Title: Policy driven, credntial delegat10n for single sign on and secure access to network resources
Inventor: MEDVINSKY GENNADY
IPC: H04L9/32
Filed: 2007-05-25
Abstract: A credential security support provider (Cred SSP) enables any application to securely delegate a user's credentials from the client, via client side Security Support Provider (SSP) software, to a target server, via server side SSP software. The Cred SSP provides a secure solution based in part upon a set of policies. The policies can be for any type of user credentials and the different policies are designed to mitigate a broad range of attacks so that appropriate delegation can occur for given delegation circumstances, network conditions, trust levels, etc. Additionally, only a trusted subsystem, e.g., a trusted subsystem of the Local Security Authority (LSA), has access to the clear text credentials such that neither the calling application of the Cred SSP APIs on the server side nor the calling application of the Cred SSP APIs on the client side have access to clear text credentials.

Abstract: 본 발명은 양면 광전지 모듈의 온도를 감소시키기 위한 열 저 감 장치에 관한 것으로서, 
     광 발전 시스템에 사용되고 있는 광전지에서 전자 및 정공의 생성과 온도의 상승은 광전지 표면에 입사되는 빛의 양에 비례하게 되나, 광전지의 온도 상승은 저항의 증가 효과를 가져와서, 광전지의 출력을 떨어뜨리게 되므로, 광 전 변화 효율을 고려하여 온도 상승을 억제하는 열 저 감 장치가 필요하다.  
     양면 광전지 모듈의 형태는 H와 같이 양쪽 면에 광전지 표면을 갖추고 있으며, 양쪽 광전지 표면 각 각에는 광전지 표면의 몇 배가되는 빛이 반사경에 의해 반사되어 입사되므로, 자연 입사광보다는 상승 최대 온도가 높아진다. 
     이와 같은 광전지 모듈의 상승 온도를 일정한 온도 이하로 억제하기 위하여, 양쪽에 있는 광전지와 광전지 사이에 열 매체 이송 파이프를 두어서, 열 매체로 광전지의 열을 전도시켜서, 광전지의 열을 외부로 배출시킨다. 
     이와 같이 본 발명은 양면 광전지 모듈에 새로운 열 저 감 장치를 도입하여, 온도의 상승에 따른 광 전 변환 효율의 저하를 막는 특징을 갖추고 있다.
