Patent number: 9358055Abstract: Techniques are generally described related to a method and system for treating an injury with a bone screw. One example bone screw may be configured to fracture at a pre-selected frangible location so that the point of failure is not in an inaccessible location, e.g., deeply embedded below the surface of a treated bone. The bone screw may further include a material disposed over the frangible location that is designed to temporarily strengthen the screw and selected to be absorbed by the body over a period of time after installation of the screw in the bone. One example bone screw may include an unthreaded portion that is configured to facilitate removal of an embedded screw fragment from a bone in the event that the screw fails in vivo.Type: GrantFiled: May 27, 2014Date of Patent: June 7, 2016Assignee: TONGJI UNIVERSITYInventors: Liming Cheng, Yan Yu, Zhili Zeng, Wei Xu, Yongwei Jia, Lie Qian, Rui Zhu, Jianjie Wang, Zhourui Wu

Patent number: 8992577Abstract: A rod system includes two rods each with a head and a shaft, two elastic members each fitted around one shaft against one head, and a case defining a first inner portion, a second inner portion, and a third inner portion in communication with the first and the second inner portions. A first rod with a first elastic member is seated in the first inner portion so the first elastic member abuts the bottom of first inner portion and the first head protrudes into the third inner portion. A second rod and a second elastic member is seated in the second portion so the second elastic member abuts the bottom of the second inner portion and the second head protrudes into the third inner portion and abuts the first head.Type: GrantFiled: March 13, 2014Date of Patent: March 31, 2015Assignee: Tongji UniversityInventors: Liming Cheng, Yan Yu, Zhili Zeng, Wei Xu, Yongwei Jia, Lie Qian, Rui Zhu, Jianjie Wang, Zhourui Wu

Patent number: 7570649Abstract: The sharing of forwarding states between multiple traffic paths is described. There is described a method for establishing a data traffic path in a communication network from a first node towards a second node. The method includes searching a set of pre-existing forwarding states for a pre-existing forwarding state associated with the first node for defining the traffic path from the first node towards the second node. If the pre-existing forwarding state for defining the traffic path cannot be found in the set of pre-existing forwarding states, then a new forwarding state for defining the traffic path from the first node towards the second node is generated the new forwarding state is used to establish the traffic path from the first node towards the second node. An apparatus implementing the method is described. The sharing of forwarding states as described may be used in MPLS enabled networks.Type: GrantFiled: February 28, 2005Date of Patent: August 4, 2009Assignee: Alcatel LucentInventors: Lie Qian, Yiyan Tang, Yuke Wang, Bashar Bou-Dlab, Wladyslaw Olesinski

Publication number: 20060182027Abstract: The invention relates to a method for controlling data traffic in a telecommunications network (150), said control being carried out in terms of a statistic modeling of the traffic transmitted by the network (150) by means of a gaussian distribution of the data flow. According to the invention, one such method is characterized in that a characteristic value of the Gaussian distribution is weighted by means of a parameter ? which varies according to the intensity of the variations or the discontinuity, of the traffic process by said network (150), said weighted value being used to evaluate the traffic in the network.Type: ApplicationFiled: June 28, 2004Publication date: August 17, 2006Applicant: ALCATELInventors: Alberto Conte, Philippe Dauchy, Lie Qian, Yuke Wang, Yiyan Tang, Anand Krishnamurthy

Publication number: 20050050060Abstract: A disjoint graph structure for packet classification in communication systems is presented. The disjoint graph is comprised of two types of data structures; an elementary interval tree (EIT) and a disjoint interval tree (DIT). The disjoint graph is constructed based on a range-specified rule set finding particular application in the classification of data packets. Each rule in the rule set has an equal number of fields and each field specifies a range referred to as an integer interval having a lower and an upper bound. The disjoint graph has the same number of layers as there are fields in each rule. The layers are comprised of nodes, and each node has an associated rule set selected from the range-specified rule set. The disjoint graph enables packet classification in only one pass through the tree. The EIT and DIT structures are also presented in detail.Type: ApplicationFiled: August 27, 2003Publication date: March 3, 2005Inventors: Gerard Damm, Bashar Bou-Diab, Yuke Wang, Yun Zhang, Yiyan Tang, Anand Krishnamurthy, Lie Qian
