Abstract: A method of identifying association of a backhaul unit to a node device connected to the backhaul unit in a network is disclosed. The network comprises a plurality of backhaul units each arranged for connecting to a node device and for providing network connection to the node device. The method comprises the steps of: obtaining a data consumption pattern related to a node device over a time period; obtaining data consumption patterns of the plurality of backhaul units over the same time period; matching the data consumption pattern of the node device to one of the data consumption patterns of the plurality of backhaul units; and identifying association of the node device to a backhaul unit having the matched data consumption pattern.

Abstract: A sanding tool includes a body and a battery pack. The body includes a housing formed with a battery pack coupling portion, a main handle connected to the housing, a sanding assembly connected to the housing with a base plate, where the base plate forms a support plane; and an electric motor in the housing. The mounting surface of the battery pack is at least partially disposed between the electric motor and the main handle. The projection point of the center of gravity of the whole machine on an extended surface of the support plane is located within the support plane of the base plate. Along the front and rear direction of the housing, the base plate has a first centerline, and the distance from the projection point to the first centerline is greater than or equal to 0 mm and less than or equal to 38 mm.

Abstract: The invention provides a method and apparatus for managing end nodes of a Low-Power Wide Area Network. A mode change command indicating a desire to switch the operating mode of each of a plurality of end nodes is broadcast. A determination is made as to whether all the end nodes have switched mode to match the desired operating mode, and the mode change command is rebroadcast if it is determined that not all end nodes have appropriately switched mode.
