Abstract: A mounting device may include a top plate including a cone-shaped center portion, a flange coupled to the cone-shaped center portion, a number of apertures defined in the flange, and a number of fasteners engaged with the apertures to couple the top plate to a surface of a structure. The flange seals a bottom side of the top plate to the surface of the structure. The flange includes a seal coupled to the bottom of the flange. The cone-shaped center portion has a convex paraboloid shape. The flange includes at least one surface that is parallel to a surface of the structure, and a transition between the cone-shaped center portion and the flange forms an angle. The top plate has a diameter sufficient to displace a load greater than 50 pounds over the surface of the structure.

Abstract: Polymers, and particularly conventional commodity bulk polymers, are modified to have a surface activity of interest using a surface modifying polymer that includes a moiety that favors migration to the surface of the bulk polymer together with a moiety provides the activity of interest (e.g., biocidal, wettability modifying (hydrophobic or hydrophilic), resistance to radiant energy, providing a functional group for functionalizing the surface, etc.). The surface modifying polymer is combined with the bulk polymer, and, due to the presence of the moiety that favors migration, concentrates primarily on the surface of the bulk polymer such that the moiety that provides the activity of interest is located primarily on the surface of the bulk polymeric article which is produced. Advantageously, only a minimal amount (such as, e.g., about 2 weight %) of polymeric surface modifier is needed. Being able to achieve desired properties (such as biocidal activity, wettability modification, etc.

Abstract: The present invention is an apparatus to provide a virtual tennis net that can be placed on any convenient surface having two movable poles each having a light source dependent thereon; at least two scanning mirrors; at least two retroflectors; at least two beam splitters; at least two photo-detectors; and an audible or visible signal device that is actuated in response to interruptions of light falling on said photo-detectors such that when a the light beam is interrupted by a tennis ball, the beam is momentarily blocked and the signal to the photo-detector is interrupted, providing a signal that is used to trigger a light or sound signal that indicates the ball did not pass over the virtual net.

Abstract: A composition of matter containing a solution made from: from about 18 to about 70 wt % of a sugar; from about 2 to about 10 wt % of a water-soluble polysaccharide; from about 0.1 to about 1 wt % of a phosphate; from about 0.01 to about 1 wt % of a surfactant; and from about 18 wt % to remainder of water. A method for dust and sand abatement and erosion prevention by: providing the above solution, applying the solution to sand or dust particles wherein the solution binds to the particles; and allowing the solution to bind to the sand or dust particles and to dry thereby forming a hardened crust.

Abstract: A coating having an adhesive hydrophilic polymer and an amphiphilic additive. The amphiphilic additive has a hydrophilic chain, a biocidal functional group bonded to the hydrophilic chain, and a hydrophobic moiety bonded to the hydrophilic chain or to the biocidal functional group. A method of forming a biocidal surface by providing an article, and coating the article with the above coating.

Abstract: The present invention is directed toward a self-decontaminating surface coating, which when cured has a partially hydrophobic surface. The coating comprises a polymeric coating resin which, when cured, is hydrophilic. The coating also comprises a biocide, a germinating agent, and a hydrophobic micro/nano particulate material. The coating is suitable for application to ceramics, metals, and polymer substrates. Articles coated with the coating of the present invention are resistant to spores.
