  • Publication number: 20200279102
    Abstract: A monitoring system or tracking system may include an input port and a controller in communication with the input port. The input port may receive video from one or more image capturing devices. The image capturing device is optionally part of the monitoring system and in some cases includes at least part of the controller. The controller may be configured to receive video via the input port and identify a subject within frames of the video relative to a background within the frames. Further, the controller may be configured to identify dimensions, posture, hand location, feet location, twisting position/angle, and/or other parameters of the identified subject in frames of the video and determine when the subject is performing a task. Based on the dimensions and/or other parameters identified or extracted from the video during the predetermined task, the controller may output via the output port assessment information.

  • Publication number: 20200183979
    Abstract: A method for providing a visual representation of data stored in a database may include generating a graphic user interface configured to receive inputs for constructing a hierarchical measure based on the data stored in the database. An indication to add, to the hierarchical measure, a first measure and a second measure may be received via the graphic user interface. In response to the indication, the hierarchical measure may be constructed to include, based on the first measure being added prior to the second measure, the first measure as a parent measure and the second measure as a child measure. A first value of the first measure may correspond to an aggregate of at least a second value of the second measure. The graphic user interface may be updated to provide a visual representation of the hierarchical measure. Related systems and articles of manufacture are also provided.

  • Patent number: 10661476
    Abstract: Novel methods of fabricating porous structures (e.g., nanostructures) and resulting structures are disclosed. The novel methods use precision optics to cure a slurry made from one or more powders mixed with photopolymers. Pore size control preferably is achieved by controlling the powder size and powder loading in the slurry. As the disclosed methods are based on optics to control the thickness preferably without any mechanical movements, extreme tight thickness tolerance, as well as control of the profile structure, may be achieved. The novel disclosed methods are highly-cost effective with shorter manufacturing cycle time compared to conventional methods. Moreover, a supporting substrate may not be required as the resultant structure made by the novel fabrication techniques disclosed herein has enough strength to be free-standing.
