Inclinometers and Gyroscopes
Hývnarová, Irena ; Beneš, Petr (referee) ; Havránek, Zdeněk (advisor)
This study deals with tilt sensors. Besides others methods, accelerometers and gyroscopes are also convenient to solve this problem. Tilt sensors which are described in this thesis are working with capacitive, piezoresistive and thermal method. Capacitive accelerometers from producer Analog Devices, STmicro and Freescale, piezoresistive accelerometers from producer Panasonic Matsushita and gyroscope ADXRS300 are tested by practical measurement. Parameters of these accelerometers are found and they are compared with parameters from producer. Measurement reliability in this study is analysed as well. This thesis is divided in chapters theoretically describing principles of particular accelerometers and the chapters containing measured data evaluation.

Measurement and analysis of dynamic properties of rotating machine parts
Gofroň, Vojtěch ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
Diploma thesis focuses on measurement and analysis of shaft motion, torque, angular velocity and vibration. First part of the thesis deals with general issue of acquiring a digital signal. Next part describes suitable sensors for each measurement type, and data acquisition hardware. The last theoretical part describes methods for measurement data analysis and vibration diagnostics. Practical part of the thesis describes shaft motion and torque measurements made on laboratory equipment, and vibration measurement made on real machine system. Each measurement includes measurement data analysis and evaluation.

Accelerometric Distributed System
Kopečný, Martin ; Číp, Ondřej (referee) ; Václavík, Vlastimil (advisor)
This thesis deals with principles of measuring of acceleration with commercially available accelerometers and theoretical analyses of measuring of angular speed of rotational motion. Then the proposition of application’s connection controlled by microprocessor and software solution with implementation of serial communication interface is described. The function of the apparatus is examined with experimental measuring and elaborated protocol.
