    Abstract: An input device having a plurality of low-visibility sensor electrodes and method for fabricating the same are provided. In one embodiment, an input device includes a plurality of sensor electrodes disposed over a display device. A first sensor electrode of the plurality of sensor electrodes includes a conductive mesh having a first periodicity defined by intersections of conductive traces forming the mesh. A terminal portion of one of the conductive traces terminating at an edge of the first sensor electrode has an orientation that is different than an orientation of a corresponding portion of the mesh defining the first periodicity. An end of the terminal portion proximate the edge laying over a subpixel has the same color as a subpixel of the display device which the end would lay over if the end had the same orientation as the corresponding portion of the mesh defining the first periodicity.

    Abstract: Disclosed are systems and methods for imaging an object. For example, an optical sensor for imaging an input object, comprises: a sensor substrate comprising detector pixels; a scattering layer; a cover layer including a sensing surface, wherein the scattering layer is disposed between the sensor substrate and the cover layer; and, a light source. The optical sensor is configured to: illuminate the light source causing light beams to emanate from the light source to produce an effect of a point light source at the scattering layer; and acquire image data, from one or more detector pixels, of an input object in contact with the sensing surface, wherein the image data corresponds to light from the light source that is reflected at the sensing surface of the cover layer.

    Abstract: An input device having a plurality of low-visibility sensor electrodes and method for fabricating the same are provided. In one example, an input device includes a display device having an array of pixels and a plurality of sensor electrodes disposed on a viewing side of the display device. At least a first sensor electrode of the plurality of sensor electrodes includes a plurality of spaced apart conductive traces forming a conductive mesh, wherein mesh having a first periodicity defined by intersections of the conductive traces forming the mesh. A terminal portion of one of the conductive traces terminates at an edge of the first sensor electrode and has an attached light occluding element. The attached light occluding element is disposed over a subpixel having the same color as a subpixel which an intersecting trace would lay over when the intersection occurs in an interior region of the sensor electrode.

    Abstract: A biometric input system includes: a biometric sensor, configured to generate a biometric image comprising features of an input biometric object; and a processing system, configured to receive the biometric image, generate a feature map from the biometric image, perform a distance transform on the feature map, and determine an attribute of the biometric image from the distance transform. The processing system is further configured to compare the determined attribute of the biometric image with corresponding attributes of enrolled biometric images, and, based on the comparison, to eliminate enrolled biometric images from a matching process for the biometric image, wherein the matching process is performed after the elimination and comprises comparison of the biometric image to remaining enrolled biometric images based on one or more attributes of the biometric image other than the determined attribute.
