Abstract: An apparatus includes a valve and an actuator. The valve has a portion movably disposed within a valve pocket defined by a cylinder head of an engine. The valve is configured to move relative to the cylinder head a distance between a closed position and an opened position. The portion of the valve defines a flow opening that is in fluid communication with a cylinder of an engine when the valve is in the opened position. The actuator is configured to selectively vary the distance between the closed position and the opened position.

Abstract: A lamp with a head freely rotatable above a base is provided. Preferably both the head and base are made of several panels interconnected with hinges. The panels forming the head include a frame with tabs defining a slot for inserts. The inserts are transparent or translucent and bear decorative designs. A low heat highly efficient light bulb is used as a light source. The various elements are preferably shipped in a single box and are arranged and constructed so that they can be readily assembled to form the lamp without any tools required.

Abstract: A method of constructing graph abstractions using a computer is described. The abstraction is presented on a computer display and used by a human viewer to understand a more complicated set of raw graphs. The method provides rapid generation of an abstraction that offers an arbitrary composition graph of vertices into composite vertices, dispersing and marshaling of composite vertices, arbitrary hiding and showing of portions of the composition, and marking of points of elision.

Abstract: A method of full-text scanning for matches in a large dictionary of keywords is described, suitable for SDI (selective dissemination of information). The method is applicable to large dictionaries (hundreds of thousands of entries) and to arbitrary byte sequences for both patterns and sample streams. The approach employs Boyer-Moore-Horspool skipping, extended to pattern collections and digrams, followed by an n-gram hash test, which also identifies a subset of feasible keywords for conventional pattern matching at each location of a putative match.

Abstract: A method and apparatus providing full-text scanning for matches in a large dictionary is described. The invention is suitable for SDI (selective dissemination of information) systems, accommodating large dictionaries (104 to 105 entries) and rapid processing. A preferred embodiment employs a hardware primary test on a single commercially-available gate-array board hosted by a computer, in which a software secondary test is conducted. No delimiter cues such as spaces or punctuation are required.

Abstract: Index terms are drawn from text documents without the need for language-specific processes or training and are suitable as gists for the subject documents. Index terms are extracted on the basis of scores of constituent n-grams relative to n-gram counts in a corpus. A method of extracting joint index terms to represent a plurality of documents is also provided.
