patient is placed in a strong magnetic field which causes the protons in the water molecule of the body to align in either a parallel (low energy) or anti-parallel (high energy) orientation with the magnetic field. Then a radiofrequency pulse is introduced which forces the spinning protons to move out of equilibrium state. When a radio frequency pulse is stopped, the protons return to equilibrium state and produce a sinusoidal signal at a frequency dependent on the local magnetic field. Finally, a radio
CHAPTER 1 INTRODUCTION 1. INTRODUCTION 1.1Bipedal Robot:- The term bi-pedal robot refers to a robot that walks on two legs. In the recent years there has been much interest stimulated in dynamic walking in bipedal robotics and legged locomotion in general. Part of reason for this interest is the need for robot which can operate in human oriented environments. Human presents a very elegant model of locomotion to emulate. The Bipedal robots will operate in the human environment with much
non-healing chronic injury (Guo S., et al., 2010). The presence of a chronic injury can hinder day to day life and also the affected persons. In case of older peoples, presence of wound can be debilitating them and altogether meddle with their self consideration.
