In this paper we present a micro-electrical mechanical system (MEMS) based pedestrian navigation system (PNS) for seamless positioning. The sub-algorithms for the PNS are developed and the positioning performance is enhanced using the modified receding horizon Kalman finite impulse response filter (MRHKF). The PNS consists of a biaxial accelerometer and a biaxial magnetic compass mounted on a s...

The 21st century sees significant breakthroughs in fabricating micro devices in the quest of miniaturising. Most micro parts have been manufactured in the range of less than 1mm. However, they are built based on material that is process dependant, resulting in monolithic parts. For example the Integrated Circuits, Micro Electro Mechanical System (MEMS) are silicon based, and on their own do not...

Both “actions” and “interactions” are micro-operations that can be aggregated from a system’s perspective. Whereas “actions” operate historically, “interactions” provide the events with “meaning” from a hindsight perspective. Luhmann’s sociology of communication systems adds to the approach of symbolic interactionism the question what global dimensions of communication mean for local interactio...

Today many position aware devices are demanded. Micro-Electro-Mechanical Systems (MEMS) can detect their own acceleration. Out of these values the movement, and thus the new position, can be calculated. The problem of these systems is, they are very error-prone. In order to minimize the fault this paper introduces a new way of combining different MEMS measurements to achieve a more accurate rel...

Both ‘actions’ and ‘interactions’ can be considered as micro-operations that can be aggregated from a systemic perspective. Whereas actions operate historically, interactions provide the events retrospectively with meaning.
