  • Patent number: 11263229
    Abstract: Systems and methods are disclosed for efficiently detecting alert states within unstructured event data. Alert states are illustratively defined as occurring when a threshold number of journey instances are present within the unstructured event data, each journey instance representing a series of events within the event data representing steps within a pre-defined journey. Detecting journey instances within unstructured event data can require significant computational resources, and thus attempting to detect alert states directly from unstructured event data can lead to inefficiencies. Embodiments of this disclosure enable a structured data set of journey instances to be generated from unstructured event data, and for the structured data set to be evaluated based on criteria of multiple alert states. By utilizing a single structured data set to support evaluation based on multiple alert states, detecting alert states from unstructured event data is rendered more efficient.

  • Patent number: 11175795
    Abstract: A method for dynamically displaying digital content, graphical user interface and a system thereof are provided. The graphical user interface displays multiple points of interest (POI) indicative of links of digital contents in a non-uniform arrangement. On a browsing page, the main POIs can be represented by thumbnails of associated digital contents on the interface. A user can browse the POIs and select one of the POIs via a touch-sensitive means, so as to play the digital contents. While selecting the POI, the POI becomes a center where the other POIs move toward that forms a converging animation effect. Afterwards, the digital contents associated to the selected POI are played sequentially on a playback page. The thumbnail of the POI is refreshed since some digital contents associated to the POI have been played when closing the playback page and returning to the browsing page.

  • Patent number: 11109781
    Abstract: Various embodiments of the invention provide systems and methods for low-cost, low-power Array Waveguide Grating (AWG)-based miniaturized Raman spectroscopy for use in non-invasive glucose monitoring systems, such as in wearable devices that require no replenishment of chemicals or enzymes. The AWG may be manufactured using VLSI processing technology, which significantly reduces manufacturing cost and replaces holographic grating as the dispersive component of light. In embodiments, the AWG is integrated with a number of PIN photodiode detectors on a substrate to further reduce cost and signal loss. In embodiments, a prism-coupling method eliminates alignment problems associated with traditional approaches that utilize fiber-coupling methods.

  • Patent number: 11103167
    Abstract: Presented are systems and methods that perform noninvasive glucose monitoring using mid-infrared self-emission of the human body that acts as a background radiation emitter. Various embodiments accomplish this by taking advantage of the guided-mode resonance (GMR) effect in a number of bandpass filters that are constructed as an array of coplanar filters. The filter array acts as a spectral separator that uses a grating layer and a thin film waveguide to form reflection and transmission filters for particular wavelengths. Unlike, common multi-layer optical filter designs that utilize numerous individual optical filters, a novel GMR filter design comprises an array of filters that may be fabricated from CMOS-compatible materials using only a few thin film and grating layers to filter light. Advantageously, this reduces manufacturing cost and allows for simultaneous monitoring of a number of wavelengths of the glucose spectrum.
