User Interface for RoboDelivery Unit
Vostřejž, Tomáš ; Zbořil, František (referee) ; Uhlíř, Václav (advisor)
The aim of this thesis is to design and implement user interface for RoboDelivery service. In addressing the problem, attention is drawn to the fact that interaction with the delivery unit must be intuitive and cover the widest possible range of users, including users with visual, auditory or tactile disabilities. Furthermore, the designed interface is tested with the help of users. The result is an ODROID application.

Design of mechanical subsystem of tester for touch screen devices
Kopčil, Tomáš ; Venglář, Vojtěch (referee) ; Krejsa, Jiří (advisor)
Cílem této práce je navrhnout a sestavit systém pro automatizované nepřetržité testování dotykových displejů. Práce je zaměřena na mechanickou část, koncový efektor a motorizaci. Navržený koncový efektor je funkční na kapacitních dotykových displejích, přičemž snímá přítlačnou sílu působící na displej. Pohyb zařízení je zajištěn lineárními pohony s ozubeným řemenem, které jsou polohovány krokovými motory. Pro komunikaci s budiči motorů přes SPI protokol a pro samotné řízení motorů byla vytvořena knihovna zajišťující jejich lichoběžníkový rychlostní profil při pohybu. Sestavený testovací systém byl podroben 24 hodinovému spolehlivostnímu testu, během kterého byla ověřena jeho funkčnost, přesnost a opakovatelnost. Bylo také potvrzeno, že splňuje veškeré požadavky.

Graphics Library for Touchscreen LCD
Klubal, Ondřej ; Šimek, Václav (referee) ; Bartoš, Pavel (advisor)
This work deals with description of graphic library for a touch screen educational kit with a microcontroller from Freescale. Part of this library is a driver that accelerates gradient rendering and supports reading from video RAM. The library allows inserting images with transparency and their upscaling. Multiple fonts are also supported. Fonts can be upscaled and their weight can be set.

Time-domain switching device with three power outputs
Pavlas, Lukáš ; Macháň, Ladislav (referee) ; Šteffan, Pavel (advisor)
This bachelor work deals with the engineering design of Time Controlled Switch with Three Independent Outlets. It includes description of function, analysis of problems and suggestion for possible materialization. First, problems of capacity loads switching, following extreme conditions on the capacity outlets which are represented by short circuit state and by void state are analyzed and described. Then the work deals with the choice of components, suggestions for connection, design od printed circuit card and construction solution of the device. Finally, the work offers possible improvement of the design which consists in adding a complementary function of monitoring capacity loads or in a possibility tu use other communication technologies for remote setting of the device.

Traffic monitoring using Raspberry PI
Zacpal, Michal ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
This thesis describes the design and subsequent implementation of a unit for traffic monitoring using Raspberry PI. First section provides a quick overview of assistance systems, which use a road lane detection techniques. Next there is a description of two diferent methods for road lane detection. Follow the description of monitoring scene. Then the work describe the practical part including the design and realization of supporting electronics, selecting of each components, including the modifying of cameras, mechanical design and creating of unit. Another section is about selection and installation of appropriate software components necessary for running of the unit and the selection of development tools for creating user application. After description of graphical user interafce, there is a description of road lanes detection algorithm. At the end of the thesis is summarized a reliability of unit in real traffic situation. At the appendix there are technical drawings, describing the unit.

HMI automatic tester
Lang, Stanislav ; Žalud, Luděk (referee) ; Macho, Tomáš (advisor)
This thesis is dedicated to the automation of tests of the thermostats developed by the company Honeywell. The first chapter presents a problem of self-testing of thermostats, followed by a discussion of possible approaches to solutions. Attention is paid to testing the functionality of the HMI of thermostats, especially to the part of the system, that deals with activation of touchscteen, but no other part of the problem are omitted in the text. Discussions of the problematic passes into the design and implementation of specific design solutions. The selected design of 3D-router, which moves in three orthogonal coordinates and resembles to a coordinate drill for example. First, it describes the basic concepts of mechanic and electronic part of equipment, and subsequently is designed and implemented control electronics for mechanical activator HMI. Each of the electronics components are described in detail and values of parts are based on the calculation with the exception of finished parts. The proposal of the electronics follows the possibility of maximization of universality module for applications in similar applications. The functionality of the electronics is controlled by a microprocessor with a custom program that is described in the work. Source code of some the programs is not available because it is know-how of the company. Next part of the thesis deals with optimization of the moving of axes, optimization is done empirically by measuring. An important issue is compliance with the accuracy required position, also part of the work is devoted to the issue of calibration position. Finally is solved the continuity on the superior system. It is designed and implemented the upper layer of the communication protocol used in the company. Work is the solution of specific corporate award thesis. Although it is a very specific role of the works are generally applicable for other applications. In particular, the proposed electronic represents relatively universal controller for stepper motor control.
