A method, computer readable storage, and apparatus for implementing a recursive hierarchical segmentation algorithm on a parallel computing platform. The method includes generating a velocity estimate that includes a speed and a direction of a wireless receiver. The top plate may include an opening for receiving the rod. Finally, one or more projections extend downward from the bottom of the hull. Further provided are systems, devices, methods, and compositions for obtaining magnetic resonance information of a region within a biological subject without the need or use of an external-magnet. The control section identifies feature points for each component that exist in a series of acceleration data, generates feature point data for each component which includes the plurality of feature points as inputted character data, and collates it with basic character data.
