    Abstract: A head-up display system includes a housing having an interior surface and defining a cavity configured for receiving a ray of light. The head-up display system also includes a lens disposed within the cavity and configured for reflecting the ray of light towards the interior surface. Further, the head-up display system includes a first cured film formed from a coating composition, disposed on the interior surface, and configured for absorbing a ray of light within the cavity. The head-up display system also includes a second deposited film formed by an ionized gas treatment of the first cured film. The second deposited film is configured for transmitting the ray of light to the first cured film to thereby minimize scatter of the ray of light within the cavity. A device including the head-up display system is also described.

    Abstract: An optical device that is disposed to manage light transmittance therethrough includes a multi-layer photochromic sheet that is composed of a first layer, a second layer, and a photochromic layer interposed therebetween. The photochromic layer is composed of a mixture of dichroic dye and photo-isomerizable material that are disposed in a liquid crystal host, and the first and second layers are each fabricated from a clear polymer.

    Abstract: A system for displaying information to an occupant of a vehicle includes a microphone, a camera for capturing images of an environment surrounding the vehicle, a display, and a controller in electrical communication with the microphone, the camera, and the display. The controller is programmed to receive a voice command from the occupant using the microphone, determine at least one characteristic of the requested object based on the voice command, capture an image of the environment using the camera, where the environment includes a relevant object, and to identify a location of the relevant object in the environment based at least in part on the image and the at least one characteristic of the requested object. The controller is further programmed to display a graphic based at least in part on the location of the relevant object in the environment using the display.

    Abstract: A head-up display system of a vehicle visually transmits information to eyes of a first occupant and eyes of a second occupant. The system includes an illumination device emitting first and second display lights having first and second polarizations, respectively. The system includes a windshield and a holographic panel including first and second layers. The display lights emit toward the holographic panel at an entrance angle relative to an axis normal to the holographic panel. The first layer diffracts the first display light having the first polarization in a first exit direction at a first exit angle relative to the axis toward the eyes of the first occupant. The second layer diffracts the second display light having the second polarization in a second exit direction at a second exit angle relative to the axis, and different than the first exit angle, toward the eyes of the second occupant.

    Abstract: A system for generating a centrally located floating three-dimensional image display for a plurality of passengers positioned within a vehicle includes a plurality of autostereoscopic three-dimensional displays, one autostereoscopic three-dimensional display individually associated with each one of the plurality of passengers, and a controller in communication with each of the plurality of autostereoscopic three-dimensional displays and adapted to cause each one of the plurality of autostereoscopic three-dimensional displays to display a three-dimensional image to the associated one of the plurality of passengers, wherein, each of the plurality of passengers perceives the three-dimensional image floating at a central location within the vehicle.

    Abstract: A head-up display for displaying graphics upon a windscreen of a vehicle includes a graphic projection module for generating images upon the windscreen of the vehicle, a user input device for receiving user-generated commands created by a user of the vehicle, and one or more controllers in electronic communication with the graphic projection module and the user input device. The controller executes instructions to instruct the graphic projection module to generate a luminance adjustment graphic, where the luminance adjustment graphic includes an adaptive color palette graphic including two or more colors. The controller receives, from the user input device, a user-generated luminance input indicating a change in a level of luminance in a selected color, where the change in the level of luminance in the selected color is selected by the user to discern differences between the two or more colors caused by a color vision deficiency.
