Heat pump
Klíma, Martin ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
Bachelor thesis describes and characterizes the heat pump. Summarizes the various types of heat pumps in terms of energy production, principles of their function and description of the differences between different types of compressors, use of refrigerant and its future development. Finally, here is my own view given the heat pump, which I prefer.

FM Transmitter of APRS Telemetry in 435 MHz Band
Klíma, Martin ; Špaček, Jiří (referee) ; Urbanec, Tomáš (advisor)
FM transmitter APRS of telemetric data is device able to measure telemetric values from its ambient. It is able to send this data to user on earth by radio frequency channel. This device can create data frames, with proper formatting allowing sending data. It operates in 435 MHz band, uses FSK and AFSK modulation. This work describes basic information of used protocols, electronic connection of this transmitter and software equipment.

Microprocessor Controlled Power Measurement System for Frequencies below 10GHz
Klíma, Martin ; Lukeš, Zbyněk (referee) ; Urbanec, Tomáš (advisor)
The aim of this work is to design a microprocessor controlled power measurement system which is based on the logarithmic detector AD8317, then to create a printed circuit board and to test its functioning. The logarithmic detector AD8317 is acceptable for measurement of high frequency signal’s power of the level between approx. –55 dBm and – 3 dBm in the frequency bandwidth of 1 MHz to 10 GHz. Its output provides DC voltage which is corresponding to the decibel-scaled level of the input signal. This is suitable for A/D conversion and digital processing by the microprocessor. The result of the work is a complete measurement system.

Universal timer for sport activity
Janůš, Tomáš ; Klíma, Martin (referee) ; Macháň, Ladislav (advisor)
This bachelor thesis deals with a proposal and implementation of wireless electronic time measurement. In the thesis a proposal and implementation of simple wireless time measurement is described. Its part is also a proposal and creating of the optical barrier. The theoretical part further contains description and usage of various sensors. All sensors are wirelessly interconnected with the main device. The time measurement is being processed in the computer by means of a created programme which enables to control the time measurement and to save measured times as well.

The lamination of Low Temperature Co-fired Ceramic
Hudeček, Ondřej ; Klíma, Martin (referee) ; Kosina, Petr (advisor)
Master’s thesis deals with the optimalization of low-temperature cofired ceramic lamination process that affects the final quality of 3D structures (eg., channels, cavities, membranes, etc.). The paper evaluates the influence of lamination parameters (pressure, temperature, time) on the formation of defects in the structure, which were detected by appropriate methods. The last parts describes designed and simulation cooling water system using LTCC technology.

Personal communicator for strategic sports
Válik, Martin ; Klíma, Martin (referee) ; Macháň, Ladislav (advisor)
The aim was to design connept of personal communicator useable for strategic sports such as airsoft or painball. Personal communicator provide wireless transmission of position provided by GPS module, eventually other data via RF module. Interactive user interface is solved by TFT touch display. For controlling of modules is used 32-bit ARM based microcontroller. The output is demonstration of functionality of communication and vizualization of distance between two designed devices on TFT display.
