wherein said confined volume is characterized by cross--
sectional area as a function of distance from said opening in
said confined volume and said processor means provides as said
output signal an area signal that is characteristic of cross--
sectional area of said confined volume as a function of
distance from said opening in said confined volume." In
addition, claim 91 specifies in pertinent part the following
limitations: "processing said transduced parameters produced
in response to the incident wave, the reflected wave and any
reflected wave from a second end of the conduit to provide a
signal representative of an impulse response of the confined
volume and providing said output signal characteristic of said
confined volume geometry and providing an output signal
representative of said confined volume geometry, wherein said
confined volume is characterized by cross-sectional area as a
function of distance from said opening in said confined volume
and said output signal is representative of cross-sectional
area of said confined volume as a function of distance from
said opening in said confined volume." Giving claims 1-4, 6,
7, 10-12, 17, 18, 21, 22, 81-83, and 89-91 their broadest
reasonable interpretation, the limitations recite producing a
