DC motor controler with feedback
Dundáček, Martin ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with DC motor control. Main goal was design and realization of DC motor controler module with feedback. The first part dwells on methods for DC motor control and HW design of control module. The second part describes development of software for the module, testing and sums up results.

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.

Design of Home Theater
Knápek, Michal ; Buganská, Tamara (referee) ; Křenek, Ladislav (advisor)
The main aim of my bachelor´s thesis is to find new approaches and new ergonomic, technical and esthetic solutions which satisfy the latest requirements for domestic devices of today. The result should be a design that is modern in appearance and technology should also show a new direction for the design of home theater could take. Another aim is also to fulfill psychological and social function and in order to appeal more to the public and suspended to its beauty.

Unit for communication in scientific instruments
Hucl, Václav
We made device for communication between the computer and devices connected to the communication CAN (Controller Area Network) bus in the laboratory. This equipment generates four independent branches of the bus, which can communicate with each other, but short circuit, disconnection or other disorder in one of the branches does not affect the other three branches. Using the CANHUB card we can also interface devices connected CAN bus to a computer via USB or Ethernet. The hub consists of two AMIS-42770 integrated circuits. CAN/USB and CAN/Ethernet interface functionality is provided by a pair of Freescale 56F805 microcontrollers. The maximum communicating speed is 800 kbps while the devices in all braches of the bus must be set up to the same communication speed.

Design and implementation of modules for teaching and developing applications with microcontroller Atmel AVR
LANGMAJER, Miroslav
This thesis is based on the design and production of teaching kits with expansion modules which are based on the Atmel AVR microcontroller. Kit consists of a plate containing processes and basic power modules directly on the board and expansion modules "SIMAČ". "SIMAČ" modules are virtual elements that simulate the real elements and they are commonly used in industrial automation. Because of their cost they are integrated in extension kit as programmable modules. It also contains basic theoretical information about working with ATMEL AVR microcontrollers. Expansion modules with module development board and disc which will be loaded all the schemes, programs and technical documentation for individual districts will be attached to the thesis.

The air track
KAKAŠ, Štefan
This thesis concern deal with many problems: using computers at school education, mechanical construction and development hardware and software of the school didactic utility with the name air track whose financial costs for fabrication I tried to minimize for aim repeated using in the school arrangement where it should service as utility education kinematics and dynamics.
