Realization of the optical source with superluminescent diode
Juráň, Jakub ; Levek, Vladimír (referee) ; Čožík, Ondřej (advisor)
This bachelor’s thesis describes design of the optical source with superluminiscent or laser diode. Firstly, the problems of optical sources in the form of laser diodes (coherent light sources) are analyzed. The thesis contains a description of the realization of circuit that includes blocks of temperature and current flow control, block of the power management and the control block. The electrical circuit is divided into the functional modules, their functionality is explained in details. It also includes description of the software designated for controlling of the circuit’s functions.

Home wireless control system for electrical appliances
Sedlář, Tomáš ; Levek, Vladimír (referee) ; Čožík, Ondřej (advisor)
The bachelor's thesis deals with the hardware and software realization of a wireless system for controlling electronic devices in the household. Firstly, the work briefly describes automation in the home environment. Next, the general structure of the designed system is described more closely. Consequently, the project discusses the design of the master and slave device of this system including the suitable components selection. The following chapter deals with designing the printed circuit boards for each device. Finally, there is an outline of the proposed software for this system.

Three-way control valve in industrial environment
Vozár, Viliam ; Čožík, Ondřej (referee) ; Levek, Vladimír (advisor)
This work deals with the design, realization and testing of the system for regulating the temperature of the water in an industrial environment using three-way mixing valve. This system can work autonomously, but also can be controlled by a superior control system. Created temperature regulation can be adjusted and controlled by a computer using control software.

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.
