Appeal No. 2001-0603
Application 09/028,063
determining the direction of arrival of a traveling spectrally
spread signal wavefront of measurable center-frequency
wavelength, comprising . . . means for taking the output of a
single element and shifting it in frequency by an amount fifHz,
and inverting its instantaneous envelope waveform, resulting in
an auxiliary modulation-wipeoff signal . . . means for
determining said direction of arrival from said detected phase
differences.” Thus, Appellant’s claim 17 recited an apparatus
for determining direction arrival of a traveling spectrally
spread signal wavefront of measurable center-frequency wavelength
wherein an output of a single element of array of signal-sensing
elements is shifted in frequency, and its instantaneous envelope
waveform is inverted.
For the same reasons we have pointed out above we fail to
find that Baghdady teaching of a method and apparatus for
distinguishing extraneous noise from a single spectrum line
signal would not have directed those skilled in the art to modify
Tong to obtain the claimed apparatus as recited in Appellant’s
claims 17 and 21.
In view of the foregoing, we will not sustain the rejection
