Breath monitoring during motion therapy
Koťová, Markéta ; Bubník, Karel (referee) ; Kolářová, Jana (advisor)
This semestral thesis deals with continuous monitoring of pulmonary ventilation during the patients' theraphy and focuses especially on monitoring of their ventilation processes. It is necessarry to detect, monitor and differentiate abdominal and thoracic breathing during the theraphy. This thesis describes the very basic and common method, a spirometry. Next, an overview of more advanced state-of-the-art methods based on both, tactile and proximity principles is given. In addition to that, two recently developed methods by BUT are discussed as well -- a tactile-based measurement similar to blood pressure sensor and a proximity-based measurement method employing TOF cameras. The data acquired by these two methods are proccesed and examined in order to evaluate and justify their performance in a real application.

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.

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.

Robotic hand control by myopotentials
Jablonská, Dominika ; Janoušek, Oto (referee) ; Bubník, Karel (advisor)
The thesis deals with the measurement of myopotecials and their using in controlling the robotic arm. First, it is theoretically described electromyographic signal, his scanning and subsequent processing. There is also described an arm which it is used here. The next aim of this project is paying attention scanning signal on human hands using Biopac system and signal processing in MATLAB with Robotic Toolbox. Also was created a computer model in the user interface GUI.

Doppler blood flow indicator
Böhm, Richard ; Bubník, Karel (referee) ; Rozman, Jiří (advisor)
This bachelor‘s thesis deals with literature search of basis of ultrasonic and Doppler methods of measuring blood flow velocity. It also deals with the evaluation of Doppler signals and with the individual functional system blocks, with the indicator of blood flow with the operating frequency of 4 MHz, with the generated ultrasonic intensity of 100 mW/cm2 and with the average transmitting changer in shape of D = 8 mm. Furthermore, experimental verification of individual system components is included.

EKG Simulator
Šebesta, Patrik ; Sekora, Jiří (referee) ; Bubník, Karel (advisor)
This bachelor work deals with the implementation of autonomous ECG simulator output with a single microprocessor, alphanumeric display, control buttons and matching circuits using a simulator which can be connected to the ECG device. The simulator allows you to set the heart rate and select the number of samples generated in a row.

Automated Detection of graphic elements in EEG signal
Jančová, Ivana ; Ronzhina, Marina (referee) ; Bubník, Karel (advisor)
This thesis deals with the analysis of EEG, namely detection of graphic elements. The aim of the thesis is to describe methods suitable for detection of graphic elements and implementation of the two methods in MATLAB. The first part of the thesis describes the basics rhythms, artifacts and epileptiform transients occurring in the EEG. The second part deals with the methods of detection and their mutual comparison. The discussed methods are spectral analysis, correlation analysis, wavelet transform, cluster analysis and matched filter. Other parts of the thesis describe the database PhysioBank and implementation of the correlation analysis and matched filter. In the last part is the comparison of the success of selected methods and comparison is done by calculating sensitivity and positive predictive value.

Electromyography
Svobodová, Eva ; Bubník, Karel (referee) ; Chmelař, Milan (advisor)
The first part of this bachelor´s thesis is focused to elements of the muscle and nerve structures and spreading of excitation (signal) through them. Second part is concerned to electromyography as an investigative method that is used in medical diagnostics and basic requirements for the electromyography and its components. In this thesis is described examinational techniques motoric and sensitive nerve conduction. There are described requirements of recording, stimulation and also evaluation of constituent elements of signal. The final part is focused on specific laboratory exercises with specific instructions.

Modul for electrical stimulation
Lahodný, Libor ; Balogh, Jaroslav (referee) ; Bubník, Karel (advisor)
Bachelor’s thesis is concerned with the concept and building of the stimulator which is controlled using a computer USB port. The introduction discussed the issue of DC/DC converters and their possible variations. In the next section of the introduction describes the components used in the stimulator and the Arduino development kit whereby the further stimulator is controlled. This stimulator makes possible to change voltage, current, frequency and pulse width.Overload protection is realized with the aid of electronic fuse and using software.
