Title: Network echo canceller
Inventor: SIH GILBERT C
IPC: G10L19/012
Filed: 1993-09-24
Abstract: An echo canceller and method for cancelling in a return channel signal an echoed receive channel signal where the echoed receive channel signal is combined by an echo channel with an input return channel signal. The echo canceller has a first filter which generates first filter coefficients, generates a first echo estimate signal with the first filter coefficients, and updates the first filter coefficients in response to a first filter control signal. A first summer subtracts the first echo estimate signal from a combined return channel and echo receive channel signal to generate a first echo residual signal. A second filter generates second filter coefficients, generates a second echo estimate signal with the second filter coefficients, and updates the second filter coefficients in response to a second filter control signal. A second summer subtracts the second echo estimate signal from the combined signal to generate a second echo residual signal, and provides upon the return channel the second echo residual signal. A control unit determines from the receive channel signal, the combined signal, and the first and second echo residual signals, one of a plurality of control states wherein a first control state is indicative of a receive channel signal above a first predetermined energy level, wherein when the control unit is in the first control state it generates the first control signal and generates the second control signal when at least one of a first energy ratio of the first echo residual signal and the combined signal and a second energy ratio of the second echo residual signal and the combined signal exceed a predetermined level. <IMAGE>

Abstract: A substantially rigid thermoplastic pipe, manufactured in a flattened and folded form so as to have a memory in this condition is stored in such form, heated to make it pliable for installation and positioned in an existing pipe. The new pipe is rounded by placing heated fluid in the passages along the folds of the pipe while its leading end is restricted. The leading end may be restricted by an end clamp which enables a hot fluid to pass completely through the pipe and thus heat its full length, or by an inflatable plug. Alternatively, an inflatable plug may be propelled to the leading end of the new pipe after its insertion and then fully inflated to block such end and thereby enable full rounding and expansion of the remainder of the new pipe.
