    • A beam deflection scanner performs reciprocating deflection scanning with an ion beam or a charged particle beam to thereby periodically change a beam trajectory and comprises a pair of scanning electrodes installed so as to be opposed to each other with the beam trajectory interposed therebetween and a pair of correction electrodes installed in a direction perpendicular to an opposing direction of the pair of scanning electrodes, with the beam trajectory interposed therebetween, and extending along a beam traveling axis. Positive and negative potentials are alternately applied to the pair of scanning electrodes, while a correction voltage is constantly applied to the pair of correction electrodes. A correction electric field produced by the pair of correction electrodes is exerted on the ion beam or the charged particle beam passing between the pair of scanning electrodes at the time of switching between the positive and negative potentials.

    • A navigation-satellite receiver support data network comprises a server connected to the Internet to provide initialization information to clients for faster cold starts. The server includes a GPS receiver that provides for tracking of a constellation of navigation satellites. When a client is started cold, time and frequency are initially unknown to it. Test messages are sent back and forth over the Internet and a path delay time is computed from the average of the quickest transit times. This yields the offset time between the server's time system and the client's time system. The server sends current time information to the client, and the computed path delay is added. The client can then compute correct time from the server and path delay information, and thereby select much sooner which satellites are correct to search.
    • 导航卫星接收机支持数据网络包括连接到因特网的服务器,以向客户端提供初始化信息以用于更快的冷启动。 服务器包括GPS接收器,用于跟踪导航卫星的星座。 当客户开始冷静时,时间和频率最初是未知的。 测试消息通过互联网来回发送,并且路径延迟时间是从最快的传输时间的平均值来计算的。 这产生了服务器的时间系统和客户端的时间系统之间的偏移时间。 服务器向客户端发送当前时间信息,并添加计算出的路径延迟。 然后,客户端可以从服务器和路径延迟信息计算正确的时间,从而选择更早的哪个卫星正确搜索。
