A system for discovering, identifying and managing ad hoc networks and facilitating the communications within that network is disclosed. The method according to one embodiment includes transmitting, at the base station, information of one or more CSI-RS configurations to the mobile station; and transmitting, at the base station, at least one downlink subframe mapped with the CSI-RSs to the mobile station. The robot includes a cleaning assembly mounted on the forward portion of the chassis and a bin disposed adjacent the cleaning assembly and configured to receive debris agitated by the cleaning assembly. Under a fireproof mode, the moveable frame and the object slide to the second position, and are received in the fireproof chamber. Each longitudinally extending section is configured to overlie at least two stringers of a respective fuselage section. An ice storage bin includes an ice storage bin body having an insulated front, a back, a bottom, opposite sides, and an open top, and a first window pane and a second window pane positioned at the front of the ice storage bin to allow for viewing the ice level within the ice storage bin.
