Realization of educational problem based on experimental apparatus with cam mechanism
Tomeček, Vojtěch ; Vrbka, Martin (referee) ; Vaverka, Michal (advisor)
Bachelor's thesis is focused on solving educational problem based on experimental apparatus with cam mechanism. The task of the educational problem is to teach students to analyse kinematic quantities of cam followers. The thesis contains general discourse on the topic of cam mechanisms and basic terms definition. This is followed by putting the device into service, eliminating its particular imperfections, analysis of kinematic quantities of various combinations of available cams and followers and definition of methodics of the educational problem. The educational problem itself follows the presentation and commentary of gained results. At last some recommendations for the future modifications of the experimental apparatus are given followed by foreshadow of its eventual future usage.

Datalogger of environmental values
Raichl, Petr ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
The thesis is aimed on construction of solar panel powered datalogger of environmental values. The thesis begins by research of commercial dataloggers. Then the concept of datalogger was created. Then the electronics of datalogger was designed. Datalogger is built as a system driven by microcontroller. The microcontroller reads data from sensors, writes data to memory card and sends data to Czech radiocommunications cloud by LoRa technology. Then the data are resend to MySQL database. Program for microcontroller was made in C language. Configuration of datalogger is done through USB interface by PC application which was created in C# language. For visualisation of measured data ASP.NET Core application was created.

Passive sensors for detecting instantaneous stress and strain values
Jašek, Petr ; Kandus, Bohumil (referee) ; Podaný, Kamil (advisor)
Technical measurements are an indispensable source of information in the technical fields. Due to the computer processing it is necessary an electrical signal as the output of the sensor. The field of measuring techniques of non-electrical quantities comprises a wide range of various sensors. Passive sensors represent an important group, into which resistive, inductive, capacitive, magnetic and ionization sensors are arranged. Basic findings of measurement are presented, and particular kinds of sensors, their functional principles, application examples and evaluation of their properties are described in the thesis.

Design and construction of MIDI interface for sensor strings
Korytář, Matěj ; Přikryl, Lubor (referee) ; Jirásek, Ondřej (advisor)
This work focuses on problematics of MIDI converter design and construction for cimbalom. There is briefly described acoustic musical instrument in terms of tone creation and construction. Further is discussed possibilities of string sensing or other ways to capture performance. In the following chapter is described MIDI protocol in terms of history, interface and types of transmitted messages. There is also said requirements for converter's chip and way to connect it. Further is described a method of converting signal from sensors and following coding to MIDI protocol including used program with detailed specifications. In conclusion is discussed several future extension.

Implementation of smart water measurement technology into small municipal waterworks environment
Klučka, Tomáš ; Zubíček,, Vojtěch (referee) ; Ručka, Jan (advisor)
The diploma thesis describes the actual situation of smart water metering, an overview of water meters suitable for remote data reading and individual components for application of remote data transmission including transmission itself. The thesis also contains the characteristics of available wireless data communication technologies and detailed solutions according to two companies specializing in remote transmission of water meter data. Subsequently, the pilot projects of large water company are presented, including practical findings. The practical part deals with the implementation of smart water metering in three specific municipalities, including a description of the area of interest, water supply system specification and possible limitations, the recommended technology, the requirements for putting in into operation and the pricing of technology and services according to two specialized companies. Finally, the possibilities of other using of smart water meter technology are discussed.

Three dimensional force sensor
Černý, Hynek ; Krejčí, Petr (referee) ; Houfek, Lubomír (advisor)
The bachelor’s thesis dealt with the design of a force sensor, which was supposed to do measurements of forces in three axes independently. The another required output of the work was creation of drawings. The design and optimalization of shape and dimensions of the sensor was made mainly in program called ANSYS. An important part of the work was the expression of final relations for the calculation of forces both analytically using simple elastic strength and the numerical finite element method. The last part of the work was an experimental measurement, which was supposed to verify accuracy of both methods for forces expression and also correct functionality of the sensor.

Chassis Electrical Systems
Slaběňák, Patrik ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Travelling by bus is very extended in present and safety return home is a wish of every passenger. Outcome of this bachelor work is a survey of the most used stability systems, used in cars and facilitating the work of drivers in critic situations. Among others, this work contains the survey of powers acting on a vehicle during the ride. This powers influence impending slippery road on aggravated adhesive conditions. Individual systems are described attentively and supplemented by illustrating pictures, which near this issue and facilitate the real idea of functionality. At the conclusion of this work is mentioned the theoretical suggestion for practical exercising of a subject automobile electrotechnics and also a referring is mentioned to my continuation in this dissertation.
