TV Distribution Network Signal Analyzer
Matyáš, Pavel ; Šebesta, Jan (referee) ; Povalač, Aleš (advisor)
Aim of this project is development of the analyser for cable distributed television signals. At the beginning is a block diagram of the suggested analyser with digitally controled wideband tuner, logarithmic detector, microcontroller and a graphical display module. For each block there is a theoretical analysis, features description and description of the electronic components that were used. In the next part of this project is introduced the design of circuit schematic and printed circuit board of prototyping kit, that was used for experiments and testing of its features and parametres. Last part of this thesis focuses on finishing of a prototyping kit, development of firmware and experimental verification of the prototype's parameters.

Communication and control card for electron microscope
Robotka, Jan ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
The main aim of this thesis is to design a communication and control card for an electron microscope, eventually for other equipments of the company Delong Instruments a.s., which is dealing with its development and production. This card should replace existing communication card because of its low computational performance. Also, it should replace control and measure card manned with A/D and D/A converters. Thus, the new card will be providing not only the communication with a superior PC and other electronic systems, but also the control of other subsystems of the electron microscope, the determining of processional states and the measuring of internal physical quantities. At the beginning the requirements were determined and the main concept was made with the inclusion of the simple block diagram. It was very important to choose a suitable microcontroller, which will be an intelligence of the whole card and so it will be the most important component. The accent was set mainly on the sufficient computational performance, high modularity of its periphery, good vision of the future innovation and support and, of course, the price. The next requirement was the implementation of the Ethernet, which will be used for the communication between the card and the superior PC. The microcontroller which was chosen have the core architecture ARM Cortex-M3 and it is described in separate chapter. The next part of this thesis is dealing with the main communication standard of the card, which is the Ethernet. After the general description, the Ethernet was mainly discussed in context of the chosen microcontroller. The possibilities of the application of higher layer TCP/IP protocols were also discussed. Implied part of the thesis was the selection of other important components, especially A/D and D/A converters. Its characteristics will have a big effect on the characteristics of the card. In the last and the most important phase the electrical scheme was designed and it was described in detail. This scheme is the main result of this thesis and it is the main document for the future realization. Designed card will be able to process and control 16 differential analogue input signals, 16 differential analogue output signals, 8 digital inputs, 8 simple digital outputs and 4 digital outputs triggered by optocouplers. It will be able to communicate with the superior PC over the Ethernet with the maximum bit rate of 100 Mbit/s, with other electronic cards over the serial line UART through the optical fibers and with other internal and external equipments over the RS-485 and RS-232.

CNC - design and contrlol
Matoušek, Vojtěch ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
My task was to build a smaller structure triaxial CNC milling. I designed electronics for motion control. The main part is the implementation of the control unit, which will provide control of the machine. The work includes the complete design, PCB design and program description for the uP ARM. The unit can work independently as well as hardware interpolator connected to the PC.

Internet based control of laboratory models
Dobrovolný, Petr ; Smrčka, František (referee) ; Zezulka, František (advisor)
This award solves design of two models that are designed to teach on PLC and in the future on the Control Web. Both models should be used in LabLink system, which allows you to remotely working on laboratory tasks. The first software model simulates the movement of trains on rail in relation on control from the PLC. The second model is a physical model of drill. In both models are solid managing and type of construction, which allows operation without physical intervention.

The Upper Limb Prosthesis And Its Impact On A Patient's Mental State
Štechová, Eva ; Bachura,, Marek (referee) ; Zdařil, Zdeněk (advisor)
Bachelor's thesis deals with myoelectric upper limb prosthesis and it's effect on mental state of the patient. It was created as a collaboration with company OTTOBOCK SLOVAKIA s.r.o, company that distributes prostheses and other devices to help improve or preserve mobility for disabled patients. I chose one of their products, Greifer, and decided to do a redesign. Greifer is a prosthesis made for delicate work with small objects on one hand, on the other for harder work that requires a firm grip. I created the design with regards to ergonomics, functionality and aesthetic quality. My aim was to create a product that a patient would easily get used to, and it would not draw negative attention of other people, which would have negative effect on a mental health of the patient. Functionally I followed the today's Greifer system provided by Ottobock at first, but then I added the function of rotation around spherical joint, inspired by an actual human wrist joint.

Hydraulically driven screens
Forman, Ladislav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main objective of this work is the calculation of selected parts of hydraulically driven screens such as cleaning equipment before entering the small hydro power plants. The thesis is divided into two parts. The first part focuses mainly on the calculation of hydraulic mechanism for cleaning screens. The second part contains a drawing of the general assembly hydraulically driven screens and sub-assemblies.

Mechanical construction of hydraulics arm
Vodrážka, Jakub ; Březina, Lukáš (referee) ; Věchet, Stanislav (advisor)
This bachelor’s thesis deals with design of a hydraulics arm. The main purpose of this hydraulics arm is the possibility to use it in education project which is a part of hydraulics systems lessons. This arm consists from few parts which are connected together by rotary joints. This arm is actuated by linear hydromotors, furthermore there is a magnetic position sensor. Autodesk Inventor 2008 was used during the arm design process. There are three main parts in this work. First part deals with fluids systems, the second part shows the position sensor properties and the last part presents some cases of arm design with deformation verify. A lot of supplement is presented at the end of this work as pictures of the model of the arm or pictures of some parts of the model.
