Recent technological advances allowed the word to construct several wearable products that can capture and process the human body bio-signals. The PPG signal becomes one of the most contenders in heart rate monitoring due to their prominent features, flexibility, effectiveness and low costs. This paper present a novel System of PPG Heart rate calculation based on FPGA, using the Pan and Tompkins as...
The paper presents a system that uses Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software to monitor, and to control the state of an electrical machine depending on user imposed limits. In this system, the real-time variables of an electrical machine are measured and transferred to a controller (PC) through Data Acquisition Card (DAQ). The NI USB 6009 DAQ is selected for this project...
The paper suggests very fast electronic solutions for priority buffers that take data from many potential sources, accumulate them in a register, and output the most priority item in run time in such a way that as soon as a new value arrives it is included in the set with all previously received and untreated items and properly handled. It is shown that such circuits are required for real time embedded...
This paper presents experimental results that allow high-performance ports in Zynq microchips to be evaluated taking into account parallel computations and their influence on throughput of FIR filters. All projects are based on Xilinx components. We found that although parallel traffic leads to performance degradation, actual throughput is reduced not very significantly. The results of experiments...
Among the protection mechanisms that ensure the Java Card security, the Byte Code Verifier (BCV) is one of the most important security elements. In fact, embedded applets must be verified prior installation. This prevents ill-formed applet to be loaded. In this article, the behavior of the Oracle BCV towards some unchecked piece of codes is analyzed, and the way to bypass the BCV is highlighted. Then,...
