In underground mines and tunnels accurate and continuous positioning of moving machines and humans has been studied extensively. Geomagnetic field based positioning is an interesting possibility for this measurement need. Using a commercial smart phone and a new calculation service provided by a Finnish company, a feasibility and accuracy assertion tests were done in Finnish underground mine. F...

Consistent monitoring of vital health parameters is an important issue in the medical industry. With recent technologies we are able to carry out remote monitoring of physiological parameters in patients. This allows communication between a patient and medical personnel using a smart-phone, which will collect, analyze and transfer heart rate and oxygen saturation data for subsequent review by a...

With the outburst of smart-phones today, the market is exploding with various mobile applications.
