Control of house heating
Hnyk, Marek ; Šandera, Josef (referee) ; Šteffan, Pavel (advisor)
The aim of the final thesis is a proposal and implementation of a system which would enable a heating control on the basis of data gathered by monitoring of particular rooms inside a building. In particular, it is focused on water measurement within the heating system, TUV (non-potable hot water) and the temperature within the space of residential rooms. The system headquarters must enable an automated saving of the measured data. Selected temperature figures will be made accessible by a web interface and continuously saved on the web server.

Service device for automatic sanitary equipment
Kudláček, Martin ; Levek, Vladimír (referee) ; Šteffan, Pavel (advisor)
The aim of this thesis is to inform readers about the basic principle of electronics for which the service module for the automatic sanitary technique will be designed, as well as design and describe the most important parts of the module theoretically. Likewise, the thesis deals with the most common mistakes in the design of printed circuits boards with respect to the resistance of the resulting device against interference. The implementation itself includes both module design and a communication algorithm for connecting multiple service modules and their remote control using the Raspberry Pi minicomputer. The thesis also contains a design of algorithm for verification of data transmission by the transmission system.

Precise LED lamps dimming for stage technology
Šojdr, Marek ; Šteffan, Pavel (referee) ; Levek, Vladimír (advisor)
This bachelor´s thesis discusses the problems of dimming of LED bulbs using DC voltage. It explains basic converters topologies and power factor correction options. Part of the thesis deals with the subharmonic oscillation and possibilities of its elimination. Describes the design of the circuitry of dimmer module for precise dimming of selected types of LED bulbs, revival and testing of the dimmer module. Part of the work is basic for realization of the dimmer (printed circuit board, list of components).

Electronic game Logic
Zemanová, Renata ; Šteffan, Pavel (referee) ; Háze, Jiří (advisor)
The goal of this bachelor thesis is to design and manufacture an Electronic game Logic. This electronic game should look like the board game and also respect the game’s rules. The electronic game is designed as one PCB that contains control electronics and play units. The functional PCB containing all electronics was manufactured. The game was programmed, and the final version was placed in a designed case. The Electronic game Logic also allows the player to set game mode options.

Distance and position determination using ultrasound
Bartoš, Dalibor ; Šteffan, Pavel (referee) ; Hejátková, Edita (advisor)
This thesis describes distance measurement using ultrasound and its application in determining position of an object. First part of this thesis describes principles of ultrasound wave propagation, piezoelectric transducers, basics of both triangulation and trilateration and different kinds of park assist systems. The second part contains description of algorithms designed to determine position of two objects at the same time. Last part of the thesis describes implementation of created algorithms into software and also modules used in the test measurement.
