A machine moves shoe strobels to a camera or scanner where images of the strobels are captured. In one aspect, the lighting apparatus includes a light source, a plate, and frame. The siphons of the invention are designed such that the inlet of the siphon on the first chamber is radially outward of the siphon outlet on the second chamber. The composite material and the at least first and second layers of flanking material are heated as they pass through the die to cure the composite material and bond the at least two flanking material layers to the composite material, thereby forming a cured article. The mobile device may further include a housing, with the battery, battery charger, and image sensor contained within the housing.
