A coaster for a beverage container has an enclosed base and a cooling material encapsulated therein. With this axial flow fan motor, when two axial flow fan motors are stacked in the axial direction and either one is selectively used, the blades of the other fan motor that is stopped do not obstruct airflow from the fan motor that is being driven. The distal portion further includes an articulation layer disposed over the tubular wall and includes a first series of slots, which allow controlled bending of the distal portion by movement of one or more of the pull wires. A next primary signal component record is then obtained from the residual record. The display representation may include the drawing elements associated with the one or more layers, and the appearance of the drawing elements associated with the first layer is based on the viewport display property.
