Despite the considerable body of literature describing the demands of tennis, little is known about the accumulated physiological and mechanical loads associated with collegiate tennis tournament play. While microsensors have been used extensively to quantify demands in a variety of sports, particularly accelerometry and GPS sensors, limited data exists describing the demands of tennis match play using such microsensors (1,2). Aim. The purpose of this study was to use heart rate sensors and triaxial accelerometers to investigate the physiological and mechanical loads associated singles and doubles' tennis play during a single elimination collegiate tennis tournament.

Det finns ett behov av att utveckla en sensorlösning som kan bidra JU Solar Team med kördata från körning. Detta för att skapa underlag för mer verklighetstrogna statiska och dynamiska simuleringar av bilen. Arbetet har utförts vid Jönköpings Tekniska Högskola. I studien ingår utförda experiment samt programmering av ett flertal diverse sensorer och kretskort, både individuellt och sammansatt kopplade. Resultatet från arbetet visar att det är möjligt att skapa ett batteridrivet system som kan mäta samt lagra data från accelerometer, gyroskop, luftkvalitetssensor och lastceller oavbrutet under 24 timmar. Systemets kombination av lågt vikt och kompakt storlek gör att det inte stör föraren under tävling och skapar möjlighet att i framtiden bygga in systemet som en permanent del av solbilen. Studien avgränsar sig till att utvärdera möjligheten för att skapa ett konceptsystem som är tänkt att lägga grunden för vidareutveckling av framtida studenter.

This document describes a device capable to determine geographical position thanks to its GNSS module and measure the change of movement with the help of an accelerometer and gyroscope. Outputs of these integrated circuits are combined, data are processed and fused thanks to a numerical integration and mathematical filters. Results are stored on a memory card. The whole development is described from a concept, through the making of the device and software algorithms to the testing of its functions.

This master thesis is focused on the diagnostics of vibrations and noise of an internal combustion engine. The work also includes a summary of the current state of knowledge in which the quantities used, transmission paths, measuring devices and the possibilities of performing frequency analysis are analysed. As part of the technical experiment on which this work is based, vibrations and noise on the tractor engine are measured. The obtained data are then further processed using the BK Connect program. Subsequently, a frequency analysis is performed, specifically an order analysis. The conclusion of the analysis consists of an evaluation of individual orders that cause excitation that occur in the investigated motor.

The main aim of this thesis is to design and build automatic calibration system for inertial measurement sensors. The calibration system is intended to support the development of devices with inertial measurement sensors. The great emphasis is placed on the configurability of system and for this reason all calculations are realized by Matlab system, which is well known by engineers. There is also presented design of inertial measurement unit, which is used as a~model sensor unit for calibration system development.

Within this Master’s thesis, design and construction of a strapdown inertial navigation system based on MEMS sensors is described. The thesis includes theoretic analysis of physics behind determining the position of an object based on the object’s aceleration and changes in the object’s orientation in space. Included is also an overview of mathematical methods related to the position calculation.

The main subject of this thesis is use of inertial sensors for better motion and stability control of mobile robots. In background research are described the basic methods of mobile robots localization. Second part of background research is about mobile robot stability, in this part are described the methods of mobile robots stability control.

The term real-time operating system for embedded aplications has great importance today. This thesis descbires robitc arm control by mC/OS-II system on MC9S08JM60 platform. Robotic arm uses three servomotors HS-311 for motion, which are controlled by PWM. PWM pulse width is set according to the loaded data from the accelerometer, which is placed on DEMOJM board.

Diplomová práce je zaměřená na rozšířenou realitu a její realizaci pro mobilní platformu Android. V teoretické části je kladen důraz na obeznámení se s principy rozšířené reality, možnostmi její realizace pro mobilní platformu Android, která je také podrobněji představena. V praktické části se dále zaměřuje na návrh a realizaci knihovny a aplikace využívající tuhle knihovnu pro tvorbu rozšířené reality na platformě Android pomocí GPS a polohových senzorů. Aplikace slouží jako navigace a zobrazuje cestu ke konkrétnímu cíly, jak v podobě rozšířené reality, tak i na klasické dvourozměrné mapě. Práce podrobně popisuje navrhované řešení knihovny a aplikace a jejich implementaci. Nakonec popisuje testování, zhodnocuje dosažené výsledky a diskutuje nedostatky výsledného řešení a možnosti jeho vylepšení, respektive rozšíření.
