Design of programmable control system
Trpiš, Michal ; Říha, Kamil (referee) ; Koula, Ivan (advisor)
The goal of diploma thesis is design of programmable control system. This system can be used for regulation of basic parameters in an aquarium. Primary parameters for selection of this device are the price and the easy realization of final device. In first step there are selected parameters, which are needed to control. In second step there is described which kind of sensors can be used for measuring of selected parameters and suitable regulation of necessary parameters. The device is supposed to communicate with PC by USB and this communication is going to be compatible with an old RS-232. Device must be completed with hardware design. Device will be in principle system with real time, that is the reason why device will contain microcomputer. A microcomputer must communicate with other integrated circuit in the device and it supposes to communicate with PC. In specific chapter it will be described, how many different kinds of communication it is possible. For microcontroller it is necessary to create a program, which can figure the measured parameters and it also allows setting up the way how parameters can be regulated. Measured parameters are supposed to storage in the specific memory for the later interpretation. The completely device must be put into a case, which is calculating with a damp place. There must be created a host application for PC. This application suppose to detect if device is connected, figure measured parameters and also allows to set up the way, how to regulate the parameters and display the storages parameters. The application is suppose to run on the operation system created by Microsoft (Windows XP and Windows Vista or later). Diploma thesis contains a problem of the analysis which parameters may be controlled and the way how it can be controlled. There will be selected the sensors, which are suppose to measure and there will be described the basic data transfer and the specifications. It will also contain description of the hardware and software implementation of the device and possibilities of the user’s settings. There will be described the host application and its possibilities. Finally there will be described a functionality of the device and the host application. It will be also imagined some system upgrades for future.

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.
