  • Laminated input devices
    Patent number: 10571624
    Abstract: The description relates to laminated input devices, such as keyboards. One example can include a laminated light-distribution assembly and a key assembly adhered in light receiving relation to the laminated light-distribution assembly as a laminated input device having a neutral axis in the light-distribution assembly.
    Type: Grant

  • Control of polarization and diffractive artifact resolution in retro-imaging systems
    Patent number: 9798154
    Abstract: Polarization state in retro-reflective arrays may be controlled throughout the optical path of a retro-reflective retro-imaging setup to enhance system efficiency. A polarization beam splitter layer and a retarder layer placed in front of the retro-reflector array may be oriented such that polarized light is used as source, source input light is efficiently reflected at the polarization beam splitter layer toward the retro-reflective layer, and polarization is converted to circular upon first pass through retarder layer. The polarization may also be oriented at or near 45° with respect to input polarization state, light may be retro-reflected and reconverged at the retro-reflective layer, and converted to linear polarization state. The light may then be rotated about 90° with respect to input linear state, and/or passed through the polarization beam splitter layer upon second pass to form the reconvergent image.
