    • An apparatus is provided for automatically reducing glare produced from a spatial scene by reducing the intensity of light rays propagating from points in the three-dimensional spatial scene towards an optical element having a field of view. Further, an apparatus is provided that automatically reduces interfering illumination produced from an illumination source by reducing the intensity of light rays propagating from the illumination source towards a sensor having a field of view of radio communication. Both apparatus include an electro-optical element having an optically transparent surface including a plurality of pixels through which the field of view of the optical element or the sensor passes. Each pixel has a controllable light transmittance for selectively reducing the intensity of incident light rays propagating from one or more points from the illumination source, through the pixel, then towards the sensor or optical element. An image acquisition device is included for acquiring one or more images of the illumination source within the field of view of the sensor or optical element. A processor is also included for processing the acquired images and determining at which pixels the light transmittance is to be actively controlled in order to reduce the intensity of incident light rays before reaching the sensor or optical element. A control is also provided for actively controlling the light transmittance of the determined pixels so that after incident light rays propagate through the determined pixels, the incident light rays propagate towards the sensor or optical element with reduced intensity.
    • 提供一种装置,用于通过减少从三维空间场景中的点传播到具有视场的光学元件的光线的强度来自动减少从空间场景产生的眩光。 此外,提供一种装置,其通过将从照明源传播的光线的强度减小到具有无线电通信的视场的传感器,自动减少从照明源产生的干扰照明。 两种装置都包括具有光学透明表面的电光元件,该光学透明表面包括多个像素,光学元件或传感器的视场通过该像素通过。 每个像素具有可控的光透射率,用于选择性地降低从照明源的一个或多个点传播的入射光的强度,穿过像素,然后朝向传感器或光学元件。 包括用于在传感器或光学元件的视野内获取照明源的一个或多个图像的图像采集装置。 还包括处理器以处理所获取的图像,并且确定哪个像素将要主动地控制透光率,以便在到达传感器或光学元件之前降低入射光线的强度。 还提供控制以主动地控制所确定的像素的透光率,使得在入射光线传播通过所确定的像素之后,入射光线以降低的强度向传感器或光学元件传播。

    • A system and method for converting an analog voltage signal to a digital representation at high speeds, known as an analog to digital converter (A/D converter), is provided. The invention teaches an N-bit A/D converter, made by N superconducting, preferably HTC, transmission lines. The N lines are arranged adjacently and in parallel with each other. On each line 2 N-1 JJs are imbedded in series. The JJs form a matrix over the configuration of the N superconducting transmission lines in such a manner that across the lines the JJs give N digit binary numbers, while in the length direction these N digit binary numbers fall in numerical order. A scanning electron beam is made to impinge on this arrangement. The beam is scanned across the lines at a high frequency, while it is deflected by the applied voltage signal along the direction of the lines. The beam generates a voltage step on any one of the N lines on condition of hitting any one of the JJs. In this manner upon each cross-scanning of the beam, an N-bit step voltage pattern is generated on the lines. This pattern is the direct digital readout of the input voltage signal.

    • 提供了一种用于将模拟电压信号以高速转换为数字表示的系统和方法,被称为模数转换器(A / D转换器)。 本发明教导了由N超导(优选HTC)传输线制成的N位A / D转换器。 N行相互并排设置。 在每条线上,2个N-1串联嵌入JJ。 JJ以这样的方式在N个超导传输线的配置上形成矩阵,使得跨越线路,JJ给出N个数字二进制数,而在长度方向上,这些N位二进制数按数字顺序落下。 使扫描电子束撞击这种布置。 光束以高频扫描线,同时沿着线的方向被施加的电压信号偏转。 在击中任何一个JJ的条件下,光束在N条线的任何一条上产生电压阶跃。 以这种方式在每次交叉扫描光束时,在线上产生N位步进电压模式。 该模式是输入电压信号的直接数字读出。
