Abstract: A packaging system comprising one or more multi-layer packaging pads applied to a pre-wrapped object, such as a metal coil, at high wear locations for increased abrasion resistance. The multi-layer packaging pad includes first and second plies and optionally a slip sheet. The first and second plies are disposed in an overlapping arrangement and have first and second inside slip surfaces, respectively, that face one another. The first and second plies are connected along only a sealed perimeter of the multi-layer packaging pad to provide a slip region between the first and second plies. The first and a second inside slip surfaces are formulated to slide relative to one another such that an unconstrained middle portion of the second ply is moveable relative to the first ply. Associated methods of manufacture and use are also provided.

Abstract: A stretchable multi-layer wrap is provided. The wrap comprises a first film, which comprises an inside cling surface, a second film, which comprises an inside cling surface. The second film inside cling surface engages the first film inside cling surface. The wrap also comprises a plurality of longitudinal ribs that are co-aligned with a longitudinal axis of the wrap. The ribs are disposed between the engaged cling surfaces and spaced so as not to cause disengagement of the cling surfaces.

Abstract: In the data packet router disclosed herein, a matrix of crosspoint switch elements connects data sources to selected destinations during each of a succession of intervals. Allocation of switch elements to desired connections is accomplished by a process which provides a data array having a number of data elements corresponding to the number of switch elements. During each interval, a source is assigned to each of the data elements in accordance with a first current pseudo-random shuffle pattern and a respective destination is assigned to each of the data elements in accordance with a second current pseudo-random shuffle pattern. A new set of shuffle patterns is generated during each interval. An incremental testing is performed across the data array to locate matches not previously allocated and each match found is successively allocated to this switch element corresponding to the data element.
