    • A method for automatically estimating the spatial positions between cameras in a camera network utilizes unique identifying signals, such as RFID signals, transmitting between nearby cameras to estimate the relative distances or positions between cameras from received signal strength (RSS), time of arrival (TOA), or time difference of arrival (TDOA) measurements to thereby determine the neighboring relationship among the cameras. A discover-locate process can be used to discover, from the estimated relative distances, unknown cameras in the vicinity of at least three cameras at known locations. Absolute locations of the discovered unknown cameras can then be calculated using a geometric calculation. The discover-locate process can be cascaded throughout the network to discover and locate all unknown cameras automatically using previously discovered and located cameras. Such methods can be implemented in systems having cameras with transceivers integrated therein and a controller operably linked to the cameras.
    • 用于自动估计摄像机网络中的摄像机之间的空间位置的方法利用诸如RFID信号之类的唯一识别信号,在邻近摄像机之间传输,以从接收信号强度(RSS),到达时间(TOA)估计摄像机之间的相对距离或位置 )或到达时间差(TDOA)测量,从而确定相机之间的相邻关系。 可以使用发现定位过程从估计的相对距离中发现在已知位置处的至少三个相机附近的未知摄像机。 然后可以使用几何计算来计算发现的未知摄像机的绝对位置。 发现定位过程可以在整个网络中级联,以使用先前发现和定位的相机自动发现和定位所有未知摄像机。 这样的方法可以在具有集成有收发器的相机的系统中实现,以及可操作地连接到相机的控制器。

    • In accordance with the principles of the present invention, a beaconing device transmits a radio signal that can be detected by a plurality of wireless receivers positioned at various known locations. The receivers form nodes of a wireless network that further includes a control node with which the receivers can communicate. Each receiver that receives the signal from the beaconing device records the signal strength at which it receives the signal from the beaconing device and sends that information to the control node. The control node processes the signal strength information received from all of the receivers and uses it to estimate the location of the beaconing device. Particularly, the controller solves an optimization problem for the coordinates of the beaconing device by determining the set of coordinates for the beaconing device that minimizes the squared error over all of the receivers that receive the signal from the beaconing device between (1) the Euclidian distance between the known coordinates of the receiving device and the estimated coordinates of the beaconing device and (2) the estimated distance between the beaconing device and the particular receiver based on signal strength at that receiver.
    • 根据本发明的原理,信标设备发送无线电信号,该无线电信号可以被位于各种已知位置处的多个无线接收器检测到。 接收器形成无线网络的节点,该无线网络还包括接收器可以与之通信的控制节点。 接收来自信标装置的信号的每个接收器记录它从信标装置接收信号的信号强度,并将该信息发送给控制节点。 控制节点处理从所有接收机接收到的信号强度信息,并使用它来估计信标设备的位置。 特别地,控制器通过确定用于信标装置的坐标集来解决信标装置的坐标的优化问题,该坐标装置使得在(1)欧几里德距离之间接收来自信标装置的信号的所有接收器上的平方误差最小 在接收设备的已知坐标和信标设备的估计坐标之间,以及(2)基于该接收机处的信号强度估计信标设备和特定接收机之间的距离。

    • Systems and methods for controlling an engine using feedback from one or more sensors are disclosed. An illustrative control system for controlling a diesel engine may include one or more post-combustion sensors adapted to directly sense at least one constituent of exhaust gasses emitted from the exhaust manifold of the engine, and a state observer for estimating the internal state of the diesel engine based on feedback signals received from the post-combustion sensors and from subsequent use of the estimated state in a controller that sends the actuator setpoints. The post-combustion sensors can be configured to directly measure emissions such as oxides of nitrogen (NOx) and/or particulate matter (PM) within the exhaust stream, and provide such information to a state observer that, in turn, updates an internal dynamical state based on these measurements. In some cases, other sensors such as a torque load sensor, an in-cylinder pressure sensor, and/or a fuel composition sensor can be further used to update the internal state of the state space model, as needed. Using an estimated state from the state observer, a state feedback controller can compute and adjust various actuator setpoints from values that more accurately represent the true state of the system.
    • 公开了使用来自一个或多个传感器的反馈来控制发动机的系统和方法。 用于控制柴油发动机的示例性控制系统可以包括一个或多个后燃烧传感器,其适于直接感测从发动机的排气歧管发射的废气的至少一个成分,以及用于估计柴油内部状态的状态观测器 发动机基于从后燃传感器接收的反馈信号,以及随后在发送执行器设定点的控制器中使用估计状态。 后燃烧传感器可以被配置为直接测量排放物流中的氮氧化物(NOx)和/或颗粒物质(PM)的排放物,并将这些信息提供给状态观察者,反过来又更新内部动力学 状态基于这些测量。 在某些情况下,可以根据需要进一步使用诸如扭矩负载传感器,缸内压力传感器和/或燃料组成传感器的其它传感器来更新状态空间模型的内部状态。 使用来自状态观测器的估计状态,状态反馈控制器可以从更精确地表示系统的真实状态的值来计算和调整各种致动器设定点。
