  • Publication number: 20160292921
    Abstract: A system (100), apparatus (110), and method (900) for displaying an image (880). Light (800) of varying intensities (820) can be incorporated into the same image (880). Such an image (880) can be comprised of more than one subframe (852), and each subframe can correspond to a different intensity region (860) within the image (880) generated through a different pulse (810) of light (800).

  • Publication number: 20160195721
    Abstract: A system (100), method (900), and apparatus (110) for displaying an image (880). The system (100) can use a curved mirror (420) in conjunction with a partially transparent plate (430) to project an image directly on the eyes (92) of a user (90). The curved mirror (420) and plate (430) combination can also be used for additional functions in a VRD visor apparatus (116) such as the ability to operate in a tracking mode (123) where the eyes (92) of the viewer (96) are tracked and the ability to operate in in augmentation mode (122) where the viewer (96) can see the displayed image (880) overlaying a view of their physical environment (650).

  • Publication number: 20160195718
    Abstract: A system (100), method (900), and apparatus (110) for displaying an image (880). The system (100) can utilize two or more diffusers (282) separated by a gap (290) to reduce the coherence of the light (800) used in the display of the image (880). The diffusers (282) can be diffuser film (283), diffuser paper (284), diffuser glass (285), diffuser coatings (286), or virtually any form of multi-textured surfaces (287). The gap (290) between two diffusers (282) can be an air gap (291), a glass gap (292), or some other form of space that is different from the diffusers (282) and at least semi-transparent. The system (100) can be embodied as a DLP system (141), an LCD system (142), an LCOS system (143), a system (100) utilizing virtually any type of display technology (140).

  • Publication number: 20160198133
    Abstract: A system (100), method (900), and apparatus (110) for displaying an image (880). To avoid the “rainbow effect” of conventional color displays, subframes (852) are illuminated using non-identical subframe illumination sequences (854).

  • Publication number: 20160195921
    Abstract: A media chair apparatus (200), system (100), and method (900). The media chair apparatus (200) includes a support assembly (400) that can be at least temporarily substantially fixed in an at least substantially fixed position while a seat assembly (300) rotates relative to the support assembly (400). A port (500) in the support assembly (400) can be used to interface with the operating environment (80) while a port (500) in the rotatable seat assembly (300) can be used to interface with a portable access device (150) used by the user (90) to access or otherwise enhance a media experience (800).

  • Publication number: 20150331246
    Abstract: An apparatus (110), system (100), and method (900) for displaying an image (880). Instead of using an expensive configuration of prisms (310) such as TIR prisms (311) or RTIR prisms (312) to direct light (800) to and from a DMD (324), a plate (340) with transmissive (374), reflective (372), and/or polarization (373) characteristics is used. The plate (340) can be implemented in a wide variety of different embodiments using a wide variety of different components and configurations.

  • Publication number: 20140253698
    Abstract: The ability of some people to perceive simulated stereoscopic images or even actual stereoscopic images can be enhanced by treating the two eyes differently. The disclosed system can enhance stereoscopic images by selectively modifying the incoming images using right/left differentiation filter. The system can also include the capability of filtering images using parameters that for which the right eye and left eye images are treated independently of each other.

  • Patent number: 7789371
    Abstract: A piezoelectric microvalve employs a valve element formed of hermetically sealed and opposed plates flexed together by a cross axis piezoelectric element. Large flow modulation with small piezoelectric actuator displacement is obtained by perimeter augmentation of the valve seat which dramatically increases the change in valve flow area for small deflections.
