Abstract: A multi-interface point-to-point switching system includes a plurality of I/O devices coupled to a plurality of respective devices, a switching device for selectively delivering each of a plurality of different signals from a selected one of the I/O devices coupled to a sending one of the devices to another selected one of the I/O devices coupled to a receiving one of the devices, to thereby establish respective connections between the sending and receiving devices, wherein the switching device provides a fixed, low latency signal path for each connection between a sending and receiving device for the duration of that connection, whereby the latency of that connection is deterministic and predictable, and a data content of the signal delivered via that connection is not analyzed by the switching device, whereby the switching device operates in a content independent manner, and controller device that determines the fixed, low latency signal path for each connection and commands the switching device to establis

Abstract: Compared to a polyester film, films made from a blend of the polyester and up to 20 percent of an ethylene-acrylate copolymer have improved tear strength and heat seal strength while maintaining acceptable gloss, clarity, and coefficient of friction. The heat seal strength of the film and the bond strength of the film to aluminum vacuum deposited on the film are improved by adding less than five percent of an ethylene-acid copolymer to the blend.

Abstract: A coextruded film suitable for packaging a flowable material, particularly milk, in a form, fill and seal machine comprises a core layer of a blend of high density polyethylene and linear low density polyethylene and skin layers of a blend of linear low density polyethylene and ethylene-methyl acrylate copolymer.

Abstract: When a film consisting of high density polyethylene and about three percent polystyrene is run on an interfolding machine to produce interfolded sheets of the film for use as deli wrap, the film is completely and consistently cut in the machine into sheets that are entirely separated from adjacent sheets. In comparison, sheets made from film consisting of 100 percent high density polyethylene are not consistently completely separated from adjacent sheets.
