  • PERMEABLE SURFACE COVERING UNITS AND PERMEABLE SURFACE COVERING
    Publication number: 20170167086
    Abstract: A permeable surface covering unit comprises a top surface, a bottom surface and at least two pairs of sides. A cavity is formed in the unit from the top surface to the bottom surface, and has side walls. The cavity may be a side cavity between units and/or a core cavity within the unit. An undercut is provided in the cavity. Pervious material plugs fill the cavity and extend into the undercut. Thereby the plug is locked into the cavity like a rivet and resists being dislodged by mechanical or hydraulic forces.

  • SYSTEMS AND METHODS FOR AUTHENTICATING A USER BASED ON CAPTURED IMAGE DATA
    Publication number: 20160335511
    Abstract: Systems and methods are provided for authenticating a user of a computing device. The system comprises one or more memory devices storing instructions, and one or more processors configured to execute the instructions to provide, to a computing device associated with a user, an indication of a prescribed authentication parameter. The system also receives image data including an image of the user of the computing device captured using an image sensor of the computing device. The system determines an identity of the user based on an analysis of the received image data, determines whether the received image data includes a feature corresponding to the prescribed authentication parameter, and authenticates the user based at least in part on whether the received image data includes the feature corresponding to the prescribed authentication parameter.
