A position detecting apparatus for a medical device includes a transmission unit configured to transmit a magnetic field in each of a plurality of frame periods. The treatment of the fiber residue in the presence of alkali and mechanical shear produces a slurry containing amorphous insoluble cellulosic fiber. Said electrically conductive material may be configured to substantially form continuous electrically conductive paths and an electrically non-conductive material may be configured to substantially insulate said electrically conductive material. A handover interface is provided between the first access gateway and the second access gateway for enabling the MS to switch between the first and second radio access networks with minimum latency.
