    • A method for improving color-to-color registration in a printing device. The method includes printing a plurality of multi-color images, measuring the relative locations of a first portion of each multi-color image having a first color of each image and a second portion of each multi-color image having a second color of each image, for each image, comparing at least one difference between the first portion's location and the second portion's location with at least one desired difference between the first portion's location and the second portion's location to generate a list of positional errors, using a least square regression analysis of the list of positional errors to determine shift amounts required for placement of each first portion in subsequently generated images to within a desired degree of accuracy, and adjusting the placement of the first portion of each subsequently generated image by the determined shift amounts.
    • 一种用于改善打印设备中的颜色到颜色配准的方法。 该方法包括打印多个多色图像,测量具有每个图像的第一颜色的每个多色图像的第一部分的相对位置以及具有每个图像的第二颜色的每个多色图像的第二部分 对于每个图像,使用最小二乘回归分析将第一部分的位置和第二部分的位置之间的至少一个差异与第一部分的位置和第二部分的位置之间的至少一个期望的差异进行比较以生成位置错误的列表 确定位置误差列表,以确定将随后生成的图像中的每个第一部分放置在期望的精度范围内所需的移位量,以及将每个后续生成的图像的第一部分的位置调整所确定的移位量。

    • Side impact airbag system for a vehicle includes a side airbag arranged to deploy along a left or right side of the vehicle and an electronic crash sensor. The electronic crash sensor includes a housing, a mass arranged within the housing to be movable in a lateral direction relative to the housing in response to lateral accelerations of the housing, and a control mechanism for controlling deployment of the side airbag and which is responsive to the motion of the mass only in the lateral direction. The housing is mounted in such a position and a direction as to sense an impact into a side of the vehicle resulting in lateral acceleration of the housing. The electronic crash sensor may generate a signal representative of the movement of the mass.

    • An imaging device for producing multicolor images from image data containing data representing an image of a first color and an image of a second color to be registered relative to the image of the first color onto a substrate by transferring toner of the first and second colors to the substrate is provided. The imaging device includes a first imager, a second imager, a photoreceptor belt, a plurality of rollers mounted to a frame of the imaging device, an angular position sensor, an image data source and a controller. The plurality of rollers define a process path along which the photoreceptor belt is driven past the first and second imagers in a process direction. The plurality of rollers includes a drive roller that exhibits an eccentricity for which a formula relating angular position as a function of the phase angle of the drive roller to eccentricity is known. The angular position sensor detects the phase angle of the drive roller. The image data source generates image data that includes a line to be printed in the first color and in the second color. The controller is coupled to receive signals from the angular position sensor, ROS imager and image data source and is configured to drive the second imager to generate an optical output. The controller includes memory and a processor. The memory stores the formula relating angular position as a function of the phase angle of the drive roller to eccentricity. The processor calculates an appropriate time delay for starting the generation of the optical output of the second imager for printing the line to be printed in the first color and in the second color based on the time of the starting of the optical output by the ROS imager to print to print that line, the signal received from the angular position sensor, and the formula relating angular position as a function of the phase angle of the drive roller to eccentricity.
    • 一种成像装置,用于通过将第一颜色和第二种颜色的调色剂转印到基底上,从包含表示第一颜色和第二颜色的第二颜色的图像的数据的图像数据生成多色图像, 提供基板。 成像装置包括第一成像器,第二成像器,感光带,安装到成像装置的框架的多个辊,角位置传感器,图像数据源和控制器。 多个辊限定了沿着处理方向驱动感光带穿过第一和第二成像器的处理路径。 多个辊包括驱动辊,该驱动辊具有偏心度,对于该偏心,将与驱动辊的相位角相关的角位置与偏心度相关联的公式是已知的。 角位置传感器检测驱动辊的相位角。 图像数据源产生包括要以第一颜色和第二颜色打印的行的图像数据。 控制器被耦合以从角位置传感器,ROS成像器和图像数据源接收信号,并且被配置为驱动第二成像器以产生光输出。 控制器包括存储器和处理器。 存储器存储关于角位置作为驱动辊的相位角与偏心度的函数的公式。 处理器基于ROS成像器的光输出开始时间计算用于开始生成第二成像器的光输出的适当时间延迟,用于以第一颜色和第二颜色打印要打印的行 打印以打印该线,从角位置传感器接收的信号,以及将作为驱动辊的相位角的函数的角位置与偏心相关的公式。
