Health monitoring solution using dedicated ZigBee sensor network

Health monitoring systems using wireless networks has become a constant concern in various fields, not only of medical plan but also in other domains in which bio-signal data collection from field teams, such as: firefighters, rescue service or emergency medical services, is important, especially in areas lacking communications. Mobile wearable sensors allow now more flexibility in collecting and transmitting these data. This paper presents a health monitoring system designed to work using a ZigBee network, suitable to be used in various fields of applications.

Data acquisition and image processing system for surface inspection

This paper presents the hardware and software structures of a proposed data acquisition and processing system, which is designated to perform an automated inspection of roads pavement condition. The system was designed to gather information from multiple sources - laser-based imaging systems for road profiling, cameras for environmental images, proximity sensors, all information being spatially correlated by means of odometry and geolocation. The system was tested while performing real road inspection, and some results are presented.

LabVIEW brain computer interface for EEG analysis during sleep stages

In this paper is proposed a brain-computer interface. In order to develop and implement this interface, the programming environment LabVIEW was used. In order to recognize a K complex in the EEG signal, a simple detector was created, using Peak Detector VI in LabVIEW. The detector receives the representation of the power spectrum of the signal and determines the locations and the amplitudes of signals above a certain limit (the limit can be set by moving the horizontal bar in the power spectrum). Then the code determines if the peak correspond to those which designate a K complex. Following these experimental achievements where an EEG signal was used, it was determined that one could reliably observe a K complex in the data from the sleep spindles, focusing on only 2 peaks in the power spectrum. The first peak should appear between 0,5 and 1.50 Hz, having an amplitude exceeding 65 units, while the second peak should appear between 5 and 10 Hz, having an amplitude of at least 30 units.

Multiple sensor software and hardware architecture for field robots

Applications in Field Robotics often require synchronous acquiring various environment information using multiple sensors and devices, including digital cameras. For such applications, this paper proposes a software architecture that is designed to cope with large amount of mixed type data, acquired with various sample times, and gathered from multiple sensors and sensing devices. By allowing the integration of cameras having widely available communication interfaces, such as USB and Ethernet, the presented architecture is intended to allow a cost-effective and flexible robotic system configuration, providing consistent data and loss-less images to be further used in automated data processing. The paper presents the software design, which was implemented in LabVIEW environment, and an illustrative hardware configuration.

Use of pedagogical agents to build multiple choice equations for an electric workshop based on LabVIEW

e-Learning, with its various aspects, represents a major trend in education. This paper presents a solution to extend the traditional multiple choice tests to effectively graphic design of calculus equations for an electric workshop. Equation built procedure was augmented using animated pedagogical agents to increase the effectiveness of learning and practical skills and improve the attractive aspect of the process. The implemented algorithms and software were tested on two groups of bachelor degree students from Electrical Engineering Faculty, proving useful results and ways to develop further works.

Platform for bio-monitoring of vital parameters in critical infrastructures operation

The objective of the present scientific research was to develop a bio-monitoring platform for the supervision of personnel working in the critical infrastructure tested in a laboratory based on virtual reality simulations. The role of this platform is to collect a set of signals in order to determine the optimal physiological profile of personnel during testing in virtual reality simulations (for real situations). From biomedical perspective, in developing this platform there are several main directions of interest including: the development of software solutions for biosignal processing derived from the multiple biosensors, the analysis of hardware and software solutions for bio-information acquisitions and the identification of the most efficient solutions. Also, it has followed the development of software and hardware solutions for seamless integration of all monitoring equipment in order to develop a complex integrated system. This platform will help in developing new training and health evaluation criteria very useful for correct conclusions about predictive character regarding the responses of the personnel in the real professional situations.

Software Solution Implementation for Regional Balancing Mechanism of Electrical Energy

The aim of this paper is to present how the Regional Balancing Mechanism (RBM) can be facilitated by a specially developed software solution.
