Item Open Access Personal navigation via high-resolution gait-corrected inertial measurement units(IEEE, 2010) Bebek O.; Suster, M.A.; Rajgopal, S.; Fu, M.J.; Huang X.; Çavuşoğlu, M. Cenk; Young, D.J.; Mehregany, M.; Van Den Bogert, A.J.; Mastrangelo, C.H.In this paper, a personal micronavigation system that uses high-resolution gait-corrected inertial measurement units is presented. The goal of this paper is to develop a navigation system that uses secondary inertial variables, such as velocity, to enable long-term precise navigation in the absence of Global Positioning System (GPS) and beacon signals. In this scheme, measured zero-velocity duration from the ground reaction sensors is used to reset the accumulated integration errors from accelerometers and gyroscopes in position calculation. With the described system, an average position error of 4 m is achieved at the end of half-hour walks. © 2010 IEEE.Item Open Access Pressure measurements, methods(Springer, 2015) Çetin, Barbaros; Taze, Serdar; Li, D.; Li, D.Experimentation and novel measurement techniques are crucial for the further development of microfluidic devices. Pressure is one basic parameter involved in microfluidic experiments. However, it is not realistic to apply the conventional pressure measurement techniques to microsystems, since the characteristic dimension of these measurement instruments is already comparable with the size of the microdevices. Therefore, novel pressure measurement methods are needed for pressure measurement at the microscale.
