    • An illuminated sign apparatus comprised of a reflector with dedicated cavities. Each letter and, optionally, background area, comprises a shaped cavity, illuminated indirectly by a plurality of near-point sources such as light-emitting diodes located in the center of the cavity, either on a separate perpendicular circuit board or on a central projection formed in the bottom of the cavity, with the light emitted by the sources pointed outwards. In another embodiment, the letter cavities and background are illuminated by parallel boards along the top, bottom, and (optionally) middle of the letter cavities, with the light sources directed along the axes of the letter strokes. In another embodiment, the light sources in the center of the cavity are electroluminescent and ultraviolet emitting, and the cavity can be coated with a UV activated flourescent coating which is activated by the EL light source. The light is evenly reflected upward toward the viewer, giving the illusion of a solid letter or background. The cavities may be filled with a transparent substance.
    • 一种照明标志装置,由具有专用空腔的反射器组成。 每个字母和任选的背景区域包括成形的腔,其被多个近点源间接照射,例如位于空腔中心的发光二极管,或者在单独的垂直电路板上或在中心突起 形成在腔的底部,由光源发出的光指向外侧。 在另一个实施例中,字母腔和背景沿着字母腔的顶部,底部和(任选地)中间的平行板照射,光源沿着字母笔划的轴线指向。 在另一个实施例中,空腔中心的光源是电致发光和紫外线发射的,并且可以用由EL光源激活的UV活化的荧光涂层涂覆空腔。 灯光均匀地向观察者反射,给出了一个坚实的字母或背景的错觉。 空腔可以填充有透明物质。

    • An illuminated sign apparatus comprised of a reflector with dedicated cavities which are formed by having the perimeter walls of each cavity conform precisely to each individual area of the sign desiring illumination, typically alphabetic characters and the background area they create. The bottom walls of these cavities will project towards the viewers eye parabolically. The midpoint of the cavity, when viewed in cross section, is to be slightly less in height than that of the cavity-defining perimeter walls. The perimeter walls have point source lights such as light emitting diodes (LEDs) distributed along their surface. These cavities may be filled in with transparent substance, fully encapsulating the LEDs thereby eliminating any reflective air space and facilitating light diffusion. The light sources may be provided with circuitry allowing unique powering to each of the individual cavities, resulting in the possibility of a variety of different display effects.
    • 由具有专用空腔的反射器组成的照明标志装置,其通过使每个空腔的周边壁精确地符合要求照明的符号的每个单独区域,通常为字母字符及其创建的背景区域而形成。 这些空腔的底壁将抛物线地朝观察者眼睛投射。 当从横截面观察时,空腔的中点的高度要比空腔限定的周边壁略高。 周边墙壁具有点光源,例如沿其表面分布的发光二极管(LED)。 这些空腔可以用透明物质填充,完全封装LED,从而消除任何反射空气空间并促进光扩散。 光源可以设置有允许对每个单个空腔独特供电的电路,导致各种不同显示效果的可能性。

    • A method that improves compensation for hard cuts and/or vertical motion effects in the conversion of 2D images to 3D images, displays 2D images to one eye and computed images to the other eye. Generating the computed images includes using an approximation variable that represents some relationship between the 2D images, such as the speed of motion across two images. Compensating for the hard cut or vertical motion effect includes temporarily setting the approximation variable to a value that makes the left and right eye images more similar (if identical, displaying a 2D image). The approximation variable can be pre-set to a value based on the speed of motion in a scene to be displayed. A method of displaying images in either 2D or 3D may include converting 3D images to 2D images by displaying images computed from images intended for either the left eye or the right eye.
    • 将2D图像转换为3D图像时,可以提高对硬切割和/或垂直运动效果的补偿的方法,将2D图像显示给一只眼睛,并将另一只眼睛计算图像。 生成计算的图像包括使用表示2D图像之间的某些关系的近似变量,诸如跨两幅图像的运动速度。 补偿硬切割或垂直运动效果包括将近似变量临时设置为使得左眼图像和右眼图像更相似的值(如果相同,显示2D图像)。 近似变量可以根据要显示的场景中的运动速度预先设定为一个值。 以2D或3D显示图像的方法可以包括通过显示从用于左眼或右眼的图像计算出的图像来将3D图像转换成2D图像。
