Control and signalling unit for sport match
Bohutínský, Jaroslav ; Chmelař, Milan (referee) ; Kolouch, Jaromír (advisor)
The aim of this study is a design of a control and signalling unit for sport meetings controlled by a microcontroller. The unit should display the time, the state of the match, eventually another data important for a course of the match. It should be fitted by an audible alarm of the end of the match. A touch control panel with a liquid crystal display serves as input of control data. The unit operates in a countdown mode, it is possible anytime to start or to stop the time by pressing the button. The equipment is mains-operated and backed up by an external battery. In the case of a power failure, it is switched over to the battery. A representation of the time, the state of the match and other data is done by LED displays. The unit allows a connection to PC.

Backup power supply with solar cell
Hrubý, Michal ; Brančík, Lubomír (referee) ; Kubíček, Michal (advisor)
Due to the modern trends of energy production from renewable sources, this thesis deals with backup power powered solar cell. Analyzes the principle of operation of the solar cell, describes its technological development. Describes types of commercially available accumulators and their specific properties and the recommended charging. It then focuses on the description of the activities used DC-DC converters and their specifics. The aim of this work is to construct a backup power device that uses USB, independent of the electric distribution network.

Control of water supply for a house
Chvátal, Michal ; Richter, Miloslav (referee) ; Macho, Tomáš (advisor)
The diploma thesis deals with the design and implementation of the system that will control the water supply for the family house and its garden. The system aslo allows you to store a history that can be viewed via the web interface. The web interface also allows you to set system parameters and monitor the current status.
