  • Patent number: 9195226
    Abstract: In an example embodiment, apparatus for detecting position drift in a machine operation using a robot arm, the robot arm being for operation on a semiconductor substrate, the robot arm and the semiconductor substrate being configured for relative movement therebetween, the apparatus includes an input for receiving an input signal from a sensor mounted on the robot arm; a detector for detecting, from the input signal, a detection of there being a predefined distance between the robot arm and the semiconductor substrate; wherein the apparatus is configured to determine, from the detection, whether there has been position drift.

  • Publication number: 20130020567
    Abstract: A thin film transistor may include a passivation layer formed of a metal-containing conductive material. The thin film transistor includes: a gate electrode; a gate insulating layer positioned on the gate electrode; a channel layer positioned on the gate insulating layer; a source electrode and a drain electrode which are in contact with the channel layer while being spaced apart from each other; and a passivation layer including a metal-containing conductive material and positioned on the channel layer while being spaced apart from each of the source electrode and the drain electrode. The passivation layer serves to prevent transmission of light, oxygen, water and/or impurities into the channel layer and to improve the electrical characteristics of the thin film transistor.

  • Publication number: 20070233641
    Abstract: Techniques for using arbitrary sets of objects to constrain objects in database systems. The constraint set of objects is associated with the constrained object in the database system and the database system will perform an operation which adds an object to the constrained object only if the object being added belongs to the constraint set. In a preferred embodiment, the techniques are employed to obtain constraint sets of terms from ontologies which are then used to constrain columns containing those terms. An implementation of the techniques makes a materialized view out of the objects in the constraint set and uses the materialized view to define a referential integrity constraint on the constrained column.

  • Publication number: 20060235823
    Abstract: The TABLE function mechanism available in a RDBMS is used to integrate RDF models into SQL queries. The table function invocation takes parameters including an RDF pattern, an RDF model, and an RDF rule base and returns result rows to the SQL query that contain RDF triples resulting from the application of the pattern to the triples of the model and the triples inferred by applying the rule base to the model. The RDBMS includes relational representations of the triples and the rules. Optimizations include indexes and materialized views of the representations of the triples, precomputed inferred triples, and a method associated with the TABLE function that rewrites the part of the SQL query that contains the TABLE function invocation as an equivalent SQL string. The latter technique is generally applicable to TABLE functions.

  • Publication number: 20060036592
    Abstract: The method for processing data in a relational database wherein ontology data that specifies terms and relationships between pairs of said terms expressed in an OWL document is stored in the database, database queries that include a semantic matching operator are formed which identify the ontology data and further specify a stated relationship between two input terms, and the query is executed to invoke the semantic matching operator to determine if the two input terms are related by the stated relationship by consulting said ontology data.

  • Publication number: 20060036633
    Abstract: A method for rapidly identifying terms that are associated with a given root term by a transitive relationship defined by hierarchical ontology data stored in a relational database. A transitive closure table is created that comprises a plurality of rows each of which specifies a term and an associated one of a plurality of root terms. The table is sorted and indexed by the root terms to group together rows associated with each of said root terms. The resulting transitive closure table may be consulted to rapidly identify terms associated with said given root term.

  • Publication number: 20050216518
    Abstract: A database management system that has bitmap values in which set bits in a representation of a bitstring specify a set of objects whose definitions are built into the database management system. The database management system further includes user-accessible operations on the bitmap values. The bitmap values are represented by means of a mapping specifier that specifies a range of the set of objects and a representation of a string of bits that has been mapped onto the set of object specified by the range specifier. The representation of the string of bits may be compressed. Bitmap operations on the values may alter the range specifier, the size of the string of bits, or individual bits in the string of bits. The objects represented by the bitmap values may be objects in the database management system or objects external thereto. An example of bitmap values of the first kind are bitmap values representing sets of rowids.
