Artificial aorta for activity demonstration of intraaortal baloon contrapulsation
Bičiště, Jan ; Rampl, Ivan (referee) ; Zeman, Václav (advisor)
This dissertation work describes design and construction of simulated aorta device intended to demonstrate performance of the intra-aortal balloon catheter (IAB), and to test reaction of the contra-pulsation pump during simulated cardiac output in conditions of tachycardia, bradycardia and arrhythmia. The major part of the device is transparent plastic tube. The pressure pulses (waves) are generated inside this plastic tube to simulate real cardiac output. These pressure pulses are generated by step motor with membrane. The step motor is controlled by programmable control system AMiNi-E. Individual pressure pulses simulate cardiac output in conditions of tachycardia, bradycardia and arrhythmia. Required simulated cardiac output is selected by control switches. Generated pressure pulses are read by pressure sensor and are transferred to the control system of the configuration computer. Read data can be displayed as graphs in program Microsoft Excel. The intra-aortal balloon catheter (IAB) is inserted inside the aorta and is connected with contra-pulsation pump which on pressure pulse is responding.

Thin device for the real temperature distribution measurement with the negastore matrix
Martinásek, Zdeněk ; Chmelař, Milan (referee) ; Rampl, Ivan (advisor)
The main task of the Master Thesis is to project a device to measure surface temperature distribution by matrix of diodes. The maeasuring device is designed for usage at places where other thermal map scanning measuring methods (e.g. thermocamera) can not be used. The key objective was to design an appropriate measuring method for selected type of sensor. This method should ensure the most effective detection of the changing value, translate received values to the digital form and send it to the computer. All circuits were powered over USB (Universal Serial Bus) together with the signalling. Calibration was needed due to different sensors technical parameters. The calibration was realized on the software level and displayed with the thermal map scanning on the computer. The final project has the form of the measuring installation with 256 sensors on 8x8 cm area.

The simulation of biometric protection systems working on the face recognition principle
Dubský, Milan ; Rampl, Ivan (referee) ; Atassi, Hicham (advisor)
The aim of this work is to realize a system in the Matlab-Simulink environment, which will be able to detect and recognize the human face from the input image. The created model will actually simulate the biometric security systems working on the principle of face recognition. The work is divided into two parts. In the first part, several methods for face detection from image are described. We focused on the symptomatic oriented and color segmentation methods. The pattern matching method is also described and implemented; the advantage ofthe pattern matching that it can be used either for face detection or face recognition. The second part of this work contains a description of the face recognition. Where PCA (Principal Component Analysis) are used for this task, this part of the work also includes experimental results of tests performed on our methods.

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.

Communication system for the blind - the mobile part
Dadák, Jiří ; Rampl, Ivan (referee) ; Herman, Ivo (advisor)
Orientation in big administration buildings can be very difficult for visually impaired people. Although most of the buildings are equipped with elevators, the buttons of which are designated with Braille characters and acoustic signals, it might be very difficult for the visually impaired to actually find the particular office. Even if there were descriptions in Braille at each office door, it would prove very complicating for the visually impaired individual to localize the descriptions in the first place, especially in case of a large number of offices in the building. That may also concern other important places, such as toilets, inside a building. In this thesis, I am going to present a design proposal of a communication system which uses transceivers placed at significant points in a building and receivers placed at the end of the white cane for orientation inside a building.

External pacemaker
Lank, Petr ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
This master´s thesis deals with the problem of heart stimulation by using external pacemaker. Such external pacemaker is used for a short – time stimulation of patient to overcome the time before the implantation of such apparatus. The master´s thesis informs about the basic function of heart and possible heart disorders which are treated by pacemaker. Great deal of master´s thesis is devoted to the design of external pacemaker wiring. This section describes the possibilities of controlling the pacemaker, circuits for detection R-R interval, a design of output circuit eith regard to required of stimulation and pacemaker feeding. The program Pspice was used to check the functional appropriateness of designed circuits and it was successively simulated in a non - soldering field.

The first aid system controlled by computer
Příhoda, Vratislav ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
Human life is too precious to be lost. The rules of the first aid are not complicated. The knowledge of resuscitation is the basic principle of the first aid. You don't need only theoretical knowledge to do the right resuscitation. It is necessary to have a some practical experience. The experience of resuscitation is possible to get on a tutorial trainer manikin. This work considers a concept of system for analysing training of resuscitation by using computer. The first part of this thesis describes the right process of resuscitation by guidelines of European Resuscitation Council for Resuscitation 2005. The other part deals with possible ways of monitoring the correct procedure of instant resuscitation and the most common mistakes made by trainees during the training, are described in the following parts of this work. Component part of this thesis is summary of available resuscitation models. Last part is dedicated to the design of hardware and software for rating quality of resuscitation process. Resuscitation trainer manikin AmbuMAN from the company Ambu was also used. Among others contains "first aid" test as well.

ECG generator for equipment testing
Čech, Petr ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
This diploma thesis is focused on testing ECG monitors and ECG instruments. There are discussed origin and charakteristics of ECG signal. The ECG signal is presented by standard leads. This is the reason, why the way of making leads is mentioned. One chapter is aimed at generating ECG signal. There are set requierements for the ECG generator. These requierements results from ECG instrument possibilities and from ECG signal character. Next part of this diploma thesis includes hardware design of each part of the system. The system was designed with respect to mobility and 12-leads systems compatibility. Finaly the thesis includes design of the controll software.
