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.

Small programmable bench power supply
Čech, Jonáš ; Vochyán, Josef (referee) ; Kubíček, Michal (advisor)
This bachelor‘s thesis deals with design and construction of compact low power switching power supply, which is powered from USB. It provides adjustable output voltage in range from 0 V to 16 V and adjustable current limit. The design is made with respect to galvanic insulation between device and PC. The control of device is done by basic user interface and software, which provide monitoring of output voltage, current and output power. The simulation and measurement results are included.

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.

Simulator for Passive Multi-Static Radar using WiFi/WiMAX
Sládek, Ondřej ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
This master’s thesis deals with the concept of passive multistatic radar. The radar system exploits WiFi or WiMAX transmitters as the source of radiolocation signal. The transmitters are considered non-cooperative. The master’s thesis evaluates limitations arising from utilization of WiFi or WiMAX signals. A Matlab simulator was created as a part of the thesis, which was used to verify the basic idea behind this concept. Based on the results of real-life simulations, conclusions are suggested towards a possible application of WiFi/WiMAX radar.

Design of synchronous switched-mode power supply for automotive
Sedlák, Jakub ; Šebesta, Jiří (referee) ; Kubíček, Michal (advisor)
This bachelor´s thesis deals with the DC/DC convertors and their application in automotive lighting. In first part of thesis, there are mentioned DC/DC convertors, their basic topologies and synchronous rectification. In next part of thesis, there are compared selected integrated circuits, which are suitable for this application. For one of these circuits is created a design. For this design was created a simulation to find out, that design is working. This design was realized and was tested according to automotive standards. In the end, there is a working DC/DC convertor, which meets requirements and basic limits from automotive standarts.
