Abstract: An attachable closure device for reclosing contains a base member, a resilient expandable band coupled to and extending from the base member, an adhesive layer on a surface of the base member, and a release agent on the adhesive layer. The release agent is housed in a coating on a release support layer, which may be coupled to the base member and unitary with the base member. The resilient, expandable band may be coupled and retained to the attachable closure device solely by a portion of the unitary base member-release support layer.

Abstract: A bitmap comparison technique that is able quickly to compare two bitmap images while discounting differences between the images likely due to noise. The bitmap comparison technique includes the operations of: comparing the first and second bitmaps, producing a difference map identifying differing bits between the first and second bitmaps, producing outline masks based on the outlines of the first and second bitmaps, identifying certain very different bits within the difference map that are to be weighted differently from the remaining bits within the difference map based upon the outline mask, and determining a comparison score to indicate the extent to which the first and second images differ by differently weighting the very different bits and the remaining bits. The certain bits are normally weighted to a lesser extent than the remaining bits when determining the comparison score so that the influence of noise in the comparison score is diminished.
