Abstract: A method is described for forming a permanently supported thin lamina using decomposable adhesives between a lamina and a temporary support element. The temporary support element may be bonded to a first surface of the lamina. A permanent support element may be applied to a second surface of the lamina, and the temporary support element debonded from the lamina by decomposing the adhesive.

Abstract: A free-standing metallic article, and method of making, is disclosed in which the metallic article is electroformed on an electrically conductive mandrel. The mandrel has an outer surface with a preformed pattern, wherein at least a portion of the metallic article is formed in the preformed pattern. The metallic article is separated from the electrically conductive mandrel, which forms a free-standing metallic article that may be coupled with the surface of a semiconductor material for a photovoltaic cell.

Abstract: Compositions and methods useful for the removal of polymeric material from substrates, such as electronic devices are provided. These compositions and methods are particularly suitable for removing polymer residues from electronic devices following plasma etch processes.

Abstract: The invention relates to a variable optical attenuator constructed as a Mach Zehnder planar lightwave circuit, particularly including a channel waveguide support structure for heat isolation and stress relief to reduce polarization dependent loss (PDL) and power consumption in the device. Power reduction trenches comprise longitudinal segments having small stress relief pillars of cladding material left in between them in the etching process. The waveguides of the MZI are supported by a main pillar structure and integral stress relief pillars which remain after removal of the trenches. The waveguide is surrounded by air on three sides for improved heat isolation. The performance of the present invention shows substantial improvement in PDL and extinction ratio over the prior art continuous trench design, and also, to a smaller degree, over the case where power reduction trenches are not used at all.

Abstract: The present application relates to a method of fabricating planar circuits using a photolithographic mask set, to the photolithographic mask set, and to a planar circuit fabricated with the photolithographic mask set. The instant invention involves separating a photolithographic mask into two parts, namely, a master mask and one or more slave masks. The master mask and the one or more slave masks form a photolithographic mask set that is used iteratively to fabricate the planar circuits. In particular, the master mask is used as a template to provide the general layout for the planar circuit, while each slave mask is varied to tune and/or tailor the planar circuit. Since only a small portion of the planar circuit is redesigned and/or rewritten as a new mask (i.e., the slave mask), the instant invention provides a simple and cost effective method for optimizing planar circuits.

Abstract: In accordance with one aspect of the present invention, an interactive data identification and recall system is provided which avoids the need to encode additional data into the real-time media broadcast stream/system. In addition, the system can eliminate the need to store the entire show on an end user device, such as an ITV, digital TV, HDTV, smart set-top box or other appliance, and it affords the end user a way to continue watching a show uninterrupted and yet at some later time, recall data corresponding to a scene that interested them.

Abstract: This container is a unique self-dosing and dispensing container. Through the use of a one-piece, self-aligning valve which moves from one position of closing a dispensing opening to a position of opening the dispensing opening and simultaneously closing the opening between the container and the chamber which contains the dispensing opening. The valve is operated by a change in pressure within the container. The change in pressure in the container is induced by flowing an excess of fluide from the container so as to cause a negative pressure. There are various techniques for creating a negative pressure in the container, including the use of a bellows built into the container and a squeezing of the sidewalls of the container.
