Abstract: 본 발명은 수문을 승하강시키면서 수로를 개폐토록 함에 있어 수문의 파손을 방지함은 물론 이물질이 수문과 바닥면 사이에 끼었을 때 쉽게 인지할 수 있도록 한 승강식 권양기 수문의 구성방법에 관한 것이다. 
     이러한 본 발명은 수직방향으로 된 수문의 상부에는 수문과 일정거리 이격되게 권양기를 설치하고, 권양기와 수문의 사이에는 승강부재를 연결하여 수문이 권양기에 의해 승하강할 수 있도록 구성하되, 수문은 중공상태로 구성하고 그 중간에 지지판을 구비하며, 승강부재의 하단부에는 지지판을 슬라이딩 가능하게 통과한 상태에서 지지판의 저부에 걸릴 수 있도록 지지편을 결합 구성한 것으로, 승강부재가 상승되면 수문이 따라 상승할 수 있으나, 수문 하강시 수문이 이물질에 의해 중간에 멈추더라도 승강부재는 수문을 그대로 둔채 하강할 수 있어 수문을 안전하게 보호할 수 있는 것이며, 수문이 중간에 멈춘 만큼 이물질체크바가 권양기의 상부로 노출되므로 관리자는 이를 보고 손쉽게 이물질 여부를 인식할 수 있어 신속한 대처가 가능해지는 것이다.

Title: System and method for bandwidth allocation in gpon
Inventor: KIM YU GUN
IPC: H04L12/28
Filed: 2005-12-08
Abstract: A GPON(Gigabit-capable Passive Optical Network) system and a method for allocating bandwidths therein are provided to efficiently allocate bandwidths in consideration of fairness between ONUs(Optical Network Units) and T-CONT(Traffic-Container) priorities by allocating a minimal bandwidth to each ONU and proportionally assigning an additional bandwidth according to the T-CONT priority of each ONU. An OLT(Optical Line Terminal) sets 'i', a variable indicating the number of ONUs, to '1'(S401). The OLT, receiving a bandwidth allocation request from an ONU, checks whether the requested bandwidth is larger than Min_BWi, the minimum bandwidth of the ONU(S402). If so, the OLT allocates Min_BWi to the ONU(S403). If not, the OLT allocates the requested bandwidth only(S404). Then, the OLT judges whether the value of 'i' is identical to the total number of ONUs within the system(S405). If so, the OLT completes the minimum bandwidth allocation procedures. The OLT sets 'k', a variable indicating T-CONT classes, to '1' in order to start dynamic bandwidth allocation procedures(S407). The OLT requests each ONU to report whether a T-CONT to which a bandwidth hasn't been allocated exists. Confirming that a remaining bandwidth exists and that a T-CONT which a bandwidth hasn't been allocated exists, the OLT calculates a bandwidth to be allocated to 'K', T-CONT classes based on a weight granted to 'k'(S409). The OLT checks whether the value of 'k' reaches the number of the whole T-CONT classes(S410).

Abstract: Fast on-line electro-optical detection of wafer defects by illuminating with a short light pulse from a repetitively pulsed laser, a section of the wafer while it is moved across the field of view of an imaging system, and imaging the moving wafer onto a focal plane assembly, optically forming a continuous surface of photo-detectors at the focal plane of the optical imaging system. The continuously moving wafer is illuminated by a laser pulse of duration significantly shorter than the pixel dwell time, such that there is effectively no image smear during the wafer motion. The laser pulse has sufficient energy and brightness to impart the necessary illumination to each sequentially inspected field of view required for creating an image of the inspected wafer die. A novel fiber optical illumination delivery system, which is effective in reducing the effects of source coherence is described. Other novel aspects of the system include a system for compensating for variations in the pulse energy of a Q-switched laser output, methods for autofocussing of the wafer imaging system, and novel methods for removal of repetitive features of the image by means of Fourier plane filtering, to enable easier detection of wafer defects.
