Supporting, Mounting, Enclosing Or Light Shielding Structure Patents (Class 359/477)
  • Patent number: 9311883
    Abstract: The technology provides embodiments for recalibration of outward facing cameras supported by a see-through, head mounted, mixed reality display system having a flexible portion between see-through displays for the eyes. Each outward facing camera has a fixed spatial relationship with a respective or corresponding see-through display positioned to be seen through by a respective eye. For front facing cameras, the fixed spatial relationship allows a predetermined mapping between positions on an image sensor of each camera and positions on the respective display. The mapping may be used to register a position of a virtual object to a position of a real object. A change in a first flexible spatial relationship between the outward facing cameras can be automatically detected. A second spatial relationship between the cameras is determined. A registration of a virtual object to a real object may be updated based on the second spatial relationship.

  • Publication number: 20090168167
    Abstract: A display device reduces the image quality degradations by suppressing the effect of the defective alignment regions caused by the spacers while minimizing the aperture ratio lowering, and prevents the image quality change dependent on the observation positions. The display device has a display panel and a lenticular lens. Each unit pixel of the display panel includes the sub-pixel for the left eye and the sub-pixel for the right eye. To keep the pair of substrates at a predetermined gap, spacers are arranged at predetermined positions in the gap. The spacers are stripe-shaped and extended along a direction perpendicular to the image separation axis of the lenticular lens. The spacers are equally overlapped with the sub-pixels for the left eye and those for the right eye. The spacers may be isolated for the respective unit pixels, or the first or second sub-pixels.

  • Patent number: 7488079
    Abstract: A shaped screen rotates through one or more projected images of two or more projectors operating simultaneously, resulting in a dynamic, kinetic image surface which may be viewed equally well from a plurality of angles, up to 360° horizontally. By utilizing at least two projectors, the resultant composite image on the rotating screen is not only optimally viewed from any angle, but it is also animated by the movement of the screen itself, as well as by any animation within the projected image.

  • Patent number: 7356211
    Abstract: A stereoscopic display device is provided. The stereoscopic display device includes an optical waveguide member and a first main surface and a second main surface. The first and second main surfaces face each other. A first light path changing member is provided on at least one of the first and second main surfaces, and is operative to change the path of light guided by the optical waveguide member. A second light path changing member is provided on at least one of the first and second main surfaces, and is operative to change the path of the light guided by the optical waveguide member. A reflector body is disposed so as to face the second main surface and reflects the light emitted from the second light path changing member to the first main surface.

  • Patent number: 7177080
    Abstract: A viewing arrangement includes an image generator having a single, two-sided display screen having a front and a back side which display a front image and a back image, respectively, of a translucent or transparent image generated by the image generator; two eyepieces suitable for viewing the front and back images via respective eyes of a person using the arrangement; and an optical imaging system which images and transmits the front image to one eye of the person using the arrangement via the first eyepiece, and the back image to another eye of the person using the arrangement via the second eyepiece. A corresponding method includes generating an image; processing the image with an optical imaging system into front and back images; displaying the front and back images on a two-sided display; and transmitting the front and back images to first and second eyepieces.

  • Patent number: 6873460
    Abstract: A retractable screen system suitable for portable, hand held computing and communication units joins a number of optical sheets to form a rollable, extendible and retractable projection sheet. The resulting folded optical system provides a lightweight, portable unit. Telescoping arms allow the screen to be extended and stowed quickly and easily. High screen resolution is afforded by multiple mechanisms that scan concurrently. Beam indexing of the screen permits the precise alignment via feedback, and an embodiment fit for military, command and control applications.

  • Patent number: 6641900
    Abstract: A multilayered polymer film includes a first set of optical layers and a second set of optical layers. The first set of optical layers is made from a polyester which is often birefringent. The polyesters of the first set of optical layers typically have a composition in which 70-100 mol % of the carboxylate subunits are first carboxylate subunits and 0-30 mol % are comonomer carboxylate subunits and 70 to 100 mol % of the glycol subunits are first glycol subunits and 0 to 30 mol % of the glycol subunits are comonomer glycol subunits, where at least 0.5 mol % of the combined carboxylate and glycol subunits are comonomer carboxylate or comonomer glycol subunits. The multilayered polymer film may be used to form, for example, a reflective polarizer or a mirror.
