The energy independent flow meter with remote reading
Šindelář, Jindřich ; Růžek, Václav (referee) ; Dřínovský, Jiří (advisor)
The thesis is focused on the design of a self-powered sensor for measurement of water flow rate and temperature in water pipelines. The key block of this thesis is the construction of an electric generator powered by excitation with turbulent flow. The generated voltage should power the sensor's circuits and allow water flow rate measurements. Throughout the development, three prototypes of generators powered by turbulent flow were created. Turbulences were not created by an insertion of a bluff body but by inner geometry of the pipeline elements. Maximum power of 10,66 uW was generated at flow rate of 8 m3/h. Afterwards, a prototype of water flow rate and temperature sensor was assembled. Energy self-sufficiency of the device at common flow rates was not achieved using the chosen procedure. The designed flow rate measurement method is suitable for an approximate flow rate estimation.

Design and construction of guitar multi-effects
Šindelář, Jindřich ; Kratochvíl, Tomáš (referee) ; Petržela, Jiří (advisor)
This thesis focuses on design of electronic circuit which combines several effects for electric guitar. These effects are switchable to achieve relatively wide range of sounds usable in different music genres. Each chapter of this text describes function and design process of single subcircuit. In the summary of this text are written up sound characters of effect in particular modes. Attachments contains the results of design needed to build a functional prototype of the whole circuit.
