A recycling bin divider that uses shape to indicate to the user that several types of recycling material that were previously required to be separated are now collected in one stream of refuse. The planar piece has an upper surface that is continuous and generally unobstructed. The implant includes at least one surface portion comprising a ground surface making up the first part and one or several delimited regions making up said second part. The locking portion includes a regulating portion positioned to face an edge portion of the mounting hole of the panel when the first connector and the second connector properly fitted together are mounted in the mounting hole so as to prevent the engagement between the locking portion and the locked portion from being released. In order to avoid potential hijacking attacks from entities other than the WCD, the home agent may, in conjunction with an authentication server, attempt to validate that that first NAI and second NAI are both associated with the WCD.
