| 20100097101 | DISTRIBUTED SUPPLY CURRENT SWITCH CIRCUITS FOR ENABLING INDIVIDUAL POWER DOMAINS - An integrated circuit includes multiple power domains. Supply current switch circuits (SCSCs) are distributed across each power domain. When a signal is present on a control node within a SCSC, the SCSC couples a local supply bus of the power domain to a global supply bus. An enable signal path extends through the SCSCs so that an enable signal can be propagated down a chain of SCSCs from control node to control node, thereby turning the SCSCs on one by one. When the domain is to be powered up, a control circuit asserts an enable signal that propagates down a first chain of SCSCs. After a programmable amount of time, the control circuit asserts a second enable signal that propagates down a second chain. By spreading the turning on of SCSCs over time, large currents that would otherwise be associated with coupling the local and global buses together are avoided. | 04-22-2010 |

| 20090248368 | Systems and methods of constructing Radial Basis Function (RBF) based meta-models used in engineering design optimization - Systems and methods of consuming radial basis function (RBF) based meta-models are described. In one aspect, a product is to be designed and optimized with a set of design variables, objectives and constraints. A number of design of experimentals (DOE) points are identified. Each of the DOE points represents a particular or unique combination of design variables. Computer-aided engineering (CAE) analysis/analyses is/are then performed for each of the DOE points. A RBF based meta-model is created to approximate the CAE analysis results at all of the DOE points. A crowding distance is calculated for each DOE point. The DOE points are sorted accordingly in a predetermined criterion such as descending order, from which a predefined number of the DOE points are chosen as RBF neuron centers. RBF parameters such as function type, width and weight factor are adjusted so that the meta-model can substantially match the CAE analysis results. | 10-01-2009 |
| 20090319453 | Sampling Strategy Using Genetic Algorithms in Engineering Design Optimization - A sampling strategy using genetic algorithms (GA) in engineering design optimization is disclosed. A product is to design and optimize with a set of design variables, objectives and constraints. A suitable number of design of experiments (DOE) samples is then identified such that each point represents a particular or unique combination of design variables. The sample selection strategy is based on genetic algorithms. Computer-aided engineering (CAE) analysis or analyses (e.g., finite element analysis, finite difference analysis, mesh-free analysis, etc.) is/are performed for each of the samples during the GA based sample selection procedure. A meta-model is created to approximate the CAE analysis results at all of the DOE samples. Once the meta-model is satisfactory (e.g., accuracy within a tolerance), an optimized “best” design can be found by using the meta-model as function evaluator for the optimization method. Finally, a CAE analysis is performed to verify the optimized “best” design. | 12-24-2009 |

| 20100325717 | System and Method for Managing Access to a Plurality of Servers in an Organization - A system for managing access to resources in a plurality of servers by a plurality of client computers by using an operating system independent Secure Shell (SSH) protocol running in each server and using a central policy database that centrally stores access rules which specify access to the servers for a plurality of users/accounts. Each time a target server receives a user request to establish an SSH session, it retrieves associated access rules from the central policy database to obtain the latest access rules. Based on the retrieved rules and the identity of the user and the identity of the client computer, the target server determines whether the user has permission to establish the SSH session with the target server. Using a centralized database and requiring the servers to always retrieve the latest access rules from a central database provides consistent application of the access rules across all servers and all client computers. | 12-23-2010 |
| 20110252459 | Multiple Server Access Management - An access management system receives an access request for a target computer from a client computer. The access request comprises a digital certificate belonging to a user. The access management system verifies the identity of the user by validating the digital certificate. When so verified, the user receives access privileges from a policy database. The access privileges contain one or more access attributes. The access management system evaluates the access request based the one or more access attributes and grants the user access to the target computer if all the one or more access attributes are satisfied. | 10-13-2011 |

| 20090204931 | Method And Apparatus For Processing Assertions In Assertion-Based Verification of A Logic Design - Method and apparatus for processing assertions in assertion-based verification of a logic design are described. One example relates to processing an assertion during verification of a logic design. An evaluation engine is generated that encodes, using a non-deterministic finite automata (NFA) model, temporal behavior of the logic design required by the assertion for a single attempt to evaluate the assertion. The evaluation engine is implemented in first reconfigurable hardware. The logic design is simulated over a plurality of clock events. Attempts to evaluate the assertion by the evaluation engine are preformed sequentially based on input stimuli obtained from the logic design during simulation thereof. Each of the attempts results in one of the assertion passing, the assertion failing, or the assertion requiring further evaluation. | 08-13-2009 |
