My diploma thesis describes upgrade of flowbench serving as test rig for regulation valves characteristic measurement. At the beggining, there is an introduction to the water regulation valves theory followed by current machine condition description. Next chapter defines needed improvements and at the end follows proposition of improvements and necessary component definition and final realization. Final chapter summarizes complete project.

This thesis describes development of control algorithm for a wheelchair. Wheelchair should be capable of tracking and following a wall or a similar flat surface. Thesis is supposed to be an extension of the previous concept, whose purpose was to allow remote telepresence control of this wheelchair. SRF08 ultrasonic range finders are used to measure distance from the wall. Furthermore, image processing for mark detection is discussed. Purpose of these marks is to increase precision during final phase of the parking.

Distance and the associated parameters can be measured by specific sensors mobile device. Introduction The work focuses on the description of the sensors and the effects on their accuracy. To measure the distance, there is a number of good practices, which were described and demonstrated the application implemented source code for the Android platform. The project works with a total of three sensors, namely accelerometer, magnetometer and camera. The main objective of this work is the definition and application of methods for measuring distance using the appropriate sensors.

In this work I aimed at designing a universal system for testing either STM32F407/417 by STMicroelectronics and later various sensors and communication buses. The result then is a main board with many specific connectors for individual buses even with connectors making all I/O pins accessible at the same time. Thanks to advanced switching regulators the power supply is capable of accepting a wide range of sources like single Li-Ion cell, pair of alkaline cells, 12V Lead battery, common wall power adapters (both DC and AC up to 15 Vpp ), USB, laboratory power supplies with multiple outputs and finally POE (Power Over Ethernet). Supply voltages are supervised by voltage comparators with an optical signalisation. (It is possible to determine the sick branch without a measuring instrument and blowing components in the most cases.) Another important parameter was a robustness of the supply and communication lines. There is a number of TVSs, chokes, and big and low ESR capacitors A PC software is intended for a basic functionality demonstration only.

In this diploma thesis, the reader is familiarized with polymer optical fiber (POF). Firstly is mentioned theoretical background of optical fibers and optical transmission. The following are the basic properties and significant parameters of POF, a more detailed description of each type POF and their essential advantages and disadvantages in comparison with established optical fibers based on glass. The next chapter describes the area of practical issues: working with fibers and fiber installation, as well as the available connectors and methods of measurement of POF. Closely are analyzed knowledge of the practice, including the utilize in the aerospace and automotive industries, as well as in industrial networks, access data networks and local area networks. The practical part includes the measurement of basic transmission and mechanical parameters, including analysis of the results. The conclusion summarizes all the findings and results of this work, including possible future developments.

This thesis describes optimization and modification of standard thick-film electrochemical sensor to be able to be used for detection in microvolumes. In the theoretical part, the thick film technology is described. The work is then focused on the wettability of surfaces followed by introduction to electrochemistry and electro-analytical methods. In the experimental part, screen-printing of various types of thick film pastes on ceramic substrates for determination of their wettability and the following modification of the sensors with thick-film paste and with Parylene vaporization can be found, as well as the basic electrochemical measurements in microvolume using the modified sensor. Finally the results are summarized in conclusion.

This document deals with issues of testing semiconductor inertial sensors like gyroscopes and accelerometers, but also other sensors like magnetometers, inclinometers and others for aviation navigation purposes where strict requirements cover every system. The goal of this thesis is to create modular test platform for testing wide variety of sensors in different combinations under variable circumstances. The development covers mechanical design, electrical design – hardware and also control algorithm – software.

This thesis compares the methods for the determination of air and moisture condensation in the construction. There are descriptions of the various methods and formulas for measuring humidity and methods for the calculation of condensation in building structures. The practical part describes the development of a method for verifying the condensation of moisture in construction. Parts of this work are the materials and methods for the development of the humidity sensor. There were used two methods – capacitive and resistive for measuring moisture condensation. In the conclusion is the evaluation of the humidity sensor and compares the results of individual measurements.
