    Abstract: Pressure-sensing touch systems and methods are disclosed for sensing the occurrence of a touch event based on pressure applied at a touch location. The touch system includes a light-source system and a detector system operably adjacent respective input and output edges of a waveguide. Pressure at a touch location on the waveguide gives rise to a touch event causes the waveguide to bend or flex. The waveguide bending causes a change in the optical paths of light traveling by FTIR, causing the light distribution in the output light to change. The changes are detected and are used to determine whether a touch event occurred, as well as the time-evolution of the touch event. The changes in the output light can include polarization changes caused by birefringence induced in the waveguide by the applied pressure applied. Various detector configurations are disclosed for sensing the location and pressure of a touch event.

    Abstract: A diffraction element can be employed in a surface display unit to provide diffraction peaks in a manner that reduces or eliminates a screen door effect that is prevalent in pixelated displays that does not have sufficient pixel density. The parameters of the diffraction element can be selected such that the diffraction peaks provide appearance of a larger pixel area than a corresponding physical pixel size. For example, first order diffraction peaks can be placed at a distance of about ⅓ of a nearest subpixel-to-sub-pixel distance. The surface display unit can be employed for any image display application to enhance image quality. For example, a virtual reality headset to remove the screen door effect.

    Abstract: Lighting units and light fixtures incorporating lighting units having light-diffusing optical fiber are disclosed. Lighting units include a light source, at least one light-diffusing optical fiber optically coupled to the light source, and a support plate. The at least one light-diffusing optical fiber scatters light that is optically coupled into the at least one light-diffusing optical fiber from the light source. The support plate has a retention groove to which a portion of the at least one light-diffusing optical fiber is coupled. The support plate also includes a perimeter. A groove length of the retention groove is greater than the perimeter of the support plate.
