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.

Wireless sports timer
Gál, Marek ; Horák, Karel (referee) ; Petyovský, Petr (advisor)
This work deals with design and realization of universal sport timer and uses wireless communication between individual components. The purposes is to achieve maximum mobility, reliability and simplicity for users. This work doesn‘t deal with sensing elements of measuring system, it only provides examples of their typical usage. The content of this proposal is the primary unit, which will ensure time measurement with 0,01s resolution and the secondary unit, which will track a sensing elements and provide information for processing to primary unit. The design comprises communication method, hardware of all devices and firmware.

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

Adjustable timer for three-phase motor
Motyčka, Lukáš ; Petržela, Jiří (referee) ; Hruboš, Zdeněk (advisor)
The thesis describes several potential solutions of an adjustable timer, such as monostable multivibrators, asynchronous (ripple) and synchronous counters and microcontrollers. It also deals with issue of switching three-phase asynchronous motors with limit a high starting current on starting - star-delta switch, softstarter, frequency inverter. Particular attention is focused on the conceptual design of the timer using micro- controller Atmel (timer control unit), LCD (display device) and control switches. The microcontroller will be complemented by external 32,768 kHz watch crystal, necessary for real-time function - Real Time Counter (RTC). The cause for this choice is not only simplicity and clarity of control to the operator, but also reliability, low power consumption and also the price of the device itself.
