Application No. 08/212,082
using the acoustic sensor as taught in Feldmaier for 2
sensing high frequency signals due to the deformation
of components associated with the vehicle during the
crash event and providing a high frequency signal
indicative of the deformation in order to combine a low
frequency accelerometer and a high frequency sensor to
provide a sensing system capable of giving early
indication of crash severity with addition of reliable
indication of crash direction and initial velocity
change. Thus, because of the motivation set forth
above, it would have been obvious to a person of
ordinary skill in the art at the time the invention was
made to combine the teachings of Feldmaier and Diller.
Even if we assume for the sake of argument that it would
have been obvious to one of ordinary skill in the art “to combine
a low frequency accelerometer [Diller] and a high frequency3
sensor [Feldmaier] to provide a sensing system capable of giving
early indication of crash severity with addition of reliable
indication of crash direction and initial velocity change,” we
find that the examiner still has not come to grips with the
“analyzing means” (claims 1 through 13) or the “microprocessor”
(claims 14 through 19) for combining and analyzing the low
frequency and the high frequency signals. For this reason, we
2Feldmaier makes clear (column 3, lines 38 through 43 and
column 4, lines 11 through 18) that low frequency signals should
be excluded because they interfere with the sensor readings of
high frequency sensors.
3Blackburn discloses (Figure 1) an A/D converter 102 for
converting a low frequency accelerometer signal into a digital
signal for processing by the microcomputer 104.
