Patents by Inventor Charles Ronald Mayfield

Charles Ronald Mayfield 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: 7236286
    Abstract: A device which simultaneously maximizes light reflectivity from one side of the device while maximizing light transmissivity from the opposite side of the device. The device is configured with distinct regions of transparency and reflectivity including a plurality of reflective structures. The structures are generally smaller towards a light transmitting side of the device and larger towards a light reflective side of the device.
    Type: Grant

  • Patent number: 6473220
    Abstract: A film which simultaneously maximizes light reflectivity from one side of the film while maximizing light transmissivity from the opposite side of the film. This is achieved by configuring the film with distinct regions of transparency and reflectivity where the extended boundary of the reflective region is shaped into a light funnel/pipe and where periodically placed discrete and/or extended/continuous shapes are created (such as extended triangular indentations, or discrete shapes such as a cone, a pyramid, or any polyhedron). The reflective region is composed of mirror-like material such as aluminum or silver, but may be a composite paste, a composite material, or multiple materials with different refractive indices or reflective qualities. In some embodiments, the reflective material is embedded in the transparent material such that the base of each shape is approximately parallel to and coincident with, or slightly recessed from the surface of the transparent material.
