An elastic member of a semiconductive polymer comprising a conductive composition containing a conductive polymer and binder polymer, wherein the elastic member satisfies both characteristics of a variation of 1. This timing feature is useful in methods for increasing the throughput in the downstream direction by eliminating TCP ACKs backing up at a cable modem. The functions also enable changes, additions, and deletions of sources and destinations of transmissions to be made without modification of a source or destination application process and without taking a source or destination application process off-line. The aim of the invention is to provide a simple means of discharging a cigarette pack whilst ensuring that the packs are suitably presented to the customer.
