A spine stabilization system includes a flexible member attachable to a portion of the spinal column. Various data streams are combined such as by multiplexing by a multiplexing module. When in an intercom mode, an incoming call is handled in a manner that does not automatically terminate the intercom mode in response to the incoming call. The etching process is performed directly after the ion implantation performed in order to form deep regions of sourcedrain regions of the NFETs.
