Publication number: 20150103698Abstract: A method for producing a design topology is provided. The method includes entering a problem constraint into a computer, wherein the problem constraint includes a domain, a load vector, an objective function, and a plurality of types of materials. The domain is divided into a plurality of elements, wherein individual elements are associated with one type of material such that each of the plurality of types of materials is associated with more than one element. A element variable is calculated for the element, and the computer determines if the calculations are complete. If the calculations are not complete, the step of calculating the element variable for the elements is repeated. If the calculations are complete, the design topology is output.Type: ApplicationFiled: October 10, 2013Publication date: April 16, 2015Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: RAJAN R.

Patent number: 8046381Abstract: A communication network is described that allows legacy devices to access an IMS network. The communication network includes a switching system, an IMS network, and a non-IMS network. The switching system includes a subscriber database that is pre-provisioned with identities of IMS subscribers using legacy devices. When in operation, a calling party places a call through a legacy device. The switching system receives the call and accesses the subscriber database based on a calling party identifier (e.g., a phone number, URL, etc) to determine if the calling party is an IMS subscriber. If the calling party is an IMS subscriber, then the switching system routes the call to the IMS network. If the calling party is not an IMS subscriber, then the switching system routes the call to the non-IMS network.Type: GrantFiled: April 26, 2005Date of Patent: October 25, 2011Assignee: Alcatel LucentInventors: Yigang Cai, Simon Xu Chen, Ivy Qingfang Meng, Bill Xiang Yu Qian, Alexander Aihao Yin, Elsie Shu Fang Zhang, Eric Xiaoming Zhao

Patent number: 7605724Abstract: A digital up-sampling converter (DUSC) employs a signal input provided by a digital signal process (DSP) at a first rate feeding a Square Root Raised Cosine (SRRC) filter which provides for table look up of filter coefficients for a multiple symbol span and provides a sampling output at a second rate which is a multiple M of the first rate. A digital to analog converter (DAC) receives the sampling output at the second rate for conversion to an analog signal and a low pass analog filter processes the analog signal for delivery to an RF transmitter.Type: GrantFiled: January 11, 2006Date of Patent: October 20, 2009Assignee: Marvell World Trade Ltd.Inventors: Steve Xuefeng Jiang, Simon Xu

Patent number: 7496167Abstract: A delay buffer includes a first shift register receiving input data and having a shift signal input port. The first shift register right shifts the input data responsive to a shift signal on the shift signal input port. The shift signal is determined based on an effective bit width of the input data. A first delay line receives the shifted data from the first shift register while a second delay line of equal length to the first delay line receives the shift signal. A second shift register receives the output from the first delay line and receives the output of the second delay line on a shift signal input port. The second shift register then left shifts the data contained therein according to the shift signal.Type: GrantFiled: January 18, 2006Date of Patent: February 24, 2009Assignee: Marvell World Trade Ltd.Inventors: Cindy Chun Wang, Xiangyang Simon Xu, Xiaochun Chen

Publication number: 20080010688Abstract: IMS networks and methods are disclosed for securing media streams for IMS sessions. A CSCF of an IMS network receives a registration message, such as a SIP Register message, from user equipment (UE) of an IMS subscriber indicating whether the UE supports media security. The CSCF then forwards a registration message, such as a Diameter MAR, to a subscriber database that includes a header parameter also indicating that the UE supports media security. A media security system generates media security information (e.g., algorithms, keys, etc), and the subscriber database transmits a response message, such as a Diameter MAA, to the CSCF that includes a header parameter for the media security information. The CSCF transmits a response message, such as a SIP 200 OK message, to the UE that includes a header parameter for the media security information. The UE may use the media security information to secure media streams.Type: ApplicationFiled: November 27, 2006Publication date: January 10, 2008Inventors: Yigang Cai, Simon Xu Chen, Alex Zhi Gang Hu, Luke Zhigang Yang
