Development Module for Radar Safety Sensor in Single-Track Vehicles
Ťavoda, Martin ; Kubíček, Michal (referee) ; Honek, Marek (advisor)
Táto práca sa zaoberá návrhom hardvéru a softvéru vývojového modulu pre senzor bezpečnosti jednostopových vozidiel. Tento produkt je vyvíjaný spoločnosťou ALPS ALPINE Co., Ltd. a využíva radar s technológiou frekvenčne modulovanej postupnej vlny na sledovanie objektov, nachádzajúcich sa za jednostopovým vozidlom. Aktuálna verzia sledovacieho algoritmu dosahuje výrazné nepresnosti pri jazde v zákrute, keď sa nakláňa zorné pole radaru. Predpokladaným riešením je pridanie dát z inerciálnej meracej jednotky do sledovacieho algoritmu. Vytvorený vývojový modul obsahuje práve túto jednotku, vývojové rozhranie, výstupné periférie, riadenie napájania a upevnenie radaru. Zahrnutý softvér implementuje tento modul do existujúceho vývojového prostredia pre radar, pričom sa pre komunikáciu využíva Robotický Operačný Systém 2 (ROS2).

Development of System for Landmine Detection
Šmelka, Martin ; Kubíček, Michal (referee) ; Doležal, Tomáš (advisor)
The Bachelor's thesis will cover a proposal for the construction of a demonstration system designed to discover objects that represent hidden „mines“ in a field. In the first phase, a systém will be designed to simulate the behaviour of the final device using the MATLAB interface. The proposed code will generate a GUI that will simulate the system in the field. After discovering a mine, the assigned cell will be marked, and the location will be signalled to the operator. Afterwards, the design of the demonstrator will be conceptualised and a working prototype fabricated to verify the functionality of the proposal.

Proportional counter measurement system
Horna, Aleš ; Matěj, Zdeněk (referee) ; Kubíček, Michal (advisor)
The thesis deals with gas-filled proportional counters intended for the detection of presence of ionising radiation and its properties. Proportional counters make it possible to find out about the type and energy of ionising particles. The thesis analyses the theory regarding the character of ionising radiation and its detection, describes the measuring apparatus used and the possibilities of verification of counters function. It also deals with the character of signals from the detectors and its imitation. It documents the measurements carried out with various sources of ionising radiation and interpretation of the acquired data, suggests and describes possible improvements of the measuring apparatus.

Load simulator according to ISO 11452 and CISPR25 for a headlamp for EMC testing
Drápal, Ladislav ; Růžek, Václav (referee) ; Kubíček, Michal (advisor)
The diploma thesis with the design of a Load simulator, which will be used during measurements in the EMC chamber. The Load simulator contains a total of five output levels. The diploma thesis solves outputs for directional lights and output for position light. The Load simulator consists of an analog solution of the PWM generator. By assembling a pulse width modulation generator on a solderless field, the basic functionality of the circuit was verified. The measured parameters were compared with the simulated ones. The basic scheme of the PWM generator was expanded with additional components, and an optical control output was created outside the PWM generator. By placing the printed circuit board in an aluminium box, two separate boards were created: one for the power supply and other for the control and performance part. which was not realized yet. The functionality of the circuit was verified by measuring on the PCB, and the waveforms were compared with the implementation on the solderless field. The constructed Load simulator was placed in the EMC chamber, where its resilience was tested through various EMC tests. Finally, the individual results were evaluated, and potential improvements were described.

Hybrid module for industrial localization
Sedláček, Petr ; Fuchs, Michal (referee) ; Kubíček, Michal (advisor)
Tato diplomová práce si klade za cíl návrh hybridního lokalizačního zařízení, které je schopno lokalizace uvnitř i vně budov. Lokalizace uvnitř budov je dosažena pomocí technologie Ultra Wideband a venkovní lokalizace je provedena pomocí kombinace technologie RTK GNSS a PPP pomocí open - source softwaru zvaného RTKLIB. První část textu se zaměřuje na vysvětlení používaných technologií a výběr nejpřesnější technologie pro venkovní lokalizaci. Druhá část se zaměřuje ma vývoj potřebného hardware a software finálního zařízení a na integraci systému pro venkovní lokalizaci do systému pro lokalizaci vnitřní. Výstupem práce je plně funkční zařízení, které je schopné plynulé lokalizace uvnitř i vně budov. Funčnost celého zařízení je dokázána na finálních testech uskutečněných ve vnitřních i venkovních prostorách. Na závěr také práce zmiňuje možná vylepšení celého zařízení, která mohou být v budoucnu provedena.
