  • NON-FOULING, ANTI-MICROBIAL, ANTI-THROMBOGENIC GRAFT-FROM COMPOSITIONS
    Publication number: 20100152708
    Abstract: Substrates, optionally coated with an undercoating layer, having grafted there from one or more non-fouling materials are described herein. The non-fouling, polymeric material can be grafted from a variety of substrate materials, particularly polymeric substrates and/or polymeric undercoating layers. The graft-from techniques described herein can result in higher surface densities of the non-fouling material relative to graft-to formulations. Graft-from methods can be used to produce covalently tethered polymers. The compositions described herein are highly resistant protein absorption, particularly in complex media and retain a high degree of non-fouling activity over long periods of time. The compositions described herein may also demonstrate antimicrobial and/or anti-thrombogenic activity.

  • PRESERVING A COMPLETE HISTORY OF A SET OF APPLICATION ACTIONS WHEN NON-LINEAR INTERACTIONS ARE PERMITTED
    Publication number: 20090327973
    Abstract: An action history maintains a set of ordered application actions associated with a user. A user interface of a software application can include a back control and a forward control, which utilize the action history. Specifically, the back control revokes a most recent action and the forward control reapplies a previously revoked action. Thus, the forward and backward controls change which page is rendered in the software application. Unlike traditional implementations, the invention maintains a complete set of actions within the action history in a non-linear context. That is, when a new action is inserted into a history from a non-terminal state (i.e., actions able to be reapplied are available upon a selection of the forward control) then the new action is inserted immediately after the current action. The historic actions are maintained in order after the new action in the action history.

  • EXTENSIBLE BROWSER PLATFORM FOR WEB APPLICATIONS
    Publication number: 20090271707
    Abstract: An enhancement to a web browser offers an extension mechanism for web applications to utilize client-side resources, thereby moving more extensibility and flexibility to the client-side. The web browser may expose some control interfaces to meet various requirements from web applications. Using the extension mechanism, the web applications are able to offload the cloud servers, function when offline, and improve performance. The extension mechanism also provides users with full control to the data passing through their web browsers.

  • Predicate Checking for Distributed Systems
    Publication number: 20090248381
    Abstract: Predicate checking in conjunction with distributed systems can enable an investigating user to check predicates in the context of instance states and/or distributed states of a distributed system. In an example embodiment, a method entails accepting distributed system simulation data and performing a simulation of a distributed system using the distributed system simulation data to create distributed system simulated states. At least a portion of the distributed system simulated states are exposed. The exposed portion of the distributed system simulated states is retrieved and stored as exposed states for the distributed system. The exposed states for the distributed system are compared to predicate states for the distributed system. If an inconsistency is detected between the exposed states and the predicate states based on the comparing at least one alarm is issued.

  • Distributed system simulation: slow message relaxation
    Patent number: 7590519
    Abstract: Distributed system simulation is enhanced by extending the simulation window. In a described implementation, the simulation window extension is facilitated with a slow message relaxation scheme. For example, especially when the simulation window is extended, slow unscheduled events can arrive at a logical process with a timestamp that is prior to (e.g., less than) the local time of a receiving logical process that is participating in a simulation. To ameliorate issues created by a slow unscheduled message and its corresponding slow unscheduled event, a current logical time of the receiving logical process is substituted for the original timestamp of the slow unscheduled event to transform it into a punctual unscheduled event.
