Disclosed is a method and system for interrupting a transmitting subscriber where the transmitting subscriber communicates on a forward channel of a wireless communications system while listening to a reverse channel for reverse channel signaling. The system includes a search engine that searches a set of calendars under the control of a Finite State Machine, a current pointer and input signals from array and a clock line providing current time. The flexible wire is wound around an outside gap of the helical spring so as to make the flexible wire helical and wrap the whole helical spring. A second spacer layer having a thickness equal to the determined difference between the initial width of the initial spacers and the target width is formed upon the initial spacers and the structure.
