Patent number: 8185797Abstract: The invention relates to a base matrix, a encoder/decoder of Low Density Parity Check (LDPC) codes and a generation method thereof. The encoder/decoder is determined uniquely by the parity check matrix of the LDPC codes. With different code sizes, said parity check matrix can be obtained by expanding different base matrixes, and also can be obtained by expanding a unique base matrix after correction. Elements of said base matrix must meet an inequation in which the girth value is up to the standard, e.g. when girth?6, for any element i, j, k, l in the matrix which forms the short loop having a length of 4 in anticlockwise, there are always mod(i?j+k?l, z) unequal to 0.Type: GrantFiled: April 25, 2005Date of Patent: May 22, 2012Assignee: ZTE CorporationInventors: Xu Jun, Yougang Zhang, Liuqing Yuan

Publication number: 20090294114Abstract: A heat dissipation device includes a heat pipe and a heat sink. The heat pipe includes an evaporator section and a rectangular condenser section extending from one end of the evaporator section and surrounding the evaporator section. The heat sink includes a main body and a plurality of fins extending outwardly from four lateral sides of the main body. The main body defines a groove on an end surface thereof for receiving the evaporator section therein. Each of the fins includes a plate-shaped body and a flange extending perpendicularly from an end of the plate-shaped body. The top flanges cooperatively form a rectangular supporting surface for supporting the condenser section thereon. The supporting surface is lower than the end surface of the main body.Type: ApplicationFiled: April 27, 2009Publication date: December 3, 2009Applicants: FU ZHUN PRECISION INDUSTRY (SHEN ZHEN) CO., LTD., FOXCONN TECHNOLOGY CO., LTD.Inventors: Ming Yang, Xu-Jun Zhong, Shou-Li Zhu, Qing-Lei Guo

Publication number: 20070002013Abstract: An input device encodes motion using a laser self-mixing velocimeter. The laser beam is directed at a disk or other moving member. As light from that beam is reflected back into the emitting cavity of the laser, the beam power output fluctuates because of the self-mixing effect and generates a beat signal. The beat signal frequency is used to determine the speed of the member's motion. The direction of motion is also determined based on the beat signal. A difference frequency analog phase locked loop filters the beat signal. A zero-point control disables motion detection when the average beat signal amplitude falls below a threshold. A triangle modulator generates a triangle wave for the laser bias current, with the triangle wave frequency being a submultiple of the beat signal frequency.Type: ApplicationFiled: June 30, 2005Publication date: January 4, 2007Applicant: Microsoft CorporationInventors: Yuan Kong, Craig Ranta, Zhao Tianpeng, Ming Hai, Xie Jianping, Xu Jun, He Deyong

Patent number: 6081806Abstract: In a computer database synchronization method, a first database with first object data and a second database with second object data are established in a personal computer and an electronic dictionary, respectively. First and second synchronization status tables are established for each of the first and second object data, respectively. The synchronization status tables are modified from a first state, indicating that the corresponding object data is synchronized with the first or second database, to a second state, indicating that the corresponding object data is not synchronized with the first or second database, when the corresponding object data is edited. Synchronizing of the first and second databases can begin when a communications link is established between the personal computer and the electronic dictionary.Type: GrantFiled: January 15, 1998Date of Patent: June 27, 2000Assignee: Inventec CorporationInventors: Ching-Sung Chang, Shih-Kuang Tsai, Dai-Shui Ho, Xu-Jun Qiu
