Digitally controlled power supply
Madron, Martin ; Šotner, Roman (referee) ; Kubíček, Michal (advisor)
This bachelor´s thesis is about design of digitally controlled power supply. The introduction describes the basic principle of power supplies and their division. The thesis deals with solving the adjustable current source with adjustable current cutout. The solution of supply was made using linear stabilizers L200 controlled by digital potentiometers. Control handles microcontroller ATmega16 from Atmel. The user interface is realized by the matrix keyboard and LCD display. At the conclusion of the work there is a selection of the structural components.

Advanced waterproof flashlight for extreme condition
Šerík, Martin ; Kubíček, Michal (referee) ; Kincl, Zdeněk (advisor)
The work is focusing on the search for available solutions concerning the choice of components for advanced waterproof flashlight for extreme conditions and on building this device. After comparing the individual parameters the following components were selected: as a source of energy - four AAA batteries eneloop distributed by Sanyo, high-brightness LED CREE XP-G and microcontroller ATtiny24 distributed by Atmel. The user interaction is realized by support of capacitive touch buttons and the charging of the lighting device is wireless. The light is placed on the handlebar using a specialized holder.

FPGA-based pulse classification
Ihnát, Kryštof ; Matěj, Zdeněk (referee) ; Kubíček, Michal (advisor)
Cílem této práce je seznámení se s problematikou detekce ionizujícího záření a jeho detekcí zejména pomocí proporcionálních detektorů a navrhnutí algoritmu pro jejich klasifikaci a jeho následná implementace do FPGA. V první části práce je obecně popsáno, jak jednotlivé typy plynem plněných detektorů fungují. V druhé části je věnován prostor algoritmům pro klasifikaci pulzů, které se objevují v literatuře. Následuje návrh vlastního algoritmu, jeho rozbor a rozebrání výsledků. Ve třetí části následuje popis samotné realizace navrhnutého řešení na platformě RedPitaya. Je zde rozebrána celková architektura navrhnutého systému, detailně popsány jak jednotlivé bloky v logice FPGA, tak i ostatní skripty zajišťující zpracování naměřených výsledků a jejich vizualizaci.

Vehicle Safety Systems
Langr, František ; Kubíček, Michal (referee) ; Povalač, Aleš (advisor)
This thesis looks into car industry safety systems research and an appropriate implementation into a scale model (demonstrator). For the model there are selected active safety systems based on distance sensors of various principles. The thesis contains a detailed description of the selected sensors together with the selection of a suitable demonstrator control device. There are active and passive safety and vehicle assistance systems explained. The thesis further discusses the design of individual 3D printed parts of the demonstrator chassis and their development. The components and circuitry of the PCB are also described, along with the safety algorithm used and the operating firmware.

Remote control of FPGA-based embedded system
Král, Jan ; Stejskal, Vojtěch (referee) ; Kubíček, Michal (advisor)
The bachelor’s project looks into the development of a part of Digitizer embedded system. The design is focused on the usage of FPGA-based processor managing the remote control operations and on the achievement of the sufficient bitrate for transmitting data to the ethernet network. The project summarizes used solutions and evaluates their applicability in the developed system. Matching concepts of solved problems are designed properly; in most cases they associate positive properties of used solutions. The implementations of MicroBlaze processor system and chosen modules were performed into the target device and the desired characteristics were measured with successful outcome.

FPGA IP core for Sony IMX sensor interface
Musil, Milan ; Kováč, Michal (referee) ; Kubíček, Michal (advisor)
The diploma thesis deals with the implementation of the SLVS-EC interface into the FPGA. This interface is used in new SONY’s image sensors for high-speed data transmission. The introduction contains a description of the interface, its possible configurations and comparison with the sub LVDS interface used so far. This is followed by the selection of a suitable MPSoC with the Zynq Ultrascale+ architecture with focus to its hardware resources for receiving a high/speed signal. The main part of this thesis deals with the design of receiver for the SLVS-EC interface and decoding of the data. The raw image data is then stored in external RAM. At the end of this thesis is described the chosen methods of testing partial parts and overall design.

Design of double stabilized power supply
Vlček, Pavel ; Kubíček, Michal (referee) ; Brančík, Lubomír (advisor)
This work deals with a design scheme of a laboratory power supply with high stability of output voltage and additional protections for safer operation of both powered device and the power supply itself. The work describes complex construction of power supply from the design of scheme in the simulator, through its tuning to the required parameters and the design of mains transformer to the construction and building of resulting device applicable in a laboratory. In addition, measuring and evaluation of achieved parameters, such as the ripple of the output voltage, the velocity of reaction current limitation, velocity of reaction the thermal electronic fuse are given.
