Accelerometer-based monitoring of steering wheel angle
Navrátil, Tadeáš ; Jirgl, Miroslav (referee) ; Mihálik, Ondrej (advisor)
This thesis deals with the design of a device which will be used for measuring the steering wheel angle. Main goal was to design basic concept of device which is using data gathered from three accelerometers in the reconstruction algorithm to get steering wheel angle. Discussion of various reconstruction algorithms (with regards to simulated output noise levels from acceleromater) and final Implementation of reconstruction algorithm (in MATLAB simulink enviroment) is also part of this thesis. Furthermore, thesis deals with the selection of suitable components. Mainly selection of accelerometers, microcontroller and the selection of a suitable communication bus for mutual communication between them. Thesis also deals with design improvements of algorithm and realization of the whole device. In the end, we compare results of measuring device and inner senzor of steering wheel.

MEMS Technology for Tilt Sensing
Kopeček, Pavel ; Čížek, Martin (referee) ; Dlouhý, Jiří (advisor)
Recently we put more requirements on the equipment around us. And very often we need know, how hung angle-wise of equipment is. Measuring of tilt is very important and used for example in gaming consoles, mobile phone, medical purposes and other. Tilt is calculated per direction of gravity acceleration, it measures by accelerometers. Accelerometer is sensor, which exploit masses inertia to calculate of acceleration. Development put pressure to us and reason is miniaturizing of everything and there is possibility to use micro-electromechanical, so-called MEMS, accelerometers. At last time sensors made by MEMS technology replacing classical mechanic sensors, which is bigger, more power exacting and last time considerably more expensive. But parts makes by MEMS technology aren’t enough accurate for some applications. Despite it is by this principle manufactured much kinds of accelerometers with different technologies of manufacture and work on different principles. We try to compare two accelerometers from two competitive factories.

Use 8x8 LED Matrix and MEMS Sensor for Promotional Purposes
Středa, Jakub ; Matyáš, Pavel (referee) ; Zuth, Daniel (advisor)
The main objective of this bachelor thesis is to create exemplary application for promotional purposes. It means using of a microcontroller ATmega32A, a MEMS acceleration and angular velocity sensor and a LED matrix with a driver.. In the theoretical part the thesis is focused on the characteristics of used components, their features and way of control. Subsequently, the thesis deals with a power supply, design and manufacture of a printed circuit board for microcontroller and the last part of the thesis is focused on a microcontroller's software and manufacture of a casing.
