  • Patent number: 9400930
    Abstract: Embodiments disclosed obtain a plurality of measurement sets from a plurality of sensors in conjunction with the capture of a sequence of exterior and interior images of a structure while traversing locations in and around the structure. Each measurement set may be associated with at least one image. An external structural envelope of the structure is determined from exterior images of the structure and the corresponding outdoor trajectory of a UE. The position and orientation of the structure and the structural envelope is determined in absolute coordinates. Further, an indoor map of the structure in absolute coordinates may be obtained based on interior images of the structure, a structural envelope in absolute coordinates, and measurements associated with the indoor trajectory of the UE during traversal of the indoor area to capture the interior images.

  • Patent number: 9341483
    Abstract: Systems, apparatus and methods disclosed herein facilitate mobile station (MS) location determination using MS captured images of known points of interest (POIs). In some embodiments, each POI is associated with a corresponding visibility map comprising a set of grid points, and a subset of the POIs may be identified from the MS captured images by matching the MS captured images of each POI in the subset with corresponding stored images. A cumulative grid point weight for a plurality of grid points in the visibility maps associated with the POIs in the subset may be computed. The cumulative grid point weight for each grid point represents the probability that the MS is located at that grid point. The location of the MS may be estimated based on the cumulative grid point weights of the plurality of grid points.

The microfluidic devices comprise a fluid delivery channel and an array of wells wherein the fluid delivery channel delivery fluid into the wells in a serpentine arrangement. In some embodiments, the fluid delivery channel is directly above the array of wells. In other embodiments, the fluid delivery channel is offset from the array of wells so that side channels branching from the fluid delivery channel delivers fluid into the wells. The well of the microfluidic device comprises a gas-permeable membrane that forms the floor, well, or at least a portion of the floor or wall of the well. In preferred embodiments, the well is cylindrical.

  • Publication number: 20160087188
    Abstract: A sensing device is provided for acquiring a surface image of an object. The sensing device includes a protective layer, a conductive material layer under the protective layer, a first conductive film layer under the conductive material layer, a sensing layer under the first conductive film layer and a substrate under the sensing layer. When a surface of the object is pressed on the protective layer, a sensing signal is transmitted from the sensing layer to the surface of the object and a reflecting signal reflected from the surface of the object is received by the sensing layer. Then, a current signal corresponding to the reflecting signal is transmitted from the substrate to a central processing unit through the first conductive film layer. Consequently, the current signal is converted into the surface image of the object by the central processing unit.
