Hohlraum used as a single turn solenoid to generate seed magnetic field for inertial confinement fusion
Application of axial seed magnetic fields in the range 20-100 T that compress to greater than 10,000 T (100 MG) under typical NIF implosion conditions may significantly relax the conditions required for ignition and propagating burn in NIF ignition targets that are degraded by hydrodynamic instabilities. Such magnetic fields can: (a) permit the recovery of ignition, or at least significant alpha particle heating, in submarginal NIF targets that would otherwise fail because of adverse hydrodynamic instability growth, (b) permit the attainment of ignition in conventional cryogenic layered solid-DT targets redesigned to operate under reduced drive conditions, (c) permit the attainment of volumetric ignition in simpler, room-temperature single-shell DT gas capsules, and (d) ameliorate adverse hohlraum plasma conditions during laser drive and capsule compression. In general, an applied magnetic field should always improve the ignition condition for any NIF ignition target design. |

Efficient event correlation in a streaming environment
In a streaming environment, efficient correlation between base events and relevant follow-on events is accomplished by temporarily storing events in an in-memory state for a limited time window. The in-memory state buffers the incoming stream of events to permit efficient attempted correlation. Successful correlation (e.g., by ID matching) between a follow-on event and a relevant base event, gives rise to specialized aggregation tables for matched (base, follow-on) event pairs. All events are ultimately removed from the in-memory state upon expiry of the time window. This results in correlated matched event pairs being stored in the aggregation tables for efficient querying. Events remaining uncorrelated upon expiration of the time window, are stored only in an (voluminous) log table for less-efficient (but rare) late querying and aggregation. Efficient correlation is achieved by assuming that successful event pair matching is most likely to occur within the in-memory time window, or not at all. |

Natural-language database interface with automated keyword mapping and join-path inferences
A natural language interface for databases (NLIDB) component of a database-management system receives a user-submitted natural-language query. The NLIDB parses the query into keywords and maps each keyword onto a corresponding query fragment that identifies a predicate of a non-join condition, or other type of expression, of a structured query. The NLIDB selects an optimal mapping for each keyword with the aid of a Query Fragment Graph (QFG) that counts the number of occurrences of each fragment, and the number of co-occurrences of each pair of fragments, in previously received structured queries. The NLIDB then uses the QFG, optionally augmented by contextual data, to select join paths most likely to be consistent with the semantic intent of the user. The NLIDB generates a structured query that incorporates the mapped query fragments and selected join paths and forwards. The structured the query is then forwarded to downstream DBMS components. |

Techniques for enabling and integrating in-memory semi-structured data and text document searches with in-memory columnar query processing
A “hybrid derived cache” stores semi-structured data or unstructured text data in an in-memory mirrored form and columns in another form, such as column-major format. The hybrid derived cache may cache scalar type columns in column-major format. The structure of the in-memory mirrored form of semi-structured data or unstructured text data enables and/or enhances access to perform path-based and/or text based query operations. A hybrid derived cache improves cache containment for executing query operations. The in-memory mirrored form is used to compute queries in a transactionally consistent manner through the use of an invalid vector that used to determine when to retrieve the transactionally consistent persistent form of semi-structured data or unstructured text data in lieu of the in-memory form. |

Process and framework for facilitating information sharing using a distributed hypergraph
A knowledge model “overlay” for organizing and analyzing large, dynamic data volumes is implemented as a hypergraph that manifests as a result of a distributed theory-driven data source transformation process. This process maps exponentially growing data into an asymptotically limited information space. Within this space, real-world entities (e.g. people, computers, cities, Earth) and their complex interdependencies (e.g. social networks, connectivity, causal relationships) are represented as attributed hypergraph elements (i.e. both hypervertices and hyperedges). Attributes are represented as state vectors affixed to any hypergraph element. Transformation of source system data into this overlay structure is accomplished with minimal data movement and replication using a universal “pointer” like mechanism that is managed in a decentralized fashion by the respective transformation components. Access to the knowledge overlay is performed via a hypergraph communication protocol encapsulated within a common hypergraph API and accompanying hypergraph toolkit. |

Multi-depth liquid crystal electrode layer lens
A typical liquid crystal lens includes liquid crystal sandwiched between transparent substrates, which are patterned with ring electrodes. Applying a voltage across the electrodes causes the liquid crystal molecules to rotate, changing their apparent refractive index and the lens's focal length.

To address this problem, an inventive liquid crystal lens includes a substrate with a stepped surface that defines concentric liquid crystal regions with thicknesses that increase with lens radius. Each region is switched by a different set of ring electrodes, which may be on, under, or opposite the stepped surface. Within each region, the ring electrodes get narrower farther from the lens's center. But the ring electrodes' widths also increase with liquid crystal thickness, offsetting the decrease in width that degrades lens performance. |

Force sensor
A force sensor includes a frame and an oscillation structure which has arms and can oscillate freely in the frame. The arms are fixed to suspension frame regions and run transverse to one another at least in sections. At least one conductor extends along at least two arms. An AC voltage can be applied to the at least one conductor to excite at least one oscillation mode of the oscillation structure with a resonant frequency using Lorentz force. The force sensor is designed such that the suspension regions are at least partially spatially displaced relative to one another when a force is applied to the frame, that the magnitude of the spatial displacement of the suspension regions depends on the magnitude of the force, and that the spatial displacement of the suspension regions causes detuning of the resonant frequency, the magnitude of which depends on the spatial displacement magnitude. |

Image sensor incorporating an array of optically switchable magnetic tunnel junctions
An image sensor includes an array of optically switchable magnetic tunnel junctions (MTJs) arranged in columns and rows. The image sensor has first lines of transparent conductive material and second lines of conductive material. Each first line is in contact with the free layers of the MTJs in a corresponding row. Each second line is electrically connected to the fixed layers MTJs in a corresponding column. The first lines are concurrently exposable to radiation. The first and second lines are selectively biasable. In a global reset operation, biasing conditions are such that all MTJs are switched to an anti-parallel state. In a global sense operation, biasing conditions are such that, depending upon the intensity of radiation received at those portions of the first lines in contact with MTJs, the MTJs may switch to a parallel state. In selective read operations, biasing conditions are such that stored data values in the MTJs can be read. |

Vibration sensor mounting structure
A vibration sensor mounting structure improves the stability and repeatability of a measured signal generated by a machine vibration sensor. The structure has an outer annular surface that contacts the machine under test and a shallow recess inside the outer annular surface. The recess causes resonant vibrations of the mounting structure to occur at frequencies that are above the intended measurement range of the sensor. The recess also allows the mounting force to be positioned away from the center mounting screw and onto the more stable outer annular surface. With the mounting force away from the center, lateral forces have less effect on the measured signal. |
