Controlled heating of Composite Material
Fajkus, Martin ; Macháň, Ladislav (referee) ; Šteffan, Pavel (advisor)
The supposed thesis considers problem of heating of composite material for outdoor application. Basement of thesis is analysis of submitted sample of composite material. Measured values of composite material were compared and evaluated and than acceptable samples were choosen for next application. Part of thesis is creation of measuring software for analysis of sample. Other part of thesis is realization of equipment of control unit for heating of composite material. Control unit makes it possible to regulate heating and to set up parameters from computer.

The System for Controlled Heating and Roller Blinds in the Building
Brudný, Tomáš ; Macháň, Ladislav (referee) ; Šteffan, Pavel (advisor)
The object of this project was to develop a device, which would by use to coordinate or control device wireless. The system divided to several independent devices, which assure high comfort for the user. The basic unit contains of touch panel which allow the user to control the system. The second unit is used for communication the system with GSM net. The third unit is used to coordinate the system from a PC. This unit makes possible data collection and their evaluation. This unit can as well control and coordinate any devises in the system. Part and parcel of this system are units which are used to drive the end consumers. The hole system is powered from a instead powers supply which is managed from a microprocessor. These devices make it possible, to the system to work without line voltage. The system is designed modular, so in the future it is possible to expand the system of others peripherals.

Construction of On-board Computer for Motorcycle
Rulc, Martin ; Široký, Daniel (referee) ; Šteffan, Pavel (advisor)
This work deal with system design and implement of Trip computer for motorcycle serving as information element of speed and fuel consumption motorcycle. The general aim is design of device with graphic display that shall represent measured values of speed motorcycle, rpm of motor, onboard voltage, charging current, motor temperature and ambient temperature. All measuring data will be saving on memory card. For easily tracking in system menu will be used touch panel on graphic display.

The controlled heating of composites materials
Fajkus, Martin ; Havlíček, Tomáš (referee) ; Šteffan, Pavel (advisor)
Expected work solves problem of controlled heating of composite material for outdoor application. Basement of work is analysis of submitted concrete specimen of composite. Then I find out influence of direct and alternating voltage on submitted specimen and I choose method of measurement. Whereas I chose correct method of measurement, I could measure all specimens. From comparing I chose specimen of composite material, which are suitable for a next application. For chosen specimen of composite material I designed control unit for heating and tempering. The control unit was designed according to their parameter.

Universal Tester of Tyco Fire panel
Vítek, Ladislav ; Kalina,, Emil (referee) ; Šteffan, Pavel (advisor)
This work is aimed on design of a device for testing of fire detectors and various components of fire detection system, communicating with the fire panel over a fire bus or a loop. The device generates voltages, supplying the detectors, as well as communicating over the bus generating communication waveforms and performing detection of responses measuring voltage and current on the connection. The loop signal is processed by the developed unit and data or result sent to a PC utilizing USB or RS232 connection. All the parts of the equipment are galvanically isolated to the loop circuit.

The system for administration keys trough the using RFID
Veselý, Aleš ; Šteffan, Pavel (referee) ; Pavelka, Ondřej (advisor)
This thesis dealing with description and system design for administration keys trough the using RFID technology. The main task of this thesis is create a complete controlling algorithms for this system include operating program for platform Windows. Practically output of this thesis is system controlled by microcontroller, which make a decision based on authorisation whether man in question have an accession to the system and which keys he can take.
