Abstract:
1. A barrier system, comprising: a barrier having a first end and a second end; a spool coupled to the first end of the barrier, the barrier being positioned to be wound onto and off of the spool; an electrical component at the second end of the barrier; a drive assembly coupled to the second end of the barrier and configured to enable movement of the second end of the barrier toward and away from the spool as the barrier is wound onto and off of the spool; and a resilient line between the electrical component and the drive assembly at least partially housed by a support structure and configured to convey signals between the electrical component and the drive assembly, the resilient line being further configured to extend from the support structure when the barrier is wound off of the spool and to retract into the support structure when the barrier is wound onto the spool.
