Recently there is a number of scenarios such as vehicle platooning, UAV swarms and cooperative robots, where a group of autonomous entities needs to make joint decisions to operate effectively. Distributed agreement protocols can play a key role to establish a common view on context parameters and to coordinate joint actions. Due to the harsh environmental conditions in some of these scenarios and...
The aim of this work is to present newly developed electro-technological and signal processing EEG signal acquisition systems with increasingly advanced functions. EEG Electroencephalogram (EEG) signals are the recorded potentials of the collective activity of synchronized cortical cell populations chained to an external system.
The aim of this paper is to present the newly developed electro-technological and signal processing ideas that can provide an improved brain-computer interface (BCI) system with significant advance in its performance. A BCI system allows to record bio-signals. Technologies based on the information extracted from these bio-signals are able to act on the environment. The brain activity can be used to...
Advancement in micro-electro mechanical system (MEMS) that integrate mechanical system, sensor, actuator, and electronics has contributed to significant improvement of automation system including security and safety system. This paper will propose a framework of integrated security and safety system that combines microembedded system and computer based system. The framework is designed and developed...
Intelligent transport system (ITS) deals with the remote sensing as well as access to the Internet and multimedia on the move. There is a need for a system that supports both remote sensing and communication aspects with simple and reconfigurable hardware. In the present work MATLAB/SIMULINK based modeling of such a system is done based on DSSS. Hardware realization of this model is achieved through...
In this paper we present a solar energy harvesting circuit for low-power applications describing circuit architecture and guidelines for an optimal design. We evaluate the performance of two implemented prototypes intended to power a wireless embedded system under different light intensities and different switching frequencies. Measurements show that higher switching frequencies allow reaching the...
Electrocardiogram (ECG) and Pressure blood is a main source for doctors to diagnose the health condition and pathology of heart. The magnitudes of ECG signals are usually approximate 1 mV. The Electrocardiogram signals are affected by environment noises. The mostly sources of these errors are the power line of 50 HZ. In this paper we present an advance develop of Wireless pads using embedded system...
The research field of partitioning for electronic systems started to attract significant attention of scientists about fifteen years ago. Gaining ever more importance due to the rampant growth and shortening design cycles in wireless embedded systems, a multitude of formulations for this problem has emerged. Accordingly, a similar multitude can be found in the number of strategies that address system...
Lots of emerging wireless technologies has evolved with their own advantages and disadvantages. Through the convergence of technologies, one can eliminate the drawbacks of the other. In this work, the authors first established limitations of the popular WiFi (IEEE 802.11 wireless router) radio in terms of high end multimedia data services and then redesign the IEEE 802.11 N(draft) wireless router...
To satisfy the need for teaching wireless and mobile embedded system design, we have designed a complete laboratory, together with the related curriculum updates. We present the lab infrastructure for developing skills spanning physical design of the devices, protocol and application frameworks, as well as the practical issues in its design and use.
The authors present an innovative wireless embedded system for logistic applications: it is a prototype of a portable appliance to manage operations in production activity. The system is based on a wearable device which is able to read products codes and allows the system to guide users through the different phases of warehouse's everyday life; by means of wireless IEEE 802.15.4 standard - on the...
In this paper we suggest a wireless embedded system for estimating the closeness and the interaction time between mobile and fixed units for personal safety applications. In particular, the system provides a technological support during emergency or critical situations - where personnel has to safety move in a critical dynamic scenario - by automatically delimiting a dangerous area previously characterised...
