Abstract: The present invention introduces the use of a carbon nanotube-based material in the production of phased array patch antennas of various shapes and sizes including slot and spiral patch antennas. The use of this material provides the ability for the antennas to withstand high-intensity shock vibrations and other intense disturbances and continue emitting phased array signals. Furthermore, the use of this material for patch antennas allows for the alteration of the desired frequency and directional degree of interest by simply energizing various elements within the carbon nanotube-based material.

Abstract: A method for designing a flat device to be thermoformed into a shape-retaining non-flat device using a mold is provided. The flat device comprises two concentric annular layers: a carrier layer, having an outer radius (RCout) and a carrier layer width (WC); and a support layer having a support layer width (WS). The support layer is mechanically attached to the carrier layer wherein an inner distance (GAP) is formed between an inner edge of the carrier layer and an inner edge of the support layer. The method comprises obtaining predetermined values for the outer radius of the carrier layer, the support layer width and the inner distance, obtaining a geometry of the mold, and obtaining material properties of the support layer and the carrier layer. The method further comprises performing at least two simulations of thermoforming a simulated flat device into a non-flat device using the mold, based on the obtained predetermined values, material properties, and geometry of the mold for at least two different carrier layer widths. The method further comprises determining a circumferential strain at an outer edge of the support layer in each of the simulated non-flat devices. The method further comprises determining, based on the determined circumferential strains, a linear relation between the circumferential strain and a dimension ratio defined by ratio = ( W C - ( W S + GAP ) ) / R Cout . The method further comprises determining (1070), based on the determined linear relation, a value (ratioMNB) of the dimension ratio for which the strain is zero and determining, from the dimension ratio for which the strain is zero, the width of the carrier layer in the flat device as W C = ratio * R Cout + W S + GAP .

Abstract: A method of forming a three-dimensional object is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling the build region with a polymerizable liquid, the polymerizable liquid including a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from the first component; (c) irradiating the build region with light through the optically transparent member to form a solid polymer scaffold from the first component and also advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object, and containing the second solidifiable component carried in the scaffold in unsolidified and/or uncured form; and (d) concurrently with or subsequent to the irradiating step, solidifying and/or curing the second solidifiable component in the three-dimensional intermediate to form the three-dimensional object.

Abstract: The invention provides a method for producing embedded contact lenses involving a mold set in a two-curing-step process and a fast-curing SiHy lens formulation. The mold set consists of three mold halves, one of which is used twice, the first time for molding an insert from an insert-forming composition and the second time for an embedded contact lens with the molded insert embedded therein from the fast curing SiHy lens formulation that comprises a N,N-dialkylacrylamide, a hydrophilic (meth)acrylamido monomer, and a polysiloxane vinylic crosslinker and being free of any siloxane-containing vinylic monomer.

Abstract: The invention provides a method for producing embedded diffractive contact lenses involving use of a mold set in two-curing steps. The mold set consists of three mold halves, one of which is used twice, the first time for molding a diffractive insert and the second time for an embedded contact lens with the molded diffractive insert embedded therein. The twice-used mold half has been treated with a corona plasma or a vacuum UV in a central circular area having a diameter equal to or smaller than the diameter of the insert to ensure that the molded insert consistently adheres to the twice-used mold half, even though the other mating insert mold half for molding the diffractive insert has a great tendency to bind strongly the molded insert due to the diffractive structure on its molding surface.

Abstract: A mandrel for holding and positioning an intraocular lens blank during manufacturing includes a shank portion having a central axis and a lens blank holding section configured to hold the lens blank. The holding section includes a central cavity formed concentrically with the central axis of the mandrel. Projections are formed on a surface of the central cavity and are configured to support a first surface of the lens blank at a fixed distance from the surface of the central cavity. A ring fits within a peripheral portion of the central cavity to hold a second opposing surface of the lens blank. A method for making an intraocular lens using the mandrel includes filling the space formed under the first surface of the lens with a liquid, such as water, freezing the liquid, and then machining and/or milling the second surface of the lens blank.

Abstract: The invention is directed to a cast molding method for making embedded hydrogel contact lenses. The method comprises a step of actinically curing a lens-forming composition in specific locations in molding assemblies each of which is formed from one male lens mold half and one female insert mold half having a molded insert adhered thereon and comprises the lens-forming composition filling a gap between the back surface of the mold insert and the molding surface of the male lens mold half. This tack curing step ensures molded inserts adhered through multiple spots to the molding surface of each male lens mold halves which in turn will be used together with a female lens mold half in cast-molding of a lens forming composition to form an embedded silicone hydrogel contact lens.
