Industrial Tester for Photometric Values of LED diodes Used in Automotive Signal Lighting
Gaži, Dominik ; Froehling, Kenneth (referee) ; Baumgartnerová, Alena (advisor)
V posledních letech zažili světlomety v autech obrovský technický rozvoj, který se podílel na jejich současné složitosti. Aby řidiči i zákazníci byli spokojeni, je využíváno různých technologií pro neustálé dosahování účinnějších a bezpečnějších světelných zdrojů. Společnosti usilují o minimalizaci ztrát ve výrobě ve snaze šetřit životní prostředí a konat ekonomicky. Tato práce se zabývá výzkumem osvětlovací techniky a návrhem jednoduchého a efektivního zařízení pro testovaní chyb LED plošných obvodů ve světlometech, to vše za účelem minimalizace strat. Dalším cílem je výzkum možností konstrukce takového zařízení z technologického hlediska.

The tester semiconductors device
Čala, Martin ; Čejka, Miloslav (referee) ; Havlíková, Marie (advisor)
Theoretical part of the bachelor thesis describes ATE systems focused on electrical tests of semiconductor diodes. There are also described key features of measured devices. In the practical part of bachelor thesis, there are described analysis made before design and realization own tester capable of recognizing unknown semiconductor diode and displaying selected static and dynamic parameters via text and graphical output. Whole system is based on Elvis II+ platform. Controlling application is made using MATLAB.

Testing and charging of accumulator cells
Sršeň, Jan ; Kubánek, David (referee) ; Lattenberg, Ivo (advisor)
Direction of the master's thesis is design and construct electronic device for testing available accumulators. Than there are in detail subscribe some metods of charging cells and their right usage to select type of cells. Also eventually problems that can become if the choice is false. Next part contains description of principles as several type accumulator works and their loading characteristic witch are important know for choose the best testing way. The most important knowledge is detection of stop point charging when accumulators are charged and following charging can be dangerous. Because there are more methods to detect this point so in thesis are overwrite. The most important part is design of tester. That is mapped to more segments witch communicating together. Controller part of intelligent tester contains ATmega128 microcontroller so there is present a passage of program code. Last section of master's thesis describe a physical consruction and explain division for smaller parts and hole process of tester function.

Reconstruktion of road simulator.
Stodolák, Michal ; Roupec, Jakub (referee) ; Mazůrek, Ivan (advisor)
This bachelor’s thesis is dealing with reconstruction of drum road simulator, which is placed in laboratory of The Institute of Machine and Industrial Design. The first part is attended to basic dividing of road simulator. The second part contains description and analysis of the current machine. In the next part is an analysis of chosen variation and their construction. The last part of thesis is attended to the lightening of the load wheel in period, when the test doesn’t run.

Two-chamber Tester for Cordless Drills
Kabátník, Václav ; Benešl, Tomáš (referee) ; Jirgl, Miroslav (advisor)
This thesis deals with the design and subsequent realization of a bicameral tester for cordless drills. The tester will contain with two chambers in which the device will be tested. Part of the solution is the description of the parameters of the tested devices and the design of the tester concept. In addition, the thesis deals with the design of a mechanical structure that will test the equipment in both chambers and then design and realization of the relevant electrical equipment including the electrical switchboard. The thesis describes the Mosaic development environment for development of the PLC program according to IEC 61131-3. In this environment, control software has been created, which is described in its chapter. At the end of this work are enclosed images confirming the implementation to the real system and its functionality
