Patent EP-0370778-A2 (EP)
Inventor: NUNBERG GEOFFREY D
IPC: G06F17/27
Filed: 1989-11-21
Abstract: A technique for processing natural language text uses a data structure that includes structure data in the text data. The structure data indicates an autonomous punctuational structure of the text, a punctuational structure that is independent of the lexical content of the text and therefore can be manipulated without considering the meaning of the words in the text. The data structure can be a tree in which each node has a textual type such as a paragraph, sentence, clause, phrase, or word. The data structure could alternatively be parallel data sequences, one with codes indicating the text's characters and the other with codes indicating textual types. The data structure is produced and maintained using a grammar of textual types, indicating for each textual type the textual types of units into which it can properly be divided. During editing, a text sequence is generated by applying rendering rules to the data structure, and the text is presented to the user based on the text sequence. Prior to generating the text sequence, information relating to punctuational features is propagated through the data structure. User signals requesting editing operation are applied to modify the data structure using operations rules, and the user's pointing or selecting signals are mapped onto the data structure. The modified data structure is checked with the grammar of textual types to ensure that it has an autonomous punctuational structure. A modified text sequence is then generated, and a modified text is displayed based on it.

Abstract: The invention is for a flat electrical heating resistance element, so called foil elements. Elements according to the invention can be used for many purposes, however, it is specially intended for use as heating elements for water beds. The object of the invention is to minimize the electromagne­tic fields caused by the elements. The influence of such magnetic fields on humans is on the whole unknown why there is a common desire that the strength of these magnetic fields shall be as low as possible in order to minimize effects, if any. Heating elements according to the invention have elec­trical resistance wire or band placed in loops on a plastic foil surface, whereby the loops have four with each other parallel conductors, electrically connected so that in any given moment the direction of the current in the two outer conductors are in the same direction and in the two inner conductors in the same direction opposite to the outer con­ductors.

Abstract: A polyarylene sulfide resin composition comprising a composition obtainable by a reaction of a polymer composition comprising 
(A) 100 parts by weight of a polyarylene sulfide resin, 
(B) 0.1 to 40 parts by weight of a monomer having one or more ethylenic unsaturated bonds and 
(C) 0 to 40 parts by weight of an unsaturated poly­ester. In the polyarylene sulfide resin composition of the present invention, a polymer produced by polymerization of the monomer or the monomer and unsaturated polyester, as compared with a resin composition wherein said polymer is simply blended, is in a state wherein it is uniformly mixed with the polyarylene sulfide resin and if necessary a filler. In other words, said polymer is uniformly dispersed in and mixed with the polyarylene sulfide resin to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions. Further, the amount of said polymer added to the polyarylene sulfide resin is so proper that an excellent-­performance resin composition to which an adhesive property of paint film (paintability) has been given, is obtained without a large reduction in the excellent properties of the polyarylene sulfide resin.

Abstract: An automatic gain control (AGC) for a demodulator which receives digitally modulated burst signals time-­serially from a plurality of terminals. The AGC has a series connection of a variable attenuator and a limiter that precedes a demodulator. The variable attenuator is controlled such that when a burst signal is absent, the noise power level inputted to the limiter coincides with a predetermined reference value, whereby when burst signal is present, the limiter controls the burst signal to a predetermined level. As a result, when burst signals greatly differ in level from one another, they are controlled to he predetermined level in their preamble word portions. This insures stable demodulation of data signals.

Abstract: A data base management system encodes information (such as the field values of a database record, or the words of a text document) so that the original information may be efficiently searched by a computer. An information object is encoded into a small "signature" or codeword. A base or "leaf" signature is computed by a known technique such as hashing. The logical intersection (AND) of each possible combination of pairs of bits of the base signature is computed, and the result is stored as one bit of a longer combinatorial signature. The bitwise logical union (bit-OR) of the combinatorial signatures of a group of records produces a second-level combinatorial signature representing particular field values present among those records. Higher-level combinatorial signatures are computed similarly. These combinatorial signatures avoid a "saturation" problem which occurs when signatures are grouped together, and a "combinatorial error" problem which falsely indicates the existence of non-existent records, thereby significantly improving the ability to reject data not relevant to a given query. When the combinatorial signatures are stored in a hierarchical data structure, such as a B- tree index of a database management system, they provide means for more efficiently searching database records or document text by eliminating large amounts of non-matching data from further consideration.
