| 20080245560 | Combined environmental-electromagnetic rotary seal - A combined environmental and electromagnetic rotary seal. The invention is adapted for use between two mutually rotating components of an electromagnetic energy transmission system and provides simultaneous protection against contamination from the environment and unwanted electromagnetic leakage. In the illustrative embodiment, a first set of grooves is cut into the exterior of a first conductive cylindrical component whose interior contains a portion of a millimeter-wave beam waveguide energy transmission system, the grooves comprising the electromagnetic portion of the seal and a second set of grooves is cut into the interior of the conductive housing enclosing the first conductive cylindrical component. The second set of grooves comprises the environmental portion of the seal when a set of standard environmental seals (such as elastomeric o-ring seals) are seated in each groove in the second set of grooves and each seal is compressed between the groove in which it is seated and the exterior of the first conductive cylindrical component. The environmental seals maintain a nearly uniform annular gap between the first conductive cylindrical component and the conductive housing such that the two conductors do not make physical contact. | 10-09-2008 |

| 20090174621 | Methods and Apparatus for Multilayer Millimeter-Wave Window - Methods and apparatus for a multilayer millimeter-wave window according to various aspects of the present invention operate in conjunction with a multilayer window that is substantially transparent to a passing millimeter-wave. The window may include multiple perforations in a thermally conductive element to be disposed in the path of the passing wave. A dielectric is positioned between each thermally conductive element and acts as a seal between wave source and an ambient environment. The window may also be configured to conform to a contoured surface or structure. | 07-09-2009 |
| 20100259447 | WIRELESS POWER TRANSMISSION SYSTEM AND METHOD - A wireless power transmission system including at least one source of electromagnetic radiation, a plurality of wireless power receivers that receive radiated electromagnetic energy, a beacon collocated with each wireless power receiver, wherein the beacon generates and radiates a pilot signal when the beacon is in an active state, and an array of transmitting antennas connected to the source of electromagnetic radiation that radiates the electromagnetic radiation in the direction of the beacon in the active state. The electromagnetic radiation can be electronically steered from one wireless power receiver to another by activating and deactivating the beacons collocated with each wireless power receiver. | 10-14-2010 |

| 20090070298 | Iterators for Applying Term Occurrence-Level Constraints in Natural Language Searching - Tools and techniques are described that relate to iterators for applying term occurrence-level constraints in natural language searching. These tools may receive a natural language input query, and define term occurrence-level constraints applicable to the input query. The methods may also identify facts requested in the input query, and may instantiate an iterator to traverse a fact index to identify candidate facts responsive to the input query. This iterator may traverse through at least a portion of the fact index. The methods may receive candidate facts from this iterator, with these candidate facts including terms, referred to as term-level occurrences. The methods may apply the term occurrence-level constraints to the term-level occurrences. The methods may select the candidate fact for inclusion in search results for the input query, based at least in part on applying the term occurrence-level constraint. | 03-12-2009 |
| 20090076799 | Coreference Resolution In An Ambiguity-Sensitive Natural Language Processing System - Technologies are described herein for coreference resolution in an ambiguity-sensitive natural language processing system. Techniques for integrating reference resolution functionality into a natural language processing system can processes documents to be indexed within an information search and retrieval system. Ambiguity awareness features, as well as ambiguity resolution functionality, can operate in coordination with coreference resolution. Annotation of coreference entities, as well as ambiguous interpretations, can be supported by in-line markup within text content or by external entity maps. Information expressed within documents can be formally organized in terms of facts, or relationships between entities in the text. Expansion can support applying multiple aliases, or ambiguities, to an entity being indexed so that all of the possibly references or interpretations for that entity are captured into the index. Alternative stored descriptions can support retrieval of a fact by either the original description or a coreferential description. | 03-19-2009 |
| 20090138454 | Semi-Automatic Example-Based Induction of Semantic Translation Rules to Support Natural Language Search - Technologies are described herein for generating a semantic translation rule to support natural language search. In one method, a first expression and a second expression are received. A first representation is generated based on the first expression, and a second representation is generated based on the second expression. Aligned pairs of a first term in the first representation and a second term in the second representation are determined. For each aligned pair, the first term and the second term are replaced with a variable associated with the aligned pair. Word facts that occur in both the first representation and the second representation are removed from the first representation and the second representation. The remaining word facts in the first representation are replaced with a broader representation of the word facts. The translation rule including the first representation, an operator, and the second semantic representation is generated. | 05-28-2009 |

| 20090063426 | IDENTIFICATION OF SEMANTIC RELATIONSHIPS WITHIN REPORTED SPEECH - Methods and computer-readable media for associating words or groups of words distilled from content, such as reported speech or an attitude report, of a document to form semantic relationships collectively used to generate a semantic representation of the content are provided. Semantic representations may include elements identified or parsed from a text portion of the content, the elements of which may be associated with other elements that share a semantic relationship, such as an agent, location, or topic relationship. Relationships may also be developed by associating one element that is in relation to, or is about, another element, thereby allowing for rapid and effective comparison of associations found in a semantic representation with associations derived from queries. The semantic relationships may be determined based on semantic information, such as potential meanings and grammatical functions of each element within the text portion of the content. | 03-05-2009 |
| 20090063473 | INDEXING ROLE HIERARCHIES FOR WORDS IN A SEARCH INDEX - Methods, systems and computer readable media for finding documents in a data store that match a natural language query submitted by a user are provided. The documents and queries are matched by determining that words within the query have the same relationship to each other as the same words in the document. Documents are semantically analyzed and words in the document are indexed along with the role the word plays in a sentence. The initial semantic role may be generalized using a role hierarchy and stored in the index along with the original role. A similar analysis may be used with the search query to find words used in the same role in both the query and the document. | 03-05-2009 |
| 20090070322 | BROWSING KNOWLEDGE ON THE BASIS OF SEMANTIC RELATIONS - Computer-readable media and computer systems for conducting semantic processes to facilitate navigation of search results that include sets of tuples representing facts associated with content of documents in response to queries for information. Content of documents is accessed and semantic structures are derived by distilling linguistic representations from the content. Groups of two or more related words, called tuples, are extracted from the documents or the semantic structures. Tuples can be stored at a tuple index. Representations of the relational tuples are displayed in addition to documents retrieved in response to a query. | 03-12-2009 |
