Wireless Tire Pressure Monitoring
Hampl, Tomáš ; Čožík, Ondřej (referee) ; Levek, Vladimír (advisor)
This master‘s thesis describes the design of a system usable for wireless measurement of the tire pressure. The goal is to make a theoretical acquintace with the wireless measurement of a tire pressure. Within the master‘s thesis was suggested device at the block level. For individual blocks have been chosen specific circuits. For the device has been selected the pressure sensor SP100-7AT, the microcontrollers Atmega8 and Atmega16 and the wireless module RFM22. The result of the work is a functional prototype of device including software for microprocessors. Final solution was tested during the experimental measurement.

Miniature Tracking Device
Šťáva, Radek ; Levek, Vladimír (referee) ; Macháň, Ladislav (advisor)
The main theme of this masters's thesis is to design and make a miniature universal tracking device. This device is primarily for tracking asset, pets or people. For detecting the position data is used GPS technology. Data transmission is carried out via the GSM network. The device is technically solved and realized with respect to miniature size, high battery life and with regard to resistance against water, dust and impact damage. It is selected unique design, suitable for hermeticaly closure of the entire facility. Due to hermetic closure there is any buttons, any connectors and the battery charging is wireless.

Laboratory board demonstrates CAN bus
Levek, Vladimír ; Fedra, Zbyněk (referee) ; Frýza, Tomáš (advisor)
The goal of this thesis, is proposal of the laboratory board demonstrates communication by the help of bus CAN. Laboratory boards, controlled with microprocessor, will be send statuses inputs and outputs with each other. Also it will can be transmit and receive messages by the help of the serial port RS-232. With protocol CAN will be send this information: Temperature, Lighting, Analog input 0 - 5 V, Analog output 0 - 5 V, Digital input level TTL and digital output type open collector.

Driver for ultra-bright white LED
Heralecký, Lukáš ; Čožík, Ondřej (referee) ; Levek, Vladimír (advisor)
The aim of this thesis is to study the possibilities of controlling high-brightness white LEDs using circuits operating at high voltages. The job itself is a division of existing light sources and mainly focus on semiconductor technology LED. The following describes the voltage of DC / DC and AC / DC. The work contains a description of the three high-voltage inverters are designed for power LEDs. Finally, it created a draft scheme of the PCB. As a control circuit is chosen ATMEGA 162 microcontroller from Atmel and source for LED diode is formed HV9910 and HV9861 circuits.

Design of the control device for vibrographic measurement
Weiss, Lukáš ; Čožík, Ondřej (referee) ; Levek, Vladimír (advisor)
This diploma thesis deals with designing of the control device for vibrographic measurement. The device is primary used in cooperation with MERCURY Real Time Tracking System. The main task of the device is time-controlled triggering of camera system. In the first step, the summary of basic information about technical diagnostic and vibrodiagnostic is reported. The second part describes vibrodiagnostic measurements with MERCURY system. The third part describes a hardware design of the device and functional blocks and its parameters. Next part provides a simple algorithm of the device operation and a communication protocol. Last part contains measured data of the realized device and vibrographic measurement with laboratory sample.

Lighting control system using a wireless communication network
Levek, Vladimír ; Kadlec, Jaroslav (referee) ; Kuchta, Radek (advisor)
The aim of this thesis is to create and describe the wireless system for lighting control. A part of the work is the creation of modules for switching lighting and the creation of their operating programs. The first chapter briefly describes the way how the lighting control works and contains general requirements for the intelligent home. Further, there is a description of IQRF system, which serves as a wireless platform for the system. Next part of the thesis describes individual modules in terms of hardware and software. One part of the work covers the description of the transmission protocol. The attachment includes a listing of all operating programs for this wireless control system.
