Electronic load
Škotnár, Martin ; Pavlík, Michal (referee) ; Boušek, Jaroslav (advisor)
This thesis deals with electronic load design. In the beginning of the thesis, the necessary theory for understanding the basic properties and principles of electronic loads is described. Current control is provided by a touch screen and a microprocessor. The work presents a detailed design procedure in terms of hardware and testing, as well as a printed circuit board design procedure. The result of the work is a fully functional electronic load. The main use consists in testing equipment such as power supplies and accumulators.

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.

Utilization of TV Touch Screen (plasma) in CT24 News
Prokeš, Martin ; Lokšík, Martin (advisor) ; Géla, František (referee)
In this thesis, the author deals with a topic focusing on use of plasma screens and plasma technologies in contemporary news channel CT24 broadcasting. The thesis is contained of theoretical and practical part. In the theoretical part, the author summarizes existing findings of the television news field. The theoretical part includes a basic definition of television news and its subsequent changes, primarily because of digitalization process. In the connection with digitalization, the author also deals with new formats of television news, such as TV graphics. In the second half of theoretical part, the author focuses on characteristics of Czech Television and CT24 news channel. It contains of brief description of programs and studies, from which CT24 broadcasts, and which are closely related to use of plasma technologies. In the practical part, the author then focuses on the specific use of plasma technologies in the broadcast of CT24 channel. First, the author offers a basic division of what these elements are used for in broadcasting. Based on his own experience and interviews with Czech Television staff, he then describes the use of plasma technologies in individual programs and studios and offers their comparison.

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.

Infotainment unit for car
Musil, Roman ; Burian, František (referee) ; Ligocki, Adam (advisor)
The aim of this thesis is to design device which extended functionalities of on-board computer. The thesis first deals research of available single board computers and then selecting the appropriate touch screen, then analyzing the communication protocol which is used to communication between devices. Further, the thesis deals design architecture of system, creating a graphic interface and archiving telemetry data. Subsequently, deals creation of an interface that allows the visualization of archived data on a desktop computer. And finally, the implementation of online vehicle monitoring through the GSM module. The conclusion summarizes obtained information and the results achieved.

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.
