MEMS Inertial Sensor
Mihaľko, Juraj ; Rášo, Peter (oponent) ; Beneš, Petr (vedoucí práce)
The aim of this master’s thesis was to describe the basic measurement methods for measurement of inertial sensor, their physical principles and errors. The next step was to select a specific parameter, then test it on a number of sensors and evaluate the results. Measurement of inertial sensors is very important for the parametrization of their errors and their subsequent mathematical model by which it is possible to minimize their impact on inertial navigation. The practical part is dedicated to the measurement of stability of the offset. Data acquisition card NI-USB 6215, which can supply two accelerometers at the same time using analog outputs, was used for data acquisition and power supply. It was tested on seven inertial sensor from four manufacturers. Two connection methods with NI-USB 6215, by whose it was determined which one is better to suppress the crosstalk between channels, were used for measurement. The NI PXI 4462 was used to verify that the NI-USB 6215 card is sufficient. The parameters for description of the changes in inertial sensors were established, transition between the initial and final value of the output measurement, variance of the values on which the sensor fixates after 72 iterations, and the fixation time of the sensor.

Wireless sensors network for measurement of soil water potential
Rášo, Peter ; Klusáček, Stanislav (oponent) ; Havránek, Zdeněk (vedoucí práce)
The purpose of this project is to create a wireless sensor network for the measurement of soil water potential. This work includes the description of measurement methods, selection of appropriate method and its calibration. It also contains hardware and firmware realization of the two types of modules, the end station with sensors and the base station for data reception. The whole application contains a user program which allows data logging, displays actual data or past characteristics and changes the system settings with a possibility to demand system for the necessary information.

MEMS Inertial Sensor
Mihaľko, Juraj ; Rášo, Peter (oponent) ; Beneš, Petr (vedoucí práce)
The aim of this master’s thesis is to describe the basic measurement methods of micro-electromechanical inertial sensor, their physical principles and errors. Measurement of inertial sensors is very important for the parameterization of their errors and their subsequent mathematical model by which it is possible to minimize the measurement error impact on inertial navigation. The practical part is dedicated to create automated measurement setup for measurement stability of the offset. Hardware and software from National Instruments is used in measurement chain. The work is next focused on measuring seven inertial sensors based on three different physical principles. In addition to creating measurement setup, we also defined three inertial sensor parameters, describing theoretical behavior of the sensor output.

Bezkontaktní měření geometrických parametrů pružin
Bortlík, Pavel ; Rášo, Peter (oponent) ; Beneš, Petr (vedoucí práce)
Tato bakalářská práce obsahuje rozbor problematiky bezkontaktního měření rozměrů mechanických dílů. Na základě rozboru vlastností dostupných snímačů obsahuje předložení návrhu vhodného optického snímače pro bezkontaktní měření geometrických parametrů pružin. Součástí práce je návrh automatizovaného přípravku pro ověření vlastností snímačů a následné využití pro reálné měření pružin v laboratorních podmínkách. Pro testovací měřicí soustavu určenou k ověření vlastností snímačů a měření geometrických parametrů pružin včetně výpočtu a vyhodnocení odchylek je navržen a popsán obslužný software. Součástí práce je návrh obslužného softwaru, který umožňuje automatizaci bezkontaktního měření rozměrů mechanických dílů v praxi. Proces zpracování a vyhodnocení dat je popsán blokovým schématem s vyobrazenými průběhy v jednotlivých krocích.

Vision sensor
Rášo, Peter ; Havránek, Zdeněk (oponent) ; Bejček, Ludvík (vedoucí práce)
This bachelor thesis describes the vision sensors and their industrial applications. It is divided in to the 4 main parts: hardware problematic, software problematic, applications, comparison and the market survey of the vision sensors. The special part of this work is a description of working station for demonstration basic characteristics and application possibilities of vision sensor VeriSens 1200 which will be used in laboratory education. Solution of non-typical applications is described in lighting techniques. Program documentation of vision sensor VeriSens 1200 from Baumer helps with design and particular steps of this application.
