A method and apparatus for radio resource control messaging. A first group of the coil conductor patterns defines a first coil portion of a high-permeability coil unit. The arm is formed with a plurality of joints at or between its ends, each joint having one or more rotational degrees of freedom while providing resistance to rotational movement in the one or more degrees of freedom, such that the free end of the arm can be moved in three dimensional space, and such that the arm is self-supporting. A method of making a web includes providing a web and discrete quantities of a polymeric material. The safety system encompasses means for testing the sensors and the conductors to the sensors. Then, whether the input sound signal matches one of known sound standards is determined based on the determined results above.
