    • A detection arrangement and method for detecting the operation of electronic apparatus in the vicinity of a detection arrangement is provided. A first plurality of RF frequencies at which a receiver of the detection arrangement receives noise or interference signals in the absence of the operational electronic apparatus is identified. A second plurality of RF frequencies at which emissions from said operative electronic apparatus occur is identified. Each of a third plurality of RF frequencies is listened at, the third plurality of RF frequencies being determined on the basis of said second plurality of RF frequencies but excluding RF frequencies in said first plurality of RF frequencies. The operation of electronic apparatus is detected by reception of a predetermined signal on at least one RF frequency from said third plurality of RF frequencies.
    • 提供一种用于检测检测装置附近的电子设备的操作的检测装置和方法。 识别检测装置的接收器在不存在操作电子设备的情况下接收噪声或干扰信号的第一多个RF频率。 识别来自所述可操作电子设备的发射的第二多个RF频率。 在第三多个RF频率中的每一个被收听,第三多个RF频率基于所述第二多个RF频率而被确定,但是排除所述第一多个RF频率中的RF频率。 通过从所述第三多个RF频率接收来自至少一个RF频率的预定信号来检测电子设备的操作。

    • An optical display system includes an image generator providing discrete anamorphic picture elements to form an image, with each picture element spatially compressed along only a short dimension. A fiber optic array magnifier extends from the image generator and includes optical fibers dimensioned for optically coupling to each discrete anamorphic picture element. An output face of the array magnifier is bias-cut for magnifying the image along the short dimension. A light redirecting structure includes layered arcuate waveguide slabs optically coupled to the array magnifier with each of the arcuate waveguide slabs optically coupled to the array magnifier. A screen is integrally formed with the light redirecting structure and includes tapered slab waveguide portions positioned between light absorbing material having a saw tooth styled edge for providing multiple scattering and thus multiple absorption of ambient light incident upon the screen.
    • 光学显示系统包括图像发生器,其提供离散的变形图像元素以形成图像,每个图像元素仅沿着短尺寸空间压缩。 光纤阵列放大镜从图像发生器延伸并且包括尺寸适合于光耦合到每个离散变形像素的光纤。 阵列放大镜的输出面是偏置切割的,用于沿着短尺寸放大图像。 光重定向结构包括光学地耦合到阵列放大器的分层弓形波导板,其中每个弓形波导板与光学耦合到阵列放大镜。 屏幕与光重定向结构一体地形成,并且包括定位在具有锯齿风格边缘的光吸收材料之间的锥形平板波导部分,用于提供多个散射并因此多次吸收入射在屏幕上的环境光。
