A Touch Sensor on the Glass Plate with a Backlit Pictogram
Jánešová, Daniela ; Levek, Vladimír (referee) ; Šťáva, Martin (advisor)
This thesis describes the solution of controlling device by capacitive-touch sensor. The geometry of the sensor is solved on standard printed circuit board, which is placed on the glass-made panel. In general, the theme of touch sensors is solved in the world by several companies and it is based on capacitive principles. They are described at the beginning of the work. By far, the main part of the work is focused on specific solutions with chosen integrated circuit for evaluation of touch sensor.

Low-power Security System of the Electricity-free Cellars
Klimeš, Martin ; Levek, Vladimír (referee) ; Šťáva, Martin (advisor)
The work deals with the available options of security devices for basements, design and implementation of its own security equipment. An FPGA chip from Xilinx was used as a device control. The device also contains a GSM module for sending information via SMS about space violation. Intrusion signaling can also be signaled by a siren. Intrusion detection is performed using a door and motion sensor. The whole device is powered by a battery, but there is also the possibility of mains power.

A Test Interface for Integrated Circuits with the Small Number of Pins
Tománek, Jakub ; Dvořák, Vojtěch (referee) ; Šťáva, Martin (advisor)
This study explores the possibilities for reducing the number of pins needed for scan mode interface. In the first part of this paper the existing solutions and methods that are usable for this purpose are described. Specific four pin, three pin, two pin, one pin and zero pin interfaces are designed in second part. Advantages and disadvantages of existing solutions and methods as well as designed and proposed interface are summarized in the conclusion.

Alternative conceptions of combustion engines
Šťáva, Martin ; Fojtášek, Jan (referee) ; Zháňal, Lubor (advisor)
The subject of this bachelor´s thesis on the topic Alternative conception of combustion engines is description of chosen historical and present alternatives to conventional piston combustion engine with crankshaft. The aim of this thesis is to create thesis that relates description of historical evolution of alternative construction combustion engines. Alternatives are described in terms of construction, operating principle and properties. In past were developed plenty of different conceptions of combustion engines. However most of them have never been successful because of many technical problems, complicated construction or other shortages.

A Design and Development of a Power Supply for Laptops in Ordinary Motor Vehicles
Urban, Michal ; Levek, Vladimír (referee) ; Šťáva, Martin (advisor)
Cílem této práce je navrhnout a sestavit napájecí zdroj pro notebooky různých výrobců pro použití v osobních a nákladních automobilech a na motocyklech s výstupním výkonem až 120W. Výsledný zdroj obsahuje USB-C konektor pro podporu napájení notebooků a chytrých zařízení s podporou Power Delivery, dále USB-A konektor s podporou Quick Charge 3.0 a také 12V automobilovou zásuvku pro možnost připojení dalšího automobilového příslušenství. Napájecí zdroj dále disponuje ochranou proti přepětí a přepólování vstupního napětí a také ochranou proti přetížení jednotlivých výstupů. Součástí zařízení je také LED displej, který uživateli umožňuje pomocí vstupního rozhraní jednoduše nastavit výstupní napětí pro notebook a sledovat aktuální hodnoty všech výstupů. Pro nastavování výstupu, indikaci a ochrany je použit mikrokontroler Arduino Nano.

Semi-automated Design of High-performance Digital Circuits with Xilinx FPGAs
Houška, David ; Dvořák, Vojtěch (referee) ; Šťáva, Martin (advisor)
Tato diplomová práce se zabývá návrhem sekvenčních digitálních obvodů s ohledem na optimalizaci zpoždění. V práci je popsána problematika dvou technik, které jsou běžně používané při optimalizaci – stručně je popsána technika tzv. synchronizace registrů (angl. retiming), větší pozornost je však věnována technice tzv. zřetězení (angl. pipelining). V rámci praktické části byla vypracována forma abstrakce sekvenčních digitálních obvodů pomocí acyklických orientovaných grafů. Obvod je tak přenesen do roviny, ve které je jednodušší jej transformovat. Zároveň je představen nástroj pro polo-automatickou optimalizaci digitálních obvodů vyvíjených v prostředí Xilinx ISE Design Suite využitím techniky zřetězení.

A Design and Development of a Universal Power Supply for Laptops in Contemporary Motor Vehicles
Cagáň, Adam ; Levek, Vladimír (referee) ; Šťáva, Martin (advisor)
This thesis deals with design of DC power supply with adjustable output voltage in range of 15 to 30 V, working in buck-boost topology. Thesis explains selection of buck-boost controller integrated circuit and calculation of values of external components. Designed converter is supplied with overvoltage, overcurrent, and reverse voltage protection circuit. Final circuit is equipped with microcontroller, display, and rotary encoder, which make it easily operable. Further, there are compared parameters of the device achieved in simulation and in practice.

A Digital Network-on-chip Architecture Model for Diagnostics
Valachovič, Marek ; Bohrn, Marek (referee) ; Šťáva, Martin (advisor)
Due to increasing integration on the chip, bus structure for on-chip comunication is less and less advantageous. For this reason, Network on Chip (NoC) was created as a solution to this problém. In this work, the basic blocks of the NoC architecture are described. The model of this architecture called Nonfire is described in detail, both function blocks, from which the router is created, and the network Interface Connecting this router with the Processing Element.
