Abstract: Disclosed herein are three-dimensional free space imaging systems and related methods employing a dynamic stereoscopic image projection system in combination with a optic module comprising a doublet of Fresnel lenses. The dynamic projector systems calculating derived flat image information for each projector based upon inputted stereopair images and information regarding the projector elements and optic module. In preferred embodiments of the present invention, the projection system uses an image computational device that employs a neural network feedback calculation to calculate the appropriate flat image information and appropriate images to be projected on the screen by the projectors at any given time.

Abstract: Three-dimensional imaging without parallax barriers or specialized eye gear, and without attendant loss of resolution, is provided by a display that produces dynamic images for display on at least two stacked electronic transmissive displays to create a continuous 3-D image field in a large viewing area or in multiple viewing areas. The images on each display are derived from stereoscopic image sources corresponding to both eyes of a viewer, and the derived images act as a mask for each other causing 3-D perception. The derived images are processed by summing the predicted image data, comparing the predicted image data to the desired stereopair, and minimizing the error. In preferred embodiments, the processing can be performed by an artificial neural network. A viewer may be presented with different aspects of an image as their viewing position changes to allow the viewer to perceive various perspectives of an image in dynamic fashion.

Abstract: Disclosed herein are three-dimensional projection systems and related methods employing two electronically controlled projectors and a retro-reflective screen. The retro-reflective screen produces a known non-linear light reflection pattern when images are projected thereon.

More than two projectors can be employed to produce multiple aspect views, to support multiple viewers, and the like. In another embodiment, the projection system includes a digital camera that provides feedback data to the image computational device.

Abstract: The present invention describes a high yield and simplified method of preparing phenols and carbonyl compounds, such as acetaldehyde, through the catalytic decomposition of aromatic hydroperoxides. The synthetic process generally consists of decomposing hydroperoxides under a positive gas atmosphere and at an elevated temperature (80 to 100° C.) in the presence of a catalytic amount (0.01-0.8 mass percent (%)) of an anionic surface-active agent of the formula R—OSO3M or R—OP3Z2, where “M” is Na or K, where “Z” is Na, K or an alkyl groups containing between ten and fourteen carbons (C10-C14) and where “R” is an alkyl group consisting of between ten and fourteen carbons (C10-C14).

Abstract: The present invention is directed to a method of providing enhanced molecular stability to hydrocarbons, such as the various oils, lubricants, fuel and rubbers typically used in internal combustion engines. The invention generally comprises inhibiting the liquid phase oxidation of hydrocarbons by atmospheric oxygen at elevated temperatures through the micro-addition of non-toxic of alkyl organic additives. The alkyl organic additives are anionic surface active agents (ASAAs) of the general formula R—OSO3M or R—OP3Z2, where “M” is Na or K, where “Z” is Na, K or an alkyl group containing between ten and fourteen carbons and where “R” is an alkyl group consisting of between six and sixteen carbons. The additives are generally used in quantities from 0.01 to 10 mass percent, at temperatures between 70°-170° C. and in the presence of an aromatic solvent.

Abstract: The method and system of the present invention displays autostereographic images without parallax barriers or loss of resolution. A stereopair is processed and sent to a distant display and one or more transmissive displays placed in front of it. Each display has a calculated images containing at least some of the image information destined for both eyes of a viewer. Each display acts as a mask for the other displays. The processing of the stereopairs to produce calculated images comprises summing the predicted image data, comparing the predicted image data to the desired stereopair, and minimizing the error. In a preferred embodiment, this processing is performed by an artificial neural network. A spatial mask, such as a diffuser, can be placed between displays to suppress Moiré patterns.

Abstract: Disclosed herein are three-dimensional projection systems and related methods employing liquid crystal display panels and a phase screen to project a true three-dimensional image of an object. Certain embodiments of the projection systems can include an imaging system capable of projecting “amplitude hologram” images onto a phase screen to produce a viewable three-dimensional image. The imaging systems disclosed use at least one liquid crystal display panel, an image generation system for calculating flat image information and for controlling the liquid crystal panels, and a phase screen. The screen has regular “phase” information recorded on it, which can be a known phase-only or phase-plus-amplitude hologram that is not dependent on three-dimensional object to be projected.

Abstract: A holographic universal display according to the present invention uses reflective lighting for a liquid-crystal panel. The system comprises at least two waveguide holograms in a matched configuration that redirects incident light beams as diffracted beams so that the beams passing out of the display are targeted towards the viewer. That is to say, light beams that are incident to the display at large angles, over a wide range, with respect to normal are redirected into a set, narrow range of angles close to the required angle for optimal viewing. The required angle for optimal viewing is nominally perpendicular to the plane of the display (i.e., normal), but is optionally selectable (by design of the holograms) to be an angle varies from the strict perpendicular.
