Electronic Platform of the System for Eye Retina Acquirement
Malaník, Petr ; Hájek, Josef (referee) ; Drahanský, Martin (advisor)
This work deals with a control of the platform which is used for scanning of the eye retina. The purpose of this platform is the three-axis motion, camera sharpening and a controlling of LEDs to illuminate the eye. Within this is solved the issue of stepper motor control, LED brightness control and communication with a microcontroller. Part of the thesis is the programming of STM32, i.e. 32-bit microcontroller of STMicroelectronics in C/C ++ using HAL abstraction layer and Python 3 demo application.
WETTABILITY OF PCB SURFACE FINISHES
Minář, Jan ; Jana, Toulová (referee) ; Starý, Jiří (advisor)
This bachelor’s thesis with measuring of wetting characteristics by the wetting balance method for samples of different surface finishes from the firm Gatema. It deals with influence of the isothermal aging and reflow processes on wetting characteristics of surface finishes ENIG, HAL and immersion tin. The influence of intermetallic layer on the overall wettability is studied in case of the surface finish of immersion tin. Also deals with the wettability of the nickel layer, after stripped off gold, in case of the surface finish of ENIG.
HAL Technology and Selected Parameters Influence on Quality
Jakub, Miroslav ; Jana, Toulová (referee) ; Starý, Jiří (advisor)
Bachelor thesis describes and deals the problems of printed circuit boards production. It focuses on issues of process of lead – free HAL and influence of selected parameters on quality in production process GATEMA s.r.o. in Boskovice. Bachelor thesis contains analysis of PCB using microsection, optical microscopy and a sample of defects created during this process. Bachelor thesis presents on the test boards quality of solder mask developing, evaluates flux contamination with water, residual water on the PCB and it compares the PCB delay in liquid solder. It also determines the limit of non defective cover with the solder and determines the typical thickness of solder mask on the Cu pads and the ratio between the width of font and solder mask thickness.
Solderability of PCBs Surface Treatments and Environmental Influences
Jičínský, Jiří ; Zatloukal, Miroslav (referee) ; Starý, Jiří (advisor)
This bachelor’s thesis deals with the properties of surface treatment of printed circuit boards. The main purpose of this work is to compare the OSP coating applied under laboratory conditions and the technological procedure established in the company ČEMEBO Blansko. Samples of ENIG, immersion tin and OSP compare due to their critical aspects. In the practical part, the samples au exposed to various elements of nature according to ČSN EN 60068-2. The surface wetting balance method will be used for better comparison and evaluation.
File Synchronization on 3 or More PCs
Nykrýn, Lukáš ; Michlovský, Zbyněk (referee) ; Jurnečka, Peter (advisor)
This document descripes the design and implementation of application for file sharing between multiple computers using an external drive. Application can be run on GNU/Linux and MS Windows. In Windows application performs synchronization at regular intervals. Under GNU/Linux offers extra choice to watch the status of files and immediately synchronize file after change. The whole system monitors and cares for all possible collision states of files that can arise.
USB Host with PIC Microcontrollers
Kučera, Pavel ; Janoušek, Vladimír (referee) ; Hanáček, Petr (advisor)
The aim of master thesis is implementation of USB host in a microcontroller PIC. The thesis contains description of ways of peripherals to computer connections with detailed description of USB bus. There are also discussed several approaches in implementations USB host for embedded systems. A concept of layered USB host system is designed on the basis of analysis of the state of the art. Finally, the designed system is implemented in microcontroller. Resulting firmware of development kit is tested on real USB device.
Tools of Economic Regulation to Protect the Environment in the Field of Energy in the Czech Republic
Melichová, Jana ; Vopátek, Jiří (advisor) ; Černý, Jaroslav (referee)
This thesis deals with instruments of economic regulation related to environment protection in the field of energetics. It surveys selected instruments in the form of ecological taxes and Emission Trading System. It clarifies the origin and development of these instruments and their integration into the legislation of the Czech Republic. The major aim of the thesis is to analyze the impact of ecological taxes and trading with emission permits on management decisions of a company.The analysis and calculations have been carried out in a real enterprise. I have tried to prove how the System of Emission Trading impacts on the management decision and strategic goals of a company due to further development of the EU System of Emission Trading, its changes as well as changes in production of a company.
