    • An multi-planar radiation emission system, preferably an X-ray biplanar transillumination system, for generating planar images of a subject from different perspectives includes a first X-ray source which emits first pulses of X-ray radiation toward a subject from a first direction at a first repetition rate, a first imaging device which detects the first pulses and generates a first image of the subject from a first perspective, a second X-ray source which emits second pulses of X-ray radiation toward the subject from a second direction at a second repetition rate which is different from the first repetition rate, wherein the first and second pulses are temporally interleaved and non-overlapping, and a second imaging device which detects the second pulses and generates a second image of the subject from a second perspective. The first and second images are preferably planar images which are "moving" images in the sense that information from successive pulses is used to periodically update the planar images on a display. The relative reduction of the pulse repetition rate of the pulses used to generate one of the two planar images advantageously reduces potentially harmful X-ray emissions and reduces the image processing required to generate the planar images without significantly sacrificing useful information, since one of the two images is generally referred to only occasionally to provide the observer with a three-dimensional perspective of the planar image of greater interest.
    • 用于从不同的角度产生被摄体的平面图像的多平面辐射发射系统,优选X射线双平面透照系统包括从第一方向向受试者发射X射线辐射的第一脉冲的第一X射线源 以第一重复率,第一成像装置,从第一角度检测第一脉冲并产生对象的第一图像;第二X射线源,从第二方向向对象发射X射线辐射的第二脉冲; 以与所述第一重复率不同的第二重复率,其中所述第一和第二脉冲在时间上交错和不重叠,以及第二成像装置,其从第二透视图检测所述第二脉冲并产生所述对象的第二图像 。 第一和第二图像优选地是在移动的图像中的平面图像,这意味着来自连续脉冲的信息被用于周期性地更新显示器上的平面图像。 用于产生两个平面图像之一的脉冲的脉冲重复率的相对减小有利地减少了潜在有害的X射线发射,并且减少了生成平面图像所需的图像处理,而不会显着地牺牲有用信息,因为两者之一 通常仅仅偶尔地将图像提供给观察者以感兴趣的平面图像的三维透视图。

    • In a system for controlling the motion of an industrial robot, a resultant translational velocity of a preselected point on the robot is calculated from a plurality of velocity values such as actual velocity values detected by sensors or target velocity values computed from a velocity reference value. Upon the exceeding of a predetermined maximum velocity by the calculated resultant velocity, all robot motion is terminated. Robot motion may also be stopped upon detecting an excessive difference between an actual angular velocity of one robot component and a respective desired or target angular velocity of that robot component, upon detecting an excessive translational acceleration of a predetermined point on the robot, or upon detecting a position of the robot part or point located more than a predetermined distance from a reference position.
