Patent DE-19812070-C1 (DE)
Title: Method of approximate speed measurement of railway vehicle
Inventor: JUNGKUNZ CLEMENS
IPC: B61F5/22
Filed: 1998-03-19
Granted: 1999-08-19
Abstract: The method involves measuring at least two signals (S1,S2) at least approximately describing identical geometric properties of the railway track at at least two mutually relatively movable separate positions on the vehicle. A time delayed version (S0) of the first signal is formed. The sum and difference of the weighted second signal and weighted, delayed first signal are formed using real coefficients and used to generate a control signal.  A speed correction signal (deltaV) is derived from the control signal (deltaS). The corrected speed signal is formed by adding the speed correction signal to a predefined speed signal (V0).

Title: Duplex data transmission method with quadrature amplitude modulation
Inventor: SCHENK HEINRICH
IPC: H04L5/14
Filed: 1998-09-28
Granted: 2000-07-06
Abstract: The method involves transmitting data with a quadrature amplitude modulation over two conductors in two channels transporting in opposite direction. An upper channel with a higher frequency range is transferred in the first direction, and a lower channel with a lower frequency range, not overlapping the higher frequency range, is transferred in the second direction.  Each of the channels transports two digital signals of a respective symbol frequency, namely a normal- and a quadrature data signal. A carrier signal is modulated on both sides with both digital data signals for transmitting. The received amplitude-modulated carrier signal is sampled with a first frequency for the upper channel and a second frequency for the lower channel. A pulse sequence resulting from the sampling is demodulated and low-pass filtered, and the resulting signal is sampled with the symbol frequency of the data signal for recovering both digital data signals.
