Detector of bubbles in blood
Foltýn, Vojtěch ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
ABSTRAKT This thesis is the theoretical part deals with various ways of cleansing the blood, with a focus on hem dialysis. Describes the technical solution and monitor the dialysis flow diagram of blood and dialysate. The paper describes various solutions to detect bubbles in the blood and their advantages and disadvantages. Based on the best method of detection are designed detector bubbles. Working in the practical part contains a proposal detector set for venous diameter of 20 mm. Equipment to detect bubbles allows for connection to a blood pump discontinue its activities. Output works are drawing diagrams, printed circuit board design and implementation of graphs circuits.

Device for measuring of the reaction time
Bohuš, Michal ; Kolářová, Jana (referee) ; Balogh, Jaroslav (advisor)
The aim of this bachelor thesis was become acquainted with human reaction time,its measurements and use. Part of the project was to build a device that measures reaction time of audio-visual stimulus. The device consists of stimulating and controlling parts. Audio-visual stimuli are scanned and controlled by microcontroler ATmega 16. Based on the obtained reaction time evaluate reaction time of measured entity.

Timer For RC Models
Fišer, Ondřej ; Pospíšil, Martin (referee) ; Šebesta, Jiří (advisor)
This paper describes complete design of timer for RC models. Described timer has three PWM outputs. With these outputs it is possible to connect two independent servo-motors and engine controller. 1 signal. The whole is controlled by 8-bit microprocessor. The time records are stored in external EEPROM, that can be programmed using I2C. Paper further discuss design of programming, which can be easily programmed the memory of EEPROM by the PC or smartphone. The goal of this paper is to design and build high quality RC timer with accessories.

Table tennis robot
Nguyen, Thuc Tuyen ; Věchet, Stanislav (referee) ; Marada, Tomáš (advisor)
This diploma thesis deals with designing and manipulating a robot for training table tennis. Robot's mechanical construction is based on aluminium profiles supported by various standardized assembly units, such as rotating bearings, plain bearings, threaded rods... The front-end part of the robot, which requires better deformation property and lighter weight, was made from ABS material using 3D rapid prototyping technology. The design of the robot allows its body to rotate around three axises. Thanks to the high dynamical ability, robot can be set to throw balls to various places on the playing table, with different types of ball spin. Balls will be shot out by two rubber wheels, which are attached to two electrical DC motors. By driving the speed of the two motors, we can control the speed of the ball, as well as speed of its spin. All robot's activities are driven by an embedded system designed using microcontroller ATMega128. A firmware for controlling robot's function was writen and flashed into the microcontroller. End-users might communicate with the robot via a system of buttons and a text LCD display. The built robot was tested and it has shown its ability to throw balls to 6 different places of the playing table, at different speeds, with different types of ball spin, and different spin speed, according to the parameters set by user.

Alarm device
Demjanics, Ferenc ; Drexler, Petr (referee) ; Szabó, Zoltán (advisor)
Timer is an equipment that allows us to provide time measure. There are in all-day use a plenty of timers, but their use is ussually limited for one purpose only. Because of this I decided to compile a timer which allows to apply it for an individual needs. This granted a wider spectre of use in real life. We used a microcontroller from Atmel, and also a DCF77 signal (atomic time signal)receiver and decoder. Further, we required a real-time circuit, DC/DC converter, and a powerswitch from manufacturers STmicroelectronics, and Linear Technology,respectively.For the imaging unit we used a graphic LCD connected via an I2C bus, which is commercially available spare part for mobile phones. Following the design we compiled and revived a hardware part of the device. After a succesfull revive, we gradually compiled a program for microcontroller. The program defines a processes for run of the device. It was written in programming language C, with use of compiling enviroment avr studio 4

Physics Simulation for Pinball Game
Čermák, Jakub ; Polok, Lukáš (referee) ; Zachariáš, Michal (advisor)
The objective of this work is to create a library for physical simulation and using the library to create a game of pinball, on which you can test functionality of the library. Problems that appeared during the creation of the library, are described in this paper along with their solutions. In particular, tunneling, detection and results of collisions. Subsequent optimization solutions to these problems for our specific library. Of no smaller importance are principles which reduce the requirements of the final simulation. Among the most important ones are the correct choice of limits, detection of rolling and sleep of slowly moving dynamic objects.

Návrh automatizovaného systému pro zavlažování zahrady
Vaněk, Jakub
This work introduces the issue of automatic irrigation. It also provides a brief overview of currently offered commercial solutions and a description of their advantages and disadvantages. The main part of the thesis describes the design and procedure for the realization of the own irrigation system, a detailed introduction to the finished system, the course of its testing in laboratory conditions and, finally, its comparison with commercially available competition.
