Intelligent BMS for lithium batteries
 Vašíček, Jakub ; Kazda, Tomáš (referee) ; Vyroubal, Petr (advisor)
This thesis is focused on design of electronic system called BMS, which is necessary for lithium batteries safety operation. The first part contains a brief description of lithium battery design. The following is an overview of the main parameters of this type of batteries. The next part describing various methods of state of charge (SoC) estimation and the ways to ensure uniform charge of each cell. Based on the theoretic analysis, the block diagrams for individual parts of BMS were designed. The following describing device assembly and design of control algorithm. The last part is devoted to measurement of achieved attributes. In conclusion, results of the work are discussed and possibilities of future improvements are suggested.

Design and implementation of revisions devices for the treatment of hyperhidrosis
 Vejnar, Pavel ; Bradáč, Zdeněk (referee) ; Šedivá, Soňa (advisor)
Thesis deals with the design and realization of revisions devices for the treatment of hyperhidrosis. One of the methods how to treat hyperhidrosis is iontophoresis. This prevents sweating using an electric current. The work is divided on the parts. First part is a theory, which deals with basic principles of treatment. Next part is the analysis of original solutions and hardware design of new solutions. In conclusion I revive device by microcontroller programming and checking its functionality. I was able to create a prototype board, programmable firmware and successfully tested a prototype.
