Abstract:
The technology provides an optical system for converting a source of projected light to uniform light for a liquid crystal on silicon microdisplay in a confined space, such as in a near-eye display device. The optical system may include a first microlens array, a second microlens array, and a polarizer device disposed between the first microlens array and the second microlens array. The near-eye display device having first and second microlens arrays may be positioned by a support structure in a head-mounted display or head-up display.
Abstract:
In embodiments of a multiple waveguide imaging structure, an imaging structure includes a first waveguide for see-through viewing of an environment at a first field of view, and includes a second waveguide for see-through viewing of the environment at a second field of view. The first and second waveguides each include a polarizing beam splitter to reflect light that enters at a first polarization orientation angle in the respective first and second waveguides, and the polarizing beam splitters pass through the light that enters at a second polarization orientation angle. The imaging structure also includes a polarization switch to rotate the polarization of the light through the first and second polarization orientation angles.

Abstract:
In embodiments of waveguide optics focus elements, an imaging structure includes a waveguide for viewing of an environment that is viewable with the imaging structure. The waveguide transmits light of a virtual image that is generated to appear as part of the environment for augmented-reality imaging or virtual-reality imaging. The imaging structure also includes one or more focus elements that are integrated in the waveguide and switchable to focus the virtual image at a focus depth that approximately correlates to a focal distance of the environment. The focus elements can each be implemented for a different focus depth of the virtual image, and the focus depth is adjustable based on a combination of the focus elements being switched-on or switched-off.
Abstract:
In embodiments of eyebox adjustment for interpupillary distance, a first optical lens receives light of an image from a display optic at a projected orientation of the light, and the first optical lens deviates the light of the image by a deviation angle from the projected orientation of the light. A second optical lens receives the light of the image from the first optical lens at the deviation angle, and the second optical lens alters the deviated light of the image back to the projected orientation of the light for viewing the image. Left and right eyeboxes align with respective left and right eyes that view the image, and a distance between the left and right eyeboxes approximately correlates to an interpupillary distance between the left and right eyes. The light of the image can be laterally shifted to increase or decrease the distance between the left and right eyeboxes.
Abstract:
This invention relates to conjugates of the Vi polysaccharide of S. typhi with the carrier Pseudomonas aeruginosa recombinant exoprotein A (rEPA), and compositions thereof, and to methods of using of these conjugates and/or compositions thereof for eliciting an immunogenic response in humans, including responses which provide protection against, or reduce the severity of, S. typhi bacterial infections. The conjugates, and compositions thereof, are useful as vaccines to induce serum antibodies against S. typhi and are useful to prevent and/or treat illnesses caused by S. typhi.
Abstract:
A system operating on at least one computer for displaying planning information associated with a supply chain includes an enterprise model, a planning engine, and a presentation interface. The enterprise model represents a supply chain that involves a plurality of products and resources. The planning engine uses the enterprise model to generate planning information for the supply chain according to one or more specified constraints and one or more optimization criteria. The presentation interface generates a first visual display for selected planning information. The first visual display includes a cashflow report providing a net present value for one or more products in the supply chain. Each net present value reflects revenues and expenses associated with a corresponding product according to time periods in which the revenues and expenses occur.
Abstract:
A desk chairmat includes a semi-rigid and substantially planar member of solid plastic material, the chairmat having four side edges with a lip portion extending from one of the side edges, an upper side of the chairmat having a substantially smooth upper surface. At least a first handle attached to or formed integrally with the chairmat along one of the side edges of the chairmat.
Abstract:
Methods and compositions are provided for cloning and expression of serum opacity factor of Streptococcus pyogenes genes. The portion produced by the recombinant DNA techniques described herein may be employed in qualitative and quantitative testing for high density lipoprotein, as a fibronectin binding factor and for the regulation of high density lipoprotein in a mammal. The gene may further be employed as a molecular probe for accurate identification of opacity factors from various strains of Streptococcus pyogenes.
