Abstract: Systems, devices, and techniques for handover and false base station detection in a wireless communication network are described. A described technique performed by a user equipment (UE) includes receiving, from a source base station of a wireless network, a handover command to indicate a handover to a target base station for communication in the wireless network; receiving information from the target base station; determining whether the target base station is a legitimate base station of the wireless network based on the information from the target base station and handover information included in the handover command; and performing a handover based on the handover command and a determination that the target base station is the legitimate base station.

Abstract: A machine has: an outer member; an inner member mounted for rotation about an axis relative to the outer member; and a seal system. The seal system has: a seal housing mounted to the outer member; one or more seal rings held by the seal housing and having an inner diameter surface; and a seal runner mounted to the inner member and having a first outer diameter surface portion contacting or facing the inner diameter surface of the one or more seal rings. The seal runner has a circumferential array of mounting features. One or more weights are mounted to one or more of the mounting features.
