Electronic business card/price tag with wireless communication
Sirůček, Václav ; Sýkora, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
The Bachelor thesis deals with the design of an electronic business card, a portable imaging device that will display data about the wearer (name, surname, phone number and email). Claims are for long-term battery life and remote display of data on an electronic ink display. At work there is a solution for powering the product with a display and its wireless communication with the computer or phone. It also deals with battery status displays, display updates, circuit schematics, electronic business card case design and final realization.

Temperature and humidity monitoring devices with wirelless communication
Hrbáček, Zdeněk ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
The purpose of this work is to design and implement a device for collecting temperature and humidity from bee hive. The system consists of a measuring unit that contains digital sensors and actuators.The system transmits the measured values wirelessly to the parent unit, which displays the data in a suitable format to the user. The user can monitor the hive parameters and use the actuators to adjust the temperature inside the hive. The whole system then operates autonomously according to defined rules.

Identification and Decoding of Wireless Communication Using SDR
Matulka, Filip ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
The goal of this thesis is to create the system that uses concept of software defined radio. This system is capable of automatically identifying the communication parameteres and subsequent decoding of wireless communication. The thesis focus on the wireless system operationg in unlicened frequency band and cosidering fundamental modulation metods. The result is tested on two independent wireless systems that verify ability to automatically identify the communication parameters.

Vision system implementation on Bioloid robot
Ropog, József ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
Tato bakalářská práce se zabývá implementací systému vidění na dvounohý humanoid robot ze stavebnice Bioloid. Systém vidění je složen z bezdrátové kamery, která je namontovaná na robotovi a z řídícího počítače. Cílem této práce bylo zkonstruovat a oživit humanoidního robota, vytvořit systém vidění a bezdrátový komunikační systém. V centru je robot, který pomocí bezdrátové komunikace současně odesílá i přijímá údaje. Tento systém nabízí skvělé schopnosti na další rozšíření.

Security system for family house
Sohr, Martin ; Macháň, Ladislav (referee) ; Jaroš, David (advisor)
This thesis deals with complete theoretical design of security system for a family house, from the selection of technologies, security principles and selection of elements, theoretical suggestions of their placement to practical realization. I this thesis, securing of entry points, such as doors and windows, is done by magnetic contact sensors. Windows are secured also against breaking of glass. Inner space is secured using motion sensors. Further, the function principle of optical latches as secondary securing element of inner space is explained. The designed security system implements a central control unit, which is able to provide status information on all security elements to the host system. IQRF wireless communication operationg in licence-free is used for communication among elements of the security system. GSM SIM9000 module is used for communication with the security system.

Design of the wireless sensor and communication network
Ptáček, Zdeněk ; Šteffan, Pavel (referee) ; Pavlík, Michal (advisor)
The thesis deals with the study of the existing wireless network types, propose and realisation of a dedicated wireless network based on using nRF24L01+ wireless module. The aim is to design a simple, reliable and multifunctional low-cost wireless network. The cellular tree topology and random retransmission delay are used to eliminate cross-talks. Low propagation time is achieved by using ALOHA Access Protocol. Network units cooperate with peripherals in order to measure temperature, humidity, illumination level and other. The power down mode is used to increase duration of battery powered network unit. Practical part of the thesis is focused on creating a computer program to control and set up the network. The network provides a central or autonomous mode.

Advanced Weather Station with Image Transmission
Augustin, Stanislav ; Fedra, Zbyněk (referee) ; Povalač, Aleš (advisor)
The content of this diploma thesis is a hardware and software design of advanced weather station with image transmission. The meteostation consist of two units - outdoor and indoor unit. Outdoor unit provide processing measured values from temperature sensor, atmospheric pressure sensors, rain gauge and windmeter. It also provides processing of captured image and wireless transmission of measured values to indoor unit. Indoor unit should provide comfortable meteostation controlling and visualization of weather situation by web interface.
