    • A battery charging method (300) determines a current at which to start charging the battery which provides the capability for faster higher current sourcing capability. A start current(Istart)is determined based on the battery's cut off voltage, steady state voltage, and characteristic impedance (314). This start current is then compared and adjusted based on the rated power supply current for the power supply (316, 318) and rated charge current for the battery (320, 322). The adjusted current is then applied to the battery (324) at the beginning of the charge sequence to provide faster higher current sourcing capability.
    • 电池充电方法(300)确定开始对电池充电的电流,其提供更快的较高电流源能力的能力。 基于电池的截止电压,稳态电压和特性阻抗确定启动电流(Istart)(314)。 然后基于电源(316,318)的额定电源电流和电池(320,322)的额定充电电流来比较和调整该启动电流。 然后在电荷序列开始时将调整后的电流施加到电池(324),以提供更快的更高的电流源。

    • A system for monitoring guiding and controlling an unmanned, unteathered flight vehicle, generally assumed to be moving through the earth's atmosphere at a high rate of speed. The system is comprised of on-board positional receiver and processing means coupled to a transceiver capable of combining such positional information with additional data relative to the health and status of the flight vehicle and transmitting the same to a ground station of compatible and simplified design. A preferred positional determination means is to utilize a form for GPS signal thereby affording one the opportunity to include appropriate processing software or additional componentry if necessary for base station purposes and thereby provide a relatively inexpensive system having a low probability of detection for intercept that simultaneously yields vastly improved operating performance characteristics over the mere translation of received GPS signals to down-link or to remote stations as known in the prior art.
    • 一种用于监控指导和控制无人驾驶飞机的系统,通常假定它们以高速率通过地球大气层。 该系统包括车载位置接收器和耦合到收发器的处理装置,该收发器能够将这种位置信息与相对于飞行器车辆的健康状况和状态的附加数据组合,并将其发送到兼容和简化设计的地面站。 优选的位置确定装置是利用一种用于GPS信号的形式,从而提供一个机会,以便在基站目的需要时包括适当的处理软件或附加组件,从而提供一种相对便宜的系统,其具有低的拦截概率,同时产生 如现有技术中已知的,将接收到的GPS信号简单地转换为下行链路或远程站的操作性能特征大大改善。
