    • Pixel elements capable of imaging spatial intensity variations within themselves, and displays comprised of such elements, are described. The pixel elements include a resistance layer disposed between at least one set of electrodes. Over that resistance layer is a liquid crystal material. Over that liquid crystal material is a field electrode. In operation a voltage, whose components are referenced to the field electrode, is applied across the resistance layer. The resulting current flow induces a spatially varying electric field between the field electrode and the resistance layer. That spatially varying electric field results in a corresponding response by the liquid crystal layer which results in a spatially varying light transmission through the liquid crystal material. By varying the voltage across the resistance layer and/or the voltage applied to the field electrode varying amounts of light transmission can be achieved.

    • Sensor elements which are capable of sensing illumination edges with subpixel accuracy are described. The sensor elements include a plurality of conductive storage nodes and a plurality of collection electrodes which are in a low resistance, touching relationship with a first semiconductive material layer. A second semiconductive material layer is placed over the first such that the first and second semiconductive material layers and the storage nodes form light sensors. Near the first semiconductive layer is a gate electrode. When a first voltage is applied to the gate electrode the resistance of the first semiconductive material layer between the storage nodes and the conductive collection electrodes is high. Illumination which strikes the sensor element creates electron hole pairs which induce charges on the storage nodes. When a second voltage is applied to the gate electrode the resistance of the first semiconductive material layer between the storage nodes and the conductive collection electrodes becomes low. Charges which have accumulated onto the storage nodes can then easily flow to the conductive collection electrodes.

    • Bands of predetectors (92) detect the approach of lines of glyphs (12, 14) within an image being scanned. Linear lines or arrays of glyph detectors (116, 118, 120) are sampled in accordance with the detected approach of lines of glyphs. Each detector array includes a plurality of analog glyph detectors (20, 50) which respond to the presence of glyphs with a characteristic analog output. Preferably, the glyph detectors generate a corresponding analog output of a first polarity or other characteristic in response to glyphs of a first orientation and an output of a second polarity or characteristic in response to glyphs of a second orientation. The analog signals which are characteristic of the detection of a glyph are converted into binary 1's and 0's in accordance with the polarity or other characteristic of the signals. In this manner, glyphs are detected by analog detectors and the information encoded in the glyphs is directly output as a binary signal without computer analysis of the image.

    • An image detection and pixel processing system includes a plurality of detector elements for receiving an image. The detector elements are subdivided into a plurality of macrodetectors, with each macrodetector constituting four or more detector elements, and with each macrodetector providing information for determining both a total light intensity value within the macrodetector and a centroid of light intensity indicative of light intensity position within the macrodetector. An image processing assembly receives information from the plurality of macrodetectors, with the image processing assembly relating a pixel and its encompassed subpixel area to each corresponding macrodetector, and further determining the total light intensity within the pixel and the centroid of light intensity within the subpixel. The image processing assembly is capable of rendering each subpixel area as an edge when magnitude of the centroid of light intensity is greater than a predetermined threshold.

    • A variable fluid flow valve is disclosed. The valve can be batch fabricated in two dimensional valve arrays, with all valves in the array being controlled in parallel to achieve high flow rates without increasing response time. Typically, each valve includes a valve housing having an aperture plate defining an elongated aperture therethrough, and an opposing plate positioned in spaced apart relationship to the aperture plate. In one embodiment a flexible film or strip is attached at its first end to the aperture plate and at its second end to the opposing plate. In another embodiment of the invention, the flexible film is attached at only one end and is free to move at the other end. In both types of valves, valve action is provided by using electrodes to variably move the flexible film from an aperture blocking to an aperture non-blocking position. The flexible film may be moved in a continuously variable manner or a discretely variable manner, depending upon the electrode configuration. Binary valves in matrixes may also be used with the elongated opening.
    • 公开了一种可变流体流量阀。 该阀可以批量制造在二维阀阵列中,阵列中的所有阀并联控制以实现高流速而不增加响应时间。 通常,每个阀包括具有限定穿过其中的细长孔的孔板的阀壳体和与孔板间隔开的关系。 在一个实施例中,柔性膜或带在其第一端附接到孔板并且在其第二端处连接到相对的板。 在本发明的另一个实施例中,柔性膜仅在一端附接并在另一端自由移动。 在两种类型的阀中,通过使用电极来将柔性膜从孔径阻挡可变地移动到孔阻塞位置来提供阀动作。 取决于电极配置,柔性膜可以以连续可变的方式或离散地变化的方式移动。 基体中的二元阀也可以与细长的开口一起使用。
