  • Publication number: 20200284963
    Abstract: An optical element includes an optical surface configured to receive light at a predetermined wavelength in a range from about 400 nm to about 1000 nm. The optical surface is defined by a vertical axis and a horizontal axis defining four Cartesian quadrants sequentially numbered in a counter-clockwise direction. A first longitudinal section of the optical surface is centered on the vertical axis and a second longitudinal section of the optical surface is centered on the horizontal axis. The first and second longitudinal section each extend across opposite edges of the optical surface and have a same substantially uniform retardance for substantially normally incident light. The optical element includes four discrete retarder sections. Each retarder section is disposed on a respective Cartesian quadrant of the optical surface and has a retardance difference from the substantially uniform retardance of the optical surface that is greater than zero.

  • Publication number: 20200029443
    Abstract: Multilayer articles that include electrical circuits are prepared by the adhesive transfer of electrical circuit elements to the surface of an adhesive. A number of different methodologies are used, with all of the methodologies including the use of simple layers of circuit-forming material on a releasing substrate and structuring to generate circuit elements which can be transferred to an adhesive surface. In some methodologies, a structured releasing substrate is used to selectively transfer circuit-forming material, either from protrusions on the releasing substrate or from depressions on the releasing substrate. In other methodologies, an unstructured releasing substrate is used and either embossed to form a structured releasing substrate or contacted with a structured adhesive layer to selectively transfer circuit-forming material.

  • Publication number: 20190360135
    Abstract: A web of nonwoven fabric suitable for, e.g., the loop portion of a hook-and-loop fastening system. The method for making this material relies on differential shrinkage of different layers to cause the loops to self-form. The method is robust and simpler than that previously used for similar constructions.
