Abstract: The present disclosure provides a wiper blade for cleaning a vehicle surface comprising an elongated, rubber-elastic wiper strip provided with respective longitudinal grooves on corresponding opposite long sides for securing to a mounting structure and with a wiper surface with an array of longitudinal microfeatures for contact with a surface wherein each microfeature is substantially rectangular in cross-section, an elongated spring-elastic mounting structure having corresponding slots and rails to engage the longitudinal grooves of the wiper strip, and a connection device for a wiper arm or handle connected to the middle portion of the mounting structure. The microfeatures replace a single wiping edge with multiple wiping edges to reduce noise, improve durability, and enable simplification of the wiper blade design. The wiper surface may have two sides that alternately contact the surface or a single side that maintains continuous contact during wiping motion in both directions.

Abstract: An antenna system comprises an antenna feed support and a driver. The antenna feed support is configured to mount a circularly polarized antenna feed to an antenna dish to extend outward along a longitudinal axis of the circularly polarized antenna feed with respect to a reflective surface of the antenna dish. The driver is configured to rotate the circularly polarized antenna feed to adjust alignment between the circularly polarized antenna feed and a remote antenna. The driver can rotate the circularly polarized antenna feed mechanically, electrically or both to adjust alignment between the circularly polarized antenna feed and a remote antenna to reduce cross-pol discrimination at the circularly polarized antenna feed.

Abstract: The invention discloses spray-dried compositions for inhalation and methods for preparing such powder compositions. The compositions of the invention are produced by spray-drying taurine under conditions that (i) retain the physical and chemical stability of the composition during spray drying and upon storage, (ii) protect the powder composition from aggregation and (iii) provide particles suitable for aerosolization.

Abstract: The invention relates to methods and devices for detecting the presence of a particle of interest (hereinafter an analyte particle) in a fluid. A detection device exemplary of the present invention filters a sample of the fluid to remove particles larger than the analyte particles. A reagent solution, containing reagent particles smaller than the analyte particles, is then added to the sample. The reagent particles will react with the analyte particles, if any are present, to form reagent-analyte complexes which are larger than the analyte particles. The sample is then filtered a second time to remove particles the same size as or smaller than the analyte particles. The sample is then tested for the presence of reagent-analyte complexes to detect the presence of the analyte particle in the fluid.

Abstract: A load bearing grab bar to be used in public and household restrooms to aid elderly or handicapped people in lowering or raising themselves from a toilet or wheelchair. The grab bar is attached to the baseboard of the wall or an existing handrail, and has an adjustable support leg to provide better stability when weight is applied. The grab bar rotates from a vertical stored position to a horizontal in-use position to allow for better and safer mobility around home bathroom or public toilet stall.

Abstract: Label assemblies are produced which obscure confidential information that is part of each label assembly, while allowing ready exposure of the confidential information in a tamperproof manner. A web of label components having a face ply with a top surface, underlying pseudo adhesion layers, an underlying image ply, an underlying adhesive layer, and a bottom release paper carrier ply are acted upon to non-impact print a security pantograph and readable indicia on the web face ply, and with an impact element generate a confidential information image on the image ply, which image is not visible from the face ply. Labels are die cut out of the web and matrix material formed by die cutting is removed so that the web then includes a bottom release paper carrier ply with a plurality of spaced labels, each having a confidential information image. The labels may be applied to a mailer or other substrate.
