Objective of the Master Thesis was to bring in two solutions of miniature PC display. One of them uses the VGA signal as the source of the data. The second uses USB for communication. Display using USB was chosen to be produced. Device contains LCD screen, SD card reader and audio DAC with mini speaker. Software running on the PC allows user to watch part of the screen of the computer. Position and size of the chosen part may be varied. The display may be controlled by touch screen. One part of the software running on PC is a simple video player.

Bakgrund: Diabetes mellitus är en folksjukdom som förekommer på nationell och internationell nivå. Patienter kan lära sig hantera sin sjukdom med hjälp av tekniken som finns idag. Flash glucose monitor (FGM) är en glukosmätare som visar sockerhalten i vävnaden genom en vit rund sensor som sitter på armen. Patienter med diabetes typ 1 och typ 2 kan använda FGM vilket underlättar kontroller av glukosnivåer. Syfte: Syftet med studien var att undersöka hur patienter med Diabetes mellitus typ 1 och typ 2 upplever användningen av glukosmätaren Flash glucose monitor. Metod: En allmän litteraturstudie bestående av åtta utvalda vetenskapliga artiklar från databaserna CINAHL och PUBMED. Granskning av artiklarnas kvalité och analys genomfördes. Resultat: Analysen resulterade i två huvudkategorier, Positiva upplevelser av FGM samt Negativa upplevelser av FGM. Huvudkategorin Positiva upplevelser av FGM delades in i fyra underkategorier som benämns FGMs påverkan på patienters livskvalité, Hantering av FGM, Förbättrad glukosmonitorering samt Ökad kunskap. Majoriteten av patienterna upplevde mer positiva upplevelser än negativa under användning av FGM. Slutsats: FGM upplevdes som lätthanterlig samt ansågs mindre smärtsam. Patienter kontrollerade glukosnivåer mer ofta med FGM och erhöll en bättre kunskap kring sin sjukdom.

This study investigates the learning experiences of three L2 learners of English in connection to the massive multiplayer online role playing game (MMORPG) World of Warcraft (WoW). The participants, who all attend the course English A at upper secondary school at the time of the study, are frequent players of the game.By writing journals, the participants were asked to report on their learning experiences in direct connection to playing the game. In addition to this they were also interviewed in order to gain a further understanding of their linguistic development through the game.The research shows that the participants were very positive to the learning experiences attached to the game. They all had an abundance of examples to show for their linguistic skills improving significantly by playing the game. Especially the opportunity to engage in authentic dialogue with co-players in English reportedly greatly improved their linguistic skills. However, some doubts exist as to the teaching benefits of the game as most participants were negative to using the game in a setting of instructed learning.

An ECG (electrocardiogram) simulator is an electronic tool that plays an essential role in the testing, design, and development of ECG monitors and other ECG equipment. Principally an ECG simulator provides ECG monitors with an electrical signal that emulates the human heart's electrical signal so that the monitor can be tested for reliability and important diagnostic capabilities. However, the current portable commercially available ECG simulators are lacking in their ability to fully test ECG monitors. Specifically, the portable simulators presently on the market do not produce authentic ECG signals but rather they endeavor to create the ECG signals mathematically. They even attempt to mathematically create arrhythmias (irregular heartbeats of which there are many different types). Arrhythmia detection is an important capability for any modern ECG monitor because arrhythmias are often the critical link to the diagnosis of heart conditions or cardiovascular disease. The focus of this thesis is the design and implementation of a portable ECG simulator. The important innovation of this prototype simulator is that it will not create its ECG signals mathematically, but rather it will store ECG data files on a memory module and use this data to produce an authentic ECG signal. The data files will consist of different types of ECG signals including different types of arrhythmias. The data files are obtained via the internet and require formatting and storing onto a memory chip. These files are then processed by a digital to analog converter and output on a four lead network to produce an authentic ECG signal. The system is built around the ultra-low power Texas Instruments MSP430 microcontroller.

Infant apnea is a widespread condition in which infants fail to effectively breathe, and can lead to death. Clinical solutions exist for continuous monitoring of respirations in a hospital setting and requiring constant skin contact. This thesis investigates the construction of a proof of concept device that performs in-home monitoring without skin contact and with commonly available off-the-shelf components. The device constructed used a directional microphone to detect breathing sounds, an omnidirectional microphone to detect ambient noise as a baseline to help isolate the breathing sounds, and LabVIEW software deployed on an inexpensive laptop computer to quantify incidents of apparent lapses in breathing meeting the clinical definition of apnea. Testing results indicate that these components are effective in capturing these events in pre-term infants as well as adults, which provides promising evidence that a low-cost system could be manufactured for home detection to assist in infant monitoring.

A low cost Heart Beat Monitoring device (HBMD) for detecting heart beat in beats per minute is presented in this thesis. An optical technique called “Photoplethysmography” is utilized by attaching to the base of the finger for monitoring beat to beat pulsation. Two major design issues addressed in this research is to achieve a strong and accurate PPG signal and simultaneously minimizing physiological artefacts and interference. In order to achieve the aim and objectives of the research, this thesis thoroughly explores two new signal conditioning hardware designs. Firstly is the design and fabrication of a low cost reflectance mode PPG heart monitor using parallel port interfacing and secondly are the design and development of a portable transmission mode PPG heart monitor using microcontroller PIC16F84A and PIC16F87. Both PPG heart monitor design is divided into three phases. First is the detection of weak pulses through the fingertip. The PPG signal is then amplified, filtered and digitized by the signal processing unit. Finally the heart rate is calculated, analyzed and displayed on the computer using parallel port interface and on the liquid crystal display using microcontroller PIC16F87. A comprehensive circuit design and analysis work was implemented verified by Proteus VSM circuit simulations and laboratory experiments. Data is presented from the method comparison study in which heart rates measured with the reflectance mode PPG and portable transmission mode PPG heart monitor were compared with those measured with standard techniques on 13 human subjects. Benchmarking tests with approved pulse oximeter and blood pressure monitor Omron M6 reveals that the PPG heart monitor is comparable to those devices in displaying the heart rate. It is also verified through experiments that both PPG heart monitor design fulfill the objectives, including achieving strong and accurate PPG signal, reduction in physiological artefacts and interference and financially low in cost. As the conclusion, the current version of the reflectance mode PPG and portable transmission mode PPG heart monitor successfully measure heart rates fast and reliably in most subjects in different body position. The PPG heart monitor proposed avoid the need to apply electrodes or other sensors in the correct position which directly minimizes the preparation time drastically. This makes the PPG heart monitor more attractive for heart monitoring purpose and its advantage should be explored further. / Ministry of Higher Education Malaysia (MOHE) and Universiti Tun Hussein Onn Malaysia (UTHM)
