Abstract: The present invention relates to a processing method of data stream using Border Monitoring Query, and more particularly a monitoring method and a system for data streams which are a large volume of data and continuously generated such as financial ticker, GPS data or a ubiquitous sensor network (USN).The objectives of the present invention are to process a large number of BMQs over data streams in high-performance and scalable manner. For this purpose, the invention presents BMQ-Index, a scalable and high performance data stream monitoring framework. The main idea of BMQ-Index is shared and incremental processing. For shared processing, BMQ-Index adopts a query indexing approach, thereby achieving a high level of scalability. Once BMQ-Index is built on registered queries, only relevant queries are quickly searched for upon an incoming data. For incremental processing, BMQ-Index employs an incremental access method, i.e., an index structure to store delta query information and an incremental search algorithm. Thus, successive BMQ evaluations are greatly accelerated.

Abstract: An optical pickup actuator includes a base having a holder installed at one side thereof, a moving portion in which an objective lens is installed at the periphery thereof and a guide hole is formed, a bobbin coupled to the guide hole, a magnetic driving portion provided at the base and symmetrically arranged to make the moving portion perform focusing and tracking, and suspensions having one end supported at the holder and the other end fixed to the moving portion to be connected to the bobbin. Thus, since the magnetic driving portion is symmetrically arranged, a pitching mode and a rolling mode generated due to an asymmetrical structure are prevented. Also, the AC sensitivity and DC sensitivity can be improved.

Abstract: An optical pickup having a blade including a first blade in which an objective lens is mounted and which is made of a reinforced plastics material, and a second blade in which driving coils are mounted and which is made of a magnesium alloy material. Since the first blade has a low thermal conductivity coefficient, the heat generated in the coils is prevented from being transferred to the objective lens, whereas the second blade having a high thermal conductivity coefficient radiates the heat generated by the coils to the outside. Thus, the heat distortion of the objective lens can be suppressed, and damages to the coils or rigidity reduction of the blade can be avoided.

Abstract: Magnets, which have a surface facing a coil, through which current flows, generate magnetic flux to be emitted toward the coil in the direction of the normal line of the surface of the magnets toward the coil, the magnets having a recession or protrusion formed at the center thereof. The magnets form magnetic flux to be regularly generated and thus can generate uniform electromagnetic forces through interaction with current.
