Design of an Economic Home Based BP Monitor
Students: Saeed Balfakeeh, Mufleh Al-Sulami, Waheeb Abdulwahid
High blood pressure is a major problem today and the biggest difficulty with this serious and often life-threatening condition is that it rarely displays any symptoms at all. It can sometimes lead to the destruction of the arteries of the heart by the increase of fatty lumps that block the coronary artery. High blood pressure (Hypertension) is widely known as the "silent killer". It can be present at the person without realizing it most of the time. Therefore, after reviewing the factors of the common Heart disease we realize that it is an extremely dangerous disease which must be monitored on a regular basis daily in order to keep the blood pressure within the normal range and avoid the undesired consequences. This is usually done by visiting the hospital to get the medical monitoring which requires high cost instruments.
This is the final report which include all the information of our assigned project starting from the beginning of the first step we have been through to the last step.Our objective is to build ECONOMICAL HOME BASED BLOOD PRESSURE MONITOR .
The specifications of our design shortly are as the following:
Automatic blood pressure measurement after turning the power ON.
Compact and light design, easy to carry
Safe to patient
Fast response (less than 50 Hz).
We select our design based on important criteria for us: Low cost and to be Improvable design.
For designing our project we have three alternative solutions, they are:
1. Blood pressure monitor.
2. Measure blood pressure continuously.
3. Economical home base blood pressure monitor(our project)
After we comparing between all the existing alternative solutions, we have decided building our own project which is ECONOMICAL HOME BASED BLOOD PRESSURE MONITOR to be the best solution and we selected it.

Design of Automatic Arrhythmia Detector using Analysis of ECG Signals
Students: Ahad Masoud, Ibrahim Shaibah, Rayan Kashgari, and Ali Aleryani
Physicians diagnose the functionality of the heart from reading the different amplitudes and length of different time segments of the ECG waveform. Little work is done so far in understanding the frequency contents of this signal. Time-frequency algorithms observe signals in both time and frequency as well. This analysis provides a different view for signals and it is becoming very popular.
The objective of this project is to design a software that automatically detect arrhythmias using analysis of ECG signals. The input of the software is an ECG signal taken from a patient or ECG simulator. Features representing the normal ECG must be countable. Accuracy of detecting arrhythmias should be more than 90%. The classifier must detect arrhythmia in less than 2 seconds. The program needs to be an executable file under windows operating system and does not require additional special software installed. The program should use a graphical user interface (GUI) that is easy to use by the customer.
The ECG signals can be analyzed using Time Domain Analysis, Frequency Domain Analysis, or Time Frequency Analysis. Unlike Time Domain Analysis and Frequency Domain Analysis, whom only represent signals from one perspective, which is time or frequency, Time Frequency Analysis takes advantage of both worlds by representing signals in time and frequency. This provides an additional insight over the heart's ECG signal, and detects different abnormalities in the heart that can't be detected using time analysis or frequency analysis alone, making Time Frequency Analysis the best solution.
After implementation, the software achieved an accuracy of 96.7% in detecting normal ECG waveforms, 98.2% in detecting Arterial Fibrillation ECG waveforms, and 96.5% in detecting Superventricle ECG waveforms. Execution time for a 1 minute ECG recording was found to be 0.92 seconds.
Design of Economic Home-Based Computer Interfaced ECG Monitor
Students: Mohammed Oghly, Fahad Sahhari, Ahmad Jiman, and Milbis Alqouzi
Sometimes a person experiences chest pain, fatigue or dizziness that only lasts for a few minutes. Most people ignore these infrequent pains which may be symptoms of cardiac diseases such as heart attacks and arrhythmias. These diseases could be diagnosed by monitoring the electrical activity of the heart (ECG), but if the symptoms are not there while the heart is monitored, the ECG could turn out absolutely normal. The “Economic Home-Based Computer Interfaced ECG Monitor” solves this problem by allowing the patient to monitor the ECG signal at home, when the symptoms occur. The device is affordable and easy-to-use by almost anyone in the public. By using a normal computer (PC or laptop) it will be able to monitor, store, retrieve the ECG signal and calculate the heart rate of the patient. It allows the specialized physician to open and read the stored file of the ECG signal to diagnose the patient more accurately.
The project contains three main parts ; the ECG circuit, the interface circuit and a computer program. The ECG circuit has a frequency range of 0.5-200 Hz to pick up the ECG signals from the body. The computer program displays, stores, retrieves the ECG signal and calculates the heart rate.
This project is considered economic compared to typical ECG devices that are used nowadays in hospitals, since the solutions for this project were selected to be as economical as possible. The alternative solutions for the interface circuit were: 1)USB 2)RS-232 and 3)Bluetooth, as for the computer program: 1)C++ 2)Java and 3)MATLAB. The USB (using PIC) interface circuit and the MATLAB computer language were selected for this “Economic Home-Based Computer Interfaced ECG Monitor” project.
Blood Pressure Based Motor Control for Diabetic Foot Treatement
Students: Fawzi Alharthi, Yasin Atteia, Abdulhamid Nashashgi, and Sultan Qasim
Diabetic disease became disease of century. Statistics show that number of patients with diabetic disease is increasing. Diabetes is a condition whereby the body is not able to regulate levels of glucose (a sugar) in the blood, resulting in too much glucose being present in the blood. Diabetes occurs when there is too much glucose in the blood. Or, to be more precise, diabetes occurs when the body is unable to regulate the level of glucose in the blood, resulting in too much glucose being present.
Over time, the high blood glucose levels present, as a result of diabetes, may cause serious complications, such as damage blood vessels and nerve cells, leading to damaged eyes, nerves and kidneys and an increased risk of heart attack, stroke, impotence, and foot problems. That is why society care about this topic and doing research and development toReduce its effects as possible.
