Appeal No. 1998-0743
Application 08/214,169
Regarding independent claims 1, 5 and 13, we do not agree with
the examiner’s position at page 14 of the answer that,
Since Kimball teaches the single
sideband modulated signal (the sum of the
modulated carrier 250Hz) which is applied
to a transducer (115) to produce a
vibratory signal; it therefore would have
been obvious to one skilled in the art to
provide means for forming a single sideband
amplitude modulate frequency signal, as
taught by Kimball, in the Lenhard system
for transmitting the sound signals to the
human body in a desired range.
As noted by appellants in their supplemental brief, there is
no reason why one of ordinary skill in the art would have been
motivated to transmit signals in a desired range. Lenhardt
does not pertain to a communication system wherein modulated
carrier signals are transmitted from a transmitter to a
receiver over the airwaves or through wires. Lenhardt
discloses a hearing aid wherein the vibrator which applies
vibrations to the skull for bone conduction must provide such
vibrations at a frequency in the supersonic range. There is
no need to reduce bandwidth in Lenhardt’s apparatus since it
is not a communication system, and thus does not operated
under communication channel bandwidth limitations because it
