43.72.-p MULTIPLE SCORE LANGUAGE PROCESSING SYSTEM

Keh-Yih Suet al., Hsinchu, Taiwan 23 May 1995 (Class 364/419.08); filed 27 August 1990

The patent discloses a method of speeding up the process of parsing a natural-language sentence. The technique involves a scoring method to trun- cate unlikely branches from the search space. Based on a training step using examples of text on similar topics, a parse scoring system is built up, which may include lexical, syntactic, and semantic information. This information helps to make decisions when ambiguities arise in the parsing process.-- DLR

Arthur Jampolsky, assignor to Jay Management Trust 18 July 1995 (Class 381/68.4); filed 6 March 1991

The patent, in its primary form, shows two BTE hearing aids and a control box that permits adjustment of the relative phase and amplitude between the two heating aids. Establishing the correct relationship between these factors is stated to give significantly improved heating results.--SFL

Chan S. Lim and Gregg A. Salsi, assignors to International Business Machines Corporation

23 May 1995 (Class 364/419.16); filed 7 June 1993

Word processors and other text handling systems for languages such as Japanese and Chinese, with non-letter-based writing systems, have widely adopted a double-byte character set for text storage. However, according to the present patent, this is the first implementation of the ability to mix both single- and double-byte sets with the same program. Each sentence has an

Hiroshi Suematsu, assignor to NEC Corporation 23 May 1995 (Class 364/419.01); filed 26 July 1990

This natural language parser efficiently builds a search pattern table and performs the search in a way which provides both syntactic and seman- tic information describing the parsed sentence. A dictionary word lookup, with some morpheme processing, returns possible parts of speech and lists

of candidate syntactic patterns. Local rules eliminate most of the part-of- speech ambiguities. A sentence pattern search table is then built using lan- guage characteristics (e.g., predicate position in English, marker particles in Japanese) and transformation effects. A "predicate slot" numbering arrange- ment allows efficient searching of the sentence pattern table. The patent is well written and includes a glossary and bibliography.--DLR

43.72.Gy ACOUSTIC SIGNAL TRANSMITTING SYSTEM

Yutaka Ogawa, assignor to Fuji Xerox Company 6 June 1995 (Class 455/70); filed in Japan 30 September 1991

The patent describes an audio signal transmission system which mul- tiplexes one of multiple microphone signals into a single audio channel, along with a flag indicating which microphone is currently active. This could be used, for example, in a remote conferencing system in which the

current speaker's name could be displayed automatically at the receiver. The patent is strictly conceptual in nature and discloses no technical implemen- tation details. The discriminating devices are referred to merely as "filters."--DLR

SYMBOLS, FINGERS AND SENSOR AREAS

Leroy D. Young, Jr., assignor to Conchord Expert Technologies, Incorporated

20 June 1995 (Class 84/483.2); filed 19 February 1993

This patent discloses a new electronic musical instrument for which the performance instructions use a new notational method, all in the interest of allowing the user to play the instrument quickly at an advanced level of performance. The instrument "is pi'ayed using the right hand for depression of keys, as in conventional instruments, and also by applying finger pressure onto special sensing areas using the left hand. The left hand sensing areas or keys are located so as to be accessed without any significant lateral move- ment of the left hand. 'Instructions' for playing the new instrument are conveyed to the user via directly translatable notational symbols printed on an associated surface."--DWM

43.75.Bc KEYBOARD INSTRUMENT FOR THE NATURAL TONE SYSTEM

Johannes Kotschy, Piding, Germany 11 July 1995 (Class 84/423 R); filed in Germany 10 September

1991

The basic claim of this patent narrowly defines "natural tones" but describes a three-level keyboard having 16 keys per octave on which such tones can be played. Claim 1. "A keyboard instrument for the natural tone system in which natural tones of a frequency f(n,m) are structured on a given fundamental of a frequency f(0) as follows: f(n,m)=f(O)Xn x m (n,m = 1,2,3 .... 64 .... ), whereby n represents the natural tone number and m represents a modulation factor, comprising at least one keyboard

having keys that are assigned to the natural tones in a predetermined se- quence characterized by the fact that sixteen keys are provided per octave, and that the keys are arranged and constructed in such a way that natural tones 4 to 7 (24), are assigned to a first contiguous sequence of keys at a first playing level, natural tones 8 to 15 (25, 34) are assigned to a second con- tiguous sequence of keys at second playing level, and natural tones 16 to 31 (26, 35, 44, 45) are assigned to a third contiguous sequence of keys at a third playing level."--DWM
