PROGRESS REPORT

Subject: Progress Report (August 1until November 8, 2012.) Development of Graphical User Interfacing using LabVIEW for analysis of the Photoplethsmography signal.

Introduction:

The main goal of this engineering project is to communicate the Photoplethsography sensor with GUI using LabVIEW to detect blood volume changes in the microvascular bed of tissue to measure temperature body and heart beat. This proposal and designation is analyzing the performance of photoplethsmography sensor, which interface with LabVIEW.

Work Completed from August 1 until November 8, 2012:

I have done many researches for my Final Year Project. After discussing on the nature of the project and the objectives, I have come an understanding about the project. So the work plan had been create to guide the whole project progress.

I try to do the progress of my progress as much as I could do. I have plan very details about work and task I need to do later on. I have planned to find out how the photoplethsmography sensor is working. In addition, I have to make some research how do the photoplethsmography sensor and LabVIEW are interfaced in order to get the constant and best result. From now, I have learned basic technique that I can apply in my project.

Problem Encountered:

        

    For the input finger pulse probe and the photoplethsmography sensor, both of it need to be related with each other, but the work for it is still in research and the method for it also still in research so that I can use the most efficient and accurate method. The understanding of LabVIEW for creating the interface with photoplethsmography sensor is still insufficient and need some time to study, on how to use it for output display. I also have to know what kind of port will be the output serial, analog, digital or etc.

Conclusion:

There are several scopes of work for this project; study and identify on how the photoplethsmography sensor can provide an information about the level of temperature of body of a patient by using a non-invasive method, which is photoplethsmography sensor.

PRESENTATION WEEK

This is the project presentation week, for FYP sem 1. All FYP sem 1 students will be at Gemilang Hall starting 2 pm until 5 pm. Each student have two assessors to evaluate their project presentation. For my presentation, I was evaluated by two assessors, first Sir Syamsul Adlan and second Madam Zaridah. I will present the best as I can do without any problems and thanks a lot to our assessors by making our presentation goes smooth and easy.

PRESENTATION PREPARATION

In week 12, all FYP sem 1 students will have their project presentation at Gemilang Hall. The purpose of this presentation was to tell the assessor/evaluator about the project ideas and the objective of producing the project. As a preparation for the presentation, I need to make the presentation slides. The slides must contain the introduction of the project, problem statement, objective, project limits, the work plan and also the methodology. I made the slides and discuss with my supervisor/adviser about it. There were some correction and addition needed to be made before the presentation slides ready to be presented in front of the evaluator.

PROGRESS 8 : BUDGET

BUDGET

Total all costing is RM250.00. All the costing and budget above are the estimation only and all the item and components are not finalize at all because there is only estimation and maybe involve with other component and other circuit or any upgrading to the project.

PROGRESS 7 : WORK PLAN

The starting point of this project is the literature review and theoretical study. But, these actions are continuous as new information must be gathered from time to time in order to proceed with this project.

After having an overview of the component to include in this project, the suitable components were selected based on the scope and limitation of this project. Hardware implementations begin after the components were available. After that, the whole system was integrated for testing and optimization before the real demo and presentation to the panel of the final year project.

The time frame allocated for this research study is 10 months. It will start in July 2012 and is projected to be completed in May 2013. The Gantt chart for the project and its milestone are shown as in Table 1.

Development of Graphical User Interfacing using LabVIEW for analysis of the Photoplethsmography signal configurations for data centre application will be build to enables the community to visualize the impact and application of the proposed methods in determining the best solutions in designing it with respect to reliability and cost. This project will be presented in the FYP Presentation Day.

PROGRESS 5 : METHODOLOGY

Block diagram

The following is the experimental set up for acquisition of pulse wave. Heart activities are senses from subject through the PPG sensor. PPG signals are taken from individual persons using Biokit at a sample rate of 1000 samples/second. The frequency response for PPG it is 0.05-10Hz. It is obtained by using reflection type PPG sensor, these signal are amplified using a PPG amplifier and are interfaced with the PC using DAQ (NI USB-6009).

 The NI USB-6009 is a USB based data acquisition (DAQ) and control device with analog input and output and digital input and output. The main features of NI USB-6009 are as follows :

·         Analog input (AI): 8 inputs with referenced single ended signal coupling or 4 inputs with differential signal coupling. Software-configurable voltage ranges: ±20V, ±10V, ±5V, ±4V, ±2.5V, ±2V, ±1.25V, ±1V. Max sampling rate is 48kS/s (48000 samples per second). 14 bits AD converter.

·         Digital input (DI) and digital output (DO): 12 channels which can be used as either DI or DO (configured individually). These 12 channels are organized in ports, with Port 0 having lines 0... 7, and Port 1 having lines 0... 3. Input low is between -0.3V and +0.8V. Input high is between 2.0V and +5.8V. Output low is below 0.8V. Output high is above 2V (with open-drain and push-pull as options). (USB-6008 has only open-drain output.)

·          On-board voltage sources (available at individual terminals): 2.5V and 5.0V

·         Power: USB-6009 is powered via the USB cable.

·         Application software: LabVIEW: Windows, Mac, Linux. The present document gives an example of how to use USB-6009 in LabVIEW.

PROJECT RESEARCH AND DEVELOPMENT

PROGRESS 4 : RESEARCH ON GRAPHICAL USER INTERFACING (GUI) IN LABVIEW

I made another study on my project. I was searching the information on the GUI system that will be used in my project system. Here was some information gather in my finding;
--A GUI (usually pronounced GOO-ee) is a graphical (rather than purely textual) user interface to a computer. As you read this, you are looking at the GUI or graphical user interface of your particular Web browser. The term came into existence because the first interactive user interfaces to computers were not graphical; they were text-and-keyboard oriented and usually consisted of commands you had to remember and computer responses that were infamously brief. The command interface of the DOS operating system (which you can still get to from your Windows operating system) is an example of the typical user-computer interface before GUIs arrived. An intermediate step in user interfaces between the command line interface and the GUI was the non-graphical menu-based interface, which let you interact by using a mouse rather than by having to type in keyboard commands. Today's major operating systems provide a graphical user interface. Applications typically use the elements of the GUI that come with the operating system and add their own graphical user interface elements and ideas. A GUI sometimes uses one or more metaphors for objects familiar in real life, such as the desktop, the view through a window, or the physical layout in a building. Elements of a GUI include such things as: windows, pull-down menus, buttons, scroll bars, iconic images, wizards, the mouse, and no doubt many things that haven't been invented yet. With the increasing use of multimedia as part of the GUI, sound, voice, motion video, and virtual reality interfaces seem likely to become part of the GUI for many applications. A system's graphical user interface along with its input devices is sometimes referred to as its "look-and-feel."---
In LabVIEW Software, it use information from a person by using photoplethsmography sensor on fingerprint by using finger probe. The information gathered will be used for matching it with multi-million data bases.

INTRODUCTION

PROGRESS 3: INTRODUCTION

Before I get started with this project, I had done some researches about the Photoplethsmography sensor to get overview for more understanding.

What is Photoplethsmography sensor?

Photoplethysmography (PPG) is a simple and low-cost optical technique that can be used to detect blood volume changes in the microvascular bed of tissue. It is often used non-invasively to make measurements at the skin surface. The PPG waveform comprises a pulsatile ('AC') physiological waveform attributed to cardiac synchronous changes in the blood volume with each heart beat, and is superimposed on a slowly varying ('DC') baseline with various lower frequency components attributed to respiration, sympathetic nervous system activity and thermoregulation.
