Liquid Crystal-Based Computational Platform
Klázar, Jakub ; Šimek, Václav (referee) ; Bidlo, Michal (advisor)
This work explores the possibilities of computations in a liquid crystal, specifically focusing on the logical operations. The text focuses on the design, build and use of a platform for performing experiments on computation in a liquid crystal. The platform is a device to which an LCD display can be connected as a experimental liquid crystal and experiments can be controlled from a computer through this platform. Experiments use, among other things, evolutionary algorithms. Further, the paper deals with the execution of experiments, discussion and processing of results and then creating conclusions of it.

Emulation of Character-Based LCD Display Using E-Ink Technology
Rusín, Tomáš ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The aim of this bachelor thesis is to design a simple printed circuit board interconnect. The board is planned to be equipped with a microcontroller that will receive communication signals originally intended for LCD character displays. The communication may be parallel or serial, in the form of SPI and I2C type interfaces. These signals are planned to be received and converted to E-Ink display signals. That display will show information in the same format as it was designed for LCD displays. The E-Ink display replaces LCD displays without the need of changing the original library or the original communication interface. This method of replacement is suitable when a LCD character display is destroyed and a suitable replacement cannot be found, or when the E-Ink display is more suitable.

Finger Position Tracking in 3D Space
Hegr, Miloš ; Šimek, Václav (referee) ; Malaník, Petr (advisor)
The aim of this work is to create a universal system for measuring data describing position in 3D space. This paper provides a theoretical overview of position description in 3D space and shows the possibilities of position reconstruction from sensor data. It gives a closer look at the RingOne hardware device, and finally proposes and implements a system for finger position reconstruction using this device. This system consists of the firmware for the RingOne device, a C language library allowing easy communication with the measuring device and a protocol defining the way data is transmitted and how the measuring device is configured. This work is also complemented by a modified Spacenavd driver for easy presentation of the measured data.

Building Heating System Controller Using Zigbee
Mičulka, Lukáš ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This thesis is focused on the design and implementation of heating controller system of the model house. In terms of design is the emphasis on simplicity, efficiency and scalability. Implemented heating controller system includes a central controller unit and modules that are placed around the model house and can perform several functions - temperature measurement, control actuators or remote parts of the wireless link. This thesis describes the complete development from the initial system design through assembly of all elements of hardware, firmware implementations for each module type and a control program running in the control unit. It also describes the communication between system elements. Suitably chosen solution combines wired and wireless connections, depending on how it is ideal in terms of the model house. The whole system of functional prototypes was tested and the results were summarized in the conclusion.

GameBoy Advance Emulator for Mobile Platforms
Vilímek, Hynek ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
The GameBoy Advance console was released by Nintendo in 2001 and it has experienced phenomenal success during its existence. It used to control the majority of the market at one time and partly due to this it has become synonymous with portable gaming consoles. This popularity was gained especially thanks to the games developed for it. They have become so popular that even today there is a demand for them. These games, however, are not played on the original consoles but on today's mobile devices. And since current mobile devices are technologically very different from the console, it is necessary to run these games via an emulator.

Intelligent Access Terminal Using ESP32 Platform
Pomykal, Šimon ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The aim of this thesis is to design cheap intelligent access control system based on esp32. This system is designed for use in family houses, flats, garages, gardens etc. The designed system is composed of access control terminal module which uses fingerprint reader to authenticate people and of camera modules which monitor the area of entry These modules are connected to cloud using AWS IoT Core. Another part of the system is a cloud application which evaluates data from the system. The acces control system is meant to be part of a home security system, but can be used independently to some extent.

Design of Sensor Modules for ZigBee Wireless Network
Tichý, Andrej ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The purpose of this study is to contribute to spreading of the global phenomenon IoT and to create a sensory network. In my study I focused on the development of active and passive modules using the IEEE802.15.4 standard based on the ZigBee protocol. When creating my modules I was using the micro-controller CC2530 by Texas Instruments having the processor platform 8051. To implement the communication firmware for sensory modules I used the Z-Stack 3.0 implementation. The main communicator uses the CC2530 micro-controller as ZigBee network preprocessor and miniPC raspberry pi as ZigBee application processor. As a part of this study I created an active module that enables to control the relay; an RGB led strap using the PWM modulation and also the electric current measurement using noninvasive sensors. I also created a passive module including sensors BME280, TSL2561 and DHT11 to measure the air pressure, temperature, humidity and light intensity. Furthermore I created an universal module that makes easier the creation of new prototypes. Not least I created all-purpose raspberry mini-module. The relevance of this study is given by creation of module prototypes using the ZigBee protocol. Special value within this study has the the mini-module for Raspberry Pi which can be used in various roles within the ZigBee topology.

Home Security and Monitoring System
Valach, Lukáš ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The thesis elaborates on an implementation of wireless home security system. The wireless communication utilizes IEEE 802.15.4 radios and ZigBee communication protocol. The beginning of the thesis provides specification of the intended system followed by an evaluation of usable energy harvesting solutions and later by consideration of single board computer systems suitable for implementation of the control node of the sensor network. The rest of the thesis describes design, implementation and testing of particular components of the security system. Conclusion evaluates the achieved goals and offers suggestions for future work. The end products of the thesis are physical devices implementing wireless sensor nodes, control unit of the security system as well as a graphical user interface for the system management.
