Security incident manager
A security incident manger includes events and network flows in the analysis of an attack to better identify the magnitude of the attack and how to handle the situation. The raw events are reported by monitored devices and the incident manager may request network flows from various devices corresponding to a raw event. The manager then assigns a variable score to the severity, the relevance and the credibility of the event to determine its next processing steps. Those events that appear to be a likely and effective attack are classified as offenses. Offenses are stored in order to provide additional data for evaluating future events and for building a “rap sheet” against repeat attackers and repeat events. |

Efficient functional representation of result shaping
A result shaping methodology is part of a bridge (translation layer) between an entity provider and an underlying store provider. The bridge accepts command trees and parameter values from a consumer (e.g., the entity provider), reshapes the trees as necessary for its underlying store provider to execute, executes resulting commands, and assembles the results from the commands into the nested data reader that the initial command tree requested. The result assembly advantageously takes a mapping declaration and compiles it into a set of expression definitions composed from a small number of simple functions. Each collection in the result has a corresponding expression describing how collection elements are realized given relational results. Other expressions describe boundary detection behavior. These expressions are compiled into functions used to shape relational data into arbitrary object graphs or streaming interfaces. Alternative versions of the expressions for performance or graceful contextual error handling are also compiled. |

Incremental update scheme for hyperlink database
A database of hyperlinks, stored in a hyperlink store or distributed across multiple machines such as a scalable hyperlink store, may be incrementally updated. When data is added, instead of modifying an existing data store, a hierarchy of data stores is built. The data stores are merged together, such that a new store is a suffix on an old store. Additions and updates go into new stores, which are relatively small. Lookups consult new stores first. A background thread merges adjacent stores. For example, a batch of updates is collected and incorporated into a new store and then the store is sealed. Subsequent updates are added to yet another new store. Stores are merged occasionally to prevent the chain of stores from becoming too long. Once the batch has been integrated, the new stores are sealed and are used to answer subsequent queries. |

System and method for reducing pain in a high-voltage lead impedance check procedure using DC voltage or current in an implantable medical device
Constant voltage or current is applied to high-voltage leads to determine impedance across medical device leads. Thyristors are used for upper switching components in an H-bridge. Current is sourced into a thyristor's gate from a ground-referenced source. This current then passes from the gate to the cathode and out to the patient. By keeping the current sufficiently low, the thyristors will not conduct from the anode to the cathode. Current passes through the thyristor, lead and patient and is sensed as it returns from the other lead. The sensed current is used to regulate the injected current. Pulses of constant current on the order of tens of milliamperes can be injected and the resulting voltage can be measured. Alternatively, a constant voltage can be applied and the resulting current can be measured to determine lead impedance. |

Hierarchical common source line structure in NAND flash memory
Each memory cell string in a generic NAND flash cell block connects to a Common Source Line (CLS). A value for applying to the CSL is centrally generated and distributed to a local switch logic unit corresponding to each NAND flash cell block. For source-line page programming, the distribution line may be called a Global Common Source Line (GCSL). In an array of NAND flash cell blocks, only one NAND flash cell block is selected at a time for programming. To reduce power consumption, only the selected NAND flash cell block receives a value on the CSL that is indicative of the value on the GCSL. Additionally, the CSLs of non-selected NAND flash cell blocks may be disabled through an active connection to ground. |
