Flight Timer in Ultramicro Aircraft/Helicopter
Široký, Adam ; Mlích, Jozef (referee) ; Zemčík, Pavel (advisor)
This thesis deals with the development of embedded system for ultra light airplanes and helicopters. The aim is to design a system which would allow to measure and record the length of individual flights. It is therefore an onboard electronic diary which should facilitate and streamline the administration associated with sport aircraft operation. The base of the system is created on microcontroller of the MSP430 family by Texas Instruments. A reader will be offered the used hardware, the system design, the way of function and the possibility of using of the suggested system.

The use of Electrical Properties of Composites with Modified Cement Matrix
Macháň, Ladislav ; Husák, Miroslav (referee) ; Sýkora, Jiří (referee) ; Šteffan, Pavel (advisor)
The dissertation thesis is focused on practical use of composite material with modified cement matrix. Especially the area of electrical behavior of composite materials in use has been examined, for strain sensing material. The experimental part solves the problematics of corrosion of carbon and metallic materials in alkaline environment of the cement matrix. The physical design of the sensor and its fabrication using functional composite cement material have been described here. The thesis has also discussed defining the influence of temperature change and humidity change on the change of electrical parameters of integrated sensors. An important part of the thesis is the area of evaluating a series of measurements of electrical parameters under dynamic loading. The thesis analyzes designed measurement method in detail, being suitable to determine electrical properties of cement composite materials including the construction of a monitoring system that enables practical application of sensors in complex structures.

USB Measurement Module for Virtual Instrumentation
Hanuš, Ivan ; Beneš, Petr (referee) ; Havránek, Zdeněk (advisor)
The objective of this thesis is design of the universal USB measuring module for virtual instrumentation. The module is connected to PC via USB interface. The module have analog inputs and analog outputs. The inputs have some switchable ranges, adjustable high-pass and low-pass fiters. Also the module have the digital input-output unit with 8 channels with configurable data direction and voltage level. Physical layer for digital serial interfaces SPI/UART and I2C is also part of this unit. The module is able to communicate with LabVIEW enviroment. The teoretical part contains survey of the commercial USB modules for data acquisition and generation from various manufacturers with its basic parameters. Some selected modules are described in detail. Furthermore the thesis deals with possibilities of connecting the USB module with the LabVIEW enviroment. The practical part deals with the design of input-output circuits and with design of the module itself. Furthemore, tho communication protocol, utility library and demonstration LabVIEW software are described in this part. At the end of this part, there are results of verification measurements. The result of this thesis is completed universal USB measuring module with utility library and demonstration program.

GSM monitoring system for elderly poeple
Ďurík, Maroš ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
The work deals with design of system for monitoring elderly people. The final product of this thesis will be used to ensure protection of old person´s health. The device will also remind water regime, taking of medicine, measure gas concentration and it will make an emergency call or send an emergency SMS. It will inform an old person about time and date and it will also be working in case of power fail.

Measurement of Symmetric Cipher on Low Power Devices for Power Grids
Fujdiak, R.
The symmetric ciphers are often used in low power devices for its low requirements. This article provides a measurement of AES-128 cipher, which should be used for secure communication in power grid (smart grid) networks. We are using as low power devices the microcontroller MSP430 from Texas Instruments. These measurements, deal in this article, should help with implementation of the whole concept of encryption. Concretely, it shows the space left for the other algorithms (as for example elliptic curves algorithm for key distribution, communication protocols etc.)

The system for regulation of the environmental conditions in the aquariums
Janda, Josef ; Jaroš, David (referee) ; Macháň, Ladislav (advisor)
This thesis project describes the design and construction of an automated system for maintaining live conditions in aquarium. The main purpose of the system is to automate certain procedures and to ensure control of important environmental parameters of artificial breeding of aquarium animals and plants. The device regulates lighting, temperature, CO2 concentration and other parameters. The LCD with touch screen is used to system control and to display measured values.

Design digital optical output
Kubáč, Stanislav ; Beneš, Petr (referee) ; Klusáček, Stanislav (advisor)
This work descibes general principles of measuring the alternating current and voltage using conventional and unconventional sensors.This work shows specific parmeters conected with principles of the measurement, advantages and disadvantages of individual measuring procedures, types of output signals, precisions, limitations, ways of power and so on. Part of the work is to find optimal measurement procedure, which can be aplicated to practical measuring of alternating currents and voltage. Main part of the work concerns the realisation of optimal method of measuring alternating current.
