C. Brad Brocwell 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).

  • Patent number: 11426066
    Abstract: A selection for an acuity test chart is received in distributed Web content that correlates to a distance between an end user and a display of the test chart. A selection also is received of a trio of lines of different widths in a set of lines defining one of twelve radially equidistant radii of equal length extending from a common vertex in an astigmatism clock chart. An astigmatism fan chart also is generated and presented in the Web content utilizing three of the trio of lines in the selection and including twelve repeating sequences of three radially equidistant radii of different widths corresponding to the different widths of the utilized three of the trio of lines. One of the radii is selected and a prescription computed including the visual acuity value, a cylinder value deriving from the selected trio, and an axis value deriving from the selected radii.

  • Publication number: 20200394704
    Abstract: A method, system and computer program product for remote frame styling. The method includes acquiring an image of a face of a person wearing a pair of reference eyeglasses, loading eyeglass prescription data for the person and computing fitting measurements for the person from the image. The method further includes querying a data store of eyeglass frames according to the computed fitting measurements to filter the eyeglass frames to only those of the eyeglass frames meeting the computed fitting measurements and further filtering the filtered eyeglass frames to a subset of eyeglass frames validated against the prescription data. The method yet further includes retrieving an image of a selected one of the further filtered eyeglass frames, overlaying the retrieved image of the selected one of the further filtered eyeglass frames over the acquired image of the face of the person to produce a composite image, and displaying the composite image.
