Publication number: 20240112688Abstract: The present disclosure provides an audio compression device, an audio compressing system and an audio compression method. The audio compression device comprises a first transceiver and a first processor. The first transceiver is connected to the first processor. The processor obtains an audio signal and an available bandwidth, and the processor performs an audio compression encoding on the audio signal to obtain a sample audio signal, and then compares with the audio signal and the sample audio signal to generate a residual signal, and the residual signal is transmitted according to the available bandwidth. The audio signal can be completely transmitted to an audio decompression device to reduce the distortion of the audio signal.Type: ApplicationFiled: October 4, 2022Publication date: April 4, 2024Applicant: SAVITECH CORP.Inventors: Sing-Ban Robert TIEN, Wen-Wei KANG, Wu-Lin CHANG, Chi-Feng HUANG, Lee-Chang PANG

Patent number: 8666199Abstract: An image is displayed on a touch screen. A user's underline gesture on the displayed image is detected. The area of the image touched by the underline gesture and a surrounding region approximate to the touched area are identified. Skew for text in the surrounding region is determined and compensated. A text region including the text is identified in the surrounding region and cropped from the image. The cropped image is transmitted to an optical character recognition (OCR) engine, which processes the cropped image and returns OCR'ed text. The OCR'ed text is outputted.Type: GrantFiled: July 26, 2013Date of Patent: March 4, 2014Assignee: Google Inc.Inventors: Dar-Shyang Lee, Lee-Feng Chien, Pin Ting, Aries Hsieh, Kin Wong

Patent number: 8515185Abstract: A live video stream captured by an on-device camera is displayed on a screen with an overlaid guideline. Video frames of the live video stream are analyzed for a video frame with acceptable quality. A text region is identified in the video frame approximate to the on-screen guideline and cropped from the video frame. The cropped image is transmitted to an optical character recognition (OCR) engine, which processes the cropped image and generates text in an editable symbolic form (the OCR'ed text). A confidence score is determined for the OCR'ed text and compared with a threshold value. If the confidence score exceeds the threshold value, the OCR'ed text is outputted.Type: GrantFiled: November 25, 2009Date of Patent: August 20, 2013Assignee: Google Inc.Inventors: Dar-Shyang Lee, Lee-Feng Chien, Aries Hsieh, Pin Ting, Kin Wong

Publication number: 20070037041Abstract: Titanium oxide (usually titanium dioxide) catalyst support particles are doped for electronic conductivity and formed with surface area-enhancing pores for use, for example, in electro-catalyzed electrodes on proton exchange membrane electrodes in hydrogen/oxygen fuel cells. Suitable compounds of titanium and a dopant are dispersed with pore-forming particles in a liquid medium. The compounds are deposited as a precipitate or sol on the pore-forming particles and heated to transform the deposit into crystals of dopant-containing titanium dioxide. If the heating has not decomposed the pore-forming particles, they are chemically removed from the, now pore-enhanced, the titanium dioxide particles.Type: ApplicationFiled: August 7, 2006Publication date: February 15, 2007Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Mei Cai, Yunfeng LU, Zhiwang WU, Lee Feng, Martin Ruthkosky, John Johnson, Frederick Wagner

Patent number: 7020587Abstract: The generation and management of a language model data structure include assigning each segment of a received corpus to a node in a data structure that denotes dependencies between the respective nodes. A transitional probability between each of the nodes in the data structure is calculated. A frequency of occurrence is calculated for each item of the respective segments, and those nodes of the data structure associated with items that do not meet a minimum frequency of occurrence threshold are removed. The data structure may be managed across a system memory of a computer system and an extended memory of the computer system.Type: GrantFiled: June 30, 2000Date of Patent: March 28, 2006Assignee: Microsoft CorporationInventors: Shuo Di, Kai-Fu Lee, Lee-Feng Chien, Zheng Chen, Jianfeng Gao

Publication number: 20050049144Abstract: The present invention provides a method of making a noble metal catalyst, where the noble metal is distributed on the surface of special composite carrier particles. Nanometer sized oxide particles are first dry coated by an impact mixing process on the surface of larger alumina particles. In general, this dry coating process coats the nanometer sized particles on the surface of the alumina particles. A suitable solution of noble metal(s) compound is then soaked on the surface of the composite carrier particles. Ultimately, the noble metal compound is decomposed by calcining and noble metal particles dispersed with large effective surface area on the composite carrier particles. The resultant catalyst structure improves catalyst performance while making efficient and effective use of the expensive noble metal.Type: ApplicationFiled: August 25, 2003Publication date: March 3, 2005Inventors: Mei Cai, Lee Feng, Martin Ruthkosky, Jerry Rogers
