This master's thesis deals with eye movement tracking using the Raspberry Pi platform. The theoretical part describes eye anatomy, eye detection and eyetracking. A system in Python programming language was designed in the practical part. This algorithm is able to perform the eye tracking function using the Raspberry Pi platform and the RPi Camera module. The OpenCV library is used for loading and preprocessing images from the camera. A method that detects and evaluates the direction of view after a calibration is available. The accuracy of the program is tested on three vector methods and two target methods for four screen resolutions.

The master's thesis introduces cash register system currently used by Brno zoo and Starezsport Brno. The aim of the thesis was to study and describe above-mentioned systems and hardware they are interacting with, to analyze, design and create new custom cashier system. The first chapter includes the analysis of cashier systems, and overview of selected technologies for developement. Second chapter introduces developement designs and practices. The third chapter contains short system documentation and the last, fourth chapter is devoted to testing basic cashier system functionality.

his thesis focuses on optimization of Linux-based operating system for a accumulator-powered device Raspberry Pi 4. Compared to other devices commonly used in Internet of Things projects, the Raspberry Pi 4 offers many functions within one device. However, the disadvantage is the high consumption of electricity. The aim of this thesis is to achieve greatest possible savings in electricity consumption of the Raspberry Pi 4 device, with regard to functionality of the device as a server for data collection from sensors.

The number of discovered vulnerabilities rapidly increases. For example in 2019 there were discovered 20 362 vulnerabilities. The probability of cyber-attacks realization is high. Therefore it is necessary to propose and implement automated and low-cost Intrusion Prevention or Intrusion Detection Systems (IPS/IDS). This implemetation can focus on home use or small corporate networks. The main goal of the system is to detect or mitigate cyber-attack impact as fast as possible. The master's thesis proposes IPS/IDS based on Raspberry Pi that can detect and prevent various cyber-attacks. Contents of this thesis are focus on description of cyber-attacks based on ISO/OSI model's Link and Network layers. Then there is description of IPS/IDS systems and theirs open source representatives. The practical part is focus on experimental workspace, hardware consumption of choosen detection systems, cyber-attacks scenarios and own implementation of detection program. Detection program is based on these chosen systems and puts them together to be easily manageable.

The aim of the course work is to design and implement a driver for touchscreen LCD display. The premise of the connection the display to the microcontroller using the I2C bus and use MCP23017 circuits. Raspberry Pi B + will be used for communication with circuits MCP23017 via I2C bus. Display TFT_320QVT will be connected to the outputs of extension circuits MCP23017. Part of the display complete is also a touchscreen with XPT2046 controller. Raspberry Pi runs on Raspbian system based on the Debian Linux distribution. The driver will serve to communicate and display information on the screen. The complete will be useable for applications such as selecting settings and show main information on the display.

The aim of this work was to create a communication interface of standard ARINC Aerospace Industry Bus 429. The work has slightly outlined existing solutions, from which it can draw inspiration. Further analysis was performed, analysis of ARINC 429 bus, analysis of Raspberry Pi platform on which the solution will be built, and analysis of selected bus controller HI-3593. After that concept was created, based on concept was created the scheme contains circuitry HI-3593. On the basis of the scheme was created DPS. Next was created software for DPS. In the end of this work was tested abilities to receive and send messages on the bus ARINC 429.

The master's thesis is about a communication element - a hardware module, its design and implementation. The communication is to be maintained between a Linux embedded device and the sensors elements, using the MiWi protocol. The task is part of the IoT project, developed at FIT BUT. Furthermore, the paper describes design of a driver for the module, its likely solution, as well as the very implementation. Finally, the obtained experience is discussed in a summary, along the next step options on how to proceed further with the driver development.

This diploma thesis contains description and realization of smart home system SmartFlat. In the first part of the thesis is analysis of issue and listing of most common variants of home systems with examples. Further into the thesis is the description of parts of system SmartFlat, hardware solution of main unit and there are also explained core software functions of the system. At the end of this thesis are commented results of debugging and testing with real peripheral devices. Conclusion at the end includes brief summary of diploma thesis and commentary of achieved results.

Predmetom diplomovej práce je skúmanie možností realizácie univerzálneho meracieho zariadenia v sieti LTE. Sú popísané základy M2M komunikácie a trendy v IoT. Cieľom práce je nájsť optimálny hardvérový základ, na ktorom následne bude možné konfigurovať LTE modem a získať údaje o stave a kvalite pripojenia k sieti. Následne bude vykonaná séria testov za účelom zmerania parametrov siete a výsledky budú spracované k prezentácii na webovom serveri vo forme grafov.

This thesis examines a development process of a sample tube sorting machine, meant to serve in the university’s scientific workplace. This thesis follows an existing basic motion system. The thesis describes the function of the pneumatic components and their connection to the circuit necessary for carrying and placing the sample tubes. An important part of the thesis deals with designing the connection of a control unit, based on the Arduino and Raspbery Pi platforms. Such connection design consists of connecting the unit to the pneumatical sensors, switches and also the programming of the particular movement functions. Another part covers the ideas of potentional future development of the sorting machine.
