Abstract: In one implementation, a method of achieving an objective using a scene graph includes identifying a set of transition couples of a plurality of transition couples between sets of spatial relationships of the scene graph, wherein each spatial relationship of a respective first set of spatial relationships indicated by each transition couple of the set of transition couples is included in an initial set of spatial relationships or an respective second set of spatial relationships indicated by a previous transition couple and wherein a particular spatial relationship is included in a respective second set of spatial relationships of a last transition couple of the set of transition couples.

Abstract: A package configured to hold product includes an active component and a label. The active component can be placed on or attached to an interior surface of the package and the label can be placed on or attached to an exterior surface of the package. The label can be placed on the package to cover the active component so that the active component generally cannot be seen from the external environment.

Abstract: A method is described herein for slowing, inhibiting, and/or preventing the growth of microbes, or for killing microbes, within and/or on a product/good that is stored in a package. The method can include applying a film cover over a perforated portion of a package and securing the film cover to the package at the perimeter of the perforated portion with an adhesive or by heat stacking. The film cover can include a material for changing the atmosphere within the package. The package may be an existing pre-perforated package, or may be a package that requires perforation. If the package requires perforation, the method can further include perforating at least a portion of the package prior to positioning the film cover over the perforated portion. The film cover can be formed of a three-phase material or other material.
