The controlled heating of composites materials
Fajkus, Martin ; Havlíček, Tomáš (referee) ; Šteffan, Pavel (advisor)
Expected work solves problem of controlled heating of composite material for outdoor application. Basement of work is analysis of submitted concrete specimen of composite. Then I find out influence of direct and alternating voltage on submitted specimen and I choose method of measurement. Whereas I chose correct method of measurement, I could measure all specimens. From comparing I chose specimen of composite material, which are suitable for a next application. For chosen specimen of composite material I designed control unit for heating and tempering. The control unit was designed according to their parameter.

The open mobile phone platform
Malinčík, Ondrej ; Šteffan, Pavel (referee) ; Macháň, Ladislav (advisor)
The aim of this work is construction of mobile phone which can be build using com- ponents that are widely available. The concept allows control of mobile communication in GSM network on AT commands level. Energy saving is emphasised and alternative power source using solar cell is examined. Manufacturing data and docummentation is available for user.

The system for administration keys trough the using RFID
Veselý, Aleš ; Šteffan, Pavel (referee) ; Pavelka, Ondřej (advisor)
This thesis dealing with description and system design for administration keys trough the using RFID technology. The main task of this thesis is create a complete controlling algorithms for this system include operating program for platform Windows. Practically output of this thesis is system controlled by microcontroller, which make a decision based on authorisation whether man in question have an accession to the system and which keys he can take.

Wireless controlled car model
Závodný, Vilém ; Škorpil, Vladislav (referee) ; Šteffan, Pavel (advisor)
The work deals with the analysis and practical implementation of advanced features in cars, which are responsible for greater passenger comfort and greater security for both passengers and other road users. All the work is solved on a remote-controlled model car, hence the need to deal not only with modern elements in cars, but also wireless data transmission, motor control, reliability of the system and a number of component problems. All these problems that occurred during work and their solutions are described in the following document. The work was based on the introduction of new items, modules and components that can be deployed as sensors, evaluation items, and other electrical and software components for the automotive industry in connection with electrical engineering and telecommuni- cations technology. Further work is focused on efficient wireless control of the vehicle, measuring environmental conditions and processing data so that they can be sent as soon as possible to the host PC or respond to them directly in the microcontroller in case of critical values.

Numeric keyboard
Hladký, Pavel ; Novák, Lukáš (referee) ; Šteffan, Pavel (advisor)
This thesis deals with design of numeric keyboard, which can be connected to personal computer or laptop through USB interface. This numeric keyboard can be also configured using application for operating system Windows. Backlight pattern generator is also part of this application. Theoretic part deals with various types of keyboards, switches and closer description of USB interface. Practical part deals with sole design of circuit that detects keystrokes and sends information about active switches through USB, description of used components, description of microcontroller service routine and description of the application for backlight pattern generating. At the end of this thesis are described results of measurements which were made to choose mechanical switches with shortest debounce time and keyboard response to key press.
