    • This disclosure presents a method of canceling inductance-dominated crosstalk using a capacitive coupling circuit; it also presents a method of calibrating, selecting and programming a capacitance value used for coupling, so as to add a derivative of each aggressor signal to each victim signal, and thereby negate crosstalk that would otherwise be seen by a given receiver. In the context of a multiple-line bus, cross-coupling circuits may be used between each pair of “nearest neighbors,” with values calibrated and used for each particular transmitter-receiver pair. Embodiments are also presented which address crosstalk induced between lines that are not nearest neighbors, such as, for example, for use in a differential signaling system.
    • 本公开提供了一种使用电容耦合电路消除以电感为主的串扰的方法; 它还提出了一种用于校准,选择和编程用于耦合的电容值的方法,以便将每个攻击者信号的导数加到每个受害者信号上,从而否定给定接收机否则将会看到的串扰。 在多线总线的上下文中,可以在每对“最近邻”之间使用交叉耦合电路,其中校准并用于每个特定的发射机 - 接收机对的值。 还提出了解决在不是最近邻的线路之间引起的串扰的实施例,例如用于差分信号系统中的串扰。

    • In order to synchronise video and audio signals, a video test signal and an audio test signal are generated at the transmitting end of a transmission link, and transmitted over the link. The video test signal has first and second active picture periods of contrasting states. The audio test signal has first and second periods of contrasting states. As generated, the video and audio test signals have a predetermined timing relationship—for example, their changes of respective states may be coincident in time. At the receiving end of the link, the video and audio test signals as received are detected, and any difference of timing between the video and audio test signals is derived from their changes of respective states, measured and displayed, including an indication of whether the video signal arrived before the audio signal or vice-versa. Additionally or alternatively, such a measurement signal can be used in a control loop to compensate for the delay and automatically re-synchronise the audio and video signals. The system is particularly suitable for transmission of video and audio over separate paths of a link—e.g. respectively over satellite and terrestrial paths.
    • 为了同步视频和音频信号,在传输链路的发送端生成视频测试信号和音频测试信号,并通过链路发送。 视频测试信号具有对比状态的第一和第二活动图像周期。 音频测试信号具有第一和第二周期的对比状态。 如产生的,视频和音频测试信号具有预定的定时关系,例如,它们各自状态的变化可能在时间上是一致的。 在链路的接收端,检测到接收到的视频和音频测试信号,并且视频和音频测试信号之间的任何时间差异都来源于其测量和显示的各自状态的变化,包括是否 视频信号在音频信号之前到达,反之亦然。 另外或替代地,这样的测量信号可以用在控制环路中以补偿延迟并自动重新同步音频和视频信号。 该系统特别适用于通过链路的单独路径传输视频和音频 - 例如。 分别通过卫星和地面路径。

    • The chassis connects adjacent flotation members each having supports projecting therefrom for attaching to the chassis. The chassis includes a pair of beams having opposite ends and sides with an end flange affixed to the ends of the beams. A plate is affixed to one of the opposite sides of the beams and has a length greater than the beams to form extension surfaces at each end. The extension surfaces are connected to the supports on a first plane and the end flanges are connected to the supports on another plane, preferably perpendicular to the first plane and vertical to the ground. The beams are preferably I-beams having a web and opposing extending sides perpendicular to the web. The top side is longer than the web and other side so as to form a tine which is received in a recess in the end flanges. Further, preferably the end flanges project beyond the end flanges and the opposing sides of the I-beam to form a border area having a plurality of apertures adapted to receive fasteners, such as nuts and bolts. The extension surfaces also include a plurality of apertures adapted to receive fasteners.
