Title: Constraint based routing with non-transitive exceptions
Inventor: SKALECKI DEREK
IPC: H04L12/56
Filed: 2003-09-11
Abstract: In a multiple element network, a method and network element for providing a constraint based routing system to accommodate non-transitive exceptions. The method and network element receive a connection request for an end to end connection. The network element can select routing information having a pair of adjacent links associated with the multiple elements of the network, where each link of the pair of links has a shared network resource.  The shared network resource is compared to a database of exception sets, the exception sets including at least one non-transitive exception predetermined from a plurality of network resources.  The network element confirms whether the shared network resource of the selected pair of links is contained within the exception database. A router designs a pathway over the network for the end to end connection using the results of the shared network resource comparison, wherein inclusion in the pathway is inhibited for the shared network resource matching the predetermined exclusion set contained in the database. Accordingly, the list of exception sets is accessible by a constraint based routing algorithm as input to exclude the selected link pair of a pathway for the end to end connection over the network, if the shared network resource of the link pair is contained within the exception sets.

IPC: G06F9/44
Filed: 2002-03-11
Abstract: A computer program and method facilitate operation of a screen reader with legacy programs whose user interface definitions do not conform to the design guidelines expected by the screen reader program. The method involves:  analyzing a graphical user interface to identify a logical sequence of user interface elements within the interface; comparing the sequence of user interface elements within a definition of the user interface with the identified logical sequence, to identify any required reordering of the elements to conform to the identified logical sequence; and performing the required reordering of the elements to conform to the identified logical sequence. One or more lists or tables is generated for each separable user interface component (such as a dialog) to specify the required sequence for reordering incorrectly-sequenced user interface controls within the definition, and to identify a new static text control which is dynamically generated for use with an edit control which does not have a required static text control.

Title: Multimerization of hiv-1 vif protein as a therapeutic target
Inventor: ZHANG HUI
IPC: A61P31/18
Filed: 2002-04-08
Abstract: One approach to treating individuals infected with HIV-1 is to administer to such individuals compounds that directly interfere with and intervene in the machinery by which HIV-1 replicates itself within human cells. Although the specific role of HIV-1 viral protein Vif in the viral life cycle is not known, the Vif gene is essential for the pathogenic replication of lentivirusesin vivo. The present invention relates to a method for treating an individual exposed to or infected with HIV-1. Individuals identified as being exposed to or infected by HIV-1 are administered a therapeutically effective amount of one or more compounds that inhibit or prevent replication of said HIV-1 by interfering with the replicative or other essential functions of HIV-1 viral protein Vi, by interactively blocking the multimerization domain of Vif, thereby preventing multimerization of Vif protein, which is important for Vif function in the lentivirus life cycle. In preferred embodiments, the compound or compounds that interactively block the multimerization domain of Vif are Vif antagonists. Pharmaceutical compositions comprising these compounds are also disclosed.

Title: Microstructures for delivering a composition cutaneously to skin using rotatable structures
Inventor: GARTSTEIN VLADIMIR
IPC: A61B17/00
Filed: 2002-09-13
Abstract: An improved method and apparatus (600) is provided as a system to deliver a composition, preferably a medical or pharmaceutical composition or active, through the stratum corneum of skin, without introducing bleeding or damage to tissue, and absent pain or other trauma. The dimensions and shapes of the microelements (12) are controlled so as to control the penetration depth into the skin. The microelements can be "hollow" such that passageways (626) are created therethrough to allow the composition to flow from a chamber (476), through the microelements, and into the skin. Alternatively, the microelements can be "solid" (622), and the composition is applied directly to the skin just before or just after the microelements are applied to the skin surface to create the openings in the stratum corneum. Another alternative embodiment uses cylindrical microstructures that are rotatably applied to the skin and which penetrate through the stratum corneum; and which can dispense fluid by various different structures.
