Abstract: A system and method for annotating written materials with phonetic information to indicate correct pronunciation is presented. The system and method of the present invention uses color and makes changes to the standard shapes of letters to indicate the phoneme a letter or group of letters represent. The system and method of the present invention does not add letters, remove letters, or alter the appearance of letters to an extent that would render the written materials unreadable or unrecognizable to a person unfamiliar with the system and method of the present invention. Thus, the system and method of the present invention preserves the overall appearance of written materials while providing additional information that allows a reader trained in the system and method of the present invention to correctly pronounce those written materials.

Abstract: Methods, systems, and media for providing media guidance are provided. In some embodiments, the method comprises: receiving a request to browse through related content; receiving a plurality of content clips, wherein each content clip corresponds to a portion of a corresponding content item; causing a first content clip to be presented; in response to determining that presentation of the first content clip has been completed, causing a second content clip to be presented; receiving a user input indicating a user preference related to the second content clip; in response to receiving the user input, requesting a third content clip based on the user preference related to the second content clip; receiving the third content clip, wherein the third content clip has been identified based at least in part on metadata associated with the second content clip and metadata associated with the third content clip; and causing the third content clip to be presented.

Abstract: A heliostat array having a variable field density for use in a concentrating solar power (CSP) plant. Heliostats are arranged into subgroups and configured to track the sun and reflect light to a receiver tower. Heliostats are deployed onto structures, wherein the structures can be arranged in rows separated by a service gap. The structures can comprise cross members that can be varied in size. By altering the size of cross members in a structure, heliostats in one row can be deployed farther apart or closer together than heliostats in a different row. Heliostat field density can vary with distance from the receiver tower, wherein heliostats close to the receiver are more tightly packed and heliostats further from the receiver are spaced farther apart.

Abstract: A self-monitoring transformer is disclosed. The transformer uses sensors embedded in the coils to determine the expected lifespan of the insulation, as well as other operating parameters, and communicates that information to an external system.

Abstract: A lens system for scanning a document positioned on a flat support. The lens system operates in cooperation with apparatus which scans a beam of illuminating light across the document and a scanning mirror, which directs reflected light from the illuminated document in a direction toward an array of photodetectors. The lens system is positioned between the scanning mirror and the photodetector array and includes a movable doublet lens and fixed doublet lens. The movable doublet lens collimates the light through the lens system, while the fixed doublet lens focuses an image of the scanned document portion upon the face of a photodetector array. A set of 6 correcting lenses are arranged symmetrically with respect to a plane of symmetry in a position between the two doublet lenses. A barrel cam and a follower arrangement is provided for moving the movable doublet lens in synchronism with the image scanning mirror, so that optical field flattening is achieved.

Abstract: A photographic apparatus having a lens movable along an axis for automatically focusing an object to be photographed is disclosed. The apparatus includes a rotatable sleeve controlled by electrical signals produced by photoreceptor means adapted to receive light emitted by the apparatus and reflected from the object. The sleeve effectuates the movement of the lens along an axis to bring the object into focus. The apparatus further includes assembly means, carrying the photoreceptor means, pivotably secured to the sleeve for adjusting the light received by the photoreceptor means by an amount corresponding to the rotation of the sleeve, thereby changing the electrical signals to maintain the object in focus.
