    • Bands of predetectors (112, 116a, 116b, 116c, 118a, 118b, 118c, 120a, 120b, 120c) detect the approach of lines of glyphs within an image being scanned. Linear lines or arrays (110) of glyph detectors are sampled in accordance with the detected approach of lines of glyphs. Each detector array (110) includes a plurality of analog glyph detectors 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.

    • A method and apparatus are disclosed for transporting electrically charged particles suspended in a fluid, such as ions or the like, through the fluid, in a transport direction by means of a traveling electrostatic surface wave. The apparatus includes an array of transport electrodes (54) to which a source of A.C. multi-phase potential is applied to create a stable and controllable particle transport system in which the charged particles have a compound motion comprising a generally cyclical movement and drift movement through the fluid, in the transport direction. The locus of charged particle movement is maintained above the surface of the electrode array (54).

    • A method and apparatus which solve the problem of poor density and definition of an image formed by an ion current (20) projected from an ionographic print head (10), caused by electric field crosstalk between adjacent modulation electrodes (22) in the head (10). By applying a partial modulation voltage (V M ') to the adjacent modulation electrodes (22), the density of an individual pixel charge is increased and the pixel charge is "addressed" or deflected to a position on a receptor surface (26) more precisely than the pitch dimension between modulation electrodes (22). A data processor (46) intercepts printing driver commands (44) and constructs therefrom values of partial modulation voltage (V M ') by means of an algorithm making deliberate use of the crosstalk phenomenon. The algorithm is pre-defined with respect to image- dependent modulation voltage states and implemented as programmed software or firmware. The partial modulation voltage (V M ') is applied to correlated modulation electrodes (22) in response to the printing driver commands (44), by a controller (50) using modified printing commands (48) to produce a corrected image.
    • 一种解决由离子印刷头(10)突出的离子电流(20)形成的图像的不良密度和定义的问题的方法和装置,其由头部中的相邻调制电极(22)之间的电场串扰引起 10)。 通过对相邻的调制电极(22)施加部分调制电压(VM'),单个像素电荷的密度增加,并且像素电荷被“寻址”或更精确地偏转到接收器表面(26)上的位置 而不是调制电极(22)之间的间距尺寸。 数据处理器(46)通过使故意使用串扰现象的算法截取打印驱动程序命令(44)并从其构建部分调制电压(VM')的值。 该算法相对于图像相关的调制电压状态是预定义的,并且被实现为编程的软件或固件。 响应于打印驱动器命令(44),通过使用修改的打印命令(48)的控制器(50)将部分调制电压(VM')应用于相关调制电极(22)以产生校正图像。
