William N. Pickeral has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Optical encoder with direction-dependent optical properties comprising a spindle having an array of surface features defining a concave contour along a first direction and a convex contour along a second direction
    Patent number: 11002572
    Abstract: Embodiments of the present disclosure provide an optical encoder for an electronic device. The optical encoder includes a spindle and an encoded pattern disposed around a circumference of the spindle. The encoded pattern may include one or more surface features that create a direction-dependent reflective region.
    Type: Grant
