  • Patent number: 10388000
    Abstract: Among other things, one or more techniques and/or systems are described for processing images yielded from an examination via radiation to reduce visible noise in the images. After an image is reconstructed, a noise contribution to the image (e.g., an amount of noise in the image) is estimated to determine a target noise contribution for the image. The target noise contribution for the image may vary based upon, among other things, dose of radiation, aspects or properties of an object being imaged, etc. The image is subsequently filtered using one or more filtering techniques to generate a filtered image, and a noise contribution to the filtered image is determined. When the noise contribution to the filtered image satisfies the target noise contribution (e.g., a sufficient amount of noise has been filtered out of the image), the filtered image is combined with the reconstructed image to generate a blended image.

  • Patent number: 10380002
    Abstract: An instrumentation analysis system processes data streams by executing instructions specified using a data stream language program. A user interface allows users to specify data stream language programs. The user interface presents widgets to the user to specify various components of a data stream language program including a filter expression, an analytical function representing an aggregation or transformation, and so on. The user interface allows users to specify an expression based on results of previously specified data stream language programs. The instrumentation analysis system processes the data stream language programs specified by the user to generate a set of result data streams and plots the result data streams, for example, on a screen of a client device.

  • Publication number: 20190238490
    Abstract: One or more systems and/or techniques for generating a content item from content within a content area are described herein. A first boundary and a second boundary may be defined for a content area based upon a first user input and a second user input, such as swipe gestures. A content item may be generated based upon content within the content area. In an example, a beginning boundary designator may be displayed for the first boundary and an ending boundary designator may be displayed for the second boundary in response to one or more swipe gestures of a user interface. In an example, the content item may be stitched to a second content item to create a stitched content item.

  • Patent number: 9982068
    Abstract: The invention provides a redox flow battery comprising a microporous or nanoporous size-exclusion membrane, wherein one cell of the battery contains a redox-active polymer dissolved in the non-aqueous solvent or a redox-active colloidal particle dispersed in the non-aqueous solvent. The redox flow battery provides enhanced ionic conductivity across the electrolyte separator and reduced redox-active species crossover, thereby improving the performance and enabling widespread utilization. Redox active poly(vinylbenzyl ethylviologen) (RAPs) and redox active colloidal particles (RACs) were prepared and were found to be highly effective redox species. Controlled potential bulk electrolysis indicates that 94-99% of the nominal charge on different RAPs is accessible and the electrolysis products are stable upon cycling. The high concentration attainable (>2.
