    • Disclosed herein is a printed circuit board including embedded capacitors, composed of a polymer condenser laminate including a plurality of polymer condenser layers, each of which has a polymer sheet and a conductor pattern formed on the polymer sheet, and a via hole for interlayer connection therethrough, and a circuit layer formed on either surface or both surfaces of the polymer condenser laminate and having a circuit pattern and a via hole for interlayer connection therethrough. The printed circuit board of the current invention has higher capacitance density per unit area than conventional embedded capacitor printed circuit boards, whereby capacitors having various capacitance values, such as multilayered ceramic capacitors having high capacitance, can be embedded in the printed circuit board, instead of being mounted thereon. Also, a method of manufacturing the printed circuit board including embedded capacitors is provided.

    • Disclosed is a method of forming a pattern on a mask sheet including an attaching portion to be attached to a mask frame, and a pattern area in which the pattern is formed. The method includes positioning the mask sheet on an auxiliary sheet with a thickness greater than the thickness of the mask sheet, fastening the auxiliary sheet to the mask frame, applying a stretching force to the mask sheet and the auxiliary sheet, and forming the pattern on the pattern area of the mask sheet. Thus, a predetermined pattern is formed on a mask sheet while a uniformly distributed external force is applied to the mask sheet, so that bending or deflecting out of plane by the mask sheet is prevented, thereby forming a precise mask pattern.
    • 公开了一种在掩模板上形成图案的方法,该掩模板包括附着到掩模框架的附接部分和形成图案的图案区域。 该方法包括将掩模片定位在厚度大于掩模片的厚度的辅助片上,将辅助片固定到掩模框架上,向掩模片和辅助片施加拉伸力,并将形状形成在 掩模片的图案区域。 因此,在均匀分布的外力施加到掩模片上时,在掩模板上形成预定图案,从而防止由掩模片弯曲或偏转出平面,从而形成精确的掩模图案。

    • Provided are a system and method for position awareness that can be used indoors in a large-scale environment and can minimize generation of radio frequency (RF) and ultrasonic waves in a wireless sensor network including low-priced sensor nodes capable of precise position measurement, thus improving energy efficiency by reducing unnecessary power consumption. The method includes the steps of: (a) calculating initial position coordinates using beacon information received from adjacent beacons through a broadcast beacon solicitation signal, sending a synchronization signal to the beacons, and synchronizing the beacons; (b) receiving ultrasonic waves generated from the adjacent beacons activated by a broadcast start message, and calculating position coordinates; and (c) when the calculated position coordinates correspond to a predetermined hand-off threshold position, transmitting a hand-off process message to a newly activated beacon, and executing a hand-off process routine.
