Abstract: Methods, systems, and media for presenting search results are provided. In accordance with some embodiments, the method comprises: receiving text corresponding to a search query; determining whether a content rating score associated with the search query is below a predetermined threshold, wherein the score is calculated by: identifying a first plurality of search results retrieved using the search query, wherein each search result is associated with one of a plurality of content ratings classes; and calculating the content rating score that is a proportion of search results associated with at least one of the content ratings classes among the first plurality of search results; in response to determining that the content rating score is below the predetermined threshold, identifying a second plurality of search results to be presented based on the search query; and causing the second plurality of search results to be presented.

Abstract: The invention relates to a trough collector comprising a number of secondary concentrators, by which the solar radiation concentrated by the concentrator of the trough collector in a first direction transverse to the length thereof is concentrated in a second direction running along the trough collector, wherein the secondary concentrators each have a first, front reflecting wall and a second, rear reflecting wall which concentrate the radiation in the second direction, and wherein the secondary concentrators are arranged such as to be synchronously pivotable with one another, preferably about a respective pivot axis fixed with respect to the primary concentrator, such that as the position of the sun changes, the secondary concentrators can always be oriented in accordance with the incident radiation.

Abstract: Compensation circuitry includes a resistor and transistor coupled in series with a reference current source to generate a variable reference voltage that is provided, via a voltage regulator, to bias elements of a core circuit in order to establish an operating current in the core circuit. In one embodiment, the resistor and transistor of the compensation circuitry are of similar construction to the bias elements of the core circuit, such that fluctuations in the ratio of the reference current and the operating current of the core circuit are minimized over process, supply voltage and temperature variations. The voltage regulator may be a low dropout regulator. In various embodiments, the core circuit may comprise a resistor biased voltage controlled oscillator, a differential current mode logic (CML) input to single CMOS output circuit, or like circuitry that may be sensitive to phase noise or requires low power operation.

Abstract: A system and method are used to accelerate settling or steady state of an amplifier in an amplifier system. This is used to ensure the amplifier reaches steady-state within a specified time period from stand-by or another state without using more current than is needed for steady-state. A comparator in a common-mode feedback system compares a desired amplifier output signal to one or more nodes of the amplifier. A result of the comparison is compared to a threshold value using a comparator in a settling acceleration system. If the result crosses the threshold, a controller turns on a driver in the settling acceleration system. The driver pulls on one or more nodes of the amplifier, which, along with a driver in the amplifier system pulling on the node, quickly brings the amplifier to settling or steady state.

Abstract: The invention relates to a system and method for the enrichment and curation of concept, relationship, and assertion information into a multi-relational ontology. The invention includes a system enabling a curator, or other person, to verify the validity of assertions created by predetermined rules. The curator may also manually edit, delete, or add assertions to an ontology.

Abstract: The invention relates generally to a system and method for creating custom multi-relational ontologies. The invention includes a system and method for creating a master ontology and the application of one or more customizing constraints to the master ontology. Also provided are methods for creating custom ontologies using path-finding and creation of custom ontologies by applying customizing constraints to extraction, assembly, curation, and publication processes.

Abstract: The invention relates to a system and method for knowledge capture using multi-relational ontologies. The system may enable an ontology service provider to ascertain the scope of an entity's knowledge capture needs, create one or more base ontologies from publicly available sources, and incorporate the entity's private data into one or more value-added custom ontologies.

Abstract: The invention relates to a system and method for data extraction and management in multi-relational ontology creation. The system of the invention includes selecting a corpus of documents containing information relevant to a targeted knowledge domain, extracting assertions and their constituent concepts and relationships from the corpus, and storing the assertions, wherein the extraction processes may rules and utilize natural language processing.

Abstract: The invention relates to a computer-implemented system and method for creating, editing, and utilizing one or more rules for multi-relational ontology creation and maintenance. The system may enable the creation and testing of various rules against a known “test-corpus.” The system may then utilize these various rules to extract and curate assertions into one or more multi-relational ontologies.
