Patent number: 10851337Abstract: A disclosed insert for a circular-shaped petri dish can generate a substantially uniform electric field across the petri dish that is filled with a fluid establishing a salt bridge. The insert includes a circular-shaped bottom plate defining a circular-shaped space; a side channel vertically erecting from a circular periphery of said bottom plate; and a pair of current rectifying chambers each having a generally planar shape communicating with the side channel. In at least some aspects of the invention, portions of the side channel bridging the pair of current rectifying chambers each have a generally concave top profile having a lowest point at the center between the pair of current rectifying chambers such that, when the salt bridge is established, the circular-shaped space defined by the bottom plate exhibits a substantially uniform electric field in a substantially entire area of the space.Type: GrantFiled: September 16, 2016Date of Patent: December 1, 2020Assignee: OKINAWA INSTITUTE OF SCIENCE AND TECHNOLOGY SCHOOL CORPORATIONInventors: Hsieh-Fu Tsai, Amy Shen Fried, Ji-Yen Cheng

Publication number: 20130278496Abstract: An electronic display device acquires an image of a user in front of a screen of the device. The electronic display device calculates an area of the user in the image of the user and calculates an area ratio of the area of the user in the image of the user to a predefined value. The electronic display device provides a plurality of user interfaces and a plurality of ratio scopes corresponding to the plurality of user interfaces, and selects one of the plurality of user interfaces corresponding to one of the plurality of ratio scopes according to the area ratio located to display the one of the plurality of user interfaces on the screen.Type: ApplicationFiled: February 22, 2013Publication date: October 24, 2013Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: HSIEH-FU TSAI

Patent number: 8471891Abstract: A video switching system detects speaking information of at least one speaker in a video conference according to a reference time. One participant is regarded as one speaker if the one participant speaks longer than the reference time. The video switching system determines a main speaker of the at least one speaker according to the speaking information of the at least one speaker. The video switching system calculates an image switching frequency, and determines whether to switch to a video image of the main speaker according to the image switching frequency. The video switching system calculates a response time if determining to switch to the video image of the main speaker, and adjusts the reference time according to the image switching frequency and the response time.Type: GrantFiled: April 28, 2011Date of Patent: June 25, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Chih-Huang Wang, Hsieh-Fu Tsai

Patent number: 8284840Abstract: A video decoding method includes receiving video data and transforming the video data from a Huffman tree to at least one full tree and at least one one-side tree. One microcode corresponding to the video coding standard that has encoded the received video data is read where a format of the read microcode is determined. The method further includes reading video data from the transformed video data according to the consuming length of the read microcode if the format of the read microcode is a leaf, and decoding the read video data according to the decoding field of the read microcode to output a decoding result.Type: GrantFiled: December 18, 2009Date of Patent: October 9, 2012Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Hsieh-Fu Tsai, Yi-Shin Li, Yi-Shin Tung, Sheng-Che Huang, Chun Hsu

Patent number: 8243816Abstract: An entropy decoding method includes retrieving video data corresponding to an microcode, operating an entropy decoding operation on the video data to acquire a result, and retrieving video data corresponding to a subsequent microcode according to a MPS synchronously. The method further includes determining if the MPS matches the result, and operating an entropy decoding operation according to the subsequent microcode on the video data corresponding to the subsequent microcode if the MPS matches the result.Type: GrantFiled: December 16, 2009Date of Patent: August 14, 2012Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Yi-Shin Tung, Hsieh-Fu Tsai, Yi-Shin Li, Sheng-Che Huang

Publication number: 20110102212Abstract: An entropy decoding device offers all nodes on a decoding tree, and a most probable symbol for each node, and predicts presumptive information of a next node. The entropy decoding device decodes an encoded bit stream, and output a decoded content that includes real information of the next node. The entropy decoding device further generates a flush instruction to the table look-up module, when the prediction misses, and updates the most probable symbol.Type: ApplicationFiled: December 8, 2009Publication date: May 5, 2011Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: SHENG-CHE HUANG, YI-SHIN LI, HSIEH-FU TSAI
