Abstract: A polymeric film, sheet, or extrusion coating is formed as a multilayered structure having at least one A layer and at least one B layer. The polymeric film, sheet, or extrusion coating is able to include at least 30% recycled content resin while also exhibiting improved stiffness and strength relative to films with purely virgin polymers. One embodiment of the present invention further presents improved oxygen barrier properties relative to existing films, sheets, or extrusion coatings. Due to the strong structural properties, the polymeric film, sheet, or extrusion coating allows for the inclusion of recycled content into applications where recycled content has previously not been able to be included, such as flexible food, pharmaceutical, or cosmetics packaging.

Abstract: A measurement strut for measuring a separation between two relatively moveable support members of a machine (for example, a robot arm). The strut is removably couplable between the two support members and is adapted to become at least partially decoupled from at least one of the support members when a compressive force developed in the strut by relative movement of the support members is greater than a predetermined threshold. By becoming at least partially decoupled from at least one of the support members, at least some of any excess relative movement of the support members towards each other can be absorbed, thereby helping to prevent damage being caused to the strut by attempting to compress the strut beyond its minimum range of travel.
