Design of Portable 3D Scanner
Štigler, Jaroslav ; Rubínová, Dana (referee) ; Sovják, Richard (advisor)
The topic of this bachelor‘s thesis is design of handheld 3D scanner. This scanner belongs in the higher price category. This thesis deals with problems like long working time, watching monitor during scanning, versatility and safety measures from mechanical damage. Ergonomic solution is also very important. This design is based on a simple and functional shaping. Shaping and color solution corresponds with its use in industry. This scanner also can be used in other fields (for example: medical sector, design, archeology, etc.).

Altitude meter for RC models
Beneš, Jan ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
Altimeter measures atmospheric air pressure and counts actual model altitude from it. Then sends data to ground module, which shows them on display. Ground module contains USB interface for connecting to PC. It enables upload of flight data and opportunity to show them in graphical representation.

Unit for wireless transmission of electrical energy
Jelínek, Aleš ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
The aim of this work is to prove the practical applicability of the concept of contactless energy transfer using induction coils. The first part deals with the mathematical model and theoretical proof of the concept being able to work in practice and describes the process of detecting resonance of receiver circuit on transmitter side. Next chapter describes hardware solution of the experimental prototype. The last part contains measurement results of a coupling coefficient of coils and discusses performance and notable features of the prototype.

Modelling and simulation of communication system receiver for unmanned aircraft
Hoferek, Jakub ; Prokeš, Aleš (referee) ; Maršálek, Roman (advisor)
This diploma thesis deals with the simulation of the radio communication system for satellite control of unmanned aircraft, namely the command and control communication link – the forward link. The aim of the thesis is to create a simulator in the Matlab environment. The simulator includes a model of the transmitter, radio channel and receiver. Four-state CPM modulation with partial response and filtered symbol shape is used. The radio channel performs noise, frequency Doppler shift and time delay to the received signal. Subsequently, in the Acquisition Unit, the Doppler shift and time delay are detected and compensated. At the end of the thesis, the simulation results of the presented model are presented in the form of graphs đť¸s/đť‘0.

Wireless IR sensor for space intrusion detection
Možný, Radek ; Krajsa, Ondřej (referee) ; Škorpil, Vladislav (advisor)
The bachelor thesis deals with design of wireless space breach detection sensor using sensor HC-SR501 and communication module SI4432. In thesis emphasis is on design of device with as low power consumption as possible using sleep modes of microprocessor Atmega328. Thesis includes desighn of temperature measurement, battery state measurement and subsequent broadcasting of gained information to receiving base station. Task of basae station is to evaluate information and among other things decide whether or not is guarded space breached. Two sensor network is further elaborated when sensors are sending periodical notification, person detection alarm, sensor manipulation alarm or warning about low battery state. Base station has regimes guarded and unguarded .

Wireless sensor network
Šťáva, Radek ; Šteffan, Pavel (referee) ; Pavlík, Michal (advisor)
The main theme of this work is to design and make a modern network of wireless sensors, when the main used circuit in the sensor module and the receiver module is microcontroller Texas Instruments CC430F513x. Care is taken primarily at very low power of sensor module for long battery life when on battery power. It is also emphasis is on reliability involvement of miniature size, expandability and high precision modules of basic sensors.

Wireless OBDII-Bluetooth Interface
Bezdíček, Jan ; Šimek, Václav (referee) ; Bartoš, Pavel (advisor)
The goal of this bachelor's thesis was to design an OBDII interface, which would have been able to communicate with a PC through Bluetooth interface. Designed wireless interface is able to diagnose all OBDII equipped vehicles, but the vehicles have to communicate by some of the supported protocols. It is possible to communicate with a vehicle using a software application or by simple commands in data terminal as well. Main parts of the device are a proprietary ELM327 microcontroller and an industrial Bluetooth module. The built-up device has been tested and it is able to display right values of vehicle sensors and to operate diagnostic trouble codes as well.
