  • Patent number: 10773490
    Abstract: Surface-modified adhesives may be prepared by contacting an adhesive layer to an at least partially discontinuous layer on a releasing substrate and removing the adhesive layer such that at least a portion of the at least partially discontinuous layer adheres to the adhesive surface. The modified adhesive surface remains an adhesive surface. The modified adhesive layer can be used to prepare adhesive articles, including articles containing multiple surface-modified adhesive layers.

  • 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: 20200011797
    Abstract: A system is provided for performing metal trace analysis on a liquid sample. A sample holder holds an analysis substrate that includes a reference region and at least one test region. An ultraviolet (UV) light source emits ultraviolet light illuminating the liquid sample. An optical sensor detects radiation emanating from the liquid sample and converting the detected radiation into an electrical signal. A microcontroller processes the electrical signal. An external interface transmits the processed electrical signal to an external device. The analysis substrate is configured for manual movement by a user. A tracking system detects a sample scanning location for the metal trace analysis, and includes a light source, other than the UV light source, and another optical sensor. The other optical sensor detects light emitted by the light source.
