  • Patent number: 12291662
    Abstract: The present invention generally relates to photon upconversion nanocapsules for 3D printing and other applications. For example, one aspect is generally related to nanocapsules that contain an upconversion material. Light, such as laser light, focused on a region of liquid containing nanocapsules may be upconverted by the upconversion material to produce wavelengths sufficient to cause polymerization of a polymerizable entity to occur. However, in contrast, although other regions may receive some light, that light may not be of sufficient focus or intensity to be upconverted, and thus, the polymerizable entity in those regions would generally not polymerize. In such a fashion, the extent of polymerization can be controlled, for example, by controlling where light is applied to the liquid. The light could be focused at arbitrary regions within the liquid, thus allowing true 3D-printing to occur.

  • Patent number: 10552998
    Abstract: Embodiments of the present disclosure relate to a data analysis system configured to implement cross-application coordination between a chart creation tool and a data analysis workspace, in order to create one or more charts from customized sets of data points, synchronize chart manipulations between charts, and drill down into the metadata of data points in the created charts. The user uses the data analysis workspace to select, remove, or cherry-pick data items to be used to create a chart, which may be transmitted from the workspace to the chart creation tool as data points. In addition, the user may select the data points in the chart to retrieve one or more identifiers to be transmitted back to the workspace, where they are used to identify the data items associated with the data points, and retrieve the full metadata of the data items.

  • Patent number: 10018036
    Abstract: A system includes an optical fiber and an interrogator to provide source light to the optical fiber. The system also includes a receiver coupled to the optical fiber. The receiver includes at least one fiber optic coupler that receives backscattered light and that produces optical interferometry signals from the backscattered light. The receiver also includes photo-detectors that produce an electrical signal for each of said optical interferometry signals. The system also includes at least one digitizer that digitizes the electrical signals. The system also includes at least one processing unit that calculates I/Q data from the digitized electrical signals, corrects the I/Q data based on ellipse fitting, determines phase values based on the corrected I/Q data, and determines distributed sensing parameter values based on the phase values.

  • Publication number: 20160124250
    Abstract: Methods and apparatus using generating multiple color images in a single exposure. In one implementation, an imaging apparatus is provided that includes an image sensor array including a plurality of image sensor elements. The imaging apparatus also includes a dispersive element configured to rotate incident linearly polarized radiation by a rotation angle to produce rotated linearly polarized radiation having at least two polarization angles, wherein the rotation angle is determined based, at least in part, on a wavelength of the incident linearly polarized radiation. The imaging apparatus also includes a pixelated polarizing filter configured to receive the rotated linearly polarized radiation from the dispersive element and selectively pass the rotated linearly polarized radiation to the image sensor array, wherein the rotated linearly polarized radiation is selectively passed based on the polarization angle of the rotated linearly polarized radiation.
