    • The present invention relates to computing reachable areas given a first point. More specifically, the present invention relates to the computation of an intersection between a first surface and a second surface for determining a set of points that are reachable from a first point. Using the present invention, a user can determine either (1) a locus of target sites that can be struck by a ballistic projectile from a given launch site, or (2) a locus of launch sites that can be used to hit a given target site. The disclosed system and method employs graphics hardware to determine an intersection between a first surface defined by trajectory paths, and a second surface defined by terrain.
    • 本发明涉及计算可达到的第一点的区域。 更具体地,本发明涉及第一表面和第二表面之间的交叉点的计算,用于确定从第一点可到达的一组点。 使用本发明,用户可以确定(1)可以从给定发射场点被弹道射弹击中的目标位置的轨迹,或者(2)可用于击中给定目标的发射场所的轨迹 现场。 所公开的系统和方法使用图形硬件来确定由轨迹路径限定的第一表面和由地形限定的第二表面之间的交点。

    • An apparatus configured to obtain, process, and relay data to a user in a coherent and useful manner. An active fiducial is equipped with an interface for receiving and transmitting data. The fiducial may transmit its position using a satellite-based position sensing device such as a GPS. Active fiducials may also be equipped with battery power pack regenerated with solar cells. Similarly, the fiducials can be equipped with at least one video camera or other device having a focal plane array and a computer software system, configured to recognize shapes. The fiducials may also be equipped with inductive coils or other means for sensing metal containing compounds. The active fiducials may be equipped with a gas chromatograph. The active fiducials may use a variety of propulsion means including motor driven tracks, motor driven wheels, propellers, or other device or a combination of devices.

    • Described is a method for event localization within a distributed sensor array using a plurality of sensor nodes. The method includes an act of receiving a signal in at least one detecting node. The signal originates from an external disturbance and has a local signal such that the local signal reflects a relative proximity (i.e., between the detecting nodes) to the external disturbance. The method also includes acts of exchanging information regarding the signal between the detecting node and nearby nodes; and localizing the external disturbance based on its relative proximity. Through receiving a signal that reflects a relative proximity to the external disturbance and exchanging that information between nearby nodes, the sensor array localizes the external disturbance.
    • 描述了使用多个传感器节点在分布式传感器阵列内的事件定位的方法。 该方法包括在至少一个检测节点中接收信号的动作。 该信号源于外部干扰并且具有本地信号,使得本地信号反映相对接近(即,在检测节点之间)与外部干扰。 该方法还包括与检测节点和附近节点之间的信号交换信息的动作; 并根据其相对接近度来定位外部干扰。 通过接收反映与外部干扰相对接近的信号并在附近节点之间交换信息,传感器阵列定位外部干扰。
