Abstract: A nasal dilator is provided having one or more inserts that include one or more varied configurations that fit nasal passage anatomical configurations common to a group of potential users. The nasal dilator may include a circumferential force profile configured to vary at different points of contact along a circumference of the insert providing one or more dilation force magnitudes disposed at different locations around the circumference, wherein the one or more nasal inserts are shaped, sized, and configured based anatomical information of nasal passage surface features derived through an analysis of anatomical information from a group of potential users.

Abstract: A nasal dilation system has at least two sets of nasal dilators. Each set includes one or more nasal inserts having a mesh wall comprised of interconnected struts and openings. The mesh wall forms a cannula. The inserts are designed to engage with the inner surface of nasal passages. The pattern of struts and openings of a first set differs from a second set, resulting in different impact patterns on the inner surface of nasal passages, reducing repeated impact of the same inner surface portion across multiple sets of nasal dilators.

Abstract: A composition for waterproofing and inhibiting corrosion of silicon dioxide containing substrates, such as masonry structures. The composition is from about 7% by weight to about 60% by weight of an alkylalkoxysilane, including oligomers and mixtures thereof, having a molecular weight of from about 100 to about 1000, and a solvent for the silane which can be an aromatic or aliphatic hydrocarbon solvent or mixtures thereof, with the solvent being free of alcohol groups.
