Patent number: 8331934Abstract: Various embodiments are described to assist in reducing handoff delays and the blackout period(s) associated with inter AN (access network) hard handoffs. The hard handoff procedure of method disclosed herein establishes or initiates a connection (A10-type connection) between a target AN and a packet data serving node (PDSN), unlike known hard handoff approaches that wait until traffic channel assignment to establish or initiate such connection. The PDSN may optionally bicast data packets to both the source and target ANs since each is communicatively coupled to the PDSN during a given time period. In the event bicasting is unavailable or unused, a communication tunnel between the source and target ANs may be created and used to transmit data packets between them.Type: GrantFiled: June 9, 2006Date of Patent: December 11, 2012Assignee: Microsoft CorporationInventors: Mohamed Khalil, Haseeb Akhtar

Patent number: 8293544Abstract: A method (and semiconductor device) of fabricating a semiconductor device utilizes a thermal proximity correction (TPC) technique to reduce the impact of thermal variations during anneal. Prior to actual fabrication, a location of interest (e.g., a transistor) within an integrated circuit design is determined and an effective thermal area around the location is defined. Thermal properties of structures intended to be fabricated within this area are used to calculate an estimated temperature that would be achieved at the location of interest from a given anneal process. If the estimated temperature is below or above a predetermined target temperature (or range), TPC is performed. Various TPC techniques may be performed, such as the addition of dummy cells and/or changing dimensions of the structure to be fabricated at the location of interest (resulting in an modified thermally corrected design, to suppress local variations in device performance caused by thermal variations during anneal.Type: GrantFiled: July 28, 2008Date of Patent: October 23, 2012Assignee: GlobalFoundries Singapore Pte. Ltd.Inventors: Debora Chyiu Hyia Poon, Alex Kh See, Francis Benistant, Benjamin Colombeau, Yun Ling Tan, Mei Sheng Zhou, Liang Choo Hsia

Patent number: 8258748Abstract: A computer-based processing system (e.g., host server) is operable for receiving historical device operation information (power consumption data) collected during operation of the remote battery-operated device in accordance with a first set of operating parameters. The first set of operating parameters enable operation of the battery-operated device in a first operating mode. The processing system calculates an observed battery life for the device based on the received historical power consumption data and a power capacity value representing a power capacity of the battery resident in the device. This observed battery life may be output to a user and used to determine whether the device will meet a predetermined operational life. If not, parameters for the device can be modified and a new projected battery life calculated (simulation), with the new modified parameters controlling power consumption in the device.Type: GrantFiled: March 11, 2009Date of Patent: September 4, 2012Assignee: Enfora, Inc.Inventors: Scott Douglas Constien, Charles Chapman Moore, Daniel Martin Donahue, Thomas Howard Daugherty, Jr.

Patent number: 8130645Abstract: A switch architecture and method provides scaling through multi-level load balancing of flows across data and application processing planes. An input/output module receives a communication session flow (forward) from a client device and selects one of a plurality of data processors to process the flow. The selected data processor determines the level of processing needed for the forward flow and selects an application processor from a plurality of such application processors. The application processor generates a session structure identifying actions to be performed on the forward flow and transfers the session structure to the selected data processor to perform the actions on the forward flow. The application processor also predictively generates and offloads a session structure for the associated reverse flow. If the reverse session structure is offloaded to a different data processor, either the forward or reverse flow redirects packets, or is redirected, to the data processor hosting the other flow.Type: GrantFiled: January 11, 2010Date of Patent: March 6, 2012Assignee: Nortel Networks LimitedInventors: Kumara Das Karunakaran, M.

Patent number: 8114769Abstract: A method for semiconductor fabrication using a trench first metal hard mask (TFMHM) process for damascene structures includes forming a secondary metal hard mask layer above a first metal hard mask layer after trench opening for the via (and trench) etching. The secondary metal hard mask layer is formed of metal material substantially resistant to the etching process which enables via etching to self-align (using an edge of the secondary metal mask layer). In one embodiment, the secondary metal mask layer is formed using an electroless deposition process, and may include nickel (Ni), cobalt (Co), gold, (Au), palladium (Pd), cadmium (Cd) silver (Ag), ruthenium (Ru), and alloys and/or combinations thereof. Because the first metal hard mask is usually formed of TiN, the trench and via etching process removes a significant amount of the TiN layer. Utilization of the secondary metal hard mask to protect the first metal hard mask layer further enables a reduction in the thickness of the first metal hard mask layer.Type: GrantFiled: December 31, 2010Date of Patent: February 14, 2012Assignee: Globalfoundries Singapore Pte, Lte.Inventors: Ravi Prakash Srivastava, Elbert Huang

Patent number: 7911283Abstract: A low noise oscillator includes a resonator 102 that is excited with a pulsed signal (i.e., an impulse of energy) to replace energy lost to parasitic resistive losses once every Nth period (where N=1, 2, 3 . . . ). The resonating signal is monitored by a level detector and when the signal falls below a predetermined threshold, the pulse generator outputs a pulse or adjusts pulse width, pulse amplitude (or both) of a pulsed signal to create the necessary impulse for application to the resonator to recoup losses resulting from resonator operation. A phase shifting circuit may be provided to ensure the pulses are time aligned with the resonating signal to reduce noise.Type: GrantFiled: December 31, 2007Date of Patent: March 22, 2011Assignee: Nortel Networks LimitedInventors: Adrian J.
