An indicator has a permanent magnet and a coil rotatably supported on the permanent magnet and wound so as to form a surface that is parallel to and disposed at a preselected distance from a bottom surface of the permanent magnet. The resulting compositions and their various uses thereof are also described. The uplink information reflects performance of specific equipment that is in use by the wireless customer. A heating process is performed to form a sourcedrain area in the substrate under the doped metal silicide layer.
