secondary systems. But there is a lack of piezo-materials tolerant of high temperatures and nuclear irradiation. Another issue is that transducers are needed that can be left in place on curved surfaces such as pipes and valves. The transducers should...
Touchscreen sensors are widely used in many devices such as smart phones, tablets, laptops, etc. There are many different types of modalities that enable sensing the touch. The dominant technologies on the market are the capacitive, resistive, acoustic or ultrasound, and optical touch systems. None of these technologies are perfect and each has some advantages and disadvantages. Capacitive touch technologies...

The practical application of the accelerometer measurements on the phase-measurement principle of the forming of a signal is justified. The technique of the automatic positioning...
Assisted living and home monitoring systems are gradually becoming a necessity, considering the current trends in population ageing and older adults' desire to continue living independently in their homes and their communities for as long as possible. This paper presents our current achievements regarding the implementation of a cyber-physical system for assisted living and home monitoring, developed...
Air and Water are the most important resources of the planet that we use daily for sustaining life. Air quality affects all living creatures, from trees and plants to animals and people. Air quality, especially in the trend of more industrialized cities and with a rapid growing population of cars, is degrading. Continuous monitoring allows the national administrations to take measures in order to...
