Using the ADAM industrial sensor system in laboratory measurement
Nos, Pavel ; Chmelař, Milan (referee) ; Rampl, Ivan (advisor)
Main task of the Master Thesis is to introduce into sensor systems used in the field. On Advantech sensor system with use of ADAM 4000 modules is shown decentralized sensor system which comunicates over RS 485 and using master computer. Within Master Thesis was compiled measuring board and were assembled three programs which demonstrate possible use of different types of modules. Main development environment is used ADAMView. Each modules has different number and types of inputs and outputs. Using of sensor system saving measurement time, increasing measurement effeciency, relieves data processing and automatize measurement.

Electronic thermometer and humidity meter
Lapáček, Petr ; Chmelař, Milan (referee) ; Lattenberg, Ivo (advisor)
This master´s thesis deals with the design of measuring station used for the temperature and humidity measurement. There is a theoretical basical description of sensores for temperature and humidity measurement in the first part. Furthermore I deal with a theoretical design of measuring system, especially with types of materials and possibilities of communication between these parts. The main part of thesis is about communication on buses I2C,UART, SPI, RS485. There is a description of function procedure of particular integrated circuit, moduluses which are used in task in the next part of thesis.In the practical part I was engaged in a functional design of autonomous system for the temperature and ralative humidity measurement. Data could be presented by the computer after connection with the station. There is a description of testing the particular circuits and the full description of function particular blocks of system in the task. I have used the program called Eagle for schemes and printed wirings designing. The copy is placed on CD ready for next using. In the last part of thesis is a brief description of program algorithm "Meteostanice", which I have created for data presentation. There is an illustration of measuring results in these last part. The task is completely ready for the realization of autonomous system of weather station with its own memory.

Four-electrode impedance plethysmograph
Port, Martin ; Kolář, Radim (referee) ; Chmelař, Milan (advisor)
This master’s thesis is an introduction to the measurement of changes in tissue impedance of blood flow by impedance plethysmography. Other chapters deal with the kinds of plethysmographs and their principles. The aim is to draft four-electrode impedance plethysmograph to measure changes in tissue impedance depending on blood flow. First, describe the individual blocks of the medical instrument. The practical part of the master’s thesis involves circuit design four-electrode plethysmograph. Given that a very important role in its function plays a constant current source operating at a frequency of 60kHz, this subset was implemented and verified its correct function. To draw component schemes used program EAGLE version 5.10.0.

Alpha monitor
Svobodová, Eva ; Kolářová, Jana (referee) ; Chmelař, Milan (advisor)
The master´s thesis presents the problems of EEG biofeedback and its application to relax people. The first part discusses the properties of EEG signal , the requirements of the standard EEG and also distribusion signal into different frequency bands. The main essence of the work is the design and realization of Alfa Monitor – a device for relaxation , that for implamanting EEG biofeedback uses acoustic form and sensing of electrical activity of brain in the region of alpha waves. The second half of the work is t focused on circuit design, using integrated circuits with component values of relevant calculations . Further, it analyzes the practical implementation of alfa monitor. The last chapter is devoted to the testing the functionality of this device.

Heart rate measurement
Jiřík, Ondřej ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
This work deals with the measurement of heart rate parameters. One of the objectives of this work is a summary of methods for measuring heart rate, from which data can be derived heart rate and subsequently evaluated. Also deals with the accuracy of this parameter. It describes the basic characteristics of sensors and applicable in terms of sensitivity to movement. In the work is drawn design of a simple heart rate monitor with a range of 40-200 beats per minute. For the whole device is carried out by the proposal of the printed circuit board in EAGLE program.

Respiratory rate measurement
Maršálková, Leona ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
This bachelor’s thesis deals with possible ways of measuring respiratory rate. It focuses on the description of the structure of device used to measure respiratory rate, including sensors, which are used for this purpose. In conclusion of theoretical part is mentioned the possibility of using respiratory rate measurement in medicine. This thesis also contains a description of respiratory rate sensor design using a thermistor sensor and implementation of virtual meter respiratory rate in LabView. The last part of this thesis deals with the evaluation results and practical application of this sensor.

Electrotherapy
Fernandová, Dominika ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
This bachelor's thesis deals with the methods of physiatric treatment and realization of a generator and a device for electrotherapy. In the first part, electrotherapy is analyzed in detail and other methods are mentioned only briefly (they are listed here for completeness). When analyzing electrotherapy main attention was paid to electrical currents that are mainly used. Diagnoses for which electrotherapy is suitable are also mentioned. The second part of this thesis deals with designing a generator in LabView software and designing and implementing a device for electrotherapy.

Uninterruble Power Supply (UPS)
Suchý, Petr ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
My Bachelor's thesis deals with the question of Uninterruptible Power Supply (UPS). Continual power supply is required in many branches of the industry at the present time. It is very important to provide for question of UPS and it is necessary to evolve that. My qualified work refers to singular types of back-up power supplies, their possibilities and places of application. The work includes the proposal of block scheme for monitor located in the ward of intensive care, defined requires for each type of blocks and proposal of automatic packaging battery with 50Ah capacity.
