System for position monitoring
Brouček, Jan ; Younes, Dina (referee) ; Šteffan, Pavel (advisor)
Bachelor's thesis contains design of device that is able to determine its own location by the GPS. Detected location data are stored on the memory card microSD and they are optionally posted on the web server via the GSM network. Data are stored in GPX format, ensuring the compatibility with commercially available programs and devices. Planed usage of device is for informational tracking of moving objects, or as a car security feature, which can inform user about car position.

Inertial Navigation Unit
Dvořák, Jan ; Hubík,, Vladimír (referee) ; Šebesta, Jiří (advisor)
This thesis is focused on the design and realisation of inertial navigation unit INS. The unit is capable to measure, store and send data to a PC in real-time for a later offline processing. The first part of the thesis introduces the reader with the basic principles of accelerometers, gyroscopes and MEMS sensors. An introduction to coordinate systems and measuring errors is also included. The second and third part of the thesis deals with the analysis of the solution and the implementation of the INS unit. The fourth part of the document is dedicated to the software for the INS unit. This thesis concludes with explanation how the gathered data are processed.

SD Card Reader Based on HC(S)08
Hřib, Dalibor ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The aim of my bachelor's thesis is to design and programme the SD card reader using the Freescale HCS08 microcontroler, namely MC9S08SH32. A part of this thesis is a design and making of a printed circuit board for the card reader and an operating software written in the C language. The software is able to use the FAT16 and FAT32 file systems for reading the directories and for reading and writing files of unlimited length. The card reader has RS232 and IIC interfaces and one free port for connecting to the card reader and other device, for example personal computer.

Ventilation Control Unit with Radio Time Synchronization
Barták, Jiří ; Šimek, Václav (referee) ; Tříska, Vít (advisor)
Project's primary objective was to create ventialtion control unit, which synchronizes its time through radio signal. Delivering power into fans is based on dew points calculated from data obtained on both sides of circumferential wall. The most important parts of this unit are microcontroller MC9S08DZ60, sensor SHT11 and DCF77 receiver. There is SD card socket on the inner printed circuit board for data recording purposes. I am working with the card on file system layer. The control unit uses USB socked as well to be able to communicate with PC. I have decomposed firmware of control unit into small modules at the start of development. Those modules are: MCU to MCU communication, USB communication, measuring temperature and relative humidity using SHT11 and extracting time information from DCF77 signal, all written in C. After these modules were tested, i have put them together. I have also written a PC application in Java. It is used to communicate with control unit and to process recorded data. Benefits of the control unit cannot be evaluated without long-term observation.
