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.

Hodnocení vybraných vlastností elektroodpadu
Skrovná, Michaela
The diploma thesis focuses on Evaluation of selected properties kind of electronic waste, mobile phones with touch screens. The literary part deals with a general description of electronic waste, mobile phones including their components. The experimental part is concerned with discovering of material composition of the explored telephones including their average material composition. 15 mobile telephones of various brands have been manually dismantled for the experiment. Another part consists of analysis of metal content in touch screens of mobile phones by a process of x-ray fluorescent spectrometry. It has been found out from the results that the manufacturer and production technology of touch screen phones influence the presence of metals. All researched phones contain precious and heavy metals. The main reason of the discovery is the influence of metals on the environment and human health.

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.

Automated Control and Monitoring of Central Heating for Older Buildings
Mužila, Matej ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The purpose of this thesis is a design of an automated heating regulation system for an old building. The thesis consists of a system architecture design, an implementation of the system, including prototype manufacturing of the required devices, and testing of the whole system in practice, with focus on functionality and efficiency. Several hardware devices were designed and manufactured, for which appropriate controlling software was implemented. The implemented software architecture enables users to control the system using a graphical user interface, and allows for an easy extension of the system. The graphical user interface, which is accessible both locally through a touchscreen and remotely using a web application, enables users to easily configure connected devices and regulated zones, and to set temperature level in the defined zones variably depending on a week day and time. The user interface also provides statistics about the heating system. The implemented automated heating regulation system was successfully tested in real conditions of a flat in a historical building. The system can be extended both hardware-wise and software-wise.

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.

Design of miniature thermal chamber
Červínek, David ; Bastl, Michal (referee) ; Chalupa, Jan (advisor)
This thesis is about designing and bulding temperature chamber. Main use for this chamber is to test devices which are designed in Mechlab laboratory. While I was developing this chamber I used Simuling for simulation of thermodynamic events. For LC filter simulation I used LTspice IV. Peltiers device is used as cooling/heating element. For calculation and control is used 3.5“ touch screen programmed in 4D Workshop. Final device is capable to automatically maintain set temperature in range of -13°C to 80°C. Temperature can be set as stationary or cyclic between two predefined temperatures. User can also choose temperature that will be used by regulator.
