Abstract: A nozzle including a plurality of moveable nozzles configured to transition between a first state in which streams produced by the nozzles combine to form a collective stream, or the appearance of a collective stream, and at least one second state in which the nozzles produce separate respective streams; and a drive mechanism configured to transition the nozzles between the first and second states.

Abstract: A light emitting diode (LED) light assembly apparatus includes a housing, a lens stack, and a power supply assembly. The lens stack comprises an LED array of a plurality of LED light sources and a lens positioned in the housing with respect to the LED array to diffuse and focus light transmitted from the plurality of LED light sources and, thereby, provide a light beam out from the housing, the lens being operable to diffuse the transmitted light before focusing the transmitted light. The power supply assembly is operable to supply power to the lens stack and, thereby, power the plurality of LED sources. A method for making the beam of light is also provided.

Abstract: The present invention provides a macroporous hyperhydroxy polymer formed from a monomer mixture of substantially similar fractions of functional acrylic monomers which are combined to form a compound having a polymer skeleton which provides a high number of hydroxyl sites. The result is a material which, when hydrated, has a pore size relative to oxygen and water which provides a high ratio of free water to bound water. When formed into contact lenses, the material exhibits oxygen permeability approaching that of a static layer of tears of equal thickness and water contents of 95% or greater. The polymer is also suitable for use as burn dressings, bandages, soil hydratants, surface treatments, lubricants and coatings, absorbents, transport membranes and the like.
