Abstract:
Disclosed herein is an electronic component-embedded printed circuit board, including: a metal substrate including an anodic oxide film formed over the entire surface thereof; two electronic components disposed in a cavity formed in the metal substrate in two stages; an insulation layer formed on both sides of the metal substrate to bury the electronic components disposed in the cavity; and circuit layers including vias connected with connecting terminals of the electronic components and formed on the exposed surfaces of the insulation layer. The electronic component-embedded printed circuit board is advantageous in that its radiation performance of radiating the heat generated from an electronic component can be improved, and its production cost can be reduced, because a metal substrate is used instead of a conventional insulating material.

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.
