    • A health monitoring system for a fuel cell stack using current fuel cell architecture to enable the electronic control unit (ECU) to continue to monitor the health of the fuel cell stack despite a component failure. The system uses an embedded measurement module (EMM) connected to a group of fuel cells in the fuel cell stack to monitor the health of that group of fuel cells. The EMM produces a pulse width modulation signal that is sent to the ECU. A total voltage value for the group of fuel cells is embedded into the calibration signal or end of frame sequence. The ECU uses an algorithm to determine a missing voltage of at least one fuel cell in the event of the component failure of that fuel cell by adding up the cumulative value for each fuel cell reporting their voltage and subtracting that value from the total voltage value found in the end of frame sequence.
    • 一种使用当前燃料电池结构的燃料电池堆的健康监测系统,以使电子控制单元(ECU)能够继续监测燃料电池堆的健康状况,尽管组件故障。 该系统使用连接到燃料电池堆中的一组燃料电池的嵌入式测量模块(EMM)来监测该组燃料电池的健康状况。 EMM产生发送到ECU的脉宽调制信号。 燃料电池组的总电压值嵌入到校准信号或帧序列的末尾。 ECU使用算法来确定在燃料电池组件故障的情况下至少一个燃料电池的缺失电压,通过相加每个报告其电压的燃料电池的累积值,并从发现的总电压值中减去该值 在帧序列的末尾。

    • Image frame length control apparatus and methods are disclosed which have particular utility in a printing or reproduction apparatus that writes one or more images on a transported photosensitive media such as a photoconducting drum or continuous-loop web. When an electronic writing system or optical exposure system is used to expose a driven media on a line-by-line basis, a variation in media thickness causes the latent image frame to be written with an inaccurate frame length. Consequently, a degraded print is produced.The latent image frame length is corrected during exposure, by adding or omitting one or more lines in the image frame. Alternatively, the exposure of an image is offet by an interval corresponding to one-half of the total length discrepancy between the uncorrected image frame length and the image frame length that would be written if the media surface speed was at a median level. The overall image length error is thereby reduced by half and distributed to the upper and lower extremities of the image frame. In another embodiment, the rotation rate of the media is increased or decreased when a respectively thin or thick portion of the media passes over the driving apparatus.The corrected image fames are written with greater fidelity to the original and, after development and transfer to a receiver, are particularly well-suited for use in forming an accurate multicolor reproduction.
    • 公开了图像帧长度控制装置和方法,其在打印或再现装置中具有特别的用途,该设备将一个或多个图像写入传送的光敏介质如光​​导滚筒或连续卷筒纸上。 当使用电子书写系统或光学曝光系统来逐行曝光从动介质时,介质厚度的变化使得潜像帧以不准确的帧长度被写入。 因此,产生劣化的打印。 在曝光期间,通过在图像帧中添加或省略一条或多条线来校正潜像帧长度。 或者,图像的曝光以对应于未校正的图像帧长度和如果介质表面速度处于中间水平时将被写入的图像帧长度之间的总长度差异的一半的间隔开始。 因此,整体图像长度误差减少了一半,并且分布到图像帧的上肢和下肢。 在另一个实施例中,当介质的分别薄或厚的部分通过驱动装置时,介质的旋转速率增加或减小。 校正后的图像信号以较高的保真度写入原稿,并且在显影和转印到接收器之后特别适用于形成准确的多色再现。

    • A tool for breaking a shaft includes two aligned tubular elements (20, 22), each having an end portion for receiving a contiguous length of the same shaft (2). Means are provided for locking each end portion against rotation relative to the shaft length received therein, and the elements are adapted for rotation relative to one another with the end portions so locked, to relatively twist the shaft lengths and shear the lengths at the interface between them. The element end portions will normally have juxtaposed faces, and it is preferred that the faces are moved towards each other during the relative rotation and as the shaft lengths are twisted relative to each other. This assists in achieving a substantially planar face at the fracture plane. A compressible washer may be disposed between the juxtaposed faces. This can stabilize the moving parts as the shaft is broken, although normally screw threads on the tubular elements will effect the movement of the element. towards each other, and this in itself may provide sufficient stability.
    • 用于断开轴的工具包括两个对准的管状元件(20,22),每个管状元件具有用于接收相同轴(2)的连续长度的端部。 提供装置用于锁定每个端部相对于容纳在其中的轴长度而防止旋转,并且元件适于相对于彼此旋转,端部被锁定,以相对扭转轴的长度并剪切在两者之间的界面处的长度 他们。 元件端部通常具有并列的面,并且优选的是,在相对旋转期间面彼此相对移动,并且随着轴长度相对于彼此扭曲。 这有助于在断裂面处实现基本平坦的面。 可压缩的垫圈可以设置在并列的面之间。 这可以在轴断裂时稳定运动部件,尽管管状元件上的螺纹通常会影响元件的移动。 并且这本身可以提供足够的稳定性。
