    • A PC board actuator that emulates a muscle fiber includes a first pressure source, a second pressure source lower than the first source, at least one expansion chamber alternately communicating with the first and second pressure sources, first and second valves mounted with the PC board that opens and closes the chamber with respect to the first and second pressure sources, and an actuator member interacting with the expansion chamber to apply a force to the object. The actuator is preferably formed using planar batch technology and the valves preferably comprise electrically controllable flap valves mounted on the PC board. Alternatively, the actuator includes antagonistically arranged expansion chambers that operatively apply reciprocating forces to the object. In other embodiments, the actuator includes plural expansion chambers arranged in series or in parallel in order to increase the overall extent of attainable displacement or to amplify the force generated by the actuator.

    • 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。

    • 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.
    • 预先检测器带(92)检测正在扫描的图像内的字形线(12,14)的接近。 根据检测到的字形线的方法对线性线或字形检测器(116,118,120)的阵列进行采样。 每个检测器阵列包括多个模拟字形检测器(20,50),其响应于具有特征模拟输出的字形的存在。 优选地,字形检测器响应于第一取向的字形和响应于第二取向的字形的第二极性或特性的输出而产生第一极性或其他特性的相应模拟输出。 根据信号的极性或其他特性,将检测字形的特征的模拟信号转换为二进制1和0。 以这种方式,通过模拟检测器检测字形,并且在字形中编码的信息直接作为二进制信号输出,而不对图像进行计算机分析。
