    • 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.
    • 本发明涉及使用边界监视查询的数据流的处理方法,更具体地说,涉及一种数据流的监视方法和系统,该数据流是大量的数据并连续生成的,例如金融报价单,GPS数据或普遍存在的传感器网络 (USN)。 本发明的目标是以高性能和可扩展的方式处理数据流上的大量BMQ。 为此,本发明提出了可扩展和高性能的数据流监测框架BMQ-Index。 BMQ-Index的主要思想是共享和增量处理。 对于共享处理,BMQ-Index采用查询索引方式,从而实现了高度的可扩展性。 一旦BMQ-Index建立在注册查询上,只有在输入数据时快速搜索相关查询。 对于增量处理,BMQ-Index使用增量访问方法,即用于存储增量查询信息和增量搜索算法的索引结构。 因此,连续的BMQ评估大大加快。

    • A high luminance and high output LED package using an LED as a light source and a fabrication method thereof. The LED package includes an Al substrate with a recessed multi-stepped reflecting surface formed therein and a light source composed of LEDs mounted on the reflecting surface and electrically connected to patterned electrodes. The LED package also includes anodized insulation layers formed between the patterned electrodes and the substrate, and an encapsulant covering over the light source of the substrate. The LED package further includes an Al heat radiator formed under the LEDs to enhance heat radiation capacity. According to the present invention, the substrate is made of Al material and anodized to form insulation layers thereon, allowing superior heat radiation effect of the LED, thereby significantly increasing the lifetime and light emission efficiency of the LED package.
