Ultrasonic distance measurement
Klich, Michal ; Krajsa, Ondřej (referee) ; Lattenberg, Ivo (advisor)
The aim of this bachelor thesis is the design and manufacture of a controlling program of equipment for distance measurement using ultrasonic sensors. It focuses on a detailed description of the whole design from the basic properties of the components to the creation of schemes and PCB design. It subsequently describes in detail the development of controlling software of the equipment. The work briefly describes the most important parts of the code. It summarizes all theoretical and practical knowledge gained during the creation of the whole design, it explains the principles of the functions and works of individual parts and it suggests the best possible options of connection of the whole equipment. It also suggests the best possible variants of the entire circuit. The bachelor thesis also describes the microprocesor AVR ATmega8 from the Atmel Corporaton, which controls the entire device, as well as EEPROM memory chip 24LCXXX, SRF05 ultrasonic sensor and communication with the PC via USB using a microchip FT230XS-R.

Receiving and decoding of meteorological signals
Tuchyňa, Juraj ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
The main purpouse of this project is theoretical analyze of data receiving from NOAA (National Oceanic and Atmospheric Administration) meteo-satallites. The project is focused on data processing and decoding them. Received data will be processed and represented. We will use software defined radio (SDR) to help us to understand basic principles of signal processing. We will design conception of receiver in block diagram. Building of functional receiver will be the major part of bachelor thesis.

Application for location of mobile devices
Bojtoš, Michal ; Lattenberg, Ivo (referee) ; Komosný, Dan (advisor)
The bachelor thesis deals with the development of application for positioning of mobile devices. The main goal of the thesis was to create a specific application that can be used to determine positions in the form of GPS coordinates of the device. Device input is private and public IP address. This was achieved by identifying the location of the phone with an integrated GPS receiver, pairing and then transferring output data to the user's mailbox, FTP and SFTP server. Part of the thesis is to compare the location of the device with the data obtained from web applications focused on the geolocation databases. With these data, the application works and provides the results in the form of text and graphical views. Python for Android OS was used to create the application.

Programmable timer configurable via USB
Dresler, Jan ; Číž, Radim (referee) ; Lattenberg, Ivo (advisor)
This thesis describes the design of printed circuit boards and programming AVR microcontroller, that communicates with the digital thermometer Dallas, also with photoresist circuit and RTC. Using sensors and relay allows switching of different devices. The switch allows direct configuration with computer via USB using the auxiliary circuit UART.

Design and realization of the power meter with IoT connectivity
Zagrapan, Ivan ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
This thesis deals with designing and creating working prototype of IoT Wattmeter with option to switching relay. This device can be control remotely with option to read measured values. To reach my goals, I am using open-source designing board, different sensors and modules. I tis possible to communicate with device through Wi-Fi module ESP 8266 and to test LPWAN network I am using SIGFOX, module. To measure current, it´s used simple Hall-effect sensor and all available information’s are displayed on OLED display. To switch the circuit off or on solid state relay was used. In theoretical part of the work, I am trying to explain working principles of every module and source code, which I am using to control these modules. In practical part I created scheme, using CADSoft EAGLE and created functional wattmeter. Whole work is programmed in C++ language using Arduino IDE.

Tools for creating cross-platform applications
Smíšek, Martin ; Burget, Radim (referee) ; Lattenberg, Ivo (advisor)
The goal of the thesis is to analyse the Xamarin.Forms framework and implementing an application based on it. Visual Studio was used as an development environment. External libraries Skia.Sharp, Prism, Acr.UserDialogs, sqlite-net-pcl and rda.SocketsForPCL were used. More than 90% of the application code is shared among all platforms. The application is multilingual and able to keep persistent data. Supported operation systems are Android and Windows 10 covering mobile and desktop devices. The main benefit of the thesis is clarification of the Xamarin.Forms framework principles demonstrated by developed application.

Model-View-ViewModel design pattern in WPF applications
Švikruha, Patrik ; Zeman, Kryštof (referee) ; Lattenberg, Ivo (advisor)
The thesis deals with the explanation of the proposal application according to multi-layered presentation models which describe the distribution of the application layers thereby its facilitating, testability, sustainability and transferability. In this work i focus myself on presentating model for Model-View-ViewModel which is primary designated for WPF application. This presentating model is possible to be built by frameworks used as NuGet open-source package managers or Project templates. In this thesis I focus on framework Catel, which can be used thanks to it´s robustness through all layers of application. The primary output of this thesis is a real application, on which I demonstrate design template with the intagration of framework Catel. I tried to describe whole theory and following process as easy as possible, that even an reader, who has no experiences with designing a multilayer application, could understand it.

Arduino based serial bus decoder
Giertl, Juraj ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
This project deals with possibilities of capturing and decoding data from different serial buses. Then describe ways of automatic recognition of the buses. The project include hardware and software development of device used for capturing data from different serial buses such as SPI, UART and I2C. Characteristics of these busses are described in detail. Device is design as shield to support Arduino boards. The Shield includes four fully isolated inputs and five non isolated imputs for capturing data, Ethernet interface, SD card and two display interfaces witch supports up to ten displays.
