Power source for pulse magnetron sputtering
Schulz, Jakub ; Magát, Martin (referee) ; Šteffan, Pavel (advisor)
The presented thesis deals with the design and assembly of the generator for pulse magnetron sputtering. The designed device is capable of generating two square wave signals via its counter-working outputs. Both signals have independently adjustable frequency, pulse count and duty ratio. Both signals originate from two frequency syntheses controlled by microcontroller PIC16F877A. All the settings are entered by four buttons and are shown on an alphanumeric display with 16x4 characters. The duty ratio is adjusted using a special module.

Internet Interface for Teaching and Learning
Belko, Jakub ; Magát, Martin (referee) ; Šandera, Josef (advisor)
Bachelor thesis Web interface for presentation and training applications is capable of presenting learning texts made in PowerPoint. The application allows queries over viewing the presentation and provides communication between teacher and student. The application was created so that it could not control user-consuming. In implementation used only freely available JavaScript libraries. Bachelor's thesis is largely implemented the instructions for use applications.

Inteligent battery charger controled by microcontroler
Burda, Petr ; Magát, Martin (referee) ; Pavlík, Michal (advisor)
Universal, smart battery charger NI-Cd, NI-MH, Li-Ion a Li-Pol batteries with adjustable voltage incremental rotary position sensor in the range of 0 -25 V and currnet up to 1 A load.The charger is controlled by microcontroller ATMEGA32 – 16PU Atmel and provides thermal protection and management of the chrging voltage depending on the temperature inside the battery pack or battery cells. Setting is made througth LCD screen to be displayed in addition to the set temperature, charging voltage and battery current. To save the profile is used EEPROM memory, which is contained in the microcontroller.

Digital controlled analog guitar efects
Novotný, Jan ; Magát, Martin (referee) ; Pavlík, Michal (advisor)
This project contains theoretical part guitar effects and their setting about. Theoretical part continues in selection of parts for ddriving of effects and parts for the driver. Another parts are: get data from peripherys (switches, ratate encoders), using data, comunication between microcontrolers, setting effects and printing effects setting on graphical LCD. Practical part of this project is basic communication with graphical LCD, design and development of driver about.

Pressure Sensors Based on Modern Nanotechnologies
Magát, Martin ; Hudec, Lubomír (referee) ; Vlach, Radek (referee) ; Vrba, Radimír (advisor)
This thesis describes utilization of a nanotechnology in new pressure sensors. Detailed analysis of individual principles are carrying on. And simulations and experimental models of sensors are developed. More detailed description is provided for new capacitive pressure sensor, which is manufactured using nanotechnology, including its model and analysis in order to improve its properties. The work deals with the emission pressure sensor which uses the principle of cold emissions, including analysis comparison of the measured values of the emission current from the applied nanotubes field and analysis to improve emissions performance.

Precise adjustable power suplly
Pawlas, Andrzej ; Magát, Martin (referee) ; Kadlec, Jaroslav (advisor)
This bachelor´s thesis deals with the proposing precise switching power supply. This switching power supply works with a maximum of 99 % duty cycle. Input voltage is 12 V and output can be set in the range of 1.2 V - 11.9 V. Current can be a source of burden 0 A - 20 A. The entire power supply is controlled by microcontroller. While addressing the proposal switching power supply have been developed five prototypes. Last prototype works well, but the output appeared significant interference.

GPS position recording system
Kokeš, Ondřej ; Magát, Martin (referee) ; Kadlec, Jaroslav (advisor)
The system conducting an electronic record of drives employing GPS enables simply track the vehicle running and traffic. As vehicle is running, information is gathered and saved into the memory module, out of which the driver's report book is generated afterwards. The submitted work is involved in brief summary of possibilities that might be used during implementation of the project and furthermore during complete solution of such a system, hardware and software parts included.
