    摘要： A computer-controlled robot cutting system for making angled or beveled cuts along a preselected path in a workpiece having a generally planar cutting surface. A cutting knife, such as a high-intensity fluid jet, is pivotably mounted in a support frame having two pairs of arcuate guides disposed at right angles to each other for motor-driven rotation of the cutting knife about orthogonal axes. The centers of curvature of both guides lie on a critical plane containing a pivot point about which the cutting knife pivots. An opposing workpiece gantry with horizontal and vertical slides for motor-driven translation of the workpiece along two axes also includes means for holding the workpiece such that its surface to be cut faces the cutting knife and lies in the critical plane. The workpiece is thus translated to define the cutting path on the obverse surface, while the cutting knife is pivoted to define the entry angle of the cut along the cutting path. Four motion controllers under computer control coordinate the motors driving each axis of rotation or translation. Because the obverse cutting surface of the workpiece is maintained in the critical plane containing the pivot point, pivoting of the knife does not change its entry point in the cutting surface, thereby simplifying motion control algorithms. Furthermore, because the cutting knife is pivoted and the workpiece is translated, the relatively massive gearing and movable frame structures are distributed between the cutting knife section and the workpiece gantry, lowering the inertia and enabling the use of lighter-duty motors.

    摘要翻译： 一种计算机控制的机器人切割系统，用于沿着具有大致平面切割表面的工件中的预选路径进行倾斜或斜切切口。 诸如高强度流体射流的切割刀可枢转地安装在支撑框架中，该支撑框架具有彼此成直角设置的两对弓形导向器，用于切割刀绕正交轴线的电机驱动旋转。 两个导轨的曲率中心位于包含切割刀枢转的枢轴点的临界平面上。 具有水平和垂直滑动件的相对工件台架用于沿两个轴线的电机驱动平移工件还包括用于保持工件的装置，使得其被切割的表面面对切割刀并且位于临界平面中。 因此，工件被平移以在正面上限定切割路径，同时切割刀被枢转以限定切割沿着切割路径的入口角。 计算机控制下的四个运动控制器协调电机驱动每个旋转轴或平移轴。 因为工件的正面切削面保持在包含枢轴点的临界平面内，所以刀的转动不会改变其在切割表面中的入口点，从而简化运动控制算法。 此外，由于切割刀被枢转并且工件平移，所以相对较大的齿轮和可移动的框架结构分布在切割刀部分和工件台架之间，降低了惯性并且使得能够使用更轻的电动机。

    摘要： Systems and methods for illuminating an object surface with light at varying angles of incidence and for optically evaluating the object surface for features and defects, etc. are disclosed. In a specific implementation the systems and methods, the target object comprises a coin and the illumination and evaluation techniques are used to accurately objectively evaluate the numismatic quality of the coin and/or identify the coin. Central to the illumination and evaluation techniques is the ability to apply a uniform confined beam of light to the surface of the target object to be imaged. The confined angles of incidence of the beam of light includes a perpendicular component angle of incidence range and a parallel component angle of incidence range relative to the object surface. The component ranges are defined such a light beam illuminates the object surface from a well-defined direction. The direction and the extent of light beam illumination may be varied by redefining one or both of the component angle of incidence ranges. In addition to identifying features and defects of a coin surface, the illumination and evaluation techniques are capable of imaging the surface lustre of the coin.

    摘要： A video conferencing system and method which automatically determines the appropriate preset camera parameters corresponding to participants participating in the video conference. A camera zooms out or pans the video conference space and looks for participants based on their faces. When a participant is detected, the preset camera parameters for that participant are calculated for when the center of the participant is in the center of the camera's view. This is continued for all the participants in the room. The optimal position for each participant and corresponding camera parameters are determined based on cultural preferences. Updates in the presets can be made periodically by the camera zooming out or panning the room. Multiple cameras can be used to continually update the presets.

    摘要： The invention provides for the automation of a multiple camera system based upon the location of a target object in a displayed camera image. The preferred system provides a nearly continuous display of a figure as the figure moves about throughout multiple cameras' potential fields of view. When the figure approaches the bounds of a selected camera's field of view, the system determines which other camera's potential field of view contains the figure, and adjusts that other camera's actual field of view to contain the figure. When the figure is at the bounds of the selected camera's field of view, the system automatically selects the other camera. The system also contains predictive location determination algorithms. By assessing the movement of the figure, the system selects and adjusts the next camera based upon the predicted subsequent location of the figure.

    摘要： A system and method for assigning attributes to XML document nodes to facilitate their storage in relational databases and the subsequent retrieval and re-construction of pertinent nodes and fragments in original document order is provided. Since these queries are performed using relational database query engines, the speed of their execution is significantly faster than that using more exotic systems such as object-oriented databases. Furthermore, this method is portable across all vendor platforms, and so can be deployed at client sites without additional investments in database software.
