Abstract: A nonwoven web having an advantageous bond pattern impressed by a bonding pattern on a roller is disclosed. The bonding pattern is selected to have a bonding area percentage from 6 to 14 percent, which provides a desirable level of bonding of filaments and/or fibers for mechanical strength, while retaining desirable pliability and/or liquid handling characteristics. The bonding area is also relatively highly dispersed, which provides for a relatively greater number of bonded areas for the selected bonding area percentage. The greater number of bonded areas is believed to provide improved structural integrity while still retaining pliability and/or liquid handling characteristics, and also provide for enhanced visual detail and complexity. The relatively highly dispersed bonding area is believed to be particularly effective for nonwoven web materials having three or more layers, with outer layers of polymeric filaments, and even more particularly, one or two outer layers of fine filaments.

Abstract: An optical component has an elongate length extending between first and second ends and a width transverse to and substantially smaller than the length and extending between first and second sides. The optical component includes a refractive portion disposed between the first and second sides and extending along the length between the first and second ends, and a plurality of separate reflective portions. At least one of the plurality of separate reflective portions is spaced from the refractive portion and extending along the length between the first and second ends.

Abstract: Implant devices for intravesical administration and local drug delivery. The device has a body which includes a hollow tube formed of a biocompatible material; at least one reservoir in the tube which contains a drug; and one or more apertures through which the drug can be released. The device is configured for minimally invasive insertion into a body cavity, such as the bladder. The hollow tube may be elastomeric to permit the device to be elastically deformed from its initial shape into an elongated shape for passage through a catheter, where following such passage the device can return to or toward its initial shape to facilitate retention of the device in the body cavity. The body may have a narrow, elongated shape effective to permit insertion of the drug delivery device through a catheter without necessarily deforming the body, yet include flexible projections which effect retention within the body cavity.

Abstract: A light emitting diode (LED) package comprising an encapsulant designed to improve color spatial uniformity in comparison to hemispherical encapsulants is described. In some embodiments, the encapsulant comprises a segment of a hemisphere as a lower portion and an upper portion of a second shape. In some embodiments this second shape is defined by a spline curve. The encapsulant improves color uniformity over a wide range of angles while only minimally affecting other attributes such as photometric polar distribution, extraction efficiency, and luminous intensity. Embodiments of the present invention can also utilize light emitting systems comprising such LED packages.
