  • Patent number: 10721419
    Abstract: A method for correcting perspective distortion includes acquiring a plurality of images of a given subject by at least one camera of a mobile device, wherein each of the images is taken using respective actual settings for the camera captured by at least one sensor of the mobile device. The method further includes processing the images and the respective actual settings for each of the images to synthesize a single image of the given subject, wherein the single image emulates using specified virtual settings for the camera. The method further comprises displaying the synthesized single image of the given subject to a user of the mobile device.

  • Patent number: 10714341
    Abstract: Lift-off methods for fabricating metal line patterns on a substrate are provided. For example, a method to fabricate a device includes forming a sacrificial layer on a substrate and forming a photoresist mask over the sacrificial layer, isotropically etching a portion of the sacrificial layer exposed through an opening of the photoresist mask to form an undercut region in the sacrificial layer below the photoresist mask, wherein the undercut region defines an overhang structure, and anisotropically etching a portion of the sacrificial layer exposed through the opening of the photoresist mask to form an opening through the sacrificial layer down to the substrate. Metallic material is deposited to cover the photoresist mask and to at least partially fill the opening formed in the sacrificial layer without coating the overhang structure with metallic material. The sacrificial layer is dissolved to lift-off the metallic material covering the photoresist mask.

  • Publication number: 20200174596
    Abstract: Devices, systems, computer-implemented methods, and computer program products that can facilitate estimating orientation and/or identity of an entity that touches a touch screen device are provided. According to an embodiment, a device can comprise a pixelated touch screen that provides a two-dimensional capacitance map in response to detection of one or more entities touching the pixelated touch screen. Capacitance data of the two-dimensional capacitance map is inversely proportional to a distance between fingers of the one or more entities and the pixelated touch screen. The device can further comprise a processor that applies an analytic method to the two-dimensional capacitance map to estimate orientation or identity of the one or more entities.
