  • Patent number: 12222539
    Abstract: A light guide spacer is provided for maintaining sufficient spacing between a diffuser and a light emitting surface of a light guide. The light guide spacer maintaining spacing between the diffuser and the light guide has the exemplary benefit of providing more uniform light emission from the light emitting surface and protecting the light emitting surface (e.g., from physical damage, cleaning solutions, etc.). The light guide spacer may span the length of the light guide and diffuser, maintaining spacing along a length of the light guide, providing mounting of the diffuser and light guide, and maintaining a position of the diffuser, such that it protects the light emitting surface of the light guide.

  • Patent number: 11656519
    Abstract: A liquid crystal device that is flexible and includes a cholesteric liquid crystal material erased by flexing. Totally free of electronics and electrically conductive electrodes, the liquid crystal device takes advantage of a reverse mode effect observed in cholesteric liquid crystals whereby pressure applied to the device changes a reflective texture to a transmissive texture to create an image. The image is erased and the device reinitialized by flexing to create reflective texture surroundings.
