Abstract: A utility distribution enclosure disclosed herein includes a container that defines an interior space that is interior of the container, a detent formed about inner surfaces of the container, and a partition positionably releaseably engageable with the detent to subdivide the interior space into a first subspace and a second subspace selectingly sized to accommodate a first utility interface and a second utility interface by positioning of the partition, in various aspects. The partition blocks interactions between the first utility interface and the second utility interface.

Abstract: A method for dynamically registering multiple patterned layers on a substrate (3) comprises: depositing a first layer on the substrate; printing a first pattern (20) on the first layer; depositing a second layer on the first pattern; and printing a second pattern on the second layer while dynamically detecting the first pattern to align the second pattern with the first pattern.

Abstract: A projection apparatus (10) has an illumination section with a light source (20) providing a substantially unpolarized illumination beam of multiple wavelengths. A multiple wavelength polarizer polarizes the substantially unpolarized illumination beam to provide a substantially polarized illumination beam of multiple wavelengths. A uniformizer conditions the substantially polarized illumination beam of multiple wavelengths to provide a uniformized polarized beam of multiple wavelengths. A color scrolling element provides a repeating, scrolled sequence of colors from a set of colors, thereby providing first, second, and third component wavelength illumination.

Abstract: An apparatus for obtaining radiant energy from a polychromatic radiant energy source has a spectral separator with a first curved surface concave to the incident radiant energy and treated to reflect a first spectral band toward a first focal region and to transmit a second spectral band and a second curved surface concave to the incident radiant energy and treated to reflect the second spectral band toward a second focal region. The first and second curved surfaces are optically positioned so that the first and second focal regions are spaced apart from each other. There are first and second light receivers, wherein the first light receiver is disposed nearest the first focal region for receiving the first spectral band and the second light receiver is disposed nearest the second focal region for receiving the second spectral band.

Abstract: An apparatus for obtaining energy from a polychromatic radiant energy source has a light concentrator for concentrating and redirecting incident radiant energy, having an optical axis, and a spectral separator disposed along the optical axis, apart from the light concentrator and in the path of concentrated, redirected radiant energy. The spectral separator has a first planar surface treated to reflect a first spectral band of light toward a first focal region and to transmit a second spectral band and a second planar surface spaced apart from the first planar surface and oblique with respect to the first planar surface. The second planar surface is treated to reflect the second spectral band back through the first planar surface and toward a second focal region spaced apart from the first focal region. First and second light receivers are disposed nearest each respective focal region for receiving the first and second spectral bands.

Abstract: An optical apparatus (10) for stereoscopic viewing has a first optical channel with a first display (12l) generating a first image and a first viewing lens assembly (22l) producing a virtual image, with at least one optical component of the first viewing lens assembly truncated (26l) along a first side. A second optical channel has a second display (12r) generating a second image and a second viewing lens assembly (22r) producing a virtual image, with at least one optical component of the second viewing lens assembly truncated (26r) along a second side. A reflective folding surface is disposed between the second display and second viewing lens assembly to fold a substantial portion of the light within the second optical channel. An edge portion of the reflective folding surface blocks a portion of the light in the first optical channel. The first side of the first viewing assembly is disposed adjacent the second side of the second viewing lens assembly.

Abstract: A projection apparatus (10) has an illumination section (68) that provides at least a first, a second, and a third component wavelength illumination. At least two component wavelength modulating sections accept and modulate the component wavelength illumination to provide a modulated component wavelength beam. Each component wavelength modulating section has a portion of a monochrome transmissive liquid crystal modulator panel (118) that has been segmented into at least a first, a second, and a third spatially separate portion. A component wavelength polarizer directs substantially polarized light to the corresponding portion of the monochrome transmissive liquid crystal modulator panel. An illumination path Fresnel lens focuses incident illumination from the component wavelength polarizer through the corresponding portion of the monochrome transmissive liquid crystal modulator panel. An analyzer conditions the polarization of the modulated component wavelength beam.

Abstract: A projection apparatus (10) has an illumination section that provides first, second, and third light sources (20) for providing first, second, and third illumination beams. First, second, and third component wavelength modulating sections modulate the corresponding illumination to provide first, second, or third modulated component wavelength beams respectively.

A component wavelength polarizer in the path of the component wavelength illumination directs substantially polarized light to the corresponding portion of the monochrome transmissive liquid crystal modulator panel. An illumination path Fresnel lens focuses incident illumination from the component wavelength polarizer through the corresponding portion of the monochrome transmissive liquid crystal modulator panel.

Abstract: An alignment viewer apparatus (40) for assessing optical path alignment of a stereoscopic imaging system (10), the apparatus (40) having a left reflective surface (42l) for diverting light from a left viewing pupil (14l) toward a beam combiner (44) and a right reflective surface (42r) for diverting light from a right viewing pupil (14r) toward the beam combiner (44). The beam combiner (44) directs the diverted light from left and right viewing pupils (14l and 14r) to form a combined alignment viewing pupil (36), allowing visual assessment of optical path alignment thereby.

A circular polarizer (90) is disposed at a position between viewing pupils (14l, 14r) and the beamsplitter (16), minimizing glare due to stray light reflection from the curved mirror surface.

A beamsplitter is disposed between the focal surface and the center of curvature of the curved mirror.
