Analysis and evaluation of technical systems of motor operators of circuit breakers
Hurbanič, Jakub ; Valenta, Jiří (referee) ; Dostál, Lukáš (advisor)
This bachelor thesis was created as a overview and analysis of drive systems for moulded case power circuit breakers. There si an introduction to motor operators and their possible use with remote control and use in future in name of digitalization and elektrification. Also there is listed an analysis of opertors depending on the method of installation, switching power and the operator itself i.e. electric motor or electromagnet. There is mentioned the possibilities of controll and power supply of these operators and the positions of circuit breaker. In the end a small market analysis is executed and a short chapter dealing with measurment of electric motor operator in OEZ s.r.o. company.

Wireless IP Camera With a Raspberry Pi
Sidor, Peter ; Botta, Miroslav (referee) ; Červenka, Vladimír (advisor)
This thesis deals with the developing of an additional module for Raspberry Pi and with optimization of the efficiency of powering the whole device. The thesis also deals with the acceleration of the Operating System which is used by the entire device. The first part of this work describes the principles of functioning of the sensors and DC/DC converters. The work focuses on the selection of proper components for this module. The Printed Circuit Boards of the selected DC/DC converters were created in the program Eagle for efficiency measuring. As for the next part, there was created a program for turning on and off the entire device. This part presents a description of the possibilities of accelerating the operating system for Raspberry Pi. The last part of the thesis focuses on design of the final operating system.

Thermoelectric cooler construction
Murgaš, Martin ; Šnajdárek, Ladislav (referee) ; Brázdil, Marian (advisor)
Bachelor thesis will concern description of Peltier modules and detailed description of thermoelectric phenomena’s on which is principle of these modules based on. Thermoelectric materials and their properties will be mentioned as well as different applications of Peltier modules. Heat losses of the cooler will be described. Onwards it describes mathematical model of Peltier modules and their coefficient of performance. Also mounting of modules, types of power supply and types of regulation are mentioned. Experimental part consists of calculation and designing of cooling assembly.
