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.

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.

Touch Screen User Interface for Electric Car
Martinák, Ondřej ; Ráb, Jaroslav (referee) ; Kolář, Dušan (advisor)
Tato práce navrhuje dotykové uživatelské rozhraní pro elektromobily. Rozhraní bylo navrženo tak, aby bylo pohodlné na použití pro řidiče a aby bylo snadné z něj vyčíst potřebné informace. Aby bylo možné toto rozhraní integrovat do elektromobilu, tato práce také navrhuje potřebnou softwarovou a systémovou (hardwarovou) architekturu. Nakonec shrnuje co je ještě potřeba udělat, aby bylo možné celý systém integrovat.
