Thus, while being filled, the bags are initially stabilized from the corners, as a result of which a certain tension remains in the walls between the corners, so that the walls cannot bulge out when the level of the filling material rises. In one example, the setting component is connected to communicate a rapid cooling setting input by the user to the control system. As a result, light that is provided by the fore optic is reconfigured by the micro lenses having various focal lengths to be substantially focused along the plane of the array of opto-electronic devices.
