Children and their safety
Bednařík, Josef ; Jiroušková, Ivana (advisor) ; Lustig, Stanislav (referee)
My Bachelor thesis was filmed for precautionary measures information sketches. These short movies named " children and their safety" . That contains playing scene with various situation from their child hood . The sketch was filmed by theme and technically skript. I used edition program named Pinacle Studio. Theoretic part Bachelor work set the target tuitionary scatches which is focused children and thein interactive education. Next part is about preparation and work with camcorder as well as accessories for filming. I focused in the end to apply scatches in prectice, piece of knoledge and gain experience process of filming.

Design and implementation of wireless charging for embedded systems
Bednařík, Josef ; Bastl, Michal (referee) ; Krejsa, Jiří (advisor)
This thesis deals with the design and realization of wireless power charging circuit for embedded systems. The research section focuses on the various ways and technologies used in applications of wireless power transfer. The theoretical part also briefly characterizes resonant inductive coupling and critical parameters of the transfer. This is followed by realization of various variants of transfer coils and electromagnetic oscillators. Wireless power charging prototype system is created and used for testing purposes to find optimal configuration of resonator. The hardware unit presented in the final part of the thesis exploits microcontroller and implemented software is extended by foreign object detection algorithm along with method to monitor battery charging state.

Progressive forming die
Bednařík, Josef ; Řiháček, Jan (referee) ; Lidmila, Zdeněk (advisor)
This thesis is focused on the technologi of surface forming. It deals with the problematics of metal cutting, bending and drawing. It describes basic construction principles of utilities and requirements they have to meet in order to function properly. Furthermore, the thesis deals with a basic description of the construction and function of progressive forming tools. In the final part of the thesis, there is a debate about differences in manufacturing a semi-finished product depending whether it is a roll of metal which is handed in automatically, or a sheet of metal which is handed in manually.

Control of Magnetic Levitation Educational Model
Bednařík, Josef ; Brablc, Martin (referee) ; Matějásko, Michal (advisor)
The bachelor thesis deals with the modelling and control of the magnetic levitation CE 152 laboratory plant, which is specific in its nonlinearity and unstability. Firstly, all parts of the system are described by mathematical equations, which are the basis of the modelling of simulation model created in MATLAB/Simulink. Estimation of parameters is tackled by using the various of experiments and simulation’s model is validated with the real magnetic levitation system. Main body of the paper is focused on description and aplication of control on simulation’s and real model. It is realized by PID regulator, state regulator and feedforward regulator. In the last part of the thesis, the results are evaluated and compared among the all methods of control.
