Abstract: A radio frequency identification device (RFID) antenna structure includes electrically-conductive material. The antenna structure includes low effective resistance-material areas and high effective resistance areas in regions where there would be little current flow if there were more low effective resistance material. The high effective resistance areas may be spaces within the antenna structure in which there is substantially no electrically conductive material. Alternatively, high effective resistance material in the high effective resistance areas may have a non-zero lower electrical conductivity than the low effective resistance material in the low effective resistance-material areas. Conductive material for the antenna structure may include conductive ink. By reducing or eliminating the amount of conductive material in the high effective resistance areas, it will be appreciated that reduced-cost devices may be obtained.

Abstract: The invention relates to mammalian cell lines and transgenic mammals. More particularly, it relates to a method for producing a rat cell line, a method for producing a transgenic rat, a transgenic rat, a rat cell line, cells and tissue obtained therefrom and uses therefore. The cell line derived from a transgenic mammal comprises: (i) a conditional oncogene, transforming gene or immortalising gene or a cell cycle affecting gene; and (ii) a cell type specific promoter. They include a neuronal cell line in which the cell type specific promoter is an NF-L gene promoter, and a mammary cell line in which the cell type specific promoter is a MMTV gene promoter. The conditional oncogene, transforming gene or immortalising gene is preferably a SV40tsA58 gene.

Abstract: A Z-folded barrier cuff is provided to allow both sufficient lateral spacing of the barrier cuffs for the genitals in the front and for BM containment in the back as well as sufficient cuff height in the crotch area for good fit into the leg crease and good containment of body exudates. The barrier cuff is Z-folded by folding a first portion back upon itself such that a first segment and a second segment is formed. A second portion is folded laterally inwardly back upon itself such that a third segment is formed. Thus, the Z-folded barrier cuffs are properly laterally spaced in the crotch area and near the end edges while providing sufficient height to properly contain body exudates.

Abstract: Disposable paper products, such as paper toweling, are provided with an indicator means which is disposed on said disposable paper product in a discontinuous or combination discontinuous/continuous pattern. The indicator means gives a visually recognizable signal to a user that desirable properties of the disposable paper product are maintained, even after the disposable paper product has become wetted with a substantially transparent aqueous liquid. The wet gray scale difference for the disposable paper product of the present invention is at least about 64 gray scale units when the disposable paper product is wetted with a substantially transparent aqueous liquid.

Abstract: An embossed paper laminate having two laminae is provided. The laminae are joined such that there is at least one zone of the laminate wherein the peel strength of the laminate in that zone is greater than the peel strength of the laminate in other zones of the laminated paper product. The laminate is made by two close tolerance pattern rolls juxtaposed to form a nip. Each pattern roll has radially extending protuberances which contact the periphery of the other pattern roll intermediate its protuberances. The laminae are fed through the nip in face-to-face relationship and are embossed and adhesively joined to the other lamina by the radially extending protuberances. The laminating adhesive is supplied to the various zones of the laminated paper product at a level that is appropriate for providing the requisite peel strength for that zone.

Abstract: This invention relates generally to a novel directed metal oxidation process which is utilized to produce self-supporting bodies. In some of the more specific aspects of the invention, a parent metal (e.g., a parent metal vapor) is induced to react with at least one solid oxidant-containing material to result in the directed growth of a reaction product which is formed from a reaction between the parent metal and the solid oxidant-containing material. The inventive process can be utilized to form bodies having substantially homogeneous compositions, graded compositions, and macrocomposite bodies.In a preferred embodiment, a substance comprising a filler material and a solid oxidant, preferably an admixture of particulates, is coated onto at least a portion of the solid oxidant-containing material. Such a technique is particularly advantageous for forming relatively thick reaction product layers which might not otherwise develop to the desired thickness using the original "directed growth" embodiment.

Abstract: The invention relates to an absorbent structure (1) having a first layer which forms a mixture of absorbent gelling material particles (5), fibers, a second layer comprising liquid permeable substrate (7), and absorbent gelling material particles (9) attached to said substrate thus forming a laminate. The weight of the absorbent gelling material particles (5) in the mixed layer is not more than 70 percent, preferably not more than 60 percent of the weight of the mixed layer. The combined weight of the absorbent gelling material particles attached to the substrate (7), and in the mixed layer (5) is at least 80 percent, preferably at least 140 percent of the weight of fibers in the mixed layer (5). The laminate (7, 9) can be located on top of the mixed layer (5), and comprises an acquisition zone (15) of low basis weight of absorbent gelling material particles. The laminate may also be located below the mixed layer.

Abstract: This invention relates generally to a novel directed metal oxidation process which is utilized to produce self-supporting bodies. In some of the more specific aspects of the invention, a parent metal (e.g., a parent metal vapor) is induced to react with at least one solid oxidant-containing material to result in the directed growth of a reaction product which is formed from a reaction between the parent metal and the solid oxidant-containing material. The inventive process can be utilized to form bodies having substantially homogeneous compositions, graded compositions, and macrocomposite bodies. In a preferred embodiment, the reaction product may be chemically modified or a different reaction product may be coated thereon. Specifically, once a first reaction product is formed on a solid oxidant-containing material, the formed body may be exposed to a vapor-phase parent metal different from the first parent metal.

Abstract: A system that incorporates inertial sensor information into optical flow computations to detect obstacles and to provide alternative navigational paths free from obstacles. The system is a maximally passive obstacle detection system that makes selective use of an active sensor. The active detection typically utilizes a laser. Passive sensor suite includes binocular stereo, motion stereo and variable fields-of-view. Optical flow computations involve extraction, derotation and matching of interest points from sequential frames of imagery, for range interpolation of the sensed scene, which in turn provides obstacle information for purposes of safe navigation.

The caddy stringer is adapted to the detachable engagement of a restraint line to the diver and/or stringer extensions for gear and game, the vessel further including a connector at one end for towing on a seaway surface.

Abstract: A method for the determination of total carbon, calculated as carbon dioxide, present in aqueous solutions containing organic compounds and/or inorganic carbonates by mixing the aqueous solution with a solid reagent active at elevated temperature for the displacement of carbon dioxide from inorganic carbonates, contacting the mixture with oxygen at elevated temperature whereby carbon dioxide is produced by oxidation of organic compounds and by displacement from any inorganic carbonates present, drying the carbon dioxide so produced, separating the carbon dioxide from the oxygen by selective adsorption on a bed of particulate adsorbent which preferentially retards the passage of carbon dioxide, flushing the bed with inert gas to displace the oxygen, thereafter eluting the carbon dioxide by raising the temperature and reversing the flow of inert gas through the bed and finally measuring the eluted carbon dioxide.
