Laser Plotter for Cutting Steel Plates
Dokulil, Marek ; Šimek, Václav (referee) ; Crha, Adam (advisor)
This diploma thesis is divided into two main parts. The first section is dedicated to the history and development of the laser technology. The second part describes all individual types of laser technology which are used in the industry nowadays. The next section follows with the research of various laser devices which serve mainly as a cutting tool. This knowledge gathered in the previous part was used to create the next part including the own conception of the machine. The second half of this diploma thesis deals with a research of software available at the market today. Eventually, after summarizing the characteristics of each software, the new concept and implementation of own software are made. In the final section, there are mentioned the possible extension and available upgrades. The reader should be able to create his/her own conception of the laser device and software after reading and understanding this paper.

System for contactless ultrasonic measuring of edema
Zahradníčková, Ludmila ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
Determination of the extent and state of a limb edema is based on information about its current volume. There are a number of methods for volume measurements. The theoretical part of this semestral thesis discusses the etiology, classification and principles of volume measurements and basic information about ultrasound and stepper motors. The practical part consists of a design of own device for a contactless limb volume measurement with ultrasonic module. It consists of a code for a microcontroller which controles the whole system including the computational operations and a real model of the system.

Design and prototyping of electronics for manipulation platform
Ondryáš, Adam ; Andrš, Ondřej (referee) ; Hadaš, Zdeněk (advisor)
Tato diplomová práce je součástí projektu, na kterém pracují dva studenti. Cílem projektu je navrhnout a realizovat řídicí systém pro polohovací platformy. Tento řídicí systém umožňuje napájet polohovací platformy baterií a také je bezdrátově řídit z PC. Projekt se detailně zabývá koncepcíj ednotlivých funkcionalit řidicího systému, návrhem a prototypováním hardwaru řídicí jednotky, návrhem firmwaru pro řidící jednotku a návrhem softwaru uživatelského prostředí. Částmi projektu, kterými se zabývá tato práce, je koncepce jednotlivých funkcionalit a návrh hardwaru řidící jednotky. Hardware řídicí jednotky byl v rámci práce navržen, vyroben a úspěšně otestován. Výstupem práce je tedy vyrobený prototyp řídicí jednotky, který lze v rámci projektu dále rozvíjet.

Design of motorized optical system used for focusing of a laser beam
Zobač, Evžen ; Novotný, Karel (referee) ; Novotný, Jan (advisor)
This diploma thesis deals with the structural and optomechanical design of automatization of focusing laser beam for a remote laser spectroscopy device. The chosen solution uses an active rangefinder and a rotary unit to control the change of the focus plane of the device's optic system. The dependence of the focus plane’s change on the shift of lens in the focus plane was practically measured. For proper control of the rotary unit, this dependency is needed. Structural parts were made based on the created drawing documentation. The structural parts were mounted in the existing assembly of the device together with the purchased components. The proposed solution enables a change of the optical system, for example, in order to obtain a more appropriate range of focal planes.
