Projection Screen Patents (Class 359/443)
  • Patent number: 10795252
    Abstract: A multichromic filtering coating is applied to a projector screen to pass to the projector screen substrate only those wavelengths produced by the projector, to accentuate selective wavelengths of light to be reflected by the screen. The screen can be a passive black substrate or an active grayscale screen such as e-ink paper, and un-reflected light reaches the screen which selectively tunes its grayscale to accentuate the brightness or darkness of the color video image being projected onto it.

  • Patent number: 9772549
    Abstract: An immersive display system is disclosed that includes screens configured to mitigate reduction in contrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least two screens and at least two projector systems. The screens have a multi-layered structure configured to selectively reflect light in a tailored polarization state. Adjacent screens can be configured to selectively reflect light in orthogonal polarization states. The projector systems can be configured to project video onto their respective screens with light in a suitable polarization state. The screens can be further configured to selectively reflect light within a plurality of tailored spectral bands, the spectral bands being different for respective screens.

  • Patent number: 9649545
    Abstract: A golf simulation system includes imaging devices capturing images of a projectile tracking region in front of a display surface from different vantages to detect a launched projectile traveling through the projectile tracking region towards the display surface. A projectile spin sensing unit captures images of a region at least partially overlapping with the projectile tracking region, and each captured image includes a projectile trail representing a travel path of the projectile. A processing stage receives data from the imaging devices and the projectile spin sensing unit and determines the three-dimensional positions, velocity, acceleration and spin of the projectile, and the three-dimensional positions, velocity, acceleration and spin are used by the processing stage to calculate a trajectory of the launched projectile into a presented golf scene.
