Patent number: 7536212Abstract: In a short range radio communication headset, signals transmitted by the short range radio communications are received while direct sounds propagated from an external are detected. Then, a digital signal adaptation processing using either received signals or the direct sounds as reference signals are applied, and a ratio between the received signals and the direct sounds is controlled by correlating the reference signals and another one of the received signals and the direct sounds that are not used as the reference signals and extracting necessary components.Type: GrantFiled: September 18, 2006Date of Patent: May 19, 2009Assignee: Kabushiki Kaisha ToshibaInventors: Katsuyoshi Nagayasu, Shinichi Tanaka, Kohei Momosaki, Yoichi Takebayashi

Patent number: 6178399Abstract: Time series signals are recognized by extracting a multiplicity of candidate feature vectors characterizing an individual time series signal without fixing a boundary for the individual time series signal, and calculating similarity values for each of the multiplicity of candidate feature vectors and the reference patterns stored in the recognition dictionary, from which one reference pattern for which the similarity value is greater than a prescribed threshold value is selected as a recognition result. New reference patterns to be stored in the recognition dictionary are learned by artificially synthesizing signal patterns with variations for learning; extracting feature vectors for learning from the recognition results and the similarity values obtained by the recognizing step from the signal patterns with variations for learning; and obtaining new reference patterns from the feature vectors for learning extracted by the extracting step.Type: GrantFiled: April 24, 1995Date of Patent: January 23, 2001Assignee: Kabushiki Kaisha ToshibaInventors: Yoichi Takebayashi, Hiroshi Kanazawa, Hiroyuki Chimoto

Patent number: 6098061Abstract: A computer-understandable knowledge base for accumulating computer-understandable task knowledge and a know-how knowledge base for accumulating know-how knowledge understandable for a human being are provided. In accordance with, for example, a result of the process for solving a problem which has been performed by the computer-understandable knowledge base 1, know-how knowledge relating to the problem solution is automatically retrieved and presented. Since know-how knowledge relating to the problem solution is automatically retrieved and presented in accordance with the state of the problem solving process which has been performed by the computer-understandable knowledge base, a user is able to efficiently make a reference to required know-how knowledge without a complicated process for conditions for retrieving the know-how knowledge. Even if a problem cannot be solved by the computer-understandable knowledge base, the know-how knowledge is used to guide the problem solution.Type: GrantFiled: March 13, 1997Date of Patent: August 1, 2000Assignee: Kabushiki Kaisha ToshibaInventors: Kazuyuki Gotoh, Hideo Numagami, Yoichi Takebayashi, Kouichi Sasaki

Patent number: 5918222Abstract: A data storage means stores data in a predetermined information form. An information retrieval means retrieves the data stored in the data storage means. A reception means receives an information disclosure demand from a demander, a response rule storage means for storing general knowledge for generating a response responding to the demander and a personal relationship information associated with a unique personal relationship between a user having the data on an information provider side and a user on an information demander side. A response plan formation means, responsive to the demand received by the reception means, plans a response for exhibiting, to the information demander, data obtained by causing the retrieval means to retrieve the data stored in the data storage means on the basis of the knowledge and the personal relationship information stored in the response rule storage means.Type: GrantFiled: March 15, 1996Date of Patent: June 29, 1999Assignee: Kabushiki Kaisha ToshibaInventors: Mika Fukui, Kouichi Sasaki, Kazuyuki Gotoh, Yasuyo Shibazaki, Akira Morishita, Yoichi Takebayashi, Yoshihisa Ohtake

Patent number: 5907841Abstract: A document detection system capable of detecting a desired document from a large number of documents easily and accurately in which the user can make a judgement concerning the appropriateness of the detection result quickly. In the system, those documents which contain a semantic structure of a detection command containing natural language expressions entered by a user are detected. Also, the keywords of each document can be extracted from the summary of each document and those documents whose keywords match with detection keywords specified by a user can be detected. Also, the summary of each detected document can be automatically generated according to text structures of each detected document and displayed along with the detected document itself. Also, the detection processing can be carried out with respect to the summaries of the documents instead of the documents themselves.Type: GrantFiled: August 1, 1996Date of Patent: May 25, 1999Assignee: Kabushiki Kaisha ToshibaInventors: Kazuo Sumita, Seiji Miike, Kenji Ono, Yoichi Takebayashi, Kimihito Takeda, Etsuo Ito

Patent number: 5794194Abstract: Low- and high-dimensional feature parameters are obtained by analyzing a speech pattern to be recognized. A word spotting section extracts a plurality of approximate word feature vector candidates representing word features from the low-dimensional feature parameter without fixing word boundaries. Start and end points are detected for each of the word feature vector candidates. Detail word feature vector candidates are extracted from the high-dimensional feature parameter in accordance with the detected start and end points. A recognition dictionary stores reference patterns with which the detail word feature vector candidates are matched. A pattern matching section calculates similarity values between each of the detail word feature vector candidates and the reference patterns stored in the recognition dictionary. A recognition result selects reference patterns stored in the recognition dictionary when its similarity value is greater than a prescribed threshold value.Type: GrantFiled: February 3, 1997Date of Patent: August 11, 1998Assignee: Kabushiki Kaisha ToshibaInventors: Yoichi Takebayashi, Hiroyuki Tsuboi, Hiroshi Kanazawa

Patent number: 5787414Abstract: A data retrieval system capable of carrying out the retrieval using the secondary information of the primary data to be retrieved such as environmental information or structural information as the retrieval key. In the system, the primary data which are filing target to be stored and retrieved are stored in a first memory while secondary information associated with the primary data, which are not directly related with data content of the primary data, are stored in a second memory in correspondence to the primary data stored in the first memory. Then, when a retrieval key specifying a desired retrieval of the primary data from the first memory is entered, the secondary information is selected from the second memory in accordance with the retrieval key, and the primary data corresponding to the secondary information selected in accordance with the retrieval key is retrieved and outputted as a retrieval result.Type: GrantFiled: September 26, 1996Date of Patent: July 28, 1998Assignee: Kabushiki Kaisha ToshibaInventors: Seiji Miike, Satoshi Ito, Hiroshi Mizoguchi, Yoichi Takebayashi, Mika Fukui, Yoshiaki Kurosawa, Akira Morishita, Shigenobu Seto, Hideaki Shinchi, Yasushi Kawakura, Yoshikuni Matsumura, Hisako Tanaka
