  • Publication number: 20190139179
    Abstract: Presented are systems and methods for 3D reconstruction from videos using an unsupervised learning framework for depth and normal estimation via edge-aware depth-normal consistency. In embodiments, this is accomplished by using a surface normal representation. Depths may be reconstructed in a single image by watching unlabeled videos. Depth-normal regularization constrains estimated depths to be compatible with predicted normals, thereby, yielding geometry-consistency and improving evaluation performance and training speed. In embodiments, a consistency term is solved by constructing depth-to-normal layer and normal-to-depth layers within a deep convolutional network (DCN). In embodiments, the depth-to-normal layer uses estimated depths to compute normal directions based on neighboring pixels. Given the estimated normals, the normal-to-depth layer may then output a regularized depth map. Both layers may be computed with awareness of edges within the image.

  • Patent number: 10279357
    Abstract: An aperture plate is manufactured by plating metal around a mask of resist columns having a desired size, pitch, and profile, which yields a wafer about 60 ?m thickness. This is approximately the full desired target aperture plate thickness. The plating is continued so that the metal overlies the top surfaces of the columns until the desired apertures are achieved. This needs only one masking/plating cycle to achieve the desired plate thickness. Also, the plate has passageways formed beneath the apertures, formed as an integral part of the method, by mask material removal. These are suitable for entrainment of aerosolized droplets exiting the apertures.

  • Patent number: 10284322
    Abstract: In some embodiments of the invention, OFDM symbols are transmitted as a plurality of clusters. A cluster includes a plurality of OFDM sub-carriers in frequency, over a plurality of OFDM symbol durations in time. Each cluster includes data as well as pilot information as a reference signal for channel estimation. In some embodiments, a plurality of clusters collectively occupy the available sub-carrier set in the frequency domain that is used for transmission. In some embodiments of the invention data and/or pilots are spread within each cluster using code division multiplexing (CDM). In some embodiments pilots and data are separated by distributing data on a particular number of the plurality of OFDM symbol durations and pilots on a remainder of the OFDM symbol durations. CDM spreading can be performed in time and/or frequency directions.
