US09191397B2 Extension model for improved parsing and describing protocols
Described is a technology by which an engine parses data based upon modules arranged in a tree-like model structure. Only those modules that meet a condition with respect to the data are invoked for processing the data. Each child module specifies a parent module and specifies a condition for when the parent is to invoke the child module. As a module processes the data, if a child module's specified condition is met, it invokes the corresponding child module, (which in turn may invoke a lower child if its condition is met, and so on). When the data corresponds to protocols, the model facilitates protocol layering. A top level parent may represent one protocol (e.g., TCP), a child beneath may represent a lower-layer protocol (e.g., HTTP), whose children may handle certain types of HTTP commands, or correspond to a signature that the child module is programmed to detect.

US09191270B2 Path segment protecting p-cycles
This disclosure introduces a significant extension to the method of p-cycles for network protection. The main advance is the generalization of the p-cycle concept to protect multi-span segments of contiguous working flow, not only spans that lie on the cycle or directly straddle the p-cycle. This effectively extends the p-cycle technique to include path protection, or protection of any flow segment along a path, as well as the original span protecting use of p-cycles. It also gives an inherent means of transit flow protection against node loss. We present a capacity optimization model for the new scheme and compare it to prior p-cycle designs and other types of efficient mesh-survivable networks. Results show that path-segment-protecting p-cycles (“flow p-cycles” for short) have capacity efficiency near that of a path-restorable network without stub release. An immediate practical impact of the work is to suggest the of use flow p-cycles to protect transparent optical express flows through a regional network.

US09191125B2 Acoustic transmission
In apparatus for the acoustic transmission of power or data through a solid barrier such as a ships hull, assembly of an acoustic transducer to the hull is facilitated by bonding it first to an intermediate element by a thin layer of bonding adhesive and then bonding the intermediate element to the barrier using a second bonding layer. Acoustic matching of the transducer to the intermediate element is achieved by the thin layer, and the mechanically more robust base of the intermediate element can be rubbed on the barrier surface to displace or abrade away any unwanted debris or imperfections which might otherwise prevent the achievement of a thin second bonding layer. This makes the mounting and bonding process more tolerant of imperfections in the barrier surface due to either surface defects or particulate contamination.
