Appeal No. 97-0425
Application 08/330,335
amendment after final rejection was filed on August 28, 1995
and was entered by the examiner. This amendment cancelled
claims 31-33. Therefore, this appeal is directed to the
rejection of claims 1-30 which constitute all the claims
remaining in the application.
The disclosed invention pertains to a method and
apparatus for evaluating signals of a Doppler signal
transceiver in order to monitor the relative positions and
velocities of two vehicles which are travelling one behind the
other.
Representative claim 17 is reproduced as follows:
17. An apparatus for producing velocity signals in
accordance with the relative velocity between a first and
second unit, while both are moving relative to a surface,
comprising a Doppler module which is attached to the first
unit and targets the second unit, the Doppler module having
means for transmitting an unmodulated continuous wave signal,
for receiving the continuous wave signal returning from the
targeted second unit with Doppler shift and for providing
phase related Doppler signals from the Doppler module, a
signal processor for receiving Doppler signals from the
Doppler module, wherein the signal processor contains Fourier
transform means for producing and storing the frequency
spectrum of the Doppler signals without intermediate frequency
processing, and means for supplying a signal dependent upon
the velocity of the first unit moving relative to the surface,
and wherein the signal processor further contains direction-
sensitive means for producing output signals indicative of
whether the targeted second unit approaches or moves away from
the first unit.
