Design of corrugation measuring device
Valena, Martin ; Omasta, Milan (referee) ; Galas, Radovan (advisor)
This bachelor thesis describes the development of experimental corrugation measuring device. In the first part, mechanisms of corrugation formation and classification of corrugation, together with an analysis of measuring devices are described. According to the analysis, several design configurations were developed. The final variant is described in detail, together with the calculations. The output of this bachelor thesis includes complete technical drawings and price estimation.

Textile electrodes in ECG measurement
Kocum, Filip ; Vélim, Jan (referee) ; Cupal, Miroslav (advisor)
This semestral thesis deals with the issue of electrocardiogram measurement and heart rate detection using textile electrodes placed on the body. One of the main tasks was to design the possibilities of attaching the sensors to the body in order to ensure the best possible adhesion to the skin. The work focuses on the design of suitable electrode placement in terms of functionality and stability of measurement. Furthermore, the work focuses on the comparison of textile and Ag / AgCl electrodes. The last point was the design of a preamplifier for measurement and its subsequent implementation.

Measuring device connected over USB
Flek, Tomáš ; Strašil, Ivo (referee) ; Krajsa, Ondřej (advisor)
In essence, this master’s thesis focuses on search and project on optimal electrical scheme, which will substitute for digital oscilloscope function. The thesis consist of three parts, first part is about problems associated with oscilloscope signal sampling and data bus descriptions, second part where are selected particular circuits, electrical scheme, eventually shown different options which could be used. Third part consists of software function description developed for controlling microprocessor. In choosing of analog devices, are focused on parameters like maximal input voltage on which the device has most ideal parameters, but also parameters, which are critical for particular block, like for example input impedance, device noise, operating amplifier input voltage and current offset. All devices were chosen with battery supply possibility, so what the lowest possible power consumption. In this thesis is theoretically described each circuit block and reasons for their selection.

Thermodiagnostics – contact and contact-free temperature measurements
Mikula, Martin ; Jankových, Róbert (referee) ; Hammer, Miloš (advisor)
This thesis is concerned with thermodiagnostics in industrial practise, which is very important for the assessment of technical condition of object on the basis of temperature, in today's time. It includes summary of contact and contact-free methods and their principle, advantages and disadvantages for aplication in industrial practise. Because of thesis it was carried out measurement in company Daikin Device Czech republic with the use of contact thermometer and two available thermocameras for solving of topical tasks relating to production.

The dam Letovice - the design of the reconstruction of the technical surveillance system
Vahalík, Zbyněk ; Špano, Miroslav (referee) ; Říha, Jaromír (advisor)
This bachelor thesis deals with the design of the reconstruction of the technical surveillance system of the dam Letovice. The introductory part describes the area of the dam, dam's surroundings and the dam itself with the particular objects. The subsequent section describes the technical surveillance system and a list of existing measuring devices with description. This is completed by the measurement results of the technical surveillance system from previous years. Additionally, it also contains the list of devices, which will be removed during the reconstruction. The final part deals with the design of the new technical surveillance system, list of measuring devices and their characteristics.
