Abstract: A method of assembling an adjustable fluid-filled lens assembly comprising biaxially tensioning an elastomeric membrane to a surface tension of greater than 180 N/m, typically greater than 1000 N/m; thermally conditioning the tensioned membrane, e.g., for one hour at a temperature of about 80° C., to accelerate relaxation of the membrane; mounting the membrane to a peripheral support structure whilst maintaining the tension in the membrane; assembling the mounted membrane with one or more other components to form an enclosure with the membrane forming one wall of the enclosure; and thereafter filling the enclosure with a fluid. The membrane may be formed from an aromatic polyurethane, and the fluid may be a phenylated siloxane. In some embodiments, the membrane is able to hold a substantially constant surface tension of at least 180 N/m for a period of at least 12 months.

Abstract: A system and method for mitigating inventory risk and an enterprise resource planning (ERP) system incorporating such system or method. In one embodiment, the system includes: (1) a uniqueness factor calculator configured to assign, to parts in an associated production database, uniqueness factors that are a function of a number of different products into which said parts go and (2) a risk report generator associated with said uniqueness factor calculator and configured to generate a report of risks associated with said products and based on said uniqueness factors.

Abstract: An electrical light device suitable for an illuminated sign or for a lighting fixture comprising a relatively thin plate made of a unitary sheet of transparent or translucent material and having a peripheral edge and flat front and rear surfaces. A plurality of spaced-apart, light emitting diodes (LEDs) are mounted along the peripheral edge and are arranged to transmit light into the plate. A light reflecting, opaque layer covers the rear surface of the plate and a light reflecting, opaque strip is affixed to the peripheral edge and extends along this edge. The opaque strip is arranged to reflect light that has passed through the plate back into the plate. A front sheet or layer, that is at least partially opaque or translucent, extends over the front surface of the plate and provides a lighting effect. Preferably the front sheet is a plastic film attached by repositionable or pressure sensitive adhesive.
