A disclosed display apparatus may include a display panel having a plurality of sub-pixels and configured to display an image based on an image signal provided to the display panel; a controller configured to determine a required power for at least one frame of the image signal and to output a switch signal based on determining if the required power is equal to or higher than a predetermined reference power; and a power supply device configured to receive an external AC power and to generate a first high-level voltage and a second high-level voltage. The power supply device may be further configured, based on the switch signal, to output the first high-level voltage to drive the display panel, or to combine the second high-level voltage with the first high-level voltage to generate a third high-level voltage and to output the third high-level voltage to drive the display panel.

The chuck for supporting a target substrate for a display device, the chuck includes: a base having a first surface to support an object and a second surface opposite the first surface, the first surface including a first area and a second area; and indentations formed in the second area and recessed from the first area in a thickness direction of the base. The indentations include a first indentation extending in a first direction and a second indentation extending in a second direction intersecting the first direction.

A system and method for hybrid Rete reasoning based on memory and DBMS are provided. The system for hybrid Rete reasoning based on memory and DBMS includes a reasoning rule type classification means for classifying an input reasoning rule as one of one or more types. A network generation means generates a network depending on the classified reasoning rule type. A network execution means derives extended triples by applying a predetermined triple to the generated network.

An efficient reasoning system and method using a view in a DBMS-based RDF triple store are provided. The DBMS-based reasoning system includes a triple input unit for receiving a Resource Description Framework (RDF) triple. A triple examination unit examines whether the received triple conforms to RDFS subsumption relation entailment rules or Web Ontology Language (OWL) inverse relation rules. A view creation unit creates a table view when the received triple conforms to the RDFS subsumption relation entailment rules or the OWL inverse relation rules as a result of the examination. A triple storage unit stores the received triple. The DBMS-based triple store can efficiently perform reasoning based on rule rdfs7 or rdfs9, which is included in the RDFS subsumption relation entailment rules, and the OWL inverse relation rules.

Rule reasoner includes: a Rete network builder for receiving ontology, including ontology instance represented by triple and ontology schema defining classes and properties of the triple, and reasoning rule, building Rete network corresponding to the ontology and the reasoning rule, selecting clue pattern corresponding to wild pattern rule with reference to the ontology schema when reasoning rule having wild pattern is received, rewriting the wild pattern rule with reference to the clue pattern, and adding test node, alpha memory node, and wild rule node so that the rewritten wild pattern rule is incorporated; a Rete network implementer for generating reasoned triple by implementing the Rete network built by the Rete network builder or generating reasoning rule where the wild pattern rule is dynamically materialized; and a Rete network expander expanding the Rete network by inputting the new reasoning rule, generated by the Rete network implementer, to the Rete network builder.

A system for detecting the presence and direction of an object passing through a gate, for example, a door of a building or a room, and announcing the detection result to the operator or persons in the building or the room. The system detects an object passing through a gate supported laterally by a frame. The system comprises a reflector, signal generating and determining means, and a user interface. The reflector is disposed at an edge of the frame. The signal generating and determining means is disposed at the other edge of the frame so as to face the reflector. The signal generating and determining means generates a first and a second infrared beams to emit to the reflector, receives a mixed beam in which the first and the second beams reflected by the reflector are superimposed, and determines the presence and direction of the object passing through the gate based on the mixed beam. The user interface notifies a user of the presence and direction of the object when the object passes through the gate and receives an operation command from the user. The signal generating and determining means comprises first and second infrared emitters for generating the first and the second infrared beams, respectively. The first and the second infrared emitters are mounted in a single housing.
