HVAC unit for optical head
Janošík, Tomáš ; Šotner, Roman (referee) ; Kincl, Zdeněk (advisor)
This thesis deals with the design of a HVAC unit for temperature regulation inside an optical head. The unit is completed by functions which optimize its reliability such as checking of fan, heating element, monitoring a supply voltage and saving operating information into the memory. The device communicates with PC via serial interface RS-485. There is also described the possibility to switch the unit to a manual mode, in which the temperature interval is setting by a potentiometers. Solution of this thesis is function prototype.

Altitmeter for RC aircraft models
Kotulek, Milan ; Štohanzl, Milan (referee) ; Prokopec, Jan (advisor)
Bachelor thesis describes a device for measuring and recording flight position RC model, which consist of a microcontroller and a pressure sensor. It measures values of atmosferic pressure and these data are convert by microcontroller to specific height. All is during flight saved to memory and later can be transferred to PC.

Processing of the RC plane model telemetry
Žák, Tomáš ; Fedra, Zbyněk (referee) ; Prokopec, Jan (advisor)
Bachelor’s project focuses on problematic about scanning state of RC plane model, during the fly. In detail there is described internal and external structure, including communication. Main objective of work is design functional board for scanning state of RC plane model, during the fly. There is used akcelerometer for scanning actual state of plane. Accelerometer sends measured data in digital form to microcontroller for evaluating. List of used components is in the enclosure.

Environment control with microcontroller
Králíček, Martin ; Šebesta, Jiří (referee) ; Fedra, Zbyněk (advisor)
This bachelor project focuses on equipment for environment management and check with help of microcontroller. This equipment should enable us to check and manage home environment for example for goldfish, hamsters, spiders and other small pets. Further on, this project describes individual parts of equipment which the ECM-01 consists of. ECM-01 is consists of general block, feed block, relay block with power supply and sensors. The ECM-01 consists of several functional blocks which are controlled by the main microcontroller. The functional blocks contain measurement transducers and action units. The choice of blocks depends both on individual environment and the user. The user can choose which values he needs to control and measure.

Radio Telemetry for RC Aircrafts
Žák, Tomáš ; Fuchs,, Michal (referee) ; Povalač, Aleš (advisor)
Master‘s thesis is focused on problematic about state of RC plane model during the flight. Device is able to measure overload, height, position, pressure and velocity of the flight and store this measurement data to memory medium. The main aim of the master‘s thesis was to design a functional board, firmware for device and design simple program for evaluating of measured data. Involvement consists of five basic parts. First part is microcontroller, which processes measurement data and communicate with others parts. Next is accelerometer. Accelerometer is used for scanning overload of the plane. Barometer is used for measurement of height and pressure. For measuring position and velocity is used GPS module. Last part is memory medium. MicroSD is used as memory medium for storing measurement data. Evaluation of measured data is realized as simple program with base graphical user interface. Program was created in Matlab.

Communication assembly for optical cableless linking
Kapuš, Martin ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
This Graduate Thesis is about communication module for optical wireless network. This device read data from RS232 port and two analog inputs and sends it through internet to a remote Computer. Furthermore allows voice communication between local user on module and user on remote computer. Device allows communication with standard headphones and microphone, or with Bluetooth handsfree. Basic part is microprocessor MCF5223 and Bluetooth Ezurio BISM II module. Control program has been written in C language. Printed circuit is created by EAGLE program. This device is managed via web interface and settings have been stored into EEPROM memory. Work contains description of separately parts and blocks, source code of program, description of source code and printed circuit designs.

RFID equipped security terminal
Vařečka, Radek ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
The concept proposal of the RFID security terminal is described in this Master Thesis. The RFID identification and its usage are analyzed at first. The description of the selected fitting circuits, communication bus as well as its parameters follows. The practical realization, proposed module design and designed printed circuit board is described afterwards. Several problems found during activation phase are analyzed in the chapter describing the practical module realization. The problem resolution is mentioned as well. The practical prove of the real module parameters and differences compared to the designed values are described at the end of this Master Thesis.

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.
