Patent number: 8116202Abstract: Methods for allocating transmission bandwidths of a network are adapted to a network including an office terminal and peripheral terminals. The peripheral terminals communicate with the office terminal by time division multiplexing during a sequence of transmitting cycles. The method includes receiving requested bandwidths from uploading messages delivered from the peripheral terminals, arranging an uploading order of the peripheral terminals based on the uploading messages to obtain a transmitting sequence, adjusting the uploading order of each of the peripheral terminals in the transmitting sequence based on a size of the requested bandwidth to obtain a modified transmitting sequence, and arranging a modified uploading order of the peripheral terminals based on the modified transmitting sequence. Therefore, the transmission bandwidth allocation is fairer, and delay is reduced. Upstream order of each terminal is transferred based on its requested bandwidth, thereby effectively reducing the average delay.Type: GrantFiled: July 7, 2009Date of Patent: February 14, 2012Assignee: Industrial Technology Research InstituteInventors: Yi-Ching Liaw, Yun-Lung Chou, Zone-Chang Lai, Yeong-Chang Maa, Chia-Chieh Tuanmu, Chu-Hsun Chang

Patent number: 7957592Abstract: A method and system of video object segmentation are disclosed herein. A pixel data of an image is received, wherein the pixel data has a corresponding location. A difference value between a pixel value of the pixel data and a pixel value in the corresponding location of a previous image is obtained. Utilizing the difference value and the pixel data, a multi-layered background registration is performed to get a background. Using the background, a background region of the image is removed. Furthermore, a process of removing an average value of luminance from the image and from the background is carried out to prevent object segmentation failure caused by the non-uniform luminance problem, which is produced by variation and flickering of illumination.Type: GrantFiled: June 22, 2007Date of Patent: June 7, 2011Assignee: Industrial Technology Research InstituteInventors: Tsung-Jen Huang, Cheng-Min Lee, Yi-Ching Liaw, Jim Zong-Chang Lai

Patent number: 7577162Abstract: Methods for allocating transmission bandwidths of a network are provided. The allocation ratio of anticipation bandwidths is adjusted according to the loading of the network to calculate the requested bandwidths, thereby effectively reducing an average delay and enhancing the utility rate of the network. Further, remaining bandwidth of the network is allocated based on maximum used bandwidth and bandwidth compensation of each terminal during the transmission cycle, to allocate excess bandwidth for each terminal. Therefore, the transmission bandwidth allocation is fairer, and delay is reduced. Upstream order of each terminal is transferred based on its requested bandwidth, thereby effectively reducing the average delay.Type: GrantFiled: March 1, 2006Date of Patent: August 18, 2009Assignee: Industrial Technology Research InstituteInventors: Yi-Ching Liaw, Yun-Lung Chou, Zone-Chang Lai, Yeong-Chang Maa, Chia-Chieh Tuanmu, Chu-Hsun Chang

Publication number: 20070013493Abstract: A multi-functional monitor utilizes a CCD camera to record the image of the head of a person. The image is then transmitted to an image processor (or a human-image recognition processor) for producing pixels of luminosity data of the image. Eventually, the pixel data are put into a central processing unit (CPU) wherein they are checked against a normal data for consistency. If they are not consistent or the person is determined to have an exceedingly high body temperature, the central processing unit (CPU) will control a driver to start a video recorder. Meanwhile, a relay will be activated to turn on a speaker and an LCD for warning the person and showing the body-temperature reading of the person. If the person continues to force in, the central processing unit (CPU) will notify a police authority through an automatic alarm system. It also warns the person with a flash light.Type: ApplicationFiled: July 18, 2005Publication date: January 18, 2007Inventor: Ching Liaw

Publication number: 20050249500Abstract: A passive optical network with a protection mechanism and its method of relocation are provided. A plurality of optical network units is defined in several optical network unit groups. Each optical network unit connects to two couplers. The two couplers connect respectively to two different optical line terminals, which are controlled by a controller. Thus, when the optical lines run out or are overloaded, the controller relocates the optical network units dynamically.Type: ApplicationFiled: December 20, 2004Publication date: November 10, 2005Inventors: Yi-Ching Liaw, Jim Lai, Yun-Lung Chou, Jia-Jay Duanmu, Yao-Yaun Chang

Patent number: 5920705Abstract: A method and apparatus for dynamically shifting between switching and routing packets efficiently to provide high packet throughput. The present invention provides a method for transmitting packets between an upstream node and a downstream node in a network that utilizes flow classification and labelling to redirect flows. The method includes the steps of establishing default virtual channels between the upstream node and the downstream node, receiving a packet at the downstream node, performing a flow classification at the downstream node on the packet to determine whether the packet belongs to a specified flow that should be redirected in the upstream node, selecting a free label at the downstream node, and informing the upstream node that future packets belonging to the specified flow should be sent with the selected free label attached.Type: GrantFiled: January 30, 1997Date of Patent: July 6, 1999Assignee: Nokia IP, Inc.Inventors: Thomas Lyon, Peter Newman, Greg Minshall, Robert Hinden, Fong Ching Liaw, Eric Hoffman, Lawrence B.
