    • Commonly, a transient protection filter circuit is integrated between power sources and the circuits that follow to suppress voltage transients. Pre-existing transient protection filters are implemented such that when a transient is detected, transistors in the path become linear regulators. Instead, this invention uses bridge resistors to form a voltage divider to dissipate the extra power. The novelty of this invention is that it protects the load not by dissipating the extra power in front of the load as other transient protection filter circuits do, but by providing energy from the transient to the load through a resistor. This implementation solves the problem of thermal runaway that is commonly caused when transient voltages are filtered by dissipating power within the transistors in the path of the transient and the electric circuits after the transistors.
    • 通常,瞬态保护滤波器电路集成在电源和随后的电路之间以抑制电压瞬变。 实现了现有的瞬态保护滤波器,使得当检测到瞬态时,路径中的晶体管变为线性稳压器。 相反,本发明使用桥式电阻器来形成分压器以耗散额外功率。 本发明的新颖之处在于,其它瞬态保护滤波器电路不是通过消耗负载前面的额外功率来保护负载,而是通过电阻将瞬态能量提供给负载。 该实现解决了当瞬态电压通过在晶体管之后的瞬态路径和电路中的晶体管内消耗功率而被滤波时通常引起的热失控的问题。

    • One aspect of the invention provides an ingress apparatus comprising a signal processing apparatus for receiving an incoming data frame and locating the position of path overhead, and a monitoring apparatus arranged to extract information from the located path overhead. The ingress apparatus further includes an insertion apparatus for receiving, from the monitoring apparatus, information extracted from the path overhead of one or more signal path, and being further arranged to insert the extracted information into a respective data frame component which occupies a fixed position in a data frame. Thus, information which would normally occupy a non-fixed position in a data frame is moved to a fixed position. As a result, the information can subsequently be accessed without having to employ relatively complex apparatus for locating information which occupies a non-fixed position.
    • 本发明的一个方面提供了一种入口装置,包括用于接收输入数据帧并定位路径开销的位置的信号处理装置,以及被布置为从定位的路径开销提取信息的监视装置。 所述入口设备还包括插入设备,用于从所述监视设备接收从一个或多个信号路径的路径开销中提取的信息,并且还被布置为将提取的信息插入到占据固定位置的相应数据帧分量 一个数据框。 因此,通常在数据帧中占据非固定位置的信息被移动到固定位置。 结果,可以随后访问信息,而不必使用相对复杂的装置来定位占据非固定位置的信息。
