In assembly processes, there is a trend to equip hand-held tools with localization to improve quality assurance. An analysis of localization systems for specific use cases is presented with focus on accuracy, availability and effort. For tightening processes with hand-held tools it is demonstrated how context detection, e.g. motion, motor and tight...
Requirements for efficiency in manufacturing processes are steadily increasing in global competition. Through digi-talization and data analytics, not only efficiency but also flexibility and quality are to be increased. In spite of everything, even in highly automated production plants, such as in the automotive industry, numerous work steps are ca...
The invention relates to a system for determination the position of a mobile user device (10). The system comprises a state determination device (120), comprising a transmitting unit (122) and a state determination unit (124), and the mobile user device (110), comprising a receiving unit (112) and a processor unit (114). The mobile user device (110...
Wi-Fi RSS Fingerprint based navigation has enjoyed increasing popularity as a solution for indoor navigation in the last decade. Recently, methods for interpolation of Wi-Fi databases have become the focus of research. This paper shows how common models for Wi-Fi signal propagation can be included into the interpolation method by using universal Kr...
A tracking algorithm for position and azimuth estimation based on Wi-Fi fingerprinting with directional antennas is analyzed and evaluated. A particle filter is used for fusing received signal strength of Wi-Fi with sensor readings of an inertial measurement unit, which is combined with pedestrian dead reckoning. Two setups for different applicatio...
This paper demonstrates a novel approach for motion classification and analysis using pressure sensors worn by a person. The pressure signal is analysed to search for features corresponding to the motion states, and matched against typical human walking pattern. A prototype system is developed which provides motion classification results in real-ti...
