    • A Digital Elevation Database is converted to a Polygon Database by creating square cells of varying sizes, starting with a minimum size cell. A center elevation point in the cell is used to form four three-dimensional triangles. The points within the cell are then tested against the flatness criteria. If the cell meets the flatness criteria it is expanded and tested again. This goes on until the cell fails the flatness criteria or a maximum specified cell size is reached. The cell parameters for the last trial cell meeting the flatness criteria or the maximum specified cell size are then entered into the polygon database. The points in the cell are then removed from the elevation database and the process starts over until all the points have been processed. In a second embodiment the procedure starts with a maximum size cell and the cell size is reduced until the cell meets the flatness criteria.
    • 数字高程数据库通过从最小大小的单元格开始,创建不同大小的方形单元格,将其转换为多边形数据库。 单元中的中心高程点用于形成四个三维三角形。 然后根据平坦度标准测试细胞内的点。 如果电池符合平坦度标准,则再次进行扩展和测试。 这一直持续到单元格失效的平坦度标准或达到最大指定的单元格大小。 然后将满足平坦度标准或最大规定单元格大小的最后一个试验单元的单元格参数输入到多边形数据库。 然后单元格中的点从高程数据库中删除,并且过程开始,直到所有点都被处理。 在第二实施例中,程序以最大尺寸的单元开始,并且单元尺寸减小,直到单元满足平坦度标准。

    • A driving simulator for a video game is disclosed. It includes an apparatus and method for moving the visual display of the dashboard relative to the visual display of the outside scene by horizontal scrolling when the car is being turned. A model processor calculates an acceleration vector acting on the drivers head based upon conditions affecting the vehicle such as acceleration during turns. This acceleration vector is scaled and converted to an integer from floating point. The integer value is then digitally low pass filtered to eliminate the graininess of the discrete nature of the process. Finally two routines are called which use the integer data to calculate where the dash, mirror and cab sidepost are to be displayed in the scene of the simulated environment displayed to the driver. Another routine is then called to load the appropriate data into the hardware which performs the scrolling.
    • 公开了一种用于视频游戏的驾驶模拟器。 它包括一种用于当汽车正在转动时通过水平滚动来相对于外部场景的视觉显示来移动仪表板的视觉显示的装置和方法。 模型处理器基于影响车辆的条件(如转弯时的加速度)来计算作用在驾驶员头部上的加速度矢量。 该加速度矢量被缩放并从浮点转换为整数。 然后对整数值进行数字低通滤波,以消除过程离散性质的粒度。 最后,调用两个使用整数数据的例程来计算在显示给驱动程序的模拟环境的场景中显示破折号,镜像和cab侧面的位置。 然后调用另一个例程将适当的数据加载到执行滚动的硬件中。

    • An internal processing capability is added to a computer memory by adding a small processor, a small amount of processor RAM memory, a small amount of non-volatile memory, and some logic. During wafer testing the internal processor system allows the memory to be tested at full speed and substantially simultaneously with the testing of other memories on the wafer. At any stage after packaging, the part can be tested by having the host processor read the non-volatile memory, determine what test program to use, load it into the RAM memory, and run the Self-Test program. The internal processor system also allows additional functions such as data searching, data moving, and graphics primitives to be performed entirely within the memory.

    • A system for sensing aircraft and other objects uses bistatic radar with spread-spectrum signals transmitted from remotely located sources such as aircraft flying at very high altitudes or from a satellite constellation. A bistatic spread spectrum radar system using a satellite constellation can be integrated with a communications system and/or with a system using long baseline radar interferometry to validate the digital terrain elevation database. The reliability and safety of TCAS and ADS-B are improved by using the signals transmitted from a TCAS or ADS-B unit as a radar transmitter with a receiver used to receive reflections. Aircraft and other objects using spread spectrum radar are detected by using two separate receiving systems. Cross-Correlation between the outputs of the two receiving systems reveals whether a noise signal is produced by the receiving systems themselves or is coming from the outside.
    • 用于感测飞机和其他物体的系统使用双基地雷达,其具有从远程位置的源传输的扩频信号,例如飞行器在非常高的高度飞行或从卫星星座飞行。 使用卫星星座的双稳态扩频雷达系统可以与通信系统和/或与使用长基线雷达干涉测量的系统集成以验证数字地形高程数据库。 通过使用从TCAS或ADS-B单元发送的信号作为具有用于接收反射的接收机的雷达发射机,提高了TCAS和ADS-B的可靠性和安全性。 使用扩频雷达的飞机和其他物体通过使用两个独立的接收系统进行检测。 两个接收系统的输出之间的交叉相关性揭示了噪声信号是由接收系统本身产生的还是来自外部的。
