20100287220 | Dynamically Encoding Types and Inhabitants in a Relational Database - Described is a technology, such as for representing scientific data and information, in which a database table contains rows of type data representing types, and term data representing terms that inhabit the types. Types include composite types (e.g., that represent entities), and instances of relation types that express relationships between types, between a type and a term, or between terms. Types and/or terms may have multiple relationships with one another, and a relationship may span database tables. A new relationship may be established by adding a new row to the database table to represent a new relation term, along with one or more similar rows to represent the relation role terms associated with that relation term; relationships may be removed by removing rows. As a result, the database table may change its state rapidly, without needing to change the database schema. | 11-11-2010 |
20110320431 | STRONG TYPING FOR QUERYING INFORMATION GRAPHS - Described herein is using type information with a graph of nodes and predicates, in which the type information may be used to determine validity of (type check) a query to be executed against the graph. In one aspect, each node has a type, and each predicate indicates a valid relationship between two types of nodes. A type checking mechanism uses the type information to determine whether a query is valid, which may be the entire query prior to query processing/compilation time, or as the query is being composed by a user. One or more valid predicates for a given node may be discovered based upon the node type, such as discovered to assist the user during query composition. Also described is using the type information to optimize the query. | 12-29-2011 |
20120158636 | EFFICIENT PROBABILISTIC REASONING OVER SEMANTIC DATA - A semantic reasoning engine is described for performing probabilistic reasoning over a semantic graph in a time-efficient and viable manner. The semantic reasoning engine includes a data store that provides the semantic graph, where the semantic graph is formed by a plurality of concepts connected together via probabilistic assertions. The semantic reasoning engine operates by providing an answer to a query by recursively collapsing the semantic graph based on at least one collapsing rule. | 06-21-2012 |
20120166378 | FORWARD CHAINING AS AN ORCHESTRATION MECHANISM FOR ANALYTICS - A method and system of using a forward chaining application on a computing device to monitor a semantic storage system and invoke computations on scientific data according to declarative rules, while capturing operational provenance data stored alongside the scientific data where all data is stored in a semantic graph is disclosed and described. As the provenance data is stored with the data as nodes in the semantic graph, it will stay with the data and may be searched and queried using the same methods as searching the underlying data. | 06-28-2012 |
20140160432 | Self-Aligning Unobtrusive Active Eye Interrogation - Methods and system for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The gaze direction of the eye of the subject is determined and an interrogation signal source and/or response signal sensor are moved into alignment with the eye using an actuator to facilitate detection of the signal from the eye of the subject. | 06-12-2014 |
20140160433 | Unobtrusive Active Eye Interrogation - Methods and systems for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The physiological parameter is determined from a signal sensed from the eye of a subject when the eye of the subject is properly aligned with regard to an interrogation signal source and/or response signal sensor. | 06-12-2014 |
20140160434 | Time-Based Unobtrusive Active Eye Interrogation - Methods and systems for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The physiological parameter is determined from a signal sensed from the eye of a subject according to a schedule, under the control of a scheduling controller. | 06-12-2014 |
20140163329 | Unobtrusive Active Eye Interrogation with Gaze Attractor - Methods and systems for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The system includes a gaze attractor for attracting the gaze of the subject to cause an eye of the subject to move into alignment with regard to an interrogation signal source and/or response signal sensor to facilitate detection of a signal from the eye of the subject. | 06-12-2014 |
20150070652 | UNOBTRUSIVE ACTIVE EYE INTERROGATION - Methods and systems for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The physiological parameter is determined from a signal sensed from the eye of a subject when the eye of the subject is properly aligned with regard to an interrogation signal source and/or response signal sensor. | 03-12-2015 |
20150070653 | UNOBTRUSIVE ACTIVE EYE INTERROGATION - Methods and systems for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The physiological parameter is determined from a signal sensed from the eye of a subject when the eye of the subject is properly aligned with regard to an interrogation signal source and/or response signal sensor. | 03-12-2015 |
20150070654 | SELF-ALIGNING UNOBTRUSIVE ACTIVE EYE INTERROGATION - Methods and system for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The gaze direction of the eye of the subject is determined and an interrogation signal source and/or response signal sensor are moved into alignment with the eye using an actuator to facilitate detection of the signal from the eye of the subject. | 03-12-2015 |
