Abstract: A stent has a tubular body with longitudinal struts interconnected by multi-bar linkages. The linkages comprise a pair of circumferential extending links, a pair of axial links and a pair of spaced hinges located between the circumferential links and the axial links. The struts inhibit foreshortening of the body and relative rotation between the links in the linkages, permitting radial expansion. The links are plastically deformed as they are expanded to maintain the expanded diameter.

Abstract: An apparatus and method for simultaneously taking measurements that are used for determining PMD vectors. This reduces the time interval over which all measurements are taken and reduces inaccuracy caused by PMD variation during the time measurement interval. The apparatus and method may be used in conjunction with any technique for calculating PMD, such as the Poincare Sphere Technique or Jones Matrix Eigenanalysis. The apparatus simultaneously produces multiple light beams. To distinguish each light beam from the others, each beam is given a distinct modulation. All the beams are then combined and passed through the optical device under test. A polarization measuring device then measures the output polarization of the combined beam and outputs one or more composite electrical signals that describe the Stokes components of the output polarization of the combined beam and that have the same modulations present in the original combined beam.

Abstract: A primer composition for radiation curable inks comprising 75-99.99% water, 0.01-20% of a silane coupling agent having the general formula: ##STR1## and 0.

Abstract: A method for decorating a vitreous article, in particular, a glass substrate, comprising applying to the glass in a predetermined design a radiation curable ink composition which is (i) operable when cured to bond to glass, and (ii) strippable from the glass upon exposure to alkali, and curing the ink on the glass by exposing it to the radiation by which it is curable, thereby bonding the ink to the glass; and related compositions; as well as a method for stripping the decorative indicia from glass upon exposure to alkali, and the related compositions.
