RFID bus-stop identifacation for sightless people
Straka, Radomír ; Zamazal,, Michal (referee) ; Dušek, Martin (advisor)
The aim of this master’s thesis is to design a device for identification of bus stops for blind people. In the beginning the work describes information about the RFID system, characterizes each part of this system, mutual communication of its components and evaluates possibilities of RFID communication frequency bands. Subsequently the work describes the block diagram of the device and the circuit scheme of each block. Work concentrates on a selection of circuit components for the RFID transceiver, the voice module, the control module and choose a suitable transponder to place it on metal constructions. Control programs are also described. PCB design of each board, partlists and source codes are in the appendices of this master’s thesis.

Forming Machine Control System
Vaško, Jiří ; Fojtík, Pavel (referee) ; Kučera, Pavel (advisor)
This master thesis deals with the implementation of the control system for the forming machine used in producing of confectionery forms. The introductory part describes the forming machine from the point of important control elements. The second part is associated with the hardware design of the control automat and description of main functional units on the control PCB, as well as on other PCBs. The following text presents the communication protocol between the control automat and PC and after that there is a description of the CPU firmware. The final section brings the characteristics of the PC application for a connection with the automat.

Board computer for car
Lutera, Ondřej ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
This thesis deals with the design and implementation of car computer with multi-user mode and data recording. The measurement is performed by using a direct connection to the sensors and fuel injector of engine. The measured signals are processed and evaluated by Atmel Atmega128A microcontroller. Measured and recorded data are displayed on the graphical LCD.

Auxiliary sensorics for unstable balancing vehicle
Solnický, Vojtěch ; Krejčí, Petr (referee) ; Grepl, Robert (advisor)
This thesis continues on successful project of unstable balancing vehicle, which was completed in mechatronics laboratory in last year. The main goal is to supplement vehicle with display device displaying driving conditions. These conditions have to be acquired first from several sensors. Other issues, which are dealt in this thesis, is problem with damage of electronics due to induced voltage in DC motors with permanent magnets, built-in sensor for obtaining information about driver’s presence and logging driving conditions on SD card. In the end there is described implementation of sensors’ output signals verification.

Datalogger with parallel data logging
Havlena, Marek ; Minář, Petr (referee) ; Zuth, Daniel (advisor)
This Bachelor's thesis is dedicated to the design and implementation of the Datalogger module, which stores data in two different memory storages. First memory storage is solved by using an SD card and the second is the internal EEPROM memory of the microcontroller. It also deals with data synchronization between these memory storages. Communication between the cards is through the SPI bus and communication with the module is provided by a serial interface designed by USB transmitter (UART).

Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.
