  • Patent number: 9330066
    Abstract: A method for dynamic display of at least one layer in a PDF document, comprising the steps of setting at least one criterion for at least one property of a trigger to change a display state of the at least one layer of the PDF document to another display state of the at least one layer of the PDF document, creating a script that can be processed by a PDF document reader and that contains the at least one criterion for the at least one property of the trigger, and embedding the script in the PDF document, wherein when the PDF document is opened by the PDF document reader, the script causes evaluation of the at least one property for the trigger, and if the at least one criterion for the at least one property of the trigger is met, then the script causes a change of the display state of the at least one layer of the PDF document.

  • Publication number: 20150363461
    Abstract: A system for automatically updating saved query results for a graph responsive to a graph update is disclosed. The system may identify a target constraint responsive to an update to the data graph. The target constraint specifies a path in a data graph that includes an edge specified in the update. The system may determine a state for the target constraint by traversing the graph via the path and determine based on the state, that a collapsed definition for a first query that includes the constraint indicates a member node is responsive to the first query. The system may then update a saved query result for the first query using the member node identified during the traversal in accordance with the collapsed definition.

  • Publication number: 20150356277
    Abstract: A method for automating the management and interpretation of digital documents and their rights metadata to generate user access of a document protected by digital rights management (DRM), comprising the steps of a server obtaining a digital document and its associated rights metadata, the server interpreting the metadata to ascertain DRM useful information including identifications (IDs) of the document and its users and associated digital rights, and the server generating entries for a DRM database including policies associated with the document ID and users IDs based on the ascertained DRM useful information to enable DRM protection to the document.

  • Publication number: 20150271211
    Abstract: A method for managing rights management policies for user access and use of digital documents with nontraditional rights control in addition to traditional rights management services (RMS) based on digital rights management (DRM) policies assigned to respective digital documents and their users and stored in an RMS database, including the steps of: a server, upon receiving a user's request regarding a document protected by one or more DRM policies, determining whether the document has additional nontraditional rights control for the user; the server checking a nontraditional policy service (NPS) database, and validating the user's information with one or more NPS database entries of NPS policy extensions pertaining to the document and the user, where the NPS policy extensions amend the DRM policies with additional nontraditional rights control; and the server denying the user's request if the user's information cannot be validated by anyone of said one or more NPS database entries of the NPS policy extensions

  • Publication number: 20150248195
    Abstract: A user interface display method implemented on a computer-controlled device to allow an operator to define a list of selected items among a plurality of items available for selection. The operator starts by selecting a pre-existing list containing a number of selected items. A modified list is generated which initially contains the same items as the pre-existing list. The device displays all of the items available for selection, as well as first and second indications associated with each item initially in the modified list. Then, in response to operator inputs to add items to (or remove items from) the modified list, second indications are displayed (or removed from display) in association with the items to be added (or removed), without changing the display of any of the first indications and any of the plurality of items. The modified list is saved without changing the pre-existing list.

  • Patent number: 8998894
    Abstract: Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function or of vascular structures that feed or perfuse the neural fibers.

  • Publication number: 20140283124
    Abstract: A method for managing user access of a document protected by digital rights management (DRM), includes the steps of a server checking whether a user who is attempting to access a DRM-protected document has necessary rights to access the document, the server denying the user's access to the document if the user does not have the necessary rights to access the document, the server providing, if the user does not have the necessary rights to access the document, the user with an instant and pre-prepared prompt containing a unique identification (ID) of the document to direct and assist the user to complete required tasks for acquiring rights to the document, and upon completion of the required tasks by the user, the server granting the necessary rights to the user to access the document.

  • Publication number: 20130035636
    Abstract: A delivery catheter and method for delivering and deploying an implantable medical device include a mechanical latch by which the device can remain firmly attached at a single point of connection to the delivery catheter during deployment of the device. The delivery catheter provides simple yet firm control of the release mechanism to enable the clinician to confirm the accuracy of the deployment before releasing the tether or, if the placement of the device should be corrected, the tether can be maintained while the device is recaptured and repositioned or removed from the patient.

  • Patent number: 8001469
    Abstract: Systems and methods are described that automatically generate interactive systems configured for collecting dialog data of human-machine interactions in dialog systems. The systems and methods comprise receiving a task flow that describes operations of a dialog system. A formal description of the task flow is generated, and an interactive system comprising a graphical user interface (GUI) is automatically generated from the formal description. The GUI consists of templates for control of the dialog system and real-time collection and annotating of dialog data during a live dialog between only the dialog system and callers to the dialog system. The dialog data consists of data of the live dialog.
