Patent Review:

This patent describes the process of working on ECG real-time detection, and wireless transmission of ECG. In order to achieve this purpose a portable ECG monitor which achieves the purpose of cardiac disease remote monitoring, and which will be used in the physical and psychological disease surveillance in smart home system was developed.A portable ECG Monitor was used and interfaced with Digital Signal Processor

Digital Signal Processor used was TMS320F2812. It served as the core controller and  completed the tasks like signal collection, storage, processing, waveform display and transmission.

Paper review : 

This paper illustrates a low-cost method for online acquisition of ECG signal for storage and processing using a MATLAB-based Graphical User Interface (GUI). The single lead ECG is sampled and after digitization, fed to a microcontroller-based embedded system to convert the ECG data to a serial bit-stream. This serial data stream is then transmitted to a desktop Personal Computer and a software which stores it automatically in a temporary data file. The original ECG data is reconstructed from the digital data set by a conversion formula. The MATLAB-based GUI is designed to perform online analysis on the ECG data to compute the different time-plane features and display the same on the GUI along with the ECG signal plot.

Group IEEE Paper : Analysis and Filtering of ECG, EMG and EEG signals.

We as a group prepared IEEE format paper on the topic of Analysis and Filtering of ECG, EMG and EEG signals.

We studied how these signals are obtained as input and filtered using DSP processor and MATLAB.

Plagiarism was checked and the resukt obtained was 96% unique.
