1. Micromachined Three-Axis Accelerometers and Sensor Readout Electronics
Sammanfattning : Miniaturized, MEMS-based, inertial navigation systems are used to track the position of moving objects without an external reference system. Several existing and future applications such as indoor navigation, stability control of vehicles, active prostheses or training aids for sportsmen would benefit from the small size and the low cost of micromachined inertial sensors.

2. Gravity Illustrated. Spacetime Edition
Sammanfattning : This thesis deals with essentially four different topics within general relativity: pedagogical techniques for illustrating curved spacetime, inertial forces, gyroscope precession and optical geometry. Concerning the pedagogical techniques, I investigate two distinctly different methods, the dual and the absolute method. LÄS MER
3. Signal processing for MEMS sensor based motion analysis system
Sammanfattning : Sensor systems for motion analysis represent an important class of embeddedsensor systems for health, and are usually based on MEMS technology(Micro-electro-mechanical systems). Gyroscopes and accelerometers are two examples of MEMS motion sensors that are characterized by their small size,low weight, low power consumption, and low cost. LÄS MER
4. Inertial Measurement Unit based Virtual Antenna Arrays - DoA Estimation and Positioning in Wireless Networks
Sammanfattning : Today we have different location based services available in a mobile phone or mobile station (MS). These services include: direction finding to nearby ATMs, locating favorite food restaurants, or finding any target destination. LÄS MER
5. Joint Positioning and Multipath Radio Channel Estimation and Prediction
Sammanfattning : This thesis investigates the topic of joint positioning and radio channel estimation and prediction. Both positioning and radio channel estimation have a long history of research with many publications but the combination of the two has so far at large been left unexplored. LÄS MER
