TV Remote Controller
Bordács, Balázs ; Hála, Ondřej (referee) ; Hermany, Jiří (advisor)
This master’s thesis deals with parameters of the TV Remote Controller. Aim of this work is studying standards of remote controling of TV receiver by the way of infra-red light. For succesful solving of this project is important to learn about the theory of IrDA. In the second part ot this thesis is designed measurement unit for measuring the parameters of the remote control. The measurement unit includes an integrated IR receiver and photodiode for receive IR signals from remote control. The description of measurement unit blocks and principles of measuring parameters are also placed there. The final part is devoted to processing the measurement results of measuring levels and time waveforms of signal in the receiver module, directional characteristics of remote control and receiver. For measuremented unit is created laboratory task including the role specification and protocol.

Computer Remote Control Using Cell Phone
Řeháček, Prokop ; Jaroš, Jiří (referee) ; Pospíchal, Petr (advisor)
This thesis deals with the creation of remote control application using Bluetooth wireless technology. The work introduces a modern Android operating system and software development for this system. Application of remote control consists of parts: client for Android OS and server for GNU/Linux. The client was implemented in Java and the server has been created using the Qt toolkit and C++. Software development is divided into parts: design, implementation and testing. The result of this thesis is software that can control multimedia programs for audio and video files.

Keeloq System Experiments
Kočíř, Michal ; Hajný, Jan (referee) ; Strašil, Ivo (advisor)
The bachelor thesis deals with security issues in wireless control. On this basis the laboratory task for experiments with Keeloq system is designed. The concept of laboratory task is justified and supplemented by processed documentation. In the first part of this thesis the principles of security and transfer of information for wireless technology are described. In the second part KeeLoq system is analysed. There are the principles of encoding and decoding of transmission of KeeLoq system telegrams described. KeeLoq 3 Development Kit of Microchip company is used for description of encoding and decoding. The next section deals with an attack on KeeLoq system by "brutal force", which is also demonstrated by generated code in programming language C. The third part provides the concept of laboratory tasks that includes introductory meditation, discussion on assigned elements, content and structure of laboratory task. Finally, the fourth part contains the documentation of lab experiments with KeeLoq system, whereby students work out laboratory task.

Magnetic properties of self-assembled FeRh nanomagnets
Motyčková, Lucie ; Fruchart, Olivier (referee) ; Arregi Uribeetxebarria, Jon Ander (advisor)
Magnetické nanočástice a nanostrukturované materiály jsou velkým příslibem v mnoha oblastech, včetně biomedicíny, sanace životního prostředí nebo získávání energie. Proto neustále roste zájem o výzkum jejich jedinečných vlastností a vývoj uskutečnitelných výrobních postupů. Tato práce se zabývá metodou samouspořádávání, spočívající v povrchové precipitaci tenkých vrstev, za účelem výroby epitaxních polí nanoostrůvků ze slitiny FeRh na různých monokrystalických substrátech. Při tomto výrobním postupu zůstává zachována metamagnetická fázová přeměna nanoostrůvků. Morfologie a magnetické vlastnosti samouspořádaných nanomagnetů z FeRh jsou charakterizovány kombinací experimentálních technik a modelování, přičemž bylo zjištěno, že jejich rovnovážné tvary a magnetické uspořádání jsou navzájem propojeny. Kromě toho je navržena cesta pro získání volných nanočástic, která by mohla potenciálně umožnit využití metamagnetických nanostruktur v buněčných kulturách a biomedicíně obecně. Za tímto účelem jsou nanoostrůvky FeRh uvolňovány ze substrátu chemickým leptáním. Chování nanočástic a jejich reakce na teplotu a magnetické pole jsou studovány v kapalném prostředí. Metamagnetické vlastnosti separovaných nanočástic jsou charakterizovány pomocí vibrační magnetometrie.

Remote Control of the PC via GSM modem
Chroustovský, Petr ; Štohl, Radek (referee) ; Kučera, Pavel (advisor)
The aim of the paper is to describe a creation procedure of such a system of remote control of a PC that would employ GSM networks. It also provides an analy-sis of the topic and conveys how to produce an electronic module that would enable the user with the basic functions of PC control, i.e. switching on and off the PC, using the functions of reset, sleep and wake-up modes of the PC employing a GSM network terminal. The paper also deals with the problem of comparing the possibili-ties of producing such a proposed system with commercially accessible hardware or software solutions available.
