20110072135 | Generalized Policy Server - A scalable access filter that is used together with others like it in a virtual private network to control access by users at clients in the network to information resources provided by servers in the network. Each access filter use a local copy of an access control database to determine whether an access request made by a user. Changes made by administrators in the local copies are propagated to all of the other local copies. Each user belongs to one or more user groups and each information resource belongs to one or more information sets. Access is permitted or denied according to of access policies which define access in terms of the user groups and information sets. The rights of administrators are similarly determined by administrative policies. Access is further permitted only if the trust levels of a mode of identification of the user and of the path in the network by which the access is made are sufficient for the sensitivity level of the information resource. If necessary, the access filter automatically encrypts the request with an encryption method whose trust level is sufficient. The first access filter in the path performs the access check and encrypts and authenticates the request; the other access filters in the path do not repeat the access check. A policy server component of the access filter has been separated from the access filter and the policies have been generalized to permit administrators of the policy server to define new types of actions and new types of entities for which policies can be made. Policies may now further have specifications for time intervals during which the policies are in force and the entities may be associated with attributes that specify how the entity is to be used when the policy applies. | 03-24-2011 |

20090074731 | METHOD OF ISOLATION AND USE OF CELLS DERIVED FROM FIRST TRIMESTER UMBILICAL CORD TISSUE - A method of isolating a pluripotent cell from human umbilical cord is described herein. The method involves collecting a sample of umbilical cord from fetal tissue obtained at less than 20 weeks of gestation, for example a first trimester umbilical cord. The sample is treated to obtain isolated umbilical cord cells, after which the isolated umbilical cord cells are incubated. Stem cells obtained in this way can be differentiated for use in therapeutic applications. | 03-19-2009 |
20090317812 | METHOD OF DETECTING PREECLAMPSIA - The invention provides a method for detecting a propensity toward or risk of developing preeclampsia, comprising detecting in a female subject the presence of a single base pair point mutation, ΔA at position +1754, in the HLA-G mRNA 3′UTR. The mutation is associated with preeclampsic subjects, and with decreased RNA stability in vitro. The presence of this ΔA mutation may provide an explanation for lower levels of HLA-G expression seen in association with preeclampsia. | 12-24-2009 |

20080248693 | SHIELDLESS, HIGH-SPEED ELECTRICAL CONNECTORS - A shieldless, high-speed electrical connector is disclosed. Such a connector may include a first column of electrical contacts comprising a first arrangement of differential signal pairs separated from one another by first ground contacts, and a second column of electrical contacts adjacent to the first column, the second column of electrical contacts comprising a second arrangement of differential signal pairs separated from one another by second ground contacts. The connector may be devoid of electrical shield plates between the first column of electrical contacts and the second column of electrical contacts. The connector may be capable of transferring differential signals at data transfer rates of at least ten gigabits per second through the connector while producing no more than an acceptable level of cross talk on any of the differential signal pairs. | 10-09-2008 |
