    • Thermal wake proximate to an optical element of a telescope may be reduced. Signal(s) related to respective temperatures of support struts supporting the optical element may be generated. The respective temperatures of the support struts may be determined based on the signal(s). Individual support struts may be heated based on the respective temperatures of the support struts. Heating a given support strut may cause the given support strut to thermally expand. Individual support struts may be at least partially enclosed with corresponding shrouds. Airspaces may be disposed between individual support struts and the corresponding shrouds. Heat emitted in the airspaces by the support struts may be ejected away from the optical element to prevent a thermal wake from reaching a volume proximate to the optical element.
    • 靠近望远镜的光学元件的散热可以减小。 可以产生与支撑光学元件的支撑支柱的相应温度有关的信号。 支撑支柱的相应温度可以基于信号来确定。 可以基于支撑支柱的相应温度来加热单独的支撑支柱。 加热给定的支撑支柱可能导致给定的支撑支柱热膨胀。 单独的支撑支柱可以至少部分地与相应的护罩封闭。 空间可以设置在各个支撑支柱和相应的护罩之间。 通过支撑支柱在空间中发射的热可以从光学元件喷出,以防止热的尾迹到达靠近光学元件的体积。

    • A method and system for generating a workflow graph from empirical data of a process are described. A processing system obtains data corresponding to multiple instances of a process, the process including a set of tasks, the data including information about order of occurrences of the tasks. The processing system analyzes the occurrences of the tasks to identify order constraints. The processing system partitions nodes representing tasks into subsets based upon the order constraints, wherein the subsets are sequence ordered with respect to each other such that all nodes associated with a given subset either precede or follow all nodes associated with another subset. The processing system partitions nodes representing tasks into subgroups, wherein each subgroup includes one or more nodes that occur without order constraints relative to nodes associated with other subgroups. A workflow graph representative of the process is constructed wherein nodes are connected by edges.
    • 描述了从过程的经验数据生成工作流图的方法和系统。 处理系统获得与进程的多个实例相对应的数据,所述处理包括一组任务,所述数据包括关于任务发生顺序的信息。 处理系统分析任务的出现以识别订单约束。 处理系统基于订单约束将表示任务的节点分割成子集,其中子集相对于彼此被序列排序,使得与给定子集相关联的所有节点在与另一子集相关联的所有节点之前或之后。 处理系统将表示任务的节点划分为子组,其中每个子组包括相对于与其他子组相关联的节点没有订单约束而发生的一个或多个节点。 构建表示该过程的工作流图,其中节点通过边缘连接。

    • An optical gun sight system for an M1A2 Abrams Main Battle Tank supported in a lower housing which may be attached to the fixed internal upper housing in the turret of the tank. An adapter plate is provided which has two sets of openings, one to align with the openings in the upper housing and the other to align with openings in the lower housing. An alignment mechanism allows for fine adjustment of the lower housing relative to the upper housing. Operating buttons, knobs and filter wheel are conveniently located on or beneath the front face of the lower housing. A thermal imaging system includes an objective lens for receiving an image of a target object, an eyepiece lens for viewing the image of the object, and a compensator lens movably located between the objective and eyepiece lenses for providing a thermal image of the object. The system includes a servo motor control system for controlling the position of the compensator lens based upon temperature, range and field of view to provide an accurate thermal image of the object.
    • 一个用于M1A2 Abrams主战坦克的光枪瞄准系统,其支撑在下壳体中,其可以附接到坦克炮塔中的固定内部上壳体。 设有适配器板,其具有两组开口,一组与上壳体中的开口对准,另一组与下壳体中的开口对准。 对准机构允许下壳体相对于上壳体的微调。 操作按钮,旋钮和滤光轮位于下壳体正面的正下方。 热成像系统包括用于接收目标物体的图像的物镜,用于观看物体的图像的目镜,以及可移动地位于物镜和目镜之间的补偿透镜,用于提供物体的热像。 该系统包括用于基于温度,范围和视场来控制补偿透镜的位置的伺服电动机控制系统,以提供对象的精确热图像。
