Abstract: Methods and systems for identifying content of interest. Accessed textual information is processed by at least one of character unification, phrase unification, and concept unification. A configured processor executes at least one predefined rule to determine whether the unified content includes certain types of information. Unified content that matches may be subject to further action such as alerts, encryption, logging, etc.

Abstract: A personal respiratory protection device that comprises a mask body and an exhalation valve that is secured to the mask body. The mask body includes (i) a flat central panel; (ii) a flat first panel joined to the central panel through a fold-line, seam weld, or bond, the fold-line, seam, weld or bond of the first panel being substantially coextensive with an edge of the central panel; (iii) a flat second panel joined to the central panel through a fold-line, seam, weld or bond, the fold-line, seam, weld or bond of the second panel being substantially coextensive with an edge of the central panel. At least one of the center, first and second panels includes filter media. The device is capable of being folded for storage with the first and second panels in at least partial face-to-face contact with a common surface of the central panel and, during use, is capable of forming, over the nose and mouth of the wearer, a cup-shaped air chamber having a face-contacting periphery.

Abstract: The invention provides an antenna system for operation near a ground plane, for example, at or near the surface of a body of water. The antenna system includes, for example, an array of filar elements attached to one or more spiral elements. The system also includes, for example, a buoyant support and/or housing for transporting the antenna to and/or maintaining the antenna at or near the surface of a body of water.

Abstract: An electron-emitting photocathode includes a base and a large number of projecting elements such as microscopic wires projecting from a surface of the base. The photocathode has high quantum efficiency, and hence can be used as the emitting element in a sensitive phototube.

Abstract: A toilet bowl illuminating apparatus of the type wherein a seat ring is pivotally mounted to a toilet bowl by a pair of spaced apart, co-axial hinge assemblies, has a light assembly, which is activated by a switch responsive to angular orientation, affixed in a cavity at the seat ring rear edge proximate the hinge axis, where the length of the light assembly body is resiliently reduced, so as to be gripped by spring forces, with the light being held to illuminate the toilet bowl interior when the seat ring is raised and deactivated when the seat ring is lowered.
