Use of credentials in this manner enables a wide variety of relatively complex and flexible control arrangements to be put in place and enforced with relatively simple rights management technology.

US09946828B2 Integrated circuit and method of designing layout thereof
A method of designing a layout of an integrated circuit (IC), which is implemented by a computer system or a processor, includes receiving input layout data, and performing a design rule check with regard to a plurality of patterns. The method includes, merging, from among a first pattern and a second pattern against the design rule, the first pattern with a third pattern connected to a same net as the first pattern, and generating output layout data.
US09946822B2 Fly-height interaction simulation
In an approach for providing simulation results of an interaction between a transducer head and a magnetic medium, a computer identifies a first raster scan of a sample via a scanning probe microscope. The computer generates a topography image based on the first raster scan of the sample. The computer identifies one or more reference features within the created topography image. The computer calculates an average height based on the one or more reference features. The computer determines a lift distance associated with a probe of the scanning probe microscope. The computer defines a uniform plane based on the calculated average height and the determined lift distance. The computer performs a second raster scan of the sample based on the defined uniform plane. The computer generates a fly-height image based on the second raster scan. The computer provides simulation results based at least in part on the second raster scan.
US09946816B2 System for visualizing a three dimensional (3D) model as printed from a 3D printer
A system and a method visualize three dimensional (3D) printability of a 3D model. A 3D printing process of the 3D model is simulated to generate a layered 3D model describing the 3D model as printed. A visual rendering of the layered 3D model is generated, and the visual rendering of the layered 3D model is displayed on a display device.
US09946806B2 Exporting responsive designs from a graphical design tool
Embodiments of the present invention provide tools and methods for the development and specification of a responsive graphical design. A graphical design environment allows a user to specify a design. The graphical design environment has a window for displaying a rendering of the design. A dimension specification interface allows the user to specify a dimension specification. A widget interface allows a user to add a widget to the design and specify a first state and a second state for the widget. An export interface allows a user to export the design from the tool to produce an exported design. The exported design utilizes an object model event to adjust a state of the widget from a first state to a second state.
US09946805B2 System and method for displaying services capable of pasting document stored on a cloud-based cross-clipboard
Provided is a cloud-based document link system and a method that uses a processor to provide a method for providing a service configured to paste a document stored on a cross-clipboard. The cloud-based document link system includes a storage unit configured to store, on a cross-clipboard, at least one first document associated with a first service provided through a first device, an identification unit configured to identify at least one second service linkable with each first document based on whether the at least one second service is configured to paste the at least one first document stored on the cross-clipboard, and a providing unit configured to provide a list of each second service if the cross-clipboard is accessed through a second device.
US09946804B2 Displaying historical data associated with data values within business intelligence reports
The current subject matter describes displaying historical data associated with one or more data values within a business intelligence report. A graphical user interface executed by a computing device can receive, from a user, a request for display of historical data associated with a specified/selected data value in a business intelligence report. Subsequently, a representational state transfer engine (RESTful engine), which can be connected to a server system connected to the computing device, can execute a representational state transfer service (RESTful service) to fetch historical data from current and past instances associated with the data value. Then, the RESTful engine can write the fetched historical data to a file. The RESTful engine can generate or determine a uniform resource locator (URL) to the file, and can send the URL to the computing device. When the URL is selected by the user, the computing device can display the file.
US09946776B1 Systems and methods for importing data from electronic data files
Computer implemented systems and methods are disclosed for importing data from electronic data files. In accordance with some embodiments, source electronic data files are received at a data importation system and managed by the data importation system. The data importation system may load detector/transformer plugins and determined whether any of the load detector/transformer plugins apply to the received source electronic data files. The data importation system may also generate transformed data using a transformer corresponding to a detector that applies to the source electronic data files. The data importation system may import the transformed data into at least one of a data analysis system and a database.
US09946773B2 Graphical keyboard with integrated search features
A computing device may include a presence-sensitive display, at least one processor, and a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to output, for display at the presence-sensitive display, a graphical keyboard including a plurality of keys and a suggestion region; determine, based on a selection of the suggestion region or one or more keys from the plurality of keys, a search query; retrieve one or more search results determined based on the search query; and output, in place of at least a portion of the graphical keyboard, a visual representation of a particular search result of the one or more search results.
