Publication number: 20140019128Abstract: Described herein are systems and methods for transforming a speech input into machine-interpretable structured data. In some embodiments, a system may include an automated speech recognition (ASR) engine configured to receive a live speech input and to continuously generate a text of the live speech input, a natural language processing (NLP) engine configured to transform the text into machine-interpretable structured data, and a user interface device configured to display the live speech input and a corresponding portion of the structured data in a predetermined order with respect to the structured data. In some embodiments, the method may include the steps of receiving a speech input with a speech capture component of a user interface device, generating a text from the speech input, identifying textual cues in the text, modifying the text based on the textual cues, and transforming the modified text into machine-interpretable structured data.Type: ApplicationFiled: June 27, 2013Publication date: January 16, 2014Inventors: Daniel J. Riskin, Anand Shroff, Yan Chow, Brian A. Dummett, Ritu Raj Tiwari

Patent number: 8329425Abstract: Fast and simple method of detecting the presence of chloramphenicol, a harmful compound if present in food products. The method makes use of a mutant chloramphenicol acetyltransferase (CAT) and a fluorophore-linked chloramphenicol in a system where chloramphenicol and the fluorophore-linked chloramphenicol competes for the active site of the mutant CAT. Because the fluorophore-linked chloramphenicol reduces its fluorescence upon binding to the active site and vice versa increases its fluorescence upon being displaced from the active site by the presence of unmodified chloramphenicol in a sample, the increase of fluorescence caused by a testing sample indicates the presence of chloramphenicol.Type: GrantFiled: February 28, 2011Date of Patent: December 11, 2012Assignee: The Hong Kong Polytechnic UniversityInventors: Kwok-Yin Wong, Yun Chung Leung, Pak Ho Chan, Wai Hong Chung, Ka Yan Chow, Ho yin Chow, Hon Man Leung

Patent number: 6111019Abstract: This invention is for LLDPE blends with an ethylene-norbornene copolymer for resins and improved toughness and processibility for film production. This invention provides LLDPE based resins which are significantly improved with respect to their capability to be fabricated into a film layer, particularly by a blown bubble extrusion technique. Films prepared of the LLDPE/E-NB melt blended resins of this invention are significantly improved with respect to certain of their film properties, such as tear strength, without detracting from the beneficial properties that a LLDPE otherwise provides to a film.Type: GrantFiled: March 31, 1997Date of Patent: August 29, 2000Assignee: Exxon Chemical Patents, Inc.Inventors: Palanisamy Arjunan, Wai Yan Chow, Bruce Allan Harrington, Yu Feng Wang, Henry Yang
