Abstract: A photovoltaic cell has a photosensitive substrate, a plurality of fingers in ohmic contact with the substrate, and a plurality of pads on the substrate. The plurality of pads effectively form a plurality of discontinuous busbars. Two of the fingers extend from a first pad of the plurality of pads. Specifically, a given one of the two fingers (“given finger”) may connect with a second pad of the plurality of pads. This given finger may have an inter-pad portion between the first and second pads. The cell further has a tab at least partially covering the inter-pad portion of the given finger.

Abstract: The present invention relates to a method for providing nonwoven polypropylene barrier composite fibrous structures with a surface that is both hydrophobic/alcohol repellent and durable to water/alcohol exposure. The method is based on the incorporation, into the nonwoven polypropylene barrier composite fibrous structure, of synergistic combinations of a new generation of non-telomer based fluorinated polymers with non-ionic hydrophobic waxes. When extruded with the polypropylene, these products result in a durable hydrophobic and alcohol repellent surface that is highly desirable to enhancing the utility of the nonwoven polypropylene barrier composite fibrous structures in a wide range of applications and products, ranging from medical to various construction applications.

Abstract: A photovoltaic cell has a photosensitive substrate and a plurality of fingers in ohmic contact with the substrate. At least one of the fingers has an average width of less than about 95 microns. The cell also has a plurality of busbars in ohmic contact with the fingers. At least two of the busbars that are spaced less than about 38 millimeters apart intersect the at least one finger (i.e., the finger(s) having an average width of less than about 95 microns).

Abstract: A mechanism for extending and supporting a high-lift device relative to an airfoil has a pair of support ribs coupled to the airfoil. A carrier track is pivotally coupled to the high-lift device and positioned between the pair of support ribs. The carrier track has a slot opening along a lower length thereof. A gear rack is coupled within the slot opening. A pinion gear is positioned between the support ribs and below the carrier track. The pinion gear engages with the gear rack for extending the high-lift device relative to the airfoil. A plurality of rollers is rotateably coupled to the support ribs and in bearing contact with the carrier track. At least one roller is positioned above the carrier track and a second roller is positioned below the carrier track. The second roller is positioned concentrically with the pinion gear.

Abstract: A method of producing calcium chloride including first forming a slurry of solid calcium oxide in an aqueous solution of calcium chloride, and then contacting the slurry with hydrochloric acid to convert at least a portion of the calcium oxide into calcium chloride.

Abstract: Video components attributable to ambient lighting in a stream of digital images of a scene illuminated by both ambient and active sources are eliminated in each image frame, leaving only video components attributable to the active source. The spectrum of the active source is encompassed by the ambient source, and spectral filtering defines a primary channel comprising video components in a primary spectrum encompassing both active and ambient lighting and a secondary channel comprising video components in a secondary spectrum encompassing only ambient lighting. The pixels of the secondary channel are scaled by a factor correlating the spectral reflectances of the primary and secondary spectra, and the scaled secondary channel is subtracted from the primary channel to produce an ambient corrected image. The pixels of the ambient corrected image are further scaled to compensate for spectral filter bleeding of the active source into the secondary channel.

Abstract: The present invention relates to a family of neuronal nicotinic acetylcholine receptors comprised of neuronal agonist and non-agonist binding subunits, and DNA sequences encoding such subunits.

At least one of the lenses includes an aspheric surface and an image distortion of the lens system is less than about five percent at a maximum field angle. A furthest point of the aspheric surface is positioned within a distance less than about fifty percent of a diagonal dimension of an associated imager.

Abstract: The leaf guard for gutters is an elongated sheet of enamel coated aluminum adapted to fit over the rain gutter on a house in a manner that directs water flow from the roof into the gutter while preventing leaves and other debris from entering the gutter. In a first embodiment, the guard is formed into a planar section that is secured to a roof, a curved nose section extending from the planar section, a trough under the curved section and a cornered lip extending from the trough to secure the device to the outer rim of a gutter. In a second embodiment, the guard is formed into a planar section, an inwardly bent connection section that is connected to the inner rim of a gutter, and a curved nose section that hangs over the outer rim of the gutter. The guard also has rows of elongated slits in the planar section that permit some water to drip through to prevent bees and other insects from nesting beneath the device.

Abstract: Apparatus for varying inlet lip geometry of a inlet formed at forward end portion of a jet engine housing. In one embodiment, the apparatus includes a variable camber skin portion hingedly coupled to the forward end portion of the housing. The apparatus also includes a linkage assembly coupled to the forward end portion and the skin portion. The linkage assembly operates to rotate the skin portion relative to the forward end portion and to alter a curvature of the skin portion to thereby configure the skin portion into a corresponding one of a plurality of configurations. The plurality of configurations include at least a first configuration and a second configuration. In the first configuration, the skin portion forms a rounded inlet lip portion extending forwardly of the inlet. In the second configuration, the linkage assembly and the skin portion are retracted within a recessed area in the housing to form an aerodynamically smooth outer surface of the housing.
