Automatic detection of eye movement
Kaňa, Michal ; Švrček, Martin (referee) ; Kolářová, Jana (advisor)
This bachelor thesis deals with possibilities of using computer system Biopac for detection of eye movements. Reader is introduced to problematics of eye movement, method of measuring with the help of electrooculography and computer system Biopac. The goal of this bachelor thesis is to design a procedure of measuring and method of processing of evaluated data. This elaborated method of procedure allows measuring eye movement detection based on the method of Electrooculography and present results of measuring data. Functionality of the method was demonstrated on the results which are also part of the thesis.

Polygraphic measurement of stress
Faltýnková, Květoslava ; Kolář, Radim (referee) ; Bubník, Karel (advisor)
This work deals with polygraphic measurement of stress. The paper describes the physiological manifestations of stress induced as a result of false answers to the question and ways to measure these phenomena. It focuses mainly on changes in heart rate, blood pressure, respiration and skin resistance. It is designed to work in the block diagram of polygraph, described the course of measurement and evaluation. The work is also mention of lie detection using EEG.

Wireless accelerometer modul
Lysoň, Jakub ; Odstrčilík, Jan (referee) ; Bubník, Karel (advisor)
This master’s thesis describes a wireless accelerometer module. The aim of this work was to study the properties and involvement of the accelerometer, wireless module design for data transfering from the accelerometer to the PC and the module implementation. As a wireless device is used bluetooth module that enables communication between the product and the computer. The wireless module used rechargable lithium ion battery that helps keep module alive without adapter or net cable.

Load influence on baroreflex sensitivity
Szöllösi, Tomáš ; Provazník, Ivo (referee) ; Kolářová, Jana (advisor)
The topic of my Bachelor thesis is focused on through acquaintance problems of load influence on baroreflex sensitivity, to creat measuring protocol and implementation of this measurement. In this project, I examined how baroreceptors and then baroreflex work. I also note with physiology of blood circulation, and I examined the different types of measurement baroreceptor sensitivity. I did the measurement by measuring protocol. I evaluated the results using spectral methods and processed in Matlab. Finally, I have different results statistically evaluated using T-test.

Evaluation of upper limb muscle fatigue
Netopil, Ondřej ; Janoušek, Oto (referee) ; Horáková, Pavla (advisor)
This work deals with the evaluation of upper limb muscle fatigue by analyzing the signal of surface electromyography. It briefly describes the human muscle of anatomical and physiological point of view. There is also described a mechanism of symptoms of muscle fatigue. The work devots to electromyography, electromyography signal processing and evaluation of muscle fatigue using electromyography. The aim is to evaluate muscle fatigue in trained and untrained person depending on gender and depending on the size of the load, which is proportional to each volunteer separately. The measurement is performed on twelve young volunteers. For measurement is used the Biopac system. The magnitude is determined using a dynamometer. The results of this work show that the most tired are untrained men, then untrained women, then trained men and at least tired are the trained women.

Controlling of myoelectric prothesis
Tomanová, Markéta ; Bubník, Karel (referee) ; Janoušek, Oto (advisor)
The Master´s thesis summarizes the knowledge about controlling of myoelectric prostheses. The Introduction part of this work provides an overview of the anatomy of muscles and their contraction. In case of restricted function of hand, it is necessary to compensate this deficiency by using prosthetic limbs. Among one of the most technically difficult is robotic prosthesis. In this semestral work is myoelectric prosthesis replaced by a robotic arm. Arm is controlled by the electromyographic signals. The signals are recorded by Biopac acquision unit, then processed in LabVIEW and robotic system is controlled by the Arduino platform.

ECG measurement using BIOPAC system
Kotek, Lukáš ; Rozman, Jiří (referee) ; Balogh, Jaroslav (advisor)
The main aim of this bachelor project is to acquainted with BIOPAC system and with the theory of electrocardiography. After investigation of possibilities to retrieve analog and digital data as well as measurement of ECG signal was developed circuit enable to convert analog signals to digital and then export digital signal via USB to the PC. Developed circuit is based on integrated circuits ATmega8 a FT232RL. Visual Studio was used to create application for registration and calculation power spectrum ECG signal in C#.

Analysis of measured parameters of the cardiovascular system
Lysoň, Jakub ; Vítek, Martin (referee) ; Kratochvíla, Jiří (advisor)
This bachelor thesis talks about the measurement of heart electrical activity by twelve lead ECG. The diagnostic system Biopac is used for measurement, featured by the computer program Acqknowledge. The own authentic method is designed to detect effect of load on increasing in blood pressure and heartbeat. Using a statistical procedure for testing hypotheses in this area the measurement results will be evaluated. For the analysis of measured data in time and frequency domain was used program Matlab, in which the measured results were imported. It was created functions that are implemented in an medium of Guide to the graphic design program.

Evaluation of electrical axis of the heart
Temelová, Kristýna ; Vítek, Martin (referee) ; Janoušek, Oto (advisor)
This bachelor's thesis describes the issue of electrocardiography focusing on the methodology of automatic evaluation of heart's electrical axis. Part of this work is a description of an application created in Matlab which enables to plot the tilt of the cardiac axis. The cardiac axis is evaluated in terms of its dependence on the examined person's position. This bachelor's thesis includes a database of ECG signals of twelve volunteers measured in various positions (supine, sitting, tilted), obtained using the Biopac system, accompanied by video documentation. The created application serves both the data analysis from the database and other experimental signals. A guide for students performing practical exercises is included.

ECG Biofeedback
Macková, Pavlína ; Kolářová, Jana (referee) ; Sekora, Jiří (advisor)
The master’s thesis is focused on the possibilities of measuring heart rate of ECG signal and its use in therapeutic game of ECG biofeedback. This thesis describes the way of measuring ECG with acquisition unit Biopac and analyzes signal processing for measurement of heart rate – algorithms of QRS detection, HRV analysis. Realisation of therapeutic is designed for applications in Matlab.
