    • A system and method for providing notification when a state of a monitored system persists for a specified period of time utilizing distributed monitoring devices is disclosed. It is first detected, utilizing a monitoring device, that a monitored system is in a specified state. A timer within the monitoring device is initiated in response to detecting that the monitored system is in the specified state. The monitored system is monitored, utilizing the monitoring device, to determine whether the monitored system remains in the specified state. If the monitored system remains in the specified state for a specified period of time, notification is transmitted from the monitoring device to a client device via a network.
    • 公开了一种系统和方法,用于当所监视的系统的状态在指定的时间段内持续使用分布式监视设备时提供通知。 使用监控设备首先检测到被监控系统处于指定状态。 响应于检测到所监视的系统处于指定状态,启动监视设备内的计时器。 监视的系统利用监控设备进行监控,以确定被监控系统是否保持在指定状态。 如果受监视的系统在指定的时间段内保持指定状态,则通过网络将监控设备通知给客户端设备。

    • An active imaging system uses communication satellites to identify the location and physical attributes of a target. A transmitter emits a time-synchronized signal directed to a target. The transmitter radiates L-band RF signals. The transmitter can be positioned on an airborne or ground platform. A constellation of communication satellites receives and time stamps the time-synchronized signal reflected from the target to form an active image of the target. The constellation of communication satellites have multiple roles other than active imaging, such as providing voice and data communications. The time-synchronized signal reflected from the target can be received by multiple satellites within the constellation of communication satellites or by multiple antenna disposed on one satellite within the constellation of communication satellites.
    • 主动成像系统使用通信卫星来识别目标的位置和物理属性。 发射机发射指向目标的时间同步信号。 发射机辐射L波段RF信号。 变送器可以放置在机载或地面平台上。 通信卫星的星座接收并对从目标反射的时间同步信号进行时间戳,以形成目标的活动图像。 通信卫星的星座除了主动成像以外还具有多种角色,例如提供语音和数据通信。 从目标反射的时间同步信号可以由通信卫星星座内的多个卫星或通过设置在通信卫星星座内的一颗卫星上的多个天线接收。
