Measurement of the vibrations
Diblík, Jan ; Kolouch, Jaromír (referee) ; Biolková, Viera (advisor)
Diploma thesis is focused on principles of measuring the vibrations using accelerometers and using them for making vibration measuring instrument with focus on modern integrated digital accelerometers. In the first part are described ways to measure acceleration and vibrations with available technical supplies with respecting place and purpose of measuring. In practical part are measured characteristics of used sensor, instrument for measuring vibrations is designed and built and for few experimental object vibrations or acceleration are measured and graphical interpreted.

Wireless safety appliance
Čapek, Lukáš ; Kováč, Michal (referee) ; Kolouch, Jaromír (advisor)
The purpose of this project is to secure an object, for example bicycle, buggy,merchandise. Protecting device consists of a sensor unit and a pager unit. Both of these units contain a transceiver which works in ISM band. Operation circuits drive microprocessor AVR with low power technology because of possible battery supply. Sensor unit is monitoring the state of sensors and battery discharging. This unit can use accelerometer sensor and two contact sensors. The pager unit indicates alarm, the state of battery in both units and signalizes loss of connection.

Control and signalling unit for sport match
Bohutínský, Jaroslav ; Chmelař, Milan (referee) ; Kolouch, Jaromír (advisor)
The aim of this study is a design of a control and signalling unit for sport meetings controlled by a microcontroller. The unit should display the time, the state of the match, eventually another data important for a course of the match. It should be fitted by an audible alarm of the end of the match. A touch control panel with a liquid crystal display serves as input of control data. The unit operates in a countdown mode, it is possible anytime to start or to stop the time by pressing the button. The equipment is mains-operated and backed up by an external battery. In the case of a power failure, it is switched over to the battery. A representation of the time, the state of the match and other data is done by LED displays. The unit allows a connection to PC.

Laboratory kit for design work with Altera CPLD devices
Gajdošík, Petr ; obrany, Petr Bojda, Univerzita (referee) ; Kolouch, Jaromír (advisor)
In this thesis I aim at a design of the laboratory kit and study ways how to programme CPLD devices made by Altera company. The product is used for development and demonstration of applications in CPLD devices made by Altera company. The kit is designed for Altera programming cables and Presto (made by ASIX). Input signals are implemented by a set of switches and buttons on the board. Output states are displayed by LED diods, possibly connected to multiplex the display. The user can connect to external devices via external inputs. Thesis is also aimed at the design PCB of the laboratory kit, subsequent production, recovery and verification of compatibility ALTERA and PRESTO programmers. End of the thesis aims on working with the Quartus II design environment. In particular, it is a guide to working with templates and simulation of VHDL designs.

Communication between FPGA and computer - USB high speed
Kollár, Tomáš ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
This bachelors thesis is about a possible interconnection method of FPGA (Field-Programmable Gate Array) chips with the PC through the USB 2.0 bus. These programmable arrays are very important nowadays mainly because of their high speed and high flexibility. Such properties make possible to use FPGAs in applications that require small data bandwidth and also which can utilize the whole bandwidth offered by the USB 2.0 bus. This thesis deals with possibility to use such transfer rate and its short description followed by the design of PCB layout. As the communication between the FPGA and the PC is made possible with the help of a microcontroller capable of handling such requests, I decided to include a short description of its functionality and working principle description in the thesis. The last part describes the communication through the GPIF interface for high-speed transfers.

DC/DC converter 12 V to 300 V
Buba, Ondřej ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The thesis deals with design of switching power supply to power the oscilloscope. In this project the topology of the DC-DC converter is chosen, the pulse transformer and the output coil is designed. The control circuit is also choosen a suggested. This circuit will be replaced with microcontroler ATMEL in the second part of this thesis. The microcontroler will be programmed to replace the control circuit.
