Abstract:
An electrochromic display module employing a unique combination of architecture and electrochromic composition to provide an extended life to the module. The architecture may involve the use of an extended seal about a perimeter of a display portion where the composition is located. In this manner, the rate of solvent leakage from the composition may be substantially reduced. Additionally, the electrochromic composition itself may make use of particular low volatility solvents and constituent combinations so as to discourage the amount particle generation therein. Ultimately, an electrochromic display module having a useful life of more than about 3 years may be provided.

Abstract:
A press fitting arrangement includes a sealing ring to be housed within a bead of a press fitting into which a tube is to be inserted. There is at least one gap between the press fitting together with the sealing ring and the tube which is closed by pressing at least one portion of the press fitting. The sealing ring has at least one first portion along the majority of its circumference. Each first portion of the sealing ring has an outside diameter (SOD1) prior to fitment into the press fitting bead which is larger than the inside bead diameter (BID) and an inside diameter (SID1) prior to the insertion of the tube which is less than the tube outside diameter (TOD). Additionally, the sealing ring has at least one pair of diametrically opposing second portions, each second portion of the sealing ring comprising a recess between the two projections.

Abstract:
A magnetomechanical resonance element or marker strip with facilitated performance based on an amorphous magnetostrictive alloy ribbon is utilized in an electronic article surveillance marker. A curvature along the element's length direction is introduced during ribbon fabrication with a different radius of curvature, which increases the resonance performance with minimal loss in the magneto-mechanical circuit, and more particularly, in a marker utilizing a plurality of resonating elements or marker strips. A marker is fabricated utilizing the resonance element or elements and is utilized in an electronic article surveillance system.
Abstract:
The present invention provides novel assay methods for identifying compounds that may have both estrogen agonist and antagonist properties. In particular, the assay use cells comprising promoters having an AP1 site linked to a reporter gene. Compounds capable of inducing or blocking expression of the reporter gene can thus be identified. The compounds may be further tested for the ability to modulate the standard estrogen response, as well.
