Remote control of targets
Tkáč, Stanislav ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
The task of this work is to make a functional device, that is intended to close only one of several (38 to 55) of electromagnetic valves. Which valve is going to be switched is elected either of the push-button keypad, or from a PC via RS 232. Equipment must be made using one or more PIC processors.

Communication of a Measuring Device with a Computer – Laboratory Experiments
Cigánek, Jan ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
This project deals with the programme for automated measurement. Project describes main theory advices and possibilities of building programme with language C++. It shows complication in communication of PC with measurement devices and it describes programme commands. This work includes programme, solution, structure with examples of the algorithm and source code. The designed control programme has been applied for automated measurement of frequency characteristics of low-pass and high-pass filters with the analogue multiplier AD 633 using the programmable DC power supply Agilent E3631A, the digital multimeter Agilent 34411A or digital storage oscilloscope Tektronix TDS 1012 and generator Agilent 33220A.

Thermo-electric solar generator
Kočvárek, Ondřej ; Jakubová, Ivana (referee) ; Gregor, Jan (advisor)
The introduction of this work is devoted to the description of physical principals and condtruction of modern semiconductor thermoelectric transformers. This work describes thein basic characters and the most commonly used materials for thein production. Further, it mentions the basic principals and physical effects that describe the thermoelectric conversion of energy and the nondestructive method for establishing the basic material characteristics of thermoelectric transformers. The substantiv part of this work is the measuring of the material’s characteristics of the accessible thermoelectric elements through the medium of experimental measuring network. The optimal construction of thermoelectric solar generators used for individual thermoelectric elements are designed based on the taken measurements and the evaluation of material’s characteristics of the observed thermoelectric elements.

PIN Modulator and Attenuator - laboratory experiments
Kaller, Ondřej ; Jakubová, Ivana (referee) ; Svačina, Jiří (advisor)
Purpose of this bachelor’s thesis is making conception of laboratory work “Amplitude modulator and attenuator with diode PIN“, what was alternative work measure in subject BSES on other sample. For this laboratory work was chosen amplitude modulator of company Hewlett Packard HP - 8732A for its advantage properties, especially easy manipulation with respect to coaxial connection of microwave signal. Work contains partly theoretical summary principles activity of diode PIN, partly it introduce their applications, especially in amplitude modulators directed of reflex reducer. Next there are documented results of single measures servant for ensure check needed properties modulator HP – 8732A. The main part of this work is proposal several points of measure together with introductions for operating devices, proposal form of measure protocol and it’s example. Final point is idea of possibility usage this modulator in power stabilizer.

Communication Adaptor for Data Acquisition System Hardware and Software Design
Kašpar, Petr ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
The aim of this bachelor thesis is to create adaptor with microcontroller for data acgusition system. Function of the device is to receive serial asynchronous string of ASCII characters which was send from ultrasonic thickness gauge. Baud rate of transmittion is 2400Bd. Transmittion is realized according to RS-232 standard. Part of the string contains numeric information about value which was measured by thickness gauge. This numeric information is in microcontroller multiplied with corrective constant and decimal point in result is placed to right position. Corrective constant is stored in EEPROM memory. After that adaptor transsmits data to superior system in format of serial asynchronous string of ASCII with baud rate 9600Bd. Thesis describes service code for microcontroller in Assembler language and hardware construction of device.

Analog-Digital Converter Unit with Data Output by Serial Line
Lecián, Petr ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
This work is about measuring voltage and manipulating with this way obtained data. Manipulating system is in this case 16-bit microcontroler PIC by Microchip, that transforms input data to output using known non-linear trace. Microcontroler has been programed in the symbolic adress language. I had to create a unit that would be a part of the special device for indirect measuring non-electric quantity. Output data should be sent to the superior system by serial bus RS-232 for a next use.
