The river pollution has become a prominently environmental problem to human survival. Thus it is in urgent demand for real-time monitoring of river water. However, traditional methods have some disadvantages such as complicated instrument, high cost and cumbersome operation. Herein, we developed wireless conductivity sensor, which forms a monitoring network system based on ZigBee. The node of the...
The paper presents experimental research related to pH measuring and to the design of a system of pH monitoring. The paper is structured on three parts. The first part presents the principle of measuring the pH of a solution matter, the transducer structure and of the adaptor used. The second part is dedicated to the experimental research effectuated aiming at the use of PACTware software environment...
In the paper, a new version of a multichannel ECG measuring system ProCardio is introduced. The system was designed for measurement, processing, and evaluation of surface electrocardiograms using up to 144 passive or active ECG electrodes. For fast and convenient placement of electrodes, self-adhesive stripes with eight electrodes are used. To minimize the capacitive coupling and guarantee maximal...
In this paper, we propose a two electrodes configuration for noncontact long-term cardiac monitoring. Our system was designed as an alternative to Holter devices. Unlike a traditional long-term monitoring equipment, our system is stationary and non-contact, the cardiac signal is acquired through a capacitive coupling between the sensor and the subject's body. The proposed system is the first prototype...
Frequent monitoring is required for chronically ill cardiac patients to ensure superior treatment. This paper presents a low-cost, novel wearable electrocardiogram (ECG) measuring unit for consistent use. In this study, the ECG signal is accumulated by a three electrode data acquisition system and measured by an integrated signal conditioning block AD8232. The analog signal from AD8232 is converted...
A growing number of elderly people in Poland and Europe forces to look for new solutions for the continuous monitoring of people health state. This approach allows elderly for an action in case of dangerous situations for older patients' life (state before heart attack or stroke, etc.). The system for continuously monitoring the health state also allows a quick action of first contact doctors in the...
Marine electromagnetism survey which is divided into the natural field source (MT) and artificial field source (CSEM) is one of the hot spots in the field of offshore oil and gas exploration, especially in the deep sea. Low frequency, wide band and weak electric field signal acquisition which generally uses Ag/AgCl non-polarized electrode and ultra-low noise amplifier is one of the key technologies...
A growing number of elderly people in Poland and Europe forces us to look for new solutions for the continuous monitoring of their health state. This approach allows an early action in case of dangerous situations for elderly persons' life (state before a heart attack or a stroke, etc.). The system for continuously monitoring the health state also allows a quick action of first contact doctors in...
The increasing demand for innovative systems, used for monitoring the biomedical parameters and comfortable for the patients, leads to the provision of better and better solutions. This paper presents the latest system design for the measurement of psychophysiological parameters for comprehensive use, developed at the Institute of Medical Technology and Equipment in Zabrze (ITAM), in light of previous...
One of the key factors for successful cochlear implantation is the correct fitting of the stimulation values. Once the cochlear implant is activated, obtaining a fitting that maximizes chances of complete rehabilitation is a long and difficult task, especially in the case of pediatric patients. Fitting protocols and principles vary from one specialist to another. Based on the experience gained through...
This paper presents the development of a system for recording and analysis of three electrogastrogram (EGG) signals and two monitor signals: respiration and body movement and its route along the stomach wall. The signals were recorded from three pairs of electrodes located on the external abdominal wall, filtered with a low pass filter with cut off frequency of 1 Hz and acquired with a sampled frequency...
Amongst the factors that benefit preventive treatment of cardiac patients are early detection and correct identification of cardiac arrhythmia patterns. However, in the State of Michoacán, Mexico, cardiac patients are seldom monitored as part of routine diagnostic in public health institutions due to the lack of ECG monitoring equipment. This paper describes the design and construction of an Ambulatory...
A compact and portable device was designed for preliminary study of patch type ambulatory 3-electrode ECG monitoring system for limb leads and augmented unipolar limb leads signal analysis. The developed system also can measure and send the acceleration signals wirelessly during daily life to analyze the user's information. The 3-electrode system is feasible to provide the information of limb leads...
The paper presents an innovative distributed measurement system for wine fermentation monitoring. The system intelligence is distributed among some Local Measurement Units (LMU) and a Manager Unit (MU). LMU's, made by a biosensor with its conditioning circuit plus a signal acquisition and processing module, can be integrated in complex multi-sensor schemes for process monitoring under control of a...
In this paper we describe the development of a limited lead BSPM system which is based around a commercial 12-lead ECG acquisition unit and a smartphone. We repositioned the six precordial leads to allow for better information capture and hence more accurate reconstruction of BSPMs. The new lead positions were chosen using a data mining based lead selection algorithm. We developed two specific lead...
We assessed the effects of the addition of dynamic visual elements and sounds to a levee patroller training game on the appraisal of the environment and weather conditions, the engagement of the users and their performance. Results show that the combination of visual dynamics and sounds best conveys the impression of severe weather conditions and most strongly influences the appraisal of the environment...
