| 20090009166 | METHOD OF USING G-MATRIX FOURIER TRANSFORMATION NUCLEAR MAGNETIC RESONANCE (GFT NMR) SPECTROSCOPY FOR RAPID CHEMICAL SHIFT ASSIGNMENT AND SECONDARY STRUCTURE DETERMINATION OF PROTEINS - The present invention presents a new approach to rapidly obtaining precise high-dimensional NMR spectral information, named “GFT NMR spectroscopy”, which is based on the phase sensitive joint sampling of the indirect dimensions spanning a subspace of a conventional NMR experiment. The phase-sensitive joint sampling of several indirect dimensions of a high-dimensional NMR experiment leads to largely reduced minimum measurement times when compared to FT NMR. This allows one to avoid the “sampling limited” data collection regime. Concomitantly, the analysis of the resulting chemical shift multiplets, which are edited by the G-matrix transformation, yields increased precision for the measurement of the chemical shifts. Additionally, methods of conducting specific GFT NMR experiments as well as methods of conducting a combination of GFT NMR experiments for rapidly obtaining precise chemical shift assignment and determining the structure of proteins or other molecules are disclosed. | 01-08-2009 |

| 20100290348 | GENERATION AND USAGE OF MOBILITY VLAN ID VERSION VALUE - A mobility network architecture includes a control plane and data plane. The control plane supports notification of VLAN configurations. The data plane supports routing of data amongst VLANs. Each VLAN has an associated identifier value as well as a version number. The version number for a respective VLAN can be updated to a new value each time there is a change to the VLAN. Typically, a controller communicates over the control plane to notify each member switch when a version number has changed for a VLAN. If controller notification fails, a member switch can receive a notification from a neighboring switch that the version number for a VLAN has been modified. In response to detecting such a condition, the switch receiving the notification can prevent forwarding of data even though the switch does not receive notification from the controller that the version number for the VLAN has changed. | 11-18-2010 |

| 20100290385 | PREVENTING PACKET LOOPS IN UNIFIED NETWORKS - Unified mobility switches often define a virtual LAN (VLAN), including a combination of mobility tunnels and access tunnels, via which packets are transported to a mobile device over a combination of physical connections and wireless links. A unified switch may have multiple ports available to route a packet to a particular destination, since the unified switches identify routing paths for both physical connections and VLANs. A particular unified switch may therefore have multiple routes to a common destination, which can lead to a routing loop across a network of switches supporting both physical and virtual connections. A unified mobility switch provides loop detection and prevention through a set of rules for qualifying connections as virtual tunnels or physical connections, and defining a single path where multiple potential paths exist. | 11-18-2010 |
| 20100290446 | METHOD FOR ENABLING MOBILITY OF CLIENT DEVICES IN LARGE SCALE UNIFIED NETWORKS - Embodiments herein include systems and methods for providing a mechanism to enable smooth, seamless, and reliable connectivity for wireless devices in a unified network. The system supports roaming of mobile units across mobility switches. A given mobile unit can retain its IP address in both intra-subnet and inter-subnet roaming scenarios. The given mobile unit also retains its membership to a mobility VLAN to which it had been assigned, even during roaming scenarios. Embodiments include a framework for wireless switches to advertise VLANs they support to peer wireless switches in the mobility domain, and to advertise their capability to act as VLAN servers for those VLANs. Embodiments support VLAN membership management capabilities that allow access points and peer wireless switches to request wireless switches to add VLANs to the tunnels they share. | 11-18-2010 |
| 20100293272 | TOLERANT DEVICE LICENSING IN A DISTRIBUTED ENVIRONMENT - Methods, apparatus and a computer program product provide for a Tolerant License Manager that defines a cluster of a plurality of network controllers, wherein each respective network controller contributes at least one license to a current total amount of licenses in a license pool. The Tolerant License Manager identifies at least one threatened access point upon detecting a first network controller has become unavailable. Each threatened access point comprises any access point connected to the first network controller when the first network controller becomes unavailable. The Tolerant License Manager establishes (and/or) approves a connection between a back-up controller and the threatened access point(s). While the first network controller is unavailable, the Tolerant License Manager allocates a license to each threatened access point via the back-up network controller. | 11-18-2010 |
